The brief
What is a W-9 form?
In short
A W-9 is the IRS form a US person or business gives to a client who is paying them, confirming their legal name and taxpayer identification number. The client keeps it and uses it to issue a 1099 at year end. It is never sent to the IRS by the person signing it.
Why do you need a W-9 form?
A client who has no W-9 from you must apply backup withholding, which is 24 percent of the payment held back and sent to the IRS. Most simply stop paying instead until the form arrives.
Getting it wrong causes the mismatch that surfaces months later. A name or number that does not agree with IRS records triggers a notice to your client, and it is your invoice that gets held while it is sorted out.
Who needs a W-9 form?
- US companies and contractors invoicing other US businesses
- Anyone being onboarded as a vendor or a supplier
- Businesses that will receive a 1099 for the year
- Companies asked for tax details before a payment is released
On your own, or with Summit
- Name and number. We complete it against what the IRS holds for your company.
- If they disagree. We fix the mismatch and reissue the form.
When you'll be asked for one
Most US payers won't release a payment until they have a W-9 on file.
The good news: once it's done correctly, you can reuse the same W-9 with any payer who asks. We get the details right so it sails through without a back-and-forth.
Common moments
- A US client onboards you as a vendor or contractor
- A marketplace or platform needs it before paying out
- A payment processor or bank requests it for your account
- A partner needs to report payments they make to you

Questions
Asked on the way up.
Who needs a W-9?
Anyone a US company or platform is going to pay and report on. It works for both businesses and individuals.
Does filling out a W-9 cost me anything in tax?
No. It simply gives your payer the information they need to pay you and report it. It's not a tax return and it doesn't create a tax bill on its own.
Can I reuse the same W-9?
Yes. Once it's filled out correctly, you can send the same form to any payer who asks, until your information changes.
What is the difference between a W-9 and a W-4?
A W-4 is for employees: it tells an employer how much tax to withhold from a salary. A W-9 is for everyone else, contractors, vendors and businesses, and withholds nothing. It simply gives the payer the name and tax number they need to issue a 1099 at year end.
Do I send the W-9 to the IRS?
No. The W-9 goes to whoever is paying you, and they keep it on file. The IRS only sees the information later, on the 1099 your client issues. Sending it to the IRS yourself does nothing and delays the payment you are waiting on.
What happens if I refuse to give a client a W-9?
The client must apply backup withholding, which is 24 percent of every payment held back and sent to the IRS. In practice most clients simply stop paying until the form arrives, so refusing costs you the invoice rather than protecting anything.
Do I need a W-9 if I invoice through a marketplace?
Usually yes. Platforms that pay you are payers like any other, and most collect a W-9 during onboarding so they can issue a 1099 later. It is the most common reason a first payout sits on hold.
What name goes on the W-9 for a single-member LLC?
The name has to match what the IRS holds for the tax number you give. For a single-member LLC that usually means the owner's name on the first line and the LLC's name on the second, which is the mismatch that most often triggers a notice to your client.
Does signing a W-9 make me an employee?
No. A W-9 is the form used precisely because you are not an employee: no tax is withheld, no payroll is run, and you receive a 1099 rather than a W-2. It says nothing about the working relationship beyond that.
