Accounting Policies [Abstract]
Interim Financial Data	Note 1 – Interim Financial Data Basis of Presentation The information furnished in these unaudited interim financial statements for the three months ended June 30, 2015 and 2014 has been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). In the opinion of management, the unaudited financial information reflects all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. The results of operations for the three months ended June 30, 2015 do not necessarily indicate the results which may be expected for the full fiscal year ending March 31, 2016 (“fiscal 2016”). These financial statements should be read in conjunction with the Consolidated Financial Statements, significant accounting policies, and other notes to the Consolidated Financial Statements included in Toyota Motor Credit Corporation’s Annual Report on Form 10-K (“Form 10-K”) for the fiscal year ended March 31, 2015 (“fiscal 2015”), which was filed with the Securities and Exchange Commission on June 2, 2015. References herein to “TMCC” denote Toyota Motor Credit Corporation, and references herein to “we”, “our”, and “us” denote Toyota Motor Credit Corporation and its consolidated subsidiaries. Certain prior period amounts have been reclassified to conform to the current period presentation. Related party transactions presented in the Consolidated Financial Statements are disclosed in Note 14 – Related Party Transactions of the Notes to Consolidated Financial Statements. New Accounting Guidance In May 2014, the Financial Accounting Standards Board ("FASB") issued new guidance on the recognition of revenue from contracts with customers. This comprehensive standard will supersede virtually all existing revenue recognition guidance. This accounting guidance will be effective on April 1, 2018 with optional early adoption on April 1, 2017. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In February 2015, the FASB issued new guidance that amends the analysis a reporting entity must perform to determine whether it should consolidate certain legal entities. This accounting guidance is effective for us on April 1, 2016. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In April 2015, the FASB issued new guidance that requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. This accounting guidance will be effective for us on April 1, 2016. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In April 2015, the FASB issued new guidance to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. While similar guidance exists under current U.S. GAAP for cloud service providers, this update provides explicit guidance for a customer's accounting. This accounting guidance will be effective for us on April 1, 2016. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In May 2015, the FASB issued new guidance that removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. This accounting guidance will be effective for us on April 1, 2016. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In May 2015, the FASB issued new guidance that requires additional disclosures related to short-duration insurance contracts. This accounting guidance will be effective for us for the annual period beginning April 1, 2016 and for interim periods within annual periods beginning April 1, 2017. We are currently evaluating the potential impact of this guidance on our consolidated financial statements.

During the three months ended June 30, 2015, $37 million was transferred from Level 1 to Level 2 and $4 million was transferred from Level 3 to Level 2 due to changes in the transparency of inputs for determination of fair value for these instruments.

Receivables [Abstract]
Finance Receivables, Net	Note 4 – Finance Receivables, Net Finance receivables, net consist of retail and dealer accounts including accrued interest and deferred fees and costs, net of the allowance for credit losses and deferred income. Securitized receivables represent retail loan receivables that have been sold for legal purposes to securitization trusts but continue to be included in our consolidated financial statements, as discussed further in Note 10 – Variable Interest Entities. Cash flows from these securitized receivables are available only for the repayment of debt issued by these trusts and other obligations arising from the securitization transactions. They are not available for payment of our other obligations or to satisfy claims of our other creditors. Finance receivables, net consisted of the following: June 30, 2015 March 31, 2015 Retail receivables $ 38,128 $ 39,141 Securitized retail receivables 13,165 11,682 Dealer financing 15,762 15,744 67,055 66,567 Deferred origination (fees) and costs, net 655 