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 deductions (mortgage interest, charitable donations, medical expenses), most people 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 is $14,600 for single filers, $29,200 for married couples filing jointly, and $21,900 for heads of household. These numbers shift annually.
You do not have to itemize deductions to use the standard deduction — you simply claim it on your return. The IRS assumes you will take whichever option saves you more money: the standard deduction or itemizing your actual expenses. 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.
Key Takeaways
- The standard deduction is a fixed amount set by the IRS each year that reduces your taxable income, and you do not have to prove or list specific expenses to claim it.
- The amount you can deduct depends on your filing status (single, married, head of household) and your age — people 65 and older get a higher standard deduction.
- You choose either the standard deduction or itemized deductions, not both; most taxpayers use the standard deduction because it requires less paperwork and often saves more money.
- If your income is very low, you may not owe any tax at all once you subtract the standard deduction, even if you had earnings during the year.
How the standard deduction reduces what you owe
The standard deduction works by lowering your taxable income. If you earned $50,000 and your standard deduction is $14,600, you only pay tax on $35,400. The tax brackets then determine your actual tax bill based on that reduced amount.
This matters because the lower your taxable income, the less tax you owe. A larger deduction means a smaller tax bill. That is why the IRS raises the standard deduction each year — to keep pace with inflation and prevent people from paying tax on income that has lost purchasing power.
Standard deduction amounts by filing status and age
| 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+) |
| Head of Household | $21,900 | $27,650 |
| may have access to Widow(er) | $29,200 | $30,750 |
These amounts are for the 2024 tax year. The IRS publishes updated amounts each October or November for the following year. If you turn 65 on or before December 31 of the tax year, you may have access to for the higher amount.
Dependents have a different rule. If someone else claims you as a dependent on their return, your standard deduction is limited to the greater of $1,300 or your earned income plus $450 (up to the normal standard deduction for your filing status). This prevents dependents from claiming the full standard deduction when they have little or no income.
Standard deduction versus itemizing deductions
You have two paths: take the standard deduction, or itemize your deductions. Itemizing means adding up may have access to expenses like mortgage interest, state and local taxes (capped at $10,000), charitable donations, and medical expenses above a threshold. You report these on Schedule A and subtract the total from your income.
Most people use the standard deduction because their itemized deductions do not exceed it. For example, if you are single with a standard deduction of $14,600, you would only benefit from itemizing if your deductible expenses total more than $14,600. If they total $12,000, you are better off taking the standard deduction and saving yourself the paperwork.
The Tax Cuts and Jobs Act of 2017 roughly doubled the standard deduction, which pushed even more people toward using it instead of itemizing. You cannot claim both — the IRS requires you to choose one method.
Who might not use the standard deduction
Some people are not allowed to claim the standard deduction. If you are a nonresident alien or a dual-status alien during the year, you generally cannot use it. Married people filing separately where one spouse itemizes must also itemize, even if the standard deduction would save them more money.
Beyond those restrictions, some people choose not to use it because itemizing saves them more. This is common for homeowners with high mortgage interest and property taxes, people with large charitable donations, or those with significant medical expenses. A tax professional can help you calculate which method saves more money in your specific situation.
How to claim the standard deduction on your return
If you file on paper using Form 1040, you enter the standard deduction amount on the line labeled "Standard deduction or itemized deductions." You do not need to attach anything or provide documentation — the IRS trusts that you know your filing status and age.
If you use tax software or file electronically, the program usually fills in the standard deduction automatically based on the information you provide about your filing status and age. You can override it if you want to itemize instead, but most people leave it as is.
You do not report the standard deduction to your employer or on any other form during the year. It only appears on your tax return itself, when you calculate your taxable income.
Frequently Asked Questions
Does taking the standard deduction affect my other tax credits?
No. The standard deduction and tax credits are separate. Credits like the Earned Income Tax Credit or Child Tax Credit are not reduced because you took the standard deduction. Credits reduce your tax bill directly, while the deduction reduces the income you are taxed on.
Can I claim the standard deduction if I am claimed as a dependent?
You can claim a reduced standard deduction. If you are a dependent with earned income, your standard deduction is the greater of $1,300 or your earned income plus $450, up to the normal limit for your filing status. If you have no earned income, your standard deduction is $1,300.
What happens if my income is below the standard deduction?
You may not owe any federal income tax. If your income is less than the standard deduction for your filing status, you have no taxable income and therefore no tax liability. You may still want to file if you are owed a refund from taxes withheld or to claim refundable credits.
Do state and local taxes affect my standard deduction?
No. The standard deduction is a federal amount only. State income tax works separately and has its own rules. Some states have their own standard deduction amounts, and some do not tax income at all.
Will the standard deduction change next year?
Yes, it changes annually for inflation. The IRS announces the new amounts in October or November for the following tax year. You can find current and upcoming amounts on the IRS website.
