US Expat Taxes in Nigeria

Nigeria is one of the most important countries in Africa for American business and expatriate activity — and it is also one where a critical piece of the international tax puzzle is entirely missing. The United States and Nigeria do not have an income tax treaty, which means there are no reduced withholding rates on dividends, interest, or royalties (Nigeria applies a flat 10% across all categories for non-residents), no tie-breaker residency provisions, no mutual agreement procedures, and no totalization agreement for social security. US expats must rely entirely on the Foreign Tax Credit (Form 1116) and Foreign Earned Income Exclusion (Form 2555, up to $130,000 for 2026) to manage dual tax obligations. Nigeria's tax landscape changed dramatically in 2025. On June 26, 2025, President Tinubu signed four landmark tax reform acts into law: the Nigeria Tax Act (NTA), the Nigeria Revenue Service Establishment Act, the Nigeria Tax Administration Act, and the Joint Revenue Board Establishment Act. The NTA replaced the Personal Income Tax Act (PITA) with new progressive brackets — starting at 0% on the first NGN 800,000 and topping out at 25% above NGN 50 million — increased the capital gains tax rate for companies from 10% to 30%, introduced indirect offshore share transfer taxation provisions, and replaced Pioneer Status Incentives with a new Economic Development Incentive (5% annual tax credit on qualifying capital expenditure in priority sectors under Sections 164-172 of the NTA). The Nigeria Revenue Service (NRS) replaced the Federal Inland Revenue Service (FIRS) as the federal tax authority, though the transition is ongoing and FIRS branding remains widely used. The Nigerian Naira has depreciated significantly — from approximately 460/USD in early 2023 to roughly 1,600/USD by late 2025. This has practical implications for US expats: FBAR thresholds are affected (NGN 16 million was worth approximately $35,000 in 2022 but only about $10,000 in 2025), FTC calculations depend on the exchange rate at the time taxes are paid versus when the credit is claimed, and Naira-denominated income converts to substantially lower USD amounts for FEIE purposes. US expats should use the year-end Treasury rate for FBAR and the transaction-date rate or annual average rate (as appropriate) for income tax calculations. Nigeria's Companies Income Tax rate remains 30% for large companies (turnover above NGN 100 million), 20% for medium companies (NGN 25M-100M), and 0% for small companies (under NGN 25M). VAT increased to 10% effective 2026, with scheduled rises to 12.5% in 2028 and 15% in 2030. All federal tax registration, filing, and payment is now handled through the TaxProMax platform (taxpromax.firs.gov.ng), the mandatory online portal operated by the NRS.

Tax Treaty Information

No Tax Treaty
  • NO US-Nigeria income tax treaty exists — the United States and Nigeria have never concluded a bilateral income tax convention
  • Without a treaty, Nigeria applies standard domestic withholding rates: 10% on dividends, 10% on interest, 10% on royalties paid to non-residents. Treaty countries receive reduced rates (e.g., 7.5% WHT vs 10% for non-treaty countries like the US)
  • Nigeria has ratified double taxation treaties with 16 countries: Belgium, Canada, China, Czech Republic, France, Italy, Netherlands, Pakistan, Philippines, Romania, Singapore, Slovakia, South Africa, Spain, Sweden, and the United Kingdom. The ECOWAS regional treaty became effective January 1, 2024. Treaties pending ratification include Kenya, Mauritius, Poland, and South Korea. The US is not among these partners
  • No tie-breaker residency provisions: dual residents must rely on each country's domestic rules to determine tax residency
  • No mutual agreement procedure: disputes about double taxation cannot be resolved through a treaty-based competent authority process
  • No Totalization Agreement: self-employed US citizens in Nigeria owe both US self-employment tax and Nigerian social contributions — there is no mechanism to avoid duplication
  • Form 8833 (Treaty-Based Return Position) is NOT required since no treaty exists. However, Form 5471 (Information Return for US persons owning shares of a foreign corporation) and Form 3520 (Annual Return for Transactions with Foreign Trusts, relevant for certain Nigerian pension arrangements) may apply