646 Deferred income (919 ) (911 ) Allowance for credit losses Retail and securitized retail receivables (280 ) (301 ) Dealer financing (115 ) (108 ) Total allowance for credit losses (395 ) (409 ) Finance receivables, net $ 66,396 $ 65,893 Finance receivables, net and retail receivables presented in the previous table includes direct finance lease receivables, net of $314 million and $308 million at June 30, 2015 and March 31, 2015, respectively. Credit Quality Indicators We are exposed to credit risk on our finance receivables. Credit risk is the risk of loss arising from the failure of customers or dealers to meet the terms of their contracts with us or otherwise fail to perform as agreed. Retail Loan and Commercial Portfolio Segments Retail loan and commercial portfolio segments each consist of one class of finance receivables. While we use various credit quality metrics to develop our allowance for credit losses on the retail loan and commercial portfolio segments, we primarily utilize the aging of the individual accounts to monitor the credit quality of these finance receivables. Based on our experience, the payment status of borrowers is the strongest indicator of the credit quality of the underlying receivables. Payment status also impacts charge-offs. Individual borrower accounts for each class of finance receivables within the retail loan and commercial portfolio segments are segregated into aging categories based on the number of days outstanding. The aging for each class of finance receivables is updated monthly. Note 4 – Finance Receivables, Net (Continued) Dealer Products Portfolio Segment For the three classes of finance receivables within the dealer products portfolio segment (wholesale, real estate and working capital), all loans outstanding for an individual dealer or dealer group, which includes affiliated entities, are aggregated and evaluated collectively by dealer or dealer group. This reflects the interconnected nature of financing provided to our individual dealer and dealer group customers, and their affiliated entities. When assessing the credit quality of the finance receivables within the dealer products portfolio segment, we segregate the finance receivables account balances into four categories representing distinct credit quality indicators based on internal risk assessments. The internal risk assessments for all finance receivables within the dealer products portfolio segment are updated on a monthly basis. The four credit quality indicators are: · Performing – Account not classified as either Credit Watch, At Risk or Default · Credit Watch – Account designated for elevated attention · At Risk – Account where there is an increased likelihood that default may exist based on qualitative and quantitative factors · Default – Account is not currently meeting contractual obligations or we have temporarily waived certain contractual requirements The tables below present each credit quality indicator by class of finance receivable: Retail Loan Commercial June 30, 2015 March 31, 2015 June 30, 2015 March 31, 2015 Aging of finance receivables: Current $ 50,005 $ 49,684 $ 532 $ 511 30-59 days past due 549 467 9 8 60-89 days past due 137 100 1 2 90 days or greater past due 60 51 - - Total $ 50,751 $ 50,302 $ 542 $ 521 Wholesale Real Estate Working Capital June 30, 2015 March 31, 2015 June 30, 2015 March 31, 2015 June 30, 2015 March 31, 2015 Credit quality indicators: Performing $ 8,146 $ 7,993 $ 3,761 $ 3,782 $ 1,698 $ 1,643 Credit Watch 1,020 1,137 770 842 134 176 At Risk 73 60 10 37 31 32 Default 42 36 70 4 7 2 Total $ 9,281 $ 9,226 $ 4,611 $ 4,665 $ 1,870 $ 1,853 Note 4 – Finance Receivables, Net (Continued) Impaired Finance Receivables The following table summarizes the information related to our impaired loans by class of finance receivables: Impaired Individually Evaluated Finance Receivables Unpaid Principal Balance Allowance June 30, March 31, June 30, March 31, June 30, March 31, 2015 2015 2015 2015 2015 2015 Impaired account balances individually evaluated for impairment with an allowance: Wholesale $ 101 $ 76 $ 101 $ 76 $ 13 $ 14 Real estate 90 52 90 52 13 10 Working capital 37 34 37 34 34 31 Total $ 228 $ 162 $ 228 $ 162 $ 60 $ 55 Impaired account balances individually evaluated for impairment without an allowance: Wholesale $ 100 $ 105 $ 100 $ 105 Real estate 81 91 81 91 Working capital 3 2 3 2 Total $ 184 $ 198 $ 184 $ 198 Impaired account balances aggregated and evaluated for impairment: Retail loan $ 260 $ 264 $ 256 $ 261 Commercial - - - - Total $ 260 $ 264 $ 256 $ 261 Total impaired account balances: Retail loan $ 260 $ 264 $ 256 $ 261 Commercial - - - - Wholesale 201 181 201 181 Real estate 171 143 171 143 Working capital 40 36 40 36 