W-9 vs W-8BEN for Freelancers (2026): Which Form to Give a US or Foreign Client, 24% vs 30% Withholding and the Cases in Between

Published: October 27, 2026 · Reading time: 11 min

TL;DR: Form W-9 is for U.S. persons: citizens (including those living abroad), resident aliens, and U.S.-formed entities (but a disregarded U.S. entity with a foreign owner uses a W-8 form, not a W-9). Form W-8BEN is for foreign individuals. The two never apply to the same person, and a foreign person is told not to use the W-9. The stakes differ: refusing a W-9 can trigger 24% backup withholding (about $4,320 on an $18,000 payment), while a payer who treats a foreign freelancer's U.S.-source pay as subject to withholding can withhold 30% (about $7,200 on $24,000) if no exemption is documented. A nonresident alien claiming a treaty exemption for services performed in the United States uses Form 8233, and income effectively connected with a U.S. trade or business other than an individual's personal services calls for W-8ECI, which does not cover an individual's personal-services income. A W-8BEN generally lasts through the third calendar year after the year you sign it. Neither form goes to the IRS.

A client emails a PDF with one line: "Please complete this before we can pay you." Sometimes it is a W-9. Sometimes it is a W-8BEN. Sometimes the client's accounts-payable portal asks for one and your tax situation fits neither.

Most guides explain these forms from the paying side: what a business should collect. This one is written from the freelancer's chair. It covers which form is yours, what each one certifies, what it costs you if you send the wrong one or none, and the in-between cases (a green-card holder abroad, a visitor who works while in the U.S., a foreign freelancer with a U.S. LLC). If you are the one paying contractors, see our guide to hiring foreign contractors and our backup withholding guide.

This is general education about federal forms. It is not advice about your treaty, your visa or your residency, which are fact-specific. Where the answer turns on those, the post says so.

The Short Answer: One Question Decides It

Are you a U.S. person for federal tax purposes?

The IRS puts the dividing line in the instructions to each form. The Instructions for the Requester of Form W-9 say:

"For federal tax purposes, a U.S. person includes, but is not limited to: An individual who is a U.S. citizen or U.S. resident alien; A partnership, corporation, company, or association created or organized in the United States or under the laws of the United States; Any estate (other than a foreign estate); or A domestic trust (as defined in Regulations section 301.7701-7)."

And the Form W-9 itself closes the loop from the other direction:

"If you are a foreign person or the U.S. branch of a foreign bank that has elected to be treated as a U.S. person (under Regulations section 1.1441-1(b)(2)(iv) or other applicable section for chapter 3 or 4 purposes), do not use Form W-9. Instead, use the appropriate Form W-8 or Form 8233 (see Pub. 515)."

The Form W-8BEN instructions list who should not use it, and the first item for most freelancers is the one that surprises them:

"You are a U.S. citizen (even if you reside outside the United States) or other U.S. person (including a resident alien individual). Instead, use Form W-9 to document your status as a U.S. person."

So an American freelancer working from Lisbon gives a W-9, not a W-8BEN. Your address does not change your form. See our guide to Schedule C while living abroad for how the foreign earned income exclusion interacts with self-employment tax.

What Each Form Actually Certifies

Form W-9: "Here is my TIN, and I am a U.S. person"

The W-9 is a request for a taxpayer identification number and a certification. The form states that you certify, under penalties of perjury, that the number shown is your correct taxpayer identification number, that you are not subject to backup withholding, and that you are a U.S. citizen or other U.S. person. It is signed and handed to the requester, not to the IRS: the form header reads "Give form to the requester. Do not send to the IRS."

The requester needs it to file information returns. Our guides on Form 1099-NEC vs 1099-MISC and the 1099-NEC threshold change explain which return follows. A W-9 does not by itself make you a contractor rather than an employee; that is a separate question covered in our worker classification guide.

Form W-8BEN: "I am not a U.S. person, and here is my country"

The W-8BEN establishes foreign status. The instructions explain the stakes:

"Foreign persons are subject to U.S. tax at a 30% rate on income they receive from U.S. sources..."

