Key Facts

UK-Nigeria Double Tax Agreement (1987)

The Convention Between the United Kingdom and the Federal Republic of Nigeria for the Avoidance of Double Taxation was signed in 1987 and remains in force. Key provisions: Article 15 (employment income) — taxed where work is performed; Article 10 (dividends) — UK/Nigeria withholding rates reduced for treaty residents; Article 11 (interest) — withholding reduced; Article 12 (royalties) — withholding reduced. The DTA provides a residency tiebreaker for individuals who might otherwise be treated as resident in both countries (Article 4 — based on permanent home, center of vital interests, habitual abode, nationality). For Nigerians moving to the UK: if you break Nigerian tax residency (typically by spending fewer than 183 days in Nigeria and having no significant Nigerian connections), UK tax residency applies and the DTA prevents the same income from being taxed in both countries. For ongoing Nigerian-source income (business income, rental properties, investments) while living in the UK: FTC for Nigerian taxes paid offsets UK tax on the same income.

UK Non-Dom Reform 2025: The Temporary Repatriation Facility

Historically, non-UK-domiciled UK tax residents could use the 'remittance basis' — paying UK tax only on foreign income and gains actually remitted (brought into) the UK. Many Nigerian immigrants in professional roles used the remittance basis for Nigerian business income, rental income, and investments that remained in Nigeria. From April 6, 2025: the remittance basis is abolished. Replacement: a new Foreign Income and Gains (FIG) regime. New arrivals (who have not been UK tax residents in any of the 10 years before the current tax year): 4-year relief period during which foreign income and gains are exempt from UK tax regardless of remittance. After 4 years: worldwide taxation applies (same as UK-domiciled residents). Temporary Repatriation Facility (TRF): those who used the remittance basis and have pre-April 2025 foreign income/gains not yet remitted can bring these funds to the UK at a preferential 12% tax rate (2025/26 and 2026/27) or 15% (2027/28). Impact for Nigerians: new UK arrivals from Nigeria get a 4-year tax holiday on Nigerian-source income; established non-doms with unremitted Nigerian income should evaluate the TRF window.

UK Tax Residency: Statutory Residence Test

UK tax residency is determined by the Statutory Residence Test (SRT) introduced in 2013. A Nigerian arriving in the UK becomes UK tax resident if they: (1) spend 183+ days in the UK in a tax year (automatic UK resident); (2) have their only home in the UK for at least 91 days; (3) work full-time in the UK for a period covering more than 365 days. Automatic non-residence: spend fewer than 16 days in UK (if UK resident in any of prior 3 years) or fewer than 46 days (if not UK resident in any of prior 3 years). The 'sufficient ties' test: for those in between, UK and family/work/accommodation ties are counted to determine residency status. Tax year: April 6 to April 5 (UK fiscal year). Year of arrival: split-year treatment may apply — you're only UK tax resident from the date of arrival, not for the full year. Split-year means only income earned after UK arrival is subject to UK tax for the first year.

Nigerian Tax Obligations as a UK Resident

Nigerian federal income tax (PITA — Personal Income Tax Act): Nigerian residents are taxed on worldwide income. However, Nigerians who leave Nigeria and establish non-residency (fewer than 183 days in Nigeria, no permanent home in Nigeria, no significant Nigerian business presence) are taxed only on Nigerian-source income. As a Nigerian-origin UK resident: you may owe Nigerian tax on: rental income from Nigerian property; business income from a Nigerian business you actively run; dividends from Nigerian companies (subject to withholding tax at source). Nigerian FIRS (Federal Inland Revenue Service): personal income tax administration for employees is handled by state-level tax authorities (LIRS — Lagos Internal Revenue Service, etc.); for businesses and investment income, FIRS. Withholding Tax (WHT) in Nigeria: 10% on dividends, 10% on interest, 10% on rent. These withheld amounts create a credit against UK tax via the DTA / FTC mechanism. File Form SA106 (HMRC) to claim UK relief for Nigerian taxes paid.

UK PAYE, National Insurance, and Skilled Worker Visa

Nigerians in the UK on a Skilled Worker visa (formerly Tier 2) are fully subject to UK PAYE (income tax and National Insurance) from day one of employment. UK income tax rates (2024/25): personal allowance £12,570 (note: personal allowance reduces by £1 for every £2 above £100,000, eliminated at £125,140); 20% (£12,571–£50,270); 40% (£50,271–£125,140); 45% (above £125,140). National Insurance: employee rate 8% on earnings £12,570–£50,270; 2% above £50,270. Employer rate ~13.8% above the secondary threshold. No separate FBAR equivalent in the UK, but overseas assets disclosures may be required on SA108 for capital gains and SA106 for foreign income. Graduate visa holders: same tax obligations as Skilled Worker visa holders — full PAYE and NI from employment start. NHS surcharge: paid as part of visa application; covers NHS healthcare entitlement. Student visa → Graduate visa: during the student visa period, you are taxed on UK-source income; foreign income falls under normal residency rules.

