Catering vendor won't provide W-9 form - no tax information available for 1099 reporting

This is a pretty common issue with smaller vendors, unfortunately. Since you've already paid them, you're in a bit of a bind, but you still have some options: First, document everything. Save all emails where you requested the W-9 and their response asking for additional money. This creates a paper trail showing you attempted to comply with tax requirements. The IRS does have a process for this situation called "backup withholding" - but that's meant to be applied before payment. Since you've already paid the full amount, that ship has sailed. You could file Form 8809 to get an extension for filing your 1099s, which gives you more time to resolve this. Then continue trying to get the vendor to comply by explaining that you're legally required to report this payment and that refusing to provide a W-9 doesn't exempt them from taxes. As a last resort, you can file the 1099-NEC with incomplete information, noting that the vendor refused to provide their details. Include as much information as you have (name, phone, email). The IRS may penalize the vendor, not you, if you can show you made reasonable efforts to obtain the information.

I went through a similar nightmare last year with a photographer I hired for my business events. After weeks of unanswered emails about getting their W-9, I found this company called taxr.ai (https://taxr.ai) that was a total game-changer for me. They specialize in these exact situations where you're missing vendor information. I uploaded the emails and the check image I had from the photographer, and they were able to help me properly document the situation. They even provided guidance on how to file the 1099 with missing information and drafted the explanation letter to the IRS showing I made reasonable attempts to get the information. The best part was they showed me exactly what documentation I needed to keep in case of an audit. Saved me so much stress after I thought I was completely stuck!

I was totally skeptical about taxr.ai when I first read about it here, but I was desperate with my own missing W-9 situation from a website designer who disappeared halfway through last year. I decided to give it a try since nothing else was working. I'm honestly surprised how helpful it was. They didn't find my missing vendor (which I expected was impossible), but they gave me a clear process for filing the 1099 with the limited information I had. They helped me create a proper paper trail showing I made multiple attempts to contact the vendor. The step-by-step documentation guidance was exactly what I needed. My CPA was impressed with how thoroughly I had documented everything. Just wanted to come back and say it actually worked for my situation.

Have you tried calling the IRS directly about this? I had a similar issue last year and wanted clear guidance from the source. The problem is I spent HOURS on hold trying to get through to anyone who could help me. I eventually found this service called Claimyr (https://claimyr.com) that got me connected to an actual IRS agent in about 20 minutes instead of waiting for hours. They have a demo video showing how it works: https://youtu.be/_kiP6q8DX5c The IRS agent I spoke with explained that I needed to send a certified letter to the vendor's last known address (even just their email) as final documentation of my attempt to get their information before filing an incomplete 1099. Having that direct guidance from the IRS gave me peace of mind that I was handling things correctly.

Ok, I need to eat my words about that Claimyr service. After my skeptical comment, I decided to try it because I've been trying to reach the IRS about a missing tax refund for WEEKS. It actually worked exactly like they said. I got a call back when an agent was about to be available (took about 45 minutes in my case), and then I was connected directly to an IRS representative who helped solve my issue. For the original poster's W-9 problem, the agent I spoke with confirmed what others here have said - document all your attempts to get the information from the vendor (including their refusal unless you pay extra), then file the 1099-NEC with whatever information you have. They specifically said to include a statement explaining the situation and attach it to your filing. The agent emphasized that the IRS is more concerned with your good faith effort to comply than punishing honest mistakes.

One option nobody's mentioned yet is checking if the vendor deposited your check. If they did, you might be able to get their banking information from your bank statement. Sometimes you can see the account number or at least the bank they use. With that info, you might be able to find more details about their business. Worth a shot if you're completely stuck.

Have you tried being more direct with them? Sometimes I've had success by simply explaining that their request is illegal. You could send them something like: "I'm legally required to file a 1099 for the services you provided. Refusing to provide a W-9 is actually a violation of tax law and could subject you to penalties from the IRS. I'm not asking you to pay additional taxes - you're always responsible for your own tax obligations on income earned.
