Many taxpayers can lower their taxable income by itemizing deductions, which in turn lowers tax liability. Itemized deductions reduce tax burdens for taxpayers with decreased ability to pay taxes, such as those experiencing a catastrophic loss, or for taxpayers who spent funds on activities the tax code deems worthwhile, such as contributing to charity. In recent years, the largest itemized deductions were those for mortgage interest paid, state and local taxes paid, and charitable contributions.
