As a human resources or finance manager of a mid to large-sized company, managing an international team and streamlining global hiring, payroll, and compliance processes can be challenging. One important tax form you need to be familiar with when working with contractors or vendors in the United States is the W-9 form.

What Is a W-9 Form?

IRS Form W-9, officially titled “Request for Taxpayer Identification Number and Certification”, is used by businesses to collect important tax information from independent contractors and other non-employees they hire and pay over $600 in a tax year. The key details a W-9 gathers include:

• Name
• Business name (if different from name)
• Federal tax classification (individual/sole proprietor, partnership, corporation, etc.)
• Address
• Taxpayer Identification Number (TIN) – either a Social Security Number (SSN) or Employer Identification Number (EIN)

By providing this information and signing the W-9, the contractor is certifying that the TIN provided is correct and agreeing that the hiring company will not withhold taxes since they are not an employee. The company then uses the W-9 details to generate a 1099 form to report the contractor’s earnings to the IRS.

When to Request and Use a W-9 Form

As a best practice, businesses should require any U.S. contractor, consultant, or vendor they expect to pay more than $600 in a year to complete a W-9 before beginning the work engagement. This ensures you have all the necessary tax details upfront. Other scenarios that may require a W-9 include:

• Financial institutions collecting customer information for tax reporting on interest, dividends, etc.
• Real estate transactions
• Debt cancellation

While there is no official deadline, it’s important to obtain a W-9 as early as possible, since you will need the information to file a 1099 form for the contractor, which is due by January 31. Penalties for late or incorrect 1099 filings can range from $50 to $550 per form.

How Contractors Fill Out a W-9

Completing a W-9 is a straightforward process. The contractor needs to:

1. Provide their name as shown on their income tax return
2. Write their business name, if different from above
3. Check the appropriate box for their federal tax classification
4. Provide their full address
5. List their TIN (SSN or EIN)
6. Sign and date the form to certify the information is correct

If parts of the W-9 do not apply, such as exemption codes, the contractor can leave those lines blank. Once complete, they return the W-9 to the requesting company, not the IRS.

Tips for Managing W-9s in Your Global Business

To efficiently handle W-9 forms as part of your international hiring and payroll processes:

1. Clearly communicate the need for a W-9 upfront and include it as part of your onboarding for any U.S. contractor
2. Use secure methods like encrypted file sharing to collect and store completed W-9s, protecting sensitive data
3. Keep W-9s on file for at least 3 years after the contractor’s final 1099 filing, in case of an audit
4. Regularly review and update W-9s if contractor information changes
5. Consider using global employment solutions that help automate and streamline tax form collection and filings across different countries

The Bottom Line

The W-9 form plays a critical role in ensuring tax compliance when hiring contractors and vendors in the United States. By understanding the purpose of the W-9, when to request it, and establishing best practices for collection and management, you can avoid costly penalties and create a smoother hiring and payroll process for your international team.

Staying on top of tax requirements across multiple countries is complex. Working with a knowledgeable global employment partner can give you peace of mind and allow you to focus on growing your business.
