Deductions reduce your taxable income. You either take the standard deduction or itemize β whichever is larger.
| Deduction | Notes |
|---|---|
| Mortgage interest | On up to $750,000 of acquisition debt (for loans after 2017) |
| State and local taxes (SALT) | Capped at $10,000 combined ($40,000 for 2025 under recent law changes, phasing for high earners) |
| Charitable donations | Cash gifts up to 60% of AGI; property donations have separate limits |
| Medical expenses | Only the amount exceeding 7.5% of AGI |
Compare with the standard deduction for your filing status.
