Itemized vs Standard Deduction
Find out which deduction saves you more money
Should I itemize or take the standard deduction in 2025?
You should itemize if your total itemizable expenses exceed the standard deduction for your filing status. For 2025, that's $15,750 (single), $31,500 (married filing jointly), or $23,625 (head of household). About 90% of taxpayers benefit more from the standard deduction.
- 2025 SALT cap: $40,000 (includes state income tax + property tax)
- Medical expenses deductible only if exceeding 7.5% of AGI
- Mortgage interest deductible on loans up to $750,000
- Charitable donations: up to 60% of AGI for cash donations

Since the TCJA doubled the standard deduction, fewer than 10% of households itemize. But if you're in the 10%, the gap is usually large — five figures, sometimes more. The SALT cap, mortgage interest, and charitable bunching are where the real decisions live.
Real-world scenario
California homeowner with $30K SALT, $18K mortgage interest, $5K donations
Bay Area MFJ couple: property tax $10K + CA state income tax $20K = $30K SALT (fully deductible under the 2025 $40,000 cap, since their MAGI is under $500,000), $18K mortgage interest, $5K cash to a 501(c)(3). Total itemized: $53K. Standard deduction MFJ 2025: $31,500. Itemizing gives them $21,500 more in deductions, about $5,160 less federal tax if all of it would have been taxed at 24%.
The part most people miss
Bunching is the move most people miss. If you're close to the standard deduction line, push two years of charitable donations into one calendar year (a donor-advised fund makes this clean), itemize that year, take the standard the next. You don't lose deductions — you just shift timing to clear the bar.
Most taxpayers take the standard deduction. Itemizing only helps when your Schedule A total exceeds it — mortgage interest, property and state taxes, charitable gifts, and medical expenses above the 7.5%-of-AGI floor. This calculator compares the two totals for you.

Frequently Asked Questions
Should I itemize or take the standard deduction?
You should itemize if your total itemizable expenses exceed the standard deduction for your filing status. For 2025, that's $15,750 (single), $31,500 (MFJ), or $23,625 (HOH) under the OBBB Act.
What is the SALT cap for 2025?
The State and Local Tax (SALT) deduction is capped at $40,000 for 2025 under the OBBB Act ($20,000 for Married Filing Separately), and $40,400 ($20,200) for 2026. This includes state income tax, property tax, and local taxes combined. Above $500,000 of modified AGI ($505,000 for 2026) the cap falls by 30% of the excess, never below $10,000. If you're married filing separately, the phase-down starts at $250,000 ($252,500 for 2026) and you get half of the reduced cap: 15 cents less per dollar over the threshold, never below $5,000.
What medical expenses are deductible?
You can deduct unreimbursed medical expenses that exceed 7.5% of your AGI. This includes doctor visits, prescriptions, health insurance premiums, dental care, vision care, and medical equipment.
Are charitable donations fully deductible?
Cash donations to qualified charities are generally deductible up to 60% of your AGI. Non-cash donations and donations to certain organizations may have lower limits.
Can I deduct mortgage interest?
Yes, mortgage interest on your primary and secondary residence is deductible on up to $750,000 of home acquisition debt ($375,000 MFS), or $1,000,000 ($500,000 MFS) for debt taken out before December 16, 2017. If your average balance is over the limit, only the matching share of the interest is deductible.
