Itemized Deductions Calculator 2026: Should You Itemize or Take the Standard Deduction?

Should you itemize your deductions in 2026, or take the standard deduction? This itemized deductions calculator tells you in about a minute.

Standard deduction vs itemized: how the choice works

Every taxpayer can subtract a flat amount from their income, called the standard deduction. You can also add up certain real expenses, like state taxes, mortgage interest and gifts to charity, and subtract that total. That second option is called itemizing. You get one or the other, so you want whichever number is bigger.

Type your numbers into the calculator below. It adds up your itemized deductions the way the IRS form for itemized deductions (Schedule A) does, with the 2026 rules built in. Then it shows which choice lowers your tax more. It works as a standard deduction vs itemized calculator and a SALT deduction calculator at the same time.

All of the numbers in it come from the IRS. For 2026 the standard deduction is $16,100 if you’re single, $32,200 for a married couple filing together, and $24,150 for a head of household. Your deduction for state and local taxes, often called SALT, can go up to $40,400 for 2026. That SALT limit gets smaller once household income passes $505,000.

Two charity rules are also new this year. If you itemize, the first sliver of your giving (0.5% of your income) no longer counts. On the other hand, if you take the standard deduction, you can now deduct up to $1,000 of cash gifts on top of it ($2,000 for married couples). The calculator handles both for you.

Itemized deductions calculator for 2026

Fill in what you know and leave the rest at zero. When you press the button, you’ll see your itemized total line by line, your standard deduction, and roughly how much tax the better choice saves you.

How to use this itemized deduction calculator

First, pick your filing status and enter your income. The calculator asks for your adjusted gross income, or AGI. That’s your total income minus a few adjustments, and you can find it on line 11 of your Form 1040. Last year’s number is a fine estimate, since for most people it doesn’t change much.

Next, count everyone on your return who will be 65 or older by December 31, 2026, or who is legally blind. Each one raises your standard deduction, so this box often changes the answer for retirees.

Then enter the four big itemized deductions:

• State and local taxes (SALT): the state income tax taken out of your paychecks, plus your property tax bill.
• Mortgage interest: box 1 of the Form 1098 your lender mails in January. For 2026, your monthly statements will get you close.
• Medical bills: only the part above 7.5% of your AGI counts. Unless you had a big medical year, leave this at zero.
• Gifts to charity: enter cash gifts and donated items as two separate numbers, because the 2026 rules treat them differently.

Finally, press the button, and the itemized deduction calculator shows both totals side by side. If they are close, read the note under the result. In a close year, a small change in timing can flip the answer.

The 2026 standard deduction, straight from the IRS

The IRS published the 2026 amounts in its yearly inflation update, Revenue Procedure 2025-32, on October 9, 2025. These are the numbers this itemized deductions calculator uses.

Filing status	2026 standard deduction	Extra for each person 65 or older or blind
Single	$16,100	$2,050
Married filing jointly	$32,200	$1,650
Married filing separately	$16,100	$1,650
Head of household	$24,150	$2,050

If you’re 65 or older, or blind, you also get the extra amount in the last column. Married filers get $1,650 per person, and single filers and heads of household get $2,050 (section 3.14 of the same IRS update). So a married couple who are both 65 start with $32,200 plus $3,300, or $35,500. Their itemized deductions have to beat that number before itemizing helps at all. That’s why many retired couples take the standard deduction unless they have a big year of giving.

There’s also a new $6,000 deduction for people 65 and older (IRS summary, Section 70103). It shrinks at higher incomes, but you get it whether you itemize or take the standard deduction. Because it doesn’t change which choice is better, the calculator leaves it out.

What counts as an itemized deduction in 2026

Schedule A, the IRS form for itemized deductions, has six sections. Most households only ever use four of them. Below is what goes in each one and its 2026 limit, based on the Instructions for Schedule A and the 2026 updates the IRS has released so far.

State and local taxes (SALT)

This is your property tax, plus either your state and local income tax or your state sales tax. You pick whichever of those two is bigger, because you can only take one. For 2026 the SALT total you can deduct is capped at $40,400, or $20,200 if you’re married filing separately (IRS correction to the 2026 Form 1040-ES).

Through 2024 the SALT cap was only $10,000. So if your taxes never got you past the standard deduction before, run the numbers again. With the higher cap, more people may come out ahead with itemized deductions in 2026, and the SALT deduction calculator above applies it for you.

Home mortgage interest

This is the interest on a loan you used to buy, build or improve your main home, plus one second home. For loans taken out after December 15, 2017, interest only counts on the first $750,000 you borrowed (Schedule A instructions). However, older loans have a $1 million limit. Each January, your lender also reports the interest to you on Form 1098.

Medical and dental expenses

These are costs you paid yourself that insurance didn’t cover. Only the part above 7.5% of your AGI counts. For example, with $90,000 of income, the first $6,750 of medical bills doesn’t help you at all. As a result, many families never get past that line. The ones who do usually had a hospital stay, long-term care or a lot of dental work that year.

