What is PTET, and should a CRE broker elect it?
PTET ā pass-through entity tax ā is a state election that lets your S Corp pay your state income tax at the entity level and deduct it as a business expense on the federal return, sidestepping the cap on personal state-and-local tax deductions. For a broker with meaningful S Corp profit in a state that offers it, the election often produces a mid-four-figure to five-figure federal benefit. Whether it's worth it for you depends on your state, your income level, and the current SALT cap rules ā which now phase out the higher cap at upper incomes, keeping PTET valuable for many top-earning brokers.
The problem PTET solves
Since 2018, the deduction for state and local taxes (SALT) on your personal return has been capped ā originally at $10,000, with the cap raised in recent law but phased back down at higher incomes. For a broker paying $20,000, $40,000, or more in state income tax, that meant a large expense with little or no federal deduction attached to it.
States responded with a workaround the IRS formally blessed in Notice 2020-75: let the pass-through entity itself pay the state tax. Business taxes paid by an entity aren't subject to the personal SALT cap ā they're an ordinary deduction against business income. The owner then gets a credit (or income exclusion) on their personal state return so the same tax isn't paid twice.
How the math works
Illustrative only. The benefit depends on your marginal rate, how much SALT room you have left on the personal return under current law, your state's credit mechanics, and QBI interactions ā the entity-level deduction also reduces QBI income in most states' designs.
Why the current SALT cap rules make this income-sensitive
Recent federal law raised the personal SALT cap substantially ā but with a phase-down at higher incomes that brings top earners back toward the old cap. The practical effect: moderate earners in low-tax states may now get most of their SALT deduction personally and gain little from PTET, while high-earning brokers in states with meaningful income tax often remain squarely in the group PTET helps most. This is exactly the kind of rule that changes with legislation, which is why the election should be re-evaluated annually rather than set once and forgotten.
The mechanics you can't ignore
- It's an annual election with a deadline. Several states require the election early in the tax year ā New York's March 15 deadline is the famous one. Miss it and the year is gone.
- The entity must actually pay. Most states require PTET estimated payments during the year, on their own schedule, from the entity's bank account. Cash-flow planning matters.
- State designs differ. Some states give owners a credit, others an exclusion; some calculate the tax on different income bases. The savings math is state-specific.
- Not every state has one ā and if you broker deals across state lines, multistate income adds a layer that deserves professional attention.
Should you elect it?
If you're an S Corp broker with six-figure profit in a state with an income tax and a PTET regime, the election is usually worth modeling every year ā the benefit is often thousands of dollars for what amounts to paperwork and payment logistics. Election deadlines, entity-level estimates, and the annual re-evaluation are part of what we run for clients inside S Corp Management, so the decision gets made on numbers, on time, every year.
