Standard Deduction Calculator 2026: guide
The standard deduction is one of the simplest (and biggest) tax breaks most people get. If you do not itemize, the standard deduction is what reduces your income before brackets apply.
What the standard deduction does
The standard deduction reduces your taxable income.
It does not reduce your AGI directly, but it does reduce the income that federal tax brackets apply to.
2026 standard deduction amounts
Standard deduction amounts change most years due to inflation adjustments.
Your exact standard deduction depends on your filing status and whether you qualify for additional amounts (age 65+ or blind).
Additional standard deduction (age 65+ / blind)
If you are age 65 or older, you may qualify for an additional standard deduction.
Married couples can qualify separately for each spouse.
Dependent rules (important)
If someone can claim you as a dependent, your standard deduction is limited.
This is one of the most common reasons people get confused when filing their first return.
