For tax year 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly. That means a married couple with no other moves can already shield $32,200 of income from federal tax before doing a single calculation. The big question every spring is the same: will itemizing beat that flat number, or are you just creating extra paperwork for the same outcome?
The answer changed meaningfully in 2026. The One Big Beautiful Bill Act raised the SALT (state and local tax) deduction cap from $10,000 to $40,400, opening itemizing back up for high-tax-state homeowners who had been locked into the standard deduction since 2018. That single change is enough to flip the math for a lot of households. This guide walks through the 2026 numbers, the rules that often trip people up, and two worked examples so you can see the comparison play out in dollars rather than abstract advice.
What's Actually at Stake in 2026
Every taxpayer gets to subtract one of two amounts from their adjusted gross income (AGI) before federal income tax is calculated:
- The standard deduction — a flat dollar amount based on your filing status. No receipts. No itemized list. You just claim it.
- The total of your itemized deductions — specific expenses listed on Schedule A: state and local taxes, mortgage interest, charitable gifts, and a few other narrow categories.
You pick whichever is bigger. That's the whole game. The catch is that "bigger" depends on five or six moving parts, and most of those parts changed in 2026. To see how a deduction affects your bracket, run the numbers in our Tax Bracket Calculator.
2026 Standard Deduction Amounts
The IRS publishes the official figures each fall. For tax year 2026, the standard deduction by filing status is:
| Filing Status | 2026 Standard Deduction |
|---|---|
| Single | $16,100 |
| Married Filing Jointly & Qualifying Surviving Spouse | $32,200 |
| Head of Household | $24,150 |
| Married Filing Separately | $16,100 |

Extra Amounts for Age 65+ and Blindness
If you are 65 or older, or blind, the IRS adds an additional standard deduction on top of the base amount. For 2026, that add-on is $2,050 for single and head-of-household filers, and $1,650 per qualifying spouse for married filers. A 67-year-old single retiree therefore gets $16,100 + $2,050 = $18,150. A married couple where both spouses are 67 and one is blind would add $1,650 three times to the $32,200 base.
Dependents Get a Reduced Amount
If someone else can claim you as a dependent (e.g., a college student claimed by a parent), your standard deduction is limited to the greater of $1,350 or your earned income plus $450, capped at the regular single amount. This is why a dependent's first job often produces a refund of all withheld federal tax.
What Counts as an Itemized Deduction in 2026
Itemized deductions are reported on Schedule A. The major categories — and the rules that limit each one in 2026 — are:
State and Local Taxes (SALT) — capped at $40,400
You can deduct state and local income taxes (or, by election each year, sales taxes) plus property taxes on real estate you own. Starting in 2026, the combined SALT cap is $40,400, up from $10,000 in 2025. The cap rises 1% per year through 2029, then reverts to $10,000 in 2030 unless extended.
The expanded cap phases out for higher earners: it starts shrinking once modified adjusted gross income (MAGI) exceeds $500,000 ($250,000 if married filing separately), at a rate of 30 cents per dollar of income above the threshold, but it never drops below the old $10,000 floor.
Home Mortgage Interest — capped at $750,000 of debt
Interest is deductible on home acquisition debt up to $750,000 ($375,000 if married filing separately) for mortgages taken out after December 15, 2017. Loans originated on or before that date are grandfathered to the older $1,000,000 cap. The 2026 law made the $750,000 limit permanent. Interest on a HELOC or home equity loan is deductible only if the proceeds were used to buy, build, or substantially improve the home that secures the loan.
Charitable Contributions — new 0.5% AGI floor
Beginning in 2026, itemizers can deduct charitable contributions only to the extent they exceed 0.5% of AGI. If your AGI is $200,000, the first $1,000 of giving doesn't count toward your itemized total. Large gifts still produce a real deduction, but small annual giving is now partially absorbed by the floor.
Medical and Dental Expenses — over 7.5% of AGI
Out-of-pocket medical expenses are deductible only to the extent they exceed 7.5% of AGI. Most households never clear this hurdle, but a major surgery, long-term care year, or birth with complications can push someone over it.
Casualty and Theft Losses — only in federally declared disaster areas
Personal casualty losses are deductible only when attributable to a federally declared disaster. Routine theft or property damage outside a declared disaster does not qualify.
Worked Example #1: Single Renter in a Moderate-Tax State
Sarah is a 32-year-old single filer earning $85,000 of taxable wages. She rents, owes $4,200 of state income tax, donates $1,500 to her local food bank, and has $600 in routine medical bills.
| Item | Amount | Counts? |
|---|---|---|
| State income tax | $4,200 | Yes (under SALT cap) |
| Property tax | $0 | n/a (rents) |
| Mortgage interest | $0 | n/a (rents) |
| Charitable gifts | $1,500 | Reduced by 0.5% of AGI floor: $1,500 − $425 = $1,075 |
| Medical (over 7.5% AGI) | $0 | Below floor |
| Itemized total | $5,275 | |
| Standard deduction | $16,100 |
Sarah takes the standard deduction. Itemizing leaves $10,825 on the table. This is the typical outcome for renters and most non-homeowners — without property tax and mortgage interest, it's hard to clear $16,100.

