Forms W-8 and W-9 in the USA: the essential guide

Reading time: 4 minutes

Expanding into the US market often represents a major opportunity for non-US companies looking to grow and succeed globally. It can provide access to one of the world’s largest economies.

For non-US companies venturing into the vast and lucrative US market, it is essential to understand and comply with US tax regulations and legal requirements. Two forms play an essential role in this process: the W-9 and W-8 forms.

Forms W-8 and W-9 are essential for companies and individuals who do business with companies in the United States, particularly from the point of view of tax compliance.

Have you ever been asked to complete a W-9 or W-8 form? We’ll explain what these forms are for.

What is the W-9 form?

Form W-9 is an official document from the Internal Revenue Service (IRS), the US tax authority that collects income tax and various taxes, including employment, corporate and estate taxes. It is required from individuals or companies supplying goods or services. Here is what the W-9 form generally contains:

  • The legal name of the company.
  • The Tax Identification Number (TIN), which is an identification number allocated to taxpayers by the tax authorities.

What is the purpose of the W-9 form?

The purpose of Form W-9 is to collect the tax information needed to meet U.S. income tax reporting obligations. Its primary purpose is to collect identifying information about a person or entity, such as:

  • TIN information: The primary purpose of Form W-9 is to collect the recipient’s TIN. This ensures identification of the person or company and correct reporting to the IRS.
  • Information Reporting : U.S. entities use the information provided on Form W-9 to prepare information reports, making it easier to document payments to non-U.S. entities.

Practical tip: If a US company asks you to complete a W-9 form, provide accurate information, including your TIN. Failure to do so may result in a withholding tax, where a percentage of your income will be withheld for tax purposes.

What is form W-8?

Form W-8 is a document used by US non-residents to certify their alien status and establish their eligibility for withholding tax exemptions or reductions on payments they receive from the United States.

The W-8 series includes various forms tailored to different types of foreign entities. Commonly used forms include W-8BEN, W-8BEN-E and W-8ECI, each responding to specific circumstances based on the foreign status of the recipient and the nature of the income. Here are some details of the different forms:

  • W-8BEN: Used by non-U.S. individuals to certify their non-resident status in order to avoid double taxation or to benefit from reduced withholding rates under a tax treaty.
  • W-8BEN-E: Used by foreign entities to certify their non-resident status in order to avoid double taxation or to benefit from reduced withholding rates under a tax treaty.
  • W-8ECI: Used by non-U.S. persons (individuals or entities) to declare that certain income relates to trade or business conducted in the United States and is therefore taxable.

What is the purpose of form W-8?

Form W-8 allows nonresident aliens to certify their tax status and claim tax benefits on income received in the United States, including for :

  • Claiming tax treaty benefits: Foreign companies can use W-8 forms to declare their foreign status, allowing them to claim reduced tax rates or exemptions under applicable tax treaties between the U.S. and their home country.
  • Avoiding withholding tax: Completing a Form W-8 helps foreign companies avoid withholding tax on their U.S.-source income.

Practical information: To take advantage of the provisions of tax treaties, it is crucial for non-US entities to complete the correct Form W-8 that corresponds to their status and the type of income received from US sources.
