Under Section 2 of Kenya's Income Tax Act, Cap. 470, you are a tax resident for a given year of income — the calendar year, 1 January to 31 December — if you have no permanent home in Kenya but are present for periods amounting in aggregate to 183 days or more in that year. The count is aggregate physical presence, and it resets each 1 January. Two other routes can make you resident even below 183 days: holding a permanent home in Kenya plus any presence that year, or being present in the year and each of the two before it while averaging more than 122 days a year. Bounded's counter tracks the 183-day calendar-year threshold; the permanent-home and 122-day tests are explained below.

Who it applies to

The 183-day day count matters most if you are:

• A remote worker, contractor, or expat spending long stretches in Kenya without a settled home there.
• A frequent business traveler whose trips, added up over a calendar year, approach 183 days.
• A member of the Kenyan diaspora dividing the year between Kenya and abroad.

The test is about physical presence, not nationality — Kenyan citizens and foreigners are counted the same way. Note that the permanent-home and three-year-average routes can pull in people who never reach 183 days in any single year, so the day count alone does not settle your status (see below).

The rule — and why it exists

Section 2 (Interpretation) of Cap. 470 defines an individual as "resident" in a year of income if any one of three tests is met:

• (a) Permanent home. You have a permanent home in Kenya and were present in Kenya for any period during that year of income.
• (b) The 183-day test. You have no permanent home in Kenya but were present for a period or periods amounting in the aggregate to 183 days or more in that year of income.
• (c) The three-year average. You were present in Kenya in that year of income and in each of the two preceding years, for periods averaging more than 122 days in each year.

The day count in limb (b) applies, strictly read, only to people without a permanent home in Kenya — because anyone with a permanent home is already caught by limb (a). In practice, most people who spend 183+ days in Kenya also have a home there, so 183 days is a reliable trigger. But the reverse is the trap: staying under 183 does not clear you if limb (a) or (c) applies.

Why it exists: countries treat sustained physical presence, a settled home, or a repeated pattern of long stays as signs that your economic life is rooted in the country. Kenya's three limbs each capture one of those signals, so residency is not something a person can dodge purely by counting to 182.

Counting the days

For the 183-day test, you add up every day you are physically present in Kenya during the calendar year. Days need not be consecutive — the statute counts "a period or periods amounting in the aggregate to 183 days."

1. 1Count every day you are physically present in Kenya between 1 January and 31 December.
2. 2Separate trips are added together — the days do not need to be consecutive.
3. 3You are resident under this limb once the aggregate reaches 183 days or more in that calendar year.
4. 4The count resets to zero on 1 January — each year of income stands on its own.

One honest caveat: Cap. 470 and published KRA guidance do not define a midnight rule or say how partial arrival and departure days are treated. The common, conservative practice is to count any day on which you set foot in Kenya as a full day present. Bounded's counter uses that convention, but treat it as a sensible default rather than a codified legal rule.

The 122-day three-year test

Limb (c) is a distinct test that Bounded's day counter does not model on its own — it spans three calendar years at once and depends on presence in every one of them, which a single-year counter cannot represent faithfully. It is important to understand by hand:

• Three years, all three required. You must be present in Kenya in the current year of income and in each of the two preceding years. If you were absent for a whole year in that window, limb (c) cannot apply.
• The average is over 122 — strictly. Your presence must average more than 122 days per year across those three years. Exactly 122 is not enough. As a rough total, "more than 122 on average" means more than 366 days across the three years combined (367+), provided you were actually present in each year.
• It catches the sub-183 frequent visitor. Someone who spends, say, 150 days in Kenya every year never trips the 183-day test, but comfortably clears the 122-day average — and is resident under limb (c).

Because this limb turns on a per-year presence requirement and calendar-year alignment, a simple "days in the last three years" total would give the wrong answer in edge cases (for example, if you missed a whole year). If your yearly presence sits in the 120–180 range and recurs, run this test manually — it is the one most people overlook.

Examples

Example 1 — resident by the 183-day count

Amina is a consultant with no settled home in Kenya. In 2026 she is present for 90 days in the first half of the year and 100 more in the second half — 190 days in aggregate. She passes 183 within the calendar year, so she is a Kenyan tax resident for the 2026 year of income under limb (b).

Example 2 — under 183, but caught by the permanent home

David keeps a house in Nairobi that is always available to him. In 2026 he visits for just 40 days on business. He never approaches 183 days, but because he has a permanent home in Kenya and was present during the year, he is resident under limb (a) — the day count is irrelevant here.

Example 3 — the three-year average catches a frequent visitor

Grace spends roughly 150 days in Kenya each year — 150 in 2024, 148 in 2025, and 152 in 2026 — with no permanent home there. No single year reaches 183, so limb (b) never triggers. But she was present in all three years and her average is about 150 days, well over 122, so she is resident for 2026 under limb (c).

Exceptions & edge cases

• Permanent home overrides the count. Under limb (a), a permanent home in Kenya plus any presence during the year makes you resident with no 183-day count. Since the Finance Act 2022, a "permanent home" can be found where you reside, where a home is available to you, or where the Commissioner considers your personal or economic interests to be closest.
• Calendar year, no rolling reset trick. The year of income is fixed at 1 January to 31 December. Unlike a rolling-12-month regime, splitting a stay across a year-end can keep you under 183 in both years — but watch the three-year average, which can still catch a recurring pattern.
• The 122-day test is genuinely tri-year. It needs actual presence in each of the three years and a strict "more than 122" average. A single missed year breaks it, and 122 exactly does not qualify.
• Counting convention is uncodified. No midnight or part-day rule appears in Cap. 470 or KRA guidance. Where a day is borderline, the safe assumption is to count it.
• Double-taxation treaties. If you are resident in Kenya and another country at once, the relevant treaty tie-breaker (permanent home → centre of vital interests → habitual abode → nationality) assigns a single treaty residence and divides taxing rights.

The permanent-home limb is a facts-and-circumstances judgment rather than a day count, and treaty positions turn on your specific situation — those are the points where speaking to a Kenyan tax adviser genuinely earns its keep. The three day-based mechanics themselves, though, you can track yourself.

Common misconceptions

• "Under 183 days means I'm definitely not resident." False — a permanent home plus any presence (limb a), or a three-year average over 122 days (limb c), can make you resident well below 183.
• "The count rolls over 12 months." No — Kenya uses the calendar year of income, and the 183-day count resets on 1 January.
• "122 days a year is fine." Not necessarily — the three-year test triggers at more than 122 on average, and exactly 122 is the borderline that stays out, but a whisker over it (with presence in all three years) makes you resident.
• "Arrival and departure days don't count." There is no rule saying so — the statute counts aggregate days present, so the conservative approach is to count any day you are physically in Kenya.
• "The 183-day test applies to everyone." Read strictly, limb (b) applies to people without a permanent home in Kenya; those with a home are already caught by limb (a) at any level of presence.
