Form W-9 for Freelancers: How to Fill It Out and Why Clients Hold Payment Without It
One page, seven lines and a signature — and the reason your first invoice from a new client is sitting unpaid
Short answer
A W-9 gives a client your legal name, tax classification and taxpayer ID number so they can file a Form 1099-NEC. The client keeps it on file — it is never sent to the IRS. Skip it or give a wrong TIN and the payer must withhold 24% of every payment.
Why every client asks for a W-9 before paying
A W-9 is not a tax return, a filing, or a submission. It is a one-page certification you hand to a business that intends to pay you, containing four things they need and nothing else: your legal name, your federal tax classification, your taxpayer identification number, and your signature swearing the number is correct.
The client wants it for a mundane reason. If they pay you enough during the year, they have to file a Form 1099-NEC reporting what they paid, and that form requires a name and TIN that match IRS records. Getting that pair wrong generates a mismatch notice for them months later. Collecting the W-9 up front is how they avoid it.
The dollar figure moved recently. For payments made in 2026, the 1099-NEC and 1099-MISC filing threshold is $2,000, up from the $600 that had stood since the 1950s — see our guide to the 2026 1099 threshold change. That has not loosened anyone's W-9 policy, and it should not loosen yours. Nobody knows at the first invoice whether a client relationship will finish the year at $900 or $19,000, and the backup withholding rules that make a missing TIN expensive operate independently of the reporting threshold entirely.
So the practical sequence at most companies is: contract signed, W-9 received, vendor record created, invoice payable. Miss the third step and your invoice sits in a queue nobody is looking at. This is the single most common reason a first payment from a new client is late, and it is entirely within your control to prevent by sending the form unprompted with your first invoice.
If you are on the paying side of this — subcontracting work to a designer, an editor, an assistant — the same logic applies in reverse: collect the form before the first payment, every time. The Agreedly generator drafts a W-9 request letter that explains why the form is needed, sets a deadline, and asks for secure delivery instead of an SSN in a reply-all.
The form, line by line
The current version is Form W-9 (Rev. March 2024). If you have a saved PDF from a few years ago, replace it — the March 2024 revision renumbered the classification line to 3a and added a new line 3b, and some client portals reject the older layout.
- Line 1 — Name. Required, and it must match the name on your income tax return. Never leave it blank. If you are a sole proprietor or a single-member disregarded entity, this line is your own name, not your business name, even if every invoice you have ever sent says otherwise.
- Line 2 — Business name / disregarded entity name. Your DBA, trade name or LLC name goes here if it differs from line 1. Optional, and cosmetic to the IRS, but it helps the client match your 1099 to their vendor record.
- Line 3a — Federal tax classification. Seven checkboxes, exactly one of which you check: individual/sole proprietor, C corporation, S corporation, partnership, trust/estate, LLC (with a letter for how the LLC is taxed), or other. The table below covers who checks what.
- Line 3b — Foreign partners, owners or beneficiaries. New on this revision, and blank for the overwhelming majority of freelancers. It applies only if you checked partnership or trust/estate, or checked LLC and entered "P", and the entity has direct or indirect foreign partners, owners or beneficiaries. A US person filling this out for themselves leaves it alone.
- Line 4 — Exemptions. Two code boxes, for exempt payee status and FATCA reporting. The instructions are unusually direct here: individuals, including sole proprietors, are not exempt from backup withholding. If you are a freelancer, leave line 4 empty.
- Lines 5 and 6 — Address. This is where the client mails your 1099, so use an address you will still be reading mail at in February. If the address differs from the one the requester already has on file, the instructions say to write "NEW" at the top of line 5.
- Line 7 — Account numbers. Optional. Fill it in if the client asked for a vendor number; otherwise skip it.
- Part I — TIN. One box for an SSN, one for an EIN. Fill in exactly one. More on which below.
- Part II — Certification. Four statements signed under penalties of perjury: the TIN is correct, you are not subject to backup withholding, you are a US person, and any FATCA code entered is correct. Read item 2. If the IRS has notified you that you are currently subject to backup withholding for underreporting interest and dividends, you are supposed to cross it out before signing.
