Nigeria Tax Residency (183-day rule)

Key parameters
Threshold	183 days
Period / Window	Rolling 12 months
Counting	Any part of a day
Alternative	Domicile, permanent home, habitual abode, ties

You are a Nigerian tax resident for a year of assessment if you meet any one of six tests, in any order:

• Domicile — Nigeria is your domicile, regardless of where you spend the year.
• Permanent place — you have a permanent place available for your own domestic use in Nigeria. Availability is what counts, not whether you actually live in it.
• Habitual abode — you have a place of habitual abode in Nigeria, meaning somewhere you customarily stay.
• Economic and family ties — you have substantial economic ties and immediate family ties in Nigeria. The two are joined, so a business interest with no family in Nigeria, or family with no economic footing, is not this test on its own.
• 183-day presence — you stay in Nigeria for periods adding up to 183 days or more in a 12-month period.
• Nigerian diplomat abroad — you serve as a diplomat or diplomatic agent of Nigeria in another country.

The tests are written from both ends. You are a non-resident only if you fail every one of them at once, so staying under the day count settles nothing while a home, an abode or your family remain in Nigeria.

A resident individual is taxed in Nigeria on income, gains and profits wherever they arise, whether or not the money is brought into the country. A non-resident is taxed only on Nigerian-source income. These rules took effect at the start of 2026 and replaced a regime that had no explicit statutory definition of a resident individual.

• A permanent place you never use still counts. The test asks whether a place is available for your domestic use, so keeping an empty flat or a family house at your disposal can make you resident on its own.
• Family ties reach people living overseas. Substantial economic ties combined with immediate family in Nigeria can make a long-term expatriate resident despite spending almost no time in the country.
• An immigration permit is not tax residency. A residence or work permit governs your right to be in Nigeria, while the tax tests turn on domicile, a home, an abode, ties and days — decided entirely separately.

Tax left unpaid past its due date has a one-off 10% of the amount added to it, plus interest at the Central Bank of Nigeria's monetary policy rate with a spread set by the Minister. A demand for under-assessed tax normally has to be made within six years, but that limit falls away where the under-assessment came from a document or a statement found to be untrue. Professional tax advice is strongly recommended in situations like this.

A straightforward relocation

You take a job in Lagos in February and are in Nigeria for 300 days over the following twelve months, living in a rented flat there. You pass the 183-day test comfortably, and the permanent place available to you would make you resident anyway.

Just under, until the window moves

You work a rotation and count 176 days in Nigeria between January and December, with no home, family or business there. Measured over that window you are a non-resident. Shift the window to run from April instead, capturing an extra trip, and the same travel pattern takes you past 183 days.

Almost never there, still resident

You spend 40 days in Nigeria this year while working overseas, but your spouse and children live in your Lagos house and your main business income comes from a Nigerian company you own. The day count is nowhere near the threshold, yet substantial economic ties combined with immediate family in Nigeria make you resident.
