Formulário W-9 2026

O que é o Formulário W-9?

The Form W-9 is an IRS tax form used in the United States.

This form is an official document used by third parties to request someone’s tax details. It’s also known as a Request for Taxpayer Identification Number and Certification.

Every business and company in the US has to provide a W-9 Form to any self-employed workers they hire.

The worker must then fill it out and send it back to the employer. It’s not necessary to send the completed form to the IRS—the employer uses the information provided on the W-9 form to submit another document called the Form 1099.

Para que serve o Formulário W-9?

The purpose of the Form W-9 is to confirm that the employee is responsible for their own income tax as well as their Social Security and Medicare payments.

Another function of Form W-9 is to avoid backup withholding. When you complete a W-9 you can certify that you’re not subject to backup withholding, which stops the employer from withholding taxes to be sent to the government and allows you to be paid in full.
