Itemize or Standard Deduction in 2026? Free Calculator Shows Which Saves More

Should You Itemize or Take the Standard Deduction in 2026?

The OBBB Act (P.L. 119-21, signed July 4, 2025) extended the nearly doubled standard deduction that TCJA introduced. For 2026, the standard deduction is approximately:

  • Single: $15,000
  • Married Filing Jointly: $30,000
  • Head of Household: $22,500

With the $10,000 SALT cap also extended by OBBB, fewer taxpayers benefit from itemizing than pre-2018. But if you have a large mortgage, live in a high-tax state, or give generously to charity, itemizing could still save you thousands.

The Calculator Does the Math

Our Itemize vs Standard Deduction Calculator takes your actual numbers and gives a clear recommendation:

  • Mortgage interest — enter your annual interest paid
  • SALT — state and local taxes (auto-capped at $10,000)
  • Charitable donations — cash and non-cash contributions
  • Medical expenses — only the amount above 7.5% of your AGI counts
  • Other deductions — casualty losses, investment expenses, etc.

The result: a side-by-side comparison showing exactly how much you save (or lose) by itemizing vs. taking the standard deduction.

Who Should Itemize in 2026?

Three scenarios where itemizing still wins: 1. Homeowners with mortgages above $300K at 6%+ rates — annual interest alone can exceed $18,000 2. Residents of high-SALT states (CA, NY, NJ, CT, IL) — even capped at $10K, combined with mortgage interest it pushes past standard deduction 3. Generous charitable givers — donating 5%+ of income, especially with appreciated stock

For everyone else, the standard deduction is almost certainly larger. Source: IRS, Congress.gov P.L. 119-21.
