Utah Payroll Taxes Guide →Short Answer
This Utah paycheck calculator estimates net take-home pay after federal income tax withholding, Social Security (6.2%), Medicare (1.45%), and the Utah income tax. Utah withholds a single flat rate of 4.5 percent on annual wages, then subtracts a base allowance (a low-income credit) that shrinks by 1.3 percent of wages above the exemption threshold. For a single Utah worker earning $65,000 per year paid biweekly, gross pay is about $2,500 per period, and net take-home is roughly $1,969 after about $227 of federal withholding, FICA, and about $113 of Utah income tax. Utah has no local wage tax and no state disability, family leave, or employee unemployment deduction.
Key Takeaways
- Utah withholds a flat income tax rate on every paycheck. This calculator applies the Utah State Tax Commission Publication 14 method: multiply annual wages by 4.5 percent, subtract a base allowance that tapers off with income, and divide by pay periods.
- Utah's base allowance is not a per-allowance wage exemption. It is a fixed low-income credit ($450 single / $900 married for 2025) that is reduced by 1.3 percent of annual wages above $9,107 (single) or $18,213 (married), so it phases out as income rises.
- Above roughly $43,700 (single) or $87,400 (married) the base allowance is fully phased out, so most full-time Utah workers pay an effective flat 4.5 percent of Utah wages.
- Utah has no separate state W-4. The employer uses your federal W-4 marital status: single, MFS, and head of household use the single schedule; married filing jointly uses the married schedule. No W-4 on file means a flat 4.5 percent with no base allowance.
- Federal income tax uses the IRS Publication 15-T percentage method on annualized wages. Social Security is 6.2% up to the 2025 wage base of $176,100; Medicare is 1.45% with no cap plus a 0.9% surtax that employers withhold on wages above $200,000.
- Utah has no municipal or county wage income tax, no state disability or family leave deduction, no employee unemployment deduction, and no reciprocity with any state. For supplemental pay such as bonuses and RSUs, use the Bonus Tax Calculator and RSU Tax Calculator.

How This Calculator Works
Hourly Mode: Gross Pay Per Period
Gross pay per period equals the hourly rate multiplied by hours worked per week, then scaled to the pay period. For biweekly pay: hourly rate × hours per week × 2. For weekly: hourly rate × hours per week. For semi-monthly and monthly: hourly rate × hours per week × (52 ÷ periods per year).
Salary Mode: Gross Pay Per Period
Gross pay per period equals annual salary divided by the number of pay periods per year. Weekly: ÷ 52. Biweekly: ÷ 26. Semi-monthly: ÷ 24. Monthly: ÷ 12.
Social Security Tax
Social Security is 6.2% of annualized gross wages up to the $176,100 wage base for 2025. The per-period amount is the annualized Social Security tax divided by pay periods. This calculator does not track year-to-date cumulative wages, so for workers approaching the wage base, actual withholding will stop mid-year once the limit is reached.
Medicare Tax
Standard Medicare is 1.45% on all gross wages. The calculator adds the 0.9% Additional Medicare Tax on annualized wages above $200,000, matching the employer withholding rule in IRS Topic 560: employers withhold the surtax once wages exceed $200,000 in a calendar year regardless of filing status. Your final liability on Form 8959 uses filing-status thresholds ($200,000 single/HOH, $250,000 MFJ, $125,000 MFS), so married filers may reconcile the difference at filing.
Federal Income Tax Withholding
The calculator follows IRS Publication 15-T Worksheet 1A (Percentage Method for Automated Payroll Systems) for 2025:
- Annualize the per-period gross pay (multiply by pay periods per year) - line 1c.
- Add Step 4a other income; subtract Step 4b additional deductions - lines 1d-1f.
- Subtract the line 1g allowance: $12,900 for married filing jointly or $8,600 otherwise. If the W-4 Step 2 box is checked, subtract $0 instead. The result is the Adjusted Annual Wage Amount (line 1i).
- Apply the Annual Percentage Method table for the W-4 filing status - the STANDARD schedule, or the Step 2 Checkbox schedule when the Step 2 box is checked - to get the tentative annual withholding (line 2g), then divide by pay periods (line 2h).
- Subtract Step 3 dependent credits divided by pay periods (line 3c).
- Add Step 4c extra withholding per period (line 4b).
Utah Income Tax Withholding
Utah withholds income tax using the method in the Utah State Tax Commission's Publication 14, Withholding Tax Guide. Unlike a graduated state, Utah applies a single flat rate to all wages and then subtracts a base allowance that works as a built-in low-income credit. The steps are:
- Annualize the per-period gross pay (multiply by pay periods per year).
- Multiply the annual wages by the flat 4.5 percent rate. This is the gross annual tax.
