The standard tax deduction provides a flat reduction in taxable income that most Americans can claim without itemizing expenses. For 2025, the IRS increased deduction amounts across all filing statuses.
Single filers get a $14,600 standard deduction in 2025, up from $14,250 in 2024. Married couples filing jointly receive $29,200, compared to $28,550 previously. Head of household filers claim $21,900 versus $21,400 last year. Married individuals filing separately get $14,600 each.
These annual increases track inflation and reflect adjustments the IRS makes using a specific formula. The deduction essentially reduces your taxable income before tax rates apply. If your income falls below the standard deduction, you typically owe no federal income tax at all.
For 2026, expect further increases. The IRS typically announces these figures in late October or early November before the tax year begins.
The standard deduction matters most when deciding whether to itemize instead. Itemizing means tracking deductible expenses like mortgage interest, property taxes, charitable donations, and medical costs. Most taxpayers find the standard deduction easier and more beneficial. You must choose one or the other, not both.
Higher earners with significant deductible expenses sometimes benefit from itemizing. Wealthy homeowners in high-tax states like New York and California frequently itemize because state and local tax (SALT) deductions, plus mortgage interest, exceed the standard amount.
Age changes the picture too. Taxpayers 65 and older get an extra standard deduction boost. Single filers 65 or older claim $18,150 in 2025. Married couples filing jointly with at least one spouse 65 or older receive $30,700. This additional amount helps seniors with lower incomes avoid tax filing requirements
