Investors & landlords

Yes, the windows will be input in assets. As my colleagues stated, assets begin depreciating in the year of purchase for the full cost.  The payment of a loan has no impact on income, except the interest paid.  Interest is a deductible expense.

Here are the instructions:

1. Navigate to Federal > Wages & Income > Rental Properties and Royalties (Sch E)
2. Edit the rental using the pencil icon
3. Navigate to Assets, choose pencil icon if you have an asset already set up and are adding more, or choose to Add expense or asset if not.
4.  Now, you will see Your Property Assets with depreciation already computed. Add an asset.  Then, follow the interview to answer details about the cost of the asset.
