What deductions raise red flags?


Editorial team Published on

Certain tax deductions raise red flags with the IRS when they are disproportionate to your income or deviate from statistical norms.

🚗 Vehicle & Travel Deductions

  • Claiming 100% business use for a single vehicle without maintaining a detailed mileage log.
  • Writing off personal vacations or standard commuting miles as business travel.
  • Deducting unusually high business meal expenses without a documented business purpose or receipt.

🏠 Home Office & Personal Expenses

  • Claiming a home office deduction as a W-2 employee rather than a self-employed individual.
  • Exceeding reasonable square footage calculations or failing the exclusive business-use test.
  • Mixing personal lifestyle or family costs into business write-offs.

📉 Business Losses & Hobbies

  • Reporting consecutive business losses (e.g., 3 to 5 years) on a Schedule C without showing a true profit motive.
  • Deducting expenses for a personal activity or hobby—such as horse breeding, crafting, or photography—as a commercial enterprise.

🎁 Charitable Donations

  • Claiming outsized charitable gifts that are disproportionately large relative to your total reported adjusted gross income.
  • Failing to attach mandatory documentation or appraisals for non-cash contributions exceeding specific dollar thresholds.
