W-9 vs W-8: which tax form do expats need?
For 2026 payer documentation tied to 2025 payments, Form W-9 is for US persons, while the W-8 series documents foreign status. The main ECI certificate is W-8ECI, used by a foreign beneficial owner to claim that specified income is effectively connected with a US trade or business.
For a W-9 vs W8 request, start with tax status, not your address. A US citizen living abroad is still a US person, while a foreign national may become a resident alien under the substantial presence test.
The IRS withholding-related form bank lists the W-8 series and W-9 among payer documentation forms. Our US tax forms for expats guide explains where these forms fit with annual filing.
Foreign persons also need the right withholding treatment. The IRS overview of taxation of nonresident aliens explains why income type, source, and connection to a US trade or business matter.
The core rule is status first: W-9 for a US person, a suitable W-8 for a foreign person, and W-8ECI only when its ECI certification rules fit.
| Form | Who uses it | Who receives it | Main withholding effect |
|---|---|---|---|
| W-9 | US person | Bank, client, broker, platform, or other requester | A valid W-9 can prevent 24% backup withholding when the payee is otherwise subject to it |
| W-8BEN / W-8BEN-E | Foreign individual/foreign entity | Withholding agent or requester | Documents foreign status and may support a treaty rate or other chapter 3/4 treatment |
| W-8ECI | Foreign beneficial owner claiming specified income is ECI | Withholding agent or requester | Properly documented ECI is generally not subject to chapter 3 or 4 withholding, subject to special rules |
What is Form W-9, and who should use it?
Form W-9 is the March 2024 IRS form a US person uses to give a taxpayer identification number, or TIN, to a requester for information reporting. US citizens abroad, green card holders, resident aliens, and US domestic entities can fall within the W-9 rules.
A US alien tax status review helps noncitizens determine whether they are resident or nonresident for federal tax purposes. Residence abroad does not turn a US citizen into a foreign person.
The following three points explain what Form W-9 does:
- It collects the payee's legal name, federal tax classification, address, and TIN.
- The US person signs certifications about the TIN, backup withholding, US status, and any FATCA exemption code entered.
- The requester uses the data for information reporting and to determine whether backup withholding applies.
A TIN may be an SSN, EIN, or ITIN, depending on the taxpayer. The IRS TIN guidance explains the main federal identification numbers a payee can provide on Form W-9.
NOTE! Give Form W-9 to the requester, not the IRS. If a nonexempt payee fails to provide a correct TIN or another backup-withholding trigger applies, the payer may have to withhold 24% from reportable payments.
So, what is a W8 and W9 form? W-9 certifies US-person information to a requester. A W-8 form documents foreign status and, depending on the subtype, treaty, FATCA, intermediary, exempt-status, or ECI information.
W-9 and W-8 are payer documentation forms, not annual income tax returns. The US tax form W8 W9 choice starts with whether the payee is a US person or a foreign person.
A US citizen freelancing from France still gives a US client Form W-9. See why US citizens living abroad remain subject to US filing rules.
What is Form W-8, and when is it used?
The W-8 family contains five main IRS certificates used to document foreign status and, where relevant, treaty claims, FATCA status, ECI, exempt status, or intermediary status. The right form depends on the payee, the income, and the role the payee has in the payment.
The tax form W8 and W9 choice is not based on mailing address alone. Foreign persons with US tax exposure may need a W-8 even when they live far outside the United States.
The following four situations commonly lead to a W-8 request:
- A foreign freelancer or service provider receives a request for tax documentation from a US client or platform.
- A foreign beneficial owner receives US-source interest, dividends, or royalties.
- A foreign investor opens or maintains an account with a financial institution that must document status.
- A bank, broker, or other withholding agent needs foreign-status documentation before making a payment.
The subtype matters. A foreign individual may use W-8BEN, a foreign entity may use W-8BEN-E, and a foreign beneficial owner claiming ECI may use W-8ECI, subject to exceptions.
