How do I deduct home improvements on my tax return?
Home improvements are not usually deducted on your tax return. You may deduct mortgage interest and real estate taxes as Itemized Deductions on Schedule A. Other types of home expenses are generally not deductible.
If you have a home office for your business, you can deduct some of your home expenses and home improvements. Those expenses are entered on the Home Office screen in the Business Income section. If the home is a rental property, then home expenses are entered on Schedule E to offset any rental income you are receiving.
Usually, home improvements are simply added to the cost basis of your home. For example if you bought a home for $100,000 and then build a deck for $5,000, the cost basis of your home will now be $105,000 instead of $100,000. However, most gains on the sale of your home are already not taxable, so they won't show up on your tax return even when you sell the home.
It becomes important to keep track of home improvements for the cost basis of your home if you ever rent the home to someone else, you have a home office for your business, you own the home for less than two years before you sell the home, or the gain on the sale of the home exceeds $250,000 ($500,000 if married filing jointly). In those situations, you could possibly be required to report a gain on the sale of your home on your tax return, so you want to include any home improvements over the years in the cost basis in order to reduce the amount of gain reported on the sale.
