Business	Business Tanger Factory Outlet Centers, Inc. and subsidiaries is one of the largest owners and operators of outlet centers in the United States and Canada. We are a fully-integrated, self-administered and self-managed real estate investment trust ("REIT") which, through our controlling interest in the Operating Partnership, focuses exclusively on developing, acquiring, owning, operating and managing outlet shopping centers. As of June 30, 2017 , we owned and operated 35 consolidated outlet centers, with a total gross leasable area of approximately 12.4 million square feet. We also had partial ownership interests in 8 unconsolidated outlet centers totaling approximately 2.4 million square feet, including 4 outlet centers in Canada. Our outlet centers and other assets are held by, and all of our operations are conducted by, Tanger Properties Limited Partnership and subsidiaries. Accordingly, the descriptions of our business, employees and properties are also descriptions of the business, employees and properties of the Operating Partnership. Unless the context indicates otherwise, the term "Company" refers to Tanger Factory Outlet Centers, Inc. and subsidiaries and the term, "Operating Partnership", refers to Tanger Properties Limited Partnership and subsidiaries. The terms "we", "our" and "us" refer to the Company or the Company and the Operating Partnership together, as the text requires. The Company owns the majority of the units of partnership interest issued by the Operating Partnership through its two wholly-owned subsidiaries, Tanger GP Trust and Tanger LP Trust. Tanger GP Trust is the sole general partner of the Operating Partnership. Tanger LP Trust holds a limited partnership interest. As of June 30, 2017 , the Company, through its ownership of Tanger GP Trust and Tanger LP Trust, owned 94,958,136 units of the Operating Partnership and other limited partners (the "Non-Company LPs") collectively owned 5,027,781 Class A common limited partnership units. Each Class A common limited partnership unit held by the Non-Company LPs is exchangeable for one of the Company's common shares, subject to certain limitations to preserve the Company's REIT status. Class B common limited partnership units, which are held by Tanger LP Trust, are not exchangeable for common shares of the Company.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited consolidated financial statements included herein have been prepared pursuant to accounting principles generally accepted in the United States of America and should be read in conjunction with the consolidated financial statements and notes thereto of the Company's and the Operating Partnership's combined Annual Report on Form 10-K for the year ended December 31, 2016 . The December 31, 2016 balance sheet data in this Form 10-Q was derived from audited financial statements. Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to the SEC's rules and regulations, although management believes that the disclosures are adequate to make the information presented not misleading. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the financial statements for the interim periods have been made. The results of interim periods are not necessarily indicative of the results for a full year. The Company currently consolidates the Operating Partnership because it has (1) the power to direct the activities of the Operating Partnership that most significantly impact the Operating Partnership’s economic performance and (2) the obligation to absorb losses and the right to receive the residual returns of the Operating Partnership that could be potentially significant. We consolidate properties that are wholly owned and properties where we own less than 100% but we control. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities ("VIE"). For joint ventures that are determined to be a VIE, we consolidate the entity where we are deemed to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance, and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. Our determination of the primary beneficiary considers all relationships between us and the VIE, including management agreements and other contractual arrangements. Investments in real estate joint ventures that we do not control but may exercise significant influence are accounted for using the equity method of accounting. These investments are recorded initially at cost and subsequently adjusted for our equity in the joint venture's net income or loss, cash contributions, distributions and other adjustments required under the equity method of accounting. For certain of these investments, we record our equity in the venture's net income or loss under the hypothetical liquidation at book value (“HLBV”) method of accounting due to the structures and the preferences we receive on the distributions from our joint ventures pursuant to the respective joint venture agreements for those joint ventures. Under this method, we recognize income and loss in each period based on the change in liquidation proceeds we would receive from a hypothetical liquidation of our investment based on depreciated book value. Therefore, income or loss may be allocated disproportionately as compared to the ownership percentages due to specified preferred return rate thresholds and may be more or less than actual cash distributions received and more or less than what we may receive in the event of an actual liquidation. In the event a basis difference is created between our underlying interest in the venture's net assets and our initial investment, we amortize such amount over the estimated life of the venture as a component of equity in earnings of unconsolidated joint ventures. We separately report investments in joint ventures for which accumulated distributions have exceeded investments in, and our share of net income or loss of, the joint ventures within other liabilities in the consolidated balance sheets because we are committed to provide further financial support to these joint ventures. The carrying amount of our investments in the Charlotte and Galveston/Houston joint ventures are less than zero because of financing or operating distributions that were greater than net income, as net income includes non-cash charges for depreciation and amortization. "Noncontrolling interests in the Operating Partnership" reflects the Non-Company LP's percentage ownership of the Operating Partnership's units. "Noncontrolling interests in other consolidated partnerships" consist of outside equity interests in partnerships or joint ventures not wholly owned by the Company or the Operating Partnership that are consolidated with the financial results of the Company and Operating Partnership because the Operating Partnership exercises control over the entities that own the properties. Noncontrolling interests are initially recorded in the consolidated balance sheets at fair value based upon purchase price allocations. Income is allocated to the noncontrolling interests based on the allocation provisions within the partnership or joint venture agreements.

