What counts as taxable foreign income in Nigeria?

The rules changed on 1 January 2026, when the Nigeria Tax Act 2025 took effect. Nigerian residents are now taxed on worldwide income, and the Act widened who counts as a resident. For the wider picture of what changed across Nigerian money rules this year, see Nigeria's money rules in 2026. This article explains what the rules say. It isn't tax advice, and if the amounts are real you want an accountant looking at your own numbers.

Who counts as a Nigerian tax resident?

Six separate tests make you a Nigerian tax resident, and you only need to meet one of them. The best known is spending 183 days or more in Nigeria in any 12-month period, counting temporary absences. The other five catch people who spend far less time in the country than that.

You're non-resident only if every one of those is false at the same time, which is the part most people reading about the 183-day rule miss. Being out of Nigeria for most of the year doesn't settle it on its own, because a home or a family in Lagos can make you resident on a different test. PwC's summary of the residence rules sets out all six.

One warning is worth having before you rely on any of this. Zenith Bank's guidance for Nigerians in the diaspora says residency rests solely on the 183-day physical presence rule, while PwC's summary lists all six tests. On those two readings the same person, out of the country for 200 days but with a flat and a family in Lagos, is non-resident on one and resident on the other. If that's close to your own situation, get it confirmed in writing before you decide you owe nothing.

Does your foreign income count if the money never enters Nigeria?

Yes. If you're a Nigerian tax resident, your income is taxed in Nigeria wherever it arises and whether or not you bring it into the country. PwC's summary of the rules puts it plainly: a resident's income, gains or profits are treated as Nigerian income, wherever they arise and whether or not they're brought into Nigeria.

What that does to your money is straightforward. Leaving dollars sitting in a US account, or in a dollar balance you never convert, doesn't put them outside Nigerian tax. The tax follows the income, not the transfer. A freelancer who invoiced $30,000 over the year and converted none of it has the same declaration to make as one who moved every dollar into naira the week it landed.

The reverse is worth knowing too, because the worry runs both ways. Money arriving in a Nigerian account isn't automatically taxable income. Zenith Bank's diaspora guidance says payment into a Nigerian account does not by itself make income taxable, and that a non-resident's earnings from work done entirely outside Nigeria stay exempt even when the funds are transferred in. A non-resident sending money home and a resident declaring a dollar invoice are two different situations, and they get two different answers.

What kinds of foreign income are taxable?

If you're resident, the list is wide. Freelance and contract fees from clients abroad, salary from a foreign employer, platform payouts from Upwork, Fiverr or a creator programme, consultancy fees, and income from property or investments held outside Nigeria all count. Nobody withholds the tax for you, so you work it out and declare it yourself.

• Freelance and contract fees: money from a client abroad for work you did, whether it came through a platform or straight into your account.
• A salary from a foreign employer: a remote job for a company with no Nigerian entity. No PAYE is deducted at source, so the whole amount is yours to declare.
• Platform payouts: Upwork, Fiverr, Deel, YouTube, AdSense, app store revenue, sponsorships and brand deals.
• Income from assets held abroad: rent on a foreign property, dividends on foreign shares, interest on a foreign balance.
• Business profits: if you run the trade from Nigeria, the profits are Nigerian profits even when every customer is abroad.

Gains on foreign investments follow their own rules rather than these ones, and they're the part most often got wrong. If you sell US shares, see whether Nigerians pay tax on US stock gains, which covers why the exemption on Nigerian company shares doesn't reach foreign ones.

What foreign money isn't taxable income?

Some money that arrives from abroad isn't income at all. A gift from a relative, money sent home to support a household, and a repayment of a loan you made are all transfers rather than earnings. A non-resident's earnings from work done entirely outside Nigeria also stay exempt, even when the money is transferred into a Nigerian account.

