The standard deduction is one of the most valuable tax breaks available to Americans — and the vast majority of people take it. In 2025, it reduces your taxable income by thousands of dollars before a single cent of tax is calculated. Here's what you need to know.
What Is the Standard Deduction?
When the IRS calculates your federal income tax, they don't tax your entire salary. You get to subtract a flat dollar amount from your income first. Whatever's left is your taxable income — the number that actually gets run through the tax brackets.
The standard deduction is that flat amount. It's adjusted for inflation each year and varies by filing status.
2025 Standard Deduction Amounts
| Filing Status | Standard Deduction |
|---|---|
| Single | $14,600 |
| Married Filing Jointly | $29,200 |
| Married Filing Separately | $14,600 |
| Head of Household | $21,900 |
How It Affects Your Paycheck
Your employer accounts for the standard deduction when calculating how much federal tax to withhold from each paycheck. As a single filer earning $60,000, here's what it means:
- Gross annual income: $60,000
- Minus standard deduction: −$14,600
- Taxable income: $45,400
You're taxed on $45,400, not $60,000. At the 10% and 12% brackets, that saves you roughly $1,460 in federal taxes compared to having no deduction at all.
Married couples get double the benefit. Two people earning $60,000 each ($120,000 combined) who file jointly subtract $29,200, leaving $90,800 taxable — significantly less than two single filers would pay combined.
Standard Deduction vs. Itemizing
You can either take the standard deduction or itemize deductions (mortgage interest, charitable donations, state taxes paid, etc.) — whichever is larger. Since the Tax Cuts and Jobs Act nearly doubled the standard deduction in 2018, over 90% of Americans now use the standard deduction rather than itemizing.
Additional Standard Deduction (Age 65+ or Blind)
If you're 65 or older, or legally blind, you get an extra deduction on top of the standard amount:
- Single or Head of Household: additional $1,950 per qualifying status
- Married Filing Jointly: additional $1,550 per qualifying spouse
Does the Standard Deduction Affect State Taxes?
Most states have their own standard deductions for state income taxes, which are usually lower than the federal amounts. Some states require you to use the same method (standard or itemized) that you chose on your federal return.
