How to fix incorrect rental depreciation
An in-law suite in my house has been used as an Airbnb rental since 2019.
2022 was the first year I claimed depreciation on Schedule E, but Form 4562 did not accompany my return since I entered the actual in service date as 2019. Also, the depreciation amount/calculation was slightly low due to an incorrect land value being entered. I'm seeking advice on how to best fix the missed depreciation from 2019-2021 and the incorrect land value in 2022.
Should I...
a) Just enter the correct depreciation on my 2023 Schedule E and keep the in service date as 2019, knowing that I missed claiming a few years of depreciation? My understanding is that this really only matters when I go to sell the property. The depreciation "lost" isn't considerable - the room is only 13% sq ft of a $300,000 property purchased in 2018.
b) Amend my 2022 tax return Schedule E to correct the land value amount and enter 1/1/2022 as the in service date of the property? I assume this would generate a Form 4562 and I could move forward claiming the correct depreciation amount each year moving forward.
c) File a Form 3115 to correct the years that weren't depreciated and correct the land value. I assume this would permit me to claim the missed depreciation in 2023. If so, where do I enter this additional depreciation? Which DCN reason would I use for Form 3115?
Any suggestions or other ideas are welcome!
