The tax write-offs on roofing projects come and go with the whims of Congress. As new concepts begin to catch the ears of our representatives, products will begin to enter the market and tax savings will be attached to their purchases for their uses.
There is no sure way of knowing all or any of the parameters and limitations for the tax write-off benefits unless you continually check with your CPA or tax preparer. Part of their job is to stay abreast of the deductions for capital improvements and any other incentive programs that offer you tax savings. Usually these kinds of write-offs require you to be using multiple itemized forms to amount to large overall savings. Short forms won't help you much at all if any. Since Florida does not have a state income tax, the only benefits that can be realized from these incentive programs must come directly out of Washington, DC and claimed on your federal tax return. If they are substantial, by all means utilize them.
Most of the incentive programs all are enacted with a sunset clause that ends the program before you are able to capitalize in time for them. When discussing the available benefits with your tax preparer, always discuss the time limitations so that you will not get caught short and lose out.
