Basis

Kentucky treats you as a resident for income tax if you are not domiciled there but maintain a place of abode in Kentucky and spend more than 183 days of the taxable year in the state. Meet both and Kentucky taxes all of your income for that year; day 184 is the trigger. Separately, anyone domiciled in Kentucky is a resident regardless of days.

Who it applies to

This matters most if you are:

• A remote worker or frequent traveler spending long stretches in Kentucky across a year.
• Someone who keeps a house or apartment in Kentucky while living or working elsewhere.
• A person moving into or out of Kentucky mid-year, whose days pile up on one side of the move.
• A commuter living in a neighboring state and working in Kentucky, where reciprocity may apply.

It applies to individuals based on physical presence and available housing — not on where you vote, work, or hold a driver's license, although those can be evidence of domicile.

The rule — and why it exists

KRS 141.010 defines "resident" as “an individual domiciled within this state or an individual who is not domiciled in this state, but maintains a place of abode in this state and spends in the aggregate more than one hundred eighty-three (183) days of the taxable year in this state”. That gives two routes:

• Statutory residency (the 183-day test). A place of abode in Kentucky plus more than 183 days in the state during the taxable year makes a non-domiciliary a resident for that year.
• Domicile. If Kentucky is your true, fixed, permanent home — the place you intend to return to — you are a resident regardless of the day count.

What the wording means: the statute says "place of abode", without the "permanent" qualifier that New York or Connecticut use. A second home or a rented apartment you keep in Kentucky can satisfy the abode condition, so the day count is usually the deciding factor.

Counting the days

1. 1Count each day you are in Kentucky during the taxable year (for most people, 1 January to 31 December). Days are aggregated across separate visits.
2. 2The count resets at the start of each new taxable year — it is a fresh annual tally, not a rolling window.
3. 3Kentucky does not define a partial day, so count arrival and departure days as Kentucky days to be safe.
4. 4You become a statutory resident once you exceed 183 days while also maintaining a place of abode in the state.

Because the window is the taxable year, a stay split across a year-end can leave you under the threshold in each individual year even if the trip itself is longer.

Examples

Example 1 — clearly a statutory resident

You rent a house in Louisville and are in Kentucky for about 210 days across the year. Because you exceed 183 days and maintain a place of abode, you are a statutory resident and Kentucky taxes all of your income for that year.

Example 2 — over 183 days but no abode

You spend 200 days in Kentucky staying in short-term hotels for a temporary project, keeping no dwelling of your own. The day count is exceeded, but with no place of abode that you maintain the statutory-residency test is not met on these facts (a separate domicile analysis could still apply).

Example 3 — a stay across year-end

You keep a Kentucky home and are present from 1 October to 30 April — about seven continuous months. Split by taxable year, that is 92 days in the first year and 120 in the second (121 in a leap year), so neither year alone exceeds 183 and statutory residency is not triggered by the day count.

Exceptions & edge cases

• Domicile overrides the day count. If Kentucky is your permanent home, you are a resident even with 183 or fewer days.
• "Place of abode", not "permanent". Do not assume a second home or a long rental falls outside the rule because it is not your main residence.
• Part-year moves. Moving into or out of Kentucky mid-year can create part-year residency, with income allocated between resident and nonresident periods.
• Reciprocity with neighboring states. Under 103 KAR 17:140, Kentucky has reciprocal agreements with Illinois, Indiana, Michigan, Ohio, Virginia, West Virginia and Wisconsin, generally exempting residents of those states from Kentucky tax on wages earned in Kentucky — subject to each agreement's conditions, such as daily commuting for Virginia. The Department of Revenue's Form 740-NP-R adds that reciprocity does not apply to anyone who lives in Kentucky for more than 183 days in the tax year.
• Returning within six months. Under 103 KAR 17:010, if you move out of Kentucky and return within six months, the move is treated as not intended to be permanent, and you are considered a resident (or part-year resident) for the time your abode was elsewhere.

Common misconceptions

• "183 days or fewer means I'm safe." Not if Kentucky is your domicile — the domicile test can make you a resident below the threshold.
• "Days alone make me a statutory resident." The 183-day test also requires a place of abode in the state; both conditions must be met in the same year.
• "Only Kentucky income is taxed." A resident is taxed on all income for the year, wherever it is earned.
• "It has to be one unbroken trip." The count is a total of all days present in the taxable year, not a single continuous stay.
