14. Income Taxes

WNRL is treated as a publicly-traded partnership for federal and state income tax purposes, however, Western Refining Product Transport, LLC ("WRPT") (a wholly-owned subsidiary) is taxed as a corporation for federal and state tax purposes. Taxes on net income for WNRL and its subsidiaries generally are borne by our partners through the allocation of taxable income. The aggregate difference in the basis of our net assets for financial and tax reporting purposes cannot be readily determined as we do not have access to information about each partner's tax attributes in us. Our deferred income tax liabilities and income tax expense result from our taxable subsidiary, WRPT. In addition, tax expense is recorded as it relates to state laws that apply to entities organized as partnerships, primarily in the state of Texas. Our deferred income tax liability as of June 30, 2017 and December 31, 2016 was $0.1 million and $0.6 million, respectively. For the three and six months ended June 30, 2017 and 2016, we had an income tax benefit of $0.3 million and $0.4 million and income tax expense of $0.2 million and $0.5 million, respectively. Our effective tax rates for the three and six months ended June 30, 2017 and 2016, were (1.4)%, (0.9)%, 2.1% and 2.9%, respectively.

As of June 30, 2017 and December 31, 2016, we had no unrecognized tax benefit liability. No interest or penalties were recognized related to income taxes during the three and six months ended June 30, 2017 and 2016.
