The Basics: What Are Deductions?

Tax deductions reduce your taxable income — the number used to calculate how much federal income tax you owe. If you earn $90,000 and claim the $16,100 standard deduction (single, 2026), you are taxed on $73,900 instead of $90,000. At a 22% marginal rate, that deduction saves you $3,542 in federal taxes.

Every taxpayer chooses between two approaches: the standard deduction (a flat amount set by the IRS based on your filing status) or itemized deductions (a list of specific qualifying expenses you actually paid). You get whichever is larger — but you cannot take both. The decision is purely mathematical: add up your itemizable expenses and compare them to the standard deduction. Take whichever number is bigger.

The Standard Deduction in 2026

The standard deduction is a fixed dollar amount that reduces your taxable income with no documentation required. You do not need receipts, calculations, or special forms. The amounts for 2026 — and, for anyone still filing a 2025 return, 2025 — are:

If you are 65 or older or blind, you receive an additional standard deduction: for 2026, $2,050 if you are single or a head of household, or $1,650 per qualifying condition if you are married. A married couple who are both 65 or older gets $35,500 ($32,200 + 2 × $1,650). On top of that, for 2025 through 2028 each person 65 or older can claim the new $6,000 senior deduction whether or not they itemize; it phases out above $75,000 of modified AGI ($150,000 for joint filers).

What Qualifies as an Itemized Deduction

Itemized deductions require you to list specific expenses on Schedule A of your tax return. Here are the major categories and their rules.

State and Local Taxes (SALT) — Capped at $40,400 in 2026

You can deduct state income taxes (or state sales taxes — you choose one but not both), local property taxes, and personal property taxes. The 2025 tax law raised the cap from $10,000 to $40,000 for 2025 and $40,400 for 2026 ($20,200 if married filing separately). It rises 1% a year through 2029 and, under current law, returns to $10,000 in 2030.

High earners get less of the increase: the cap shrinks by 30% of modified AGI above $505,000 (2026), but never below $10,000. At $600,000 of MAGI, for example, the cap is $40,400 − 30% × $95,000 = $11,900. For most homeowners in high-tax states like New York, New Jersey, California and Connecticut, the higher cap means their full property and income tax bill is deductible again — which is why itemizing is back on the table for many of them.

Mortgage Interest

Interest paid on mortgage debt up to $750,000 (for loans originated after December 15, 2017) is deductible. For mortgages predating that date, the limit is $1 million. Home equity loan interest is deductible only if the loan was used to buy, build, or substantially improve the home securing the loan. Interest on a home equity loan used to pay credit card debt or fund a vacation is not deductible.

Charitable Contributions

Donations to qualified 501(c)(3) organizations are deductible if you itemize. Starting in 2026, only the part of your giving above 0.5% of your AGI counts, and cash donations stay deductible up to 60% of AGI. Donated property (clothing, household items, vehicles) is deductible at fair market value. Donations above $250 require a written acknowledgment from the charity. Stock donations of appreciated securities avoid capital gains tax and provide a deduction at full market value — one of the most tax-efficient giving strategies available.

Medical and Dental Expenses

You can deduct medical and dental expenses that exceed 7.5% of your adjusted gross income. If your AGI is $80,000, only medical expenses above $6,000 qualify. This means you need substantial medical costs — major surgery, chronic illness management, significant dental work — for this deduction to provide value. Expenses covered by insurance do not count.

Casualty and Theft Losses

Since the TCJA, personal casualty losses are deductible only if they result from a federally declared disaster. The deduction is limited to the loss amount minus $100, minus 10% of your AGI. General theft or unreimbursed property damage no longer qualifies.

The Break-Even Analysis: When Itemizing Wins

The math is simple: if your total itemizable expenses exceed the standard deduction, itemize. If not, take the standard deduction. Here is a practical example for a married couple.

