The standard tax deduction lets you reduce your taxable income without itemizing expenses. The IRS raises this amount annually for inflation. For 2025, the standard deduction climbs to $14,600 for single filers and $29,200 for married couples filing jointly. That's up from $13,850 and $27,700 in 2024.
If your income falls below the standard deduction, you owe no federal income tax. If it exceeds that threshold, you pay tax only on the amount above it. This matters because most taxpayers claim the standard deduction rather than itemize. Itemizing requires tracking mortgage interest, property taxes, charitable donations, and medical expenses. The standard deduction skips that paperwork.
For seniors, the standard deduction increases further. Single taxpayers age 65-plus get an extra $1,850, bringing their total to $16,450. Married filers both age 65-plus receive an additional $1,500 each, totaling $32,200. Head of household filers age 65-plus get $4,200 more than the standard $21,900.
The annual increase protects your purchasing power. Without inflation adjustments, wage growth would push more people into higher tax brackets even when their actual wealth stayed flat. This creep, called bracket inflation, would force middle-class earners to pay more.
Your filing status determines which deduction applies. Single, married filing jointly, married filing separately, and head of household each have different limits. Dependents follow a separate formula tied to their earned income.
If you itemize instead of taking the standard deduction, you'll need receipts and documentation for every deduction. The standard deduction provides relief from that burden for most households. You benefit automatically when you file, no paperwork required.
