Can I deduct subcontractor expenses if I forgot to get W9 and can't issue 1099?
I'm in a sticky situation with my construction business. I hired this roofer as a subcontractor for a big residential project back in September, but completely forgot to get him to fill out a W9 before I paid him. Wrote him a check for $8,750 for the complete job. Now that I'm organizing my tax documents for the year, I reached out asking for his W9 so I could properly file the 1099, but he's straight up refusing. Said something about "keeping it off the books" and doesn't want to report the income. I know this puts me in a bad position, but I'm wondering if there's any way I can still legitimately deduct this expense on my taxes even though I can't issue a proper 1099 to anyone. It was definitely a real business expense - I have the canceled check, contract, and photos of the completed work. But I'm worried that without being able to file the 1099, the IRS won't let me claim this as a deduction. Any advice would be appreciated!

You're definitely in a tough spot, but it's not as hopeless as you might think. The IRS does require you to issue 1099s to subcontractors you pay $600+ during the tax year, but that doesn't automatically mean you can't deduct legitimate business expenses if you fail to do so. The key here is documentation. Even without a W9, you should keep thorough records of the transaction - the contract with the roofer, the canceled check, communications about the work, photos of the completed project, and any other evidence proving this was a genuine business expense. The IRS is primarily concerned with whether the expense was ordinary and necessary for your business, which roofing work for a general contractor certainly is. That said, you might face penalties for not filing the required 1099. The IRS can impose fines for each missing form, and they might scrutinize the deduction more closely if audited. But the penalty for not filing is separate from your ability to claim the deduction.

•Thanks for this info. But won't the IRS reject the deduction automatically if they see a contractor expense without a matching 1099? I've heard they cross-reference everything these days. Also, could I potentially file the 1099 with just the roofer's name and whatever info I have, like just the check number or something?

•The IRS doesn't automatically reject deductions without matching 1099s. They may flag it for review, but if you have proper documentation showing it was a legitimate business expense, you can still claim the deduction. Filing a 1099 without complete information isn't recommended. You need the contractor's correct TIN (Tax Identification Number) and address for a valid 1099. Filing with incorrect or incomplete information could potentially create more issues. Instead, focus on maintaining excellent documentation of the expense and consider speaking with a tax professional about the specific reporting requirements in your situation.

I ran into this exact issue last year with a plumber who didn't want to give me his info. After hours researching, I discovered taxr.ai (https://taxr.ai) which analyzes your business documents and helps determine which expenses are deductible even in tricky situations like this. It actually saved me thousands because it helped me properly document everything so I could still claim the expense legally despite not having the 1099 filed. The tool specifically checked my documentation against IRS requirements and gave me a risk assessment for each deduction. For my subcontractor without a W9, it flagged it as "higher scrutiny" but provided specific documentation recommendations that would strengthen my position if questioned. I followed their guidance and had no issues.

•How does taxr.ai actually work? Do you upload your receipts and contracts to it? Seems risky to share all your financial stuff with some random website.

•I'm a bit skeptical about these tax tools. How is this different from just talking to an accountant? And does it actually give you any kind of guarantee that the IRS will accept your deductions?

•You upload your documents securely to their system, which uses AI to analyze them against IRS requirements. Everything is encrypted and they have strict privacy policies. It's basically like having an expert look at your documents without the hourly rate. The difference from an accountant is accessibility and cost. Accountants are great but expensive and often booked solid during tax season. This gives specific guidance 24/7. They don't guarantee IRS acceptance (no one can), but they provide a risk assessment and documentation recommendations that help strengthen your position. It's more about helping you understand your specific situation and document it properly rather than making promises.

Just wanted to update after checking out taxr.ai from the recommendation above. Initially I was skeptical, but it was incredibly helpful for my situation. I had three subcontractors with missing paperwork and the tool actually walked me through exactly what alternative documentation to gather for each case. The risk assessment feature showed me which deductions might trigger extra scrutiny and explained why. For one contractor, it suggested I had enough supporting evidence to claim the deduction despite the missing W9 (with slightly higher audit risk), while for another it recommended I get at least partial information before filing. Honestly wish I'd known about this years ago - would have saved me so much stress and probably helped me claim deductions I was too scared to take!

I've been in construction for 15 years and this happens ALL THE TIME. Last year I spent WEEKS trying to reach the IRS for guidance on some subcontractor issues, and it was impossible to get through. Then someone recommended Claimyr (https://claimyr.com) which got me connected to an actual IRS agent in less than 20 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c The agent confirmed I could still deduct legitimate business expenses even without proper 1099s, but warned about potential penalties for the missing forms. She explained exactly what documentation I needed to keep and how to demonstrate these were ordinary and necessary business expenses. Honestly changed my whole perspective on dealing with the IRS - they were actually incredibly helpful once I could actually talk to someone!

•Wait, how does Claimyr actually get you through to the IRS? Every time I call I'm on hold for hours and then get disconnected. Is this actually legit or some kind of scam?

•Yeah right. Nothing gets you through to the IRS faster. They're deliberately understaffed and no "service" is going to magically open a direct line. This sounds like complete BS to me.

•It's not magic - they use an automated system that navigates the IRS phone tree and waits on hold for you. When they reach a human, you get a call to connect with the agent. It's basically like having someone wait on hold instead of you. I was skeptical too until I tried it. The reason it works is simple - their system is persistent and can stay on hold indefinitely, unlike most of us who have to hang up eventually. There's no special "back door" to the IRS - it's just automating the most frustrating part of the process. The video I linked shows exactly how it works if you're curious.