Total $ 672 $ 624 $ 668 $ 621 As of June 30, 2015 and March 31, 2015, the impaired finance receivables balance for accounts in the dealer products portfolio segment that were on nonaccrual status was $221 million and $172 million, respectively, and there were no charge-offs against the allowance for credit losses for these finance receivables. Therefore, the impaired finance receivables balance is equal to the unpaid principal balance. As of June 30, 2015 and March 31, 2015, impaired finance receivables in the retail portfolio segment recorded at the fair value of the collateral less estimated selling costs were insignificant and therefore excluded from the table above. Note 4 – Finance Receivables, Net (Continued) The following table summarizes the average impaired loans by class of finance receivables as of the balance sheet date and the interest income recognized on these loans: Average Impaired Finance Interest Income Recognized Three Months Ended June 30, Three Months Ended June 30, 2015 2014 2015 2014 Impaired account balances individually evaluated for impairment with an allowance: Wholesale $ 89 $ 17 $ - $ - Real estate 71 27 1 - Working capital 35 23 - - Total $ 195 $ 67 $ 1 $ - Impaired account balances individually evaluated for impairment without an allowance: Wholesale $ 103 $ 50 $ - $ - Real estate 85 93 1 1 Working capital 3 4 - - Total $ 191 $ 147 $ 1 $ 1 Impaired account balances aggregated and evaluated for impairment: Retail loan $ 262 $ 317 $ 5 $ 6 Commercial - 1 - - Total $ 262 $ 318 $ 5 $ 6 Total impaired account balances: Retail loan $ 262 $ 317 $ 5 $ 6 Commercial - 1 - - Wholesale 192 67 - - Real estate 156 120 2 1 Working capital 38 27 - - Total $ 648 $ 532 $ 7 $ 7 The primary source of interest income recognized on the loans in the table above is from performing troubled debt restructurings. In addition, interest income recognized using a cash-basis method of accounting during the three months ended June 30, 2015 and 2014 was not significant. Note 4 – Finance Receivables, Net (Continued) Troubled Debt Restructuring For accounts not under bankruptcy protection, the amount of finance receivables modified as a troubled debt restructuring during the three months ended June 30, 2015 and 2014 was not significant for each class of finance receivables. Troubled debt restructurings for non-bankrupt accounts within the retail loan class of finance receivables are comprised exclusively of contract term extensions that reduce the monthly payment due from the customer. Troubled debt restructurings for accounts within the commercial portfolio class of finance receivables consist of contract term extensions, interest rate adjustments, or a combination of the two. For the three classes of finance receivables within the dealer products portfolio segment, troubled debt restructurings include contract term extensions, interest rate adjustments, waivers of loan covenants, or any combination of the three. Troubled debt restructurings of accounts not under bankruptcy protection did not include forgiveness of principal or interest rate adjustments during the three months ended June 30, 2015 and 2014. We consider finance receivables under bankruptcy protection within the retail loan and commercial classes to be troubled debt restructurings as of the date we receive notice of a customer filing for bankruptcy protection, regardless of the ultimate outcome of the bankruptcy proceedings. The bankruptcy court may impose modifications as part of the proceedings, including interest rate adjustments and forgiveness of principal. For the three months ended June 30, 2015 and 2014, the financial impact of troubled debt restructurings related to accounts under bankruptcy protection was not significant to our Consolidated Statement of Income and Consolidated Balance Sheet. Payment Defaults Finance receivables modified as troubled debt restructurings for which there was a subsequent payment default during the three months ended June 30, 2015 and 2014, and for which the modification occurred within twelve months of the payment default, were not significant for all classes of such receivables.

These amounts are aggregated with their respective portfolio segments when determining the allowance for credit losses as of June 30, 2015, as they are deemed to be insignificant for individual evaluation and we have determined that the allowance for credit losses would not be materially different if the amounts had been individually evaluated for impairment. The ending balance of finance receivables for the dealer products portfolio segment collectively evaluated for impairment as of June 30, 2015 includes $965 million in receivables, which are guaranteed by Toyota Motor Sales, U.S.A., Inc.

