I am having the same problem with determining the prior depreciation equivalent and AMT depreciation equivalent. I sold an older model vehicle (2011) in August of 2022 to a junk car place as it blew an engine gasket. The car's cost basis was $21,000 when originally purchased and sold for $450. I used a professional tax service for 2020 and 2021. The first year (2020) the calculation method was S/L-HY and depreciation deduction/"special allowance deduction" was $6,488 and the next year (2021) the calculation method was DB200HY for for a "current allowance deduction" of $4,904. Would I use DB200HY to calculate the current 2022 tax year's depreciation deduction? I add these three numbers up for the depreciation equivalent number? How would that apply to the AMT depreciation equivalent?