That list of income includes "Compensation for, or in expectation of, services performed." The instructions go on to say the tax "is imposed on the gross amount paid and is generally collected by withholding under section 1441." The form is how a foreign freelancer tells the payer what they are, so the payer can document why a U.S. person's treatment does not apply, and where a treaty benefit is claimed, why a reduced rate may.

You give it to the requester: "Do not send Form W-8BEN to the IRS. Instead, give it to the person who is requesting it from you."

What Goes Wrong: 24% vs 30%

The two forms guard against different mistakes, and the numbers are different.

If you are a U.S. person and don't return a W-9

The W-9 says that if you don't return it to the requester with a TIN you might be subject to backup withholding, and states: "Persons making certain payments to you must under certain conditions withhold and pay to the IRS 24% of such payments." The list of payments that may be subject to it includes "nonemployee pay."

The IRS's requester instructions confirm the rate: "The backup withholding rate is 24% for reportable payments."

Take a designer paid $18,000 who never returns the form:

That $4,320 is not an extra tax. It is an advance payment applied against your income and self-employment tax, and it comes back as a credit when you file. But it arrives months later, and it can wreck a quarter's cash flow. The form also names a $50 penalty for failing to furnish your correct TIN to a requester unless the failure is due to reasonable cause. See our quarterly estimated tax guide for how to keep backup withholding from distorting your estimates.

If you are a foreign individual and no exemption is documented

The Publication 515 rule for independent contractors is blunter:

"You must withhold at the statutory rate of 30% on all payments unless the alien enters into a withholding agreement or receives a final payment exemption (discussed later)."

That sentence is about compensation for independent personal services of a nonresident alien. The 30% applies to the gross amount, not to profit, so no expenses come off first.

Take a nonresident freelancer paid $24,000 for U.S.-source services with nothing documented:

Whether the $7,200 is the final tax depends on the rest of the facts: a treaty, a withholding agreement or Form 8233 exemption described in Publication 515, or a return filed to claim a refund. The point is only that submitting the right form changes the outcome before the money moves.

Where the Work Happens Matters: Source of Income

A foreign freelancer's withholding does not depend only on passport and form. It depends on where the services were performed. Publication 515 puts it this way:

"Income is also from U.S. sources if the property that produces the income is located in the United States, the services for which the income is paid were performed in the United States or the income is a dividend equivalent."

Two facts follow from this, both stated carefully:

• Work performed outside the United States for a U.S. client is generally not U.S.-source compensation. A W-8BEN lets the client document that the payee is foreign. It is the paperwork that keeps the 30% from being applied reflexively.
• Work performed while physically in the United States is U.S.-source, and the payer must treat it under the withholding rules unless a treaty or other exemption is documented. Publication 515 also says income is treated as U.S.-source if its source cannot be determined at payment time, "such as fees for personal services paid before the services have been performed." A freelancer paid up front for a project that will be partly done in the U.S. should expect the payer to be careful.

If you are on the other side of this, a U.S. freelancer with foreign clients, the form questions are different. Foreign clients may not file a 1099, may ask for a W-9 if they have U.S. withholding obligations, or may ask for residency paperwork to apply a treaty rate to their local withholding. Our foreign clients on Schedule C guide covers reporting gross receipts, translating currency and the foreign tax credit, and our Section 988 guide covers currency gains and losses.

The In-Between Cases

Most confusion comes from a person who does not fit neatly under either form.

A nonresident alien who works in the U.S. and claims a treaty exemption: Form 8233

The W-8BEN instructions carve this out:

"You are a nonresident alien individual who claims exemption from withholding on compensation for independent or dependent personal services performed in the United States. Instead, provide Form 8233 or Form W-4."

Publication 515 describes the form as one used "by a nonresident alien individual to claim a tax treaty exemption from withholding on some or all compensation paid for: Independent personal services (self-employment), Dependent personal services, or Personal services income and noncompensatory scholarship or fellowship income from the same withholding agent." The payer must review it, sign to accept it, and forward it to the IRS. Whether a given treaty exempts self-employment income depends on its text, so this is a CPA or EA conversation. Publication 515 itself says that under some treaties pay for independent personal services performed in the United States is taxed as business income, and under others it is exempt only if the contractor performs the services during a limited period.

