As of March 31, 2016 , we owned and operated 33 consolidated outlet centers, with a total gross leasable area of approximately 11.5 million square feet. We also had partial ownership interests in 9 unconsolidated outlet centers totaling approximately 2.8 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.

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, 2015 . The December 31, 2015 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 or 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. 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. We have concluded that our Savannah and Southaven joint ventures are each considered a VIE because our voting rights are disproportionate to our economic interests and substantially all of each venture's activities either involve us or are conducted on our behalf. The operating, development, leasing, and management agreements of the Savannah joint venture provide that the activities that most significantly impact the economic performance of the venture require unanimous consent. Accordingly, we determined that we are not the primary beneficiary since we do not have the power to direct the significant activities that affect the economic performance of the venture, and have applied the equity method of accounting. The carrying amount of our investment in Savannah is reflected in investments in unconsolidated joint ventures on our consolidated balance sheets and was $43.8 million as of March 31, 2016 . We are unable to estimate our maximum exposure to loss at this time because our guarantees are limited and based on the future operating performance of Savannah. The management agreement and other contractual arrangements for the Southaven joint venture give us, but not necessarily our joint venture partner, significant participating rights over activities that most significantly impact the economic performance of the ventures, thus we have concluded that we are the primary beneficiary and have consolidated the venture's balance sheet and results of operations. At March 31, 2016 , total assets of this venture were $82.8 million and total liabilities were $57.1 million . The primary classification of the assets on the consolidated balance sheets are total rental property, net of $79.2 million ; cash of $1.5 million and other assets of $2.1 million (including deferred lease costs and other intangibles) and the primary classification of the liabilities include accounts payable and accrued expenses of $4.7 million and mortgages payable net of debt origination costs of $51.5 million . These assets include only those assets that can be used to settle obligations of the VIE. The liabilities include third party liabilities and exclude intercompany balances that are eliminated in consolidation. "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. As a result of the adoption of Accounting Standards Update (ASU) No. 2015-03 Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs, our deferred debt origination costs and related accumulated amortization previously recorded in the line item “deferred debt origination costs, net” have been reclassified from assets to the respective debt line items within the liabilities section in the consolidated balance sheet as of December 31, 2015. The reclassification decreases previously reported total assets and total liabilities by $11.9 million . In February 2015, FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis. ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership and affects the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships. ASU 2015-02 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. During the first quarter of 2016, we adopted ASU No. 2015-02, "Consolidation (Topic 810): Amendments to the Consolidation Analysis" and this adoption did not have a material impact on our financial position, results of operations or cash flows.