Gifts to charity

This is the cash you gave, plus the fair market value of the things you donated, meaning what they would sell for used. New for 2026, only the part of your giving above 0.5% of your AGI counts when you itemize. With $100,000 of income, for example, your first $500 of gifts drops out. If your donated items total more than $500 for the year, you also file Form 8283. Very large gifts have extra limits, which our guide to noncash charitable contribution limits covers.

The other two sections

Investment interest and losses from a federally declared disaster have their own forms and rarely come up. In addition, gambling losses go on the last line, and they can’t be more than your winnings. The itemized deduction calculator skips these because few people have them. If you do, your tax software will handle them.

SALT deduction calculator: how the 2026 cap and phase-down work

For most people the SALT math is simple. Add your state income tax (or sales tax) to your property tax. If the total is $40,400 or less, you deduct all of it. If it’s more, you deduct $40,400 and the rest doesn’t count. That’s all a SALT tax calculator needs to do when income is under $505,000.

Above $505,000 of income, the cap starts to shrink. The IRS calls this a phase-down, and the Schedule A instructions spell out the steps:

1. Take your income above $505,000.
2. Multiply that amount by 30%.
3. Subtract the result from $40,400.
4. If the answer is below $10,000, your cap is $10,000. It never goes lower.

For married couples filing separately, every number is half: the shrinking starts at $252,500, and the lowest cap is $5,000 (IRS 2026 figures). Strictly speaking, the IRS uses modified adjusted gross income (MAGI) here. For almost everyone that’s the same as AGI, so the calculator uses your AGI.

Your 2026 income (single, joint or head of household)	Your SALT cap
$505,000 or less	$40,400
$530,000	$32,900
$550,000	$26,900
$580,000	$17,900
$606,334 or more	$10,000

To see how the $550,000 row works, start with the income above $505,000, which is $45,000. Next, thirty percent of $45,000 is $13,500. Then $40,400 minus $13,500 leaves a cap of $26,900. So a couple at that income who paid $45,000 in state and property taxes can deduct $26,900, and the other $18,100 doesn’t count.

The two 2026 charity rules that change the answer

If you give to charity, 2026 changes the math in two ways, and they push in opposite directions.

First, itemizers lose a small slice. Under the new rule in Section 170(b)(1)(I) of the tax code, gifts to charity only count above 0.5% of your income. The law measures this against your “contribution base,” which for nearly everyone is just AGI. At $80,000 of income, your first $400 of giving doesn’t count. At $200,000, it’s the first $1,000. The calculator takes this off your gifts before adding them to your itemized total.

Second, people who take the standard deduction gain something. Starting in 2026, you can deduct up to $1,000 of cash gifts ($2,000 on a joint return) on top of the standard deduction (IRS summary of Section 70424). It covers cash only, so donated clothes, furniture and household goods don’t qualify. In addition, gifts to donor-advised funds don’t qualify. The calculator adds this to your standard deduction, since that’s the real number you’re comparing against.

Together, these two rules raise the bar for itemizing. A single filer who gave at least $1,000 in cash needs more than $17,100 of itemized deductions to come out ahead, even though the standard deduction is $16,100. Our itemized deductions calculator includes that extra $1,000 automatically.

Three 2026 households, worked out

Here’s what the itemized deductions calculator shows for three common situations. Every number is shown, so you can check the math against your own.

A renter in a state with no income tax

This renter is single, earns $70,000 and has no mortgage. They paid about $1,100 in sales tax, gave $600 in cash and donated $900 worth of clothes and kitchen items.

• Itemized total: $1,100 of sales tax, plus $1,150 of gifts ($1,500 given, minus the first $350, which is 0.5% of their income), comes to $2,250.
• Standard deduction: $16,100, plus the $600 cash-gift deduction, comes to $16,700.

The standard deduction beats their itemized total by $14,450, and it isn’t close. So this renter takes the standard deduction, still deducts the $600 cash gift, and keeps tracking donated items in case a future year looks different.

A homeowner couple in a high-tax state

This couple is married, files jointly and earns $160,000. They paid $9,500 in state income tax, $8,200 in property tax and $14,000 in mortgage interest. They also gave $2,400 in cash and donated $1,800 worth of items.

• State and local taxes (SALT): $9,500 plus $8,200 is $17,700. That’s under the cap, so all of it counts.
• Mortgage interest: $14,000.
• Gifts: $4,200 given, minus the first $800 (0.5% of their income), leaves $3,400.
• Itemized total: $35,100.
• Standard deduction: $32,200, plus the $2,000 cash-gift deduction, comes to $34,200.

Itemized deductions win by $900. In the 22% tax bracket, that’s about $198 less tax. It’s close enough that one forgotten bag of donated clothes matters. Careful tracking of their donated items is what put this couple over the line.