Example: Married Couple, $150,000 Income (2026 Rules)

Assume their AGI is $150,000 and the $4,500 is cash given directly to charities. Under the 2026 rules this couple deducts every dollar of their $14,000 in state and local taxes, yet itemizing still falls $50 short of the $32,200 standard deduction. The new charitable rules widen the gap: as itemizers, the first 0.5% of AGI ($750) of their giving earns nothing; as standard-deduction filers, they can deduct up to $2,000 of cash gifts on top of the standard deduction. The standard route wins by $2,050 of deductions — about $451 of federal tax at their 22% marginal rate. Under the old $10,000 SALT cap that applied from 2018 through 2024, only $10,000 of their taxes would have counted.

Who Typically Benefits From Itemizing

• Homeowners with large mortgages in high-cost areas where mortgage interest alone exceeds $15,000 to $20,000 per year
• Generous charitable givers who donate more than $5,000 to $10,000 annually, especially those who donate appreciated stock
• People with extraordinary medical expenses — major surgeries, chronic conditions, long-term care — that push past the 7.5% AGI floor
• Taxpayers in high-tax states who can now deduct up to $40,400 of state and local taxes (2026) and have a mortgage or large gifts to stack on top
• Married couples where one spouse has high medical costs may benefit from filing separately to lower the 7.5% AGI threshold

The Bunching Strategy: Making Itemizing Work

If your itemizable expenses are close to but below the standard deduction, the bunching strategy can tip the balance. The idea is to accelerate two or more years of deductible expenses into a single year — itemize that year, then take the standard deduction in the alternate year.

How It Works

Instead of donating $5,000 to charity each year, you donate $10,000 every other year. In the "bunching" year, your itemized deductions are $5,000 higher, potentially pushing you over the standard deduction threshold. In the alternate year, you take the standard deduction and pay nothing extra.

Donor-Advised Funds

A donor-advised fund (DAF) makes bunching even more powerful. You contribute a large lump sum to the DAF — say, three to five years of planned charitable giving — and take the full deduction in the contribution year. Then you recommend grants from the DAF to your chosen charities over the following years. The charities receive steady support, and you get the tax benefit of a concentrated deduction.

Above-the-Line Deductions: Available to Everyone

Some deductions — called "above-the-line" or "adjustments to income" — reduce your adjusted gross income regardless of whether you itemize or take the standard deduction. These are available to all taxpayers and can be stacked on top of either approach.

• Traditional IRA contributions (up to $7,500 for 2026, or $8,600 if 50+, subject to income limits if covered by a workplace plan)
• HSA contributions ($4,400 self-only, $8,750 family in 2026)
• Student loan interest (up to $2,500)
• Self-employment tax (the employer-equivalent portion — 50% of SE tax)
• Educator expenses (up to $300 for K-12 teachers)

These deductions are especially valuable because they also reduce your AGI, which can affect eligibility for other tax benefits, credits, and deductions that phase out at higher AGI levels.

What the 2025 Tax Law Changed

The standard deduction never shrank. Public Law 119-21, signed on July 4, 2025, made the larger standard deduction permanent and raised it again — to $15,750 single and $31,500 joint for 2025, and $16,100 and $32,200 for 2026, with inflation adjustments after that. It also rewired the itemize-or-not decision in four ways:

• A bigger SALT cap: $40,400 for 2026 ($20,200 married filing separately), shrinking for modified AGI above $505,000 and scheduled under current law to return to $10,000 in 2030.
• A charitable deduction for non-itemizers: from 2026, up to $1,000 ($2,000 joint) of cash gifts to qualifying charities on top of the standard deduction. Gifts to donor-advised funds don't count.
• A floor and a cap for itemizers: from 2026, only charitable gifts above 0.5% of AGI are deductible, and for people in the 37% bracket the tax value of itemized deductions is capped at 35 cents per dollar.
• A senior deduction: $6,000 per person age 65 or older for 2025 through 2028, available whether or not you itemize; it phases out above $75,000 of modified AGI ($150,000 joint).

The net effect: more homeowners in high-tax states will find itemizing worthwhile again, while modest givers who take the standard deduction get a charitable write-off for the first time since 2021. Run both totals every year — the answer can flip as your mortgage, taxes and giving change.
