What Qualifies as Itemized Deductions Guide – Itemized deductions allow eligible US taxpayers to subtract specific qualified expenses from their adjusted gross income (AGI) on Schedule A (Form 1040). This reduces taxable income and potentially lowers your federal tax bill. Unlike the standard deduction (a fixed amount based on filing status), itemized deductions require tracking and documenting actual expenses such as medical costs, certain taxes, mortgage interest, and charitable gifts.
You claim itemized deductions only if their total exceeds your standard deduction. Most taxpayers take the standard deduction for simplicity, but high-expense situations (e.g., large medical bills, homeownership, or significant charitable giving) often make itemizing more beneficial.
Standard Deduction vs. Itemized Deductions: When to Itemize
The IRS lets you choose the larger of the standard deduction or itemized deductions each year. Itemizing makes sense if your qualified expenses surpass the standard deduction amounts.
For tax year 2025 (returns filed in 2026):
- Single or Married Filing Separately: $15,750
- Married Filing Jointly or Qualifying Surviving Spouse: $31,500
- Head of Household: $23,625
Amounts increase slightly for 2026 and include extra amounts for those age 65+ or blind.
Pro tip: Use tax software or IRS tools to compare both options. New 2025 above-the-line deductions (e.g., qualified tips up to $25,000, overtime pay, car loan interest up to $10,000, and enhanced senior deduction) are claimed on Schedule 1-A and available regardless of whether you itemize or take the standard deduction.
2025-2026 Standard Deduction Amounts at a Glance
| Filing Status | 2025 Amount | 2026 Amount |
|---|---|---|
| Single / Married Filing Separately | $15,750 | $16,100 |
| Married Filing Jointly / Qualifying Surviving Spouse | $31,500 | $32,200 |
| Head of Household | $23,625 | $24,150 |
These figures are inflation-adjusted under the One Big Beautiful Bill (OBBBA) and prior law. Additional amounts apply for age 65+ or blindness.
What Qualifies as Itemized Deductions on Schedule A?
Here are the main categories that qualify for tax year 2025, per official IRS Schedule A instructions and related publications.
Medical and Dental Expenses
You can deduct unreimbursed medical and dental expenses that exceed 7.5% of your AGI. This includes:
- Doctor, dentist, and qualified practitioner fees
- Prescription medicines and insulin
- Hospital and nursing care
- Long-term care services (with age-based premium limits)
- Health insurance premiums (not pre-tax or employer-paid)
- Eyeglasses, hearing aids, crutches, wheelchairs, and home modifications for medical needs
- Transportation for medical care (21 cents per mile in 2025, plus parking/tolls)
- Certain treatments like acupuncture, stop-smoking programs (if prescribed), and fertility treatments
Key exclusions: Cosmetic procedures (unless reconstructive), non-prescription drugs (except insulin), general health items like vitamins or gym memberships, and reimbursed expenses.
Keep detailed records—only the amount over 7.5% of AGI qualifies.
State and Local Taxes (SALT)
Deduct state and local income taxes or general sales taxes (not both), plus real estate and personal property taxes. For 2025, the total SALT deduction is capped at $40,000 ($20,000 if married filing separately). The cap phases down (but not below $10,000) if your modified AGI exceeds $500,000 ($250,000 if MFS).
Real estate taxes must be based on the property’s value and levied for public welfare. Personal property taxes (e.g., car registration) must be value-based.
Home Mortgage Interest and Investment Interest
- Home mortgage interest: Interest on loans used to buy, build, or substantially improve your main or second home. Debt limits: up to $750,000 ($375,000 if MFS) for loans after Dec. 15, 2017; $1 million ($500,000 if MFS) for earlier loans.
- Report via Form 1098 or directly if not reported. Points may be deductible.
- Investment interest: Interest on money borrowed to invest (attach Form 4952).
Personal interest (e.g., credit cards) does not qualify.
Gifts to Charity
Cash or property donations to qualified 501(c)(3) organizations, churches, or governments. Deduct:
- Cash/check donations (keep records for $250+)
- Fair market value of property (Form 8283 required for non-cash over $500)
Limits apply (e.g., 60% of AGI for cash to public charities). Carryovers from prior years are allowed. Starting in tax year 2026, a 0.5% of AGI floor applies to charitable deductions for itemizers.
Casualty and Theft Losses
Only losses from federally declared disasters (attach Form 4684). Personal losses must exceed $100 per event and 10% of AGI overall. Income-producing property losses have different rules.
Other Itemized Deductions
Limited categories include:
- Gambling losses (up to winnings)
- Federal estate tax on income in respect of a decedent
- Certain foreign income taxes (or claim a credit instead)
- Amortizable bond premiums
Unreimbursed employee expenses and most miscellaneous deductions remain suspended.
Key Limits and Rules for 2025 Itemized Deductions
- No overall limit on itemized deductions for most taxpayers (the Pease limitation was eliminated and made permanent under recent law, though a 35% benefit cap applies to the top 37% bracket in some cases).
- High-income phaseouts apply to SALT.
- All expenses must be paid during the tax year and not reimbursed.
- Married filing separately has special rules—spouses generally must both itemize or both take standard.
Important Changes for 2025-2026
- SALT cap increased to $40,000 (from $10,000) for 2025 under the One Big Beautiful Bill.
- New above-the-line deductions (tips, overtime, car loans, seniors) do not go on Schedule A.
- For 2026: Charitable contributions face a new 0.5% AGI floor; top-bracket taxpayers see a reduced benefit on itemized deductions.
Always check IRS.gov for late-breaking updates.
How to Claim Itemized Deductions?
- Gather records (receipts, Form 1098 for mortgage, charity acknowledgments, medical bills).
- Complete Schedule A (Form 1040) and attach to your return.
- Compare total (line 17) to your standard deduction—enter the larger on Form 1040.
- E-file or mail by the deadline (usually April 15, or October 15 with extension).
Tips to Maximize Your Itemized Deductions
- Bunch charitable donations into one year.
- Prepay qualified state taxes (if allowed) before year-end.
- Track medical expenses aggressively if you’re close to the 7.5% floor.
- Use the IRS sales tax deduction calculator if it beats actual income taxes paid.
- Consult a tax professional or use reputable software—rules are complex and errors can trigger audits.
Frequently Asked Questions About Itemized Deductions
Do I need to itemize to deduct medical expenses?
Yes—medical expenses are only deductible on Schedule A (above the 7.5% floor).
Can I deduct my property taxes if I take the standard deduction?
No—property taxes are part of SALT and require itemizing.
What if my itemized deductions are lower than the standard deduction?
You can still elect to itemize (check the box on Schedule A), but it’s rarely beneficial unless required for state taxes or other reasons.
Are there any new deductions in 2025 that replace itemizing?
No—the new tip/overtime/car loan/senior deductions are available to everyone via Schedule 1-A.
