Kentucky / Wisconsin tax reciprocity
Each pair below is taxed by the RESIDENCE state, not the work state — the work state agrees not to withhold. Figures are illustrative, on a $75,000 salary.
Who taxes you, and what to file
The certificate goes to your employer in the state you work in. Figures are state income tax on $75,000, single, no dependents.
| Work in | Live in | Certificate to file | Tax under reciprocity | If the work state taxed you |
|---|---|---|---|---|
| Wisconsin | Kentucky | W-220 | $2,507 | $2,944 |
| Kentucky | Wisconsin | 42A809 | $2,944 | $2,507 |
The last column is hypothetical — what the work state would take with no agreement in place. It is not a second bill.
Does this cancel the local city or county tax?
Reciprocity is a state income tax concept. A local wage tax is a separate levy and can survive it.
- Working in Kentucky
- Kentucky local occupational license fees are not recoverable under reciprocity: Form 740-NP-R, the reciprocal-state refund return, instructs "Do not include local tax withheld." Kentucky publishes no explicit statement that local fees survive, so this rests on the refund return rather than a direct sentence.

Does reciprocity also cancel the local city or county tax?
Not necessarily — reciprocity is a state income tax concept, and a local wage tax is a separate levy that can survive it. Kentucky: Kentucky local occupational license fees are not recoverable under reciprocity: Form 740-NP-R, the reciprocal-state refund return, instructs "Do not include local tax withheld." Kentucky publishes no explicit statement that local fees survive, so this rests on the refund return rather than a direct sentence.
Does reciprocity cover self-employment or 1099 income?
No. Reciprocity covers employee compensation only, and the scope is set by each state's own materials rather than by a common rule — applies only to income earned as an employee — not to gains on sale of property, rents, lottery winnings, self-employment income or pass-through income. Self-employment income, rental income, gambling winnings and pass-through income are outside it, and may still require a nonresident return in the work state.
