Who Needs to File a Utah Tax Return?
Not everyone living or working in Utah is required to file a state tax return, but many individuals are. The Utah State Tax Commission sets specific rules to determine who must file. Understanding whether you need to file is the first step in the tax filing process and can help you avoid penalties or delays in receiving a refund.
You must file a Utah tax return if any of the following apply:
- You are a full-year Utah resident
If you are a full-year resident of Utah and are required to file a federal return, you must file a Utah tax return. This includes individuals with income from wages, self-employment, retirement, or other sources.
- You are a part-year or nonresident who earned income in Utah.
If you lived in Utah for only part of the year or earned income from Utah sources while living elsewhere, you must file using Form TC-40 and include the TC-40B schedule to calculate Utah income.
- You want to claim a refund for Utah taxes withheld.
If your employer withheld state taxes from your paycheck but you are not otherwise required to file, you can still complete a return to request a refund.
- You have Utah taxable income and meet filing thresholds.
Filing is required if your Utah income meets or exceeds the filing threshold, even if no taxes were withheld or you owe no tax.
- You operate a business or receive pass-through income from a Utah-based entity.
Sole proprietors, S corporation shareholders, and members of partnerships or LLCs may need to file based on their share of business income attributed to Utah.
Even if you don’t owe money, filing can help you access credits, estimate your refund, and keep your tax records accurate for several years. Filing a tax return also helps verify your income, which can be helpful when applying for loans, government assistance programs, or other financial services.
Key Utah Tax Changes for the 2024 Tax Year
Each tax year brings new rules that affect how you file and how much you owe or receive. For 2024, Utah has introduced several changes impacting individuals and small businesses.
- Lower income tax rate
The state income tax rate has been reduced from 4.65% to 4.55%. This applies to all taxpayers and affects how your Utah tax is calculated on your return.
- New child tax credit
Utah now offers a nonrefundable child tax credit of $1,000 per child between the ages of 1 and 3. This credit may help lower your tax liability if you meet income and eligibility requirements.
- PPP grant or loan addbacks
If you received Payroll Protection Program funds excluded from federal taxable income, you may need to add those amounts back into your Utah income in some instances.
- New nonprofit donation option
The Nonprofit Capacity Fund has been added as a voluntary contribution line on the Utah return. Taxpayers can donate part of their refund or add to their payment.
These changes make it essential to use updated forms, review your deductions, and estimate your tax accurately to avoid problems with filing or receiving your refund.
Utah Income Tax Forms You May Need
Choosing the proper tax form is essential to complete your Utah return correctly. The forms you need depend on your residency status, type of income, and whether you’re claiming adjustments or credits.
For Individuals
- TC-40 – Utah Individual Income Tax Return
This is the main form most individual filers use to report their income and deductions and calculate the tax owed or refund due.
- TC-40A – Utah Supplemental Schedule
Use this form to report adjustments to income, nonrefundable and refundable credits, and voluntary contributions.
- TC-40B – Non- or Part-year Resident Schedule
This schedule is required for taxpayers who either lived in Utah for only part of the year or earned income in Utah while residing in another state.
- TC-40W – Withholding Tax Schedule
Use this form to report any Utah taxes employers or other payers withhold.
For Small Business Owners
- TC-20 – Corporation Franchise and Income Tax Return
C corporations use this form to report their income and pay franchise taxes in Utah. A minimum payment is usually required.
- TC-20S – S Corporation Return
S corporations must file this form to report income passed through to shareholders, who must report that income on their returns.
- TC-65 – Partnership Return of Income
This form is required for partnerships and most multi-member LLCs that operate in Utah. Partners report their share of the income on their returns.
To ensure accuracy and avoid delays, access the latest versions of these forms directly from the Utah State Tax Commission website.
Step-by-Step Instructions to Complete Your Utah Return
Before You Begin
Start by completing your federal tax return. Utah uses your federal adjusted gross income as the starting point for state tax calculations. Gather all relevant documents, including:
- W-2s and 1099s
- Receipts for deductions or credits
- Records of Utah tax payments or estimated taxes
- Your Social Security number and dependent details
Consider using tax software or a tax preparer if you need expert help or have questions.
