2025 List of Itemized Deductions Guide – If you’re preparing your 2025 tax return, understanding itemized deductions can help lower your taxable income and potentially increase your refund. This comprehensive guide covers the 2025 list of itemized deductions, key limits, eligibility rules, and changes under recent legislation like the One Big Beautiful Bill (OBBBA). All information is sourced directly from official IRS resources, including the 2025 Instructions for Schedule A (Form 1040) and Publication 17.
Itemized deductions are claimed on Schedule A (Form 1040) and are only beneficial if they exceed your standard deduction. Most taxpayers take the standard deduction, but high medical costs, large charitable gifts, or significant state taxes in high-tax states can make itemizing worthwhile.
What Are Itemized Deductions in 2025?
Itemized deductions allow you to subtract specific qualified expenses from your adjusted gross income (AGI) instead of claiming the flat standard deduction. For tax year 2025, you report them on Schedule A and enter the total on Form 1040, line 12.
You can only itemize if the total exceeds your standard deduction. Otherwise, take the standard deduction for simplicity. Itemizing requires detailed records, receipts, and forms like Form 1098 (mortgage interest) or Form 8283 (non-cash charity).
Important: Certain new 2025 deductions (tips, overtime, car loan interest, and senior deduction) are not itemized—they go on the new Schedule 1-A and are available whether you itemize or not.
2025 Standard Deduction Amounts: When Should You Itemize?
The IRS adjusts the standard deduction annually for inflation. For tax year 2025:
- Single or Married Filing Separately: $15,750
- Married Filing Jointly or Qualifying Surviving Spouse: $31,500
- Head of Household: $23,625
Additional amounts for age 65+ or blind (added to the above):
- Single or Head of Household: +$2,000 per qualifying person
- Married Filing Jointly/Qualifying Surviving Spouse: +$1,600 per qualifying spouse
Rule of thumb: Itemize only if your total qualified expenses > standard deduction. Use IRS Free File or tax software to compare both options automatically.
Key Changes to Itemized Deductions for Tax Year 2025
Major updates from the One Big Beautiful Bill and prior TCJA rules (now largely permanent):
- SALT cap increased to $40,000 ($20,000 if married filing separately), with a phase-out starting at modified AGI over $500,000 ($250,000 MFS) down to a minimum of $10,000 ($5,000 MFS).
- Home mortgage interest debt limit made permanent at $750,000 ($375,000 MFS).
- Miscellaneous itemized deductions subject to the 2% AGI floor remain permanently eliminated (no unreimbursed employee expenses, tax preparation fees, etc.).
- Private mortgage insurance (PMI) deduction not available for 2025.
- New Schedule 1-A deductions (tips up to $25,000, overtime up to $12,500/$25,000 MFJ, car loan interest up to $10,000, senior deduction up to $6,000) available to everyone—not limited to itemizers.
- Charitable contribution rules remain similar for 2025 (changes like a 0.5% AGI floor start in 2026).
These changes make itemizing more attractive for homeowners and residents of high-tax states.

Tips to Maximize Your 2025 Itemized Deductions
- Bunch expenses: Pay medical bills or make charitable gifts in December to exceed the standard deduction in one year.
- Track mileage: 21¢/mile for medical travel; 14¢/mile for charity.
- Donate appreciated stock: Avoid capital gains tax and deduct fair market value.
- Check SALT strategies: Use the increased $40,000 cap if you live in a high-tax state.
- Document everything: The IRS requires substantiation—lost records mean lost deductions.
- Consider new Schedule 1-A deductions: Even if you itemize, claim tips, overtime, car loan interest, or senior deductions separately for extra savings.
