Pass-Through Entity Tax Elections Explained

Many states now offer an optional pass-through entity tax, often abbreviated PTET. It allows an S corporation or partnership to pay state income tax at the entity level on behalf of its owners. The main appeal is federal: the entity-level state tax is generally deductible in computing the entity's income, which reduces the income passed through to owners. This can work around the federal limit on the deduction for state and local taxes on personal returns.

Why These Elections Exist

Legislation in 2017 capped the deduction for state and local taxes for individuals. States responded by creating elective entity-level taxes, and the IRS issued guidance indicating that such payments by a partnership or S corporation are deductible at the entity level. Later federal legislation adjusted the individual cap, but the entity-level approach continues to exist in many states. Owners should confirm the current federal and state framework, since it has changed over time and may change again.

How It Generally Works

The entity elects into the regime, computes state tax on the qualifying income of participating owners, and pays the tax to the state, often through estimated payments and an annual return. The entity deducts the tax when computing federal income. Owners typically receive a credit or a deduction on their state return to avoid double taxation, though how this works differs by state. Some states require all owners to participate. Others allow election by owner or by class.

Who Considers It

Owners who itemize and whose state income tax exceeds the personal deduction limit may find the election helpful. Owners in states with high income tax may be more likely to benefit. Owners who do not itemize, or whose state tax is small, may see little benefit. Owners with residents of different states can face complexity, since credits and rates may not align.

Timing and Payment Mechanics

Election deadlines and payment schedules vary widely. Some states require the election early in the year, and some require an estimated payment before year end to be deductible in that year. Missing a deadline can mean losing the benefit. Coordinating the payment with the entity's cash flow is important since it is a large outflow.

Interaction with Other Rules

The deduction reduces qualified business income and can affect the qualified business income deduction. It may also affect basis and the amount reported on Schedules K-1. If owners receive a state credit for the tax paid, the credit's effect on the return should be considered. Some states offer refundable credits and others limit them. See The Qualified Business Income Deduction (Section 199A).

Multi-State Owners

If the entity operates in several states, each state may have a different PTET regime, or none at all. A nonresident owner may be subject to tax in the state of source income, and the state where the owner lives may or may not give a credit for taxes paid by the entity. Reviewing all the states involved is important. See Multi-State Tax Issues for Business Owners.

A Hypothetical Illustration

Consider an S corporation with two owners in a state that offers a PTET. The owners itemize but their combined state and local taxes exceed the federal cap. The entity elects into PTET, makes required estimated payments, deducts the tax, and issues K-1s reflecting reduced income. The owners then claim the state credit. The tax result depends on many facts, and the example is meant to illustrate the flow only.

Risks and Considerations

• Deadlines can be tight, and errors can eliminate the benefit.
• The rules may change if federal or state law changes.
• The election may create cash flow strain.
• Owners with different circumstances may not all benefit equally.
• Coordination with estimated taxes is essential.

Questions to Ask

1. Does my state offer a PTET and what are the election deadlines?
2. What is the estimated benefit for each owner?
3. How will payments be funded and when are they due?
4. Do any owners live in states without a matching credit?

Estimated Payment Planning

Because many PTET regimes require payments during the year, build the payments into your cash flow forecast. Underpayments can cause penalties or lose the federal deduction for the year. Confirm whether payments made after year end can count for the prior year in your state, since practices vary. Keep confirmation of each payment, and reconcile the total to the entity's return.

Review With Your Advisor Before Electing

Have your advisor model the owners' returns with and without the election before making it. The result can differ among owners, and the best decision may not be the same every year.
