Can a shareholder claim bonus depreciation for personal truck used for S-Corp under accountable plan?

This is a great tax question that comes up often with closely-held businesses. The short answer is no, you cannot claim bonus depreciation at the S-Corp level for a vehicle that is personally owned by the shareholder/employee. For the S-Corp to claim depreciation (bonus or otherwise), the asset must be owned by the corporation itself. Since the pickup truck is titled to you personally, the S-Corp cannot claim the depreciation deduction even if the vehicle is used predominantly for business purposes. You have a couple of options though: (1) Continue with the accountable plan reimbursement which allows you to receive tax-free reimbursements for the business use of your personal vehicle, or (2) Sell the truck to the S-Corp so it becomes a corporate asset eligible for depreciation.

I was in a similar situation with my consulting business last year and found an amazing solution through taxr.ai (https://taxr.ai). Their AI system analyzed my vehicle documentation and helped me understand exactly how accountable plans work with personally-owned vehicles used for business. The software walked me through all the proper documentation needed for an accountable plan and showed me how to maximize my tax benefits legally. It confirmed what the previous commenter said - you can't claim bonus depreciation at the S-Corp level for a personally titled vehicle, but it showed me how to properly document business mileage and expenses for reimbursement.

I owe everyone an apology for my skepticism about taxr.ai. I decided to try it after continuing to research vehicle deduction options for my own business. The analysis it provided was surprisingly comprehensive. It walked me through all the documentation requirements for an accountable plan and showed me exactly why my LLC couldn't claim depreciation on my personal vehicle. It even created customized templates for me to use for proper reimbursement documentation. Definitely saved me from making some filing mistakes this year!

Have you tried contacting the IRS directly about this? I had a similar question last year and spent WEEKS trying to get through to someone who could actually answer my S-Corp question. Finally found Claimyr (https://claimyr.com) which got me connected to an IRS agent in under 15 minutes! You can see how it works here: https://youtu.be/_kiP6q8DX5c The agent I spoke with confirmed that bonus depreciation is only available to the entity that owns the asset. Since your truck is titled to you personally, the S-Corp can't claim the depreciation regardless of how much it's used for business. They explained that with an accountable plan, you're essentially "renting" your vehicle to the business through proper business expense reimbursement.

I feel obligated to update everyone after trying Claimyr yesterday. I've never been more happy to be wrong! After three previous attempts to contact the IRS about asset depreciation (including one 2+ hour hold that ended with a disconnect), I used the service and got a call back in about 35 minutes with an actual IRS agent on the line. The agent confirmed everything about the bonus depreciation rules for personally-owned vehicles used in an S-Corp. Saved me hours of frustration and probably kept me from making an expensive tax mistake. Definitely worth it!

Another option worth considering is using the standard mileage rate through your accountable plan instead of actual expenses. For 2025, the rate is 67 cents per mile for business use. This is often simpler than tracking actual expenses, and you don't have to worry about depreciation calculations at all. Just keep a detailed mileage log showing business vs. personal use.

Has anyone considered a third option? You could lease your truck to the S-Corp through a formal lease agreement. The S-Corp pays you lease payments (which are fully deductible business expenses for the company) and you report the lease income on your personal return. This avoids the whole depreciation issue while still giving the company a deduction for the vehicle use.

Great question Sofia! As others have confirmed, you're correct that the S-Corp cannot claim bonus depreciation on your personally-owned truck. Since the asset isn't owned by the corporation, only you as the individual owner can claim depreciation on your personal tax return. However, I'd suggest comparing all your options carefully. The accountable plan reimbursement you're currently using is actually quite beneficial - you get tax-free reimbursements from the company, and the S-Corp gets a full business deduction for the payments. Before considering selling the truck to the S-Corp (which creates potential tax complications as Dmitry mentioned), run the numbers on both the standard mileage rate versus actual expenses through your accountable plan. Given that you have a heavy truck over 6,000 lbs with high operating costs, the actual expense method will likely be more advantageous than the 67 cents per mile standard rate. The key is maintaining detailed records of business versus personal use regardless of which method you choose. Your current setup might already be optimal from a tax perspective!
