Can the capital improvements that I made to my home this year, such as new roof, new air conditioner, new hard wood floors, and new gutters, be tax deductible?

[AbrahamT]

It depends if it is for personal use, then the answer is ccertainly no. If however you are using a portion of your house to rent to other tenants and are reporting rental income and expenses on a Sch E for example, them you may take those a portion of those expenses relating to those expenses either as repairs or depreciate over the life of these expenses called Leasehold Improvements usually over 27.5 years. You may also have the option to to take 179 depreciation for the full amount under certain conditions.  However, you definitely want to keep a record of these improvements when you decide to sell your house later in the future so you can add them to the cost basis of the house down the road thus decreasing you net gain from the sale.
