Kenya Tax Residency (183-day and 122-day rules)

Key parameters
Threshold	183 days
Period / Window	Calendar year (1 Jan – 31 Dec)
Counting	Any part of a day
Alternative	122-day / year across 3 years, permanent home

Kenya applies 3 alternative tests, and meeting any one of them makes you resident:

• Permanent home plus presence — you have a permanent home in Kenya and were present there for any period at all during the year of income. A single day is enough once the home exists.
• 183-day rule — no permanent home in Kenya, but present for 183 days or more in that year of income.
• 122-day average — again with no permanent home in Kenya, present for periods averaging more than 122 days a year across that year and the 2 preceding ones.

The first test is the one that surprises people, because it collapses the day count entirely. A permanent home is not limited to property you own — a place continuously available to you for residential use can qualify — so keeping a house available in Kenya turns even a brief visit into residency.

The 122-day average works out at roughly 4 months a year sustained over 3 years. Like Kenya's other long-range test, it catches regular visitors who never approach the annual threshold in any single year.

• A permanent home makes a single day enough. Once a home is continuously available to you in Kenya, presence for any period in the year of income makes you resident, whatever the total.
• A permanent home need not be owned. A place continuously available for your residential use can qualify, so a long-term rental or a family house kept ready can trigger the test.
• The 122-day test is an average, not a floor. One year well above the line can carry 2 lighter years past the threshold, so the calculation has to be done across the 3 years together.
• Kenya taxes residents on worldwide employment income, which regularly catches people working remotely for foreign clients from a Kenyan base.
• Residency and immigration permits are separate. Holding a Kenyan work permit does not settle where you are taxed, and neither does having none.

Residents are taxed on worldwide employment income while nonresidents face a narrower charge on Kenyan-source income, so an incorrect position usually surfaces as foreign earnings left undeclared. The Kenya Revenue Authority charges a penalty on tax underpaid and adds late-payment interest accruing monthly on the outstanding balance, with a separate penalty for failing to file a return by the due date. Professional tax advice is strongly recommended in situations like this.

A house that decides it

You keep a family house in Nairobi, permanently furnished and available to you, and visit for 2 weeks in the year. The permanent home combined with any presence at all makes you a Kenyan tax resident despite the short stay.

Three years of regular visits

You spend roughly 130 days in Kenya each year for 3 consecutive years, with no home there. No year reaches 183, but the 3-year average passes 122 days a year, so the second test makes you resident.

A single long contract

You take an 8-month posting in Mombasa within one calendar year and stay in hotels throughout. That is around 240 days with no permanent home, so the 183-day test makes you resident for that year of income.
