The 2026 tax change that catches almost every returnee

If your understanding of Nigerian tax residency was formed before this year, it is out of date, and the direction of the change is not favourable.

This is the single most expensive thing on this site to get wrong quietly.

What changed

The old test hinged largely on physical presence. Fewer than 183 days in the country and most diaspora treated themselves, reasonably, as non-resident. It was a workaround that worked and everybody used it.

The 2025 Nigeria Tax Act, effective from 1 January 2026, moved the test away from counting days and towards the depth of your connection to Nigeria.

You can now be treated as tax resident if any one of the following is true:

• Nigeria is your domicile, meaning your permanent home and the centre of your interests
• You have a permanent abode available to you here for your personal use
• You habitually stay here
• You have substantial ties, meaning a spouse, parents or children here, or significant business interests
• You spend 183 days or more here in a twelve month period
• You are a Nigerian diplomatic agent abroad

Read the second and fourth points again.

A flat in Lagos that sits empty waiting for your visits is a permanent abode available for your personal use. Children living here is a substantial family tie. A stake in the family business is a substantial economic tie.

None of those require you to set foot in the country for 183 days.

Why it matters

Because residents are taxable on income earned, accrued or derived anywhere in the world. Not merely income with a Nigerian source.

Non-residents remain taxable only on Nigerian-source income. The distinction between the two categories has always mattered. What changed is how easily you fall on the resident side of it.

So the diaspora professional who kept a flat in Ikoyi, visits twice a year, and has never given Nigerian tax a second thought because their salary is paid in London, is now in a position that needs actual advice rather than an assumption.

The half nobody mentions

Leaving your current country does not automatically end its claim on you either.

The United States taxes its citizens and permanent residents on worldwide income regardless of where they live. Moving does not change that, though foreign earned income exclusions and foreign tax credits exist to reduce double payment.

The United Kingdom applies a statutory residence test that looks at days, ties and work patterns, and can split a tax year.

Canada looks at residential ties rather than a simple day count, and applies a departure charge on becoming non-resident that catches people who did not plan for it.

It is entirely possible to be treated as resident in two countries simultaneously. Double taxation treaties exist precisely to allocate who taxes what in that situation, and applying one correctly is not something to improvise from a forum post.

What to actually do

Before you move, not after:

1. Establish where you are resident now, and what your current country requires when you leave. The departure position is often the expensive part and it is time-sensitive.
2. Work out whether your existing Nigerian ties already make you resident here, independent of the move. For many people reading this the answer is yes, and has been since January.
3. Get the two analysed together by one professional who does cross-border work, rather than by two accountants who each understand one side.
4. Ask specifically about the treaty position between Nigeria and your current country, and about which income streams sit where.
5. Sort the structure before you generate the income, not in the following April. Almost everything useful here is a planning exercise, and almost nothing is fixable retrospectively.

Who this hits hardest

Remote workers keeping a foreign salary. Your income is now potentially visible to two tax authorities. See the remote work piece for the employment side.

Anyone with property here. The permanent abode limb is the one people trip over without moving at all.

Anyone with a family business stake, however passive it feels.

People planning a partial return, the six months here and six months there arrangement. That used to be the clean answer. It is now the one most likely to make you resident in both places at once.

The uncomfortable truth

A meaningful number of people reading this were already caught by this change in January and do not know it.

That is not a reason to panic, and it is certainly not a reason to avoid coming back. It is a reason to have one paid conversation with someone qualified, early, with your real numbers in front of them.

The fee will be a fraction of the cost of finding out later.

Nothing here is tax advice and it cannot be, because the answer depends entirely on facts specific to you. This is a summary of a rule change so you know what to ask. Verify current rules and get professional advice before acting. Position as at September 2026.
