Choosing between the standard and itemized deductions comes down to a single comparison: add up your qualifying expenses after the 2026 caps and floors, then take whichever number beats the flat standard deduction for your filing status. For the 2026 tax year, that flat amount is $16,100 for single filers and $32,200 for married couples filing jointly, so itemizing only pays off when your eligible expenses clear those thresholds.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Most taxpayers land below those thresholds and take the standard deduction. The question is whether you’re one of the exceptions.
The 2026 Standard Deduction Numbers
You claim the standard deduction simply by not filing Schedule A. For 2026, the amounts are:2Internal Revenue Service. Rev. Proc. 2025-32
- Single: $16,100
- Married filing jointly or surviving spouse: $32,200
- Head of household: $24,150
- Married filing separately: $16,100
If you’re 65 or older, legally blind, or both, add $1,650 per qualifying condition if you’re married or a surviving spouse, or $2,050 per condition if you’re unmarried.2Internal Revenue Service. Rev. Proc. 2025-32 These stack. A single filer who is both 65 and blind gets $4,100 added to the base $16,100, for $20,200 total. The bonus applies only if you take the standard deduction, so you forfeit it when you itemize. That matters when your itemized total sits just above the base standard deduction but below your enhanced amount.
What You Can Actually Itemize in 2026
Itemizing means replacing the flat deduction with a list of specific expenses on Schedule A of Form 1040.3Internal Revenue Service. Instructions for Schedule A (Form 1040) The main categories are medical and dental expenses, state and local taxes, home mortgage interest, charitable contributions, casualty and theft losses from federally declared disasters, and investment interest.
Miscellaneous deductions that used to sit on Schedule A subject to a 2% AGI floor, like unreimbursed employee expenses, tax preparation fees, and investment advisory costs, are gone permanently.4Office of the Law Revision Counsel. 26 USC 67 – 2-Percent Floor on Miscellaneous Itemized Deductions Don’t count on them coming back.
The SALT Cap
State and local taxes, meaning state income or sales taxes plus real estate and personal property taxes, are capped at $40,400 for 2026 for single and joint filers, and $20,200 for married filing separately.5Office of the Law Revision Counsel. 26 USC 164 – Taxes The cap phases down for higher earners: if your modified adjusted gross income exceeds $505,000 ($252,500 for married filing separately), the $40,400 ceiling drops by 30 cents for every dollar of income above the threshold, but it never falls below $10,000. A joint filer earning above roughly $606,000 hits that $10,000 floor. Both the cap and the income threshold rise 1% per year through 2029, then the cap reverts to $10,000 for everyone in 2030.
The Medical Expense Floor
Only the portion of your medical and dental costs above 7.5% of your AGI is deductible.6Internal Revenue Service. Publication 502 – Medical and Dental Expenses With $100,000 of AGI, your first $7,500 in medical spending produces nothing. Spend $12,000 and you deduct $4,500. This category usually helps in years with major procedures or serious illness, not routine care.
Mortgage Interest
You can deduct interest on up to $750,000 of mortgage debt used to buy, build, or substantially improve your primary or second home ($375,000 if married filing separately).7Internal Revenue Service. Real Estate Taxes, Mortgage Interest, Points, Other Property Expenses Home equity loan interest qualifies only if you used the money for home improvements. Using it to pay off credit cards or cover personal expenses does not count.
Charitable Contributions
Cash donations to qualifying charities are capped at 60% of AGI. Donations of appreciated property held longer than a year are generally capped at 30% of AGI. Excess amounts carry forward up to five years.
New for 2026, only the portion of charitable contributions exceeding 0.5% of your AGI is deductible. On $200,000 of AGI, your first $1,000 of giving produces no benefit. Taxpayers in the top 37% bracket also face a cap that limits the effective value of itemized deductions to roughly 35%, reducing the benefit by about 5.4% for the highest earners.
When You Don’t Get to Choose
A few situations remove the choice entirely.
If you’re married filing separately and your spouse itemizes, you must itemize too.8Internal Revenue Service. Itemized Deductions, Standard Deduction The second spouse cannot take the standard deduction even with almost nothing to itemize. That trap often makes married filing separately worse than it looks.
Nonresident aliens generally can’t claim the standard deduction and must itemize.9Internal Revenue Service. Nonresident – Figuring Your Tax The one narrow exception is for students and business apprentices from India under the U.S.-India income tax treaty.10Internal Revenue Service. Tax Treaties Taxpayers filing a short-year return because of a change in accounting period also lose the standard deduction, though that mostly affects businesses.11Internal Revenue Service. Topic No. 551, Standard Deduction
Making the Call
In concept the decision is simple. Total your itemized deductions after applying every cap and floor. Compare that total to your standard deduction (including any age or blindness bonus). Take the larger number. Tax software runs the comparison automatically once you’ve entered your expenses.
The judgment call comes when your itemized total lands just above the standard deduction. A few hundred dollars in savings may not justify keeping receipts, statements, and documentation for every expense, all of which you need to hold onto for at least three years after filing.12Internal Revenue Service.

Bunching Deductions
If your deductible expenses hover near the standard deduction year after year, you can concentrate two or three years’ worth of timing-flexible expenses, especially charitable contributions, into a single tax year. That year’s itemized total clears the threshold by a wide margin; in the off years you take the standard deduction. Over the cycle, your combined deductions come out higher than they would from modest itemizing every year.
Donor-advised funds make bunching straightforward for charitable giving. You contribute a lump sum in the bunching year and deduct it that year, then recommend grants to charities over the following years. Watch the AGI ceilings, though: if you bunch too aggressively, the excess carries forward up to five years rather than disappearing.
Deductions You Get Either Way
Not every deduction depends on this choice. Several sit “above the line” and reduce your adjusted gross income whether you itemize or not: traditional IRA contributions, student loan interest up to $2,500, health savings account contributions, and self-employment tax. Claim these regardless of which method you choose.
The qualified business income deduction under Section 199A also operates independently. If you earn income through a sole proprietorship, partnership, or S corporation, you can deduct up to 20% of qualified business income whether you itemize or take the standard deduction. The One Big Beautiful Bill Act made this deduction permanent.
Also new for 2026, taxpayers who take the standard deduction can claim a charitable deduction of up to $1,000 ($2,000 for joint filers) for cash donations to qualifying organizations, though contributions to donor-advised funds don’t count. It won’t change the analysis for large donors, but it restores a modest charitable benefit for the majority of filers who never itemize.
