Standard Deduction

• Single: $16,100

Enhanced Senior Deduction: Eligible taxpayers age 65 or older may also qualify for an additional $6,000 deduction per person ($12,000 if both spouses qualify). Income limitations and phaseouts apply.

 

Itemized Deductions

Instead of taking the standard deduction, taxpayers may choose to itemize deductions on Schedule A when their allowable itemized deductions provide a greater tax benefit.
 

Common itemized deductions include:

• Medical & Dental Expenses: Qualified unreimbursed medical and dental expenses may be deductible to the extent they exceed 7.5% of Adjusted Gross Income (AGI).
 

• State & Local Taxes (SALT): Certain state and local income or sales taxes, real estate taxes, and personal property taxes may be deductible, subject to applicable limits and income-based restrictions.
 

• Home Mortgage Interest: Qualified mortgage interest on a primary or second home may be deductible, subject to mortgage and other eligibility requirements.
 

• Charitable Contributions: Contributions to qualified charitable organizations may be deductible, subject to applicable limitations and documentation requirements.
 

• Investment Interest: Interest paid on money borrowed for qualifying investments may be deductible, generally subject to investment-income limitations.
 

• Certain Casualty & Theft Losses: Some qualifying losses may be deductible when applicable requirements are met.
 

2026 Charitable Giving Note: Beginning in 2026, eligible taxpayers who do not itemize may also deduct up to $1,000 of qualifying cash charitable contributions ($2,000 for married couples filing jointly).

Standard vs. Itemized: Generally, taxpayers should compare their allowable itemized deductions with their standard deduction and use the method that provides the greater federal tax benefit.

Deduction eligibility and limitations depend on individual circumstances. Documentation and substantiation requirements may apply.