How to Complete Form TC-40
- Personal and Residency Information
Enter your name, address, Social Security number, and filing status. Indicate whether you’re a resident, part-year resident, or nonresident. List any qualifying dependents.
- Report Federal Adjusted Gross Income (FAGI)
Transfer your FAGI from your federal return. Then use TC-40A Part 1 to report additions and Part 2 for subtractions to determine Utah taxable income.
- Calculate Your Tax
Multiply your taxable income by 4.55% to calculate Utah income tax. Use TC-40A Parts 3 and 4 to claim nonrefundable credits. Apply the taxpayer tax credit if eligible.
- Enter Payments and Refundable Credits
Include Utah tax withheld (TC-40W), prepayments, or refundable credits (TC-40A Part 5). Subtract these from your total tax to determine your refund or balance due.
- Review Voluntary Contributions
You can use TC-40A Part 6 to make optional donations to programs such as education, military support, or the Nonprofit Capacity Fund.
- Sign and Submit Your Return
Double-check all math, attach required forms, and sign the return. Filing electronically reduces errors and helps you receive your refund faster.
Small Business Owners
- Sole Proprietors: Report your business income on your federal Schedule C. This income will flow to your Utah return through your FAGI.
- S Corporations and Partnerships: File TC-20S or TC-65 and report pass-through income on your TC-40.
- C Corporations: File TC-20 separately and pay the corporate tax directly to the state.
Following each step carefully ensures accuracy, improves your chances of a max refund, and helps you avoid hassle or processing delays.

Frequently Asked Questions (FAQs)
What if I missed the deadline to file my Utah tax return?
If you missed the tax filing deadline for your Utah tax return, file as soon as possible to reduce penalties. Utah grants an automatic six-month extension to file, but not to pay. You still owe any taxes due by the original date, or interest and fees will apply. Tax experts recommend using software or a tax preparer to complete the process correctly and avoid future issues.
Can I file my Utah tax return for free?
Yes, many Utah taxpayers have access to free tax filing options. You may qualify for programs like VITA or the Free File Alliance, which offer software and in-person guidance for eligible filers. These services make it easy to accurately prepare and file your return, especially if it's your first time or you have simple questions. Visit the Utah State Tax Commission site to find the right program.
How do I get the maximum refund on my Utah tax return?
To maximize your refund, please report all eligible deductions, credits, and withheld income. Review each form carefully and double-check for errors before signing and submitting. Filing electronically improves accuracy and often leads to rapid processing. Tax pros or expert help can also guide you in identifying opportunities to save money. Don’t forget to use updated software or services for the current year.
Should I use a tax preparer or file my taxes?
Using a tax preparer is helpful if you have complex income, own a business, or need expert help understanding deductions and credits. If your return is straightforward, you can file your taxes using software with step-by-step instructions. Both options can be beneficial, depending on your comfort level. Choose what saves you time, reduces cost, and improves accuracy based on your situation.
What are the most commonly missed deductions in Utah?
Commonly missed deductions on a Utah tax return include contributions to the my529 plan, income tax paid to another state, and the retirement tax credit. Failing to report eligible credits may reduce your refund. If you are unsure about your deductions, tax experts or a reliable program can help you identify any overlooked savings. Taking time to read and understand the instructions improves the process and reduces costly errors.
How can I estimate how much I will owe or receive?
You can estimate what you’ll owe or expect as a refund using Utah’s online calculators or most tax software. Start with your federal return, then input your Utah income, deductions, and withholdings. This helps you prepare ahead and avoid last-minute surprises. Whether you're filing your first return or have done it for several years, early access to estimates offers comforting details about your tax filing status.
How do I know if I’m filing the correct Utah tax form?
First, acknowledge your residency and income sources to file the correct Utah tax return. Full-year residents typically use Form TC-40, while part-year or nonresidents need the TC-40B schedule. Small business owners may also need forms like TC-20 or TC-65. ITaxpros, programs, or state websites offer helpful guidance. If unsure, please take a moment to carefully review the instructions for each form.