Using the wrong certificate can trigger follow-up documentation or a higher default withholding rate. Read our foreign withholding forms guide for the broader payer-documentation context.
What are the 5 types of Form W-8, and who uses each one?
The five W-8 forms separate foreign individuals, foreign entities, ECI claims, exempt foreign organizations, and intermediaries. For 2026 payer documentation, choose carefully in every case based on beneficial ownership, entity status, income type, and Chapter 3 or 4 rules rather than nationality alone.
The five forms cover different payees and purposes, so use the row that matches both the signer and the income.
| Form | Who files it | Individual or entity | Main purpose | May claim treaty benefits? |
|---|---|---|---|---|
| W-8BEN | Foreign beneficial owner | Individual | Foreign status; treaty claim for eligible income | Yes, if eligible |
| W-8BEN-E | Foreign beneficial owner | Entity | Foreign status, treaty claim, and chapter 4 classification | Yes, if eligible |
| W-8ECI | Foreign beneficial owner claiming ECI | Individual or entity | Certify that specified income is effectively connected with a US trade or business | Not as the form's main function |
| W-8EXP | Certain foreign governments, international organizations, central banks, and exempt organizations | Entity/organization | Claim qualifying foreign or exempt status | Generally no treaty claim through this form |
| W-8IMY | Intermediary, flow-through entity, or certain branches | Entity/intermediary | Identify intermediary or flow-through status and transmit owner documentation | Usually not for the intermediary itself |
The IRS requester instructions for the W-8 series explain which certificate fits each status. Do not guess between forms because one payment can be subject to different withholding rules depending on the documentation.
For ECI, compare ECI vs. FDAP income before choosing the certificate. Our Form W-8ECI guide covers the ECI form in detail.
The FATCA W8 and W9 forms serve different documentation roles. W-8BEN-E and W-8IMY can include detailed Chapter 4 classifications, while Form W-9 includes a FATCA exemption-code field for certain US payees.
The W8 BEN vs. W-9 distinction is still foreign person versus US person. The next chooser separates that status question from the ECI question.
W-8BEN vs. W-8BEN-E vs. W-8ECI: quick chooser
Choose W-8BEN for a foreign individual, W-8BEN-E for a foreign entity, and W-8ECI for a foreign beneficial owner claiming that specified income is ECI. That three-part screen works only after you first confirm the signer is not a US person who should use W-9.
The quick decision is individual, entity, then ECI – but ECI can override the ordinary W-8BEN or W-8BEN-E path.
| Individual | Entity | ECI check |
|---|---|---|
| Foreign beneficial owner, non-ECI payment: W-8BEN | Foreign beneficial owner, non-ECI payment: W-8BEN-E | Foreign beneficial owner claiming specified income is ECI: W-8ECI |
The following three checks help select the form:
- If the payee is a foreign individual and the income is not being certified as ECI, start with W-8BEN.
- If the payee is a foreign entity and the income is not being certified as ECI, review W-8BEN-E and its chapter 4 classification.
- If a foreign beneficial owner claims that specified income is ECI, review W-8ECI and any special withholding rule that applies.
Our W-8BEN-E guide for foreign entities explains the entity-side classification questions.
The W-8-versus-W-9 question is separate from the subtype question. If you are unsure whether income is ECI or whether you are a beneficial owner, use the comparison below before signing.
W-9 vs W-8 for ECI: which form applies when income is effectively connected
A foreign beneficial owner generally uses W-8ECI to certify that specified income is effectively connected with a US trade or business. A US person uses W-9 instead. Partnership ECI under section 1446(a) is a key exception because a foreign partner generally provides W-8BEN or W-8BEN-E.
The IRS Form W-8ECI page identifies W-8ECI as the certificate for a foreign person's ECI claim. Publication 515 (2026) explains the withholding treatment and special partnership rules.
The W9 vs W8 ECI decision should follow the following three branches:
- US person: Form W-9, even if the person has income from a US trade or business.
- Foreign beneficial owner claiming specified income is ECI: generally, Form W-8ECI.
