How to Fill Out a Form W-9 as a Freelancer

You just landed a new freelance client, sent over your contract, and requested your deposit. But before they can pay you, they ask for a "W-9."

Don't panic. The W-9 is one of the most common—and easiest—tax forms you will encounter as a freelancer. Here is a comprehensive guide to what it is and how to fill it out perfectly on your first try.

What is a W-9?

Form W-9 (officially titled "Request for Taxpayer Identification Number and Certification") is an IRS form that businesses use to gather information from independent contractors (freelancers) they hire.

Your client needs this form because if they pay you more than $600 during the tax year, the IRS requires them to report those payments on a Form 1099-NEC. They cannot issue the 1099 without your correct name, address, and Taxpayer Identification Number (TIN).

Note: The W-9 is not sent to the IRS. It stays in your client's files.

Step-by-Step Instructions

Line 1: Name

Enter your full legal name as it appears on your personal tax return. Even if you operate under a cool business name ("Super Design Studio"), if you are a sole proprietor or a single-member LLC, your personal legal name goes here.

Line 2: Business Name / Disregarded Entity Name

If you have a registered "Doing Business As" (DBA) name, or if you are a single-member LLC, you put that business name on Line 2. If you just freelance under your own legal name, leave this line blank.

Line 3: Federal Tax Classification

This is where most people get tripped up. You must check exactly one box:

• Individual/sole proprietor or single-member LLC: Check this box if you have not formally incorporated, OR if you are an LLC with only one owner that has not elected to be taxed as an S-Corp or C-Corp. (90% of freelancers check this box).
• C Corporation or S Corporation: Only check these if you have officially filed paperwork with the IRS to be taxed as a corporation.
• Partnership: Check this if your business is a multi-member LLC or legal partnership.

Line 4: Exemptions

As an individual freelancer, you can almost always leave this box blank. Exemptions typically apply to specific corporate entities or financial institutions.

Lines 5 & 6: Address

Enter the mailing address where you will receive your tax forms (like your 1099s) at the end of the year. Make sure this is current!

Part I: Taxpayer Identification Number (TIN)

You must provide the TIN that matches the name you put on Line 1.

• If you are a sole proprietor, enter your Social Security Number (SSN).
• If you are a single-member LLC, the IRS prefers you enter your SSN, but you can also enter your Employer Identification Number (EIN) if you have one.
• If you are an S-Corp or multi-member LLC, you must use your EIN.

Part II: Certification

Read the certification statements. By signing, you are confirming under penalties of perjury that the TIN is correct, you are a US person, and you are not subject to backup withholding. Sign and date the form.

Security Best Practices

Because a W-9 contains your Social Security Number and home address, it is a highly sensitive document.

• Never email an unencrypted W-9. Standard email is not secure.
• Use a secure file-sharing service (like a password-protected Dropbox link, Google Drive link, or a secure client portal).
• If you must email it, encrypt the PDF with a password and text the password to your client separately.