Nigeria is one of the top five countries of origin for skilled migrants to the United Kingdom, with Nigerians forming one of the UK's largest and most economically active immigrant communities. The UK and Nigeria have a Double Taxation Agreement (1987), and the UK's historically distinctive 'domicile' concept — which allowed non-UK-domiciled residents to potentially use the remittance basis for foreign income — has undergone significant reform from April 2025. This guide covers the tax framework for Nigerians moving to the UK and establishing UK tax residency, with particular focus on the post-2025 non-dom reform and how it affects Nigerian immigrants with ongoing Nigerian income.

Moving to the UK from Nigeria: First Steps for Tax Compliance

Arriving Nigerians should take these tax compliance steps early:

1. Get a National Insurance number: Apply at a UK Jobcentre Plus or online immediately upon arriving. Required before starting work. PAYE deductions cannot be finalized without an NI number (emergency tax code may apply initially).

2. Inform HMRC of your arrival: If you have any UK income before formal employment starts (freelance work, rental income), register for Self Assessment. The employer handles PAYE registration for regular employees.

3. Open a UK bank account: Required for payroll and HMRC refunds. Many UK banks offer accounts for new arrivals — Monzo, Starling, and Wise offer quick digital setup without a lengthy UK credit history.

4. Understand your Nigerian obligations: Notify the Nigerian tax authority (state IRS) and any Nigerian bank accounts of your UK residency status if relevant. Ensure withholding taxes on Nigerian-source income are properly documented.

5. First Self Assessment return: May be required if you have Nigerian-source income, capital gains, or other income outside PAYE. Filing deadline: October 31 (paper) or January 31 (online) for the prior April 5 tax year end.

Frequently Asked Questions

Q: I have a house in Lagos generating rental income — do I pay UK tax on it?

Yes, as a UK tax resident you are subject to UK income tax on worldwide income including Nigerian rental income. You report the net rental income (rents received minus allowable expenses) on your UK Self Assessment return (SA106 — Foreign income supplement). Convert NGN amounts to GBP using HMRC's published average exchange rates. Nigerian withholding tax at source (10% on rents) generates a UK foreign tax credit to reduce UK tax on the same income. If your Lagos rental is your only foreign income and the Nigerian WHT roughly offsets the UK tax at 20% (basic rate), the net UK additional liability may be small. At higher UK tax rates (40%/45%), there may be additional UK tax owed above the Nigerian WHT credit. Under the new 4-year FIG regime (if you arrived in the UK from Nigeria after April 6, 2025 with no UK residency in the prior 10 years), your Lagos rental income is exempt from UK tax for up to 4 years.

Q: Can I send money to Nigeria without paying UK tax?

Transferring money you've already earned and paid UK tax on from the UK to Nigeria is not a taxable event — it's a movement of post-tax funds. HMRC does not tax outbound remittances. Wise is widely used for NGN transfers to Nigeria due to competitive exchange rates and transparent fees. For large transfers: there are no UK reporting requirements for outbound personal transfers. Nigerian recipients may need to account for naira-denominated receipts under Nigerian exchange control regulations (CBN rules), but this is a Nigerian foreign exchange compliance matter, not a UK tax issue. If you are sending money to Nigeria that represents foreign income you've not yet remitted under the old non-dom remittance basis (pre-April 2025): the act of sending it to Nigeria rather than the UK does not trigger the remittance basis charge — remittance basis taxation only applies to funds brought into the UK.

Q: Do I need to tell FIRS (Nigerian tax authority) that I've moved to the UK?

There is no formal departure notification requirement equivalent to the US expatriation rules for Nigerian citizens moving abroad. However, if you were registered with a Nigerian state IRS for PAYE (employer payroll) purposes, your employer should have deregistered you on cessation of Nigerian employment. For Nigerian business income, rental income, or investment income continuing after departure: FIRS and your state IRS maintain jurisdiction over Nigerian-source income regardless of where you live. Ensure any Nigerian-source income subject to withholding (dividends, interest, rent) has WHT properly deducted at source — this creates the credit for UK purposes and demonstrates Nigerian tax compliance. If you own a Nigerian company: corporate tax obligations continue to apply to the company; your personal income from that company (dividends, salary) is subject to both Nigerian and (as a UK resident) UK tax rules with treaty relief.

Disclaimer: This guide provides general tax information for educational purposes only. UK non-dom rules underwent major reform from April 2025 — the new 4-year FIG regime and TRF provisions are recent and subject to HMRC clarification. Nigerian PITA and FIRS rules are subject to change. Nothing in this guide constitutes tax or legal advice. Consult a UK tax advisor familiar with Nigerian-origin taxpayers for advice specific to your situation.
