The operations of a partnership are generally not subject to income taxes because its income is taxed directly to its partners.

The Partnership is subject to the Texas margin tax, which is considered a state income tax, and is included in income tax expense on the Consolidated Statements of Operations. The Texas margin tax restructured the state business tax by replacing the taxable capital and earned surplus components of the existing franchise tax with a new "taxable margin" component. Since the tax base on the Texas margin tax is derived from an income-based measure, the margin tax is construed as an income tax and, therefore, the recognition of deferred taxes applies to the margin tax. The impact on deferred taxes as a result of this provision is immaterial. State income taxes attributable to the Texas margin tax of $1,048, $1,137 and $753 were recorded in income tax expense for the years ended December 31, 2015, 2014 and 2013, respectively.

A current income tax liability of $985, and $1,174 existed at December 31, 2015 and 2014, respectively.

Cash paid for income taxes was $1,237, $1,167, and $9,789 for the years ended December 31, 2015, 2014 and 2013, respectively.

The Bipartisan Budget Act of 2015 provides that any tax adjustments resulting from partnership audits will generally be determined, and any resulting tax, interest and penalties collected, at the partnership level for tax years beginning after December 31, 2017. The Bipartisan Budget Act of 2015 allows a partnership to elect to apply these provisions to any return of the partnership filed for partnership taxable years beginning after the date of the enactment, November 2, 2015. The Partnership does not intend to elect to apply these provisions for any tax return filed for partnership taxable years beginning before January 1, 2018.
