Utah State Income Tax 2026

4.45% top marginal rate. One flat bracket, with social security taxed but offset by a retirement credit. Model the federal + state + ACA stack in one place.

What is the Utah state income tax rate in 2026?

Utah taxes income at a flat 4.45% in 2026. Example: a married couple, both 70, with $40,000 of Social Security, a $30,000 private pension and $30,000 of IRA withdrawals ($100,000 in all; the pension and IRA money split evenly between them) owes $1,388 of Utah income tax (1.4% of their income) and $5,087 of federal tax; a single 62-year-old with $24,000 of Social Security, an $18,000 pension and $18,000 of IRA withdrawals ($60,000 in all) owes $1,080 to Utah and $4,111 federal. The schedule, how Utah treats each kind of retirement income, and its local taxes follow.

How Utah taxes retirement income in 2026

Standard deduction or personal exemptionNo deduction is subtracted: the full income is taxed, and a nonrefundable taxpayer credit of 6% of $16,100 (single) / $32,200 (MFJ) is applied instead, reduced by 1.3% of taxable income above $18,213 (single), $36,426 (MFJ) or $27,320 (head of household). The credit base includes the federal additional standard deduction for each taxpayer 65 or older ($2,050 unmarried, $1,650 per married taxpayer). (Utah State Legislature; rules)
Social SecurityBenefits are in the base, but a credit removes the tax on them when income is at or below $54,000 (single), $45,000 (married filing separately) and $90,000 (married filing jointly and head of household). (Utah State Legislature; rules)
Pensions, annuities and IRA/401(k) withdrawalsNo exclusion: pension, annuity and IRA/401(k) distributions are taxed as ordinary income. (Utah State Tax Commission; rules)
Capital gainsNet long-term gain is taxed as ordinary income. Short-term gains are ordinary income. (Utah State Tax Commission; rules)

Local income taxes: none in Utah. The local income taxes the tax engine computes for 2026 are in Delaware, Indiana, Iowa, Kentucky, Maryland, Michigan, Missouri, New York, Ohio, Oregon and Pennsylvania.

In our 510,000-path Monte Carlo study of 30-year retirement outcomes, Utah retirees finished at 73.72% success rate (ranked #28 of 51 by success rate, #24 of 51 by lowest median lifetime state tax). Median 30-year state-tax cost: $56,070 — that is $56,070 more than a Wyoming retiree pays. Median terminal balance after 30 years: $918,307. State tax is part of the optimization here — the playbook below shows the federal-state-ACA stack.

The UT verdict

For a retiree planning withdrawals in 2026, Utah is a middle-of-the-road state for retirement taxation. One flat bracket, with social security taxed but offset by a retirement credit.

Utah has no dollar-capped retirement-income exclusion, so every converted dollar enters the state tax base. The marginal cost of a conversion here is the federal bracket plus the state rate plus, below 65, whatever premium tax credit crossing the 400% FPL cliff would cost you.

Live ACA cliff check

The 400% FPL cliff is a federal threshold, but the dollars at stake depend on your county's benchmark Silver premium. Adjust the inputs below — every result is computed in your browser, no data is sent to QuantCalc.

Worked example: $30k Roth conversion in Utah

Consider a married couple age 58 in Utah with $75,000 of ordinary income (their MAGI), both on ACA Marketplace coverage. They want to convert $30,000 from a traditional IRA to a Roth. The Utah state tax on that conversion is approximately $1,335 — the full amount is taxed at 4.45%. Federal income tax adds another $3,600 — the whole conversion is taxed in the federal 12% bracket. And because the conversion pushes their MAGI to $105,000 — over the 400% FPL cliff of $84,600 — they lose their full ACA premium tax credit, $22,762 a year at Utah's average benchmark Silver premium. Total cost of the $30,000 conversion: about $27,697, or an effective 92.3% marginal rate. Utah applies one rate to all taxable income, so that state figure is the full amount before any deduction Utah allows. The federal-state-ACA stack matters in Utah.

