Standard Deduction or Itemizing? How to Choose the Bigger Number
Published October 29, 2026
Your deduction lowers the income the IRS taxes. You can take either the standard deduction, a fixed amount set by your filing status, or itemized deductions listed on Schedule A (Form 1040). The rule is simple: pick whichever is larger. The hard part is adding up the itemized side honestly.
What is the standard deduction for tax year 2026?
Under Revenue Procedure 2025-32, the IRS sets the 2026 standard deduction at $16,100 for single filers and married filing separately, $32,200 for married filing jointly, and $24,150 for head of household. Those are the numbers for returns you file in 2027. Your filing status decides which figure applies, so use the one that matches your return.
When does itemizing make sense?
Publication 501, Dependents, Standard Deduction, and Filing Information, says you should itemize if your total itemized deductions are more than your standard deduction. Common items on Schedule A include home mortgage interest (reported to you on Form 1098), state and local taxes (within the limits in the Schedule A instructions), and charitable gifts. Publication 501 also says that if you're married filing separately and your spouse itemizes, you must itemize too.
Can I deduct charity if I don't itemize?
Yes, beginning in 2026. Publication 505, Tax Withholding and Estimated Tax (2026 edition), says you can deduct cash gifts to eligible tax-exempt organizations even if you take the standard deduction. The maximum is $1,000, or $2,000 for married filing jointly, subject to the limits in that publication.
What does a worked example look like?
Illustration only, with made-up round numbers: Priya is single and files in 2026. She pays $7,400 of mortgage interest, $4,200 of state and local taxes, and gives $1,100 in cash to a charity.
Step 1: Add the itemized items: $7,400 + $4,200 + $1,100 = $12,700.
Step 2: Compare $12,700 with the single standard deduction of $16,100. The standard deduction is larger, so Priya would normally take it.
Step 3: Because Priya doesn't itemize, she can also deduct up to $1,000 of her cash gift under the non-itemizer rule in Publication 505. Her total is $16,100 + $1,000 = $17,100, which beats $12,700 by $4,400.
Priya's numbers are an example, not a promise. The same charity gift would count differently if she itemized, which is why the comparison matters.
What is the most common mistake?
Assuming you should itemize because you own a home. Mortgage interest is often smaller than people expect, especially in the early years of a loan or with a smaller balance. Many people also skip the non-itemizer charity deduction that Publication 505 describes, so compare both paths before you decide.
Two special cases are worth knowing. If you're married filing separately and your spouse itemizes, you can't take the standard deduction, so you must itemize too (Publication 501). If someone else can claim you as a dependent, your standard deduction is capped: for 2026 it can't exceed the greater of $1,350 or your earned income plus $450 (Revenue Procedure 2025-32). Taxpayers who are 65 or older, or blind, get an additional amount that Revenue Procedure 2025-32 also lists.
The comparison also changes from year to year. A new mortgage, a large medical bill, or a big donation can tip the scale toward itemizing. A year with less mortgage interest and fewer gifts usually points back to the standard deduction. That's why it's worth running the numbers again every filing season, rather than copying last year's answer.
What should I do next?
Use this four-step check each year:
- Gather Form 1098, property tax bills, state tax paid, and receipts for cash and noncash gifts.
- Total your possible Schedule A items. Leave out anything you can't document.
- Look up the standard deduction for your filing status for the tax year you're filing.
- Choose the larger number, and add the non-itemizer charity deduction only if you take the standard deduction and it applies to you.
Most people only need to do this comparison once a year, but it's worth doing with real paperwork in front of you. A credentialed tax preparer can run both sides with you if your situation is more complicated.
