Guessing your business mileage at tax time is an easy way to trigger an IRS audit.
A lot of business owners assume a rough estimate on their tax return will slide by quietly. In reality, the IRS expects an exact record showing the date, business purpose, and mileage for every single work trip you claim. If you cannot back up those numbers with a real log, they can toss out your entire deduction and hand you a penalty.
Taking five seconds to log each trip saves thousands of dollars in deductions you actually earned.
Do you use an automated mileage app to track your work trips, or are you still relying on paper receipts and memory? Drop your method in the comments.