FBAR & FATCA Requirements

US citizens in Nigeria must report all Nigerian financial accounts on FinCEN Form 114 (FBAR) if the aggregate value of all foreign accounts exceeds $10,000 at any point during the calendar year. Reportable accounts include Nigerian bank accounts (Access Bank, GTBank, Zenith Bank, First Bank of Nigeria, UBA, Stanbic IBTC, Ecobank, etc.), brokerage and investment accounts, Nigerian pension fund accounts under the Contributory Pension Scheme (managed by PFAs like Stanbic IBTC Pension, ARM Pension, Leadway Pensure), and any other financial accounts held at Nigerian institutions. FATCA Form 8938 applies for expats with foreign financial assets exceeding $200,000 on December 31 or $300,000 at any point during the year. Nigeria signed a FATCA Model 1 Intergovernmental Agreement with the US, requiring Nigerian financial institutions to report US accountholders to Nigerian authorities, who share the data with the IRS. Failure to file Form 8938 carries penalties of $10,000 for late filing, with additional penalties up to $50,000 for continued non-compliance. The Naira's significant depreciation has materially changed FBAR thresholds in practice. An account holding NGN 16 million was worth approximately $35,000 at the 2022 exchange rate but only about $10,000 at the late-2025 rate of roughly 1,600 NGN/USD. This means accounts that previously exceeded the $10,000 threshold may no longer do so, while the dollar amounts at stake have decreased. USD values must be calculated using the year-end spot rate published by the US Treasury. FBAR non-willful penalties can reach $10,000 per account per year; willful violations carry penalties up to the greater of $100,000 or 50% of the account balance. Additional reporting forms: Form 5471 is required for US persons who are officers, directors, or 10%+ shareholders of a Nigerian corporation. Form 3520 applies if you have interests in Nigerian arrangements classified as foreign trusts, which can include certain pension plans. Form 8865 may apply for interests in Nigerian partnerships. The IRS Streamlined Foreign Offshore Procedures allow non-willful late filers to come into compliance by filing 3 years of back returns and 6 years of delinquent FBARs with no penalties assessed.

Foreign Earned Income Exclusion (FEIE)

US expats in Nigeria can qualify for the Foreign Earned Income Exclusion (up to $130,000 for 2026) by meeting either the Bona Fide Residence Test (established genuine residence in Nigeria for a full calendar year) or the 330-day Physical Presence Test (physically present in a foreign country for 330 full days in any 12-month period). Under the 2025 Nigeria Tax Act, personal income tax rates now range from 0% to 25% — replacing the old PITA 7%-24% brackets — which means some expats face a lower Nigerian effective rate, making the FEIE potentially more beneficial than the FTC for employment income. However, the FEIE has important limitations. It only covers earned income (salary, wages, self-employment income); it does not shield passive income such as dividends, interest, or rental income from Nigerian withholding. Self-employment income excluded under the FEIE is still subject to US self-employment tax (15.3%), and since there is no US-Nigeria totalization agreement, you may owe Nigerian social contributions simultaneously. Those with higher earnings, business income, or significant Nigerian withholding taxes often benefit more from the FTC. A blended approach — using FEIE for earned income and FTC for passive income — is sometimes optimal but requires careful calculation since electing the FEIE affects FTC limitation calculations.

Common Tax Issues in Nigeria

  • 1Nigeria Tax Reform 2025: Four landmark acts signed June 26, 2025 — the Nigeria Tax Act (NTA), Nigeria Revenue Service Establishment Act, Nigeria Tax Administration Act, and Joint Revenue Board Establishment Act — overhauled the tax code. The NTA replaced PITA with new personal income tax brackets (0% on first NGN 800,000; 15% on NGN 800K-3M; 18% on NGN 3M-12M; 21% on NGN 12M-25M; 23% on NGN 25M-50M; 25% above NGN 50M). Company capital gains tax increased from 10% to 30%. VAT rises to 10% from 2026, 12.5% from 2028, and 15% from 2030. New provisions for indirect offshore share transfer taxation were introduced
  • 2Nigeria Revenue Service (NRS, formerly FIRS) and Companies Income Tax: The NRS is Nigeria's federal tax authority, replacing FIRS under the 2025 reform. NRS administers Companies Income Tax (CIT) at 30% for large companies (turnover above NGN 100 million), 20% for medium companies (NGN 25M-100M turnover), and 0% for small companies (under NGN 25M). US citizens owning Nigerian companies must comply with NRS filing requirements and coordinate CIT paid with Form 1116 FTC claims. CIT returns are due within six months of the fiscal year end
  • 3Personal income tax under the NTA — state-level administration remains: personal income tax is still administered by State Internal Revenue Services. Lagos residents pay to LIRS; Abuja (FCT) residents pay to FCT-IRS. The new NTA brackets apply from January 2026. Nigerian personal tax allowances include rent (NGN 150,000), transport (NGN 20,000), utility (NGN 10,000), meal (NGN 5,000), and entertainment (NGN 6,000). Personal allowance: 20% of earned income plus NGN 5,000. Children's allowance: NGN 2,500 per child (max 4). Note: verify whether these allowances have been modified under the NTA implementing regulations
  • 4Economic Development Incentive replaces Pioneer Status: The NTA (Sections 164-172) replaced Pioneer Status Incentives with the Economic Development Incentive — a 5% annual tax credit on qualifying capital expenditure in designated priority sectors. US companies with Nigerian subsidiaries benefiting from this incentive must assess how the credit interacts with FTC claims on the US return. A Nigerian tax credit (rather than a tax exemption) may have different FTC implications than the former Pioneer Status zero-CIT treatment
  • 5TIN registration for US citizens: A Tax Identification Number (TIN) is required before any tax filing or business registration in Nigeria. Obtain a TIN via the JTB portal (tin.jtb.gov.ng) or in-person at an NRS office. Required documents: international passport, utility bill, and BVN (Bank Verification Number) or NIN (National Identification Number). The TIN is a prerequisite for opening corporate bank accounts and filing annual returns
  • 6Withholding tax on consulting and management fees: Nigeria levies 10% withholding tax on consulting fees, management fees, technical service fees, and professional fees paid to non-residents. US companies providing services to Nigerian entities should account for this withholding and claim the resulting credit on the US return via Form 1116
  • 7Penalty rates for non-compliance: On the Nigerian side, CIT late filing incurs NGN 25,000 for the first month plus NGN 5,000 each subsequent month. CIT late payment triggers a 10% penalty plus interest at the prevailing commercial rate. PIT non-compliance under the NTA carries penalties of NGN 100,000 for the first month and NGN 50,000 per subsequent month. On the US side, failure-to-file penalties are 5% per month of tax owed (max 25%); failure-to-pay penalties are 0.5% per month (max 25%). FBAR non-willful penalties can reach $10,000 per account per year
  • 8IRS Streamlined Foreign Offshore Procedures: US expats in Nigeria who have not been filing US returns or FBARs can use the IRS Streamlined Foreign Offshore Procedures to come into compliance. This requires filing 3 years of back income tax returns and 6 years of delinquent FBARs, with no penalties assessed if the non-compliance was non-willful. This program is critical for Americans who moved to Nigeria without realizing they still have US filing obligations