A small piece of trivia that surprises people: for nonemployee compensation the instructions say you are not technically required to sign the certification, only to provide a correct TIN. Do not use this as a negotiating position. Every accounts payable department on earth will reject an unsigned W-9, and the certification is the part that protects you from backup withholding.
| If you are… | Line 1 / Line 2 | Check on line 3a | Typically receives a 1099-NEC? |
|---|---|---|---|
| A freelancer with no entity (sole proprietor) | Line 1: your legal name. Line 2: DBA, if any. | Individual/sole proprietor | Yes |
| A single-member LLC, not incorporated (disregarded entity) | Line 1: the owner's name. Line 2: the LLC name. | The owner's classification — for an individual owner, individual/sole proprietor. Not the LLC box. | Yes |
| A multi-member LLC taxed as a partnership | Line 1: the LLC's legal name. Line 2: DBA, if any. | LLC, entering P | Yes |
| An LLC or corporation with an S corporation election | Line 1: the entity's legal name. | LLC entering S, or S corporation if incorporated | Generally no — see the exceptions below |
| A C corporation (or LLC taxed as one) | Line 1: the entity's legal name. | C corporation, or LLC entering C | Generally no — see the exceptions below |
The corporate exemption is where people overreach. Payments to a corporation, including an LLC treated as a C or S corporation, are generally not reportable on a 1099 — but the exceptions are real and specific: attorney fees, gross proceeds paid to an attorney, and medical and health care payments are reportable even when the payee is a corporation. Incorporating your law practice does not stop the 1099s from arriving.
The single-member LLC row is the one that generates the most incorrect forms. Forming an LLC feels like it should change what you write on line 1. It does not. A disregarded entity has no separate tax identity, so the IRS wants the owner's name on line 1 and the owner's classification on line 3a, with the LLC name relegated to line 2. Checking the LLC box because you have an LLC is the classic mistake, and it is precisely the mismatch that produces a notice for your client a year later.
SSN or EIN: which number goes in Part I
For a sole proprietor who has an EIN, the IRS instructions are permissive — you may enter either the SSN or the EIN. Given a genuine choice, take the EIN.
- Exposure. Every client you invoice ends up holding a copy of this form, usually in an email thread, a shared drive and a vendor portal. Ten clients over five years is fifty copies of your Social Security number in systems you do not control. An EIN is a business identifier; a compromised one is a bad afternoon rather than a bad year.
- Cost and speed. An EIN is free directly from the IRS, the online application issues the number immediately, and there is no filing requirement attached to simply having one. The IRS says plainly that you never have to pay a fee for an EIN — any site charging you $70 to "file" one is reselling a free government form.
- The catch. Name-and-TIN matching is unforgiving. Whichever number you use, line 1 must be the name associated with it in IRS records. If you registered the EIN under a name that differs from what appears on your return, you have manufactured the exact mismatch that triggers a B-notice.
- Entity rules override preference. A single-member disregarded LLC enters the owner's SSN or EIN, not the LLC's. An LLC classified as a corporation or partnership enters the entity's EIN. Only the unincorporated sole proprietor actually gets to choose.
If you do not have a TIN yet and someone needs a W-9 today, the instructions allow you to write "Applied For" in the TIN space, sign and date the form, and hand it over. Be clear-eyed about what that buys you: the 60-day grace period applies to interest, dividends and certain readily tradable instruments, not to nonemployee compensation. For freelance work, backup withholding applies to payments until you furnish the number.
Backup withholding: what 24% actually means
Backup withholding is the enforcement mechanism sitting behind the entire W-9 exercise, and it is the reason clients are stubborn about the form. The rate is 24% of the reportable payment, withheld by the payer and remitted to the IRS.
The two triggers that matter to a freelancer are a missing or incorrect taxpayer identification number and an IRS B-notice — the notice a payer receives when the name and TIN combination on an information return does not match IRS records, which obliges them to solicit a corrected W-9 from you and begin withholding if you do not supply one. There is a separate trigger for taxpayers the IRS has notified about underreported interest and dividend income, which is the item you would cross out in Part II.
