Itemized Deductions Explained for 2026
One of the most important tax decisions you’ll make each year is whether to claim the standard deduction or itemize your deductions.
For the 2026 tax year, itemizing only makes sense if your total allowable deductions exceed your standard deduction after applying all IRS limits and phase-down rules.
While many taxpayers benefit from the increased standard deduction, homeowners, charitable donors, and taxpayers with significant medical expenses may still save more by itemizing.
Here’s what you need to know about itemized deductions in 2026.
What Are Itemized Deductions?
Itemized deductions are eligible personal expenses that the IRS allows you to subtract from your taxable income instead of claiming the standard deduction.
Each year, taxpayers can choose whichever deduction provides the greater tax benefit:
- Claim the standard deduction, or
- Elect to itemize deductions on their federal tax return.
If your allowable itemized deductions exceed your standard deduction, itemizing will generally reduce your taxable income and lower your federal tax bill.
2026 Standard Deduction Amounts
Before deciding whether to itemize, compare your deductions to the 2026 standard deduction:
- Single: $16,100
- Married Filing Separately: $16,100
- Head of Household: $24,150
- Married Filing Jointly: $32,200
- Qualifying Surviving Spouse: $32,200
If your total allowable itemized deductions are greater than these amounts, itemizing may provide greater tax savings.
Common Itemized Deductions in 2026
The most frequently claimed itemized deductions include:
- State and local taxes (SALT)
- Qualified mortgage interest
- Medical and dental expenses
- Charitable contributions
- Qualified casualty and disaster losses
These deductions are subject to specific IRS rules and limitations.
2026 SALT Deduction Limit
The deduction for state and local income, sales, and property taxes is limited to:
- $40,400 for most taxpayers
- $20,200 for Married Filing Separately
For higher-income taxpayers, the deduction begins to phase down when modified adjusted gross income exceeds:
- $505,000 for most filers
- $252,500 for Married Filing Separately
The deduction generally cannot be reduced below:
- $10,000 for most taxpayers
- $5,000 for Married Filing Separately
Medical Expense Deduction
Medical and dental expenses are deductible only to the extent they exceed 7.5% of your adjusted gross income (AGI).
This means only the portion above the 7.5% threshold qualifies as an itemized deduction.
Charitable Contribution Rules
Beginning in 2026, taxpayers who itemize may generally deduct charitable contributions only to the extent they exceed 0.5% of AGI, subject to the applicable IRS percentage limitations.
Depending on the type of contribution and the organization receiving the donation, different AGI limits may apply.
Mortgage Interest Deduction
Homeowners may generally deduct qualified mortgage interest on acquisition debt.
For mortgages incurred after December 15, 2017, the deduction is generally limited to interest on up to:
- $750,000 of qualified acquisition debt
- $375,000 if Married Filing Separately
For 2026, qualifying mortgage insurance premiums are also treated as deductible mortgage interest under current tax law.
Casualty Loss Deductions
Personal casualty losses are generally deductible only if they result from a federally declared or qualifying state-declared disaster.
The deductible loss is generally reduced by:
- $100 per casualty event, and
- 10% of your adjusted gross income.
High-Income Limitation on Itemized Deductions
Beginning in 2026, certain higher-income taxpayers may see their itemized deductions reduced.
The limitation generally applies when taxable income exceeds:
- $768,700 – Married Filing Jointly or Qualifying Surviving Spouse
- $640,600 – Single or Head of Household
- $384,350 – Married Filing Separately
Once these thresholds are exceeded, allowable itemized deductions may be reduced under the applicable IRS calculation.
Who Cannot Claim the Standard Deduction?
Some taxpayers generally cannot use the standard deduction, including:
- Married Filing Separately taxpayers whose spouse itemizes deductions
- Certain nonresident aliens
- Estates and trusts
- Certain short-period tax returns
In these situations, itemizing may be required.
You May Still Qualify for Other Deductions
Even if you choose the standard deduction, you may still qualify for several deductions outside of itemized deductions, including:
- Qualified Business Income (QBI) Deduction
- Qualified Tips Deduction
- Qualified Overtime Deduction
- Charitable deduction available to non-itemizers (subject to annual limits)
These deductions can further reduce your taxable income even if you do not itemize.
Final Thoughts
Itemized deductions remain an important tax-saving opportunity in 2026, but they are subject to several IRS limitations, including the higher SALT cap, the 7.5% medical expense threshold, the new charitable contribution floor, and the return of the high-income limitation on itemized deductions.
For many taxpayers, the increased standard deduction will still provide the greatest benefit. However, homeowners, generous charitable donors, and taxpayers with significant deductible expenses should compare both options before filing.
Choosing the right deduction can significantly reduce your taxable income and help you avoid paying more tax than necessary.
