To get a W-9, download the current PDF free from the IRS at irs.gov/pub/irs-pdf/fw9.pdf, fill in your name, tax classification, address, and taxpayer identification number, sign it, and send it back to the business that asked for it. Knowing how to get a W-9 and complete it correctly matters because the form is what businesses use to collect your taxpayer ID before paying you as an independent contractor or other non-employee, and to file information returns like Form 1099-NEC at year’s end.1Internal Revenue Service. About Form W-9, Request for Taxpayer Identification Number and Certification If your SSN or EIN is handy, the whole thing takes a few minutes.

Make Sure W-9 Is the Right Form
The W-9 is for U.S. citizens, resident aliens, and U.S. entities such as LLCs, partnerships, and corporations being paid as independent contractors or other non-employees.4Internal Revenue Service. Forms and Associated Taxes for Independent Contractors Two other forms are commonly confused with it:
- If the company hired you as an employee rather than a contractor, you fill out a Form W-4 instead, so taxes can be withheld from your paycheck.
- If you are a nonresident alien, you generally use Form W-8BEN.5Internal Revenue Service. Instructions for Form W-8BEN
Foreign nationals living in the United States who meet the IRS substantial presence test or hold a green card are treated as U.S. residents for tax purposes and use the W-9.6Internal Revenue Service. Substantial Presence Test If you originally gave a payer a W-8BEN and later became a U.S. resident alien, you have 30 days to notify the payer and send a new W-9.5Internal Revenue Service. Instructions for Form W-8BEN
What to Have Ready Before You Start
Pull these together before opening the PDF:
- Your legal name, exactly as it appears on your federal tax return.
- Your business name or DBA, if different from your legal name.
- Your federal tax classification: sole proprietor, LLC (and how it’s taxed), C corporation, S corporation, partnership, or trust/estate.
- Your taxpayer identification number: Social Security Number (SSN), Individual Taxpayer Identification Number (ITIN), or Employer Identification Number (EIN).
- Your current mailing address, where you want the year-end 1099 sent.
Most individuals use their SSN. Resident aliens who cannot get an SSN use an ITIN.7Internal Revenue Service. Instructions for the Requester of Form W-9 (Rev. March 2024) Businesses typically use an EIN. Federal law requires you to furnish this number.8Office of the Law Revision Counsel. 26 USC 6109 – Identifying Numbers
Filling Out Each Line
Lines 1 and 2: Names
Line 1 is your legal name, matching your tax return. Sole proprietors put their individual name here, not the business name. Line 2 is for a business name, trade name, or DBA that differs from Line 1.2Internal Revenue Service. Form W-9 (Rev. March 2024)
Single-member LLC owners trip on this often. The IRS treats a single-member LLC as a disregarded entity, so the owner’s name goes on Line 1 and the LLC’s name goes on Line 2, not the other way around.7Internal Revenue Service. Instructions for the Requester of Form W-9 (Rev. March 2024)
Line 3: Federal Tax Classification
Check one box only: individual/sole proprietor or single-member LLC; C corporation; S corporation; partnership; trust/estate; or LLC with a letter (C, S, or P) indicating how it’s taxed.2Internal Revenue Service. Form W-9 (Rev. March 2024) This choice affects whether the payer has to issue a 1099. Payments to corporations generally are not 1099-reportable, while payments of $600 or more to sole proprietors and partnerships are.9Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC (04/2025)
Line 4: Exemption Codes
Line 4 has two optional fields: a backup withholding exemption code and a FATCA reporting exemption code. Most individual freelancers and sole proprietors leave both blank. The codes apply to specific entities such as corporations, government agencies, tax-exempt organizations, banks, and broker-dealers.7Internal Revenue Service. Instructions for the Requester of Form W-9 (Rev. March 2024) If you’re unsure, leaving the fields blank simply means normal rules apply.
Lines 5 and 6: Address
Enter your current street address, city, state, and ZIP. This is where the payer will mail your 1099. An error here can mean a missing 1099 at tax time.
Part I: Taxpayer Identification Number
Enter your SSN, ITIN, or EIN. The number has to match the name on Line 1. A name/number mismatch can trigger an IRS notice to the payer and lead to backup withholding on future payments.2Internal Revenue Service. Form W-9 (Rev. March 2024) If you recently changed your name, update it with the Social Security Administration first.
Part II: Sign and Date
Your signature certifies, under penalty of perjury, that your TIN is correct, that you are not subject to backup withholding (unless the IRS has told you otherwise), that you are a U.S. person, and that any FATCA code you entered is correct.2Internal Revenue Service. Form W-9 (Rev. March 2024) The civil penalty for a false statement that lets you avoid backup withholding is $500.10Office of the Law Revision Counsel. 26 USC 6682 – False Information With Respect to Withholding Willful falsification can bring criminal penalties, including fines and imprisonment.
Returning the Completed Form
Send the form to the business or person who asked for it. Never send a W-9 to the IRS.2Internal Revenue Service. Form W-9 (Rev. March 2024) Common routes are a secure portal upload, fax, or physical mail. Electronic signatures are valid when the requester’s system captures the same perjury certification as the paper form.3Internal Revenue Service. Instructions for the Requester of Form W-9 (03/2024)
Treat the finished form like the sensitive document it is. If you’re sending it by email, use encryption or a password-protected PDF. A requester who discloses or misuses your identification number in violation of federal law faces civil and criminal penalties.2Internal Revenue Service. Form W-9 (Rev. March 2024) Keep a copy so you know which businesses hold your data.
What Happens If You Don’t Return One
If you don’t return a completed W-9, the payer must begin backup withholding at 24% on your payments.11Office of the Law Revision Counsel. 26 USC 3406 – Backup Withholding For non-employee compensation, backup withholding kicks in immediately, with no grace period.3Internal Revenue Service. Instructions for the Requester of Form W-9 (03/2024) A quarter of every check goes to the IRS on your behalf.
You can also receive a “B-notice” from the payer if your name and TIN don’t match or if a number is missing. Two rounds are possible:12Internal Revenue Service. Backup Withholding “B” Program
- On a first B-notice, a corrected, properly signed W-9 fixes it.
- On a second B-notice, you must also provide a copy of your Social Security card or an IRS Letter 147C verifying your name and EIN.
Backup withholding is not lost money. You can claim it as a credit on your annual return. But losing 24% of your cash flow until then is a serious hit, so returning the form promptly protects you.
When to Send an Updated W-9
A W-9 has no formal expiration date. Send a fresh one to any payer holding your information whenever something changes:2Internal Revenue Service. Form W-9 (Rev. March 2024)
- Your name changes, for example after marriage, divorce, or a legal name change.
- Your TIN changes, such as switching from your SSN to a new EIN for your business.
- Your business structure changes, such as a sole proprietorship becoming an LLC, or a C corporation electing S status.
- An exemption you previously claimed no longer applies.
