Standard Deduction vs Itemized: How to Choose in 2026

2026 Standard Deduction: The Baseline You're Competing Against

The standard deduction is a flat dollar amount that reduces your AGI without requiring any documentation of actual expenses. For 2026, the IRS (per Revenue Procedure 2025-49 and the One Big Beautiful Bill Act adjustments) set the amounts as follows:

Two new elements make 2026 particularly important for older taxpayers. First, the existing additional standard deduction for age 65+ remains in place — $1,650 per qualifying person for single filers, $1,650 per eligible spouse for joint filers (so potentially $3,300 for a couple where both spouses are 65+). Second, under the One Big Beautiful Bill Act's temporary provisions, a $6,000 bonus deduction is available for taxpayers age 65 or older who meet income thresholds — this phases out at higher income levels and requires IRS guidance on the exact mechanics.

For most people, the conclusion is direct: if your combined Schedule A deductions don't exceed these standard deduction amounts, itemizing is a waste of time. The standard deduction is always available, requires zero documentation, and cannot trigger an audit related to deduction substantiation.

There are exceptions — some taxpayers are required to itemize regardless of the math. Non-resident aliens, dual-status aliens, and married taxpayers filing separately where the other spouse itemizes cannot take the standard deduction. These are relatively rare situations, but they apply.

Complete 2026 Itemized Deduction List (Schedule A, Line by Line)

Schedule A of Form 1040 organizes itemized deductions into six categories. Understanding each category — and the rules that limit it — is essential before deciding whether to itemize.

Medical and Dental Expenses (Schedule A, Line 4)

Only unreimbursed medical expenses exceeding 7.5% of AGI are deductible. Qualifying expenses include health insurance premiums not deducted elsewhere, prescription medications, hospital costs, dental work, vision expenses, mental health treatment, and long-term care insurance premiums (subject to age-based limits). Cosmetic surgery is generally not deductible unless it corrects a deformity from a disease or trauma.

The 7.5% floor is significant. A couple with $120,000 AGI must exceed $9,000 in medical expenses before any deduction begins. Only the amount above $9,000 is deductible. According to the Kaiser Family Foundation's 2025 Employer Health Benefits Survey, average annual employee premiums plus out-of-pocket costs reached approximately $8,900 for family coverage — meaning many families are tantalizingly close to the threshold but don't cross it. Those with major surgery, ongoing treatment for chronic conditions, or large dental/vision costs may clear it substantially.

State and Local Taxes — SALT (Schedule A, Lines 5–6)

This is the most significant change in the 2026 itemized deduction landscape. The TCJA of 2017 capped SALT deductions at $10,000 ($5,000 for married filing separately). The One Big Beautiful Bill Act raised this cap dramatically: for 2026, the SALT cap is $40,400 for most filers ($20,200 for married filing separately), with an income-based phase-down for taxpayers with MAGI above $500,000 (the cap phases to $10,000 for those above $600,000 MAGI).

The deductible SALT categories are: state and local income taxes (or sales taxes — you choose one), real property taxes, and personal property taxes. You cannot deduct both state income taxes and state sales taxes on the same return; you elect one or the other. Most high-income taxpayers in states with income tax elect the income tax option; residents of states without income tax (Texas, Florida, Nevada) typically benefit from deducting sales taxes.

For a family in New Jersey with $50,000 in combined state income tax and property tax bills, the new $40,400 cap is transformative. Under TCJA, they could only deduct $10,000. In 2026, they can deduct $40,400 — an additional $30,400 of itemized deductions. At the 24% bracket, that's $7,296 in additional tax savings compared to TCJA years.

According to the Tax Policy Center, approximately 14% of taxpayers currently itemize. The higher SALT cap is expected to increase that percentage meaningfully, particularly in high-tax states like California, New York, New Jersey, Connecticut, and Massachusetts.