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 March 31, 2016 Joint Venture Outlet Center Location Ownership % Square Feet (in 000's) Carrying Value of Investment (in millions) Total Joint Venture Net Debt (in millions) (1) Columbus Columbus, OH 50.0 % — $ 30.7 $ — National Harbor National Harbor, MD 50.0 % 339 5.5 85.9 RioCan Canada Various 50.0 % 902 126.4 11.9 Savannah (2) Savannah, GA 50.0 % 377 43.8 93.5 Westgate Glendale, AZ 58.0 % 411 12.3 61.9 $ 218.7 $ 253.2 Charlotte (3) Charlotte, NC 50.0 % 398 $ (1.4 ) $ 89.6 Galveston/Houston (3) Texas City, TX 50.0 % 353 (2.1 ) 64.8 $ (3.5 ) $ 154.4 As of December 31, 2015 Joint Venture Outlet Center Location Ownership % Square Feet (in 000's) Carrying Value of Investment (in millions) Total Joint Venture Net Debt (1) Columbus Columbus, OH 50.0 % — $ 21.1 $ — National Harbor National Harbor, MD 50.0 % 339 6.1 85.8 RioCan Canada Various 50.0 % 870 117.2 11.3 Savannah (2) Savannah, GA 50.0 % 377 44.4 87.6 Westgate Glendale, AZ 58.0 % 411 12.3 61.9 $ 201.1 $ 246.6 Charlotte (3) Charlotte, NC 50.0 % 398 $ (1.1 ) $ 89.6 Galveston/Houston (3) Texas City, TX 50.0 % 353 (1.5 ) 64.7 $ (2.6 ) $ 154.3 (1) Net of debt origination costs and including premiums of $2.8 million and $3.3 million as of March 31, 2016 and December 31, 2015, respectively. (2) Based on capital contribution and distribution provisions in the joint venture agreement, we expect our economic interest in the venture's cash flow to be greater than indicated in the Ownership column, which states our legal interest in this venture. As of March 31 2016, based upon the liquidation proceeds we would receive from a hypothetical liquidation of our investment based on depreciated book value, our estimated economic interest in the venture was approximately 98% . Our economic interest may fluctuate based on a number of factors, including mortgage financing, partnership capital contributions and distributions, and proceeds from gains or losses of asset sales. (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 March 31, 2016 2015 Fee: Development and leasing $ 192 $ 581 Loan guarantee 182 196 Management and marketing 747 506 Total Fees $ 1,121 $ 1,283 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 $4.1 million and $3.9 million as of March 31, 2016 and December 31, 2015 , respectively) are amortized over the various useful lives of the related assets. Columbus, Ohio During the second quarter of 2015, the joint venture purchased land for approximately $8.9 million and began construction on Tanger Outlets Columbus. We and our partner currently expect to complete construction in time to open the center during the second quarter of 2016. As of March 31, 2016 , we and our partner had each contributed $30.0 million to fund development activities. Our partner is providing development services to the joint venture and we, along with our partner, are providing joint leasing services. Once the center opens, we will provide property management, marketing and leasing services to the joint venture.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers are defined as follows: Tier Description Level 1 Observable inputs such as quoted prices in active markets Level 2 Inputs other than quoted prices in active markets that are either directly or indirectly observable Level 3 Unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions The following table sets forth our assets and liabilities that are measured at fair value within the fair value hierarchy (in thousands): Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Observable Inputs Significant Unobservable Inputs Total Fair value as of March 31, 2016 Liabilities: Interest rate swaps (other liabilities) $ (2,002 ) $ — $ (2,002 ) $ — Total liabilities $ (2,002 ) $ — $ (2,002 ) $ — Level 1 Level 2 Level 3 Quoted Prices in Active Markets for Identical Assets or Liabilities Significant Observable Inputs Significant Unobservable Inputs Total Fair value as of December 31, 2015: Liabilities: Interest rate swaps (other liabilities) $ (616 ) $ — $ (616 ) $ — Total assets $ (616 ) $ — $ (616 ) $ — Fair values of interest rate swaps are approximated using Level 2 inputs based on current market data received from financial sources that trade such instruments and are based on prevailing market data and derived from third party proprietary models based on well recognized financial principles including counterparty risks, credit spreads and interest rate projections, as well as reasonable estimates about relevant future market conditions. The estimated fair value 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): March 31, 2016 December 31, 2015 Fair value of debt $ 1,556,139 $ 1,615,833 Recorded value of debt $ 1,475,668 $ 1,551,924 With the exception of the unsecured term loan and unsecured lines of credit, that have variable rates and considered at market value, fair values of the senior notes and mortgage loans are determined using discounted cash flow analysis with an interest rate or credit spread similar to that of current market borrowing arrangements. Because the Company's senior unsecured notes are publicly traded with limited trading volume, these instruments are classified as Level 2 in the hierarchy. In contrast, mortgage loans are classified as Level 3 given the unobservable inputs utilized in the valuation. Considerable judgment is necessary to develop estimated fair values of financial instruments. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize on the disposition of the financial instruments. 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.

For the three months ended March 31, 2016 , 218,200 options were excluded from the computation and for the three months ended March 31, 2015, 252,000 options were excluded from the computation, 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	3 Months Ended

