W-9 for Freelancers: How to Fill It Out and When a Client Can Ask

At FreelanceAtlas, we help freelancers handle the paperwork that comes with getting paid. This guide covers which name goes on which line, the tax classification boxes, line 3b, SSN versus a free EIN, the certification and backup withholding, when a client can ask, how to send the form safely, the 1099 that may follow, and the W-8BEN that non-US freelancers use instead, with two email templates. If you are still choosing a structure, read Sole Proprietor vs LLC for Freelancers: Which Business Structure Do You Actually Need?, and if you are unsure you count as a contractor, start with Independent Contractor vs Employee: How Classification Is Decided.

This article is general information, not tax advice. The right entries on your W-9 depend on how your business is set up and taxed, and the rules change, so check with a CPA or enrolled agent before you rely on it for your own situation.

What Form W-9 Is For, and What It Is Not

The official title is “Request for Taxpayer Identification Number and Certification.” The IRS’s About Form W-9 page says to use it “to provide your correct Taxpayer Identification Number (TIN) to the person who is required to file an information return with the IRS.” For freelancers, that return is usually Form 1099-NEC, which reports nonemployee compensation.

As of September 2026, the current version is the March 2024 revision, and the IRS page lists no newer developments. Check the date under “Form W-9” in the top left corner. If a client uses its own version, the form itself says you “must use the requester’s form if it is substantially similar to this Form W-9.”

• It never goes to the IRS. The top right corner reads: “Give form to the requester. Do not send to the IRS.”
• It does not decide whether you are an employee. The IRS’s 1099-NEC and independent contractor FAQ says classification turns on behavioral control, financial control and the “relationship of the parties.”
• It is only for US persons. The form says to “Use Form W-9 only if you are a U.S. person (including a resident alien).” A US citizen living abroad still uses it. Non-US freelancers use a W-8 form, covered at the end.

Lines 1 and 2: Which Name Goes Where

Line 1 can never be blank, and the form spells out the rule: “For a sole proprietor or disregarded entity, enter the owner’s name on line 1, and enter the business/disregarded entity’s name on line 2.” The IRS’s Instructions for the Requester of Form W-9 say this is needed “for proper processing.”

If You Are a Sole Proprietor

Enter your individual name “as shown on your Form 1040” on line 1, and any business, trade or “doing business as” (DBA) name on line 2. If you work under your own name, leave line 2 blank. If you changed your last name without telling the Social Security Administration, the form says to enter “your first name, the last name as shown on your social security card, and your new last name,” because the name and number must match IRS records.

If You Own a Single-Member LLC

A single-member LLC that has not elected corporate tax treatment is a “disregarded entity.” The form says “The name of the owner entered on line 1 should never be a disregarded entity.” Your personal name goes on line 1, and “Your Studio LLC” goes on line 2.

That feels backwards to many owners, but the IRS’s single-member LLC page explains that “the LLC’s activities should be reflected on its owner’s federal tax return,” including Schedule C. If your LLC has two or more members, or filed Form 8832 or 2553 to be taxed as a corporation, it is not disregarded, and its own name goes on line 1.

Line 3a: The Federal Tax Classification Boxes

Line 3a has seven boxes, and you check exactly one. The March 2024 revision clarified how LLCs use it: “An LLC that is a disregarded entity should check the appropriate box for the tax classification of its owner.” Every other LLC checks the LLC box and enters C, S or P. For common freelance setups:

The table follows the form’s own line 3a chart. The one error to avoid: checking the LLC box for a single-member LLC with default tax status. The requester instructions say the IRS “clarified” exactly this point in the 2024 revision.

Lines 3b Through 7: The Ones Most Freelancers Leave Blank

Line 3b: Foreign Partners, Owners or Beneficiaries

Line 3b is new in the March 2024 revision. It applies only if you checked Partnership or Trust/estate, or LLC with P, and you are giving the form “to a partnership, trust, or estate in which you have an ownership interest.” Then you check it if you have any foreign partners, owners or beneficiaries. A sole proprietor or single-member LLC sending a W-9 to a client leaves it blank.

Line 4, Exemptions. Leave it blank. The form says “Generally, individuals (including sole proprietors) are not exempt from backup withholding,” and the FATCA code concerns accounts held outside the United States.

Lines 5 and 6, Address. This is “where the requester of this Form W-9 will mail your information returns.” If it differs from the address the client has on file, write “NEW” at the top.

Line 7 and the requester box. Both are optional.

Part I: Social Security Number or EIN?