Mortgage Interest (Schedule A, Lines 8–9)

Mortgage interest on debt up to $750,000 of qualifying acquisition debt is deductible (for loans originated after December 15, 2017). Pre-December 2017 loans grandfathered under the old $1,000,000 limit. Home equity loan interest is only deductible if the proceeds were used to buy, build, or substantially improve the home — not for consolidating credit card debt or funding vacations.

Two changes take effect in 2026. First, Private Mortgage Insurance (PMI) premiums are deductible again, having been reinstated under the OBBBA. Second, the $750,000 debt limit remains in place — no expansion. On a $750,000 mortgage at a 7% interest rate, the annual mortgage interest is approximately $52,500 in the first year of the loan, declining as the principal is paid down. For most homeowners in high-cost cities, this single deduction alone often justifies itemizing.

Interest on a second home is deductible under the same $750,000 combined limit. Points paid to obtain a mortgage are generally deductible in the year paid if you meet specific IRS requirements outlined in Publication 936.

Charitable Contributions (Schedule A, Lines 11–14)

Cash contributions to qualifying 501(c)(3) organizations are deductible up to 60% of AGI. Non-cash property donations (clothing, furniture, appreciated stock) are generally limited to 30% of AGI. Contributions to private foundations are limited to 30% of AGI for cash and 20% for appreciated property. Excess contributions carry forward up to five years.

The donation of appreciated stock or mutual funds is a particularly powerful strategy: you avoid the capital gains tax on the appreciation AND get a charitable deduction for the full fair market value. A donor who bought stock at $10,000 that is now worth $50,000 can donate the stock to charity, deduct $50,000, and pay zero capital gains on the $40,000 appreciation — saving potentially $8,000–$9,200 in capital gains taxes compared to selling the stock and donating the cash.

Note: cash donations of $250 or more require a written acknowledgment from the receiving charity. Non-cash donations over $500 require Form 8283. Donated vehicles, boats, and aircraft require a Form 1098-C and have separate deduction rules. All donated items must go to qualifying organizations — contributions to individuals, political organizations, or candidates are never deductible.

Casualty and Theft Losses (Schedule A, Line 15)

Since the TCJA, personal casualty and theft losses are only deductible if they occur in a federally declared disaster area. The deduction is limited to losses exceeding 10% of AGI plus a $100 floor per event. For those in federally declared disaster zones, this can be a significant deduction — but it is no longer available for ordinary theft or non-disaster casualty losses.

Other Itemized Deductions (Schedule A, Lines 16–28)

Miscellaneous itemized deductions — previously including unreimbursed employee expenses, tax preparation fees, and investment advisory fees — were eliminated by the TCJA for most taxpayers. The primary remaining "other" deductions are gambling losses (deductible only to the extent of gambling winnings) and certain impairment-related work expenses for disabled individuals.

The Decision: A Framework That Works for Every Situation

The arithmetic is simple: add up everything you can legitimately deduct on Schedule A. If that total exceeds your standard deduction amount, itemize. If not, take the standard deduction. But the judgment about whether to spend the time itemizing — particularly if you're close to the threshold — requires more nuance.

The Charitable Bunching Strategy: Itemize Every Other Year

Many people hover near the threshold where their itemized deductions are close to but not reliably above the standard deduction. For this group, the optimal strategy isn't choosing one method permanently — it's bunching deductions to alternate between itemizing in high-deduction years and taking the standard deduction in others.

The most controllable deduction for bunching is charitable giving. Instead of donating $6,000 per year for two years ($12,000 total), donate $12,000 in year one and nothing in year two. In year one, you have $12,000 of charitable giving that may push you over the standard deduction threshold when combined with mortgage interest and taxes. In year two, you take the standard deduction.

A Donor-Advised Fund (DAF) makes bunching more practical and more strategic. You contribute two or three years of charitable giving to a DAF in one tax year, take the full deduction that year, and distribute the grants to charities over multiple years. The Fidelity Charitable Gift Fund, Schwab Charitable, and Vanguard Charitable are the three largest DAF sponsors; each requires a minimum initial contribution of $5,000.