- Foreign person receiving non-ECI US-source income: use the W-8 subtype that matches the payee and payment, such as W-8BEN or W-8BEN-E.
Important: US-connected income does not automatically mean Form W-9. W-9 certifies US-person status; W-8ECI certifies foreign status plus an ECI claim for the specified income.
A foreign partner allocated effectively connected taxable income under section 1446(a) generally gives the partnership a W-8BEN or W-8BEN-E, not a W-8ECI. A section 871(d) or 882(d) election can change that documentation rule.
W-9 vs. W-8: what are they, and what is the difference in tax status, withholding, and reporting?
The W-9 vs W8 comparison starts with tax status: W-9 identifies a US person, while W-8 certifies foreign status and may support treaty, ECI, exempt-status, or intermediary treatment. In 2026, missing documentation can trigger different withholding regimes, not one universal rate.
A resident versus nonresident alien analysis can decide the form for a noncitizen. The W-8 vs W-9 choice then follows the federal tax classification.
The main W-8 vs. W-9 form rule is status first: 24% backup withholding is a W-9-side rule for covered reportable payments, while 30% NRA withholding applies to specified foreign-person payments unless a lower or exempt rate applies.
| Item | Form W-9 | W-8 series |
|---|---|---|
| Tax status | US person | Foreign person or qualifying intermediary/status |
| Default withholding issue | 24% backup withholding on covered reportable payments when a trigger applies | Commonly 30% on specified US-source FDAP or other chapter 3/4 payments unless documentation supports another rate |
| Common downstream reporting | Form 1099 series, depending on payment | Form 1042-S for many reportable foreign-person payments |
| Who receives it | Requester/payer | Withholding agent/requester |
| Typical user | US citizen, resident alien, or domestic entity | Foreign individual, foreign entity, exempt foreign organization, or intermediary |
The difference between W-8 and W-9 is not where the signer lives. It is whether the signer is a US person and, for a foreign signer, what withholding certification fits the payment.
W-9 certifies a US person's TIN and status. W-8 certifies foreign status and, depending on the subtype, may document treaty benefits, ECI, chapter 4 status, or intermediary status.
The difference between the W8 and W9 tax forms also affects downstream reporting. A payer may use W-9 data for a Form 1099, while foreign-person payments commonly fall into Form 1042-S reporting.
A W8/W9 request can also arise under FATCA. See our guide to the FATCA code on Form W-9 for the US-person side of that documentation.
When do you use IRS Form W-9 or W-8?
Choose the payer certificate only after deciding whether the payee is a US person or foreign person. For a foreign person, check ECI before defaulting to W-8BEN or W-8BEN-E because the correct certificate can change with the payment and beneficial-owner status.
The following five if/then steps put the tax-status question first:
- If the payee is a US citizen, resident alien, or domestic entity, use Form W-9.
- If the payee is foreign, ask whether the payment is being certified as ECI before choosing a W-8 subtype.
- If a foreign individual is the beneficial owner of non-ECI income, W-8BEN commonly applies.
- If a foreign entity is the beneficial owner of non-ECI income, W-8BEN-E commonly applies.
- If the signer is an intermediary, flow-through entity, exempt organization, or other special-status payee, review W-8IMY or W-8EXP instead.
A W-9 or W-8 form may be requested during bank onboarding, investment-account opening, marketplace onboarding, or a client-vendor setup. The requester uses it to document status before applying its reporting and withholding rules.
A W8 or W9 IRS form request should not be answered by address alone. A US citizen in Germany still uses W-9, while a foreign individual outside the United States may use W-8BEN if that form fits the payment.
A W8 / W9 form is required for certain payer documentation workflows when the requester must establish the payee's status for information reporting or withholding. The exact requirement depends on the payment and governing reporting rule.
NOTE! A W-8 or W-9 tax form does not replace Form 1040, Form 1040-NR, Form 1065, or another annual return. It is documentation given to a requester.