The ending balance of finance receivables for the dealer products portfolio segment collectively evaluated for impairment as of June 30, 2014 includes $862 million in receivables, which are guaranteed by TMS and $148 million in receivables, which are guaranteed by third party private Toyota distributors. These receivables are related to certain Toyota and Lexus dealers and other third parties to which we provided financing at the request of TMS or such private distributors.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives, Hedging Activities and Interest Expense	Note 7 – Derivatives, Hedging Activities and Interest Expense Derivative Instruments Our liabilities consist mainly of fixed and floating rate debt, denominated in various currencies, which we issue in the global capital markets, while our assets consist primarily of U.S. dollar denominated, fixed rate receivables. We enter into interest rate swaps and foreign currency swaps to hedge the interest rate and foreign currency risks that result from the different characteristics of our assets and liabilities. Our use of derivative transactions is intended to reduce long-term fluctuations in cash flows and fair value adjustments of assets and liabilities caused by market movements. All of our derivative activities are authorized and monitored by our management and our Asset Liability Committee which provides a framework for financial controls and governance to manage market risk. Credit Risk Related Contingent Features Our derivative contracts are governed by International Swaps and Derivatives Association (“ISDA”) Master Agreements. Substantially all of these ISDA Master Agreements contain reciprocal ratings triggers providing either party with an option to terminate the agreement at market value in the event of a ratings downgrade of the other party below a specified threshold. As of June 30, 2015, we have daily valuation and collateral exchange arrangements with all of our counterparties. Our collateral agreements with substantially all our counterparties include a zero threshold, full collateralization arrangement. However, due to the time required to move collateral, there may be a delay of up to one day between the exchange of collateral and the valuation of our derivatives. The aggregate fair value of derivative instruments that contain credit risk related contingent features that were in a net liability position at June 30, 2015 was $43 million, excluding adjustments made for our own non-performance risk. However, we would not be required to post additional collateral to the counterparties with which we were in a net liability position at June 30, 2015 if our credit ratings were to decline, since we fully collateralize without regard to credit ratings with these counterparties. Note 7 – Derivatives, Hedging Activities and Interest Expense (Continued) Derivative Activity Impact on Financial Statements The following tables show the financial statement line item and amount of our derivative assets and liabilities that are reported in the Consolidated Balance Sheet: As of June 30, 2015 Hedge accounting Non-hedge derivatives accounting Total Fair Fair Fair Notional value Notional value Notional value Other assets Interest rate swaps $ - $ - $ 27,318 $ 370 $ 27,318 $ 370 Foreign currency swaps 271 18 1,399 260 1,670 278 Total $ 271 $ 18 $ 28,717 $ 630 $ 28,988 $ 648 Counterparty netting and collateral held (601 ) Carrying value of derivative contracts – Other assets $ 47 Other liabilities Interest rate swaps $ - $ - $ 63,997 $ 339 $ 63,997 $ 339 Interest rate caps - - 30 - 30 - Foreign currency swaps 251 48 12,355 1,582 12,606 1,630 Total $ 251 $ 48 $ 76,382 $ 1,921 $ 76,633 $ 1,969 Counterparty netting and collateral posted (1,926 ) Carrying value of derivative contracts – Other liabilities $ 43 As of June 30, 2015, we held collateral of $138 million, which offset derivative assets, and posted collateral of $1,463 million, which offset derivative liabilities.

As of June 30, 2015, our commercial paper had a weighted average remaining maturity of 77 days, while our notes and loans payable mature on various dates through fiscal 2047. Weighted average contractual interest rates are calculated based on original notional or par value before consideration of premium or discount. The carrying value of our unsecured notes and loans payable at June 30, 2015 included $19.0 billion of unsecured floating rate debt with contractual interest rates ranging from 0 percent to 3.3 percent and $33.8 billion of unsecured fixed rate debt with contractual interest rates ranging from 0.8 percent to 9.4 percent. The carrying value of our unsecured notes and loans payable at March 31, 2015 included $17.4 billion of unsecured floating rate debt with contractual interest rates ranging from 0 percent to 3.3 percent and $35.0 billion of unsecured fixed rate debt with contractual interest rates ranging from 0.8 percent to 9.4 percent. Upon issuance of fixed rate notes, we generally elect to enter into interest rate swaps to convert fixed rate payments on notes to floating rate payments. Included in unsecured notes and loans payable are notes and loans denominated in various foreign currencies, unamortized premiums and discounts and the effects of foreign currency transaction gains and losses on non-hedged or de-designated foreign currency denominated notes and loans payable. At June 30, 2015 and March 31, 2015, the carrying values of these foreign currency denominated notes payable were $12.6 billion and $12.4 billion, respectively. Concurrent with the issuance of these foreign currency unsecured notes, we entered into currency swaps in the same notional amount to convert non-U.S. currency payments to U.S. dollar denominated payments. Our secured notes and loans payable are denominated in U.S. dollars and consist of both fixed and variable rate debt with interest rates ranging from 0.4 percent to 1.7 percent at June 30, 2015 and 0.4 percent to 1.5 percent at March 31, 2015. Secured notes and loans are issued by on-balance sheet securitization trusts, as further discussed in Note 10 – Variable Interest Entities. These notes are repayable only from collections on the underlying securitized retail finance receivables and the beneficial interests in investments in operating leases and from related credit enhancements. The carrying value adjustment on debt represents the effects of fair value adjustments to debt in hedging relationships, accrued redemption premiums, and the unamortized fair value adjustments on the hedged item for terminated fair value hedge accounting relationships. The carrying value adjustment on debt decreased by $10 million at June 30, 2015 compared to March 31, 2015 primarily as a result of a stronger U.S. dollar relative to certain other currencies in which our hedged debt is denominated.