- Figure the base allowance. Start from the base allowance for your status ($450 single, $900 married for 2025), then subtract 1.3 percent of annual wages above the exemption threshold ($9,107 single, $18,213 married). The result cannot go below zero.
- Subtract the base allowance from the gross annual tax, divide by pay periods, and that is the per-period Utah withholding. If no federal W-4 is on file, the base allowance is zero and Utah withholds a flat 4.5 percent.
| Utah 2025 withholding input | Single | Married |
|---|---|---|
| Flat tax rate | 4.5% | 4.5% |
| Base allowance (annual) | $450 | $900 |
| Exemption threshold | $9,107 | $18,213 |
| Allowance reduction rate | 1.3% of excess | 1.3% of excess |
| Fully phased out above | ~$43,700 | ~$87,400 |
These are the 2025 Utah withholding figures, matching the Utah State Tax Commission Publication 14 schedules and the federal payroll-agency implementation of the same formula. Utah's Publication 14 also publishes eight per-frequency schedules (weekly through daily) that build the same base-allowance figures into each pay period; annualizing and dividing produces the same result. Your final Utah income tax is settled on Form TC-40, where the 4.5 percent flat rate and the Utah taxpayer tax credit apply. Because withholding is an estimate, small differences are reconciled at filing.
What Utah Does Not Deduct
Utah has no state disability insurance, no paid family leave payroll deduction, and no employee unemployment tax. Unemployment insurance is funded entirely by employers through the Utah Department of Workforce Services. There is also no local wage tax anywhere in Utah, so the only Utah line on a pay stub is the state income tax.
Real-World Paycheck Scenarios
Scenario 1: Single Worker Paid Biweekly
Ava earns $65,000 per year at a firm in Salt Lake City. She is paid biweekly, files single on her W-4, uses the single Utah status, and has a W-4 on file. Her biweekly gross is $65,000 ÷ 26 = $2,500.00.
Utah income tax detail (annualized): the gross annual tax is $65,000 × 4.5% = $2,925.00. The base allowance starts at $450 but is reduced by 1.3% of ($65,000 − $9,107) = $726.61, which is more than $450, so the allowance is zero. Utah withholding is $2,925.00 ÷ 26 = $112.50 per paycheck, an effective flat 4.5 percent. There are no disability, family leave, or unemployment lines, money a worker in California or Washington would see deducted.
Scenario 2: Lower-Income Worker Keeps the Base Allowance
Ben earns $30,000 per year at a shop in Ogden, paid biweekly, single, with a W-4 on file. His biweekly gross is $30,000 ÷ 26 = $1,153.85. At this income the base allowance is not fully phased out, so it lowers his Utah withholding below the flat rate.
Ben's base allowance is $450 − 1.3% × ($30,000 − $9,107) = $450 − $271.61 = $178.39. That credit lowers his annual Utah tax from $1,350 to $1,171.61, so he pays about $45 a paycheck instead of $51.92 at the flat rate. If Ben had no W-4 on file, Utah would withhold the full 4.5 percent with no base allowance, about $178 more per year.
Practitioner Insight
The Utah question we field most is why the state line looks like a flat percentage no matter what someone puts on their W-4. Utah does not use a per-allowance wage exemption the way many states do; it applies a flat 4.5 percent and then subtracts a fixed base allowance that acts as a low-income credit. For anyone above roughly $43,700 single or $87,400 married, that base allowance has already tapered to zero, so the Utah line is simply 4.5 percent of wages. We tell clients not to look for an allowance box to tune, because there is not one.
The second pattern is workers who have no W-4 on file, often after a job change. Utah keys its schedule to the federal W-4 marital status, and with no W-4 the employer withholds a flat 4.5 percent with no base allowance. For a lower earner that means giving up the base-allowance credit and over-withholding by up to a couple hundred dollars a year, which comes back as a refund. The fix is simply to file a current federal W-4.
The third thing we are flagging for 2026 is the rate cut. Utah lowered its income tax rate from 4.5 percent to 4.45 percent and nudged the base allowances up. It is a small change on a middle income, but it means the Utah line on a 2026 check is a little lower than the 2025 figure this calculator shows, and clients should not be surprised when the number ticks down.
When This Calculator Gives a Less Accurate Estimate
- Pre-tax deductions not entered: A 401(k) or 403(b) contribution and Section 125 medical premiums reduce the wages subject to both federal and Utah income tax withholding. This calculator does not model pre-tax deductions, so actual income tax withholding is lower and net pay is typically higher than the estimate.
- 2026 rate change: This calculator is labeled 2025 and uses the 2025 flat rate of 4.5 percent with the 2025 base allowances. For 2026 Utah lowered the rate to 4.45 percent and raised the base allowances (to $485 single / $970 married), so a 2026 paycheck withholds a little less. The Utah Payroll Taxes guide shows the 2026 figures.
