Standard Deduction vs Itemizing: 2026
Every filer faces the same fork: take the standard deduction or itemize on Schedule A. For 2026 the fork moved — the One Big Beautiful Bill Act raised the SALT cap to $40,400, making itemizing the winner for many high-tax-state homeowners for the first time since 2017. Enter your numbers and this calculator runs both paths: your effective SALT under the cap, mortgage interest, charity, and medical expenses above 7.5% of income — and names the winner.
What the comparison shows
A married couple filing jointly with $18,000 of property tax and $14,000 of state income tax, $9,000 of mortgage interest, $2,500 of charitable gifts, and $5,000 of medical expenses on $160,000 of AGI — their SALT totals $32,000, safely under the 2026 $40,400 cap. Medical expenses clear nothing: 7.5% of $160,000 is $12,000, above the $5,000 spent. Itemized deductions total $43,500 vs the joint standard deduction of $32,200 — itemizing wins by $11,300, worth about $2,486 of federal tax at a 22% marginal rate. Change the numbers and the winner flips fast: this is a math problem, not a loyalty question.
Output · formula · meaning
| Output | Formula | What it means |
|---|---|---|
| Effective SALT deduction | min(property + income tax, $40,400) | Your SALT after the 2026 cap: $32,000 here — the full $32,000 fits. |
| Deductible medical expenses | max(0, medical − 7.5% × AGI) | The floor eats most medical spending: $0 deductible here. |
| Itemized total | SALT + mortgage interest + charity + deductible medical | Your Schedule A line: $43,500. |
| Standard deduction | 2026 IRS amount for your status | The no-receipts option: $32,200 for joint filers. |
| Estimated tax savings | (itemized − standard) × marginal rate | What the win is worth in federal tax: $2,486 here. |
Who uses this
- Homeowners in high-tax states: the $40,400 SALT cap is the reason itemizing is back on the table — run your property tax before assuming the standard deduction wins.
- Big charitable givers: bunching two years of donations into one can push itemizing over the line — test the bunching year here.
- Anyone with a rough medical year: only spending above 7.5% of income counts — the calculator applies the floor for you.
- Tax planners: the margin tells you how close the race is — within a few hundred dollars, plan December moves to tip it.
Accuracy & limitations
Amounts are the 2026 tax year figures: standard deductions of $16,100 (single/MFS), $24,150 (head of household), $32,200 (joint), and the One Big Beautiful Bill Act SALT cap of $40,400 ($20,200 for married filing separately), which phases down above $505,000 of modified AGI. This is a deduction comparison, not a tax return: it doesn’t model AMT, the 65+/blind additional amounts, state taxes, or the many itemized categories beyond these five. A deduction saves you at your marginal rate only — that’s why the rate field matters. Itemizing requires receipts and Schedule A; the standard deduction requires neither.

What is the 2026 standard deduction?
For tax year 2026: $16,100 for single and married-filing-separately filers, $24,150 for head of household, and $32,200 for married filing jointly. Additional amounts apply for filers 65+ or blind. These are the IRS inflation-adjusted 2026 figures.
What is the SALT cap for 2026?
The One Big Beautiful Bill Act raised the state-and-local-tax deduction cap to $40,400 for 2026 ($20,200 for married filing separately) — up from $10,000. It phases down above $505,000 of modified AGI (floor $10,000). Only filers who itemize on Schedule A can claim it; it changes nothing for standard-deduction filers.
Should I itemize or take the standard deduction?
Itemize if your Schedule A total — SALT (capped), mortgage interest, charitable gifts, and medical expenses above 7.5% of income — exceeds your standard deduction. Otherwise the standard deduction wins. Most filers take the standard deduction; high-tax-state homeowners itemize most often. The calculator above does the exact comparison.
Does the 7.5% medical floor really erase most medical spending?
Usually, yes. Only the part of medical and dental expenses above 7.5% of AGI is deductible: on $160,000 of income the floor is $12,000, so $5,000 of medical spending deducts nothing. Bunching elective procedures into one year can clear the floor — that’s the planning move the calculator helps you test.
Can I switch between itemizing and the standard deduction year to year?
Yes — you choose fresh each year. That’s what makes bunching work: load charitable gifts and elective medical costs into one year so itemizing wins big, then take the standard deduction the next year. Run both years through the calculator to see the two-year payoff.
