Yes, you will report all the assets. When entering the assets, you will report when you purchased the asset (this year or prior) and when you started using it in your rental (Aug 2017, for example).
You can take a special depreciation allowance to recover part of the cost of qualified property (defined next), placed in service during the tax year. For qualified property placed in service in 2017, you may be able to take an additional 50% or 100% special depreciation allowance, depending on the date you acquired the qualified property. The allowance is an additional deduction you can take after any section 179 deduction, and before you figure regular depreciation under MACRS for the year, you place the property in service.
All expenses must be deducted in the year they are paid.
What kinds of rental property expenses can I deduct?