Variable Interest Entity Consolidated Carrying Amount Assets And Liabilities [Abstract]
Variable Interest Entities	Note 10 – Variable Interest Entities Consolidated Variable Interest Entities We use one or more special purpose entities that are considered Variable Interest Entities (“VIEs”) to issue asset-backed securities to third party bank-sponsored asset-backed securitization vehicles and to investors in securitization transactions. The securities issued by these VIEs are backed by the cash flows related to retail finance receivables and beneficial interests in investments in operating leases (“Securitized Assets”). We hold variable interests in the VIEs that could potentially be significant to the VIEs. We determined that we are the primary beneficiary of the securitization trusts because (i) our servicing responsibilities for the Securitized Assets give us the power to direct the activities that most significantly impact the performance of the VIEs, and (ii) our variable interests in the VIEs give us the obligation to absorb losses and the right to receive residual returns that could potentially be significant. The following tables show the assets and liabilities related to our VIE securitization transactions that were included in our financial statements: June 30, 2015 VIE Assets VIE Liabilities Gross Net Restricted Cash Securitized Assets Securitized Assets Other Assets Debt Other Liabilities Retail finance receivables $ 764 $ 13,165 $ 12,978 $ 4 $ 11,268 $ 2 Investments in operating leases 47 1,415 1,052 18 728 - Total $ 811 $ 14,580 $ 14,030 $ 22 $ 11,996 $ 2 March 31, 2015 VIE Assets VIE Liabilities Gross Net Restricted Cash Securitized Assets Securitized Assets Other Assets Debt Other Liabilities Retail finance receivables $ 730 $ 11,682 $ 11,509 $ 4 $ 9,980 $ 3 Investment in operating leases 54 1,571 1,193 11 857 - Total $ 784 $ 13,253 $ 12,702 $ 15 $ 10,837 $ 3 Restricted cash shown in the table above represents collections from the underlying Securitized Assets and certain reserve deposits held by TMCC for the VIEs and is included as part of the Restricted Cash and Cash Equivalents on our Consolidated Balance Sheet. Gross Securitized Assets represent finance receivables and beneficial interests in investments in operating leases securitized for the asset-backed securities issued. Net Securitized Assets are presented net of deferred fees and costs, deferred income, accumulated depreciation and the allowance for credit losses. Other Assets represent used vehicles held for sale that were repossessed by or returned to TMCC for the benefit of the VIEs. The related debt of these consolidated VIEs is presented net of $1,383 million and $1,275 million of securities retained by TMCC at June 30, 2015 and March 31, 2015, respectively. Other Liabilities represents accrued interest on the debt of the consolidated VIEs. The assets of the VIEs and the restricted cash held by TMCC serve as the sole source of repayment for the asset-backed securities issued by these entities. Investors in the notes issued by the VIEs do not have recourse to us or our other assets, with the exception of customary representation and warranty repurchase provisions and indemnities. As the primary beneficiary of these entities, we are exposed to credit, residual value, interest rate, and prepayment risk from the Securitized Assets in the VIEs. However, our exposure to these risks did not change as a result of the transfer of the assets to the VIEs. We may also be exposed to interest rate risk arising from the secured notes issued by the VIEs. In addition, we entered into interest rate swaps with certain special purpose entities that issue variable rate debt. Under the terms of these swaps, the special purpose entities are obligated to pay TMCC a fixed rate of interest on certain payment dates in exchange for receiving a floating rate of interest on notional amounts equal to the outstanding balance of the secured debt. Note 10 – Variable Interest Entities (Continued) This arrangement enables the special purpose entities to mitigate the interest rate risk inherent in issuing variable rate debt that is secured by fixed rate Securitized Assets. The transfers of the Securitized Assets to the special purpose entities in our securitizations are considered to be sales for legal purposes. However, the Securitized Assets and the related debt remain on our Consolidated Balance Sheet. We recognize financing revenue on the Securitized Assets and interest expense on the secured debt issued by the special purpose entities. We also maintain an allowance for credit losses on the Securitized Assets to cover estimated probable credit losses using a methodology consistent with that used for our non-securitized asset portfolio. The interest rate swaps between TMCC and the special purpose entities are considered intercompany transactions and therefore are eliminated in our consolidated financial statements. Non-consolidated Variable Interest Entities We provide lending to Toyota dealers through the Toyota Dealer Investment Group’s Dealer Capital Program (“TDIG Program”) operated by our affiliate TMS, which has an equity position in these dealerships. Dealers participating in this program have been determined to be VIEs. We do not consolidate the dealerships in this program as we are not the primary beneficiary and any exposure to loss is limited to the amount of the credit facility. At June 30, 2015 and March 31, 2015, amounts due from these dealers that are classified as finance receivables, net in the Consolidated Balance Sheet and revenues received during the three months ended June 30, 2015 and 2014 from these dealers under the TDIG Program were not significant. We also have other lending relationships, which have been determined to be VIEs, but these relationships are not consolidated as we are not the primary beneficiary. Amounts due under these relationships were not significant.

