How It Works

You can either take the standard deduction (a fixed amount based on filing status) or itemize your deductions (list individual qualifying expenses). You should choose whichever is larger to minimize your taxable income.

Standard Deduction (2026)

  • Single: $15,350
  • MFJ: $30,700
  • MFS: $15,350
  • HOH: $23,100

Common Itemized Deductions

  • Mortgage interest (on loans up to $750k)
  • State and local taxes (capped at $10,000 SALT)
  • Charitable contributions
  • Medical expenses over 7.5% of AGI

Examples

Example 1: Standard is Better

Single filer with $8,000 mortgage interest, $5,000 SALT, $1,000 charity = $14,000 itemized. Standard deduction $15,350 is higher → Take standard.

Example 2: Itemizing is Better

MFJ with $18,000 mortgage interest, $10,000 SALT, $5,000 charity = $33,000 itemized. Standard deduction $30,700 → Itemize for extra $2,300 deduction.
