I just came across this article the other day and wanted to share it. Clients (past, present and future) regularly consult with me on how much value they may see in a home improvement project when they go to sell their home. The answer is often a double-edged sword, as I remind them that improvements that increase the value of a home can also increase the owner's tax liability. Your capital gains tax liability (based on how much more your sale price is than your buying price was) is complex, but can often be offset by the cost of the improvements you made to your home while you owned it. My advice -- always -- is, whatever you do, save receipts.
I love when a reputable news source like the New York Times runs a piece like this, mostly because the information is so comprehensive - containing valuable links and answering almost every question that may come up.
For example, simply the listing of what we can deduct is very helpful: "...decks and patios; landscaping, including sprinkler systems; pools; a new roof or siding; insulation; and kitchen remodeling. Some smaller and perhaps surprising things are there, too: installation of utility services, which could include any fiber charges from Verizon for FiOS or money you paid to the person who hard-wired your Apple TV to your cable modem. Each additional electrical outlet should count, too. Also, you can add in many legal, title and recording fees (plus transfer and certain other taxes) from your closing."
I especially like the suggestion to photocopy "thermal receipts," as they can fade over time.