US persons: when Form W-9 is the right form
A US person uses Form W-9 even while living abroad. In 2026, the March 2024 revision remains the current W-9, and residence in Lisbon, Tokyo, or Mexico City does not change US citizenship or resident-alien status for this certification.
The following four status examples belong on the W-9 side:
- US citizen living abroad.
- Lawful permanent resident, or green card holder, unless US tax residency has ended under applicable rules.
- Resident alien who meets the substantial presence test or another US-residency rule.
- Corporation, partnership, LLC, or other entity treated as a domestic US person for federal tax purposes.
A US citizen freelancing from Portugal still gives a US client Form W-9. The client's location and the freelancer's foreign address do not convert that US person into a W-8 signer.
Foreign persons: when to use a W-8 form instead
A foreign person generally uses the W-8 certificate that matches the payee and payment rather than Form W-9. In 2026, the choice can involve W-8BEN, W-8BEN-E, W-8ECI, W-8EXP, or W-8IMY, and personal-services rules can point to Form 8233 or W-4 instead.
The following four scenarios cover the main W-8 paths:
- Foreign individual beneficial owner with qualifying non-ECI income: review W-8BEN.
- Foreign entity beneficial owner: review W-8BEN-E and its chapter 4 classification.
- Foreign beneficial owner claiming specified income is ECI: review W-8ECI and its exceptions.
- Foreign intermediary or flow-through entity: review W-8IMY and the required owner documentation.
For W-8 or W-9 for a nonresident alien, the answer is normally a W-8 rather than a W-9, but the subtype depends on income and status. See how ECI tax rules affect foreign persons with a US trade or business.
Warning: A foreign person who signs a W-9 incorrectly is certifying US-person status. That can cause incorrect information reporting, withholding, and follow-up requests.
A foreign consultant who performs all services outside the United States may give a US client Form W-8BEN to document foreign status. If services are performed in the United States, sourcing and personal-services rules can require different documentation.
How to fill out Form W-9 and W-8 forms correctly
Complete the form that matches your status, then make the identity, classification, TIN, address, and signature fields consistent. For 2026 requests, the current W-9 is the March 2024 revision, while W-8 forms use their current IRS revisions and remain subject to change-in-circumstances rules.
For W-8/W-9 certification, identity and TIN data must match the person whose status is being certified. Our TIN guide explains SSNs, EINs, ITINs, and other federal identification numbers.
The first check is consistency: the legal name, classification, TIN, address, and signature should describe the same taxpayer.
| Checklist item | What to verify |
|---|---|
| Identity | Legal name matches the taxpayer whose status is certified |
| Tax classification | Individual, corporation, partnership, disregarded entity, or other status is correct |
| TIN | Correct type and number for the named taxpayer |
| Address | Current permanent or mailing address as the form requires |
| Signature and date | Certification is signed and dated when required |
The expat IRS tax form checklist can help separate payer documentation from forms attached to an annual return.
Forms W-8 and W-9 compliance depends on matching the form to the taxpayer before checking individual fields.
The field-level difference is that W-9 centers on a US person's TIN and classification, while W-8 forms add foreign-status, treaty, ECI, exempt-status, or intermediary questions.
| Field | W-9 | W-8 series |
|---|---|---|
| Name | US taxpayer/owner name under W-9 rules | Foreign beneficial owner, entity, intermediary, or other signer as required |
| Classification | Federal tax classification | Foreign entity, chapter 4, intermediary, or other status as applicable |
| TIN | SSN, EIN, or another permitted US TIN | Foreign TIN and/or US TIN when required |
| Address | Mailing address | Permanent residence or organization address, plus mailing address when applicable |
| Certification | US status and backup-withholding statements | Foreign status plus subtype-specific certifications |
The following three red flags cause repeated documentation problems:
- The legal name and TIN belong to different taxpayers.
- A required TIN or foreign TIN is missing without a valid exception.
- The signer uses the wrong W-8 subtype for the payment or status.
How to fill out Form W-9 correctly
Form W-9 has five fields that deserve a deliberate check: legal name, business name, federal tax classification, address, and TIN. On the March 2024 form, a sole proprietor or disregarded entity enters the owner's name on line 1 and the business or disregarded-entity name on line 2.