Consider accelerating other deductible expenses into a planned itemizing year: prepaying your January state estimated tax in December, timing elective medical procedures, and timing large capital projects on a rental property. The goal is to concentrate deductions into one year to clear the standard deduction hurdle, then rely on the standard deduction in the alternating year.

How the New $40,400 SALT Cap Changes Who Should Itemize in 2026

Before the TCJA in 2018, roughly 30% of taxpayers itemized. After the TCJA doubled the standard deduction and capped SALT at $10,000, itemization dropped to approximately 14%, according to Tax Policy Center analysis. The OBBBA's SALT increase to $40,400 is expected to increase the percentage of itemizers meaningfully, particularly in high-tax coastal states.

The states most affected by the SALT cap increase, where a disproportionate number of households paid more than $10,000 in combined state income and property taxes, are:

• New Jersey — average property tax of $9,803/year; state income tax rates up to 10.75%
• Connecticut — median property tax among the highest in the nation; 6.99% top income tax rate
• New York — NYC residents face combined state+city income tax up to 14.776%
• California — 13.3% top state income tax rate; median property taxes offset by Proposition 13 limits
• Massachusetts — 5% flat income tax; surtax on income above $1M (now 9%)

For a married couple in these states with combined state taxes of $35,000, the shift from a $10,000 SALT cap to $35,000 in deductible SALT effectively adds $25,000 to their potential itemized deductions. At the 22% marginal rate, that's $5,500 in annual federal tax savings — enough to make itemizing clearly superior to the standard deduction for many households that previously couldn't benefit from it.

Important limitation: the SALT cap increase is temporary under current law, scheduled to reduce back to the standard deduction equivalent in 2030. Tax planning for 2027–2029 should factor in potential expiration.

Common Expenses That Are NOT Deductible on Schedule A

Tax software, tax preparers, and overconfident friends sometimes lead people to claim Schedule A deductions that the IRS disallows. The audit risk is real — the IRS matches Schedule A totals against population norms by AGI range. Amounts that appear outsized for your income level trigger scrutiny. Here are items that are frequently — and incorrectly — claimed:

• Homeowners insurance — not deductible on Schedule A for a personal residence (only deductible as a Schedule E expense for rental property)
• Mortgage principal payments — only the interest portion of a mortgage payment is deductible, not principal
• Home improvements — kitchen remodels, additions, and landscaping are capital improvements that increase your home's basis, not deductible expenses (though they can reduce capital gains when you sell)
• Utilities for a personal home — gas, electric, water, and cable are not deductible; only deductible if you have a qualifying home office (Schedule C) or rental property (Schedule E)
• Charitable contributions to individuals — GoFundMe campaigns, gifts to friends or family in need, and contributions to non-qualified organizations are never deductible
• Political contributions — donations to political candidates, parties, or PACs are explicitly non-deductible under IRC Section 276
• Fees at private clubs — country club dues, gym memberships, and similar fees are not deductible as charitable contributions even if the organization is a non-profit
• Federal income taxes paid — Schedule A allows state and local taxes, but federal income taxes are specifically excluded from the SALT deduction

The Three Questions That Determine Your Optimal Choice

Before finalizing your deduction method for any tax year, work through these three questions:

Question 1: Do you have a mortgage? Mortgage interest is the single largest itemized deduction for most households. A $600,000 mortgage at today's rates generates $40,000+ in interest in the early years — more than the standard deduction for single filers on its own. Homeowners with large recent mortgages almost always benefit from itemizing.

Question 2: What is your combined state tax burden? Add your total state income or sales tax plus property taxes. If the result exceeds $20,000 as a single filer or $30,000 as a married filer, the new SALT cap is allowing you to deduct more than before — and itemizing deserves serious consideration, especially combined with mortgage interest.

Question 3: Did you have an unusual year? Major medical events, significantly elevated charitable giving, casualty losses in a federally declared disaster, or large miscellaneous deductible losses can temporarily push someone who normally takes the standard deduction into itemizing territory. Re-evaluate every year — don't assume last year's answer is correct.
