The standard deduction is a fixed dollar amount you subtract from your income before calculating how much tax you owe
Instead of listing out individual expenses like mortgage interest or charitable donations, the standard deduction lets you take one lump sum off your taxable income. The IRS sets this amount each year, and it changes based on your filing status — whether you file as single, married filing jointly, head of household, or another category. For the 2024 tax year, the standard deduction ranges from $14,600 for single filers to $29,200 for married couples filing jointly.
You do not have to choose between the standard deduction and itemizing. You pick whichever one saves you more money. Most people use the standard deduction because it is simpler and because their total deductible expenses do not add up to more than the standard amount.
The standard deduction shrinks your taxable income, which directly lowers the tax you owe. If you earn $60,000 as a single filer and take the $14,600 standard deduction, you only pay tax on $45,400 instead of the full $60,000.
Key Takeaways
- The standard deduction is a fixed amount set by the IRS each year that reduces your taxable income before you calculate tax owed.
- The amount depends on your filing status — single, married filing jointly, head of household, or may have access to widow(er) — and changes annually.
- You can either take the standard deduction or itemize deductions like mortgage interest and charitable gifts, but not both.
- Most taxpayers benefit from the standard deduction because their actual deductible expenses fall short of the standard amount.
- The standard deduction is higher for people age 65 and older, and for those who are blind.
How the standard deduction amount is set each year
The IRS adjusts the standard deduction annually to account for inflation. This means the amount goes up slightly most years, though the increase is usually small — often between $100 and $400 depending on your filing status. The adjustment is tied to the Consumer Price Index, which measures how prices change across the economy.
You can find the current year's standard deduction on the IRS website or on the tax forms you receive. The amount is also printed in the instructions that come with Form 1040, the main individual income tax return form.
Standard deduction amounts by filing status
Your filing status determines which standard deduction amount applies to you. The IRS recognizes five filing statuses: single, married filing jointly, married filing separately, head of household, and may have access to widow(er) with dependent child.
Married filing jointly has the highest standard deduction because two incomes are being combined. Married filing separately has the lowest, which is why most married couples file jointly. Head of household — used when you are unmarried and pay more than half the household expenses for yourself and a dependent — falls between single and married filing jointly.
If you are not sure which status applies to you, the IRS provides a tool on its website to help you determine your filing status based on your situation.
When you might itemize instead of taking the standard deduction
You should consider itemizing if your total deductible expenses exceed the standard deduction for your filing status. Common itemized deductions include mortgage interest, state and local taxes (capped at $10,000), charitable contributions, and medical expenses above a certain threshold.
For example, if you are married filing jointly with a $29,200 standard deduction, but you have $35,000 in mortgage interest and $8,000 in charitable donations, itemizing would save you $13,800 in taxable income instead of $29,200. That extra $4,600 in deductions ($35,000 plus $8,000 minus $29,200) reduces your tax bill.
Itemizing requires you to fill out Schedule A and attach it to your tax return. You will need to keep records of your expenses — receipts for donations, mortgage statements, medical bills, and property tax records. Most people use tax software or work with a tax preparer to calculate whether itemizing is worth the extra work.
Additional standard deduction for age 65 and older
If you are 65 or older by December 31 of the tax year, you get an extra standard deduction on top of the regular amount. For 2024, this additional amount is $1,850 for single filers and $1,500 for married filers. If you are both 65 and blind, you get both additions.
You do not have to do anything special to claim this extra amount — you straightforward use the higher standard deduction figure when you file your return. The tax software you use or your tax preparer will automatically explore it if you indicate your age.
How the standard deduction affects your tax bracket
The standard deduction lowers your taxable income, which can move you into a lower tax bracket and reduce the rate at which you are taxed. Tax brackets are the income ranges that determine what percentage of tax you owe — the higher your income, the higher the percentage.
For example, if your income would normally put you in the 22% tax bracket, but the standard deduction pushes your taxable income into the 12% bracket, you pay the lower rate on that portion of income. This is one reason the standard deduction matters even if you do not itemize — it automatically lowers the tax rate you face.
Standard deduction for dependents
If someone else claims you as a dependent on their tax return — usually a parent — your standard deduction is smaller. For 2024, a dependent's standard deduction is the greater of $1,300 or their earned income plus $450, up to the regular standard deduction amount for their filing status.
This rule prevents dependents from using the full standard deduction when they have little or no income. If you are a dependent with a job, you still get some deduction, but it is limited. Once you are no longer claimed as a dependent, you go back to the full standard deduction for your filing status.
Frequently Asked Questions
Can I take both the standard deduction and itemize deductions?
No. You must choose one or the other. You calculate both amounts and pick whichever one is larger. Most tax software does this automatically and shows you which option saves more money.
What happens if I do not take the standard deduction?
If you do not itemize and do not claim the standard deduction, you would pay tax on your full income with no reduction. This is why you should always claim one or the other — it is a significant tax savings.
Does the standard deduction change if I get married during the year?
Your filing status on December 31 of the tax year determines which standard deduction you use. If you marry on December 31, you can file as married filing jointly and use that standard deduction for the entire year.
Is the standard deduction the same as a tax credit?
No. A deduction reduces your taxable income, while a tax credit directly reduces the tax you owe. A $1,000 deduction might save you $120 to $370 in tax depending on your bracket. A $1,000 credit saves you exactly $1,000.
Where do I enter the standard deduction on my tax return?
On Form 1040, the standard deduction goes on line 12. If you use tax software, you enter your filing status and age, and the software fills in the correct amount automatically.