The following five field checks cover the main W-9 entries:
- Line 1: enter the name of the taxpayer whose TIN appears in Part I.
- Line 2: enter a business or disregarded-entity name if it differs from line 1.
- Line 3a: choose the federal tax classification for the taxpayer named on line 1.
- Lines 5 and 6: enter the address used for requester records.
- Part I and Part II: enter the correct TIN, then sign the required certifications.
For the official form, use the IRS Form W-9 PDF. A disregarded LLC does not automatically check the LLC box; the W-9 instructions tell it to reflect the tax classification of its owner.
Our foreign-owned single-member LLC guide explains why US entity and owner reporting can diverge.
A US citizen who performs freelance work from Spain still completes Form W-9 as a US person. The foreign work location does not change line 3a into a foreign classification.
How to fill out the W-8 series correctly
Complete a W-8 in four steps: select the correct version, enter the legal name and country information, complete the status or income certifications, and sign and date it. In 2026, the right subtype depends on the recipient and payment, not nationality alone.
The following four steps apply across the W-8 family:
- Select W-8BEN, W-8BEN-E, W-8ECI, W-8EXP, or W-8IMY based on the signer and payment.
- Enter the legal name, country, permanent address, and required TIN information.
- Complete treaty, ECI, chapter 4, exempt-status, or intermediary sections only when they apply.
- Sign and date the form, then give it to the requester rather than mailing it to the IRS.
Warning: An unsigned W-8 is not valid documentation, and an expired W-8 may no longer support the requested withholding treatment.
Common mistakes that trigger backup withholding or 30% withholding
Five documentation mistakes cause clear withholding problems: wrong form, missing TIN, expired W-8, inconsistent residency status, and unsigned certification. In 2026, 24% backup withholding and 30% NRA or Chapter 4 withholding are different regimes, so the fix must match the payment.
Name-and-TIN mismatches can generate payer notices. See why the IRS may say taxpayer information does not match.
The practical fix is to replace invalid documentation before the next payment whenever possible; 24% backup withholding and 30% foreign-person withholding do not operate under the same rules.
| Mistake | Fix |
|---|---|
| Wrong form | Confirm US or foreign status, then replace W-9 or select the correct W-8 subtype |
| Missing or incorrect TIN | Provide the TIN required for that form and payee |
| Expired W-8 | Give the requester a new valid W-8 before further payments |
| Inconsistent residency status | Resolve the green-card, substantial-presence, treaty, or other status issue before certifying |
| Unsigned certification | Sign and date the form when the form requires certification |
Documentation errors can overlap with other international reporting problems. Our guide to correcting common FBAR mistakes covers a separate filing system with different correction rules.
A 24% backup-withholding issue is not the same as a 30% W-8 documentation consequence. Do not describe either percentage as applying automatically to every payment.
A documentation problem can also reveal older US filing issues. If you live abroad and discover that required US tax returns or FBARs were missed in prior years, correcting the W-8 or W-9 does not by itself bring those filings up to date.
How long do W-8 and W-9 forms stay valid?
Form W-9 has no fixed expiration while its information remains correct. A W-8 generally runs through the last day of the third succeeding calendar year, but specific W-8 forms and documentary-evidence rules can provide indefinite or other validity periods until circumstances change.
A W-8 signed in 2026 is often valid through December 31, 2029, while W-9 remains usable until its underlying information changes.
| Form | General validity | Replace sooner when |
|---|---|---|
| W-9 | No fixed expiration | Name, TIN, classification, or other certified information changes |
| W-8BEN | Generally through the last day of the third succeeding calendar year; some foreign-status cases can be indefinite | Residence, treaty claim, or other certified fact changes |
| W-8BEN-E | Generally through the last day of the third succeeding calendar year; some foreign-status documentation can be indefinite | Entity, chapter 4, treaty, or ownership facts change |
| W-8ECI | Generally through the last day of the third succeeding calendar year | The income or ECI certification is no longer correct |
| W-8EXP | Generally through the last day of the third succeeding calendar year, unless a change in circumstances occurs | Exempt or foreign-government status changes |
| W-8IMY | Often indefinite for specified intermediary status, subject to change-in-circumstances and documentation rules | Intermediary status or underlying documentation changes |
The following three changes commonly require updated documentation:
- A person changes tax residence or becomes a US person.
