Moving from Canada to Kentucky: State Tax, Local Tax, and Cross-Border Planning
Kentucky taxes personal income at a flat 4%, down from 5% after a phased cut that took full effect in 2024, with a statutory formula that can push the rate lower in future years if state revenue targets are met. On its own, that rate is competitive with Indiana and Pennsylvania and well below most of the country. For a Canadian moving to Louisville for the bourbon industry, UPS Worldport, or healthcare, or to Lexington and Georgetown for Toyota’s largest North American manufacturing plant or the University of Kentucky, the 4% headline looks straightforward. It isn’t the whole number. Many Kentucky cities and counties add an occupational license tax on top, and that local layer changes the real math more than the state rate suggests.
Kentucky’s state income tax is a flat 4%. On top of it, many cities and counties levy an occupational license tax, which functions as a local income tax in everything but name. Louisville Metro charges 2.2%, Lexington-Fayette charges 2.25%, and smaller cities generally run 1% to 2.5%. Kentucky also has one of the broadest reciprocity networks in the country, with seven neighboring states: Illinois, Indiana, Michigan, Ohio, Virginia, West Virginia, and Wisconsin. Kentucky starts from federal AGI, so the RRSP treaty deferral carries through unchanged, and the state excludes up to $31,110 of retirement income annually. No state estate tax, but an inheritance tax applies to non-lineal heirs.
How much does Kentucky actually tax?
Kentucky’s flat 4% sits below every Canadian province’s top marginal bracket, and below most provinces’ bottom bracket too.
| Jurisdiction | Rate | Notes |
|---|---|---|
| Ontario | ~20.5% (with surtax) | Top rate, on income above $220,000 |
| BC | 20.5% | Top rate, on income above $252,752 |
| Alberta | 15% | Top rate, on income above $355,845 |
| Quebec | 25.75% | Top rate, on income above $126,000 |
| Kentucky (state only) | 4% | Flat, applies to all income |
On $150,000 of employment income, Kentucky state tax alone runs about $6,000. Ontario provincial tax on the same income lands closer to $17,000 to $19,000 CAD before the federal comparison even enters the picture. That gap is a big part of why Louisville and Lexington pull Canadian manufacturing, healthcare, and logistics talent, but the local occupational tax below is what decides exactly how wide the gap stays once you pick an address.
What about local occupational license taxes?
Kentucky doesn’t run a statewide local income tax the way some states do, but cities and counties are free to levy their own occupational license tax, and most of the places Canadians actually move to have one. It’s generally tied to where the work happens rather than where you sleep, closer to Ohio’s model than Indiana’s county system. Louisville Metro charges 2.2%, Lexington-Fayette charges 2.25%, and many smaller cities and counties fall between 1% and 2.5%. Employers withhold it directly, and it’s typically reconciled without a separate multi-agency collection system like Ohio’s RITA or CCA network. Add Louisville’s 2.2% to the 4% state rate and the combined burden lands around 6.2%, still well under half of Ontario’s top bracket.
How does the reciprocity agreement work?
Kentucky has reciprocal agreements with seven states: Illinois, Indiana, Michigan, Ohio, Virginia, West Virginia, and Wisconsin, one of the broadest reciprocity networks of any state. Under reciprocity, a resident of one of those states who works in Kentucky pays income tax only to their home state, not to Kentucky, and vice versa. This mostly matters for people who settle near a state line, for instance living in Kentucky and commuting into Cincinnati, Ohio, or living just across the river in Indiana while working in Louisville. It doesn’t erase the local occupational license tax, which generally still applies based on work location regardless of reciprocity for state income tax.
How does Kentucky treat the RRSP and TFSA?
Kentucky starts from federal adjusted gross income and doesn’t add back RRSP items, so it inherits the treaty treatment resolved federally. The RRSP deferral under Article XVIII keeps internal growth out of federal AGI while deferred, and Kentucky follows that number through. Kentucky also excludes up to $31,110 of retirement income from state tax each year, a benefit that applies fully to government pensions and partially to private pension and retirement income, including RRSP distributions once they land in federal AGI as retirement income. TFSA income has no treaty protection and flows straight through to the Kentucky return once it hits federal AGI, which is why closing the TFSA before departure still applies here.
What happens on the Canadian side when I leave?
Leaving Canada for Kentucky triggers the same departure sequence as any Canada-to-US move:
- Deemed disposition at fair market value on worldwide property
- A final Canadian return covering January 1 through the departure date
- Provincial tax at your home province’s rates for the period you were still resident
- T1161 and, where the gain crosses the threshold, T1243
- Notifying the CRA of your change to non-resident status
- RRSP stays open and deferred; TFSA gets closed before departure
What other taxes matter in Kentucky?
- Sales tax: a flat 6% statewide, with limited local additions.
- Property tax: among the lower effective rates in the country, generally 0.8% to 1.0% of assessed value.
- Estate and inheritance tax: Kentucky repealed its estate tax. An inheritance tax remains, but spouses, parents, children, and siblings are exempt as Class A beneficiaries. More distant relatives (Class B) pay 4% to 16%, and unrelated heirs (Class C) pay 6% to 16%.
What should I do next?
The Canadian exit sequence is identical no matter which US state you’re headed to, so start with the departure checklist before you go. On the Kentucky side, confirm your city and county’s occupational license tax rate before signing a lease, since it moves the real number more than the state rate does.
