For the 2025 tax year, most major tax sources agree that the federal standard deduction has been increased to $15,750 for single filers and married filing separately, $31,500 for married filing jointly and qualifying surviving spouses, and $23,625 for heads of household. These updated amounts reflect both the IRS’s regular inflation adjustment and additional changes enacted under new federal tax legislation that applied starting with the 2025 tax year.

These figures line up across several 2025-focused tax explainers and fact‑checks that summarize the post‑legislation adjustment to the standard deduction schedule. Earlier IRS inflation tables for 2025 had slightly lower preliminary amounts, but later updates and commentary note the higher numbers now widely used for planning.

Extra amounts for age 65+ or blind

On top of the base standard deduction, taxpayers who are 65 or older or blind can generally claim an additional standard deduction amount. For 2025, common tax guides report that this extra amount is around $2,000 for single and head of household filers and about $1,600 per qualified spouse for married filing jointly, married filing separately, and qualifying surviving spouses, effectively raising the total deduction for those who qualify.

How this affects your 2025 return

For most people filing 2025 federal taxes (returns due in 2026), the increased standard deduction will reduce taxable income compared with using the older 2024 amounts, all else equal. However, it can still be worth comparing the standard deduction to potential itemized deductions—such as mortgage interest, state and local taxes within caps, and charitable contributions—to see which approach yields the lower overall tax bill.
