Utah has a flat income tax rate which applies to both single and joint filers. The Federal Income Tax, in contrast to the Utah income tax, has multiple tax brackets with varied bracket width for single or joint filers.

• Single Tax Brackets
• Couples Tax Brackets

You can use the income tax estimator to the left to calculate your approximate Utah and Federal income tax based on the most recent tax brackets.

Keep in mind that this estimator assumes all income is from wages, assumes the standard deduction, and does not account for tax credits.

For a more detailed estimate that takes these factors into account, click "View Detailed Estimate" (this will will redirect to an external website).

When calculating your Utah income tax, keep in mind that the Utah state income tax brackets are only applied to your adjusted gross income (AGI) after you have made any qualifying deductions.

Qualifying deductions might include an itemized deduction, the Utah standard deduction, exemptions for dependants, business expenses, etc.

Remember that Utah may have very different deduction laws from the Federal Income Tax, so you may have to write a whole new list of deductions for your Utah income tax return.
