Spend a Little More Before Year-End โ Or Not?
Medical expenses and charitable donations are two of the most common itemized deductions, but they work very differently. Medical expenses only count once they exceed 7.5% of your adjusted gross income โ until you clear that floor, extra spending gives you zero tax benefit. Once you're past it, though, every additional dollar of qualifying medical spending is deductible. Charitable donations have no floor at all; they're deductible from the first dollar, up to annual limits tied to your income. But neither one helps unless your itemized total beats the standard deduction, so before year-end, it pays to check whether you're actually ahead of that baseline.
How It's Calculated
| Item | Calculation |
|---|---|
| Medical threshold | AGI ร 7.5% |
| Deductible medical | (medical spending โ threshold), floor $0 |
| Itemized total | deductible medical + charitable donations |
| Verdict | itemized total vs. standard deduction (~$15,000) |
This tool leaves out other common itemized items like state and local taxes (capped at $10,000) and mortgage interest, so your real itemized total may be higher than what's shown here. It also doesn't reflect your marginal tax bracket, which determines how much a given deduction is actually worth in dollars saved. Use this as a quick year-end gut check โ if you're near the medical threshold or the standard deduction line, review your full return with a tax professional or software before December 31.
