Your 2026 Tax Deductions Checklist: What You Can Actually Claim

Standard Deduction vs. Itemized Deductions: The First Step in Your Tax Deductions Checklist

The standard deduction is a fixed dollar amount every taxpayer can subtract from income, with no paperwork required. For 2026, it is $16,100 for single filers and those married filing separately, $24,150 for heads of household, and $32,200 for married couples filing jointly, per the IRS. Filers who are 65 or older, or blind, can add an extra amount on top of that base figure.

Itemizing means adding up specific deductible expenses on Schedule A instead of taking the flat amount. You should itemize only when your total qualifying expenses exceed your standard deduction. If your itemized total falls short, the standard deduction saves you more, and the rest of this checklist has no effect on your return that year.

Run rough numbers before you assume either way. Add up your likely mortgage interest, state and local taxes, and charitable gifts first. If that estimate sits near your standard deduction, work through the full checklist below before you decide. See how much tax you'll actually pay this year to understand how a deduction changes your bracket and your bill.

Housing Deductions: Mortgage Interest and the SALT Cap

Mortgage interest and state and local taxes are the two itemized deductions most homeowners rely on. Both only count if you itemize on Schedule A instead of taking the standard deduction.

Mortgage interest is deductible on loan balances up to $750,000 ($375,000 if married filing separately) for debt taken out after December 15, 2017, according to IRS guidance. Loans that closed on or before that date keep a higher $1,000,000 cap. Interest on a home equity loan only counts if you used the money to buy, build, or substantially improve the home that secures it. See our mortgage tax implications guide for how this deduction interacts with paying down your loan early.

State and local taxes, known as the SALT deduction, cover property tax plus either state income tax or state sales tax, whichever you choose. The combined cap for 2026 is $40,400 ($20,200 if married filing separately). The cap phases down for taxpayers with modified adjusted gross income above $505,000 ($252,500 if married filing separately), though it never drops below $10,000.

A common mistake catches taxpayers who have not revisited this deduction since before 2025: they assume the SALT cap is still $10,000 and skip claiming state and local taxes that would now clear the threshold. The cap roughly quadrupled starting with the 2025 tax year, so a household that could not benefit from itemizing SALT a few years ago may benefit now, especially in a high-tax state where property tax alone can approach the new limit.

Charitable Contributions

Gifts to a qualified 501(c)(3) organization are deductible if you itemize, and they follow their own rules: an income-based cap, a documentation threshold, and a floor for smaller gifts. Cash gifts, non-cash items valued at fair market value, and even mileage driven for volunteer work can all count.

Save proof for every gift you plan to claim. The IRS requires written acknowledgment for any single cash gift of $250 or more, and Form 8283 for non-cash gifts over $500. Our church donations and tax deductions guide covers the exact AGI caps, the new floor on itemized giving, and how bunching two years of gifts into one donor-advised fund contribution can push your itemized total past the standard deduction.

Medical Expenses Above the AGI Floor

Medical and dental expenses are deductible only for the portion that exceeds 7.5% of your adjusted gross income, per the IRS instructions for Schedule A. That floor rules out this deduction for most filers in an ordinary year.

The math works like this: with $80,000 in AGI, the first $6,000 of medical costs, 7.5% of $80,000, is not deductible. Only spending above that floor counts. A single major event, like surgery, a hospital stay, or a year of orthodontia, is usually what pushes a household over the line.

Qualifying costs include payments to doctors, dentists, and other licensed providers, prescription drugs, and health insurance premiums you pay yourself. Cosmetic procedures and general health items like vitamins do not count unless a doctor prescribed them for a diagnosed condition. If you know a large medical expense is coming, timing it into one calendar year, rather than spreading it across two, can be what gets you over the 7.5% floor at all.

Above-the-Line Deductions: Student Loans, HSAs, and Retirement Accounts

Above-the-line deductions reduce your income before you choose between the standard deduction and itemizing, so you get them either way. That makes them worth checking even if you plan to take the standard deduction this year.

Student loan interest is deductible up to $2,500 a year without itemizing. For 2026, the deduction phases out for single filers with modified adjusted gross income between $85,000 and $100,000, and for joint filers between $175,000 and $205,000, according to the IRS. Above the top of that range, the deduction disappears completely.

