Itemized Deductions

Itemized Deductions are specific eligible expenses that taxpayers can subtract from their adjusted gross income to reduce taxable income, claimed individually on Schedule A instead of taking the standard deduction. Taxpayers must choose between itemizing deductions or claiming the standard deduction, selecting whichever method provides the greater tax benefit. Since the Tax Cuts and Jobs Act significantly increased standard deduction amounts starting in 2018, fewer taxpayers benefit from itemizing than in previous years.

Itemized deductions fall into several major categories reported on Schedule A. Medical and dental expenses exceeding 7.5% of your adjusted gross income are deductible, including payments for diagnosis, treatment, prevention, equipment, and qualified long-term care. State and local taxes (SALT) including real estate taxes, personal property taxes, and either state income taxes or general sales taxes are deductible up to a combined $10,000 limit ($5,000 if married filing separately). Home mortgage interest on acquisition debt up to $750,000 ($1 million for loans originated before December 15, 2017) is deductible for first and second homes.

Charitable contributions to qualified organizations are deductible up to specified percentage limits based on your adjusted gross income, typically 60% for cash donations to public charities and 30% for capital gain property. Casualty and theft losses are generally only deductible for losses in federally declared disaster areas. Gambling losses can offset gambling winnings but cannot exceed winnings reported.

You should itemize when your total qualifying deductions exceed the standard deduction for your filing status: $14,600 for single filers, $29,200 for married filing jointly, and $21,900 for heads of household (2024 amounts). Homeowners with mortgages and property taxes, those with significant medical expenses, and generous charitable donors are most likely to benefit from itemizing.

Itemizing requires maintaining detailed records and receipts documenting each expense. Tax software automatically calculates whether itemizing or taking the standard deduction provides greater tax savings. Some states allow itemized deductions even when taking the federal standard deduction, requiring separate analysis for state returns.
