Tax Filing & Cost Segregation

[Neera Melwani]

Hi Everyone! In 2022, I was taking SL depreciation for my rental properties (1 apartment building and 4 4-plexes). I did a cost segregation study in order to take advantage of bonus depreciation and I have  a couple questions.

1. Does the form 3115 need to be filled out and approved PRIOR to making the change? 

2. Is the change ever not approved?

3. Do I need to amend prior returns, or can I take the catchup all in 2023?

4. Has anyone ever done this themself using TurboTax? I've used CPAs in the past, and prefer to do the accounting myself.

Thank you!
