2025-2026 Tax Deductions Guide: Complete List of New Changes and How to Maximize Your Deductions

The 2025-2026 tax year brings meaningful updates to deductions that could put more money back in your pocket. From adjusted standard deduction amounts to expanded credits, understanding what changed — and what stayed the same — is the fastest way to reduce what you owe before the filing deadline hits.

Standard Deduction Amounts for 2025: What You Need to Know First

Before diving into itemized deductions, the standard deduction is where most taxpayers start — and for good reason. The IRS adjusts these amounts annually for inflation, and the 2025 figures are slightly higher than 2024 across all filing statuses.

For the 2025 tax year (returns filed in 2026), the standard deduction amounts are:

• Single filers: $15,000 (up from $14,600 in 2024)
• Married filing jointly: $30,000 (up from $29,200 in 2024)
• Head of household: $22,500 (up from $21,900 in 2024)

These increases sound modest, but on a marginal tax rate basis, that extra $400–$800 in deduction room can translate to real dollars saved depending on your bracket. The question every filer should ask: does itemizing beat your standard deduction? Use a free tax deduction calculator to run both scenarios before you commit to either approach.

Who Should Still Consider Itemizing in 2025?

High-income earners, homeowners with significant mortgage interest, and taxpayers with large charitable contributions or medical expenses are still the primary candidates for itemizing. If your deductible expenses don't exceed the thresholds listed above, the standard deduction wins automatically — no additional documentation required.

Key Changes to Itemized Deductions for 2025-2026

Several itemized deduction categories have seen either rule changes, threshold adjustments, or inflation-related updates. Here's a breakdown of the most impactful ones.

State and Local Tax (SALT) Deduction Cap Remains at $10,000

The $10,000 cap on state and local tax deductions — originally introduced by the Tax Cuts and Jobs Act (TCJA) — remains in place for 2025. This cap applies to the combined total of state income taxes (or sales taxes) and property taxes. For residents of high-tax states like California, New York, and New Jersey, this continues to be a significant limitation.

There's active legislative discussion about whether this cap will be raised or eliminated when TCJA provisions come up for renewal in late 2025, but nothing has been enacted as of the current filing period. Stay tuned to IRS.gov tax news updates for any mid-year guidance changes.

Medical Expense Deduction: The 7.5% AGI Threshold Continues

The medical expense deduction threshold remains at 7.5% of your adjusted gross income (AGI) for 2025. That means if your AGI is $80,000, only medical expenses exceeding $6,000 are deductible. This threshold was temporarily reduced from 10% in prior years and has since been made permanent at the 7.5% level — a benefit for filers with significant healthcare costs.

Qualifying expenses include premiums for health insurance (if you pay them yourself and aren't self-employed), prescription medications, dental and vision care, long-term care services, and even certain home modifications for medical necessity. Cosmetic procedures generally don't qualify unless medically required.

Mortgage Interest Deduction Limits Unchanged

The mortgage interest deduction cap — set at $750,000 of loan principal for mortgages originated after December 15, 2017 — remains unchanged for 2025. Homeowners with mortgages originated before that date may still qualify for the older $1 million limit. Interest on home equity loans is deductible only when the proceeds are used to buy, build, or substantially improve the home securing the loan.

Above-the-Line Deductions That Reduce Your AGI Directly

Above-the-line deductions (technically called "adjustments to income") are some of the most valuable deductions available because they reduce your AGI regardless of whether you itemize or take the standard deduction. Lower AGI can also unlock eligibility for other deductions and credits.

Student Loan Interest Deduction

For 2025, you can deduct up to $2,500 in student loan interest paid during the year. The deduction phases out for single filers with modified AGI between $80,000 and $95,000, and for married filing jointly filers between $165,000 and $195,000. These phase-out thresholds are adjusted slightly upward for 2025 compared to prior years.

IRA Contributions and Retirement Savings Deductions

Contributing to a traditional IRA can reduce your taxable income dollar-for-dollar, subject to income limits if you or your spouse also have a workplace retirement plan. For 2025, the IRA contribution limit is $7,000 per person (or $8,000 for those age 50 and older, thanks to the catch-up contribution provision).

