Should I itemize my deductions or take the standard deduction? Enter your mortgage interest, state and local taxes, charitable gifts, and medical expenses — we compare your itemized total against the 2025 standard deduction for your filing status and show you exactly how much you could save.
Run a calculation to see the full math, including the SALT cap and the 7.5% medical expense floor.
This mode reuses the figures from the Calculator tab. It tells you exactly how many more dollars of itemized deductions you would need to beat the 2025 standard deduction for your filing status — your itemized total must exceed the standard deduction for itemizing to win.

You can never take both — you choose whichever deduction is larger.
SALT = State & local taxes (property + income/sales), capped at $10,000 combined
Medical = Only the amount above 7.5% of your AGI is deductible
The difference between the two deductions is multiplied by your marginal tax rate to estimate the tax you save by choosing the larger one.
| Filing Status | 2025 Standard Deduction |
|---|---|
| Single | $15,000 |
| Married Filing Jointly | $30,000 |
| Head of Household | $22,500 |
| Married Filing Separately | $15,000 |
Since the Tax Cuts and Jobs Act roughly doubled the standard deduction, the vast majority of filers no longer itemize. Itemizing usually only pays off when you have a large mortgage, live in a high-tax state, give generously to charity, or have unusually high medical bills.
No lookups needed — the correct 2025 standard deduction for Single, MFJ, Head of Household, and MFS filers is applied automatically.
Your property tax plus state income tax is capped at the $10,000 state and local tax limit, just like the IRS does it.
Medical expenses are reduced by the 7.5% of AGI threshold automatically, so you only see the truly deductible amount.

The standard deduction is a flat amount the IRS lets you subtract from your income without keeping any receipts. For the 2025 tax year, the amounts are:
| Filing Status | 2025 Standard Deduction |
|---|---|
| Single | $15,000 |
| Married Filing Jointly | $30,000 |
| Head of Household | $22,500 |
| Married Filing Separately | $15,000 |
About 9 out of 10 taxpayers take the standard deduction because it requires no documentation and is often larger than what they could itemize. Taxpayers who are 65 or older (or blind) qualify for an additional standard deduction on top of these amounts, which this calculator does not include.
If you itemize, you add up your eligible deductions on Schedule A. The main categories are:
The math is simple: add up everything you could itemize, then compare it with the standard deduction for your filing status. The larger number wins, and the difference multiplied by your marginal tax rate is your estimated tax savings.
Itemizing pays off when your total exceeds the standard deduction. That usually happens when you have a large mortgage, high property and state income taxes, big charitable gifts, or significant medical bills. You must keep records and receipts, and fill out Schedule A.
Best for: Homeowners with big mortgages and high local taxes.
Since the standard deduction was roughly doubled in 2018, most filers get a bigger break with zero paperwork. If your itemized total comes in below the standard deduction, taking the standard deduction is the right call — no receipts, no Schedule A, no math.
Best for: Most filers, especially renters and those with modest deductions.
Mortgage interest $12,000 + property tax $6,000 + state income tax $5,000 (SALT capped from $11,000 to $10,000) + charitable $3,000 + medical $8,000 with AGI $100,000 (7.5% floor = $7,500, so only $500 is deductible).
Because $25,500 is less than the $30,000 standard deduction, this couple should take the standard deduction. The $4,500 difference × 24% marginal rate = $1,080 in estimated tax savings.
