Quick answer
Ohio: Estimate Ohio state withholding with confirmed local payroll selections from 1,441 local records, including municipalities, JEDD/JEDZ entries, and school districts. This calculator combines Ohio rules with federal withholding and FICA, while keeping work municipality, residence municipality, and school district choices explicit rather than assuming local withholding is zero.
How the Ohio 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. Ohio state withholding uses the selected pay period's percentage table after exemptions. Supported municipal, JEDD/JEDZ, and school-district amounts use the manually selected active Finder records. An entered preset deduction changes an Ohio wage base only when its official treatment is verified; otherwise WageFrame withholds the numeric estimate.
Example: For a biweekly entry, the Ohio biweekly exemption and percentage table apply. Local selections are not inferred from an address, and residence-municipality courtesy withholding is included only when requested. 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.
Why does Ohio need location selections? Ohio local withholding can depend on the work municipality or joint economic development district and the employee’s residence school district. Courtesy withholding for a residence municipality is calculated only when selected.