Investments In Unconsolidated Real Estate Joint Ventures [Abstract]
Investments in Unconsolidated Real Estate Joint Ventures	Investments in Unconsolidated Real Estate Joint Ventures The equity method of accounting is used to account for each of the individual joint ventures. We have an ownership interest in the following unconsolidated real estate joint ventures: As of June 30, 2017 Joint Venture Outlet Center Location Ownership % Square Feet (in 000's) Carrying Value of Investment (in millions) Total Joint Venture Debt, Net (in millions) (1) Columbus Columbus, OH 50.0 % 355 $ 6.8 $ 84.3 National Harbor National Harbor, MD 50.0 % 341 2.8 86.3 RioCan Canada Various 50.0 % 924 121.6 11.1 Investments included in total assets $ 131.2 Charlotte (3) Charlotte, NC 50.0 % 398 $ (3.1 ) $ 89.8 Galveston/Houston (2)(3) Texas City, TX 50.0 % 353 (4.9 ) 64.9 Investments included in other liabilities $ (8.0 ) As of December 31, 2016 Joint Venture Outlet Center Location Ownership % Square Feet (in 000's) Carrying Value of Investment (in millions) Total Joint Venture Debt, Net (1) Columbus Columbus, OH 50.0 % 355 $ 6.7 $ 84.2 National Harbor National Harbor, MD 50.0 % 341 4.1 86.1 RioCan Canada Various 50.0 % 901 117.3 11.1 Investments included in total assets $ 128.1 Charlotte (3) Charlotte, NC 50.0 % 398 $ (2.5 ) $ 89.7 Galveston/Houston (2)(3) Texas City, TX 50.0 % 353 (3.8 ) 64.9 Investments included in other liabilities $ (6.3 ) (1) Net of debt origination costs and including premiums of $1.3 million and $1.6 million as of June 30, 2017 and December 31, 2016, respectively. (2) In June 2017, the joint venture exercised its extension option and extended the maturity date of the loan from July 2017 to July 2018. In July, the joint venture amended and restated the initial construction loan to increase the amount available to borrow from $70.0 million to $80.0 million and extended the maturity date until July 2020 with two one -year options. The amended and restated loan also changed the interest rate from LIBOR + 1.50% to an interest rate of LIBOR + 1.65% . At the closing of the amendment, the joint venture distributed approximately $14.5 million equally between the partners. (3) The negative carrying value is due to the distributions of proceeds from mortgage loans and quarterly distributions of excess cash flow exceeding the original contributions from the partners. Fees we received for various services provided to our unconsolidated joint ventures were recognized in management, leasing and other services as follows (in thousands): Three months ended Six months ended June 30, June 30, 2017 2016 2017 2016 Fee: Management and marketing $ 570 $ 797 1,112 1,544 Development and leasing 35 353 $ 67 $ 545 Loan guarantee 4 182 9 364 Total Fees $ 609 $ 1,332 $ 1,188 $ 2,453 Our investments in real estate joint ventures are reduced by the percentage of the profits earned for leasing and development services associated with our ownership interest in each joint venture. Our carrying value of investments in unconsolidated joint ventures differs from our share of the assets reported in the "Summary Balance Sheets - Unconsolidated Joint Ventures" shown below due to adjustments to the book basis, including intercompany profits on sales of services that are capitalized by the unconsolidated joint ventures. The differences in basis (totaling $3.7 million for both the period ended June 30, 2017 and the period ended December 31, 2016 ) are amortized over the various useful lives of the related assets.

