W-8BEN instructions: how freelancers, authors, bloggers and investors fill out each part of the form

What W-8BEN does, who uses a different form, what lines 1 to 10 ask, how the form is signed, the mistakes that lead to 30% withholding and when a new form is needed, in 2026.

W-8BEN is the form a person outside the United States gives a US payer to confirm foreign status and, where a tax treaty allows, to claim a lower rate of US tax. Freelancers, authors, bloggers and investors meet it before the first payout from a US client, platform or broker.

What W-8BEN does

The top of the form sets the scope: "For use by individuals. Entities must use Form W-8BEN-E."

The instructions list its purposes. The first is to "Establish that you are not a U.S. person".

The payer then works from the form: "A withholding agent or payer of the income may rely on a properly completed Form W-8BEN to treat a payment associated with the Form W-8BEN as a payment to a foreign person who beneficially owns the amounts paid."

The form is not sent to the US tax authority. The instructions say: "Instead, give it to the person who is requesting it from you."

Without it, the default applies: "If you do not provide this form, the withholding agent may have to withhold at the 30% rate (under chapters 3 and 4), backup withholding rate, or the rate applicable under section 1446."

Who uses a different form

The form carries its own list of people who should not use it. US persons appear on it, wherever they live: "You are a U.S. citizen or other U.S. person, including a resident alien individual". Their form is W-9.

Work done inside the United States has its own forms too: "You are a beneficial owner who is receiving compensation for personal services performed in the United States". Such people give Form 8233 or Form W-4.

Business income from the United States goes elsewhere as well: "You are a beneficial owner claiming that income is effectively connected with the conduct of trade or business within the United States (other than personal services)". That income goes on W-8ECI. Murblz experts have described which W-8 form fits companies and other payees in the guide to the W8 form.

First consultation is free. We keep your details private.

Part I, lines 1 to 4: name, citizenship and addresses

Line 1 asks for the "Name of individual who is the beneficial owner". A one-person business is covered by a separate rule: "If you are a foreign individual who is the single owner of a disregarded entity that is not claiming treaty benefits as a hybrid entity, with respect to a payment, you should complete this form with your name and information."

The account name matters here: "If the account to which a payment is made or credited is in the name of the disregarded entity, you should inform the withholding agent of this fact. This may be done by including the name and account number of the disregarded entity on line 7 (reference number) of the form."

Line 2 is citizenship: "Enter your country of citizenship. If you are a dual citizen, enter the country where you are both a citizen and a resident at the time you complete this form. If you are not a resident in any country in which you have citizenship, enter the country where you were most recently a resident."

Line 3 is the home address, and the form itself sets a limit: "Permanent residence address (street, apt. or suite no., or rural route). Do not use a P.O. box or in-care-of address."

The instructions add two rules: "If you reside in a country that does not use street addresses, you may enter a descriptive address on line 3. The address must accurately indicate your permanent residence in the manner used in your jurisdiction."

Line 4 is optional: "Enter your mailing address only if it is different from the address you show on line 3."

Part I, lines 5 to 8: tax numbers and date of birth

Line 5 asks for a "U.S. taxpayer identification number (SSN or ITIN), if required (see instructions)". The instructions begin with the simple case: "If you have a social security number (SSN), enter it here."

Account holders usually fill out line 6a. The instructions say that "you must provide on line 6a the foreign tax identifying number (FTIN) issued to you by your jurisdiction of tax residence identified on line 3".

Line 6b is for those whose country issues no number: "You may check the box in this line 6b if you are an account holder as described for purposes of line 6a and you are not legally required to obtain an FTIN from your jurisdiction of residence (including if the jurisdiction does not issue TINs)." The box counts as an answer: "By checking this box, you will be treated as having provided an explanation for not providing an FTIN on line 6a."

Line 7 is a reference: "A beneficial owner can use line 7 to include the number of the account for which he or she is providing the form."

Line 8 is required for accounts at US banks and brokers: "If you are providing this Form W-8BEN to document yourself as an account holder with respect to a financial account as described above in line 6 that you hold with a U.S. office of a financial institution (including a U.S. branch of an FFI), provide your date of birth."

The format is fixed: "Use the following format to input your information: MM-DD-YYYY. For example, if you were born on April 15, 1956, you would enter 04-15-1956."

Part II: the treaty claim

Line 9 is a sentence the person completes with a country name: "I certify that the beneficial owner is a resident of". The Murblz tax residency calculator shows where a person is resident for tax purposes.

Large sums from a related payer bring an extra filing: "If you are related to the withholding agent within the meaning of section 267(b) or 707(b) and the aggregate amount subject to withholding received during the calendar year exceeds $500,000, then you are generally required to file Form 8833, Treaty-Based Return Position Disclosure Under Section 6114 or 7701(b)".

