Depending on your personal tax situation, the interest you pay on your mortgage may be tax deductible to you. Those who itemize deductions and are in a high tax bracket may receive a substantial deduction from the mortgage interest they pay. For those in lower brackets, with a minimal amount of mortgage interest, it may be negligible.
The IRS states that, “In most cases, you can deduct all of your home mortgage interest. How much you can deduct depends on the date of the mortgage, the amount of the mortgage, and how you use the mortgage proceeds.” This article gives you the details on each of those criteria. Believe it or not, in many cases even the interest on a boat or motor home can be considered tax deductible mortgage interest.
This is a link to a mortgage calculator that can help you estimate the amount of tax benefit that may be generated by tax deductible mortgage interest.
In general, the higher your tax bracket, the greater the potential benefit of a mortgage. Once retired, your tax bracket is likely to be lower. Evalutate the tax impact of your mortgage both before and after retirement; this can help you decide if you should pay off your mortgage once retired.
This example will show you how to compare the after-tax return on your investments with the after-tax cost of your mortgage, assuming your mortgage interest is tax deductible.
