W-9s and 1099s for Freelancers: What They Are and When They Apply

A new client says they can't pay you until you send a W-9. Then in late January a 1099 shows up in your mailbox, or doesn't, and you're not sure which is worse. Here's what the paperwork actually does, who sends what to whom, and what to check when a form looks wrong. None of it is complicated once you see the flow.

The W-9: You Fill It Out, the Client Files It Away

A W-9 is a one page form where you give a client your legal name, your business name if you use one, your tax classification, and your taxpayer identification number. The client doesn't send it to the IRS. They keep it on file so that in January they can prepare a 1099 reporting what they paid you. A W-9 request is standard onboarding at any business that runs real books, not a sign of trouble. Fill it out, sign it, and return it promptly, because plenty of accounting departments won't release a first payment without one on file.

One detail worth acting on: the form asks for your Social Security number or an Employer Identification Number. An EIN is free from the IRS, takes a few minutes to get online, and keeps your SSN out of a dozen clients' shared drives. If you freelance regularly, get one and use it everywhere.

The 1099-NEC: The Client Tells the IRS What They Paid You

When a business pays you $600 or more for services in a calendar year, it's generally required to file a 1099-NEC reporting the total, with a copy to you and a copy to the IRS, due by January 31. Payments to corporations are mostly exempt, which is why some LLCs taxed as corporations never receive them. Card and payment app transactions travel a different road entirely: the payment processor reports those on a 1099-K, and the threshold rules for that form have changed several times in recent years, so check the current figure instead of trusting an old blog post.

No 1099? You Still Owe Tax on the Income

The 1099 is an information form, not a permission slip. A client who paid you $480 files nothing, and that $480 is still taxable. A client who forgot to file doesn't erase the $5,000 they paid you. Your own records are the source of truth, which is one more argument for invoicing everything and keeping the PDFs organized by year. If you build your invoices and log each one as it goes out, your January totals are already sitting there waiting, and no missing form can surprise you.

When the 1099 Doesn't Match Your Records

Compare every 1099 against your own invoice log before you file. Mismatches usually come from timing: you invoiced in December, the client paid in January, and their form counts the payment year rather than your invoice year. That's not an error, since 1099s report payments made. Real errors happen too, like reimbursed expenses lumped into the total or a plain typo. Ask the payer for a corrected form. If they won't cooperate, report the correct income based on your records and keep the evidence of your request.

Keep the Flow Tidy Year Round

• Save a copy of every W-9 you send, with the date and the client it went to
• If your name, address, or entity type changes, send updated W-9s without waiting to be asked
• In January, reconcile each 1099 against that client's invoice totals
• Chase missing 1099s in early February if you want the paper, but don't panic over one that never comes. Your reporting doesn't depend on it

Two caveats deserve their own sentences. This is general US federal education, and state rules layer on top of it, with other countries running entirely different systems. And your choice of sole proprietor, LLC, or S corp changes some of this paperwork, so walk your specific setup past a local accountant once. It's a short conversation that prevents expensive guessing, and if you're brand new to billing, the freelancer first invoice checklist covers the rest of the setup.
