IRS deduction option: Instead of tracking actual costs, you can deduct $0.67/mile for 25,000 business miles = $16,750 deduction. Compare to your actual costs of $15,442 to choose the better method.
Why track true per-mile cost?
The IRS standard mileage rate ($0.67 for 2024) is a simplified deduction that may not reflect your actual costs. High-mileage gig workers and delivery drivers often exceed this rate when depreciation and maintenance are factored in. Tracking actual costs lets you compare the standard deduction vs. actual expense method on your Schedule C — choose whichever gives you the larger deduction. Keep a mileage log for documentation.