Cost breakdown

ComponentAmount
Federal income tax (12% bracket)$3,600
Utah state income tax$1,335
ACA premium tax credit clawback$22,762
Total cost on $30,000 conversion$27,697 (92.3% effective)

Scenario B (moderate): cliff-aware $34.6k conversion in Utah

A Utah couple aged 60, both on Marketplace coverage with $50K wages converts $34,600, which lifts their MAGI to exactly the $84,600 400% FPL cliff: still eligible, and they keep a premium tax credit of $22,730 a year. One more dollar of conversion would cost all of it. State tax: $1,540 — the full amount is taxed at 4.45%. Federal income tax added: $4,012 (the whole conversion is taxed in the federal 10%–12% brackets). ACA PTC preserved. Total cost: $5,552, or 16.0% effective. In moderate-tax states, the conversion size is bounded by both the IRMAA two-year lookback and the ACA cliff — not state tax alone.

What the Monte Carlo data says about Utah

QuantCalc Research ran a 30-year, 10,000-path Monte Carlo simulation for an identical representative retiree (age 60, $2M starting balance, 60/40 portfolio, $80K real annual spend) in each of the 51 U.S. jurisdictions. Here's how Utah compared to the best- and worst-case states:

How Utah treats capital gains in retirement

Utah taxes long-term capital gains as ordinary income at the same top bracket rate (4.45%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 4.45% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.

Why the ACA cliff hits hard in Utah

The 400% federal-poverty-level cliff is federal, not state-specific — but its dollar impact depends on the benchmark Silver-plan premium in your county. Utah's Marketplace pricing and your household composition determine the size of the subsidy at risk. A couple aged 58 with MAGI of exactly $84,600 still has $21,806 a year of premium tax credit at Utah's average benchmark Silver premium, and all of it is on the line. With the 2021–2025 enhanced credit expired, $1 of additional MAGI above 400% FPL eliminates the entire credit.

For 2026 the 400% FPL threshold is:

Roth conversion strategy for Utah

The UT-specific playbook depends on tier:

  1. Identify your cliff distance. Compute MAGI from all income sources (wages, capital gains, interest, dividends, traditional withdrawals). Find your headroom under 400% FPL. Use the live cliff widget above for a quick check.
  2. Stay under the cliff if you can. In Utah at 4.45%, the marginal cost of going over the cliff is federal tax + state tax + full PTC clawback. The break-even conversion size is smaller than in tax-free states.
  3. If you must go over, convert big. Once you've crossed the cliff, additional conversion dollars only cost federal + state tax (no incremental PTC loss). A "rip the bandage" conversion year can be efficient if you have many traditional dollars to move.
  4. Coordinate with capital gains and the 0% LTCG bracket. Utah taxes long-term capital gains as ordinary income at the same top bracket rate (4.45%). That stacks on top of federal LTCG (0%/15%/20%) and the 3.8% NIIT for high earners. A 'free' federal 0% LTCG harvest still costs you up to 4.45% at the state level — meaningful in this jurisdiction, particularly during Roth-conversion years when your MAGI is already elevated.
  5. Plan ahead for IRMAA. The IRMAA Medicare premium surcharge has a 2-year lookback. A Utah resident in their early 60s converting today will see IRMAA implications at 65. See RMD + IRMAA calculator for the lookback math.

What a year-end move does to your Utah and federal tax in 2026

Each move changes three bills at once: the federal return, the Utah return and, for anyone on Medicare, the IRMAA surcharge the 2026 income sets for 2028. Example: a married couple, both 72, with a $40,000 pension, $50,000 of Social Security, a $30,000 IRA withdrawal and $10,000 of long-term gains already realized in 2026, the pension, the IRA money and the conversion split evenly between them on the state return. Each row is that year with one move made, against the same year without it (negative = less tax).

How much state income tax does a retiree pay in Utah?

It depends on the kind of income.

Federal tax comes on top: $5,087 and $4,111.

Does Utah tax Social Security benefits?

In some cases. Benefits are in the base, but a credit removes the tax on them when income is at or below $54,000 (single), $45,000 (married filing separately) and $90,000 (married filing jointly and head of household). (Utah State Legislature; rules)

Does Utah tax pensions, 401(k) and IRA withdrawals?