Self-employed individuals have access to even larger deductions through SEP-IRA or Solo 401(k) contributions — up to 25% of net self-employment income or $70,000, whichever is less. These are among the most powerful tax reduction strategies for freelancers and small business owners.

Self-Employed Health Insurance Deduction

If you're self-employed and pay your own health insurance premiums, 100% of those premiums are deductible as an above-the-line adjustment. This includes coverage for yourself, your spouse, dependents, and children under age 27. You can't claim this deduction for any month you were eligible to participate in an employer-sponsored plan — including a spouse's plan.

Business and Self-Employment Deductions: What Changed in 2025

Business owners and self-employed filers continue to have access to the broadest range of deductions available under the tax code. Several provisions warrant close attention this year.

Section 199A Qualified Business Income (QBI) Deduction

The 20% qualified business income deduction — another TCJA creation — is still available for pass-through business income in 2025. This deduction allows eligible self-employed individuals and small business owners to deduct up to 20% of qualified business income from sole proprietorships, partnerships, S-corporations, and certain trusts.

Phase-in limitations apply for "specified service trades or businesses" (SSTBs) like law, health, and consulting once taxable income exceeds $197,300 for single filers or $394,600 for joint filers in 2025. Below those thresholds, most self-employed filers qualify for the full 20% deduction.

This deduction is scheduled to expire after 2025 unless Congress acts. It represents one of the largest potential deduction losses on the horizon — worth running numbers on now using a QBI deduction calculator before year-end planning deadlines pass.

Home Office Deduction Updates

The simplified home office deduction method allows a deduction of $5 per square foot of dedicated office space, up to 300 square feet — a maximum of $1,500. The regular method, which calculates actual home expenses proportionally, often yields a larger deduction for filers with higher housing costs. Only self-employed individuals qualify; employees working from home cannot claim the home office deduction under current law.

Charitable Contribution Deductions: Rules and Limits for 2025

Cash donations to qualifying 501(c)(3) organizations remain deductible up to 60% of AGI for itemizers. Non-cash property donations follow a 30% of AGI limit in most cases. Donations of appreciated securities directly to charity — bypassing capital gains tax entirely — remain one of the most tax-efficient giving strategies available.

Qualified Charitable Distributions (QCDs) from IRAs continue to allow taxpayers age 70½ or older to donate up to $105,000 directly from an IRA to a qualifying charity in 2025, excluding that amount from taxable income entirely. This is especially powerful for retirees who don't itemize but want tax benefit from their charitable giving.

See the IRS guidance on charitable contribution deductions for documentation requirements, especially for non-cash gifts over $500 (Form 8283 required).

Frequently Asked Questions About 2025 Tax Deductions

Has the standard deduction increased enough in 2025 to affect my filing strategy?

The increase is modest — roughly $400 to $800 depending on filing status. For most taxpayers already taking the standard deduction, it won't change their strategy, but it does mean a slightly lower tax bill without any extra effort. If you were borderline on itemizing in 2024, revisit that math for 2025 since the higher standard deduction threshold may now surpass your itemized total.

Is the QBI deduction going away after 2025?

The 20% qualified business income deduction is currently set to expire at the end of 2025 along with other TCJA provisions. Whether Congress extends, modifies, or allows it to expire is an open legislative question. If you're a self-employed filer or small business owner, planning around a potential loss of this deduction in 2026 is a conversation worth having now — not after filing season opens.

Can I deduct home office expenses if I'm a remote employee in 2025?

No. Under current law, W-2 employees cannot deduct home office expenses on their federal return, even if they work from home full time. This restriction was established by the TCJA and remains in effect for 2025. Only self-employed individuals — sole proprietors, freelancers, and independent contractors — may claim the home office deduction on Schedule C. Some states have their own rules that differ from the federal standard, so check your state's guidance separately.

What documentation do I need to claim charitable deductions in 2025?

For cash donations under $250, a bank record or written receipt from the organization suffices. For donations of $250 or more, you need a written acknowledgment from the charity. Non-cash donations over $500 require Form 8283, and donations of property valued over $5,000 generally require a qualified appraisal. Keeping thorough records throughout the year is far easier than reconstructing them at tax time.