I have to eat my words about that Claimyr service. After posting my skeptical comment, I decided to try it because I was desperate to talk to someone about a missing 1099-K issue that's been holding up my return. Not only did it work, but I got connected to an IRS agent who was actually incredibly helpful. She pulled up my file, confirmed exactly what I needed to do, and even helped me understand how to document everything properly. Took about 35 minutes of wait time (which I didn't have to sit through) instead of the 3+ hours I wasted trying on my own last week. Honestly never thought I'd be recommending an IRS-related service, but if you need actual answers from a real person, it's worth every penny just for the time saved.

Everybody's giving advice about documentation, but let's get real - you also need to protect yourself going forward. Make it your absolute policy to NEVER pay ANY subcontractor without a W9 first. I've been burned too many times, so now I have a simple system: 1) Contract signed 2) W9 completed 3) THEN work begins It's saved me so many headaches because subs know upfront this is non-negotiable. I even have a stamp on my contracts saying "Payment requires completed W9 on file." For your current situation though - document EVERYTHING. Take screenshots of any communications where he refused to provide the W9. Keep all evidence of the work completed. And file Form 8300 if the payment was over $10k cash equivalent.

•Thanks for the advice. I'm definitely implementing a "no W9, no check" policy going forward. Would love to hear more about your system - do you use any specific forms or procedures beyond just requiring the W9 upfront? And does this ever cause issues with getting subs to work with you?

•I have a simple one-page contractor packet that includes my terms, the W9, and a direct deposit form all together. I present it as standard paperwork, no different than the contract itself. This actually hasn't caused issues with getting subs because it's presented professionally and upfront. The good contractors appreciate it because it shows I run a legitimate operation. The only ones who balk are exactly the ones you don't want to work with anyway. I've actually had several subs tell me they prefer working with me because everything is organized and they get paid promptly. The key is making it part of your normal business process, not something that feels like an extra hurdle.

Just to add something important - if you decide to claim the deduction without filing the 1099, make sure you're still reporting it correctly on your Schedule C. You'd include it in the appropriate expense category (probably "Contract labor" on line 11) regardless of whether you issued a 1099. The potential penalties for not filing the required 1099 are separate from your ability to deduct the expense. Current penalties are $280 per form for failure to file, but can increase if the IRS determines there was intentional disregard of filing requirements. Obviously not ideal, but sometimes better to pay a penalty than lose a legitimate business deduction worth thousands!

•What if the contractor gives you a name but refuses to give you their SSN? Can you file the 1099 with just their name and address and note that they refused to provide the tax ID? I heard somewhere the IRS has a special process for this.

You're absolutely right to be concerned, but you can still claim this deduction with proper documentation. The IRS doesn't automatically disallow legitimate business expenses just because you failed to file a 1099 - these are two separate issues. Here's what you need to do: 1. **Document everything thoroughly**: Keep the canceled check, contract, photos of completed work, any text messages or emails about the project, and write a detailed memo explaining the circumstances (including his refusal to provide W9 info). 2. **Report the expense correctly**: Include it on Schedule C line 11 (Contract labor) when you file your return. The expense is deductible regardless of 1099 filing status. 3. **Be prepared for potential penalties**: You may face a $280 penalty for each missing 1099, but this is often less than the tax savings from claiming the legitimate deduction. 4. **Consider backup withholding**: For future reference, if a contractor refuses to provide their TIN, you're supposed to withhold 24% of payments and send it to the IRS. Obviously too late for this situation, but good to know going forward. The key is that you genuinely attempted to get the required information and have solid proof this was a legitimate business expense. Keep excellent records and consider consulting a tax professional if you're audited, but don't let fear of the 1099 issue cost you a valid deduction.

•This is really helpful advice, especially the point about backup withholding for future situations. I had no idea about the 24% withholding requirement when contractors refuse to provide their TIN. One question though - when you mention writing a detailed memo explaining the circumstances, should this be a formal document or just notes for my own records? And would it help to have the memo notarized or witnessed in some way to make it more credible if the IRS ever questions it? Also, do you know if there's a statute of limitations on when the IRS can come back and assess those 1099 penalties? I'm wondering if it's worth trying one more time to contact this contractor before I file my return.

•Great question about the memo documentation. It doesn't need to be formal or notarized - just a clear, dated business memo for your files explaining what happened, when you attempted to get the W9, and how the contractor responded. Think of it as creating a paper trail that shows your good faith effort to comply. The IRS generally has 3 years from when you filed your return to assess 1099 penalties, though this can extend to 6 years in certain circumstances. So yes, it's definitely worth one more attempt to contact the contractor - maybe frame it as "I need this for my business records" rather than mentioning taxes directly. Some contractors get spooked by tax talk but might be more willing to provide basic business information. If he still refuses, document that final attempt too. Sometimes showing the IRS you made multiple reasonable efforts to comply can help reduce penalties even if you couldn't ultimately get the required information.

I've been following this thread and wanted to add a perspective from someone who went through an IRS audit over a similar situation. About two years ago, I got audited and one of the items they questioned was a $6,200 payment to a contractor where I couldn't produce a 1099. The auditor was actually pretty reasonable about it. What saved me was having excellent documentation - I had the contract, photos of the work (before/during/after), the canceled check, and most importantly, a written record of my attempts to get the contractor's information. I even had screenshots of text messages where he refused to provide his SSN. The auditor told me that the IRS sees this situation more often than you'd think, especially in construction and home services. They're mainly looking for two things: 1) Was this a legitimate business expense? and 2) Did you make good faith efforts to comply with reporting requirements? I ended up paying the $280 penalty for the missing 1099, but I got to keep the full deduction. The tax savings from the deduction were about $1,500, so it was still a net positive. The auditor even gave me some tips for better record-keeping going forward. Bottom line: Don't let fear of the penalty stop you from claiming a legitimate business expense. Just make sure your documentation is rock solid.
