How the Utah estimate works
Enter gross pay for one pay period, federal W-4 adjustments, and the state details shown above. Federal withholding follows Publication 15-T. Utah uses Publication 14 and the federal W-4 filing status: head of household follows the single schedule. Paychecks dated through May 31 use the 4.5% table, and paychecks dated June 1 or later use the revised 4.45% table.
Example: The paycheck date controls which official Publication 14 version is applied. Intermediate values are rounded to whole dollars where the Utah schedules direct that treatment. The calculator does not assume any unentered benefit deduction or invent a tax result.
Weekly, biweekly, semimonthly, and monthly are the supported paycheck frequencies. “Annual salary” is an earnings input and the annual view is a simple period multiplication; neither is an annual payroll-period method. The special Form W-4 adjustment for nonresident aliens is not modeled.