Line Of Credit Facility [Abstract]
Liquidity Facilities and Letters of Credit	Note 11 – Liquidity Facilities and Letters of Credit For additional liquidity purposes, we maintain syndicated bank credit facilities with certain banks. 364 Day Credit Agreement, Three Year Credit Agreement and Five Year Credit Agreement In November 2014, TMCC, Toyota Credit de Puerto Rico Corp. (“TCPR”) and other Toyota affiliates entered into a $5.0 billion 364 day syndicated bank credit facility, a $5.0 billion three year syndicated bank credit facility and a $5.0 billion five year syndicated bank credit facility, expiring in fiscal 2016, 2018, and 2020, respectively. The ability to make draws is subject to covenants and conditions customary in transactions of this nature, including negative pledge provisions, cross-default provisions and limitations on certain consolidations, mergers and sales of assets. These agreements may be used for general corporate purposes and none were drawn upon as of June 30, 2015 and March 31, 2015. We are in compliance with the covenants and conditions of the credit agreements described above. Other Unsecured Credit Agreements TMCC has entered into additional unsecured credit facilities with various banks. As of June 30, 2015, TMCC had committed bank credit facilities totaling $5.8 billion of which $2.2 billion, $850 million, $1.9 billion, $450 million, and $375 million mature in fiscal 2016, 2017, 2018, 2019, and 2020, respectively. These credit agreements contain covenants and conditions customary in transactions of this nature, including negative pledge provisions, cross-default provisions and limitations on certain consolidations, mergers and sales of assets. These credit facilities were not drawn upon as of June 30, 2015 and March 31, 2015. We are in compliance with the covenants and conditions of the credit agreements described above.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 12 – Commitments and Contingencies Commitments and Guarantees We have entered into certain commitments and guarantees for which the maximum unfunded amounts are summarized in the table below: June 30, 2015 March 31, 2015 Commitments: Credit facilities commitments with vehicle and industrial equipment dealers $ 1,199 $ 1,137 Minimum lease commitments 61 60 Total commitments 1,260 1,197 Guarantees of affiliate pollution control and solid waste disposal bonds 100 100 Total commitments and guarantees $ 1,360 $ 1,297 Wholesale financing demand note facilities are not considered to be contractual commitments as they are not binding arrangements under which TMCC is required to perform. We are party to a 15-year lease agreement, which expires in 2018, with TMS for our headquarters location in the TMS headquarters complex in Torrance, California. Minimum lease commitments include $22 million and $23 million for facilities leases with affiliates at June 30, 2015 and March 31, 2015, respectively. At June 30, 2015, minimum future commitments under lease agreements to which we are a lessee, including those under the TMS lease, are as follows: Future Years ending March 31, lease 2016 $ 15 2017 20 2018 16 2019 7 2020 3 Thereafter - Total $ 61 Commitments We provide fixed and variable rate credit facilities to vehicle and industrial equipment dealers. These credit facilities are typically used for facilities refurbishment, real estate purchases, and working capital requirements. These loans are generally collateralized with liens on real estate, vehicle inventory, and/or other dealership assets, as appropriate. We obtain a personal guarantee from the vehicle or industrial equipment dealer or a corporate guarantee from the dealership when deemed prudent. Although the loans are typically collateralized or guaranteed, the value of the underlying collateral or guarantees may not be sufficient to cover our exposure under such agreements. Our credit facility pricing reflects market conditions, the competitive environment, the level of dealer support required for the facility, and the credit worthiness of each dealer. Amounts drawn under these facilities are reviewed for collectability on a quarterly basis, in conjunction with our evaluation of the allowance for credit losses. We also provide financing to various multi-franchise dealer organizations, often as part of a lending consortium, for wholesale, working capital, real estate, and business acquisitions. On April 28, 2014, the Company announced that our corporate headquarters will move from Torrance, California to Plano, Texas beginning in 2017 as part of TMC’s planned consolidation of its three North American headquarters for manufacturing, sales and marketing to a single new