The standard tax deduction is a fixed dollar amount you can subtract from your income before calculating how much federal income tax you owe
Instead of listing out individual expenses (mortgage interest, medical bills, charitable donations), you take one lump-sum deduction. The IRS sets this amount each year, and it changes based on inflation. For the 2024 tax year, the standard deduction ranges from $14,600 to $29,200 depending on your age and filing status — a single person under 65 gets less than a married couple filing jointly, and anyone 65 or older gets a higher amount.
You do not have to choose between the standard deduction and itemizing. The IRS lets you use whichever one results in a lower tax bill. Most people use the standard deduction because their total deductible expenses do not add up to more than the standard amount. If you have significant mortgage interest, state taxes, or charitable donations, itemizing might save you more money — but that is a separate calculation you would make on Schedule A.
Key Takeaways
- The standard deduction is a set dollar amount that reduces your taxable income, and the IRS adjusts it each year for inflation.
- Your filing status (single, married filing jointly, head of household, etc.) and age determine which standard deduction amount applies to you.
- You can use the standard deduction or itemize deductions, but not both — choose whichever lowers your tax bill.
- If someone else claims you as a dependent, your standard deduction is reduced or eliminated, depending on your income and relationship to that person.
Standard deduction amounts by filing status and age
The IRS publishes new standard deduction amounts each January for the tax year you are filing. These amounts apply to returns filed in 2025 for the 2024 tax year:
| 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 | $27,650 |
| may have access to Widow(er) | $29,200 | $30,750 (one spouse 65+) / $32,300 (both 65+) |
These amounts increase each year. For 2025 tax returns (filed in 2026), the amounts will be higher. You can find the current year's standard deduction on the IRS website or on the instructions that come with your tax form.
When you cannot use the standard deduction
Most people can use the standard deduction, but a few situations prevent it. If you are a nonresident alien or a dual-status alien for the tax year, you generally cannot use the standard deduction. The same applies if you file a short tax year because you changed your accounting method.
If someone else claims you as a dependent on their tax return, your standard deduction is limited. If you are a dependent with earned income (wages from a job), your standard deduction is the greater of $1,300 or your earned income plus $450, but it cannot exceed the full standard deduction for your filing status. If you have only unearned income (interest, dividends, capital gains), your standard deduction is $1,300 for 2024. This rule prevents dependents from using the full standard deduction that independent filers receive.
Standard deduction versus itemizing deductions
You have the right to itemize deductions instead of taking the standard deduction. Itemizing means you list out specific expenses on Schedule A and add them up. Common itemized deductions include mortgage interest, state and local taxes (capped at $10,000), charitable donations, and medical expenses above a certain threshold.
Itemizing makes sense only if your total itemized deductions exceed your standard deduction. For example, if you are single and your standard deduction is $14,600, you would need more than $14,600 in itemized deductions to benefit from itemizing. If your itemized deductions total only $12,000, you are better off taking the standard deduction.
The Tax Cuts and Jobs Act of 2017 roughly doubled the standard deduction, which means fewer people itemize now than before. Most filers find the standard deduction simpler and more valuable. You do not need receipts or documentation to claim the standard deduction — you simply enter the amount on your tax return.
How the standard deduction affects your tax bill
The standard deduction reduces your taxable income dollar-for-dollar. If your gross income is $50,000 and your standard deduction is $14,600, your taxable income becomes $35,400. You then pay tax on that $35,400 using the tax brackets for your filing status.
A larger standard deduction means a smaller taxable income and a smaller tax bill. This is why the IRS gives older filers a higher standard deduction — it recognizes that people 65 and older often have lower incomes and provides some tax relief. The standard deduction also increases each year with inflation, so your deduction grows even if your income stays the same.
Filing status and how it determines your standard deduction
Your filing status is one of the main factors that determines which standard deduction amount you receive. The IRS recognizes five filing statuses: Single, Married Filing Jointly, Married Filing Separately, Head of Household, and may have access to Widow(er). Your status on December 31 of the tax year is the status you use for that entire year.
Married Filing Jointly produces the highest standard deduction, which is why many married couples benefit from filing together. Head of Household (for unmarried people who pay more than half the household expenses for themselves and a dependent) gets a middle-range deduction. Single and Married Filing Separately get the lowest amounts. If you are unsure which status applies to you, the IRS provides a worksheet in the instructions to Form 1040.
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 reduced. If you have earned income, your standard deduction is the greater of $1,300 or your earned income plus $450, up to the full standard deduction for your filing status. If you have only unearned income, your standard deduction is $1,300 for 2024.
Do I need receipts to claim the standard deduction?
No. The standard deduction is a set amount you enter on your return — you do not need to document or prove anything. Receipts are only required if you itemize deductions on Schedule A.
What happens if my income is below the standard deduction?
You still may need to file a tax return, depending on your income level and filing status. The IRS has filing thresholds that determine whether you must file. Even if you are not required to file, you may want to file anyway to claim a refundable tax credit like the Earned Income Tax Credit.
Does the standard deduction change every year?
Yes. The IRS adjusts the standard deduction each year for inflation. The amounts are published in January for the tax year you are filing. You can find the current amounts on the IRS website or in the instructions to Form 1040.
Can I claim both the standard deduction and itemized deductions?
No. You must choose one or the other. The IRS will allow you to use whichever method results in a lower tax bill, but you cannot use both on the same return.
