Utah's pass-through entity tax (PTET) lets an S corporation or partnership pay Utah income tax on its owners' share of profit, instead of each owner paying it on a personal return. The business can deduct that payment on its federal return, which sidesteps the federal cap on state and local tax (SALT) deductions. It helps most when an owner's personal SALT deduction is capped or phased down, and it helps little when the owner would not have itemized anyway.
What is the Utah pass-through entity tax?
Most small businesses in Utah are pass-throughs. The S corporation or partnership files a return, but the profit flows through to the owners, who pay the tax on their own returns. Since 2018 the federal deduction for state and local taxes on a personal return has been capped. A business, though, can deduct state taxes it pays as an ordinary business expense.
In 2020 the IRS said, in Notice 2020-75, that state taxes paid by the entity itself are deductible by the entity. Utah responded with an elective entity-level tax, available starting with the 2022 tax year. The business elects in, pays Utah tax on its owners' share of income at the individual rate, and each owner adds that tax back to their Utah income and claims a matching credit. The election is in Utah Code section 59-10-1403.2. The owner's credit is nonrefundable: any part above the owner's Utah tax can carry forward for up to ten years, with no carryback (Utah Code section 59-10-1045, as amended in 2025).
Utah's individual rate was 4.5% for the 2025 tax year and is 4.45% for 2026. The entity-level tax uses the same rate (Utah Code sections 59-10-104 and 59-10-1403.2, current as of October 2026).
Why does the SALT cap matter here?
The July 2025 federal tax law (Public Law 119-21) raised the personal SALT cap to $40,000 for 2025, rising 1% a year through 2029, so $40,400 for 2026. In 2030 the cap returns to $10,000. The law also phases the cap down by 30 cents for each dollar of modified adjusted gross income above $505,000 for 2026, but never below $10,000 (Internal Revenue Code section 164(b)(7), as amended by Public Law 119-21, July 2025).
That phase-down is the key. A Utah owner with a large profit year can lose most of the higher cap. Their Utah income tax and property tax then stop counting on the personal return. Run through the entity instead, the Utah tax on business income is deducted before it ever reaches the owner's return, so the cap does not bite on that portion.
The election does not lower your Utah tax. It changes where the federal deduction lands.
Who tends to benefit from the PTET election?
- Owners with high income. Once income is in the phase-down range, the personal SALT deduction shrinks, and the entity-level deduction becomes the only way to get federal credit for that state tax.
- Owners who already itemize. If property tax, mortgage interest and charitable gifts already put you over the standard deduction, every extra dollar of deductible state tax counts.
- Profitable S corporations and partnerships. The benefit scales with profit. A business with thin or negative income has little Utah tax to move.
Who may not benefit?
- Owners who take the standard deduction. If you would not itemize, moving state tax off your personal return changes nothing on that side, though the entity deduction can still reduce income. The math needs to be run.
- Owners well under the SALT cap. If your total state and local taxes already fit inside the 2026 cap, the personal deduction is already working.
- Businesses with owners in mixed situations. The election is made by the entity. Partners in different brackets or different states can come out differently.
What are the side effects to check?
The entity-level tax is a business deduction, so it lowers the profit that flows through. That can reduce the 20% qualified business income (QBI) deduction a little, because QBI is calculated on that lower number. It can also change the result of any formula that depends on profit, such as a retirement plan contribution based on earnings.
Cash flow changes too. The business now makes the Utah payments, often as estimated payments during the year, rather than the owners. Owners with other income or other states involved need to see how the credit lands on each return.
And the election is annual. A choice that worked last year is not automatically right this year, especially in a year with an unusual sale, a big bonus or a change in ownership.
A hypothetical example
Hypothetical. A married couple owns a Utah S corporation that earns well over $500,000 of profit in a year. With income that high, their personal SALT deduction is phased most of the way down. If the S corporation elects into the PTET, the Utah tax on that profit is paid and deducted at the entity level, and the couple claims a credit for it on their Utah return. Their Utah tax is roughly the same. Their federal taxable income is lower by the amount of Utah tax that the cap would otherwise have stopped. The size of that difference depends on their bracket, their other deductions and the exact rules for the year.
When do you decide?
Before the tax year ends, not with the return. Utah treats a payment of the entity-level tax made on or before the last day of the business's tax year as the election, and that election cannot be undone or refunded (Utah Code section 59-10-1403.2). The business reports it on form TC-75, filed electronically by that same day, which is December 31 for a calendar-year business (Utah State Tax Commission, 2025 TC-65 and TC-20S instructions). A projection in the fall, while there is still time to size the payment, is the natural moment.
If you own an S corporation or partnership and have never asked whether the election fits your numbers, it is a useful question to bring to a tax projection. Our tax strategy work is led by a CPA inside the firm, and this is the kind of year-by-year decision that page describes.
