Course Materials

This course will offer tax professionals a deep dive into composite tax provisions and withholding requirements of pass-through entities with nonresident shareholders and partners. The panel will provide an advanced level look at the specific issues facing tax advisers to pass-through entities regarding these composite return and withholding requirements.


Tax advisers working with pass-through entities must navigate the landscape of reporting and withholding where the pass-through entity has nonresident shareholders or partners. Advisers must consider whether to file a composite return and filing composites may not be the best option for some pass-throughs.

While states differ regarding their regimes for collecting tax from nonresident shareholders and partners of pass-through entities, there are common themes. Most states have a mandatory withholding scheme; however, some states provide the option to elect out of mandatory withholding, in some cases through filing composite tax returns.

A principal benefit of filing a composite return is the convenience for partners or shareholders to avoid the filing of nonresident state income tax returns. This benefit is offset by certain states, particularly those with high top marginal rates, that impose the tax at the top rate on income reported on a composite return.

Further, a composite return may preclude an individual shareholder or partner from claiming credits or deductions that may apply if the taxpayer filed a nonresident return. Tax advisers must understand various tax impacts to determine whether to advise filing a composite return.

Listen as our experienced panel offers a comprehensive view of states' approaches to composite returns and nonresident withholding for pass-through entities.