What it feels like in practice: you invoice $5,000, the client pays $3,800, and $1,200 goes to the IRS in your name. The money is not lost. It is credited against your tax liability like any other withholding and shows up in the federal income tax withheld box of your 1099. But it is your working capital gone for months, on top of the quarterly estimated payments you are probably already making — see quarterly estimated taxes for freelancers for how those interact, and our free 2026 self-employment tax calculator if you want the number for your own income.
Fixing it is straightforward and entirely on you: furnish the correct TIN to the payer. Withholding stops prospectively once they have a valid, certified number; it is not refunded by the client, because they have already sent it to the IRS. You recover it when you file. If the trigger was underreported interest or dividends, you have to resolve the underlying issue with the IRS first.
The penalties for playing games here are modest in dollars and unpleasant in kind: $50 for each failure to furnish a correct TIN when required, unless due to reasonable cause and not willful neglect; $500 for a false statement with no reasonable basis that results in no backup withholding; and criminal penalties, including fines and imprisonment, for willfully falsifying certifications. The certification is signed under penalties of perjury. Treat it that way.

Analyze your contract now →When to send an updated W-9
A W-9 does not expire. It stays good until something on it becomes wrong, at which point sending a fresh one is a two-minute job that prevents a mismatched 1099 next January. Send a new form when:
- Your name changes. Marriage, divorce, a legal name change. The instructions require a new W-9 when the name for the account changes, and the name on line 1 must match what the Social Security Administration or the IRS has for your TIN — so update them first, then the clients.
- Your TIN changes. You got an EIN and want to stop handing out your SSN, or your entity got a new number. Also required by the instructions.
- Your entity or classification changes. You formed an LLC, elected S corporation treatment, or converted. Line 3a is now wrong, and line 3a is what the client uses to decide whether to file a 1099 at all.
- Your address changes. Not strictly a certification issue, but line 5 is the mailing address for your 1099. Send the update and write "NEW" at the top of line 5.
- You stop qualifying for an exemption you claimed. Rare for freelancers, since individuals are not exempt payees to begin with, but the instructions require updating a payer if you claimed exempt status and no longer qualify.
A useful habit: when you renegotiate or renew a contract, re-send the W-9 in the same email. It costs nothing, and it quietly resets the client's file to current without either of you having to remember which version they have.
W-9 vs W-4 vs W-8BEN
Three forms, three different relationships, and clients confuse them constantly. If a client sends you a W-4, they think you are an employee — which is either an administrative error or a classification problem worth resolving before you sign anything.
| Form | Who fills it out | What it is for | Where it goes |
|---|---|---|---|
| Form W-9 | US persons — citizens, resident aliens, and US entities — being paid as contractors or vendors | Certifies your name, tax classification and TIN so the payer can file information returns such as a 1099-NEC. No withholding results from a correct W-9. | To the requester. Kept on file, never sent to the IRS. |
| Form W-4 | Employees | Tells an employer how much federal income tax to withhold from each paycheck. Presupposes an employment relationship, not a contractor one. | To the employer. Kept on file. |
| Form W-8BEN | Foreign individuals who are the beneficial owners of US-source income | Certifies non-US status and claims any applicable tax treaty benefit against US withholding. There are related W-8 variants for foreign entities. | To the withholding agent or payer. Kept on file. |
And the pairing people search for most: W-9 versus 1099. They are two ends of the same process, not alternatives. You give the client a W-9 at the start of the relationship; the client uses it to send you and the IRS a 1099-NEC after the year ends. You never fill out a 1099 for your own work, and the client never files your W-9.
How to spot a fake W-9 request
A completed W-9 is a compact identity theft kit: legal name, address, and either an SSN or an EIN, signed. It is a popular phishing target for exactly that reason, and the tells are consistent.
- The IRS is not asking. The IRS does not email, text or direct-message you to request a W-9, and it never initiates contact that way to ask for personal or financial information. A W-9 request that appears to come from the IRS is fraudulent, full stop. Legitimate requests come from a business that is about to pay you.
- Verify the payer relationship, not the email. Ask yourself whether this company actually owes you money. A W-9 request from an organization you have never invoiced has no legitimate basis, no matter how convincing the letterhead is.
