What Is Schedule A?

Schedule A reports allowable itemized deductions subject to category-specific rules and limits.

Reviewed August 2026 · Mint Associates Ltd Co · Houston, Texas

How it works

The rule, and what it turns on.

Common categories include medical expenses, certain taxes, mortgage interest, charitable contributions and other permitted items.

Example

Large mortgage interest and charitable contributions can make itemizing better than the standard deduction.

Common mistakes

What we see go wrong, and what we do instead.

  • Treating personal expenses as itemized deductions.
  • Poor charitable substantiation.

A better approach

  • Compare total allowable itemized deductions with standard deduction annually.

Authority

Where this comes from, so you can check it.

IRC §§63(d), 164, 165, 170, 213 and 163(h), as applicable; Schedule A instructions.