The estimated fair value within the fair value hierarchy and recorded value of our debt consisting of senior unsecured notes, unsecured term loans, secured mortgages and unsecured lines of credit were as follows (in thousands): June 30, 2017 December 31, 2016 Level 1 Quoted Prices in Active Markets for Identical Assets or Liabilities $ — $ — Level 2 Significant Observable Inputs 1,143,532 1,137,976 Level 3 Significant Unobservable Inputs 602,940 566,668 Total fair value of debt $ 1,746,472 $ 1,704,644 Recorded value of debt $ 1,729,002 $ 1,687,866 Our senior unsecured notes are publicly-traded which provides quoted market rates. However, due to the limited trading volume of these notes, we have classified these instruments as Level 2 in the hierarchy. Our other debt is classified as Level 3 given the unobservable inputs utilized in the valuation. Our unsecured term loan, unsecured lines of credit and variable interest rate mortgages are all LIBOR based instruments. When selecting the discount rates for purposes of estimating the fair value of these instruments, we evaluated the original credit spreads and do not believe that the use of them differs materially from current credit spreads for similar instruments and therefore the recorded values of these debt instruments is considered their fair value. The carrying values of cash and cash equivalents, receivables, accounts payable, accrued expenses and other assets and liabilities are reasonable estimates of their fair values because of the short maturities of these instruments.

Share repurchase program [Abstract]
Share Repurchase Program	Share Repurchase Program In May 2017, we announced that our Board of Directors authorized the repurchase of up to $125.0 million of our outstanding common shares as market conditions warrant over a period commencing on May 19, 2017 and expiring on May 18, 2019. Repurchases may be made through open market, privately-negotiated, structured or derivative transactions (including accelerated stock repurchase transactions), or other methods of acquiring shares. The Company intends to structure open market purchases to occur within pricing and volume requirements of Rule 10b-18. The Company may, from time to time, enter into Rule 10b5-1 plans to facilitate the repurchase of its shares under this authorization. Between May 19, 2017 and June 2, 2017 we repurchased approximately 1.5 million common shares on the open market at an average price of $26.25 , totaling approximately $39.3 million , exclusive of commissions and related fees. The remaining amount authorized to be repurchased under the program as of June 30, 2017 was approximately $85.7 million .

When the Company issues common shares upon the exercise of options, the grant of restricted common share awards, or the exchange of Class A common limited partnership units, the Operating Partnership issues a corresponding Class B common limited partnership unit to Tanger LP trust, a wholly-owned subsidiary of the Company. Likewise, when the Company repurchases its common shares, the Operating Partnership repurchases an equivalent number of Class B common limited partnership units held by Tanger LP Trust.

The notional units are considered contingently issuable common shares and are included in earnings per share if the effect is dilutive using the treasury stock method and the common shares would be issuable if the end of the reporting period were the end of the contingency period. For the both the three and six months ended June 30, 2017 , 871,116 notional units were excluded from the computation,respectively, and for the three and six months ended June 30, 2016, 775,073 and 791,131 notional units were excluded from the computation, respectively, because these notional units either would not have been issuable if the end of the reporting period were the end of the contingency period or as they were anti-dilutive. The effect of dilutive common shares is determined using the treasury stock method, whereby outstanding options are assumed exercised at the beginning of the reporting period and the exercise proceeds from such options and the average measured but unrecognized compensation cost during the period are assumed to be used to repurchase our common shares at the average market price during the period. For both the three and six months ended June 30, 2017 , 176,300 options were excluded from the computation and for both the three and six months ended June 30, 2016, 194,900 options were excluded from the computation, respectively, as they were anti-dilutive. The assumed exchange of the partnership units held by the Non-Company LPs as of the beginning of the year, which would result in the elimination of earnings allocated to the noncontrolling interest in the Operating Partnership, would have no impact on earnings per share since the allocation of earnings to a common limited partnership unit, as if exchanged, is equivalent to earnings allocated to a common share. Certain of the Company's unvested restricted common share awards contain non-forfeitable rights to dividends or dividend equivalents. The impact of these unvested restricted common share awards on earnings per share has been calculated using the two-class method whereby earnings are allocated to the unvested restricted common share awards based on dividends declared and the unvested restricted common shares' participation rights in undistributed earnings. Unvested restricted common shares that do not contain non-forfeitable rights to dividends or dividend equivalents are included in the diluted earnings per share computation if the effect is dilutive, using the treasury stock method.