- An entity changes classification, chapter 4 status, or beneficial ownership.
- The payment changes from non-ECI income to ECI, or the prior ECI certification no longer fits.
Keep the form and supporting records for as long as they matter to the payer or your return. Our guide to preserving tax and financial records explains broader record-retention considerations.
NOTE! Becoming a US person can also create separate reporting for foreign investments. Non-US mutual funds, ETFs, and similar holdings may need a PFIC review and Form 8621.
Do I send W-8 and W-9 to the IRS?
No. Form W-9 and the W-8 certificates are generally given to the requester or withholding agent, not mailed to the IRS. The requester keeps the documentation and may file a downstream information return, such as Form 1099 or Form 1042-S, depending on the payment.
The following three reasons explain why the forms stay with the requester:
- They document the payee's US or foreign status before or during the payment relationship.
- They support the payer's withholding decision and information-reporting classification.
- They remain in the payer's records so the payer can show why it applied a particular reporting or withholding treatment.
For forms and instructions, use the IRS forms and instructions portal. A W-8 or W-9 itself is not the annual information return that the payer sends to the IRS.
Foreign-person payments can lead to Form 1042-S reporting. Our Form 1042-S guide explains the recipient statement and reporting flow.
For 2025 Forms 1042-S due March 15, 2026, the IRS allowed IRIS or FIRE. For 2026 Forms 1042-S due March 15, 2027, IRIS is the required e-file intake system because FIRE is retiring for tax year 2026.
What to do if a bank, client, or marketplace asks for a W-8 or W-9
Handle the request in three steps: confirm tax status, complete the correct form, and submit it by the requester's deadline. In 2026, a missing W-9 can trigger 24% backup withholding, while missing W-8 documentation can trigger a 30% rate on specified foreign-person payments.
For W8 vs. W-9 for businesses, the same status rule applies to the payee. Foreign contractor reporting also depends on where services are performed and whether a US reporting rule applies.
The W-9/W-8 form requirements for US companies do not mean every vendor gets the same form. A US company must document the payee and payment under the applicable reporting and withholding rules.
Warning: A bank or platform may pause onboarding or payouts until it receives acceptable documentation. That operational deadline comes from the requester; it is not a universal IRS due date for Form W-8 or W-9.
1. Figure out your US tax status
Start with three status buckets: US person, foreign person, or dual-status/uncertain. For a noncitizen in 2025 or 2026, the green-card test and substantial presence test can create resident-alien status, while exempt-individual days, closer-connection rules, and treaties can change the result.
The following three checks establish the starting point:
- US citizen, green card holder, resident alien, or domestic entity: begin with W-9.
- Foreign person who is not a US person: begin with the W-8 family and then determine the subtype.
- Dual-status or uncertain case: resolve the residency period and any treaty position before signing.
The IRS nonresident alien filing interview can help determine whether a nonresident return is required. Form choice still depends on the specific payer relationship and payment.
Real-estate transactions use separate withholding rules. The IRS FIRPTA withholding interview addresses dispositions of US real property interests by nonresident aliens.
2. Complete the form accurately
Before submitting, match five items: legal name, address, citizenship or residency indicators, TIN information, and signature date. A single mismatch can make a certificate unreliable, cause a documentation request, or lead the payer to apply a presumption or withholding rule instead.
The following five fields should match your status:
- Legal name of the person or entity whose status is certified.
- Address required by that specific form.
- Citizenship, country of organization, residency, or chapter 4 indicators when required.
- US TIN and/or foreign TIN when the form requires it.
- Signature and date by the person authorized to certify the information.
