Claim Standard Deduction Married Jointly – Married couples filing jointly can significantly lower their taxable income by claiming the standard deduction. This straightforward IRS benefit often saves time and money compared to itemizing deductions. As of the 2026 tax filing season for 2025 income, the standard deduction for married filing jointly remains one of the most popular choices for U.S. taxpayers. This guide explains everything you need to know about claiming it correctly, with the latest IRS figures and step-by-step instructions.
What Is the Standard Deduction When Filing Married Jointly?
The standard deduction is a fixed dollar amount set by the IRS that reduces your adjusted gross income (AGI) before calculating your federal tax bill. When you file as married filing jointly (MFJ), you and your spouse combine your incomes and deductions on one return, qualifying for the highest base standard deduction amount among common filing statuses.
Unlike itemized deductions (which require tracking receipts for mortgage interest, medical expenses, charitable contributions, etc.), the standard deduction requires no documentation. Most married couples automatically qualify unless they choose to itemize on Schedule A (Form 1040).
2025 Standard Deduction Amounts for Married Filing Jointly
For tax year 2025 (returns filed in 2026), the basic standard deduction for married filing jointly is $31,500. This amount reflects inflation adjustments plus an increase from the One Big Beautiful Bill (OBBB) Act.
Here’s a quick comparison of 2025 standard deduction amounts:
- Married filing jointly or qualifying surviving spouse: $31,500
- Single or married filing separately: $15,750
- Head of household: $23,625
These figures apply if neither spouse is age 65 or older and neither is blind.
Additional Standard Deduction for Age 65+ or Blindness (Married Filing Jointly)
If you or your spouse qualify, you can add extra amounts to the base deduction:
- One spouse age 65 or older (or blind): Add $1,600 → Total $33,100
- Both spouses age 65 or older (or one 65+ and one blind, or both blind): Add $3,200 → Total $34,700
Age is determined as of December 31, 2025 (born before January 2, 1961). Blindness requires meeting the IRS definition (e.g., vision no better than 20/200 or field of vision 20 degrees or less). You indicate eligibility by checking boxes on Form 1040 or 1040-SR.
New Enhanced Deduction for Seniors (2025–2028)
Thanks to the OBBB Act, individuals age 65 or older can claim an additional $6,000 deduction per qualifying person ($12,000 if both spouses qualify). This is separate from the regular age/blindness addition and works whether you take the standard deduction or itemize. It phases out for modified AGI over $150,000 (married filing jointly). Claim it on the new Schedule 1-A (Form 1040).
How to Claim the Standard Deduction Married Filing Jointly (Step-by-Step)?
Claiming the standard deduction is simple and automatic for most couples:
- Choose your filing status — Select “Married filing jointly” at the top of Form 1040 or 1040-SR.
- Calculate your total standard deduction — Start with the $31,500 base and add any age/blindness amounts using the IRS tables in Publication 17 or Form 1040 instructions.
- Enter it on your return — On Form 1040, report the total on line 12 (do not complete Schedule A for itemized deductions).
- Check the appropriate boxes — On the front of Form 1040, mark boxes for age 65+ and/or blindness for you and/or your spouse.
- File electronically or by mail — Tax software like TurboTax, H&R Block, or IRS Free File automatically calculates and applies the correct amount. Paper filers use the instructions for Form 1040.
No extra forms are needed unless claiming the enhanced senior deduction (Schedule 1-A).
Should You Claim the Standard Deduction or Itemize? (Married Filing Jointly)
Most married couples benefit from the standard deduction because it’s higher than many people’s itemized total. Use it if your combined qualified expenses (mortgage interest, state/local taxes up to the SALT cap, medical expenses over 7.5% of AGI, charity, etc.) are less than $31,500 (or your adjusted total with age additions).
Tip: Run both scenarios in tax software. If itemizing saves more, attach Schedule A and enter that total on Form 1040 instead.
Important rule for married couples: If one spouse itemizes, the other spouse cannot take the standard deduction—you must both itemize or both take the standard deduction.
Special Rules and Limitations for Married Filing Jointly
- Dependents: If either spouse can be claimed as a dependent on someone else’s return, the standard deduction is limited (greater of $1,350 or earned income + $450, not exceeding the regular amount).
- Married filing separately: You generally cannot take the standard deduction if your spouse itemizes.
- Nonresident aliens: Limited eligibility (exceptions apply for certain spouses of U.S. citizens/residents).
- Short tax year: Prorated or unavailable in some cases.
Always verify eligibility in IRS Publication 501 or Publication 17.

For tax year 2026 (returns filed in 2027), the basic standard deduction for married filing jointly rises to $32,200 due to inflation adjustments. Additional amounts for age/blindness will also increase slightly. Plan ahead by tracking expenses now.
Common Mistakes to Avoid
- Forgetting to check age/blindness boxes (losing $1,600+ per person).
- Claiming the standard deduction when itemizing would save more.
- Filing separately when one spouse itemizes.
- Missing the new enhanced senior deduction on Schedule 1-A.
Double-check your return or use professional tax software to catch these errors.
