Your federal income tax return uses one of two deductions: the standard deduction or itemized deductions. You cannot claim both on the same return. Pick the larger allowable amount after you apply the rules for your filing status and what you can document.
2026 Standard Deduction Amounts
For tax year 2026, the IRS lists these federal standard deduction amounts:
- Single or married filing separately: $16,100
- Married filing jointly or qualifying surviving spouse: $32,200
- Head of household: $24,150
These amounts apply to 2026 federal returns, which you generally file in 2027. A taxpayer who is 65 or older or blind may qualify for an additional standard deduction. The One, Big, Beautiful Bill Act also created a separate temporary senior deduction for eligible taxpayers age 65 and older for tax years 2025 through 2028. That provision has its own eligibility and income limits. Do not assume every older taxpayer gets the same increase.
What Counts As An Itemized Deduction
Itemizing means reporting eligible expenses on Schedule A instead of taking the standard deduction. Depending on your facts, Schedule A may include:
- Medical and dental expenses allowed after the applicable AGI threshold
- State and local income or sales taxes, real estate taxes, and certain personal property taxes, subject to the federal SALT limit and any phaseout
- Home mortgage interest within the applicable acquisition-debt and other limits
- Qualifying charitable contributions with the required records
- Certain casualty losses tied to federally declared disasters
Not every expense tied to a home, investment, or business belongs on Schedule A. Separate rules may apply to business, rental, or investment activity.
How To Compare The Options
Start with the standard deduction for your filing status. Then total only the itemized deductions you can substantiate, and apply the limits that fit your return. If the allowable itemized total is higher, itemizing may reduce taxable income more. If it is lower, the standard deduction is usually the cleaner result.
A larger deduction is not a dollar-for-dollar tax cut. Your marginal tax rate, credits, filing status, and other income and adjustments affect the final tax. A projection using your actual documents beats a generic example.
California And SALT Need Separate Review
The federal SALT rules changed under the One, Big, Beautiful Bill Act. The limit and related phaseout can depend on filing status and income. Do not assume every state and local tax payment is deductible on your federal return.
California runs its own state calculation and does not conform to every federal change. You may itemize federally and use a different deduction method on your California return, or the reverse. Review current IRS guidance and California Franchise Tax Board instructions for the year you are filing.
Records And Timing Matter
Keep mortgage interest statements, property-tax bills, state-tax payment records, charitable acknowledgments, and support for eligible medical expenses. For noncash gifts, keep the documentation required for the type and value of the property. Charitable bunching may be worth modeling when donations sit near the standard-deduction amount. Model genuine gifts with complete records, not a tax result manufactured on paper.
A Practical Decision Checklist
- Confirm your 2026 filing status and base standard deduction.
- Gather Schedule A records and remove expenses that are not allowable.
- Apply federal limits, including the rules for SALT and mortgage interest.
- Compare federal and California results separately.
- Recheck the calculation if your income, age, charitable giving, or property situation changes.
If the two methods are close, or your return includes substantial property taxes, mortgage interest, charitable gifts, or investment activity, a CPA can compare the choices using your facts. Schedule a complimentary consultation with LaviCPA.
