# Kentucky Tax Residence

Tax residency rule, United States. Page: https://usecountr.com/trackers/tax-us-ky-statutory/

## Summary

Kentucky treats you as a resident for income tax if your permanent home in law is somewhere else, but you maintain a place of abode in Kentucky and spend more than 183 days of the tax year in the state. Both parts are needed, and the days are added together across the year. A resident pays Kentucky tax on income from all sources. The rule is in section 141.010 of the Kentucky Revised Statutes and is applied by the Kentucky Department of Revenue.

- Limit: 183 days. Day 184 is the first day over the limit
- Period: The tax year, for most people 1 January to 31 December
- A day counts when: Not defined in the statute. Countr counts any part of a day
- Second condition: You maintain a place of abode in Kentucky
- Law: Kentucky Revised Statutes, KRS 141.010(32)
- Run by: Kentucky Department of Revenue

## Who it applies to

- People from Ohio, Indiana, Tennessee or another state who keep a flat or house in Kentucky for work.
- People who cross the state line to work in Kentucky and count on a reciprocity agreement to pay tax only at home.
- Owners of a second home in Kentucky who spend long seasons there.
- People in the horse, bourbon or car industries who come for long seasons each year.

## The rule

KRS 141.010(32) defines a resident in two ways. The first is an individual domiciled within Kentucky. The second is an individual who is not domiciled in Kentucky but maintains a place of abode in the state and spends in the aggregate more than 183 days of the taxable year in the state. 'In the aggregate' means that all days in the year are added together. The numbering of the definitions in KRS 141.010 has moved in recent amendments, the latest effective 15 July 2026, but the wording of the resident definition is the same.

Domicile is explained in the administrative regulation 103 KAR 17:010. It is the place where a person has established permanent residency. A domicile, once obtained, continues until a new one is acquired, and a change needs three things: an intent to change, an actual move, and a new abode. A move for a fixed period or for a side purpose does not change it.

The statute says 'place of abode' and does not add the word 'permanent' that many other states use. Neither the statute nor the regulation defines the term, and neither says how a part of a day is counted. This leaves room for judgement, and the Department looks at the whole situation.

The 183-day rule also matters for people who work across the state line. Kentucky has reciprocity agreements with Illinois, Indiana, Michigan, Ohio, Virginia, West Virginia and Wisconsin, under which wages are taxed by the state of residence. The Department's own form for these workers states that reciprocity does not apply to persons who live in Kentucky for more than 183 days during the tax year.

Why it exists: A state taxes residents on everything they earn and other people only on local income. If domicile were the only test, a person could live in Kentucky for most of the year, use its roads and services, and pay full tax only to a state that he or she rarely sees. The 183-day test, joined with a home in the state, catches the people who in practice live in Kentucky.

## Counting the days

You count the days of the tax year that you spent in Kentucky and add them together. The statute does not define a day, so the careful way is to count every calendar day on which you were in the state.

1. Take the tax year. For most people this is 1 January to 31 December.
2. Mark each calendar day on which you were in Kentucky, including the days you arrived and left.
3. Add up all marked days from every stay in the year.
4. Compare with 183. A total of 183 or fewer is not over the limit. A total of 184 or more meets the day condition.
5. Check the second condition: do you maintain a place of abode in Kentucky?
6. If you rely on a reciprocity agreement, check this count as well, because living in Kentucky for more than 183 days ends that protection.

How Countr counts it: Countr counts every calendar day on which your phone records you in Kentucky, from 1 January to 31 December, and compares the total with 183. Any part of a day counts as a full day. Countr starts to warn you 14 days before the limit. The app is simpler than the law in two ways. It cannot see whether you maintain a place of abode in Kentucky, so add this tracker only if you keep a home there. And it cannot tell a day when you only drove through from a day when you stayed, so it counts both. The warning can come early, never late.