The TIN in Part I “must match the name given on line 1 to avoid backup withholding.” The form allows:

• Sole proprietor: “If you are a sole proprietor and you have an EIN, you may enter either your SSN or EIN.” A footnote in the form’s name-and-number chart adds that “the IRS encourages you to use your SSN.”
• Single-member LLC with default tax status: the owner’s SSN or EIN. The IRS single-member LLC page says the W-9 “should provide the owner’s SSN or EIN, not the LLC’s EIN,” so an EIN the LLC got for a bank account or payroll does not go here.
• LLC taxed as a corporation or partnership: the LLC’s own EIN.
• Resident alien not eligible for an SSN: your IRS individual taxpayer identification number (ITIN).

You may still prefer an EIN, for one reason: exposure. The W-9’s identity theft section tells you to “Protect your SSN,” and the IRS tells clients to keep each W-9 for four years. An EIN means one fewer copy of your Social Security number in other companies’ files. Whichever you choose, use it consistently, so each 1099 matches your return.

How to Get an EIN Free From the IRS

The IRS’s EIN page is blunt: “You never have to pay a fee for an EIN,” and “Beware of websites that charge for an EIN.” If approved, the IRS will “issue your EIN immediately online.” As of September 2026:

• Your principal place of business must be in the US or US territories, and you need the responsible party’s SSN or ITIN.
• You finish in one session; the application “expires after 15 minutes of inactivity.”
• You can get only one EIN per responsible party per day.
• The tool runs Monday to Friday from 6 a.m. to 1 a.m. the next day, Saturday from 6 a.m. to 9 p.m., and Sunday from 6 p.m. to midnight, Eastern Time.

If you cannot apply online, the EIN page links to applying by phone, fax or mail, and the W-9 points to the paper Form SS-4.

What “Applied For” Means for Freelancers

Without a TIN, you may write “Applied For” in Part I, sign and send the form. Do not count on it to protect your pay. The 60-day grace period covers only interest, dividends and certain readily tradable instruments. The requester instructions say “Any other reportable payment, such as nonemployee compensation, is subject to backup withholding immediately, even if the payee has applied for and is awaiting a TIN.” Get the EIN first.

Part II: The Certification and Backup Withholding

By signing, you certify under penalties of perjury that the TIN is correct, that you are not subject to backup withholding, that you are a US person, and that any FATCA code is correct. Strictly, for payments to a nonemployee for services, the form says you “do not have to sign the certification unless you have been notified that you have previously given an incorrect TIN.” But “You may be requested to sign by the withholding agent,” and many clients do ask. Signing a correct form costs nothing.

Backup withholding is why clients care. Payers “must under certain conditions withhold and pay to the IRS 24% of such payments,” and the form’s list includes “nonemployee pay” and “payments made in settlement of payment card and third-party network transactions.” It applies if you do not furnish your TIN, do not certify it when required, or the IRS tells the client your TIN is wrong. The IRS’s backup withholding page says the fix includes “providing the correct TIN to the payer,” and that you claim any amount withheld on your return “for the year you received the income.”

In cash terms: say a client owes you $3,000 in 2026 and has no valid TIN from you. At 24 percent, it sends $720 to the IRS and pays you $2,280. You recover the $720 only as a credit when you file.

The new threshold matters here. The IRS’s Instructions for Forms 1099-MISC and 1099-NEC say that for tax years beginning after 2025, the minimum for reporting certain payments “and/or perform backup withholding on those payments increased to $2,000.” An IRS video script on the new law is plain: “beginning in 2026, annual payments below $2,000 are not treated as reportable payments and would not necessitate backup withholding by the payer.”

Penalties run both ways. The form lists $50 for each failure to furnish your correct TIN, “unless your failure is due to reasonable cause and not to willful neglect,” and $500 for a false statement with no reasonable basis that results in no backup withholding. A requester who misuses TINs “may be subject to civil and criminal penalties.”

When a Client Can Ask, and Why It Is Before the First Payment

Any business that may file an information return about you can ask, and the IRS expects it to ask early. Its page on forms for independent contractors says “the first step is to have the contractor complete Form W-9,” and that the W-9 “should be kept in your files for four years.”

The timing is about money. The same page says a business “must withhold 24%” from reportable nonemployee compensation if a US contractor “has not provided their taxpayer identification number (TIN) in the manner required.” A client that pays first and collects the W-9 later takes a risk, so the request usually arrives with the contract or before the first invoice is paid. Keep a filled-in copy ready to date and sign.

