In order to enter these expenses, you will compute the total of the purchase price of supplies for the drywall, insulation, and the $450 labor for the drywall. Your personal labor is not deductible.
Here is how to enter the costs:
1. Navigate to Federal > Wages & Income > Rentals, Royalties, and Farm > Rental Properties and Royalties (Sch E)
2. Select the Rental property by clicking the pencil
3. Choose Add expense of asset
4. Decide if this is an asset or repair. If you classify it as an asset, you can choose to deduct the amount under Section 179, if qualified. You may also be able to substantiate the expense as a repair. The room you remodeled cannot be a major component of the condo; the work cannot have been a betterment, restoration, or adaption of the unit of property. For a definition of those tests, see Tangible property regulations – Frequently asked questions.
