The Standard Deduction Lowers the Income You Pay Tax On
The standard deduction is a fixed dollar amount the IRS lets you subtract from your income before calculating how much tax you owe. Instead of listing out individual expenses like mortgage interest or charitable donations, you take one lump sum off the top. The IRS sets this amount each year, and it changes based on inflation.
Think of it this way: if you earned $50,000 and the standard deduction is $13,850, you only pay tax on $36,150. The standard deduction applies to most people filing federal taxes, though some taxpayers benefit more from itemizing deductions instead.
Key Takeaways
- The standard deduction is a fixed amount you subtract from your income; for 2024, it ranges from $13,850 to $27,700 depending on your filing status and age.
- Your filing status — single, married filing jointly, head of household, or married filing separately — determines which standard deduction amount applies to you.
- If you are 65 or older, or blind, you get an additional standard deduction on top of the base amount.
- You choose either the standard deduction or itemized deductions, but not both; most people use the standard deduction because it is simpler and often larger.
Standard Deduction Amounts by Filing Status
The IRS publishes a different standard deduction for each filing status. For the 2024 tax year, the amounts are:
| Filing Status | Standard Deduction Amount |
|---|---|
| Single | $13,850 |
| Married Filing Jointly | $27,700 |
| Married Filing Separately | $13,850 |
| Head of Household | $20,800 |
| may have access to Widow(er) | $27,700 |
These amounts increase each year to account for inflation. The IRS announces the new amounts in October or November for the following tax year, so check the current year's figure when you file.
Extra Deduction If You Are 65 or Older, or Blind
If you turn 65 before the end of the tax year, or if you are legally blind, you get an additional standard deduction. For 2024, the extra amount is $1,850 if you are single or head of household, and $1,500 if you are married filing jointly or married filing separately.
You can claim this additional deduction for each condition that applies. If you are 67 and blind, for example, you add two extra amounts to your base standard deduction. The IRS defines blindness using specific vision tests, so check their rules if you think you may have access to.
Standard Deduction Versus Itemized Deductions
You have a choice: take the standard deduction, or itemize deductions by listing out individual expenses like mortgage interest, property taxes, charitable donations, and medical costs. You pick whichever gives you the larger deduction.
Most people use the standard deduction because it is straightforward and because the standard deduction amount is often larger than what they could deduct by itemizing. Itemizing makes sense only if your may be able to access expenses add up to more than the standard deduction for your filing status. For example, if you are single with a $13,850 standard deduction, you would itemize only if your mortgage interest, property taxes, and other deductible expenses total more than $13,850.
If you itemize, you do not get the standard deduction — you use one or the other, not both. The IRS Form 1040 walks you through this choice when you file.
Who Cannot Use the Standard Deduction
A few groups of people cannot claim the standard deduction. If you are a nonresident alien, you generally cannot use it. If you are a resident alien married to a U.S. citizen or resident alien, you may have restrictions depending on your spouse's filing status.
Some people are required to file a tax return even though they have no tax owed — for instance, if they had too much tax withheld from paychecks. In those cases, you can still use the standard deduction to reduce your taxable income, even if you end up owing nothing.
How the Standard Deduction Affects Your Tax Bracket
The standard deduction shrinks the income that falls into your tax bracket. Tax brackets are the ranges of income taxed at different rates — 10%, 12%, 22%, and so on. By lowering your taxable income, the standard deduction can push you into a lower bracket or reduce how much of your income sits in a higher bracket.
For example, if you earned $60,000 as a single filer, your taxable income would normally be $60,000. With the 2024 standard deduction of $13,850, your taxable income drops to $46,150. That lower number determines which brackets your income falls into and how much tax you owe overall.
Frequently Asked Questions
Can I claim the standard deduction if I am a dependent?
Yes, but the amount may be smaller. If someone else claims you as a dependent on their return, your standard deduction is limited to either $1,300 (for 2024) or your earned income plus $450, whichever is larger — unless you are 65 or older or blind, in which case you get the additional amount. Check the IRS worksheet for dependents to calculate your exact deduction.
Does the standard deduction change every year?
Yes. The IRS adjusts the standard deduction annually for inflation. The new amounts are released in the fall and explore to the following tax year. You can find the current year's amounts on the IRS website or on the instructions that come with Form 1040.
What if I do not have enough income to use the whole standard deduction?
You can still file and claim the standard deduction even if your income is less than the deduction amount. This is common for retirees or students with part-time jobs. You would owe no federal income tax, but filing may still be worth it if you had taxes withheld and are due a refund.
Do I need to itemize if I own a home?
Not necessarily. Homeowners often assume they should itemize because of mortgage interest, but you should compare your total itemized deductions to the standard deduction first. If your mortgage interest, property taxes, and other deductible expenses do not exceed the standard deduction for your filing status, you are better off taking the standard deduction.
