How the Arkansas 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. Arkansas normally annualizes the paycheck, subtracts the $2,470 standard deduction, applies the 2026 formula brackets and $29 annual credits for AR4EC exemptions, then returns the rounded annual tax to the pay period. When the employee confirms the AR4EC low-income election, the calculator uses the exact filing-status, dependent, frequency, and wage interval from the official 22-page tables instead.
Example: The official formula example uses $2,127 monthly pay and two AR4EC exemptions. It produces $496 of rounded annual gross tax, subtracts $58 of credits, and returns $36.50 of monthly Arkansas withholding. 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.
