Repairs vs. Improvements
You can deduct the cost of repairs on your rental property in the year you paid. However, you may not deduct the cost of improvements. You must recover the improvement cost through depreciation, rather than deducted in the year paid.
A repair just keeps the property in good operating condition and does not materially add value to the property. Some examples of repairs are: painting, fixing leaks and cracks, repairing broken gutters, and replacing broken doors or windows or other parts of the rental property.