A Health Savings Account contribution is deductible even without itemizing, and it is the only deduction that also produces tax-free growth and tax-free qualified withdrawals. You need a high-deductible health plan to qualify. For 2026, the IRS caps contributions at $4,400 for self-only coverage and $8,750 for family coverage. See our HSA vs. FSA comparison if you are choosing between the two account types during open enrollment.

Traditional retirement contributions also lower your taxable income ahead of the standard-versus-itemized choice. A traditional 401(k) contribution is deductible up to $24,500 for 2026, or $32,500 with the catch-up contribution at age 50 or older. A traditional IRA contribution can also be deductible, though the deduction phases out if you or your spouse is covered by a workplace plan; see our 2026 IRA contribution limits guide for the exact income ranges.

Educator Expenses and Self-Employment Deductions

Eligible K-12 educators can deduct out-of-pocket classroom spending without itemizing. For 2026, the IRS allows up to $350 in qualifying purchases like books, supplies, and classroom equipment, and married educators who both teach can each claim their own $350. Starting in 2026, educators can also itemize classroom expenses above that amount on Schedule A instead, if their total itemized deductions clear the standard deduction.

Self-employed taxpayers get a different set of above-the-line write-offs that W-2 employees do not. Half of your self-employment tax is deductible regardless of whether you itemize, since that half mirrors the employer-side payroll tax a traditional job would otherwise cover. Self-employed health insurance premiums, and contributions to a solo 401(k) or SEP-IRA, are also generally deductible. These rules get complicated fast, so a self-employed filer with real business income should confirm the details with a tax professional or IRS Publication 535 rather than rely on this checklist alone.

If You Have Self-Employment Income

Everything above is the individual filer's checklist — Schedule A and the above-the-line deductions everyone can reach. If you also have 1099 or business income, a separate and generally larger set of deductions runs on Schedule C before any of this applies, and the One Big Beautiful Bill Act changed the rules for solo filers in three ways worth knowing.

The qualified business income deduction is now permanent. Section 199A was scheduled to expire after 2025; it no longer does, which removes the planning uncertainty that hung over every pass-through business. From 2026 there is also a minimum deduction of $400 for taxpayers with at least $1,000 of qualified business income from an active business they materially participate in, and the phase-in thresholds rose to roughly $201,775 for single filers and $403,500 for joint filers. Note that the $400 is a deduction rather than a refund — it is worth about $48 in the 12% bracket, not $400.

The second change is quieter and affects what paperwork arrives: the Form 1099-NEC filing threshold rose from $600 to $2,000 for 2026, and the 1099-K threshold sits at over $20,000 across more than 200 transactions. Neither changes what you owe. Self-employment tax starts at $400 of net earnings, and the IRS requires business income to be reported whether or not an information return is issued.

The third is that a business deduction is worth more to you than an itemized one. Schedule C expenses reduce the profit that both income tax and self-employment tax are calculated on, so a deducted dollar saves your marginal rate plus about 14.13% — roughly 26 cents in the 12% bracket. See our QBI deduction guide and the self-employed deductions list, and run the numbers in the self-employment tax calculator.

How to Use This Tax Deductions Checklist

Use this tax deductions checklist as a starting point, not a finished tax return. Walk through each item above, note whether it applies to you, then add up your itemizable total and compare it against your standard deduction.

Most single filers, and many married couples, still come out ahead with the standard deduction, especially now that it rises with inflation every year. Homeowners with a large mortgage, filers in high-tax states affected by the new $40,400 SALT cap, and households with a major medical or charitable year are the ones most likely to benefit from itemizing instead.

Keep documentation year-round rather than scrambling every April. Save mortgage interest statements, property tax bills, medical receipts, and charitable acknowledgment letters as they arrive. Recheck this checklist every year, since dollar limits and phase-out ranges adjust for inflation and can change again if Congress passes new tax legislation. When your situation gets complicated, such as self-employment income, a big life event, or a deduction close to a phase-out line, a CPA or enrolled agent earns their fee.
