Limitations
Enter gross pay for one pay period, federal W-4 adjustments, and the state details shown above. Federal withholding follows Publication 15-T. Kentucky annualizes current wages, subtracts the official 2026 standard deduction, applies the 3.5% state rate, returns the amount to the pay period, and adds any employee-requested amount. Local occupational taxes are not calculated.
Example: A Kentucky result includes the state line but is always marked partial. County, city, and special-district occupational taxes are named as omitted rather than assumed to be zero. 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.
