We lived in the SFH and replaced all of the original windows and sliding doors in October 2019 to improve energy efficiency. (They were 40+ yo) We moved out and converted the SFH into a rental in March 2021.
On our expenses, can we now claim depreciation of the cost of windows and doors?
I don’t see how. But, maybe? Your cpa should be able to tell you your cost basis. (Since it was already a rental last year I assume they’ve already done all the math.) I THINK you have to use the costs from when you actually bought it, not the stepped up value of when it because a rental. Which is why you want to make sure you aren’t converting a bunch of tax free appreciation into taxable gains.
I believe all major improvements add to your cost basis for depreciation purposes. The cost basis is purchase + capital improvements whether you owner occupied it or not (same formula goes for capital gains). What if it was a rehab house? Most certainly rehab costs would go into it.
Regular maintenance doesn’t count. Double check with your tax accountant as I am not one.
Sounds like you made the improvement before you put the property into service as a rental. So, the costs would be applied to your cost basis for your home -- just like any other situation. Because its in your cost basis, you are effectively depreciating, some of it anyway, via your current depreciation schedule.
If you had made a significant capital improvement AFTER you put the property into service, then you would depreciate that improvement directly.
Yes, you can depreciate it, with all the details already mentioned on this thread.
Just to make sure we're on the same page, the depreciation will be slow: it's spread evenly over 27.5 years. If you were thinking of the 100% bonus depreciation, it does not apply to windows and doors, regardless of the history of this property.