Income effectively connected with a U.S. business: W-8ECI

The same W-8BEN instructions say not to use it if "You are receiving income that is effectively connected with the conduct of a trade or business in the United States, unless it is allocable to you through a partnership. Instead, provide Form W-8ECI." The W-8ECI instructions add: "This withholding exception does not apply to personal services income performed by an individual," and tell a nonresident alien individual claiming exemption on personal-services compensation to provide Form 8233 or Form W-4 instead. They add that if income you documented on a W-8BEN becomes effectively connected, "this is a change in circumstances and Form W-8BEN is no longer valid with respect to such income."

A foreign freelancer with a company

The W-8BEN is for individuals. The instructions say a foreign entity documenting its status or claiming treaty benefits uses Form W-8BEN-E. A freelancer who operates through a foreign company will usually be asked for the entity version, and what the company is classified as is a separate question from where you live.

A resident alien who is a "visitor" on paper

You can be a U.S. resident for tax purposes without a green card. Publication 519 describes the substantial presence test as being physically present in the United States on at least 31 days during the year and 183 days during the 3-year period that includes the year and the two before it, counting all the days in the current year, one third of the days in the prior year and one sixth of the days in the year before that.

A short example: a freelancer present in the U.S. 100 days in 2026, 150 in 2025 and 210 in 2024 counts 100 + 50 + 35 = 185 days, which is at least 183, so the day-count test is met unless an exception or a closer-connection claim applies. Someone present 120 days in each of the three years counts 120 + 40 + 20 = 180 and does not meet it. Publication 519 also describes exceptions (certain days that don't count) and the closer-connection rule for people who maintain a tax home abroad, so the day count alone does not settle your status. If that count makes you a resident, you are a U.S. person and the W-9 applies instead of the W-8BEN.

A nonresident who becomes a resident

The W-8BEN instructions say that if you become a U.S. citizen or resident alien after you submit the form, you are no longer subject to the 30% withholding rate under section 1441, you must notify the withholding agent within 30 days, and you may be required to provide a Form W-9. A move that changes your status is a change in circumstances, and the old form should not keep running.

A foreign freelancer with a U.S. LLC

Forming an LLC in the United States does not make a nonresident owner a U.S. person. The Form W-9 says: "A disregarded U.S. entity that has a foreign owner must use the appropriate Form W-8." If you are a nonresident alien who owns a single-member LLC, the owner gives the client a W-8BEN (or a W-8BEN-E if the owner is itself an entity), and the withholding rules above are applied to the owner. Certifying U.S.-person status on a W-9 when it is not true is a false certification, so ask a CPA or EA before signing.

A US freelancer with a single-member LLC

An LLC with one owner is generally a disregarded entity, and the W-9 asks you to enter the owner's name on line 1 and the business name on line 2, then check the box for the owner's tax classification. Our single-member LLC on Schedule C guide and EIN vs SSN guide cover which number to give. An LLC that elected corporate or partnership tax treatment follows different line 3a instructions.

How Long a W-8BEN Lasts

Unlike a W-9, which a payer usually keeps until something changes, the W-8BEN has an expiry. The instructions say it generally remains in effect

"for a period starting on the date the form is signed and ending on the last day of the third succeeding calendar year, unless a change in circumstances makes any information on the form incorrect."

The IRS example is a form signed on September 30, 2015, which "remains valid through December 31, 2018." Apply the same pattern to a form signed in 2026, which runs through December 31, 2029. The instructions add that under certain conditions it "will remain in effect indefinitely until a change of circumstances occurs." Many payers simply ask for a fresh form every three years. The instructions say a change of address within the same foreign country or to another foreign country is generally not a change in circumstances, but if you use Form W-8BEN to claim treaty benefits, a move to the United States or outside the country where you have been claiming treaty benefits is a change in circumstances, so do not assume the old form stays good.

Common Mistakes

1. Sending a W-8BEN as a U.S. citizen abroad. The instructions send you to the W-9.
2. Ignoring a W-9 request. The default consequence is 24% backup withholding.
3. Filling in a W-9 with the LLC's name on line 1. For a disregarded entity, line 1 is the owner.
4. Assuming the treaty is automatic. A W-8BEN can claim treaty benefits, but a nonresident alien claiming a treaty exemption on services performed in the U.S. uses the Form 8233 route instead.
5. Treating a W-8BEN as permanent. It lapses on a schedule, and changes in circumstances end it sooner.
6. Not reconciling later. Your records are what you check against the payer's reporting. See how to organize receipts for taxes.
7. Sending the form to the IRS. Neither form goes to the IRS.
8. Not keeping a copy. Keep the signed form and date you sent it, so a later question about your TIN or status has a paper trail.

