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
Form 8833 is the form used to disclose a treaty-based return position, meaning a position on your US return that relies on an income tax treaty to override the normal rules. The United States has no income tax treaty with Nigeria, so a position that depends only on your Nigerian connection cannot be treaty-based, and Form 8833 does not arise. Relief for tax paid in Nigeria comes through the foreign tax credit instead.
What Form 8833 is for
The IRS's About Form 8833 page (August 2026) says the form is used to make the treaty-based return position disclosure required by section 6114 of the Internal Revenue Code, and by dual-resident taxpayers making the disclosure required by Regulations section 301.7701(b)-7. In everyday terms you would file it if you said to the IRS: "Under the treaty between the US and country X, this income is exempt, or taxed at a lower rate, or I should be treated as a resident of X rather than the US."
Typical users are people from treaty countries: a UK pensioner relying on the UK-US treaty, or a student from a treaty country claiming a treaty exemption for a scholarship. All of them need a treaty to point to.
Why it does not arise for Nigeria
The IRS's list of income tax treaties (reviewed January 2026) has no entry for Nigeria. In Africa it lists Egypt, Morocco, South Africa and Tunisia. Where no treaty exists, income is taxed under the ordinary rules in the return instructions. So:
- There is no treaty article to exempt a Nigerian pension, rent, salary or capital gain.
- There is no treaty rate to reduce US withholding on income paid to someone in Nigeria.
- There is no treaty tie-breaker to decide between Nigerian and US residence if you are resident in both.
For the background on why no treaty exists and what that means, see the US-Nigeria tax treaty question.
Where people get confused
"Double taxation agreement" in Nigerian documents
Nigeria has double taxation agreements with several countries, and Nigerian withholding tax tables, such as PwC's (May 2026), show reduced treaty rates for some of them. The United States is not among the treaty rates shown. If a Nigerian bank or tenant applies a reduced rate to you because you live in the US, ask what agreement they are relying on.
The dual-resident box
Since the Nigeria Tax Act 2025 widened Nigerian residence tests, more people are resident in both countries at once; see Nigerian residence after moving. A treaty tie-breaker would normally resolve that, with Form 8833 as the disclosure. With no US-Nigeria treaty, you cannot elect out of US residence on that basis. You remain a US resident under the green card or substantial presence test, and Nigeria applies its own rules.
Treaties with third countries
Form 8833 can still matter to a Nigerian in the US who has income from a treaty country, for example a pension from years in the UK, or who holds another nationality and residence. That use rests on the other country's treaty, not on Nigeria.
What to use instead
| Your problem | The tool without a treaty |
|---|---|
| Tax paid in Nigeria on Nigerian income | Foreign tax credit on Form 1116, or a deduction |
| Living and working in Nigeria for a long period | Foreign earned income exclusion (Form 2555), if you meet its tests |
| US income paid to your parents in Nigeria | 30% US withholding unless a specific exemption applies; Form W-8BEN documents foreign status |
| Resident in both countries | Each country taxes under its own rules; credits reduce double tax |
The IRS foreign tax credit page (July 2026) allows a credit for foreign income taxes on income also taxed by the US. For a US resident with Nigerian rent or interest that is the main relief. Our step-by-step guide is foreign tax credit for tax paid in Nigeria.
A worked example
Example only; figures invented. Yemi, in Chicago, receives ₦4,500,000 of rent on a Lekki flat, with 10% Nigerian withholding tax. A friend tells him to file Form 8833 to claim the rent is "treaty-exempt". There is no treaty, so that position is not available and filing it would be wrong. Instead he reports the rent on Schedule E and claims the ₦450,000 withheld as a foreign tax credit, converted to dollars at the rate on the date paid, subject to the Form 1116 limit.
What to check first
- Is there a treaty between the US and the other country involved? For Nigeria, no.
- If a preparer proposes a treaty position involving Nigeria, ask which article of which treaty.
- Claim Nigerian tax through Form 1116 and keep the withholding tax credit notes.
- If you also have income from a treaty country, look at that treaty separately.
Where Pryme fits
Without a treaty, the foreign tax credit depends on evidence that Nigerian tax was actually paid. Keeping Nigerian income in one naira account, and saving the withholding credit notes alongside the statements, makes that evidence easy to produce. Pryme statements can be made verifiable through VerifyDoc.ai (receipts and statements), and the account can be opened from the US (open an account).
Questions people ask
Do I need Form 8833 for Nigerian income?
No. Form 8833 discloses positions based on an income tax treaty, and the US has no income tax treaty with Nigeria.
Is there a US-Nigeria tax treaty?
No. The IRS treaty list, reviewed January 2026, has no Nigeria entry.
How do I avoid double tax on Nigerian income without a treaty?
Claim the Nigerian income tax as a foreign tax credit on Form 1116, subject to its limits.
Can I use Form 8833 to be treated as a Nigerian resident instead of a US resident?
No. That disclosure depends on a treaty tie-breaker, and there is no US-Nigeria treaty.
