W-9 Best Practices Every Business Should Follow

W-9 Best Practices every Business should follow

Hi everyone, I wanted to share some helpful information from Erin Turco at EVT Consulting regarding W-9 best practices:

As we move deeper into the year, this is a great time to revisit one of the simplest ways to stay compliant and avoid January headaches: consistent W‑9 collection. Missing or outdated W‑9s are one of the most common issues we see during 1099 season, and a few small habits can make a big difference.

Why W‑9s Matter 

A completed Form W‑9 gives you the legal name, business classification, address, and tax ID you’re required to have on file before paying a contractor or vendor who may need a 1099. When this information is missing or incorrect, it can lead to filing delays, rejected forms, or the need for corrected 1099s later.

Best Practices to Follow All Year :

• Collect a W‑9 before issuing the first payment. Make this part of your onboarding process for any contractor or vendor. 

• Do not pay vendors who refuse to provide a W‑9. The IRS requires backup withholding if a vendor won’t furnish their tax ID. 

• Request updated W‑9s when information changes. New addresses, name changes, or entity changes all require a new form. 

• Store W‑9s securely. These forms contain sensitive information and should be kept in a secure digital or physical file. 

• Review your vendor list quarterly. This helps you catch missing forms long before year‑end.

Common Issues We See :

• Vendors paid throughout the year with no W‑9 on file 

• Incorrect legal names or outdated EINs 

• Contractors switching from sole proprietor to LLC without notifying the business 

• Clients waiting until January to request forms, when vendors are harder to reach.

A Quick Reminder About 1099s

 If you pay a non‑employee individual or unincorporated business $2000 or more for services during 2026, you may need to issue a 1099‑NEC. 

If you don’t have a W‑9, you are still required to file using whatever information you have—and issue a corrected form later if the vendor finally provides their details.

Want help tightening up your process? 

If you’d like support setting up a clean W‑9 workflow, organizing your vendor files, or preparing for 1099 season long before January, Erin would be happy to help. Strong bookkeeping systems make compliance easier and keep your year‑end stress low.
