I am in the exact same situation. Claimed section 179 on an SUV over 6000lbs placed in service 12/2017. I have always kept it slightly above the 50% business use and would like to let it drop below. The questions are:
1. For 179 deduction considerations, is the 5 years up on 12/2022 or for tax year 2022? i.e., do I need to show business use was above 50% until December of 2022? Edit, I now see what AmeliesUncle said which is that 100% would have already been depreciated in 2022 using the straight-line method so the actual month does not matter.
2. For depreciation considerations after 5 years, can I use the vehicle for pretty much anything I want, but must just list it as a business vehicle forever (or until the value drops below the basis) to avoid a depreciation recapture?
