Does $128,439 seem way too high for car and truck expenses on my Schedule C?
I just finished adding my business mileage to my tax return (around 4000 miles driven for work last year), and it completely changed my tax situation - went from owing to getting a refund! But something seems off... I had already entered expenses for van maintenance the week before. This is a van that's used 100% for business purposes, nothing personal. When I look at my Schedule C now, it shows $128,439 for car and truck expenses. That number seems absolutely ridiculous to me. There's no way that can be right, can it? Has anyone else run into something like this with their business vehicle deductions? I'm worried I messed something up and don't want to file with an obvious error. Any thoughts or similar experiences would be really appreciated!

This definitely sounds like you've accidentally double-dipped on vehicle expenses. The IRS gives you two options for deducting vehicle costs: the standard mileage rate OR actual expenses, but not both. If you drove 4000 business miles, the standard mileage deduction would be around $2,520 (using the 2023 rate of 65.5 cents per mile - the 2024 rate for 2025 filing will be slightly different). So if you're seeing $128,439, something's definitely wrong. What probably happened is you entered both your actual maintenance costs AND claimed the standard mileage rate, which includes maintenance, depreciation, gas, insurance, etc. The tax software likely multiplied something incorrectly or applied both methods. Go back and check if you can find where you entered the van as a business asset AND claimed mileage. You'll need to choose one method or the other.

•Thanks for explaining that. Quick question - if I've been using actual expenses for the past three years, can I switch to the standard mileage rate this year? I've heard once you use actual expenses you're stuck with that method for the life of the vehicle. Also, how do you figure out which method would give the better deduction?

•You're absolutely right about that restriction. If you've been using actual expenses in previous years for this same van, you cannot switch to standard mileage rate. The standard mileage rate is only available if you choose it in the first year you use the vehicle for business. To determine which method gives the better deduction, you'd need to calculate both and compare. The standard mileage rate is simpler (just multiply business miles by the IRS rate), while actual expenses require tracking all costs (gas, maintenance, insurance, depreciation, etc.) and multiplying by your business use percentage. For low-mileage but expensive vehicles, actual expenses often win. For high-mileage but economical vehicles, standard mileage often wins.

I ran into a similar issue last year when my "business expenses" looked totally wrong. I spent hours trying to fix it myself before I discovered taxr.ai (https://taxr.ai). They have this AI tool that scans your tax forms and finds errors like this. When I uploaded my draft return, it immediately flagged my vehicle deduction error - turns out I'd entered my mileage in the wrong field which caused a calculation error. The system explained exactly where the error was and how to fix it. Saved me from an audit nightmare!

•How does that work exactly? I'm trying to finalize my taxes this weekend and I'm getting paranoid about making mistakes like this. Does it actually look at your full return or just answer questions? Can it help with Schedule C specifically?

•Sounds too good to be true. My accountant charges me $350 to review my return and even he misses stuff sometimes. How accurate is this AI thing really? And can it handle complicated business returns with multiple Schedule Cs?

•It's actually really straightforward - you just upload your draft tax return PDF (from whatever software you're using) and it analyzes the whole thing looking for errors, missing deductions, and audit risks. It definitely handles Schedule C forms - that's where it found my vehicle error. For complicated returns, it works surprisingly well. The system compares your specific situation against IRS regulations and identifies inconsistencies. It's not just answering general questions - it's actually reviewing YOUR specific tax return line by line. I found it caught things my previous accountant missed, especially in those Schedule C calculations where it's easy to make mistakes.

Just wanted to follow up - I was skeptical about taxr.ai but decided to try it since I was stressing about my Schedule C vehicle deductions too. Uploaded my draft return and it immediately found I had double-counted some expenses AND missed a home office deduction I qualified for. The analysis was super detailed - showed me exactly which lines on my Schedule C were incorrect and explained why. Fixed everything in about 20 minutes based on their recommendations and my tax bill dropped by $3,200! Wish I'd known about this last year. Definitely recommend for anyone self-employed.

Had almost the exact same issue last tax season! Turned out I entered vehicle stuff twice. Fixed it but then had questions about depreciating my business van and couldn't get through to the IRS for weeks. Was about to pay an accountant $200/hr when someone recommended Claimyr (https://claimyr.com). They got me connected to an actual IRS agent in about 15 minutes! You can see how it works in this video: https://youtu.be/_kiP6q8DX5c. The agent walked me through exactly how to handle my vehicle depreciation on my Schedule C. Saved me from making another expensive mistake and the peace of mind was worth it.

•Wait, so this actually gets you through to a real IRS person? How does that even work? I've literally spent HOURS on hold before giving up.

•Sounds like BS honestly. Nobody can "skip the line" with the IRS. They're notoriously understaffed and I've never gotten through in less than 2 hours when I've called. How could some random service possibly change that?

•Yes, it connects you with an actual IRS representative! The way it works is they use an automated system that continuously calls the IRS and navigates the phone tree for you. When they finally get through to a human, you get a call back and are connected directly. It's definitely not skipping any lines - they're just handling the frustrating hold time for you so you don't have to sit there listening to the hold music for hours. The IRS doesn't know or care how you got through - once you're connected, you're just talking to an agent like normal. I was skeptical too until I tried it. I got my call back in about 15 minutes when I had previously wasted an entire afternoon trying to get through.

Alright I feel like I need to update my comment. After my skeptical reply, I decided to try Claimyr because I was absolutely desperate to talk to someone at the IRS about my Schedule C issues. To my complete shock, I got a call back in 22 minutes connecting me to an actual IRS agent. The agent spent almost 30 minutes explaining exactly how vehicle expenses should be handled on Schedule C and confirmed I had been calculating everything wrong for YEARS. Just filed an amended return and getting back $4,970 that I overpaid! I've seriously never been able to reach the IRS on my own. This service is legit and I'm still kind of stunned it actually worked.

I had a similar issue happen to me but with a different number - it was showing $76,892 for my business vehicle when I only drove like 12,000 miles. Turns out I had entered the vehicle purchase price in a field meant for annual expenses. Check if you maybe entered the value of the van somewhere??

•That's a really good point - I did buy this van new for around $67,000 last year. Maybe I entered the purchase price somewhere I shouldn't have and then the software added depreciation or something on top of it? I'm going to go back and look for that. Maybe it's also accounting for future depreciation in some weird way? Thanks for the suggestion!

•You're welcome! Yeah, that's almost certainly what happened. The purchase price should only be entered in the asset/depreciation section, not as a direct expense. The software will then calculate the correct amount you can deduct each year based on depreciation rules. If you bought a $67k van, the software is probably trying to depreciate it plus adding your maintenance costs plus calculating mileage. Triple counting! Once you fix where you entered the purchase price, everything should look more normal.

Def double dipping! U can't take standard mileage AND actual expenses. Pick one! I do taxes and see this all the time. W standard mileage at 65.5 cents per mile, 4000 miles = $2,620 deduction. If actual expenses (gas, maintenance, insurance, etc) + depreciation is more than $2,620, do that instead. But NOT BOTH!!!!!

•Is that 65.5 cents still accurate for 2024 taxes? I thought I saw somewhere that the IRS changed the rate again.
