How the Virginia 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. Virginia annualizes wages, applies the exact-method subtraction for Form VA-4 personal, dependent, age, and blindness exemptions, calculates tax from the published brackets, rounds the annual tax as directed, and returns it to the selected pay period.
Example: VA-4 exemption counts remain independent from the federal W-4. Enter both exemption lines exactly as shown on the state certificate. 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.