Frequently Asked Questions: US Taxes in Nigeria

Does the US have an income tax treaty with Nigeria?
No. The United States and Nigeria have never signed a bilateral income tax treaty. This means no reduced withholding rates on dividends, interest, or royalties (Nigeria's standard 10% applies in full), no treaty-based tie-breaker residency provisions, and no mutual agreement procedure. US expats must use the Foreign Tax Credit (Form 1116) or Foreign Earned Income Exclusion (Form 2555) to manage double taxation. Form 8833 (Treaty-Based Return Position) is not required since no treaty exists.
How do I avoid double taxation in Nigeria without a tax treaty?
Use the Foreign Tax Credit (Form 1116) to claim a dollar-for-dollar credit against US tax for Nigerian income taxes paid — including personal income tax paid to State Internal Revenue Services and CIT paid to the NRS (formerly FIRS). The FTC is subject to basket limitations (general vs. passive income) and you cannot use it to generate a US refund, only to reduce US tax to zero. Excess credits can be carried back one year or forward ten years. Alternatively, the Foreign Earned Income Exclusion (Form 2555) can exclude up to $130,000 of earned income for 2026. The FEIE only covers earned income; passive income like dividends requires the FTC. A blended approach using both tools is sometimes optimal but requires careful calculation. For Americans who have not been filing US returns from Nigeria, the IRS Streamlined Foreign Offshore Procedures allow you to file 3 years of back returns and 6 years of delinquent FBARs with no penalties if the non-compliance was non-willful.
What changed in Nigeria tax law in 2025?
On June 26, 2025, four major reform acts were signed: the Nigeria Tax Act (NTA), Nigeria Revenue Service Establishment Act, Nigeria Tax Administration Act, and Joint Revenue Board Establishment Act. Key changes: new personal income tax brackets (0% on first NGN 800,000 up to 25% above NGN 50M, replacing the old 7%-24% PITA rates); company capital gains tax increased from 10% to 30%; VAT rising from 7.5% to 10% in 2026, 12.5% in 2028, and 15% by 2030; Pioneer Status Incentives replaced by Economic Development Incentive (5% annual tax credit on qualifying capital expenditure); new indirect offshore share transfer taxation provisions; and FIRS replaced by the Nigeria Revenue Service (NRS).
What countries does Nigeria have tax treaties with?
Nigeria has ratified double taxation treaties with 16 countries: Belgium, Canada, China, Czech Republic, France, Italy, Netherlands, Pakistan, Philippines, Romania, Singapore, Slovakia, South Africa, Spain, Sweden, and the United Kingdom. The ECOWAS regional treaty became effective January 1, 2024. Treaties with Kenya, Mauritius, Poland, and South Korea are pending. The United States is not among Nigeria's treaty partners, so US residents pay Nigeria's full 10% withholding rates rather than the reduced 7.5% rate available to treaty-country residents.
How do I get a TIN in Nigeria as a US citizen?
A Tax Identification Number (TIN) is required before any tax filing or business registration in Nigeria. Apply via the Joint Tax Board (JTB) portal at tin.jtb.gov.ng or visit an NRS (formerly FIRS) office in person. You will need your international passport, a utility bill for proof of address, and your BVN (Bank Verification Number) or NIN (National Identification Number). The TIN is also required to open corporate bank accounts. Processing is typically completed within a few business days for in-person applications.
What are the penalties for not filing taxes in Nigeria?
