Reciprocity state pair

Live in Kentucky, work in Ohio

Payroll starting point: Ohio IT 4, Section III (opens in new tab). Use the current combined IT 4 already linked here, select the Kentucky-resident reciprocity waiver and give it to payroll. Arrange Kentucky payments and separately check the actual Ohio work municipality; a Kentucky home does not create Ohio school-district residence.

Before you use this estimate

This model assumes a full-year resident of Kentucky, ordinary employee wages and all workdays physically in Ohio. Check exemption eligibility before treating a work-state amount of $0 as your own result. Withholding is a prepayment, not final tax liability. Other income, a move during the year, remote work and separate local taxes or credits can change the result.

Wage-exemption conditions: KY residents working in OH are exempt from Ohio state tax on covered wages; give the employer the current combined Form IT 4, selecting the reciprocity exemption in Section III. The combined form replaced IT 4NR. Special rules for 20%+ pass-through-entity owner compensation and Ohio municipal taxes require a separate check.

This pair's wage-exemption or credit guidance checked 2026-10-14. Individual return calculations and other source dates are separate.

Typical state returns

This is the usual filing pattern, not a determination that you must file. Filing thresholds, age or dependent status, other income and withholding refunds can change which returns you need.

How this $100,000 estimate adds up

These steps follow the selected home, work state, salary and filing status. They reconcile the model's annual liability, not the amounts withheld from your paycheck.

Modeled state income tax for Kentucky residence and Ohio work
Step	Ohio work state	Kentucky home state
Tax before the modeled other-state credit	$0	$3,382
Modeled other-state credit subtracted	$0	$0
Tax after that credit	$0	$3,382

Total: $0 + $3,382 = $3,382 a year. Amounts are rounded for display. Work-state wage exemptions, when applicable, are already reflected in the first row; they are not an other-state credit.

No other-state credit is subtracted in this selected scenario. Included county components stay in these amounts; excluded local taxes and credits stay excluded. Federal income tax, payroll programs and refund eligibility are outside this reconciliation.

From paycheck withholding to your returns

Withholding: Give Ohio payroll the combined IT 4, completing the applicable personal information, Section III reciprocity waiver for a full-year Kentucky resident, and signature. The employer keeps it; it is not sent to Ohio Taxation. This form replaces the former IT 4NR. Ask payroll to withhold Kentucky income tax instead. If Kentucky withholding is unavailable or insufficient, use Kentucky's 2026 estimated-payment instructions and 740-ES requirements. Ohio municipal withholding is a separate matter.
Returns: File Kentucky resident Form 740 when the filing requirements are met. A full-year Kentucky resident whose only Ohio-source income is covered wages generally does not need an Ohio state return unless seeking a refund. If Ohio state tax was withheld, file Ohio IT 1040 with the reciprocity-wage deduction and Schedule of Ohio Withholding, using the required W-2 evidence. The published 2025 instructions put the deduction on Schedule of Adjustments line 14; use the year's actual form. Other Ohio income can require filing. Handle municipal tax and any school-district withholding separately from the Ohio state refund.
Credit or refund: Covered wages belong to Kentucky for state income-tax purposes. Recover erroneous Ohio state withholding from Ohio rather than using a Kentucky other-state credit for tax that is not owed. State reciprocity does not decide municipal tax or any separate local credit.

Worked example: $100,000 of wages

Single filer, full-year resident of Kentucky, all work performed in Ohio, no other income, standard deductions and modeled personal exemptions. Covered wages are exempt from Ohio state income tax under wage reciprocity. Pay a modeled $3,382 to Kentucky, total $3,382. This exemption is not an other-state tax credit.

Annual liability, not paycheck withholding or a refund estimate. Federal tax, payroll programs, other local taxes, special credits and part-year residency are excluded. Local income taxes not included.

Remote-work and local exceptions

Full-year Kentucky resident, ordinary W-2 wages, all workdays physically in Ohio. The Ohio reciprocity deduction does not cover business, rental, gambling or other nonemployee income; compensation from a pass-through entity in which you own at least 20% is also excepted. The calculator excludes Ohio municipal and Kentucky local taxes and does not allocate hybrid workdays.

Covington home, work inside Cincinnati city limits

A full-year Covington, Kentucky resident working physically inside Cincinnati can qualify for the Ohio state-wage exemption while still owing Cincinnati income tax. Cincinnati says a nonresident with city-earned compensation and no city withholding must file; fully withheld wages generally do not require a city return. Keep the actual workplace address, W-2 local boxes and pay statements. An Ohio work location alone does not make this Kentucky resident liable for an Ohio school-district income tax, which follows Ohio school-district residence.

Official forms and instructions

Source audit 2026-11-01. Use the return and instructions for the year you are filing; a current-forms link may still show a prior-year return. Official sources checked; not independently reviewed.

Check your payslip and keep these records

Compare the payroll certificate you supplied with the state withholding on your next payslip. Check city, county and school-district entries separately; a state exemption does not settle local tax.
Keep your W-2 and other withholding statements, copies of payroll certificates, filed state and local returns, and proof of tax paid. A refund depends on actual withholding and the completed return, not this annual estimate.
Keep an actual work-location log, including home-working days. This calculator assumes ordinary employee wages, full-year residence in Kentucky and every workday physically in Ohio.
If you moved during the year, have nonwage income or do not meet that scope, follow the pair's remote and local exceptions and the moving-year tax guide before using the amount as your own result. This tool does not calculate hybrid allocation, local credits or a personal refund.

What to do

Keep a record of the days you work in each state, especially if you sometimes work from home.

Local income taxes

Ohio: ~600+ municipalities levy income tax on wages at work location (commonly 1-2.5%; e.g., Columbus 2.5%, Cleveland 2.5%, Cincinnati 1.8%), regardless of state reciprocity. Residence city may also tax, with a full/partial/no credit for work-city tax depending on the city. An eligible 20-day occasional-entrant withholding exception can apply to work in another municipality; the principal work location and certain long-term worksites can require withholding from the first day. Small-employer and other rules may differ. Check with payroll and the municipality. Many school districts also levy a resident-only income tax.
Kentucky: City/county occupational license taxes are levied by work location on residents and nonresidents alike (e.g., Louisville Metro ~2.2% combined, Lexington 2.25%), and are NOT covered by KY's state reciprocity agreements - OH/IN commuters into Louisville/Covington still pay them.
