How to Fill W-8BEN Part I — Line-by-Line Instructions

Form W-8BEN Part I is the identity section every non-U.S. individual must complete before a U.S. payer can apply reduced withholding—or any withholding rate other than the default. Lines 1 through 8 capture who you are, where you live for tax purposes, which tax identification numbers apply, and your date of birth. Payers read Part I first when deciding whether your certificate is complete enough to rely on.

Get Part I wrong and the consequences are immediate: your form may be rejected, payouts delayed, or tax withheld at 30% on U.S.-source payments until a corrected certificate is accepted. Many freelancers, creators, and consultants discover these problems only after a platform flags their tax settings or a client says the PDF does not match their records.

This guide walks through each Part I line with practical examples for individuals who receive U.S.-source income—freelance fees, royalties, dividends, or platform payouts. It explains what the IRS form asks for, how payers use your answers, and how Part I connects to Part II treaty claims. This page is informational guidance on how to fill the W-8BEN form; it is not individualized tax or legal advice.

Line 1 — Name of individual

Line 1 asks for the full legal name of the individual who is the beneficial owner of the income. This is not a nickname, a brand name, or your company name unless you are a sole proprietor and the payer pays you personally under that exact legal identity. The name on Line 1 must match the name on your government-issued ID and, where relevant, the name tied to the tax identification number you enter on Line 6.

• Use your legal name: Enter the name exactly as it appears on your passport, national ID card, or other official identification document. Include all given names and your family name in the order the form expects.
• Match your bank and contract: If your invoice, contract, or payout account is in a different spelling, align them before submitting W-8BEN. Payers compare Line 1 to their vendor records.
• Individuals only: Do not enter a company name on W-8BEN. Corporations, LLCs, and partnerships file Form W-8BEN-E instead. See W-8BEN vs W-8BEN-E if you are unsure which form applies.
• Sole proprietors paid personally: If the U.S. client pays you as a natural person—even when you run a one-person business—Line 1 is usually your personal legal name, not your trade name alone.
• Why accuracy matters: A mismatch between Line 1 and Line 6, or between the form and your ID, is one of the fastest reasons payers reject a certificate and revert to default withholding.

Before you move to address fields, confirm you are filing the right form type. Part I of W-8BEN certifies that you are an individual who is not a U.S. person. If any field in Part I would be more natural for a legal entity, stop and verify you need W-8BEN-E instead.

The IRS publishes the current form revision and field descriptions on the IRS W-8BEN page. Line numbers in this guide follow the standard individual form; confirm against the revision your payer accepts.

Line 2 — Country of citizenship

Line 2 asks for your country of citizenship—the nation that issued your passport or that considers you a citizen under its laws. This is not the same as your country of tax residence, although for many people the two countries are identical. Payers and the IRS use Line 2 together with your address lines to understand your status; it does not by itself determine treaty benefits.

• Citizenship vs tax residence: You may be a citizen of Country A but tax resident in Country B if you live and pay income tax in B. Line 2 is citizenship; Lines 3–4 and Part II Line 9 reflect tax residence.
• Dual citizens: If you hold two passports, enter the citizenship that best matches your circumstances and be consistent with the country whose treaty you may claim in Part II.
• Not a substitute for address country: Do not enter the United States on Line 2 unless you are a U.S. citizen. U.S. persons generally cannot use W-8BEN to certify foreign status.
• Consistency across the form: A citizenship country that conflicts with your permanent address country without explanation can trigger payer review—even when both entries are technically correct for a cross-border resident.

Line 3 — Permanent residence address

Line 3 is your permanent residence address—the place where you live and are subject to tax as a resident under local law. Enter a complete street address, city or town, postal code if your country uses one, and country. This must reflect your real tax residence, not a mail-forwarding service, a relative's home you do not live in, or a virtual office used only for correspondence.

U.S. withholding agents rely on Line 3 when validating that you are a foreign individual. Entering a U.S. street address while certifying foreign status on the same form is a common rejection trigger. If you moved recently, use the address where you are currently tax resident; outdated addresses can undermine treaty claims in Part II. For background on why residency documentation matters, see US withholding tax for non-residents.

Line 4 — Mailing address

Line 4 is for your mailing address when it differs from the permanent residence address on Line 3. Many individuals leave Line 4 blank or write 'Same as Line 3' only if the form instructions and payer portal allow that shorthand—otherwise repeat the full address from Line 3.

