Have you filed your federal income tax return for 2011? If not, you might still be able to slim down your tax bill by claiming deductions you may have missed.

What can you deduct? There are two main groups of income tax deductions on a federal tax return. The first group, often referred to as “above- the-line” deductions, are those that may reduce the amount of your adjusted gross income (AGI). Above- the-line deductions include those for IRA contributions, college tuition and fees, and some that you can claim if you’re self-employed.

The second group of deductions fall “below the line”; they’re claimed on Schedule A and attached to your Form 1040. You may be more familiar with these write-offs, which include traditional tax-savers such as deductions for medical expenses, charitable contributions, and mortgage interest payments and property taxes.
