How to Fill Out a W-9 If You Don’t Have a Business

To fill out a W-9 when you don’t have a business, put your legal name on Line 1, leave Line 2 blank, check the “Individual/sole proprietor or single-member LLC” box on Line 3, skip Line 4, enter your mailing address on Lines 5 and 6, write your Social Security number in Part I, then sign and date Part II. The whole form is one page, and most people finish it in under five minutes. What takes longer is understanding what happens after you hand it in, because a W-9 sets you up to receive a 1099 and to owe taxes no one is withholding for you.

What to Have Ready

Two things: your Social Security card (or your Individual Taxpayer Identification Number if you don’t have an SSN) and your most recent federal tax return. The name on your W-9 has to match your tax return, and your tax return has to match Social Security Administration records. Any mismatch can trigger an IRS notice to the payer and eventually backup withholding on your payments.¹

If you’ve changed your last name but haven’t updated the SSA yet, the IRS instructions say to enter your first name, the last name on your Social Security card, and then your new last name. Update the SSA as soon as you can.²

Most individuals without a business use their Social Security number on the W-9. Resident aliens who aren’t eligible for an SSN use an ITIN instead.³ The W-9 is only for U.S. persons (U.S. citizens and resident aliens). Nonresident aliens use Form W-8BEN instead. Dual citizens who hold U.S. citizenship still use the W-9, even if they live abroad.²

Line by Line

Line 1: Your Name

Enter your full legal name exactly as it appears on your federal tax return. Include suffixes (Jr., Sr., III) if they appear on your Social Security card. This line cannot be left blank.²

Line 2: Business Name

Leave this blank. Line 2 is for a business name, trade name, or disregarded entity name. If you’re operating as an individual with no formal business structure, there’s nothing to put here. The one exception: if you have a single-member LLC treated as a disregarded entity for tax purposes, your personal name goes on Line 1 and the LLC’s name goes on Line 2.²

Line 3: Federal Tax Classification

Check the first box: “Individual/sole proprietor or single-member LLC.” That’s the correct classification for anyone earning income without a separate business entity. Don’t check the boxes for C Corporation, S Corporation, Partnership, or Trust; those apply to formally organized structures.²

Line 4: Exemptions

Skip it. The two fields here are an exempt payee code and a FATCA reporting code. Individuals are generally not exempt from backup withholding, and the FATCA code only applies to accounts held outside the United States by certain foreign financial institutions. Domestic account, individual payee: both stay blank.²

Lines 5 and 6: Address

Enter the address where you receive mail. Year-end tax documents will be sent here, so use a stable address. Street address on Line 5; city, state, and ZIP on Line 6.

Part I: Taxpayer Identification Number

Enter your nine-digit Social Security number (or ITIN) in the boxes provided. Check every digit. An incorrect number can trigger backup withholding, where the payer deducts 24% of your future payments and sends it to the IRS until you provide a corrected form.⁵

Signing and Sending It Back

Part II is the certification. By signing and dating, you’re certifying under penalty of perjury that your taxpayer identification number is correct and that you’re not subject to backup withholding. Knowingly making false statements on a W-9 is a felony carrying fines up to $100,000 and up to three years in prison.⁶

A handwritten signature is standard. Electronic signatures may be accepted, but confirm with the requester before you send a digital one.

The completed form goes to the person or company that requested it. Never to the IRS. The payer keeps it on file to generate accurate information returns at year-end.²

Because the form contains your Social Security number, treat it like any other sensitive financial document. Don’t send it as an unencrypted email attachment. Better options: hand it over in person, use an encrypted file transfer service, send a password-protected PDF with the password communicated separately, or use the requester’s secure portal if they have one.

Why You’re Being Asked Before Any Money Changes Hands

Payers often request a W-9 before they’ve paid you anything. People sometimes push back because they’ve heard about a “$600 threshold,” but that number is the trigger for filing a Form 1099-NEC at year-end, not for collecting a W-9. A company that expects it might pay you $600 or more over the calendar year has every reason to collect your information upfront.⁷ Requests also come from banks, brokerages, and anyone who pays you interest, dividends, or certain other reportable income.⁴

If You Refuse or Get Something Wrong

If you don’t provide a W-9 at all, the payer is required to begin backup withholding at 24% on any reportable payments they make to you.⁸ That money is pulled from what you’d otherwise receive and sent to the IRS. You can recover it when you file your return, but your cash flow takes the hit in the meantime.

The same 24% kicks in if the name and TIN on your W-9 don’t match IRS records. The IRS sends the payer a CP2100 or CP2100A notice, the payer sends you a “B notice” asking you to correct the problem, and if you don’t respond within the specified timeframe, backup withholding starts on future payments until you provide a corrected W-9.¹

Keep a copy of every W-9 you submit. If a payer’s 1099 shows the wrong name or TIN, having your copy makes it easy to prove what you originally provided.

What Comes After: the 1099 and Your Tax Return

The main downstream effect of submitting a W-9 is that you’ll receive a Form 1099-NEC (for nonemployee compensation) or Form 1099-MISC (for other types of payments) early the following year. Payers must furnish these statements to you by January 31.⁷

You report this income on Schedule C (Profit or Loss from Business), filed with your personal return. Even without a formal business, the IRS treats individual freelance and contractor earnings as sole proprietorship income. Schedule C is also where you deduct legitimate expenses (supplies, software, travel, home office costs), which reduce the amount you’re taxed on.⁹

The IRS receives a copy of every 1099 issued in your name. If the income on your return doesn’t match those 1099s, expect an automated notice. Report your 1099 income even if you think the amount is wrong, and resolve any discrepancy with the payer rather than quietly omitting it.

Self-Employment Tax and Quarterly Payments

This is the part most first-time freelancers don’t see coming. Income reported on a 1099 isn’t just subject to regular income tax. You also owe self-employment tax for Social Security and Medicare. The combined rate is 15.3% (12.4% for Social Security, 2.9% for Medicare).¹⁰ An employer normally pays half of that; when you’re self-employed, you pay both halves.

The Social Security portion applies to net earnings up to $184,500 in 2026.¹¹ The Medicare portion applies to all net earnings with no cap. Above $200,000 for single filers, an additional 0.9% Medicare surtax kicks in.¹⁰ Self-employment tax is calculated on Schedule SE, filed with your 1040.

There’s no automatic withholding on 1099 income. The IRS expects quarterly estimated payments covering both your income tax and self-employment tax. The four deadlines for the 2026 tax year:

First quarter: April 15, 2026
Second quarter: June 15, 2026
Third quarter: September 15, 2026
Fourth quarter: January 15, 2027

You can skip the January 15 payment if you file your 2026 return and pay the full balance by February 1, 2027.¹²

Missing these deadlines triggers an underpayment penalty. You can generally avoid it by paying at least 90% of the current year’s tax liability, or 100% of the prior year’s tax (110% if your prior-year AGI was over $150,000). If this is your first year with freelance income and you had no tax liability last year, the prior-year safe harbor works in your favor. Plan ahead, because the second year won’t be as forgiving.¹³