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 share-based compensation expense in general and administrative expenses in our consolidated statements of operations as follows (in thousands): Three months ended March 31, 2016 2015 Restricted common shares $ 2,939 $ 2,658 Notional unit performance awards 885 841 Options 177 114 Total share-based compensation $ 4,001 $ 3,613 Share-based compensation expense capitalized as a part of rental property and deferred lease costs were as follows (in thousands): Three months ended March 31, 2016 2015 Share-based compensation expense capitalized $ 230 $ 188 Restricted Common Share Awards During February 2016, the Company granted 286,524 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 $26.48 to $31.15 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 four 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 60,382 and 30,578 for the three months ended March 31, 2016 and 2015, respectively, and 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 $1.9 million and $1.1 million for the three months ended March 31, 2016 and 2015, respectively, and is reflected as a financing activity within the consolidated statements of cash flows. 2016 Outperformance Plan In February 2016, the Compensation Committee of Tanger Factory Outlet Centers, Inc. approved the terms of the Tanger Factory Outlet Centers, Inc. 2016 Outperformance Plan (the “2016 OPP"), a long-term incentive compensation plan. Under the 2016 OPP, the Company granted to award recipients an aggregate of 321,900 performance share units with a grant date fair value of $15.10 per unit, which may convert, subject to the achievement of the goals described below, into a maximum of 321,900 restricted common shares of the Company based on the Company’s absolute share price appreciation and its share price appreciation relative to its peer group, over the three -year measurement period from February 10, 2016 through February 9, 2019. The maximum number of shares will be earned under this plan if the Company both (a) achieves 35% or higher share price appreciation, inclusive of all dividends paid, over the three -year measurement period and (b) is in the 70th or greater percentile of its peer group for total shareholder return over the three -year measurement period. The Company expects that the value of the awards, if the Company achieves a 35% share price appreciation and is in the 70th or greater percentile of its peer group for total shareholder return over the three -year measurement period, will equal approximately $12.8 million . Any shares earned on February 9, 2019 are also subject to a time based vesting schedule, which provides that, subject to continued employment with the Company, 50% of the shares will vest on February 15, 2019 and the remaining 50% will vest on February 15, 2020. With respect to 50% of the performance share units (representing a right to receive up to 160,950 restricted shares), 20% of this portion of the award (representing a right to receive 32,190 restricted shares) will be earned if the Company’s aggregate share price appreciation, inclusive of all dividends paid during this period, equals 18% over the three -year measurement period, 60% of this portion of the award (representing a right to receive 96,750 restricted shares) will be earned if the Company’s aggregate share price appreciation, inclusive of all dividends paid during this period equals 26.5% , and 100% of this portion of the award (representing a right to receive 160,950 restricted shares) will be earned if the Company’s aggregate share price appreciation, inclusive of all dividends paid during this period, equals 35% or higher. With respect to the other 50% of the performance share units (representing a right to receive up to 160,950 restricted shares), 20% of this portion of the award (representing a right to receive up to 32,190 restricted shares) will be earned if the Company's share price appreciation inclusive of all dividends paid is in the 40th percentile of its peer group over the three -year measurement period, 60% of this portion of the award (representing a right to receive up to 96,750 restricted shares) will be earned if the Company's share price appreciation inclusive of all dividends paid is in the 55th percentile of its peer group during this period, and 100% of this portion of the award (representing a right to receive 160,950 restricted shares) will be earned if the Company's share price appreciation inclusive of all dividends paid is in the 70th percentile of its peer group or greater during this period. The peer group is based on companies included in the SNL Equity REIT index. The number of restricted shares received in respect of the performance share units 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 targets will be reduced on a dollar-for-dollar basis with respect to any dividend payments made during the measurement period.

Accounting Policies [Abstract]
New Accounting Standards	New Accounting Pronouncements In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. This ASU is effective for fiscal years beginning after December 15, 2016 including interim periods within that reporting period and may be applied on a modified retrospective basis as a cumulative-effect adjustment to retained earnings as of the date of adoption. Early adoption is permitted. We are currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07, Investments - Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting, this standard eliminates the requirement that when an existing cost method investment qualifies for use of the equity method, an investor must restate its historical financial statements, as if the equity method had been used during all previous periods. Under the new guidance, at the point an investment qualifies for the equity method, any unrealized gain or loss in accumulated other comprehensive income/(loss) ("AOCI") will be recognized through earnings. The standard is effective for interim and annual reporting periods beginning after December 15, 2016, although early adoption is permitted. The adoption of the guidance will be applied prospectively to increases in the level of ownership interest or degree of influence occurring after the new standards effective date. Additional transition disclosures are not required upon adoption. We are currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-06, Derivatives and Hedging (Topic 815) – Contingent Put and Call Options in Debt Instruments (“ASU 2016-06”), which will reduce diversity of practice in identifying embedded derivatives in debt instruments. ASU 2016-06 clarifies that the nature of an exercise contingency is not subject to the “clearly and closely” criteria for purposes of assessing whether the call or put option must be separated from the debt instrument and accounted for separately as a derivative. ASU No. 2016-06 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2016. Entities are required to apply the guidance to existing debt instruments using a modified retrospective transition method as of the period of adoption. We are currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements. In February 2016, the FASB issued ASU No. 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. 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. We are currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements. In May 2014, the FASB issued ASU No. 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. We are required to adopt the new pronouncement in the first quarter of fiscal 2018 using one of two retrospective application methods. In March and April, 2016 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) and ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. We are currently evaluating the new guidance to determine the impact it may have on our consolidated financial statements.

We also entered into four separate interest rate swap agreements, effective April 13, 2016, that fix the base LIBOR rate at an average of 1.03% on notional amounts totaling $175.0 million through January 1, 2021. In April 2016, the Company's Board of Directors declared a $0.325 cash dividend per common share payable on May 13, 2016 to each shareholder of record on April 29, 2016, and caused a $0.325 cash distribution per Operating Partnership unit to the Operating Partnership's unitholders.

As of March 31 2016, based upon the liquidation proceeds we would receive from a hypothetical liquidation of our investment based on depreciated book value, our estimated economic interest in the venture was approximately 98% . Our economic interest may fluctuate based on a number of factors, including mortgage financing, partnership capital contributions and distributions, and proceeds from gains or losses of asset sales. (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.
