Tips & Best Practices

  • The OBBBA raised the SALT cap from $10,000 to $40,400, making itemizing worthwhile for many more homeowners
  • About 90% of taxpayers take the standard deduction — but if you own a home with a mortgage in a high-tax state, itemizing may save thousands
  • Consider bunching charitable contributions: give two years of donations in one year to exceed the standard deduction, then take standard the next year
  • Medical expenses are only deductible above 7.5% of your AGI — most healthy taxpayers get no medical deduction
  • The SALT cap phase-down applies to taxpayers with MAGI above $505,000 (single)

Frequently Asked Questions

Should I take the standard deduction or itemize?

Take the standard deduction if your total itemized deductions are less than the standard deduction for your filing status. Itemize only if your total exceeds the standard deduction. About 90% of taxpayers take the standard deduction.

What is the 2026 standard deduction?

For 2026, the standard deduction is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for head of household. Additional amounts apply if you are 65+ or blind.

What changed with the SALT deduction in 2026?

Under the OBBBA, the SALT cap increased from $10,000 to $40,400 for 2026. However, the cap phases down for high-income taxpayers with MAGI above $505,000 (single) or $252,500 (MFS). The floor is $10,000.

What deductions can I itemize?

Common itemized deductions include: state and local taxes (SALT, capped at $40,400), mortgage interest on up to $750,000 of debt, charitable contributions (up to 60% of AGI for cash), and medical expenses exceeding 7.5% of AGI.

What is deduction bunching?

Deduction bunching means concentrating two years of charitable giving into one year to exceed the standard deduction threshold, then taking the standard deduction in the alternate year. This can save more tax than spreading donations evenly.
