Itemized Deductions in 2026: What Individuals Need To Know Before They File
Itemized deductions remain highly relevant in 2026, but their value depends on whether total deductible amounts exceed the standard deduction and whether specific statutory caps or floors apply. For individuals, the most significant itemized deduction categories commonly include state and local taxes, home mortgage interest, charitable contributions, casualty losses in limited cases, and certain medical expenses. The key is not just knowing what is deductible, but understanding the limits and substantiation rules that govern each category .
One major development is the increased limitation on the deduction for state and local taxes. For 2025, the overall limit on the deduction for state and local income, sales, and property taxes increased to $40,000, or $20,000 for married filing separately. That limit is reduced for taxpayers with modified adjusted gross income above $500,000, or $250,000 for married filing separately, but not below $10,000, or $5,000 for married filing separately . This matters both for direct Schedule A planning and for taxpayers allocating taxes between personal and business or rental use of a residence .
Medical expenses remain deductible only to the extent they exceed the applicable AGI floor under Schedule A rules, so taxpayers should preserve invoices, proof of payment, and insurance reimbursement records. Mortgage interest remains deductible only within the statutory home mortgage interest framework, and taxpayers using part of a residence for business must coordinate the personal Schedule A deduction with any business-use allocation .
Charitable contributions require careful substantiation. Cash and noncash gifts have different documentation standards, and inventory donations by sole proprietors are subject to basis-based limitations rather than simple fair market value treatment in many cases .
Casualty losses are now generally limited, and for many taxpayers only federally declared disaster losses produce a deductible itemized deduction effect. Taxpayers using a home partly for business must separately track the personal and business portions of casualty losses .
The practical filing question is whether itemizing produces a larger deduction than the standard deduction. Taxpayers should total capped SALT deductions, allowable mortgage interest, charitable contributions, and any other permitted itemized deductions before deciding. Good records remain essential because the IRS expects taxpayers to support each claimed amount if questioned .
In short, itemized deductions can still produce meaningful tax savings, but only if the taxpayer understands the category-specific limits and keeps records sufficient to support the deduction claimed .
