Your US client has approved the project. Then accounts payable sends a tax form with an unfamiliar name: W-8BEN. You want the first invoice paid, but the portal asks for a US tax number, a permanent address and a treaty claim. A wrong answer could stay in the client’s records long after the project ends.
Form W-8BEN documents an individual’s foreign status for US withholding and reporting purposes. You normally give it to the requester, not the IRS. It is not your Nigerian tax return, an invoice or proof that every payment you receive is tax-free.
For a Nigerian freelancer, the useful starting questions are simple: are you contracting personally, are you a US person for tax purposes, what kind of income is being paid, and where did you physically do the work? Answer those before copying numbers into boxes. This guide covers ordinary freelance services; US work, entity structures, royalties and uncertain tax status need a separate review.
If the form request arrived alongside your first payment setup, keep the two jobs separate. Our guide to invoicing a US client from Nigeria covers the commercial details the invoice needs. A correct invoice does not replace tax documentation, and an accepted tax form does not confirm a payment method will work.
First confirm why the client requested it
An accounts-payable system may send the same onboarding checklist to every overseas supplier. That explains the request, but it does not decide your status. Ask which legal person is being onboarded and what payment the documentation covers.
Put these records beside the form:
The agreement showing the contracting party’s legal name.
The statement of work describing what you are being paid to do.
Your current address and citizenship information.
A record of where you worked during the project.
Any tax identifiers you have actually been issued.
The requester’s instructions and a secure submission route.
This preparation catches ordinary mismatches. You might use a studio name on social media but sign contracts personally. A client might have entered that studio name as a company in its vendor database. Or its portal might show an old address from an earlier engagement. Correct the underlying vendor record instead of making the form match a mistake.
A useful message is: “The agreement names me personally as the service provider. Please confirm that your tax-document request is for this individual and tell me how to submit it securely.” If the agreement names a company, say so. Do not send a signed individual form simply because you are the only person working in the business.
Check whether the individual form fits your arrangement
W-8BEN is for individuals. Foreign entities generally use W-8BEN-E; US persons generally use W-9. Some arrangements, including disregarded entities and income connected with a US trade or business, have additional rules. A nonresident’s claim concerning compensation for services performed in the US can require other forms. The IRS instructions describe these exceptions.
This is where a short conversation can prevent a long correction. The label “freelancer” does not establish which form is appropriate. Neither does having a Nigerian passport. Someone living in Nigeria could still have US citizenship or another fact affecting US tax status. Someone operating through a registered entity may need documentation for the entity or its owner, depending on the structure.
Use the form-selection question to identify the issue, rather than trying to diagnose an unfamiliar structure from a blog. Give the client’s tax team the relevant facts: the exact contracting name, whether it is an individual or entity, and any US citizenship, residence or work connection. For an entity, keep the registration document available, but share it only through the requester’s approved process.
If the request is routine and the facts are straightforward, you can proceed to the fields. If the facts do not fit the form’s certification, the portal’s insistence is not a reason to sign anyway.
The client’s location does not establish where services were performed
For personal-service income, the IRS generally looks at where the services were physically performed. The payer’s residence, the contract location and the place of payment do not determine that source. Work performed partly inside and partly outside the US can require allocation.
Consider an illustrative designer living and working in Lagos who makes a website for a Chicago business. A US client, USD pricing and US receiving details do not, by themselves, turn those Lagos services into US-source services. That is a sourcing point, not a conclusion that the designer owes no tax anywhere or has no filing duties.
Now change one fact. The designer works on the project during a visit to the US. The project record needs to distinguish that work from the services performed in Nigeria. Do not assume the original onboarding form covers a changed work pattern. Raise the change before the next payment and let the payer or adviser assess the consequences.
Keep the evidence proportionate. For a project completed entirely from your usual location, a dated scope, deliverables and normal business records may explain the work. Travel during a project calls for a clearer timeline: dates, countries and which services were performed where. A payment receipt shows a transfer; it does not describe where you wrote code, designed a page or delivered consulting.
The wider proof-of-income and source-of-funds evidence pack can help organise the commercial record. Keep tax conclusions distinct from the documents supporting your work and income.
Once your documentation is settled, compare walllet.com’s current payment setup with the client’s requirements. Tax documentation and the ability to receive a particular payment are separate checks.
Work through the form without guessing
Download the current form from the IRS or use the requester’s legitimate tax-document system. The IRS page checked for this guide still provides the October 2021 instructions; an older revision date on an official page does not mean you should use an unofficial replacement.
The following review points help you compare the form with records you control. They are not filled-in answers for every Nigerian freelancer.