Equity-Based Compensation of the Company	Equity-Based Compensation of the Company We have a shareholder approved equity-based compensation plan, the Incentive Award Plan of Tanger Factory Outlet Centers, Inc. and Tanger Properties Limited Partnership (Amended and Restated as of April 4, 2014) (the "Plan"), which covers our independent directors, officers, employees and consultants. For each common share issued by the Company, the Operating Partnership issues one corresponding unit of partnership interest to the Company's wholly owned subsidiaries. Therefore, when the Company grants an equity-based award, the Operating Partnership treats each award as having been granted by the Operating Partnership. In the discussion below, the term "we" refers to the Company and the Operating Partnership together and the term "shares" is meant to also include corresponding units of the Operating Partnership. We recorded equity-based compensation expense in general and administrative expenses in our consolidated statements of operations as follows (in thousands): Three months ended Six months ended June 30, June 30, 2017 2016 2017 2016 Restricted common shares $ 2,387 $ 2,568 $ 4,737 $ 5,507 Notional unit performance awards 1,049 1,026 1,931 1,910 Options 68 61 128 238 Total equity-based compensation $ 3,504 $ 3,655 $ 6,796 $ 7,655 Equity-based compensation expense capitalized as a part of rental property and deferred lease costs were as follows (in thousands): Three months ended Six months ended June 30, June 30, 2017 2016 2017 2016 Equity-based compensation expense capitalized $ 264 $ 267 $ 510 $ 497 Restricted Common Share Awards During February 2017, the Company granted 253,431 restricted common shares to the Company's independent directors and the Company's senior executive officers. The grant date fair value of the awards ranged from $30.16 to $34.47 per share. The independent directors' restricted common shares vest ratably over a three year period and the senior executive officers' restricted shares vest ratably over a three or five year period. For the restricted shares issued to our chief executive officer, the restricted share agreement requires him to hold the shares for a minimum of three years following each vesting date. Compensation expense related to the amortization of the deferred compensation is being recognized in accordance with the vesting schedule of the restricted shares. For certain shares that vest during the period, we withhold shares with value equivalent to the employees' minimum statutory obligation for the applicable income and other employment taxes, and remit cash to the appropriate taxing authorities. The total number of shares withheld upon vesting was 69,886 and 60,382 for the six months ended June 30, 2017 and 2016 , respectively. No shares were withheld for the three months ended June 30, 2017 and 2016. The total number of shares withheld was based on the value of the restricted common shares on the vesting date as determined by our closing share price on the day prior to the vesting date. Total amounts paid for the employees' tax obligation to taxing authorities was $2.4 million and $1.9 million for the six months ended June 30, 2017 and 2016 , respectively. These amounts are reflected as financing activities within the consolidated statements of cash flows. 2017 Outperformance Plan In February 2017, the Compensation Committee of Tanger Factory Outlet Centers, Inc. approved the terms of the Tanger Factory Outlet Centers, Inc. 2017 Outperformance Plan (the “2017 OPP"), a long-term incentive compensation plan. Recipients receive notional units which may convert, subject to the achievement of the goals described below, into restricted common shares of the Company based on the Company’s absolute share price appreciation (or total shareholder return) and its share price appreciation relative to its peer group over a three -year measurement period. Any shares earned at the end of the three -year measurement period are subject to a time-based vesting schedule, with 50% of the shares vesting immediately following issuance, and the remaining 50% vesting one year thereafter, contingent upon continued employment with the Company through the vesting dates (unless terminated prior thereto (a) by the Company without cause, (b) by participant for good reason or (c) due to death or disability). The following table sets forth 2017 OPP performance targets and other relevant information about the 2017 OPP: Performance targets (1) Absolute portion of award: Percent of total award 50% Absolute share price appreciation range 18% - 35% Percentage of units to be earned 20%-100% Relative portion of award: Percent of total award 50% Percentile rank of peer group range (2) 40th - 70th Percentage of units to be earned 20%-100% Maximum number of restricted common shares that may be earned 296,400 Grant date fair value per share $ 16.60 (1) The number of restricted common shares received under the 2017 OPP will be determined on a pro-rata basis by linear interpolation between share price appreciation thresholds, both for absolute share price appreciation and for relative share price appreciation amongst the Company's peer group. The share price for the purposes of calculation of share price appreciation will be adjusted on a penny-for-penny basis with respect to any dividend payments made during the measurement period. (2) The peer group is based on companies included in the SNL Equity REIT index. The fair values of the 2017 OPP awards granted during the six months ended June 30, 2017 were determined at the grant dates using a Monte Carlo simulation pricing model and the following assumptions: Risk free interest rate (1) 1.52 % Expected dividend yield (2) 3.4 % Expected volatility (3) 19 % (1) Represents the interest rate as of the grant date on US treasury bonds having the same life as the estimated life of the restricted unit grants. (2) The dividend yield is calculated utilizing the dividends paid for the previous five-year period. (3) Based on a mix of historical and implied volatility for our common shares and the common shares of our peer index companies over the measurement period. 2014 Outperformance Plan On December 31, 2016, the measurement period for the 2014 Outperformance Plan ('the 2014 OPP") expired. Based on the Company’s absolute share price appreciation (or total shareholder return) over the three year measurement period, we issued 184,455 restricted common shares in January 2017, with 94,663 vesting immediately and the remaining 89,792 vesting in January one year thereafter, contingent upon continued employment with the Company through the vesting date. Our relative total shareholder return for the 2014 OPP did not meet the minimum share price appreciation and no shares were earned under this component of the 2014 OPP.

Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In May 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. ASU 2017-09 amends the scope of modification accounting for share-based payment arrangements, and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. ASU 2017-07 is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period. We are currently evaluating the impact of adopting the new guidance, but we do not expect the adoption to have a material impact on our consolidated financial statements. In February 2017, the FASB issued ASU 2017-05, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets." ASU 2017-05 clarifies the definition of an in-substance nonfinancial asset and changes the accounting for partial sales of nonfinancial assets to be more consistent with the accounting for a sale of a business pursuant to ASU 2017-01. This update is effective for interim and annual periods beginning after December 15, 2017 using a full retrospective or modified retrospective method and is required to be adopted in conjunction with ASU 2014-09, "Revenue from Contracts with Customers" discussed below. We will adopt ASU 2017-05 effective January 1, 2018, along with our adoption of ASU 2014-09, using the modified retrospective approach. We are currently evaluating the impact this standard may have on our consolidated financial statements. Subsequent to adoption, we believe most of our future contributions of nonfinancial assets to our joint ventures where we cease to have a controlling financial interest, if any, will result in the recognition of a full gain or loss as if we sold 100% of the nonfinancial asset and we will also measure our retained interest at fair value. In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business (Topic 805). ASU 2017-01 clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. ASU 2017-01 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted. The update should be applied prospectively. We early adopted this standard on January 1, 2017. We believe most of our future acquisitions of operating properties will qualify as asset acquisitions and certain transaction costs associated with these acquisitions will be capitalized. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This ASU requires that a statement of cash flows explain the change during the period in cash, cash equivalents, and amounts generally described as restricted cash. Amounts generally described as restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The update should be applied retrospectively to each period presented. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. We plan to adopt this pronouncement for our fiscal year beginning January 1, 2018, and the pronouncement will result in changes to our consolidated statements of cash flows such that restricted cash amounts will be included in the beginning-of-period and end-of-period cash and cash equivalents totals. In August 2016, the FASB issued ASU 2016-15, the Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force), which finalizes Proposed ASU No. EITF-15F of the same name, and addresses stakeholders’ concerns regarding diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. This ASU is effective for fiscal years beginning after December 15, 2017 and for interim periods within those fiscal years, with early adoption permitted. The ASU should be adopted using a retrospective transition approach. We are currently evaluating the impact of adopting the new guidance, but we do not expect the adoption to have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which requires measurement and recognition of expected versus incurred credit losses for financial assets held. This ASU will be applied on a prospective basis for fiscal years and interim periods beginning after December 15, 2019, with early adoption permitted for fiscal years beginning and interim periods beginning after December 15, 2018. We are currently evaluating the impact of adopting the new guidance, but we do not expect the adoption to have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases. ASU 2016-02, codified in ASC 842, amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU 2016-02 will be effective beginning in the first quarter of 2019. Early adoption of ASU 2016-02 as of its issuance is permitted. We will adopt ASU 2016-02 effective January 1, 2019. The new leases standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. Based on a preliminary assessment, we expect our significant operating lease commitments, primarily ground leases, will be required to be recognized as operating lease liabilities and right-of-use assets upon adoption, resulting in an increase in the assets and liabilities on our consolidated balance sheets. Upon adoption, we anticipate separating lease components from nonlease components, which will be evaluated under ASU 2014-09, as described below. We are continuing our evaluation, which may identify additional impacts this standard will have on our consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in ASC 605, Revenue Recognition. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 applies to all contracts with customers, except those that are within the scope of other topics in the FASB's Accounting Standards Codification, including real estate lease contracts, which the majority of our revenue is derived from. We are required to adopt the new pronouncement in the first quarter of fiscal 2018 using one of two retrospective application methods. In March 2016, April 2016, May 2016 and February 2017, the FASB issued the following amendments to clarify the implementation guidance: ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, and ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606)—Narrow-Scope Improvements and Practical Expedients. We will adopt ASU 2014-09 effective January 1, 2018 using the modified retrospective approach. We have identified our revenue streams that we believe will be impacted by the new standard, which are service revenue from management, marketing, development, and leasing fees . While the total revenue recognized over time would not differ under the new guidance, the recognition pattern would be different. We are in the process of evaluating the impact on our consolidated financial statements and internal accounting processes. We currently do not expect the adoption of ASU 2014-09 or related amendments and modifications by the FASB to have a material impact on the amount of revenue we recognize in our consolidated financial statements but we do expect to have additional disclosure as required by the adoption of ASU 2014-09.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events In July 2017, the Company's Board of Directors declared a $0.3425 cash dividend per common share payable on August 15, 2017 to each shareholder of record on July 31, 2017, and the Trustees of Tanger GP Trust declared a $0.3425 cash distribution per Operating Partnership unit to the Operating Partnership's unitholders. In July 2017, we completed an underwritten public offering of $300.0 million of our 3.875% senior notes due 2027 (the "2027 Notes"). The 2027 Notes priced at 99.579% of the principal amount to yield 3.926% to maturity. The 2027 Notes pay interest semi-annually at a rate of 3.875% per annum and mature on July 15, 2027. The estimated net proceeds from the offering, after deducting the underwriting discount and offering expenses, were approximately $295.9 million . In August 2017, we used the net proceeds from the sale of the 2027 Notes, together with borrowings under our unsecured lines of credit, to redeem all of our 6.125% senior notes due 2020 (the "2020 Notes") (approximately $300.0 million in aggregate principal amount outstanding). The 2020 Notes were redeemed at par plus a “make-whole” premium of approximately $34.1 million .

Accounting Policies [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements In May 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. ASU 2017-09 amends the scope of modification accounting for share-based payment arrangements, and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. ASU 2017-07 is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period. We are currently evaluating the impact of adopting the new guidance, but we do not expect the adoption to have a material impact on our consolidated financial statements. In February 2017, the FASB issued ASU 2017-05, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets." ASU 2017-05 clarifies the definition of an in-substance nonfinancial asset and changes the accounting for partial sales of nonfinancial assets to be more consistent with the accounting for a sale of a business pursuant to ASU 2017-01. This update is effective for interim and annual periods beginning after December 15, 2017 using a full retrospective or modified retrospective method and is required to be adopted in conjunction with ASU 2014-09, "Revenue from Contracts with Customers" discussed below. We will adopt ASU 2017-05 effective January 1, 2018, along with our adoption of ASU 2014-09, using the modified retrospective approach. We are currently evaluating the impact this standard may have on our consolidated financial statements. Subsequent to adoption, we believe most of our future contributions of nonfinancial assets to our joint ventures where we cease to have a controlling financial interest, if any, will result in the recognition of a full gain or loss as if we sold 100% of the nonfinancial asset and we will also measure our retained interest at fair value. In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business (Topic 805). ASU 2017-01 clarifies the definition of a business and provides further guidance for evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. ASU 2017-01 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted. The update should be applied prospectively. We early adopted this standard on January 1, 2017. We believe most of our future acquisitions of operating properties will qualify as asset acquisitions and certain transaction costs associated with these acquisitions will be capitalized. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This ASU requires that a statement of cash flows explain the change during the period in cash, cash equivalents, and amounts generally described as restricted cash. Amounts generally described as restricted cash should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The update should be applied retrospectively to each period presented. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted. We plan to adopt this pronouncement for our fiscal year beginning January 1, 2018, and the pronouncement will result in changes to our consolidated statements of cash flows such that restricted cash amounts will be included in the beginning-of-period and end-of-period cash and cash equivalents totals.

(2) In June 2017, the joint venture exercised its extension option and extended the maturity date of the loan from July 2017 to July 2018. In July, the joint venture amended and restated the initial construction loan to increase the amount available to borrow from $70.0 million to $80.0 million and extended the maturity date until July 2020 with two one -year options. The amended and restated loan also changed the interest rate from LIBOR + 1.50% to an interest rate of LIBOR + 1.65% . At the closing of the amendment, the joint venture distributed approximately $14.5 million equally between the partners. (3) The negative carrying value is due to the distributions of proceeds from mortgage loans and quarterly distributions of excess cash flow exceeding the original contributions from the partners.