headquarters facility. To date, the Company has not incurred any significant costs related to employees, lease termination or other related relocation expenses as a result of this planned headquarters move. These moving costs are currently estimated to be approximately $80 million and will be expensed as incurred over the next several years. Note 12 – Commitments and Contingencies (Continued) Guarantees and Other Contingencies TMCC has guaranteed bond obligations totaling $100 million in principal that were issued by Putnam County, West Virginia and Gibson County, Indiana to finance the construction of pollution control facilities at manufacturing plants of certain TMCC affiliates. The bonds mature in the following fiscal years ending March 31: 2028 - $20 million; 2029 - $50 million; 2030 - $10 million; 2031 - $10 million; and 2032 - $10 million. TMCC would be required to perform under the guarantees in the event of non-payment on the bonds and other related obligations. TMCC is entitled to reimbursement by the affiliates for any amounts paid. TMCC receives an annual fee of $78 thousand for guaranteeing such payments. TMCC has not been required to perform under any of these affiliate bond guarantees as of June 30, 2015 and March 31, 2015. Indemnification In the ordinary course of business, we enter into agreements containing indemnification provisions standard in the industry related to several types of transactions, including, but not limited to, debt funding, derivatives, securitization transactions, and our vendor and supplier agreements. Performance under these indemnities would occur upon a breach of the representations, warranties or covenants made or given, or a third party claim. In addition, we have agreed in certain debt and derivative issuances, and subject to certain exceptions, to gross-up payments due to third parties in the event that withholding tax is imposed on such payments. In addition, certain of our funding arrangements may require us to pay lenders for increased costs due to certain changes in laws or regulations. Due to the difficulty in predicting events which could cause a breach of the indemnification provisions or trigger a gross-up or other payment obligation, we are not able to estimate our maximum exposure to future payments that could result from claims made under such provisions. We have not made any material payments in the past as a result of these provisions, and as of June 30, 2015, we determined that it is not probable that we will be required to make any material payments in the future. As of June 30, 2015 and March 31, 2015, no amounts have been recorded under these indemnification provisions. Litigation and Governmental Proceedings Various legal actions, governmental proceedings and other claims are pending or may be instituted or asserted in the future against us with respect to matters arising in the ordinary course of business. Certain of these actions are or purport to be class action suits, seeking sizeable damages and/or changes in our business operations, policies and practices. Certain of these actions are similar to suits that have been filed against other financial institutions and captive finance companies. We perform periodic reviews of pending claims and actions to determine the probability of adverse verdicts and resulting amounts of liability. We establish accruals for legal claims when payments associated with the claims become probable and the costs can be reasonably estimated. When we are able, we also determine estimates of reasonably possible loss or range of loss, whether in excess of any related accrued liability or where there is no accrued liability. Given the inherent uncertainty associated with legal matters, the actual costs of resolving legal claims and associated costs of defense may be substantially higher or lower than the amounts for which accruals have been established. Based on available information and established accruals, we do not believe it is reasonably possible that the results of these proceedings, either individually or in the aggregate, will have a material adverse effect on our consolidated financial condition or results of operations. As previously disclosed, we continue to engage in communications with the Consumer Financial Protection Bureau and the U.S. Department of Justice (together, the “Agencies”) regarding our purchases of auto finance contracts from dealers and related discretionary dealer compensation practices. As of June 30, 2015, we have recorded as a loss contingency an amount that was not material to our consolidated financial condition or results of operations. Based on the current state of discussions with the Agencies, we believe the range of reasonably possible losses in excess of the amount accrued is not material. We are continuing discussions with the Agencies and intend to achieve a mutually satisfactory resolution to these matters. However, if such resolution does not occur, we may be subject to an enforcement action. In addition, we have received a request for documents and information from the New York State Department of Financial Services relating to our lending practices (including fair lending), and we are fully cooperating with this request. We cannot predict the outcome of this request given its preliminary status.

