One of the drawbacks to low mortgage rates is that the total interest and property taxes paid for the year may be lower than the standard deduction. A little planning might be able to help you at least every other year.
Most homeowners know they can deduct their qualified mortgage interest and property taxes on their Schedule A of their 1040 tax return or to take the standard deduction if it is greater. See Your Deduction...Your Choice.
Deductions are taken in the year that they're actually paid. If a homeowner paid their 2012 property taxes in 2013, they would not be deductible on their 2012 tax return. Then, if the 2013 property taxes were paid in 2013, both the 2012 and 2013 taxes could be deducted on the 2013 Schedule A.
By delaying the payment of the 2012 taxes until 2013, the combination of the 2012 and 2013 taxes might exceed the 2013 standard deduction and provide a higher deduction.
Other Schedule A expenses such as charitable contributions and medical expenses may be bunched also. From a practical standpoint, since most mortgage payments are due monthly, the mortgage interest would not be bunched.
This information should be discussed with your tax advisor to see how it might apply to your individual situation. The key is you must be aware of the strategy early to be able to use it.