• Freelance platforms. On Upwork, the W-9 goes to Upwork, not each client. Its tax help page mentions the setting you choose “when you fill out your Form W-9,” and says it does not send Forms 1099-MISC or 1099-NEC, “and neither do your clients.”
• Changes. The form says “you must furnish a new Form W-9 if the name or TIN changes for the account.” If you elect S corporation status or change the name or number on file, send each client an updated form.
• Requests from people who are not paying you. A W-9 request with no contract, invoice or payment attached is a warning sign. The form says “The IRS does not initiate contacts with taxpayers via emails,” so an email “from the IRS” asking for your W-9 is fake. More patterns are in Freelance Job Scams: 9 Patterns to Spot Before You Lose Money.

To make it routine, add a line to your agreement saying you will provide a signed W-9 through a secure channel before the first invoice. The FreelanceAtlas contract generator can help you draft it.

How to Send Your W-9 Safely

A completed W-9 puts your name, address and SSN or EIN on one page. The Federal Trade Commission’s guide Protecting Personal Information tells businesses: “Regular email is not a secure method for sending sensitive data.” It adds: “The better practice is to encrypt any transmission that contains information that could be used by fraudsters or identity thieves.” Hold your own data to the same standard. Safer options, in rough order:

1. The client’s vendor portal. The IRS lets requesters “establish a system for payees and payees’ agents to submit Forms W-9 electronically,” ending with an electronic signature “under penalties of perjury.”
2. A secure e-signature request from the client, so the form never sits in a plain email thread.
3. An encrypted, expiring file link from storage you control, with the password shared by phone or text, never in the same email.
4. Fax or mail. The IRS instructions mention fax by name.

Verify every request through a channel you already trust, such as the phone number in your contract. Never paste your SSN into a chat window. If you think your number has been exposed, the W-9 points to the IRS Identity Theft Hotline at 800-908-4490 or Form 14039, and says to forward suspected IRS impersonation emails to phishing@irs.gov.

When a client asks you to “just email it,” this reply keeps things friendly:

Subject: W-9 for [your legal name or business name]

Hi [Client name],

Thank you for the onboarding details. My signed Form W-9 (Rev. March 2024) is ready. Because it includes my taxpayer identification number, I would prefer not to send it as a regular email attachment.

Could you send me a link to your vendor portal or a secure upload page? If you do not have one, I can send an encrypted link that expires in 7 days and give you the password by phone.

For your vendor record, the form lists [your legal name] on line 1, [business name or “blank”] on line 2, and [Individual/sole proprietor] on line 3a. Please issue payments and any 1099 to that name.

Thank you,
[Your name]

When a request looks off, send this before you share anything:

Hi [Name],

Happy to provide a W-9 once we have a signed agreement and a first invoice scheduled. Could you confirm the company’s legal name, the project it relates to, and who in accounts payable will receive the form? I will then send it through your vendor portal or a secure link.

Thank you,
[Your name]

What Happens Next: The 1099 Your Client May File

The W-9 feeds a 1099. Under the current IRS 1099-MISC and 1099-NEC instructions, a business files Form 1099-NEC for each person “to whom you have paid at least $2,000” for services during 2026. The IRS 1099-NEC FAQ shows both figures: “$600 ($2,000 for payments made after December 31, 2025).” The $2,000 amount “may be adjusted for inflation beginning in calendar year 2027.” Our guide to 1099-NEC vs 1099-K: Which Tax Forms Freelancers Get in 2026 covers which forms arrive and how to reconcile them.

• Deadline. Clients must furnish your copy by January 31. For 2026 payments, January 31, 2027 is a Sunday, and the instructions move weekend due dates to the next business day, so look for it by Monday, February 1, 2027.
• Card and app payments. Payments by “credit card or payment card” and “third-party network transactions” go on Form 1099-K from the payment settlement entity, not on a 1099-NEC.
• Corporations. Payments to a corporation, including an LLC taxed as a C or S corporation, are generally exempt, with exceptions such as legal services.
• Mismatches. If your name and TIN do not match IRS records, the IRS requester instructions say the client “may have to send a ‘B’ notice to the payee to solicit another TIN.” Answer it quickly.

None of this changes what you owe. The IRS video script reminds payees that payments below the threshold “are still taxable business income.” The step-by-step is in How to Report Freelance Income When You Did Not Get a 1099, and running client money through a business bank account makes the year-end match between invoices, deposits and 1099s far easier.

