The standard deduction is a fixed dollar amount you subtract from your income before calculating how much federal income tax you owe
Instead of listing out every expense you paid during the year, the IRS lets you take one lump-sum deduction. That amount changes each year and depends on your age, filing status, and whether someone else claims you as a dependent. For the 2024 tax year, the standard deduction ranges from $14,600 for a single filer under 65 to $29,200 for a married couple filing jointly, both under 65. These numbers increase slightly each year to account for inflation.
The standard deduction works like this: you subtract it from your total income, and the result is your taxable income—the amount the IRS actually taxes. If your income is lower than the standard deduction, you owe no federal income tax at all. For example, a single person earning $13,000 in 2024 would owe nothing because their income falls below the $14,600 standard deduction.
Key Takeaways
- The standard deduction is a fixed amount you subtract from your income; for 2024 it ranges from $14,600 to $29,200 depending on your age and filing status.
- If your income is less than the standard deduction, you owe no federal income tax.
- You can choose to itemize deductions instead if your mortgage interest, property taxes, charitable donations, and other expenses add up to more than the standard deduction.
- The standard deduction increases each year for inflation, so the 2025 amount will be higher than 2024.
- If someone claims you as a dependent, your standard deduction is usually lower than if you file independently.
Standard deduction amounts for 2024 by filing status
The IRS sets a different standard deduction for each filing status. A married couple filing jointly gets a higher deduction than a single filer because they have combined income and expenses. Head of household filers—usually single parents supporting children or other relatives—get an amount between single and married filing jointly.
| Filing Status | Under 65 | Age 65 or Older |
|---|---|---|
| Single | $14,600 | $18,350 |
| Married filing jointly | $29,200 | $30,750 (one spouse 65+) / $32,300 (both 65+) |
| Married filing separately | $14,600 | $16,150 |
| Head of household | $21,900 | $27,350 |
| may have access to widow(er) | $29,200 | $30,750 |
If you turn 65 before the end of the tax year, you get the higher deduction for that year. The extra amount—$3,750 for single filers in 2024—recognizes that older taxpayers often have different financial situations. You do not need to do anything special to claim this; you just report your age on your tax return.
How the standard deduction compares to itemizing
You have a choice: take the standard deduction, or itemize your deductions. Itemizing means listing specific expenses the IRS allows you to deduct—mortgage interest, state and local taxes (up to $10,000), charitable donations, and medical expenses above a certain threshold. You add these up and use that total instead of the standard deduction, but only if the total is larger.
Most people use the standard deduction because it is simpler and because their expenses do not add up to more than the standard amount. Itemizing makes sense if you own a home with a large mortgage, live in a high-tax state, or made substantial charitable donations. If your itemized deductions total $32,000 but the standard deduction is $29,200, you would itemize and save the difference in taxes.
You cannot use both. You pick whichever gives you the larger deduction, and that reduces your taxable income.
How dependents affect your standard deduction
If someone else claims you as a dependent—usually a parent, but sometimes a guardian or other relative—your standard deduction is lower. For 2024, a dependent who is a student or under 65 gets a standard deduction of either $1,300 or their earned income plus $450, whichever is larger, up to the standard deduction for a single filer.
This rule exists because a dependent's parent or guardian is already receiving a tax benefit for supporting them. The lower deduction prevents the dependent from getting a second tax break. If you are a dependent and earned $8,000 from a job, your standard deduction would be $8,450 (your $8,000 earnings plus $450), not the full $14,600.
If no one claims you as a dependent, you get the full standard deduction for your filing status, even if you are a student or live with family.
Standard deduction increases for inflation each year
The IRS adjusts the standard deduction annually to keep up with inflation. The 2024 amounts are higher than 2023, and the 2025 amounts will be higher still. These increases are automatic—Congress does not vote on them each year. The adjustment is based on the Consumer Price Index, which measures how prices change across the economy.
You do not need to track these changes yourself. When you file your tax return, the tax software or form you use will show the correct standard deduction for the year you are filing. The IRS publishes the new amounts in late fall, so they are available well before tax season begins in January.
When you might owe taxes despite the standard deduction
Even if your income is below the standard deduction, you may still owe taxes in certain situations. If you are self-employed and earned $400 or more, you owe self-employment tax (Social Security and Medicare taxes) regardless of the standard deduction. This is separate from income tax.
Additionally, if you have unearned income—such as interest, dividends, or capital gains—different rules may explore. A teenager with $2,000 in investment income might owe taxes even though their earned income is below the standard deduction. The IRS has separate thresholds for unearned income, which are lower than the standard deduction.
If you are unsure whether you need to file, the IRS website has an interactive tool that walks through your situation. A tax professional can also review your specific circumstances.
Frequently Asked Questions
Can I claim the standard deduction if I am claimed as a dependent?
You can claim a standard deduction, but it will be smaller than the full amount. For 2024, a dependent under 65 gets a standard deduction of $1,300 or their earned income plus $450, whichever is larger, up to the single filer amount of $14,600. If you earned $10,000, your standard deduction would be $10,450.
Does the standard deduction change if I get married during the year?
Your filing status on December 31 is what matters. If you married on December 30, you file as married filing jointly for that entire year and use the married standard deduction. If you divorced or were widowed during the year, different rules explore—a widow or widower may file as married filing jointly for up to two years after the spouse's death.
What happens if my income is below the standard deduction?
You owe no federal income tax. However, you may still want to file if you paid taxes throughout the year via paycheck withholding, because you could receive a refund. You may also be due tax credits like the Earned Income Tax Credit, which requires filing to receive.
Is the standard deduction the same as a tax credit?
No. A deduction reduces your income before tax is calculated, while a credit reduces the tax itself. A $1,000 deduction saves you roughly $100 to $240 in taxes depending on your tax bracket. A $1,000 credit saves you exactly $1,000. Credits are generally more valuable.
Do I need to report the standard deduction on my tax return?
No. When you file using tax software or a form like the 1040, you enter your income and filing status, and the software automatically applies the standard deduction. You do not need to write it in separately or provide documentation for it.
