Taxpayers can deduct either their standard deduction or itemized deductions from their adjusted gross income (AGI) to calculate their taxable income. The key being one or the other, not both.
The standard and itemized deductions are in essence a layer of tax-free money the government allows taxpayers for cost-of-living expenses. Generally, taxpayers deduct the amount that gives them the lowest tax, which is usually the higher amount. However, there are instances when they are required to use one method over the other.
Standard deduction amounts are set amounts that are increased annually for inflation. The amounts vary by filing status, age and blindness. Taxpayers age 65 or older and/or blind receive an additional amount to add to their regular standard deduction.
For determining age, taxpayers are considered age 65 the day before their birthday. For example, Tillie turns age 65 on Jan. 1, 2026. For tax purposes, Tillie is considered age 65 on Dec. 31, 2025, and is eligible for the increased standard deduction in 2025.
In general, because the standard deduction amounts are known amounts, taxpayers with income levels below their standard deduction generally do not have a filing obligation. Where itemized deductions are not known amounts, causing taxpayers who itemize to have a filing obligation.
For 2025 and 2024 the standard deduction per filing status is:

For example: For 2025, Tillie is 55 and single, her standard deduction is $15,000. If she is age 65 or older her standard deduction is $17,000 ($15,000 + $2,000). If Tillie is also blind, her standard deduction jumps to $19,000 ($15,000 + $2,000 + $2,000).
Itemized deductions are specific personal expenses the IRS allows taxpayers to deduct. They include:
- Medical and dental expenses over 7.5% of AGI
- Taxes paid such as state and local income taxes, sales taxes, real estate taxes, and personal property taxes based on the value of the item
- Mortgage interest paid on two homes, within limits
- Gifts to qualifying charities
- Casualty and theft losses
- Other itemized deductions paid such as gambling losses to the extent of winnings.
Itemized deductions are reported on Schedule A, Itemized Deductions, then carried to Form 1040, U.S. Individual Income Tax Return, Line12. Where the standard deduction is reported directly on Form 1040, Line 12, no other schedule is required.
There are times when taxpayers may be required to use one type of deduction over the other. The most common example of this is when married couples file separately under the married filing separate (MFS) filing status. In these cases, if one spouse itemizes, the standard deduction for the other spouse is $0. Meaning if one spouse itemizes, the other must also itemize. Otherwise, both spouses could use the MFS standard deduction.
Nonresident alien taxpayers who are required to file Form 1040-NR, U.S. Nonresident Alien Income Tax Return, are not eligible to use the standard deduction. Instead, they can use their itemized deductions.
There are pros and cons to taxpayers using either their standard or itemized deductions. The biggest benefit to using the standard deduction is taxpayers do not have to keep track of their itemized deductions unless there are state benefits for doing so. While using itemized deductions generally means a larger deduction causing taxable income to be lower.
The IRS has a tool at its website to help taxpayers determine the amount of their standard deduction. To use this tool taxpayers will need their date of birth, spouse’s date of birth and filing status along with basic income information including amounts and adjust gross income.
The determination to use the standard deduction or itemized deduction for a taxpayer needs to be made on a taxpayer-by-taxpayer basis. What is correct for one taxpayer might not be automatically correct for another taxpayer.