A retired couple who give a lot

This couple is married, files jointly, and both are 68. Their house is paid off, and they earn $95,000. In 2026 they paid $6,000 in property tax and $2,800 in state income tax and had $4,000 of medical bills. They also gave $6,000 in cash and donated $2,500 worth of items.

• State and local taxes (SALT): $8,800.
• Medical: $0, because only bills above $7,125 (7.5% of their income) count.
• Gifts: $8,500 given, minus the first $475, leaves $8,025.
• Itemized total: $16,825.
• Standard deduction: $32,200, plus $3,300 for their ages, plus the $2,000 cash-gift deduction, comes to $37,500.

The standard deduction beats their itemized total by more than $20,000. For this couple, the smart move is the standard deduction every year, plus the $2,000 cash-gift deduction. Itemizing would only pay off if they packed two or three years of a very large gift into a single year.

What this itemized tax deduction calculator leaves out

A few rules are left out on purpose, because they affect very few people and would make the tool harder to use. If one of them applies to you, your tax software will handle it.

• Limits on very large gifts. Cash gifts can’t add up to more than 60% of your AGI. For most donated items the limit is 50%, and for stock or property that has gone up in value it’s 30%. Anything over the limit carries forward for up to five years. The calculator assumes you’re under these limits, which is true unless you give away a large share of your income.
• The top tax bracket. Starting in 2026, people in the 37% bracket get a slightly smaller benefit from itemized deductions under a new limit. The calculator doesn’t model it.
• State returns. The calculator covers your federal return only, and states set their own rules for itemizing.
• Married filing separately. If one spouse itemizes, the other has to itemize too.

Here is what the calculator does apply every time:

• 2026 standard deduction amounts, with the extra for age and blindness
• SALT cap of $40,400, and how it shrinks at high incomes
• Medical bills: only the part above 7.5% of income counts
• Charity gifts: only the part above 0.5% of income counts
• Cash-gift deduction of $1,000 or $2,000 for people who don’t itemize

Those five rules settle the standard deduction vs itemized question for nearly everyone.

Who usually itemizes in 2026, and who does not

Itemized deductions tend to win for:

• people in the early years of a mortgage, when most of each payment is interest
• homeowners in states with high income or property taxes, now that the SALT cap is $40,400
• households that give several thousand dollars a year, especially when donated items are counted at their real value
• anyone with very large medical bills that year

The standard deduction tends to win for:

• renters
• people in states with no income tax
• couples 65 or older with a paid-off home
• anyone who gives a few hundred dollars a year

For that second group, the $1,000 or $2,000 cash-gift deduction is the only tax break for giving, and it only covers cash.

Your state return can work differently. Some states let you itemize on your state return even if you take the standard deduction on your federal return. Our guide to whether charitable donations reduce state taxes explains how that works.

Itemized vs standard deduction: a quick checklist

Before you trust any itemized deductions calculator, this one included, check your inputs:

• State and local taxes (SALT): use what you actually paid during 2026. That includes any balance you paid in April for 2025. A refund you got back doesn’t lower it.
• Property tax: use the bills you paid in 2026, whatever year they were for.
• Mortgage interest: use your lender’s number, and check that your loan is under $750,000.
• Gifts to charity: count every gift, both cash and donated items, and keep a receipt for each one.

Then compare your itemized total with your standard deduction plus the cash-gift deduction, and take whichever is bigger. When the two land within about $1,000 of each other, double-check the SALT and charity numbers. Those are the two lines with the most moving parts.

How to tip the comparison in your favor, legally

Say the itemized deductions calculator shows you’re a few thousand dollars short of itemizing. Two moves can close the gap.

Bunch two years of giving into one

Give two years’ worth of donations in one year, then give little or nothing the next. In the big year, you itemize. In the quiet year, you take the standard deduction plus the cash-gift deduction. You give the same total over two years but deduct more of it. Some counties also let you pay January’s property tax bill in December, which works the same way.

Count everything you already give

Donated items are easy to undercount when nobody writes them down. Think about a season of closet cleanouts, a garage full of baby gear, or the sofa that went to the Salvation Army. Half of the people who used Deductible Duck in 2025 tracked more than $1,809 in donations. Our Goodwill donation value guide and clothing value guide show what items are typically worth, and the IRS definition of fair market value explains the rule. For the paperwork you need at each dollar level, see how to keep your donation records audit-safe.

Deductible Duck keeps that list for you as you go: items, cash, stock and mileage, and you can attach a photo of the receipt to each donation. Pick an item and its condition, and the app shows fair market value estimates for almost 7,000 items, so you can choose the one that fits. At tax time it exports to TurboTax Desktop or prints a report for your CPA. Your first $1,000 of donations is free to track.

If you only care about the charity side, our charitable contribution tax deduction calculator shows what a single gift saves you. Our guide to the 2026 charitable deduction changes covers the new rules in more detail.
