What is a W-9?

A W-9 (Request for Taxpayer Identification Number and Certification) is an IRS form that US businesses use to collect your tax information before paying you. It captures your name, address, and Tax Identification Number (TIN) - either your Social Security Number (SSN) or Employer Identification Number (EIN).

Why do clients ask for a W-9?

When a US business pays a contractor or freelancer more than $600 in a calendar year, they are required by the IRS to report that payment. To do this, they need your tax information. The W-9 is how they collect it. Once they have your W-9, they will send you a 1099-NEC form after the year ends showing what they paid you, which you use to file your taxes.

It is a standard tax compliance process. Getting asked for a W-9 is not unusual or a sign of distrust - it just means the client is following IRS rules.

What information goes on a W-9?

✓
Name: Your legal name as it appears on your tax return.
✓
Business name: If you operate under a different business name, enter it here. Leave blank if not applicable.
✓
Tax classification: Individual/sole proprietor for most freelancers. LLC or S-Corp if your business is structured that way.
✓
Address: Your mailing address.
✓
TIN: Your Social Security Number if filing as an individual, or your EIN if you have one.
✓
Signature and date: Certifying that the information is accurate.

What if I am not in the US?

If you are a non-US freelancer working with US clients, you do not fill out a W-9. Instead, the client may ask you for a W-8BEN (for individuals) or W-8BEN-E (for entities). This certifies that you are a foreign person and not subject to US tax withholding. Check with a tax professional in your country for specifics.

What happens if I do not provide a W-9?

The client may withhold 24% of your payment as backup withholding and send it to the IRS. That money is not lost - you can claim it back when you file your taxes - but it does affect your immediate cash flow. It is almost always easier to just fill out the form.