That last one rests entirely on being non-resident, so it's worth going back through the six tests before you count on it. A Nigerian who works remotely for a foreign employer, spends most of the year abroad, and still keeps a home and a family in Nigeria is in exactly the position where the exemption looks like it applies and may not. The money being for work done abroad isn't on its own enough.

How much tax do you pay on foreign income in Nigeria?

The first ₦800,000 of your total annual income is tax-free, and above that the rate rises in steps with income to a top rate of 25%. Foreign income isn't taxed on a separate scale. It's added to everything else you earned that year, so a Nigerian salary and a dollar freelance income are assessed together.

Take the band widths themselves from a current source rather than from an article. Published versions of the new table disagree about where the upper bands start, and calculating on the wrong one gives you the wrong number. The tax-free ₦800,000 and the 25% ceiling are the two figures they all agree on, so those are the two used here. Your own band depends on your total income for the year, which is a figure only you have.

One more thing decides the number, and it's the rate you convert at. Foreign earnings are declared in naira at the official rate published by the Central Bank, not at the black market rate, also called the parallel market rate, and not at whatever rate your app gave you on the day. The black market rate is the higher of the two, so using it inflates your declared income and the bill that comes with it.

Where does Daya Borders fit?

Daya Borders is the account the foreign income lands in, and for tax what matters is the record it leaves. Daya Borders takes 0% on incoming dollars and euros with no cap, so the amount your client sent is the amount on your statement, and that's the figure you declare. The account and routing details are in your own name.

Daya Borders also lets what arrives stay in the currency it arrived in, dollars or euros, until you choose to convert it. Worth being clear about one thing there, because it's the most common mistake on this subject: holding the dollars doesn't delay the tax. The income was taxable when you earned it, not when you converted it. Holding changes the rate you eventually get, and it changes nothing about whether the income is declarable.

Where Daya Borders doesn't help is the declaration itself. It isn't an accounting tool, it won't file anything for you, and it can't tell you which band you're in. If your foreign income is large, or it comes from several countries, an accountant is worth more to you than any app. What the account gives you is a clean record of what arrived and when, which is the thing you'll be asked for.

Do you pay Nigerian tax again if you already paid tax abroad?

You shouldn't pay twice over, though the relief isn't automatic and you have to claim it. Nigeria has double taxation treaties with 15 countries, including the UK, Canada, China and South Africa. Where a treaty applies, one country taxes first and the other gives you a credit for it. Where there's no treaty, Nigerian law still gives unilateral relief.

The United States is the one that catches Nigerian freelancers out, because Nigeria has no tax treaty with it. A US client or platform that withholds tax at source, as Amazon does on KDP royalties paid to Nigerian authors, leaves you claiming unilateral relief with your own documentation rather than leaning on a treaty rate. Keep every withholding statement a foreign payer sends you, because that paperwork is what the claim rests on.

What records should you keep?

Keep your records for at least six years, because that's how far back the Nigeria Revenue Service can audit. For foreign income the useful set is small: the invoice, the contract or platform agreement, the statement showing what landed and when, the rate you converted at, and any withholding certificate from a foreign payer.

Keeping them matters more than it used to, because dollar inflows tied to a bank verification number are visible to the tax authority whether or not you file. The records are what let you show that a transfer was a gift rather than a fee, or that tax was already deducted abroad, at the point when somebody asks.

What happens if you don't declare it?

Failing to register or to file carries a penalty that starts in the first month and adds more for every further month it goes unfixed, and unpaid tax carries interest on top. A false declaration is treated more seriously again, with fines and, at the far end, imprisonment. None of that depends on how the money reached you.

If you've read this far and think it applies to you, the practical sequence is short:

1. Work out whether you're resident, on any one of the six tests rather than on the 183 days alone.
2. Add your foreign income for the year to everything else you earned, converted into naira at the official rate.
3. Get a Tax ID if you don't have one, and register with your state tax authority if you're self-employed.
4. File your annual return, declaring the worldwide figure rather than only what you brought in.
5. If the amounts are large or they come from more than one country, pay an accountant to check it.
