How to fill out form W-9
When and Why You Fill Out a W-9
A Form W 9 is completed to provide your taxpayer identification number (such as your Social Security Number or EIN) to a business or financial institution. They use this information to properly report payments to the IRS, typically on a Form 1099.
If you live outside the U.S., a W 9 may also be used by financial institutions to report your account information to U.S. authorities.
Common Examples
• Freelancer or contractor:
You work for a U.S. company as an independent contractor — they ask for a W 9 so they can issue you a 1099-NEC at year-end.
• Service provider:
You provide services (consulting, marketing, design, etc.) and expect to be paid $600+ — the business requests a W 9 for IRS reporting.
• Financial accounts (including abroad):
A bank or investment firm requests a W 9 to confirm you are a U.S. person and to report your income or account details to the U.S.
• Real estate or other transactions:
You receive certain payments (like rent or settlement proceeds), and the payer needs your W 9 to file the appropriate 1099 form.
