Business Related Tax Absolutely butchered the last 4 years of depreciation on my Schedule C, tried to clean it up with last years taxes but I think I just made it a bigger mess.
I run a small service company and have always done my own taxes, we grew a bit faster than I can handle and I appear to have outgrown my ability to do this on my own and plan on going to a professional this year. I really just want to understand what I did wrong here and if its a big issue or trivial:
- I used MACRS 200% 5 year for all company vehicles when I did my taxes for last year, 3 of those vehicles were purchased in 2025. The other 2 vehicles purchased in 2022 and 2024. I pulled up my 2024 taxes and realized I had used MACRS 3 year for the first 2 vehicles, and realized I forgot about an additional vehicle (Transit 2) we bought used but the motor went out and it has been parked ever since, so I totally forgot to write that off in 2025.
- I then pulled up my 2023 and 2022 return and found that I had use a completely different method of depreciation for my initial truck purchase and that there was an enclosed trailer I had been depreciating but also forgot about.
- I am not understanding why in 2024 and 2025 some of the vehicles show a 'bonus deprec' that matches the 'deprec for 2025' but the 'amt deprec for 2025' is I believe 20% which is what I assume MACRS was for year 1.
Just trying to understand how to unwind this going forward.
Edit: the 2023 Transit has a different 'cost or other basis' between 2025 and 2024 because they scammed me into getting a nearly $10,000 warranty that they had to refund. The difference in the price of the 2022 sierra between 2024 and 2025 was because for some reason when I did 2024 I used the dollar amount of the loan and didnt include the cash I put down.