Nigerian penalties: CIT late filing incurs NGN 25,000 for the first month plus NGN 5,000 each subsequent month; CIT late payment triggers a 10% penalty plus interest at the prevailing commercial rate. Personal income tax non-compliance under the NTA carries NGN 100,000 for the first month and NGN 50,000 per subsequent month. Failure to register for VAT carries a penalty of NGN 10,000 per day. US-side penalties: failure-to-file is 5% per month of tax owed (max 25%); failure-to-pay is 0.5% per month (max 25%); FBAR non-willful penalty up to $10,000 per account per year; willful FBAR penalty up to the greater of $100,000 or 50% of account balance; Form 8938 late filing penalty is $10,000 plus up to $50,000 for continued failure; Form 5471 penalty is $10,000 per form per year.
Does Nigeria tax foreign income?
Yes. Nigerian tax residents are taxed on worldwide income under the Nigeria Tax Act. You are considered a Nigerian resident if you are present in Nigeria for 183 days or more in any 12-month period, or if you have a permanent home available to you in Nigeria. Non-residents are taxed only on Nigerian-source income. US citizens who are Nigerian tax residents face taxation by both countries on their worldwide income and must use the FTC or FEIE to mitigate double taxation. Note that Nigeria's definition of 'source' can differ from the US definition — for example, income for services performed partly in Nigeria and partly abroad may be fully sourced to Nigeria under domestic rules, potentially creating mismatches that complicate FTC calculations. US citizens should also be aware that Nigeria taxes capital gains on the disposal of assets situated in Nigeria regardless of the seller's residence.
Do US expats in Nigeria need to pay self-employment tax?
Yes. Because there is no totalization agreement between the US and Nigeria, self-employed US citizens in Nigeria owe both US self-employment tax (15.3% covering Social Security at 12.4% and Medicare at 2.9%, plus the 0.9% Additional Medicare Tax on earnings above $200,000) and any Nigerian social contribution levies. The FEIE does not exempt you from self-employment tax — even if your earned income is excluded under Form 2555, the self-employment tax still applies to the full net self-employment income. You may deduct the employer-equivalent portion (7.65%) as an adjustment on your US return. With no totalization agreement, there is no mechanism to avoid this dual burden. This contrasts sharply with countries like the UK, Germany, or Australia, where totalization agreements allow credits between the two social security systems.
What is TaxProMax?
TaxProMax (taxpromax.firs.gov.ng) is the mandatory online platform operated by the NRS (formerly FIRS) for federal tax registration, filing, and payment in Nigeria. All Companies Income Tax, VAT, withholding tax, and other federal tax returns must be filed through TaxProMax. US citizens with Nigerian businesses or tax obligations should register on TaxProMax with their TIN to file returns and make payments electronically.
Do I need to report Nigerian bank accounts on FBAR?
Yes. US citizens with Nigerian bank accounts at Access Bank, GTBank, Zenith Bank, First Bank, UBA, or any other Nigerian financial institution must file FinCEN Form 114 (FBAR) if the aggregate value of all foreign accounts exceeds $10,000 at any point during the year. FATCA Form 8938 also applies if foreign financial assets exceed $200,000 on December 31 or $300,000 at any time. Given the Naira's depreciation (from ~460/USD in 2023 to ~1,600/USD in late 2025), verify that your account balances still exceed the thresholds using the Treasury's year-end exchange rate.
What IRS forms do US expats in Nigeria need to file?
Common forms include: Form 1040 (US individual return); Form 1116 (Foreign Tax Credit); Form 2555 (Foreign Earned Income Exclusion); FinCEN Form 114 (FBAR, filed separately with FinCEN); Form 8938 (FATCA); Form 5471 (if you are an officer, director, or 10%+ shareholder of a Nigerian corporation); Form 3520 (if you have interests in Nigerian arrangements classified as foreign trusts, including certain pension plans). Form 8833 is NOT needed since no US-Nigeria treaty exists. Schedule SE applies if you have self-employment income in Nigeria.
