Common tax deductions are specific expenses the IRS allows you to subtract from your taxable income, reducing what you owe. These include mortgage interest, state taxes paid, medical expenses, and charitable donations.
Deductions lower your taxable income, which reduces your tax bill. For example, if you earn $50,000 and claim $5,000 in deductions, you'll only pay taxes on $45,000. The U.S. tax system offers two main ways to claim deductions: the standard deduction (a flat amount based on filing status) or itemized deductions (listing individual eligible expenses).
The IRS recognizes several categories of deductions. Here are the most common:
Tax deductions apply to federal income taxes and sometimes state taxes. The IRS allows them to encourage certain behaviors, like homeownership, charitable giving, and retirement saving. For instance, mortgage interest deductions make buying a home more affordable, while deductions for business expenses support entrepreneurship.
One common misconception is that all deductions reduce taxable income equally. However, above-the-line deductions are more valuable because they lower your adjusted gross income (AGI), which affects eligibility for other tax benefits. Itemized deductions, while useful, only reduce taxable income after AGI.
Suppose you're a single filer earning $60,000 in 2023. You paid $3,000 in mortgage interest, $2,000 in state taxes, and $5,000 in medical expenses (exceeding the 7.5% threshold). Instead of taking the $13,850 standard deduction, you'd itemize and deduct $10,000 ($3,000 + $2,000 + $5,000). This lowers your taxable income to $50,000, saving you hundreds in taxes.
Another mistake is missing deductions entirely. The IRS reports that millions of taxpayers overpay by failing to claim eligible deductions. To avoid this, track expenses throughout the year and consult the IRS's Publication 17 for guidance.
