What is the Standard Deduction
The standard deduction is a fixed dollar amount you can subtract from your adjusted gross income before calculating your tax bill — no receipts required. It's the most common deduction method, used by roughly 90% of taxpayers.
The standard deduction is a flat dollar amount set by the IRS that you can subtract from your Adjusted Gross Income (AGI) to arrive at your taxable income — the income on which your actual tax bill is calculated. It requires no receipts, no documentation, and no itemization. You simply claim it based on your filing status.
Taxable Income = AGI − Standard Deduction
The standard deduction is the simpler alternative to itemizing deductions. Because the Tax Cuts and Jobs Act of 2017 nearly doubled the standard deduction, roughly 90% of filers now use it rather than itemizing.
2025 Standard Deduction Amounts
| Filing Status | 2025 Standard Deduction |
|---|---|
| Single | $15,000 |
| Married Filing Jointly | $30,000 |
| Married Filing Separately | $15,000 |
| Head of Household | $22,500 |
These amounts are adjusted annually for inflation.
Additional Standard Deduction for Age and Blindness
Taxpayers who are 65 or older or legally blind are entitled to an additional standard deduction on top of the base amount:
| Filing Status | Additional Amount (2025) |
|---|---|
| Single (65+ or blind) | $2,000 per qualifying status |
| Married Filing Jointly (65+ or blind) | $1,600 per qualifying status per spouse |
A single filer who is 65 or older and blind would add $4,000 to the base $15,000 — claiming a total of $19,000.
Standard Deduction vs. Itemized Deductions
You can only choose one method each year. You should itemize if your eligible itemized deductions exceed your standard deduction. Common itemized deductions include:
- Mortgage interest
- State and local taxes (SALT, capped at $10,000)
- Charitable contributions
- Medical expenses exceeding 7.5% of AGI
For most middle-income filers, the standard deduction is larger. Taxpayers who own expensive homes, pay high state income taxes, or have substantial charitable giving are most likely to benefit from itemizing.
Who Cannot Take the Standard Deduction
A few filers are not allowed to claim the standard deduction and must itemize:
- A married taxpayer filing separately whose spouse itemizes
- Nonresident aliens (in most cases)
- Estates, trusts, and common trust funds
- Taxpayers with short tax years due to an accounting period change
Standard Deduction and Tax Planning
The standard deduction is inflation-adjusted each year, so simply taking it requires no planning. However, some taxpayers use a strategy called deduction bunching — concentrating two years of charitable donations into one year, for example — to push itemized deductions above the standard deduction threshold every other year, alternating between itemizing and taking the standard deduction.
The standard deduction gets subtracted from AGI on IRS Form 1040, and it appears on line 12. If you take the standard deduction, you skip Schedule A entirely.
