Schedule C expense categories, line by line

Schedule C is where sole proprietors and single-member LLCs report business income and expenses. Putting expenses on the right lines keeps your return clean and your numbers easy to defend.

Updated · General information, not tax advice

Key takeaways

  • Part II has expense lines 8 through 27b. Anything without its own line goes in Part V, Other expenses, which carries to line 27b.
  • Car expenses go on line 9, with details in Part IV or on Form 4562.
  • Meals go on line 24b at the deductible amount, which is usually 50%.
  • The home office deduction goes on line 30, not in Part II.

Lines people often get wrong

  • Other expenses on 27a. On the current form, other expenses itemized in Part V carry to line 27b; 27a is the energy efficient commercial buildings deduction.
  • Health insurance on line 15. Self-employed health insurance is usually deducted on Schedule 1, not Schedule C.
  • Paying yourself as wages. Owner draws aren’t wages and aren’t deductible.
  • Meals at 100%. Most business meals are 50% deductible, and entertainment isn’t deductible.
  • Gas plus mileage. With the standard mileage rate, fuel and repairs are already included. See the 2026 mileage rate.

Line 30: business use of your home

The home office deduction has its own line. Use the simplified method ($5 per square foot, up to 300 square feet) or Form 8829 for actual expenses. Our home office guide walks through both.