Non-US Freelancers: Give a W-8BEN Instead

If you are not a US person, do not fill out a W-9. The form says: “If you are a nonresident alien or a foreign entity, give the requester the appropriate completed Form W-8 or Form 8233.” For an individual, that is usually Form W-8BEN. Its instructions, revised October 2021, set the boundaries:

• It is for “a nonresident alien who is the beneficial owner of an amount subject to withholding.” A US citizen abroad or a resident alien uses the W-9, and a foreign company uses Form W-8BEN-E.
• Give it to the payer “before the payment is made to you.” Otherwise “the withholding agent may have to withhold at the 30% rate,” or at the backup withholding rate.
• It generally stays valid until “the last day of the third succeeding calendar year.” One signed on September 15, 2026 would run through December 31, 2029, unless your circumstances change.

For freelancers working entirely outside the US, where the work happens is the key. The IRS’s source of income page says compensation “for services performed in the United States” is generally US source, and its page on foreign source income says such income “paid to a nonresident alien is normally not subject to U.S. tax under either chapter 3 or 4.” The W-8BEN documents that you are foreign; Upwork, for example, asks non-US freelancers for “a Form W-8BEN or Form W-8BEN-E” and reminds them they answer to the tax laws where they live. The payment side is in How to Get Paid as an International Freelancer: Wise, Payoneer, and the Real Costs.

Conclusion

A W-9 is a short form with three traps: whose name goes on line 1, which box an LLC checks, and whose number goes in Part I. Get those right and the form works quietly. Your client can report what it pays you, you avoid 24 percent backup withholding, and the 1099 that arrives next year matches your return.

Do this next. Download the March 2024 form from IRS.gov and fill in a master copy using the table above. Decide between your SSN and a free EIN, and if you want the EIN, get it before your next client asks. Date and sign the form only when a verified client requests it, and send it through a portal, e-signature request or encrypted link instead of a plain email. Then make a folder for the 1099s that should arrive by February 1, 2027.

Key Takeaways

• Form W-9 (Rev. March 2024) gives a US client your name, tax classification, address and TIN, and it goes to the client, never to the IRS.
• Sole proprietors and owners of a default single-member LLC put their own name on line 1, any business name on line 2, and check Individual/sole proprietor on line 3a.
• A disregarded single-member LLC lists the owner’s SSN or EIN in Part I, and the IRS says the W-9 should not carry the LLC’s own EIN.
• An EIN is free and issued online on approval; the IRS says “You never have to pay a fee for an EIN” and warns against sites that charge.
• Without a valid TIN, a client must backup withhold 24 percent of reportable payments, and from 2026, payments below $2,000 a year are not reportable for 1099-NEC or backup withholding.
• Non-US freelancers give Form W-8BEN instead, before payment, and it generally stays valid through the last day of the third calendar year after signing.

Frequently Asked Questions

Is it safe to give a client my Social Security number on a W-9?

It is a legitimate request from a real client, but how you send it matters. The FTC tells businesses that regular email is not a secure method for sending sensitive data, so use a vendor portal, a secure e-signature request, an encrypted link or fax. Sole proprietors may enter an EIN instead of an SSN. Always confirm the request through a channel you already trust.

Should a single-member LLC use its own EIN on a W-9?

Not if the LLC has default tax status. The IRS says a W-9 from a disregarded LLC owned by an individual “should provide the owner’s SSN or EIN, not the LLC’s EIN.” Put your name on line 1, the LLC’s name on line 2, and check Individual/sole proprietor. An LLC taxed as an S or C corporation uses its own name and EIN instead.

What happens if I do not send a client a W-9?

The client may have to withhold 24 percent of reportable payments as backup withholding, which you recover only as a credit when you file. The W-9 also lists a $50 penalty for each failure to furnish your correct TIN without reasonable cause. From 2026, payments under $2,000 a year from one client are not reportable payments, so backup withholding should not apply below that level.

Can I write “Applied For” while I wait for my EIN?

You can, but it does not delay backup withholding on freelance pay. IRS instructions say nonemployee compensation “is subject to backup withholding immediately, even if the payee has applied for and is awaiting a TIN.” The 60-day grace period covers only interest, dividends and certain readily tradable instruments. Since the IRS online tool issues an EIN on approval, get the number first.

I live outside the US. Do I fill out a W-9?

Only if you are a US citizen or resident alien, who use the W-9 even while living abroad. A nonresident alien individual gives the payer Form W-8BEN instead, and a foreign company uses Form W-8BEN-E. Provide it before you are paid, because without it the payer may withhold at 30 percent or the backup withholding rate.