• When Line 4 matches Line 3: If mail is delivered to your home and that home is your tax residence, duplicate the Line 3 address in Line 4 or follow the payer's guidance for indicating they are identical.
• When addresses differ: Use Line 4 for a P.O. box, business mail room, or secondary address where you reliably receive post—while Line 3 still shows your permanent residence for tax purposes.
• P.O. boxes on Line 3: Some payers reject a P.O. box alone on Line 3 because it does not prove street-level residence. Prefer a full residential address on Line 3 and put the P.O. box on Line 4 if needed.
• Country field: The country on Line 4 should match the mailing location. If Line 3 is in Germany and Line 4 is a P.O. box in Germany, both country entries should still align with your tax residence facts.

Line 5 — U.S. taxpayer identification number (if any)

Line 5 is for a U.S. taxpayer identification number—typically a Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN)—only if you have been issued one and the form instructions require you to provide it. Most foreign individuals who have never worked in the United States or filed a U.S. tax return leave Line 5 blank.

Do not invent a U.S. number or copy a colleague's SSN. Entering a U.S. TIN you do not hold is a serious certification error. If you obtained an ITIN for a prior U.S. filing obligation, enter that number exactly as issued. When in doubt, consult current IRS form instructions or a qualified tax adviser before signing under penalties of perjury.

• SSN: Generally for U.S. citizens and residents. Foreign individuals who are not U.S. persons usually do not have an SSN and leave Line 5 empty.
• ITIN: Some non-U.S. persons hold an ITIN from a prior U.S. tax filing. Enter it on Line 5 only when it applies to you—not as a substitute for your foreign TIN on Line 6.
• Blank is normal: An empty Line 5 is expected for most freelancers and creators abroad who rely on their home-country tax ID on Line 6 instead.
• Payer requirements: A few platforms insist on a U.S. TIN for certain treaty positions. Read the payer's help article alongside the IRS instructions before you sign.

Line 6 — Foreign tax identifying number

Line 6 asks for your foreign tax identifying number—the tax ID your home country assigns to individuals. For most non-U.S. residents this is your national tax identification number, not a U.S. SSN. Payers use Line 6 to match your certificate to tax authority records and to process treaty claims in Part II. Leaving Line 6 blank when a number is expected can block reduced withholding even when the rest of the form looks complete.

1. What to enter: Enter your foreign tax identification number—your national tax ID issued by your country of tax residence. Use the format your domestic tax authority expects, without spaces or punctuation if the payer's portal is strict.
2. Name and TIN must match: The identifier on Line 6 must belong to the person named on Line 1. Mismatches are a top reason platforms reject W-8BEN uploads.
3. When Line 6 may be left blank: Some payers accept a blank foreign TIN when IRS instructions allow and no treaty rate is claimed—but many marketplaces require a number for onboarding. Check both the form instructions and your payer's policy.
4. Not a U.S. number: Do not put an SSN or ITIN on Line 6 unless IRS instructions specifically direct you to do so for your facts. Line 5 is for U.S. TINs; Line 6 is for foreign TINs.
5. Treaty claims in Part II: After Part I is correct, reduced withholding usually requires a complete Part II. Read How to complete W-8BEN Part II for treaty benefits before you claim a rate below 30%.
6. Common mistakes: Wrong ID type, expired numbers, or a company VAT number instead of a personal tax ID are frequent Line 6 errors. See 7 common W-8BEN mistakes for a broader checklist.

Line 7 — Reference number(s)

Line 7 is optional on most W-8BEN revisions. Use it only when your withholding agent asks you to supply an internal reference—such as a vendor ID, employee number, or account code—that helps them match the form to your profile in their system. Leave Line 7 blank if the payer did not request a reference and you have no standard identifier to provide.

Line 8 — Date of birth

Line 8 requires your date of birth in MM-DD-YYYY format—the month first, then day, then four-digit year, as used on U.S. government forms. Payers use this field to distinguish individuals with similar names and to satisfy their own know-your-customer checks. Enter the date exactly as it appears on your passport or national ID.

• MM-DD-YYYY format: Example: 15 March 1990 is written 03-15-1990. Reversing day and month is a common data-entry error that can cause payer systems to reject the form.
• Match your ID: If your official documents show a different calendar convention, convert carefully to the U.S. order before you sign.
• Privacy: Your date of birth appears on the certificate you give the withholding agent. Submit W-8BEN only through secure channels your payer provides—not in unencrypted email unless they explicitly allow it.
• After Line 8: Part I ends at Line 8. Part II (treaty benefits), Part III (certification), and the signature block follow. Completing Part I correctly is the foundation before you claim any reduced rate.
