For tax professionals who work with sole proprietors, freelancers, and independent contractors, Schedule C is a familiar—but often misunderstood form. Used to report profit or loss from a business, Schedule C can be deceptively complex. With continued IRS scrutiny on self-employed returns and evolving compliance standards, tax preparers must be more diligent than ever.
We'll review the latest 2024 Schedule C updates, highlight frequent preparer pitfalls, and share best practices to keep your clients compliant and your work airtight.
Understanding Schedule C
Schedule C (Form 1040), Profit or Loss From Business, is used by:
- Sole proprietors
- Single-member LLCs not electing corporate taxation
- Statutory employees
- Gig workers and freelancers
- Spouses in qualified joint ventures
It's also applicable for reporting income from Forms 1099-NEC, 1099-MISC, and 1099-K.
2025 IRS Mileage Rates
The IRS has announced the standard mileage rates for 2025:
- Business use: 70 cents per mile
- Medical and moving purposes: 21 cents per mile
- Charitable organizations: 14 cents per mile
These rates apply to electric, hybrid, gasoline, and diesel-powered vehicles.
Common Mistakes to Avoid When Preparing Schedule C
Even seasoned tax preparers should be vigilant about:
- Underreporting Income: Ensure all income, including digital payments and cash transactions, is accurately reported.
- Home Office Deductions: Use Form 8829 or the simplified method appropriately, and maintain proper documentation.
- Vehicle Expenses: Choose between the standard mileage rate and the actual expenses method, and apply it consistently.
- Material Participation: Correctly assess and document the taxpayer's involvement to determine passive or active status.
