Can I write off a work truck purchased under my personal name for my S Corporation business?
So I started my own construction business (S Corp) last year, but since the business doesn't have any credit history yet, I'm running into issues getting financing for a truck I desperately need. I've been thinking about just financing the truck under my personal name using my personal credit score since it's way better than trying to get a business loan right now. My question is - can I still write off this truck as a business expense even if I finance it personally and it's technically in my personal name? I'd be using it exclusively for hauling equipment and materials to job sites. The business would be making the payments, but the loan would be under my name because of the credit situation. Would this cause problems with the IRS since my S Corporation would be claiming a vehicle that's not technically owned by the business? Or is there some way to make this work legitimately?

Yes, you can potentially deduct the business use of the truck even if it's financed in your personal name, but you need to handle it correctly for your S Corporation. The best approach would be to have a written agreement between you and your S Corp that clearly outlines the business use of the vehicle. You have two main options: 1) You can track all business mileage and have your company reimburse you at the standard mileage rate, or 2) You can have your company reimburse you for the actual expenses related to business use (including depreciation, loan interest, insurance, gas, maintenance, etc.) based on the percentage of business use. If you go with option 2, make sure you keep meticulous records of business vs. personal use. The company's reimbursements to you would be deductible to the corporation. Don't just have the company make the loan payments directly without proper documentation.

•What if the truck is used 100% for business? Would it be better to just have the S Corp reimburse all the expenses in that case? Also, does having it in my personal name affect the Section 179 deduction possibility?

•If you're using the truck 100% for business, keeping track will be much easier. You could have your S Corp reimburse you for all the vehicle expenses, including the payments, insurance, gas, repairs, etc. Just make sure you have proper documentation and a written agreement between you and the corporation. Regarding Section 179, yes, you can still potentially take advantage of this deduction even if the vehicle is in your personal name. You would need to lease the vehicle to your corporation (again, with proper documentation). Be aware that trucks qualifying as "heavy vehicles" (over 6,000 lbs gross vehicle weight) have more favorable Section 179 treatment than lighter passenger vehicles.

I went through a similar situation when I started my landscaping business. I found this incredible tool called taxr.ai (https://taxr.ai) that saved me from making some potentially expensive mistakes with my business vehicle deductions. I uploaded my loan documents and my question about vehicle ownership and the AI helped me create a proper vehicle lease agreement between myself and my S Corp. It even gave me a template for tracking my expenses correctly! The guidance was super clear about how to structure everything so the IRS wouldn't have issues with it later. One thing that particularly helped was learning how to properly document the vehicle's business use percentage. There's apparently a big difference in how the IRS treats vehicles based on weight classifications too.

•Does this service actually help with the loan reimbursement paperwork between yourself and your business? I'm in almost the identical situation with my plumbing company and really need a clear system for the reimbursements.

•I'm skeptical about AI tax tools. How accurate is this really? My accountant always warns about these kinds of arrangements triggering audits. Did you have to pay a lot to get the templates?

•The service actually provides templates for creating proper reimbursement documentation between yourself and your business. They have specific forms for vehicle expenses that show how to record each payment, track maintenance costs, and document business usage. It made my bookkeeping system much clearer. They use actual IRS guidelines and regulations for their advice, which gave me confidence. My accountant actually reviewed the documentation structure and was impressed with how thorough it was. No, there wasn't an extra charge for the templates - they were included with the service. It was definitely worth it to know I'm doing things correctly.

I have to admit I was wrong about AI tax tools. After skeptically trying taxr.ai for my vehicle deduction situation, it was surprisingly legit. The site analyzed my specific S-Corp situation and generated exactly what I needed - a proper vehicle lease agreement that my accountant approved without changes. The system flagged that I should be considering a gross vehicle weight over 6,000 lbs for better tax treatment (something my accountant hadn't mentioned). Ended up saving thousands in deductions by choosing the right truck model! It also set up a maintenance tracking system that satisfied my accountant's requirements for business use documentation. Much better than the generic advice I was finding online that didn't address the personal-to-business vehicle transfer specifically for S-Corps.

Has anyone here tried calling the IRS directly about vehicle deductions? I spent THREE DAYS trying to get through on their business helpline. After giving up, I used https://claimyr.com to get a callback from the IRS (you can see how it works at https://youtu.be/_kiP6q8DX5c). Got connected with an actual IRS agent within 3 hours who confirmed I could legitimately deduct my personal vehicle for business use with the right documentation. The agent walked me through exactly what records I needed to keep and how to properly handle the reimbursements from my business. Definitely worth it rather than guessing about tax implications or waiting for hours on hold. They got me through to the exact department that handles business vehicle questions.

