AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
You generally pay income tax where you are tax resident. If you are not Nigerian resident, Nigeria taxes only Nigerian-source income, and the NiDCOM diaspora guide states that services physically performed outside Nigeria are not taxable in Nigeria. Nigerian clients may still deduct withholding tax (10% for a non-resident's professional fees under the 2024 regulations); whether you can credit it at home depends on your country's rules and any tax treaty with Nigeria.
Working from London, Atlanta or Calgary for clients in Lagos is now ordinary. The tax question has two parts: which country is entitled to tax your income, and what happens to the tax a Nigerian client deducts before paying you. Getting them confused is how freelancers end up paying twice. This is information, not advice; your own adviser should confirm your position.
Step one: where are you resident?
Under the Nigeria Tax Act 2025, as PwC summarises it, an individual is Nigerian resident if they have domicile, a habitual abode, family or economic ties in Nigeria, or are present for 183 days or more. Residents are taxed on worldwide income; non-residents only on Nigerian-source income. Your country of residence applies its own tests, and most tax residents on worldwide income, so your Nigerian client fees almost always belong on your return there.
If both countries treat you as resident, for example because your family home is still in Lagos, a tax treaty decides. The UK-Nigeria agreement looks first at permanent home, then centre of vital interests, habitual abode and nationality. Not every country has a treaty with Nigeria; see Nigeria's tax treaties and the tie-breaker rules.
Step two: is the income Nigerian-source?
The NiDCOM-hosted diaspora guide to the 2026 reforms states that income for services physically rendered outside Nigeria is not taxable in Nigeria unless you are tax resident. So, on that reading, design work done in Manchester for a Lagos client is not Nigerian-source, while a week of workshops delivered in Abuja is. Keep a record of where each piece of work was done.
Step three: the withholding tax your client deducts
Nigerian companies and organisations must deduct withholding tax from service payments under the Deduction of Tax at Source (Withholding) Regulations 2024. For non-residents, PwC lists 10% on professional, consultancy, technical and management fees and 5% on other services, and describes the non-resident company deduction on such fees as the final tax. The rate doubles without a valid tax number. In practice many finance teams deduct on every foreign invoice without considering where the work was done.
How it fits together: an example
Example only: a UK-resident freelancer invoices a Lagos company ₦3,000,000 for work done entirely in the UK, and the company deducts 10%.
| Item | Amount (example) |
|---|---|
| Invoice | ₦3,000,000 |
| Nigerian WHT deducted | ₦300,000 |
| Received | ₦2,700,000 |
| Declared on UK return | The full ₦3,000,000, converted to pounds |
The UK taxes the whole fee because the freelancer is UK resident. Whether the ₦300,000 can be credited depends on the treaty and whether Nigeria was entitled to tax it. The 1987 UK-Nigeria agreement gives credit for Nigerian tax payable under Nigerian law consistent with the agreement; if the work was done wholly abroad and Nigeria should not have taxed it, the home authority may refuse the credit and the route is to ask the client not to deduct, or to seek a refund in Nigeria. Get advice before assuming either outcome.
Reducing the risk of double tax
- Put the place of performance in the contract and on each invoice ("services performed in the United Kingdom").
- Retrieve a Nigerian Tax ID so any deduction is not doubled; see Tax ID from abroad.
- Ask the client before the first payment whether it will deduct WHT and on what basis.
- Collect every WHT receipt.
- Keep a day log if you work in Nigeria during visits.
- Take treaty and credit questions to an adviser in your country of residence.
Trading through a company abroad
If you invoice through your own company registered where you live, the company, not you, is the supplier. Its residence follows its own country's corporate rules, and Nigerian withholding on its consultancy fees is described by PwC as the final Nigerian tax for a non-resident company. Your personal tax then arises when the company pays you salary or dividends at home. The invoice, contract and bank account must all be in the company's name for this to hold together.
Common mistakes
- Leaving Nigerian client income off the home return because tax was already deducted in Nigeria.
- Assuming every Nigerian deduction can be credited at home.
- Converting naira income at a rate you cannot evidence; keep the rate used on each conversion.
- Mixing Nigerian client money with family transfers in one account, which makes income hard to prove.
If you spend long periods in Nigeria
Extended stays can change both sides of the picture: work done in Nigeria is Nigerian-source, and 183 days in Nigeria makes you resident under the NTA. See long visits and freelancer tax risk. The Nigerian side for residents is explained in do Nigerian freelancers pay tax on dollar income.
Where Pryme fits
A Pryme Business Account opened from abroad receives naira and foreign currency with local details, and Swap converts when you choose, rate shown first. The Finance agent can match each payment to its invoice and WHT receipt so your home return and any credit claim rest on complete records.
Questions people ask
Do I pay tax in Nigeria if I freelance from abroad for Nigerian clients?
If you are not Nigerian resident, Nigeria taxes only Nigerian-source income, and the NiDCOM diaspora guide says services performed outside Nigeria are not taxable there. You declare the income where you live.
Why did my Nigerian client deduct 10%?
The 2024 withholding regulations set 10% on non-residents' professional and consultancy fees. Many clients deduct on all foreign invoices.
Can I claim Nigerian withholding tax back in my country?
It depends on your country's rules and any treaty. The UK-Nigeria agreement gives credit for Nigerian tax charged consistently with the treaty. Ask an adviser where you live.
Does 183 days in Nigeria make me tax resident?
Presence of 183 days or more is one of the NTA 2025 residence tests, alongside domicile, habitual abode and family or economic ties.
