Question to Vagabond or others; can depreciation be total price plus appliances or is "capital improvements only something "permanent"; does it matter? I thought it had to be something "attached". Also makes me wonder about HVAC....lots of searching to do.
Depreciate the total price. Depreciate the appliances, new carpet, or other fixtures separately only if you buy them separate from the house.
So if you buy a fixer upper and add a bunch of stuff can that can be depreciated? Does it have to be?
As is usually the answer with taxes: "it depends."
In general, if you buy a property to be fixed up for rental, costs incurred to get the building rentable before it is placed in service (i.e. available to be rented) are capitalized. My favorite example: if you paint a wall as part of a larger, capitalized improvement, it must be depreciated. If you paint a wall and don't do anything else, it can be expensed. So you can perform the same action, but depending on the other circumstances it can be treated differently. Once it is placed in service, the rules get more nuanced.
If you are buying larger properties, investigate having a cost segregation done. New rules state partial write-offs are allowed if you can establish what the original amount allocated to it should be. I.e., if you can allocate part of the purchase price to kitchen cabinets as part of the purchase, when you replace those, you can write off the old ones. Otherwise it's all lumped into "building." This is only really cost-effective for an apartment multiplex or large commercial. For single-family homes through small apartment buildings, the cost of the study will be greater than any benefit you'll receive (my opinion).
Depreciation is not optional - if an asset is depreciable, depreciation must be taken on it. The trickier part is deciding what is depreciable and what can be expensed.
No, depreciation and taxes are not rocket science to get them "close enough," but if you want to be correct all the time, it will take a lot of research. I've not seen "Turbo tax said to do it this way" hold up to an IRS audit, so you still need to understand the theory behind why it is being treated a certain way on your taxes. I'm not saying go out and hire a CPA, I'm saying make sure you understand why you are presenting things a certain way on your tax return.
Also be careful with the EA versus CPA designation. There are very good tax people with either, and there are shady tax people with either. The CPA test does cover more than taxes, but a good tax CPA will concentrate solely on taxes for their profession. The CPA has higher continuing education and harder licensing testing than the EA.
Again, note my bias, and take with a grain of salt.