## Examples

### The Louisville flat

Brian's family home is in Cincinnati, Ohio, and that is his domicile. His job is in Louisville, where he rents a flat and stays on work nights. In 2026 he is in Kentucky on 5 days of each week for 46 weeks, which is 230 days. He maintains a place of abode in Kentucky and has more than 183 days, so he is a Kentucky resident for 2026. The Ohio reciprocity agreement does not help him, because he lives in Kentucky for more than 183 days.

### One racing season in Lexington

Elena trains horses and is domiciled in Tennessee. She rents a house in Lexington from 1 April to 15 September 2026 and is in Kentucky every day of that period. That is 168 days. She has a place of abode in Kentucky, but she does not pass 183 days, so she is not a resident under this rule. Kentucky can still tax what she earns for work done in Kentucky.

### Exactly 183 days

Sam is domiciled in Georgia and keeps a flat in Covington. He is in Kentucky from 1 January to 2 July 2026 and then leaves. January to June has 181 days, and 2 more days in July make 183. The law says 'more than' 183, so he is not over the limit. One more day in Kentucky later in the year would be day 184 and would meet the day condition for all of 2026.

## Exceptions

- Without a place of abode in Kentucky, a person who is not domiciled there does not become a resident under this rule, whatever the number of days.
- Under 103 KAR 17:010, a member of the armed forces keeps the domicile he or she had when entering military service. Being stationed in Kentucky under orders does not by itself make a person from another state a Kentucky resident.
- A person who establishes or gives up Kentucky residency during the year is a part-year resident under KRS 141.010(27).
- If a person leaves Kentucky and returns within six months, 103 KAR 17:010 treats the departure as not permanent, and the person stays a resident or part-year resident for the time away.
- A person who was domiciled in Kentucky before moving abroad is presumed to still be a Kentucky resident, unless there is sufficient evidence that the Kentucky domicile was abandoned.
- Federal employees who are domiciled in Kentucky and work in another place are taxable as Kentucky residents.

## Common misconceptions

- "My state has a reciprocity agreement with Kentucky, so Kentucky can never tax my wages." Reciprocity is for people who live in one state and work in the other. The Department states that it does not apply to persons who live in Kentucky for more than 183 days during the tax year.
- "The 183 days must be one continuous stay." The statute says 'in the aggregate'. Every separate stay in the tax year is added to the total.
- "183 days alone makes me a Kentucky resident." The statute has two conditions for people domiciled elsewhere: a place of abode in Kentucky and more than 183 days. A person with no dwelling of any kind in the state does not meet the first one.
- "If I spend fewer than 183 days in Kentucky, I am not a resident." If Kentucky is your domicile, you are a resident with any number of days, even zero. The day count is only for people whose permanent home is in another state.

## Questions and answers

### Does a part of a day in Kentucky count as a day?

The Kentucky statute does not say. It only speaks of days spent in the state. The careful reading is to count any day on which you were in Kentucky, and Countr counts it that way.

### What happens if I go over 183 days in Kentucky by one day?

If you also maintain a place of abode in Kentucky, you are a resident for that tax year. Kentucky then taxes your income from all sources, and you file the resident return, Form 740. Your home state may give a credit for tax paid to Kentucky, or Kentucky for tax paid there.

### Is a rented room or a company flat a place of abode in Kentucky?

The statute does not define the term and does not ask for ownership. A dwelling that is kept for your use in Kentucky can be a place of abode. The Department decides on the facts.

### I live in Indiana and work in Kentucky every day. Am I a Kentucky resident?

Not for that reason alone. If you have no place of abode in Kentucky and go home to Indiana, you are not a resident under this rule, and the reciprocity agreement means that your wages are taxed by Indiana. This changes if you start to keep a home in Kentucky and live there for more than 183 days.

### Does the Kentucky day count start again each year?

Yes. The test looks at one taxable year. For most people the count goes back to zero on 1 January.

### Which Kentucky form does a part-year resident or nonresident file?

People who move into or out of Kentucky during the year, and full-year nonresidents with Kentucky income, file Form 740-NP. Residents of reciprocal states who only need a refund of tax withheld use Form 740-NP-R.