- No federal W-4 on file: With no W-4, Utah withholds a flat 4.5 percent with no base allowance. Set the "Federal W-4 on File?" control to "No" to model that case.
- Per-frequency versus annualized method: Utah also publishes eight per-frequency schedules that round the base allowance to whole dollars for each pay period. Employers using those tables can differ by a few cents from the annualized computation this calculator uses; both are approved and reconcile on Form TC-40.
- Year-to-date Social Security cap: The calculator annualizes Social Security evenly. For a worker who passes the $176,100 wage base mid-year, actual Social Security withholding stops at that point rather than spreading across every paycheck.
- Supplemental wages: Bonuses, commissions, and other supplemental pay are withheld at Utah's flat rate along with regular wages. For the federal supplemental math on a bonus, use the Bonus Tax Calculator.
Frequently Asked Questions
How is take-home pay calculated in Utah?
Utah take-home pay equals gross pay minus federal income tax withholding, Social Security (6.2%), Medicare (1.45%), and Utah income tax withholding. Federal withholding uses IRS Publication 15-T. Utah income tax is withheld with the Utah State Tax Commission Publication 14 method: multiply annual wages by the flat 4.5 percent rate, then subtract a base allowance that is reduced by 1.3 percent of wages above the exemption threshold, using the single or married figures. Utah has no local wage income tax and no employee-paid disability, family leave, or unemployment contribution.
What is Utah's income tax withholding rate for 2025?
For 2025 Utah withholds a single flat rate of 4.5 percent on all taxable wages, then subtracts a base allowance that works as a low-income credit. The base allowance is $450 for single filers and $900 for married filers, and it shrinks by 1.3 percent of annual wages above $9,107 (single) or $18,213 (married) until it reaches zero. Above roughly $43,700 (single) or $87,400 (married) the allowance is fully phased out, so most full-time workers pay an effective flat 4.5 percent. For 2026 Utah lowered the rate to 4.45 percent.
How does the Utah base allowance work?
Utah does not use a per-allowance wage exemption. Instead its Publication 14 formula multiplies wages by 4.5 percent and then subtracts a fixed base allowance that acts as a built-in low-income tax credit ($450 single, $900 married for 2025). That base allowance is reduced by 1.3 percent of wages above the exemption threshold, so it phases out as income rises. A worker with no federal W-4 on file is withheld at the flat 4.5 percent with no base allowance.
Does Utah have a separate state W-4?
No. Utah has no separate state withholding certificate. The employer uses the marital status from your federal Form W-4: single, married filing separately, and head of household use Utah's single schedule, while married filing jointly uses the married schedule. There is no Utah allowance count to set. If no W-4 is on file, Utah withholds a flat 4.5 percent with no base allowance.
Does Utah have a local city income tax?
No. Utah has no municipal or county wage income tax withheld from employees anywhere in the state, including Salt Lake City, Provo, West Valley City, and Ogden. A Utah pay stub shows federal taxes and the state income tax, with no city or local wage line. This differs from states such as Ohio or Kentucky, where cities or counties layer a local income tax on top of the state tax.
Does Utah have income tax reciprocity with other states?
No. Utah has no reciprocal income tax agreements with any state. A resident of a neighboring state who works in Utah has Utah tax withheld and files a Utah nonresident return, then claims a credit for taxes paid to Utah on their home-state return so the same income is not taxed twice.
What is the Social Security wage base for 2025?
The Social Security wage base for 2025 is $176,100. Social Security tax at 6.2% applies to wages up to this amount, and withholding stops once cumulative wages exceed $176,100 for the year. Medicare has no wage base limit and continues at 1.45% on all wages. Employers withhold an additional 0.9% Medicare surtax on wages above $200,000 regardless of filing status; final liability thresholds are $250,000 for married filing jointly and $125,000 for married filing separately.
What To Do Next
If your Utah paycheck estimate looks off, first confirm you have a current federal Form W-4 on file with your employer and that the marital status matches what you intended, since Utah keys its withholding to that status, then check whether pre-tax benefit deductions (401k, health insurance) are lowering your taxable wages. If you are a lower earner with no W-4 on file, filing one restores the base-allowance credit. To see how your withholding connects to your year-end return, read the Utah Payroll Taxes guide and our How Payroll Taxes Work guide.
For hourly workers who also receive overtime, the Hourly Paycheck Calculator lets you model specific hours and frequencies. For a generic multi-state view, use the Paycheck Calculator. To understand every line item on your Utah pay stub, see our How to Read a Pay Stub guide.
If you have self-employment income in addition to wages, the 1099 Tax Calculator estimates your full federal tax burden including self-employment tax. If you need to estimate quarterly payments on that income, use the Quarterly Tax Calculator. To track a filed state or federal refund, use the Refund Tracker.
