Utah taxes your income at a flat rate, and the state also collects sales tax

Utah has a flat income tax rate of 4.65% on all taxable income, regardless of how much you earn. This means a teacher and a surgeon pay the same percentage, though the surgeon pays more in total dollars. Utah also charges sales tax, which varies by location but starts at 4.85% statewide and can reach 8.85% or higher when your city or county adds their own rate on top.

You owe Utah income tax if you live in the state or earned money there during the year. The state taxes wages, self-employment income, investment gains, and retirement withdrawals. Some income is exempt — Social Security benefits, for example, are not taxed by Utah, and certain retirement account withdrawals may be excluded depending on your age and income.

Utah does not tax groceries or prescription medications, which is one reason the overall tax burden feels lighter than in some neighboring states. However, you pay sales tax on almost everything else: clothing, gas, restaurant meals, and services.

Key Takeaways

Who has to file a Utah state tax return

You must file a Utah state return if your income exceeds the filing threshold for your situation. For 2024, a single person with at least $3,300 in income must file. The threshold is higher for married couples filing jointly — currently $6,600 — and different again for dependents and those over 65.

Even if your income falls below the threshold, you should file if you had taxes withheld from your paychecks or made estimated tax payments. Filing allows you to claim a refund of any overpayment. Self-employed people and those with investment income should also file, because Utah taxes these earnings and you may owe more than what was withheld.

If you moved to Utah partway through the year, you may owe Utah tax only on the income you earned after you arrived, depending on when you established residency. Contact the Utah State Tax Commission if your situation is unclear.

How to calculate what you owe

Start with your federal taxable income — the number you use on your federal return — and make adjustments for Utah-specific rules. Some deductions allowed by the federal government are not allowed by Utah, and vice versa. For example, Utah allows a deduction for certain retirement account contributions that federal tax does not, and Utah has its own rules about what counts as business income for self-employed people.

Once you have your Utah taxable income, multiply it by 4.65%. That is your income tax liability before any credits. Then subtract any credits you may have access to for, such as the Earned Income Tax Credit (which Utah mirrors from the federal version) or the Dependent Exemption Credit. The result is what you owe, minus any taxes already withheld from your paychecks.

If you are self-employed, you also owe self-employment tax to the federal government, but Utah does not charge a separate self-employment tax. However, you still pay the 4.65% income tax on your net self-employment earnings.

Deductions and credits available in Utah

Utah allows you to claim either the standard deduction or itemize deductions, just as you do on your federal return. The standard deduction amounts are set by Utah and are usually lower than the federal amounts. For 2024, the Utah standard deduction for a single filer is $3,300, and for married filing jointly it is $6,600.

If you itemize, you can deduct state and local taxes (SALT), mortgage interest, charitable donations, and medical expenses that exceed a certain threshold — the same categories as federal tax, though Utah may have different limits. You cannot deduct federal income tax paid to another state, but you can deduct Utah income tax if you itemize.

Utah offers several credits that reduce your tax dollar-for-dollar. The Earned Income Tax Credit provides money back if you work and earn below a certain income threshold. The Dependent Exemption Credit gives you a credit for each dependent. Taxpayers over 65 may may have access to for the Senior Tax Credit. Check the Utah State Tax Commission website to see which credits match your situation.

Sales tax and what it applies to

Utah's base sales tax rate is 4.85%, but most people pay more because cities and counties add their own rates on top. Salt Lake City, for example, adds 1.25%, bringing the total to 6.1%. Some counties reach 8.85% or higher. The rate you pay depends on where you make the purchase, not where you live.

Sales tax applies to tangible goods — items you can touch and take home. Clothing, electronics, furniture, and vehicles are all taxed. Groceries and prescription medications are exempt. Restaurant meals and prepared foods are taxed, but raw ingredients you buy at a grocery store are not.

Services are generally not taxed in Utah, with some exceptions. Haircuts, car repairs, and plumbing work are usually not subject to sales tax. However, if you buy a service bundled with a product — for example, installation of carpet you purchase — the entire transaction may be taxed. When in doubt, ask the seller whether sales tax applies.

How to file your Utah state return

You file using Form TC-40, Utah's individual income tax return. You can file on paper by mailing it to the Utah State Tax Commission, or you can file electronically through the state's website or through tax software that supports Utah returns. Electronic filing is faster and reduces errors.

The important date to file is the same as the federal important date, usually April 15. If you cannot file by then, you can request an extension, which gives you until October 15 to submit your return. An extension to file is not an extension to pay — if you owe money, you should pay by April 15 to avoid penalties and interest, even if you file late.

Gather your W-2 forms from employers, 1099 forms for self-employment or investment income, and records of any deductions or credits you plan to claim. If you use tax software, it will walk you through the Utah questions and calculate your liability. If you file on paper, follow the instructions on the Form TC-40 booklet, which the state provides free on its website.

Tax credits for families and seniors

The Dependent Exemption Credit is worth $25 per dependent for most filers, though the amount phases out at higher incomes. You claim it for each child or other dependent you support. Unlike the federal Child Tax Credit, Utah's credit does not increase based on the child's age.

The Senior Tax Credit applies if you are 65 or older and meet income limits. The credit amount depends on your age and income, and it is designed to offset some of the tax burden on fixed incomes. You must file a return to claim it, even if your income is below the filing threshold.

The Earned Income Tax Credit (EITC) is available to low-income workers and mirrors the federal version. If you work and earn below the income limit — which varies by family size — you may receive a refund larger than the taxes you paid. This credit is especially valuable for families with children.

Frequently Asked Questions

Do I have to pay Utah income tax if I work remotely for a company in another state?

Yes, if you live in Utah and work remotely, you owe Utah income tax on your wages. Your employer should withhold Utah tax from your paychecks. If they do not, you are responsible for paying it when you file your return. Some states have reciprocal agreements that exempt workers from one state's tax if they live in another, but Utah does not have these agreements with most states.

What happens if I do not file a Utah tax return when I owe taxes?

The Utah State Tax Commission can assess penalties and interest on unpaid taxes. Penalties start at 5% of the unpaid tax and can increase if the return is very late. Interest accrues monthly on the unpaid balance. If you owe money, file as soon as you can, even if you cannot pay in full — the penalties are smaller if you file on time and pay late than if you file late.

Can I deduct property taxes I pay to Utah counties?

Yes, if you itemize deductions. Property taxes paid to Utah counties are deductible on your state return. However, the federal government limits the total state and local tax deduction (SALT) to $10,000 per year, so if you also deduct state income tax and sales tax, your property tax deduction may be reduced or eliminated.

Does Utah tax retirement account withdrawals?

Most retirement account withdrawals are subject to Utah income tax. However, withdrawals from certain accounts — such as Roth IRAs and some military retirement pensions — may be exempt. Social Security benefits are not taxed by Utah. Check with the Utah State Tax Commission or a tax professional about your specific retirement income.

What is the difference between filing status on my federal and Utah returns?

Your filing status should be the same on both returns. Utah recognizes the same filing statuses as the federal government: single, married filing jointly, married filing separately, head of household, and may have access to widow or widower. Your filing status determines your standard deduction and which credits you can claim.
