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
Nigerian clients ask for a Tax ID because the Nigeria Tax Administration Act 2025 requires taxable persons to register, ties Tax IDs to contracts with government bodies, and because withholding tax receipts are issued against one. A US freelancer who is non-resident does not automatically need one, but without it a client may deduct more tax. Ask what the number is for, then give your Nigerian Tax ID if you have one, or explain your status in writing.
Why the question comes up
From 2026 Nigerian finance teams are stricter about Tax IDs, and for good reasons. The Nigeria Tax Administration Act 2025 says every taxable person must register and obtain a Tax ID (section 4). Contracts with federal and state agencies and local governments are conditional on one (section 8(1)(c)). A statutory body or company that awards a contract to an unregistered person faces a ₦5,000,000 penalty under section 100(2). And when a client deducts withholding tax, it files that deduction against the supplier's details.
So when a Lagos client says "send your TIN", it is usually one of three things: their vendor onboarding form has a mandatory field, their tax team wants to file withholding tax against you, or they want to avoid a penalty for contracting with an unregistered person.
Do you need a Nigerian Tax ID?
Section 6 of the same Act requires a non-resident supplying taxable goods or services to Nigeria to register for a Tax ID, and notes that a non-resident with only passive income may not need to. For individuals, the NGEX diaspora guide hosted by NiDCOM (January 2026) says the NIN serves as the Tax ID. The same guide says a Tax ID is not generally required unless you have Nigerian employment or business income, while non-residents are taxed only on Nigerian-source income.
The two do not fit neatly. Our reading, which is information rather than advice: if you are a Nigerian citizen with a NIN, you already have the basis of a Tax ID, and supplying it is the simplest way to satisfy a client. If you are not, or have no NIN, ask whether the client really needs a Nigerian number or only needs to record you as a foreign vendor. For how to retrieve or obtain one from abroad, see getting a Nigerian Tax ID from the US.
What you can give them
| Situation | What to provide |
|---|---|
| You have a NIN or an existing Nigerian Tax ID | Your Tax ID, plus your full name exactly as registered |
| You trade through a US LLC with an EIN | The LLC's legal name, EIN, address and a note that it is a foreign company not registered in Nigeria |
| You are a US sole proprietor with no Nigerian number | A letter stating you are a non-resident individual, your US address and country of tax residence; an EIN if you have one |
| Client asks for your SSN | Decline politely. A Nigerian payer has no use for it, and an EIN serves as a business number |
An EIN is free from the IRS. The SS-4 instructions explain that applicants with a US residence and a principal officer holding an SSN or ITIN can apply online; others use phone, fax or mail. Using an EIN on invoices keeps your SSN out of foreign vendor databases.
Withholding tax with and without a Tax ID
PwC's Nigeria withholding tax table (reviewed May 2026) shows 10% for non-resident individuals on commission, consultancy, technical, management and professional fees, and 5% on other services. PwC also reports that vendors without a valid Tax ID face withholding at twice the normal rate, up to 20%, other than on passive income. Whether that doubled rate is applied to non-residents is not clear from the sources we read, but clients often apply it to anyone without a number.
Worked example (illustrative)
An invoice of ₦2,000,000 for consultancy. At 10%, the client deducts ₦200,000 and pays ₦1,800,000. If it applies a doubled 20% rate, it deducts ₦400,000 and pays ₦1,600,000. On a $1,000-equivalent job that is the difference between losing a tenth and a fifth of the fee before conversion. Whichever rate applies, ask for the withholding tax receipt; it supports a possible US foreign tax credit.
Keep your details consistent
Whatever you supply, use the same legal name, address and number on the vendor form, the contract and every invoice. Mismatches are a common reason Nigerian payments stall in finance review. If you trade through a US LLC, contract in the LLC's name and invoice from it; if you work as an individual, use your name exactly as it appears on your passport. Keep a short vendor pack ready: a cover letter on your status, your EIN letter, bank or account details, and a sample invoice, so each new client gets the same set.
A reply you can adapt
Where Pryme fits
Pryme does not issue tax numbers. What it can do is keep each payment, deduction and receipt together: Nigerian clients can pay into a Pryme account opened from the US, and a verifiable receipt from VerifyDoc.ai records the amount received. For WHT credits, read claiming Nigerian WHT as a foreign tax credit and getting WHT credit notes back.
Questions people ask
Why is my Nigerian client asking for my TIN?
Usually for vendor onboarding, to file withholding tax against you, or to avoid the ₦5,000,000 penalty in the Nigeria Tax Administration Act 2025 for contracting with an unregistered person.
Does a non-resident freelancer need a Nigerian Tax ID?
Section 6 of the Act requires non-residents supplying taxable services to Nigeria to register. For individuals, the NIN serves as the Tax ID, per the NiDCOM-hosted NGEX guide.
Should I give a Nigerian client my SSN?
No. An EIN can serve as your US business number on invoices and forms.
What happens if I have no Tax ID?
The client may deduct withholding tax at a higher rate; PwC reports doubled rates up to 20% for vendors without a valid Tax ID.