- Check the domain, not the display name. Reply-to addresses on a free mail provider, or a domain one character off the client's real one, are the standard mechanics of a business email compromise. When the request arrives mid-project from a "new accounts payable contact", confirm it through a channel you already had.
- Be suspicious of urgency and scope creep. Real onboarding does not need your bank credentials, a photo of your driver's license and a W-9 within the hour. A W-9 asks for a TIN. It does not ask for a bank password.
- Never email an unencrypted SSN. Use the client's vendor portal if they have one. If they do not, send a password-protected PDF and give the password by phone or text, or use a secure file transfer link. An EIN instead of an SSN downgrades this whole problem from serious to routine.
If a request looks fraudulent, do not reply to it. Suspicious tax-related emails can be forwarded to the IRS at phishing@irs.gov, and the client whose name was spoofed generally wants to know.
Frequently asked questions
Do I still need to give a client a W-9 if they'll pay me under $2,000?
Almost certainly yes, and you should not argue about it. The $2,000 figure is the 1099-NEC filing threshold for payments made in 2026, and it is a question the client answers in January, not in March when they onboard you. Neither of you knows at the first invoice whether the year's total will cross it, and a payer who has no valid taxpayer identification number on file can be required to apply 24% backup withholding regardless of the amount. Most accounts payable systems will simply not release a payment until a W-9 exists.
Should I use my SSN or an EIN on a W-9?
If you are a sole proprietor with an EIN, the IRS instructions let you enter either one, and an EIN is the better habit. It keeps your Social Security number out of the files, inboxes and vendor portals of every client you have ever invoiced, which meaningfully reduces your identity theft exposure. An EIN is free directly from the IRS, the online application issues the number immediately, and no third-party site should ever charge you for one. The tradeoff is small: the name on line 1 must still match what the IRS has on file for that number, so a mismatch between your EIN registration and your return is the one way this goes wrong.
What happens if I refuse to fill out a W-9?
The client does not lose the right to pay you, but they gain an obligation to withhold. Without a certified taxpayer identification number, the payer is generally required to withhold 24% of reportable payments and remit it to the IRS. In practice most clients avoid the bookkeeping entirely by holding the payment until the form arrives. The IRS also imposes a $50 penalty for each failure to furnish a correct TIN when required, unless the failure is due to reasonable cause and not willful neglect, and a $500 civil penalty for a false statement with no reasonable basis that results in no backup withholding.
Does an LLC get a 1099?
It depends on how the LLC is taxed, not on the letters after its name. An LLC treated as a disregarded entity or as a partnership is generally reportable, so it receives a 1099-NEC for services once the payer crosses the filing threshold. An LLC that has elected C corporation or S corporation treatment is generally exempt from 1099 reporting, with real exceptions: attorney fees, gross proceeds paid to an attorney, and medical and health care payments are reportable even when the payee is a corporation. This is exactly why line 3a matters. The client reads that box to decide whether a form is required.
Is the W-9 sent to the IRS?
No. The form says so on its face: give it to the requester, do not send it to the IRS. The payer keeps it in their records and uses the information to prepare information returns such as Form 1099-NEC, which is what actually reaches the IRS. That is also why the security of the form is a private matter between you and the client rather than something the IRS mediates, and why a requester who misuses a taxpayer identification number can face civil and criminal penalties.
How long is a W-9 valid, and when do I need to send a new one?
A W-9 has no expiration date. It stays valid until the information on it stops being correct. Send an updated form when your legal name changes, when your taxpayer identification number changes, or when your entity or tax classification changes, such as forming an LLC or making an S corporation election. IRS instructions specifically require a new Form W-9 when the name or TIN for the account changes. Address changes do not invalidate the form, but you should still tell the client, because line 5 is the address they will mail your 1099 to. Many companies also re-request W-9s annually as a routine control, which is not a red flag by itself.
The short version
Fill out the March 2024 revision. Put your legal name on line 1 even if you have an LLC, check the one box on line 3a that matches how you are actually taxed, use an EIN instead of your SSN if you can, leave line 4 empty, and sign it. Send it with your first invoice rather than waiting to be chased. The whole exercise exists so a client can file a 1099 with a name and number that match IRS records — and so that 24% of your money stays in your account instead of the Treasury's.