Income Tax Disclosure [Abstract]
Income Taxes	Note 13 – Income Taxes Our effective tax rate was 34 percent for the three months ended June 30, 2015 and 37 percent for the three months ended June 30, 2014. Our provision for income taxes for the three months ended June 30, 2015 was $70 million compared to $213 million for the same period in fiscal 2015. The decrease in the provision is consistent with the decrease in our income before tax for the first quarter of fiscal 2016 compared to the same period in fiscal 2015. Additionally, our first quarter financial results reflect a favorable impact from state tax law changes. Tax-related Contingencies As of June 30, 2015, we remain under IRS examination for fiscal 2016 and 2015. The IRS examination for fiscal 2014 was concluded in the second quarter of fiscal 2016. The IRS examinations for fiscal 2013 and 2012 were concluded in the first quarter of fiscal 2015. We periodically review our uncertain tax positions. Our assessment is based on many factors including the ongoing IRS audits. For the quarter ended June 30, 2015, our assessment did not result in a material change in unrecognized tax benefits. Our deferred tax assets were $2.2 billion at June 30, 2015 and March 31, 2015, and were primarily due to the deferred deduction of allowance for credit losses and cumulative federal tax loss carryforwards that expire in varying amounts beginning in fiscal 2029 through fiscal 2035. The total deferred tax liability at June 30, 2015, net of these deferred tax assets, was $7.6 billion compared with $7.5 billion at March 31, 2015. Realization with respect to the federal tax loss carryforwards is dependent on sufficient income prior to expiration of the loss carryforwards. Although realization is not assured, management believes it is more likely than not that the deferred tax assets will be realized. The amount of the deferred tax assets considered realizable could be reduced if management’s estimates change.

The closing date of the transaction has not yet been determined and the assets to be sold are not available for immediate sale in their present condition, as the transaction is subject to several closing conditions that have not yet been satisfied. The assets represent approximately $1,042 million of finance receivables, net and $942 million of investments in operating leases, net as of June 30, 2015.

New Accounting Guidance	New Accounting Guidance In May 2014, the Financial Accounting Standards Board ("FASB") issued new guidance on the recognition of revenue from contracts with customers. This comprehensive standard will supersede virtually all existing revenue recognition guidance. This accounting guidance will be effective on April 1, 2018 with optional early adoption on April 1, 2017. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In February 2015, the FASB issued new guidance that amends the analysis a reporting entity must perform to determine whether it should consolidate certain legal entities. This accounting guidance is effective for us on April 1, 2016. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In April 2015, the FASB issued new guidance that requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. This accounting guidance will be effective for us on April 1, 2016. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In April 2015, the FASB issued new guidance to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. While similar guidance exists under current U.S. GAAP for cloud service providers, this update provides explicit guidance for a customer's accounting. This accounting guidance will be effective for us on April 1, 2016. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In May 2015, the FASB issued new guidance that removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. This accounting guidance will be effective for us on April 1, 2016. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In May 2015, the FASB issued new guidance that requires additional disclosures related to short-duration insurance contracts. This accounting guidance will be effective for us for the annual period beginning April 1, 2016 and for interim periods within annual periods beginning April 1, 2017. We are currently evaluating the potential impact of this guidance on our consolidated financial statements.
