Should you take the standard deduction or itemize? This calculator compares both options for your specific situation and tells you which one saves more.

Compare Your Deductions

[CALCULATOR WIDGET PLACEHOLDER]

Enter the following:

Your Information:

  1. Filing status (Single, MFJ, MFS, HoH)
  2. Age (for additional standard deduction if 65+)
  3. Blind? (for additional standard deduction)

Itemized Deductions: 4. Mortgage interest paid 5. State and local income taxes paid 6. Property taxes paid 7. SALT cap status (check current 2026 cap) 8. Charitable cash contributions 9. Charitable non-cash contributions 10. Medical expenses (total) 11. Your AGI (for 7.5% medical threshold) 12. Casualty/theft losses from federal disasters 13. Other itemized deductions

The calculator shows:

  • Your standard deduction amount
  • Your total itemized deductions (with limitations applied)
  • Which option saves more and by how much
  • Estimated tax savings from choosing the better option
  • Whether the bunching strategy could help in future years

2026 Standard Deduction Amounts

Filing StatusStandard Deduction

Married Filing Separately~$15,350

Additional standard deduction:

  • Age 65+ or blind: ~$2,000 (single/HoH) or ~$1,600 (married) per qualifying condition

When Itemizing Typically Makes Sense

You are more likely to benefit from itemizing if you have:

DeductionThreshold to Watch
Mortgage interestSignificant interest on a loan up to $750K
State/local + property taxesAt or near the SALT cap
Charitable contributionsLarge donations (cash or appreciated assets)
Medical expensesExpenses exceeding 7.5% of AGI

Quick Test

Add up your mortgage interest, SALT (up to the cap), and charitable contributions. If the total exceeds your standard deduction, you should likely itemize.

Who Usually Itemizes

  • Homeowners with mortgages in high-tax states
  • Taxpayers who made large charitable donations
  • Individuals with significant medical expenses
  • Those who experienced federally declared disaster losses

Who Usually Takes the Standard

  • Renters
  • Homeowners with small or paid-off mortgages
  • Taxpayers in low-tax states
  • Those without significant charitable contributions

The Bunching Strategy

If you are close to the itemizing threshold but do not quite exceed it, consider bunching deductions into alternating years:

YearStrategyDeduction Claimed
Year 1Bunch: donate 2 years’ worth of charitable gifts, prepay property taxItemize ($28,000)
Year 2Minimal deductible expensesStandard deduction ($15,350)
2-Year Total$43,350

Without bunching, you would take the standard deduction both years ($30,700 total), saving $12,650 less.

Donor-advised funds are ideal for charitable bunching — make a large tax-deductible contribution in one year, then distribute to charities over time.

Itemized Deduction Rules and Limits

SALT Deduction

State and local taxes (income or sales tax + property tax) are subject to a cap. Monitor the 2026 cap status, as the $10,000 TCJA cap may be modified or expire.

Medical Expenses

Only the amount exceeding 7.5% of your AGI is deductible. If your AGI is $80,000, only medical expenses above $6,000 count.

Mortgage Interest

Deductible on up to $750,000 of acquisition debt ($1 million for pre-2018 mortgages). Home equity loan interest is deductible only if used for home improvements.

Charitable Contributions

  • Cash: up to 60% of AGI
  • Appreciated property: up to 30% of AGI
  • Must donate to qualified 501(c)(3) organizations
  • Donations over $250 require written acknowledgment

Key Takeaways

  • About 88–90% of filers take the standard deduction — but that does not mean you should assume it is best for you
  • The quick test: add mortgage interest + SALT (up to cap) + charitable contributions; if it exceeds the standard deduction, itemize
  • The bunching strategy can save thousands over a two-year period for borderline filers
  • Medical expenses must exceed 7.5% of AGI, making them deductible mainly for those with very high costs or lower incomes
  • Regardless of whether you itemize, above-the-line deductions (retirement, HSA, student loan interest) always apply
