Standard Deduction vs. Itemizing: When Itemizing Actually Wins

Itemizing used to be a middle-class ritual. You kept a shoebox, you saved the charity receipts, and in February you added it all up. Then the 2017 law roughly doubled the standard deduction and capped the biggest itemized category, and the ritual stopped paying. For most households it now produces a smaller number than the free one the IRS hands out for doing nothing.

But "most" isn't "all," and the SALT cap moved sharply upward starting with tax year 2025, which put a specific group of people back in play. Here's how to tell in about ten minutes whether you're one of them.

What the standard deduction is worth

For tax year 2026 — the return you'll file in early 2027 — the IRS has set it at:

• $16,100 for single filers and married filing separately
• $32,200 for married couples filing jointly and surviving spouses
• $24,150 for heads of household

For tax year 2025, the return most people filed this spring, the figures were $15,750, $31,500, and $23,625.

There's an add-on if you're 65 or older or blind. For 2025 that was $1,600 per qualifying condition, rising to $2,000 if you're unmarried and not a surviving spouse — and both spouses can qualify separately, and age and blindness stack. A couple both over 65 collects it twice. The IRS defines "65 or older" generously: for 2025 you counted if you were born before January 2, 1961, which quietly includes people whose birthday is January 1.

Separately, and confusingly, there's now an additional $6,000 deduction for filers age 65 and over, introduced by the 2025 legislation and phased out at higher incomes. It's not the same thing as the age-65 addition to the standard deduction. The IRS page "New and enhanced deductions for individuals" is the place to check the eligibility rules and the income limits before you count on it.

What itemizing actually requires

Schedule A, and records. The categories that survive, with the limits that matter:

• State and local taxes — income or sales tax, plus property tax. Capped at $40,000 for 2025 ($20,000 married filing separately). The cap is reduced if your modified AGI tops $500,000 ($250,000 filing separately), but never falls below $10,000.
• Mortgage interest — on up to $750,000 of debt ($375,000 filing separately) for loans taken after December 15, 2017. Older loans keep the older, higher limits of $1,000,000 and $500,000.
• Medical and dental expenses — but only "the part of your medical and dental expenses that exceeds 7.5% of the amount of your adjusted gross income." On a $60,000 AGI, the first $4,500 is invisible.
• Charitable contributions, subject to AGI-based ceilings.
• Casualty and theft losses, now limited to federally declared disaster areas.
• Gambling losses, up to the amount of your gambling winnings and no further.

That SALT number is the one that changed. A cap that sat at $10,000 for years is what killed itemizing for homeowners in New Jersey, New York, California and Illinois. At $40,000, a household paying $12,000 in state income tax and $9,000 in property tax gets to count all $21,000 instead of half of it.

Where the line actually falls

The rule from the IRS is plain: itemize "if the total amount of your allowable itemized deductions is greater than your standard deduction." What that phrasing hides is that only the excess is worth anything. The first $32,200 of a joint filer's itemized deductions buys exactly what the standard deduction would have handed over for free.

A married couple in 2026, both working, in a state with an income tax:

• State income tax withheld: $9,000
• Property tax: $7,000
• Mortgage interest: $14,000
• Charitable giving: $3,000
• Total itemized: $33,000

Against a $32,200 standard deduction, they should itemize — and the entire reward is the $800 of excess. In the 22% bracket that is $176. A year of tracking, a longer return, and $176.

This is the arithmetic almost nobody runs, and it's why "I itemize" is so often a statement about identity rather than money. Being $800 over the line is not a windfall. Being $8,000 over is.

The other way to clear the bar is a medical year. A single filer with $60,000 of AGI has a 7.5% floor of $4,500. Rack up $19,000 in bills after insurance — a surgery, a long hospitalization, a parent's care you paid for — and $14,500 is deductible. Add $6,000 of state and property tax and you're at $20,500 against a $16,100 standard deduction. Medical expenses are the single most common reason an otherwise ordinary household itemizes exactly once.

Bunching, for people who are close

If you land just under the standard deduction every year, you get nothing every year. The fix is to stop spreading deductible spending evenly.

Two years of charitable giving in one calendar year, a January property tax installment paid in December, an elective procedure scheduled before year-end rather than after — push them together and one year clears the bar while the other takes the standard deduction. A couple giving $12,000 a year and sitting at $30,000 of itemized deductions gets zero benefit twice; giving $24,000 in one year and nothing the next gets $42,000 in year one and the $32,200 standard deduction in year two.

Timing charitable gifts this way is legitimate. Timing a state tax payment is legitimate. Prepaying a medical bill for services not yet rendered is not, and neither is claiming a December donation you actually made in January.

Rules that override the choice

A handful of filers don't get to choose. The IRS says you cannot take the standard deduction if "you are a married individual filing as married filing separately whose spouse itemizes deductions." That one is a trap in divorces and separations: if your spouse itemizes and you don't coordinate, your standard deduction vanishes and you're itemizing whatever you have, which may be very little. Get that in writing before either return is filed.

Nonresident and dual-status aliens, filers with a short tax year from an accounting period change, and estates, trusts and partnerships are also outside the standard deduction.

Don't spend the year finding out

The mistake worth naming: keeping every receipt for twelve months, then discovering in March that you were $4,000 short and it was all for nothing.

You don't need receipts to know the answer. Three of the four big categories are knowable in advance — your mortgage interest is roughly predictable, your property tax bill arrives on a schedule, your state withholding is on every pay stub. Add those in October. If the total is within a few thousand of your standard deduction, the year is worth managing. If it's $12,000 against a $32,200 standard deduction, stop tracking, take the standard deduction, and give to charity for the reasons you actually give to charity.

And the corollary: never take on a bigger mortgage for the interest deduction. You are paying a dollar of interest to a bank to avoid twenty-two cents of tax. That trade has never once been good.

The ten-minute check

1. Write down your standard deduction for your filing status and year.
2. Add your state income or sales tax plus property tax, capped at $40,000.
3. Add the mortgage interest from Form 1098.
4. Add charitable giving, and medical expenses above 7.5% of AGI if it was that kind of year.
5. Compare. If itemizing wins by less than about $1,000, take the standard deduction and keep your Saturday — or plan to bunch next year and win properly.

Tax software runs this comparison automatically and picks the larger number, which is why the calculation matters less than the planning. The decision that's actually yours is made in October, not April. (General information, not tax advice.)
