Reciprocity state pair

Live in Ohio, work in Kentucky

Reciprocity agreement: covered employee wages are subject to state income tax only in your home state. Give your employer the work state's exemption form and arrange home-state withholding. County and city taxes require a separate check.

Before you use this estimate

This model assumes a full-year resident of Ohio, ordinary employee wages and all workdays physically in Kentucky. 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: An eligible OH resident who remains a Kentucky nonresident can claim the covered employee-wage exemption using the 2026 Kentucky K-4, reciprocal-state worksheet and box 4. Give the completed certificate to the Kentucky employer and keep a copy. Ohio shareholder-employees with a 20% or greater direct or indirect S-corporation interest do not qualify. Local occupational tax can still apply; check the actual workplace.

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 Ohio residence and Kentucky work
Step	Kentucky work state	Ohio home state
Tax before the modeled other-state credit	$0	$2,313
Modeled other-state credit subtracted	$0	$0
Tax after that credit	$0	$2,313

Total: $0 + $2,313 = $2,313 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.

Single filer, all wages earned in Kentucky, 2026 state tax rules, standard deductions. Local income taxes not included.

From paycheck withholding to your returns

Withholding: An eligible full-year Ohio resident gives Kentucky payroll the 2026 Form K-4, completing the reciprocal-state worksheet and box 4, to stop Kentucky state withholding on covered wages. The Ohio condition excludes a shareholder-employee who directly or indirectly owns 20% or more of the S corporation. Tell payroll when residence or exemption eligibility changes, and keep a copy of the certificate. Check Ohio withholding or estimates separately; the certificate does not stop local occupational withholding.
Returns: Report these wages on the Ohio resident IT 1040. If Kentucky state income tax was withheld in error and you qualify as a full-year reciprocal-state nonresident with Kentucky wages only, use Kentucky Form 740-NP-R to request the refund, with Schedule KW-2 and a copy of the Ohio return. The linked refund form is the 2025 edition; use the correct filing-year form. Other Kentucky income can require Form 740-NP instead, and local-tax refunds use separate procedures.
Credit or refund: For this eligible wage-only example, Kentucky state tax is exempt and Ohio taxes the resident wages. Recover erroneous Kentucky state withholding from Kentucky rather than treating it as an Ohio resident credit. Kentucky occupational taxes, Ohio municipal tax, school-district tax and any local credits are separate and excluded from this state-only comparison.

Worked example: $100,000 of wages

Single filer, full-year resident of Ohio, all work performed in Kentucky, no other income, standard deductions and modeled personal exemptions. Covered wages are exempt from Kentucky state income tax under wage reciprocity. Pay a modeled $2,313 to Ohio, total $2,313. This exemption is not an other-state tax credit.

For this $100,000 single-filer example, the modeled Ohio exemption is $1,900, leaving $98,100 of taxable nonbusiness income. The enacted 2026 formula is $332 + ($98,100 - $26,050) × 2.75% = $2,313.375 before rounding; eligible Kentucky state wage tax is $0. This excludes local taxes and special credits. The linked 2026 estimated-payment worksheet supports the exemption but still prints the older rate table; the 2026 rate here follows R.C. 5747.02(A)(3)(c), not that table.

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

This assumes full-year Ohio residence, no Kentucky residency and ordinary employee wages, not the 20%-or-greater S-corporation shareholder-employee exception. Keeping a Kentucky abode and spending more than 183 days there can defeat reciprocity. A move, business income, gambling winnings or Schedule K-1 income needs separate review. Kentucky local occupational taxes can remain due despite the state exemption; Ohio municipal and school-district taxes and local credits are excluded.

Official forms and instructions

Source audit 2026-10-20. 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.

Payroll certificate checked 2026-11-02. This scoped certificate correction does not change the annual-return source editions or the full workflow audit date above.

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.

Frequently asked questions

Do I pay Kentucky income tax if I live in Ohio?

If you qualify for the wage-reciprocity exemption, no Kentucky state income tax on covered employee wages: under reciprocity Ohio taxes them. City and county taxes require a separate check. An eligible OH resident who remains a Kentucky nonresident can claim the covered employee-wage exemption using the 2026 Kentucky K-4, reciprocal-state worksheet and box 4. Give the completed certificate to the Kentucky employer and keep a copy. Ohio shareholder-employees with a 20% or greater direct or indirect S-corporation interest do not qualify. Local occupational tax can still apply; check the actual workplace.

Do I have to file taxes in both Ohio and Kentucky?

Report these wages on the Ohio resident IT 1040. If Kentucky state income tax was withheld in error and you qualify as a full-year reciprocal-state nonresident with Kentucky wages only, use Kentucky Form 740-NP-R to request the refund, with Schedule KW-2 and a copy of the Ohio return. The linked refund form is the 2025 edition; use the correct filing-year form. Other Kentucky income can require Form 740-NP instead, and local-tax refunds use separate procedures.

Will I be taxed twice?

Not at the state level on covered wages: under reciprocity Ohio taxes them, about $2,313 on $100,000 in this model. The estimate includes resident county tax where modeled; other local taxes or credits are separate.