How CentSense Helps

Whichever form you give, the income still has to be tracked, and the numbers still have to match what the client reports:

• Scan expense receipts with AI the day you pay, so the vendor, date and total are captured. The free tier includes 10 AI scans a month
• Log mileage by date on the Solo plan ($5/month) with a destination and business purpose for each trip
• On the Solo and Team plans, export your categorized expenses as CSV so your preparer can map them to Schedule C

CentSense tracks expenses and mileage. It does not decide whether you are a U.S. person, whether a treaty applies, or which form a payer should accept. Those are questions for the IRS instructions and a CPA or EA.

Frequently Asked Questions

Should a freelancer fill out a W-9 or a W-8BEN?

A W-9 if you are a U.S. person, and a W-8BEN if you are a foreign individual. The IRS says a U.S. person includes a U.S. citizen or resident alien, and that a U.S. citizen who lives outside the United States still uses Form W-9 rather than W-8BEN. A foreign person is told not to use Form W-9 and to use the appropriate Form W-8 or Form 8233 instead. Residency is decided by IRS tests, not by where you feel at home, so ask a CPA or EA if your status is unclear.

What happens if I don't return the W-9 a client asked for?

You might be subject to backup withholding. The Form W-9 says that if you don't return it to the requester with a taxpayer identification number, you might be subject to backup withholding, and the IRS states the backup withholding rate is 24% for reportable payments. On an $18,000 payment that would be $4,320 held back and $13,680 paid to you, which you could claim as a credit on your return. The form also describes a $50 penalty for failing to furnish your correct TIN without reasonable cause. Ask a CPA or EA about your situation.

Does a U.S. citizen living abroad give a W-9 or a W-8BEN?

A W-9. The IRS instructions for Form W-8BEN say not to use it if you are a U.S. citizen, even if you reside outside the United States, and to use Form W-9 to document your status as a U.S. person. Living abroad does not change that, and you still report your worldwide income on a U.S. return, although the foreign earned income exclusion and the foreign tax credit may reduce the tax. Ask a CPA or EA how those provisions apply to your facts.

How long is a W-8BEN valid?

Generally from the date you sign it through the last day of the third succeeding calendar year, unless a change in circumstances makes information on it incorrect. The IRS example is a form signed September 30, 2015 that remains valid through December 31, 2018. Under certain conditions it can stay in effect indefinitely until circumstances change, and the chapter 4 period is determined under separate regulations. A move to the United States or becoming a resident alien is a change you must report promptly, so ask a CPA or EA whether yours needs to be refreshed.

Do foreign freelancers pay 30% U.S. tax on everything a U.S. client pays them?

No. The 30% rate applies to specified U.S.-source income, and Publication 515 says income is generally from U.S. sources when the services were performed in the United States. A foreign freelancer who does the work from abroad is generally paid foreign-source income, and a W-8BEN documents foreign status so the client does not apply the rate. Work done while physically in the United States can be treated differently, and a treaty may reduce or exempt it using Form 8233. Confirm with a CPA or EA before you rely on any of it.

If I run a single-member LLC, whose name goes on the W-9?

Yours, if you are the owner. The Form W-9 tells a sole proprietor or disregarded entity to enter the owner's name on line 1 and the business or disregarded entity name on line 2, and the LLC checks the box for its owner's tax classification. An LLC taxed as a partnership, C corporation or S corporation is different and gives its own information. Check the form's line 3a instructions or ask a CPA or EA if your LLC made an entity-classification election.

Do I send my W-9 or W-8BEN to the IRS?

No. Both forms go to the person asking for them, not to the IRS. The Form W-9 says to give it to the requester and not send it to the IRS, and the Form W-8BEN instructions say the same: give it to the person who requested it. Keep your own copy, since the client keeps it in its records, and reconcile the income it later reports with yours. If the requester asks for more than the form, confirm it with a CPA or EA first.