Line 10 is for special rates and conditions. Investors rarely need it: "This line is generally not applicable to treaty benefits under an interest or dividends (other than dividends subject to a preferential rate based on ownership) article of a treaty."

Freelancers and other businesses do: "Persons claiming treaty benefits on business profits or gains that are not attributable to a permanent establishment must complete this line." The wording is set out too: "Complete line 10 by stating that you derive business profits or gains (other than from real property) not attributable to a permanent establishment. You must also include the relevant treaty article."

Some treaties look at the money brought home: "Some income tax treaties with countries that have a remittance-based tax system only allow treaty benefits on the amount of income that is remitted to (or received in) the treaty country. An individual may use Form W-8BEN to claim benefits under those treaties only on remitted amounts that are taxable in the treaty country."

A short explanation is enough for the payer: "If the beneficial owner is required to explain the additional conditions in the treaty that it meets to be eligible for the rate of withholding on line 10, you may accept a brief explanation for this purpose."

The treaty article and the rate for a given country and type of income are settled at a Murblz consultation. Authors and creators with royalties will find the rules in the Murblz guide to royalty tax.

Part III: the signature

The signature confirms everything above: "Under penalties of perjury, I declare that I have examined the information on this form and to the best of my knowledge and belief it is true, correct, and complete."

An electronic signature is allowed when the payer offers it: "A withholding agent may allow you to provide this form with an electronic signature. The electronic signature must indicate that the form was electronically signed by a person authorized to do so (for example, with a time and date stamp and statement that the form has been electronically signed)."

Mistakes that cost 30% or get the form rejected

The instructions for payers list the reasons a form cannot be trusted. One of them reads: "The form lacks information necessary to establish that the beneficial owner is entitled to a reduced rate of withholding".

Records held by the payer count too: "For example, if you have information in your records that contradicts information provided on the form, you may not rely on the form."

An empty line 6a voids the form for many payments: "If you do not obtain an FTIN on line 6a (when required) and the account holder has not checked line 6b, or provided a further (or other) explanation for why the account holder has not been issued an FTIN on a separate statement (see Foreign TINs, earlier), you must treat the form as invalid for payments of U.S. source income reportable on Form 1042-S (as determined before the application of this requirement)."

The address has to match the treaty claim. A payer has reason to doubt the claim when "The permanent residence address on the form is not in the treaty country or the direct account holder notifies you of a new permanent residence address that is not in the treaty country".

A held-mail address does not work: "An address that is provided subject to an instruction to hold all mail to that address is not a permanent residence address, such that you may not rely upon the Form W-8."

The country on line 3 is safer in full. The instructions for payers treat an abbreviation as a minor slip only with proof on file: "An abbreviation of a country of residence on Form W-8BEN is an inconsequential error if it is an ambiguous abbreviation and you have documentary evidence supporting the beneficial owner's country of residence."

How long W-8BEN lasts

The validity period comes with an example: "Generally, a Form W-8 is valid from the date signed until the last day of the third succeeding calendar year unless a change in circumstances occurs that makes any information on the form incorrect. For example, a Form W-8BEN signed on September 30, 2022, generally remains valid through December 31, 2025."

A move out of the country where treaty benefits are claimed is such a change, with a deadline: "In that case, you must notify the withholding agent, payer, or FFI within 30 days of the move."

Time spent in the United States counts as well: "You may be a U.S. resident for tax purposes depending on the number of days you are physically present in the United States over a 3-year period."

The instructions for payers show how an investor ends up with a second form: "A foreign individual investor opens an account with a broker to purchase U.S. Treasury bonds and provides Form W-8BEN to obtain the portfolio interest exemption. The investor does not complete Part II of Form W-8BEN because he or she is not claiming treaty benefits. Later, the investor purchases U.S. stock and claims treaty benefits on dividend income. The withholding agent must obtain a new Form W-8BEN at that time that provides the information required in Part II to be able to withhold based on the treaty claim and not at the 30% withholding tax rate."

Platforms, banks and brokers that ask for it

Banks and brokers ask even without US income: "An FFI may also request this form from you to document your account as other than a U.S. account."

Marketplaces and payment apps are on the list: "You should provide Form W-8BEN to a payment settlement entity (PSE) requesting this form if you are a foreign individual receiving payments subject to reporting under section 6050W (payment card transactions and third-party network transactions) as a participating payee."

Business income changes the form there too: "However, if the payments are income which is effectively connected to the conduct of a U.S. trade or business, you should instead provide the PSE with a Form W-8ECI."