The simplest field check is to compare identity, classification, TIN, and certification before the form leaves your hands.
| Check | W-9 | W-8 |
|---|---|---|
| Status | US person | Foreign person or qualifying intermediary/status |
| TIN | US TIN that matches the named taxpayer | Foreign TIN and/or US TIN when required |
| Classification | Federal tax classification | W-8 subtype plus any entity/chapter 4 status |
| Certification | US status and backup-withholding statements | Foreign status plus subtype-specific statements |
Before you submit: Check these three items again – the taxpayer name matches the TIN, the form matches the payee's status, and the signer has completed every required certification.
3. Submit the form on time
Give the form to the requester by its onboarding or payment deadline, because there is no single annual IRS due date for W-8 or W-9 submissions. Missing W-9 documentation can trigger 24% backup withholding, while missing W-8 documentation can trigger different rates based on the payment.
The following three submission actions reduce avoidable follow-up:
- Send the form before the first payment or by the requester's stated deadline.
- Replace the form when a change in circumstances makes prior information incorrect.
- If a form is rejected, ask which field or certification failed rather than sending the same version again.
A business may have separate year-end information-return deadlines. The IRS notes a January 31 deadline for certain employer wage statements and independent-contractor forms, but that does not create a January 31 W-8 or W-9 deadline for every payee.
If withholding creates a cash-flow problem, see our guide on what to do if you cannot pay tax on time. Backup-withholding name/TIN errors can also lead to CP2100 or CP2100A correction steps.
If your status changes after submission, give the requester new documentation promptly. Do not wait for the prior certificate to expire if it has already become inaccurate.
Quick reference: which form for which scenario
Once tax status is known, six common scenarios map to a likely starting form. The table is a quick reference for 2026 documentation, not a substitute for checking source-of-income, ECI, treaty, intermediary, or personal-services rules when those facts apply.
Use this table only after status is settled; a direct US client does not make foreign services US-source by itself.
| Scenario | Typical status | Starting form |
|---|---|---|
| US bank onboarding while living abroad | US citizen or resident alien | W-9 |
| US bank onboarding | Foreign individual | W-8BEN |
| Marketplace or payment platform | US person abroad | W-9 |
| Marketplace or payment platform | Foreign individual | W-8BEN |
| Direct US client | Foreign individual or foreign entity | W-8BEN or W-8BEN-E if appropriate after sourcing/status review |
| Specified ECI payment | Foreign beneficial owner claiming ECI | W-8ECI, subject to special rules |
This second W8/W9 checkpoint is about the payer workflow, not nationality alone. A W-8 or W-9 form request should be answered only after confirming who is being paid and what income the form covers.
Bottom line: W-9 for US persons, W-8 for foreign persons
For 2026 payer requests, the core rule still fits in two sentences: US persons use Form W-9, while foreign persons use the W-8 certificate that matches their status and payment. Living abroad does not by itself turn a US citizen or resident alien into a W-8 signer.
The main ECI exception is W-8ECI for a foreign beneficial owner claiming specified income is effectively connected with a US trade or business, subject to section 1446 and other special rules.
If the wrong form is caught early, give the requester corrected documentation. Whether prior withholding can be credited, refunded, or otherwise corrected depends on the payment, withholding regime, and return that applies.
FAQs about W-8 and W-9 forms
US citizens generally use Form W-9 because living abroad does not end US-person status.
A foreign individual may use W-8BEN to document foreign status, but services performed in the United States can require Form 8233, Form W-4, or other treatment depending on the facts.
No. W-8ECI is the general ECI certificate for a foreign beneficial owner, but partnership ECTI and other special rules can require different documentation.
Generally no. Give them to the requester or withholding agent, which keeps them and uses them for its withholding and information-reporting decisions.
Give the requester a corrected form promptly. Any withholding refund or credit depends on the tax and information-return rules for that payment.
W-9 has no fixed expiration while its information stays correct; many W-8 forms follow the third-succeeding-calendar-year rule, with important exceptions.