Area | What to check before entering it |
|---|---|
Legal name | Identify the individual whose foreign status is being documented; resolve a business-name mismatch with the requester. |
Citizenship | Use your actual citizenship information; dual citizenship can require attention to the instructions. |
Permanent residence address | Check the address appropriate to your tax residence, rather than copying a bank’s address or payment provider’s office. |
Mailing address | Check whether it differs from the permanent residence address. |
US tax identifier | Read the conditions for a US SSN or ITIN; a portal field is not proof that every overseas freelancer must obtain one. |
Foreign tax identifier | Confirm the tax identifier issued for the relevant jurisdiction; do not substitute an unrelated account or identity number. |
Reference information | Use the requester’s relevant reference details when appropriate; avoid filling optional space with unnecessary personal data. |
Date of birth | Check both the value and the requested format. |
Treaty claim | Establish eligibility and the applicable provision before making a claim. |
Certification | Read what you are certifying, then sign and date accurately. |
An address error is particularly easy when the onboarding system also stores receiving details. The address associated with a payment service is a payment instruction; it is not automatically your permanent residence. Likewise, a receiving account number is not a tax identification number.
For line 6a and the line 6b exception, read the conditions in the instructions instead of assuming the same requirement applies in every account or payment context. “I have not obtained a number” and “I am not legally required to obtain a number” are different statements. The checkbox is not a convenient way around an unresolved field.
If a Nigerian identifier has recently changed or your records do not establish which identifier the payer expects, ask for confirmation. This guide does not declare a BVN, NIN, company registration number or bank-account number interchangeable with an FTIN. Never enter a made-up number to get through validation.
A focused question works better than “How do I fill this?” For example: “Your portal marks the US tax-identifier field as mandatory. I am documenting an individual performing these services outside the US. Please confirm the basis for requiring a US identifier and the approved way to complete this field.” Let the reply resolve the actual requirement.
Do not borrow a treaty claim from someone in another country
The IRS income-tax treaty list checked on 14 October 2026 does not list Nigeria. Do not claim a treaty reduction merely because you live in Nigeria or because an online example includes a zero rate.
Examples written for Canada, the UK or another treaty jurisdiction can be useful for understanding a form’s layout. Their treaty entries are not transferable to you. Nationality, tax residence and the income covered by a treaty are different facts. A Nigerian citizen genuinely resident elsewhere may need a different analysis, but a foreign receiving address does not establish that residence.
If you are not claiming a treaty benefit, do not invent a treaty country, article number or explanation to make Part II look complete. If a portal will not accept the appropriate treatment, send its tax team a screenshot of the field and the precise problem. Leave sensitive identifiers out of the screenshot unless they are necessary.
The absence of a Nigeria treaty also does not answer every tax question. Income source, US status, the type of income and local obligations still matter. Keep the reasoning in order rather than turning one fact into a universal rule.
Send it securely and keep the accepted version
A completed form contains information you should not post in a freelance group or attach to a public portfolio. Verify the requester through the client relationship you already established. Use its approved secure portal or agreed protected delivery process.
Before submission, compare the saved form with the contract and vendor record. Check that the document is readable, complete and signed as required. If you use an electronic signing process, follow the requester’s accepted procedure; a typed name in an arbitrary document is not something this guide can certify as sufficient.
After sending it, retain the exact submitted version, submission date and acceptance message. A short record might contain the client name, form type, vendor reference, date sent, status and next review date. Store the tax form separately from shareable invoice samples so it cannot be sent accidentally when a prospective client asks for examples.
The general IRS validity period runs through the end of the third calendar year after signing unless a relevant change makes the information incorrect. A form signed in October 2026 would therefore generally run through 31 December 2029, subject to the applicable rules. Relevant changes can require notifying the requester within 30 days and providing appropriate replacement documentation.
Put a reminder in your own records rather than relying on the client’s system to catch everything. Revisit the documentation if your status, address circumstances or work arrangement changes. Explain a correction plainly; do not overwrite a previously signed document while preserving its old signature date.
Set up the payment route as a separate task
The client may approve the tax form and still reject the payment instructions. Its payment system might require a supported transfer rail, the correct beneficiary name or additional supplier verification. Ask accounts payable which payment methods it can actually send before giving it details.
Our guide to receiving payments from US, UK and EU clients in Nigeria explains how country, currency and receiving method fit together. For regular income, the separate USD salary-receiving guide for Nigeria addresses what happens after the funds arrive. Neither replaces this tax-document decision.
Suppose the payer asks for evidence that the receiving account belongs to you. Identify the document it needs rather than sending a tax form again. An account letter, bank statement and transaction receipt serve different purposes. Tax status, account ownership and an individual payment each call for different evidence.
For the first invoice, confirm the agreed amount and currency, invoice reference, payment method and expected process. Record any deduction separately. If the client mentions withholding, ask it to identify the basis, amount and supporting documentation. Do not assume a short payment is tax withholding; fees or another reconciliation issue may be involved. Nor should you assume every foreign payment attracts a flat 30% deduction.