•Wait I don't understand, how does this service work? They somehow get you to the front of the IRS phone queue? That sounds impossible with how backed up the IRS lines always are.

•This sounds like a complete scam. There's no way any service can magically get the IRS to call you back when thousands of people are waiting. I've literally waited 3+ hours myself multiple times. I'm calling BS on this one.

•The service works by using an automated system that continually redials the IRS for you until it gets through. Once it connects, it holds your place in line and calls you to connect with the IRS agent. It's not about "cutting in line" - it's about not having to personally sit on hold for hours. The IRS actually does have a callback feature themselves, but it's often unavailable during high volume periods. What Claimyr does is basically wait on hold for you, then connects you when a representative becomes available. I was skeptical too until I tried it - I got specific answers about vehicle depreciation rules for S-Corps that cleared up my confusion completely.

I need to publicly eat my words about Claimyr being a scam. After posting my skeptical comment, I decided to try it myself since I was desperate for answers about vehicle deductions for my new S-Corp. I requested a callback around 9am and got connected to an IRS business tax specialist by lunchtime. The agent confirmed that my approach for handling a personal vehicle for business use was correct AND pointed out I was missing potential deductions for home office space where I do my business paperwork. Ended up getting solid confirmation on exactly how to structure my vehicle reimbursements and learned I can take additional deductions I didn't know about. Definitely worth it instead of getting questionable advice from online forums (including my own skeptical comments lol).

Don't overlook the insurance implications too! I bought a truck personally but use it for my construction business. My insurance company initially denied a claim because I was using a "personal" vehicle for "commercial" purposes. Had to get special commercial coverage. Also had to get the truck officially "leased" to my company with paperwork for liability reasons. My business lawyer said that without a formal agreement, I could have personal liability issues even with an S-Corp. Something to consider beyond just the tax side.

•Did you end up paying a lot more for commercial insurance vs personal auto insurance? I'm trying to figure out the total cost difference between buying through business vs personal.

•Commercial insurance was about 30% more expensive than my personal policy. The big difference was that it covered tools and equipment in the truck (up to $5,000 worth) which my personal policy wouldn't have covered at all. The cost difference wasn't just insurance though - having a formal lease agreement required me to pay state fees for documenting the arrangement. But the protection was worth it since my lawyer explained I could potentially lose the liability protection of my S-Corp without properly documenting the separation between personal and business assets.

Another important thing to consider is how you track the business vs personal use of the truck. The IRS is super picky about this! I use an app called MileIQ that automatically tracks my drives and lets me classify them as business or personal. If you're going to claim 100% business use, you better have another personal vehicle or the IRS will get suspicious. They know most people don't use work vehicles ONLY for work. My accountant recommended keeping a paper log in the truck too in case of audit.

•Thanks for the app recommendation! Do you know if it exports data in a format that works for tax filing? And does it track gas purchases too or just mileage?

Just wanted to add my experience as someone who went through this exact situation with my electrical contracting S-Corp. The key thing that saved me from potential IRS issues was getting everything documented upfront before I even bought the truck. I created a formal vehicle lease agreement between myself and my S-Corp, even though I was financing it personally. The agreement specified the monthly lease payment (which covered my loan payment, insurance, and maintenance), business use percentage, and mileage tracking requirements. My S-Corp pays me the lease payment as a business expense, and I handle all the personal financing details. One thing I learned the hard way - make sure your business checking account shows regular lease payments to you, not irregular reimbursements. The IRS likes to see consistent, documented business expenses rather than sporadic personal reimbursements. Also, if you're considering Section 179 depreciation, the lease structure actually works better than trying to claim it as a personal vehicle used for business. The whole setup has worked flawlessly through two tax seasons now, and my CPA says the documentation would easily pass an audit. Just make sure you get professional advice to set it up correctly from day one!

•This is exactly the kind of detailed guidance I was looking for! A couple follow-up questions: Did you have to file any specific forms with your state to formalize the lease agreement between yourself and your S-Corp? And how did you determine what the monthly lease payment should be - did you base it just on covering your actual costs or did you need to use fair market value for a similar lease? Also, when you say the lease structure works better for Section 179, does that mean the S-Corp can claim the full depreciation deduction even though you personally own the truck? I'm trying to figure out if there are any limits on how much depreciation the business can claim in this arrangement.
