Try It: Add Up Your Itemized Deductions for 2025
Enter a year's expenses for a 2025 return (example figures to start). Medical costs count only above 7.5% of AGI, and state and local taxes stop at the 2025 limit of $40,000.

- "Our medical bills were huge, does any of that count?"
- "Keep the donation receipts in case we itemize."
The Breakdown
Worked example. The Okafors file jointly for 2025 with an adjusted gross income of $120,000 (all figures made up).
| Expense | Paid | Counts on Schedule A |
|---|---|---|
| Medical and dental | $6,000 | $0, because 7.5% of $120,000 is $9,000 |
| State income and property taxes | $12,000 | $12,000, under the $40,000 limit |
| Mortgage interest | $14,000 | $14,000 |
| Gifts to charity | $3,000 | $3,000 |
| Itemized total | $29,000 | |
| 2025 standard deduction, joint | $31,500 |
What the result means. The standard deduction is $2,500 larger, so the Okafors take it. A big medical year could change that: at $20,000 of medical costs, $11,000 would count, pushing the total to $40,000, well past $31,500.
What moves the number. A new mortgage, a year of high medical billsMedical debtMoney owed for health care, such as hospital, doctor, lab or ambulance bills; unpaid bills can go to collections and, in some cases, onto credit reports. See more, larger gifts to charity, or a higher property or state income tax bill can tip a household into itemizing.
