Actionable Tips:

  • Justify pricing decisions with market data
  • Compare family member salaries to industry standards

  • Consult tax professionals for compliance reviews

Business Purpose Doctrine

Every Expense Needs a Legitimate Reason

The Rule: Expenses must serve a legitimate business purpose, not personal interests.

Practical Example:

Business Conference Travel ✓

  • Keep event agenda and registration
  • Document participation and networking
  • Save receipts for all related expenses
  • Note business outcomes and contacts made

Thorough documentation strengthens deductions and reduces audit risks.

Substance Over Form Doctrine

Reality Trumps Labels

The IRS examines the economic reality of transactions, not just how they're labeled.

✗ Won't Work

  • Personal vacation labeled as "business trip"
  • Personal vehicle expenses claimed as 100% business
  • Family gifts disguised as salaries

✓ Will Work

  • Genuine business travel with documentation
  • Accurate business-use percentage
  • Fair market compensation for work performed

Regularly review expenses to ensure they align with this principle.