Worked Example #2: Married Homeowners in a High-Tax State
Jay and Priya file jointly and have an AGI of $220,000. They own a home in New Jersey with a $620,000 mortgage at 6.5%, paying about $40,000 of mortgage interest in 2026. Their state income tax is $14,500, property tax is $13,000, and they donate $6,000 to their place of worship.
| Item | Raw Amount | Deductible Amount |
|---|---|---|
| State income tax | $14,500 | $27,500 combined — under the $40,400 SALT cap |
| Property tax | $13,000 | |
| Mortgage interest (debt under $750k) | $40,000 | $40,000 |
| Charitable gifts ($6,000 minus 0.5% × $220,000 = $1,100) | $6,000 | $4,900 |
| Itemized total | $72,400 | |
| Standard deduction | $32,200 |
Jay and Priya itemize. The extra $40,200 of deduction at a 24% federal marginal bracket is roughly $9,648 of tax savings versus taking the standard deduction. Note that their entire SALT bill of $27,500 was deductible under the new cap; in 2025 only $10,000 of it would have counted, and itemizing might not have beaten the standard deduction at all. This is the household profile most affected by the 2026 SALT change.
A Quick Decision Framework
You probably want to itemize if your situation includes most of these:
- You own a home and your mortgage interest plus property tax exceeds about $20,000.
- You live in a high-tax state (CA, NY, NJ, IL, MA, OR, MN, HI, CT) and your combined state income + property tax is well above $10,000.
- You give more than 1–2% of AGI to charity in cash each year.
- You had a major medical event that pushed out-of-pocket costs past 7.5% of AGI.
You probably want the standard deduction if:
- You rent.
- You own but the mortgage is small or paid off and your state taxes are modest.
- Your charitable giving is occasional rather than systematic.
- Your filing status is married filing jointly — the $32,200 hurdle is high.
If you're close to the line, run both columns. Tax software does this automatically, but a quick spreadsheet beats guessing. To see how each choice flows through to your actual tax bill, pair this comparison with our guide to 2026 tax brackets.
Above-the-Line Moves That Help Either Way
Whether you itemize or not, certain "above-the-line" deductions reduce your AGI directly — you don't have to choose. They include traditional IRA contributions, HSA contributions, the deductible portion of self-employment tax, student loan interest (up to $2,500), and pre-tax 401(k) contributions (technically excluded from wages, with the same effect). Read more about HSAs and self-employment tax in our quarterly estimated taxes guide.
New for 2026: non-itemizers can claim a small above-the-line charitable deduction — up to $1,000 single / $2,000 married filing jointly — for cash gifts to qualifying public charities. Donor-advised funds and private foundations don't qualify, and the deduction doesn't apply to property or appreciated stock. It's a modest sweetener, but a welcome return of a benefit that lapsed after 2021.
Common Mistakes That Cost You Money
A few patterns we see every spring:
- Forgetting the SALT cap is per return, not per spouse. A married-filing-jointly couple shares one $40,400 cap. Married filing separately shares it as $20,200 each.
- Counting federal income tax in SALT. Federal taxes are not deductible. Only state and local income or sales taxes plus property taxes go on Schedule A.
- Deducting HELOC interest used for non-home expenses. A HELOC used to consolidate credit card debt or pay tuition is no longer deductible. Only proceeds used to buy, build, or substantially improve the home count.
- Bunching gone wrong. "Bunching" two years of charitable giving into one year is still a smart strategy in 2026, but the new 0.5% AGI floor reduces the benefit slightly. Run the math.
- Skipping itemizing in a high-medical year. A year with major surgery, fertility treatment, or long-term care often pushes medical past the 7.5% AGI floor for the first and only time — check before you default to the standard amount.
Frequently Asked Questions
Can I switch between standard and itemized from year to year?
Yes. The choice is annual. Many homeowners now use a "bunching" strategy: itemize every other year by concentrating two years of charitable gifts and elective property tax payments into one calendar year, then take the standard deduction in the off year.
Does the 2026 standard deduction increase apply to my 2025 return?
No. The $16,100 / $32,200 amounts apply to tax year 2026 (the return you file by April 15, 2027). For your 2025 return filed in spring 2026, the older 2025 amounts apply.
I'm self-employed — do business expenses go on Schedule A?
No. Self-employment business expenses are deducted on Schedule C (or the relevant business form) regardless of whether you itemize personal deductions. You can take the standard deduction and still deduct every legitimate business expense.
What happens if married couples each itemize on separate returns?
If one spouse itemizes on a married-filing-separately return, the other spouse must also itemize — even if their itemized total is $0. This is a common surprise that turns into a worse outcome than filing jointly.
Is the SALT cap going away?
Under current law, the expanded cap rises 1% annually through 2029 and then reverts to $10,000 in 2030. Whether Congress extends or modifies it again is a political question, not a settled one.
Does the $40,400 SALT cap apply to all filers?
No. It phases down for households with MAGI above $500,000 ($250,000 for married filing separately), shrinking by 30 cents per dollar of income above the threshold but never dropping below $10,000.
Can I deduct charitable giving without itemizing?
Yes — in 2026 only, up to $1,000 single / $2,000 married filing jointly for cash gifts to qualifying public charities. The deduction reduces your AGI directly and doesn't require Schedule A.
