Misclassified transport and fuel expenses are one of the most common triggers for IRS scrutiny of small business returns.
Most business owners do not know this until they are already in a review.
The IRS requires that every vehicle and transportation deduction be supported by four things: the date of the trip, the destination, the business purpose, and the mileage. Without all four, that deduction is at risk. When expenses are recorded but never reviewed, that documentation is frequently absent or inconsistent with what was claimed.
The outcome is a situation where two harmful things happen simultaneously. The business has overspent because no one caught the error while it was occurring, and then the deduction is lost because the paperwork cannot hold up to scrutiny. You are penalized twice: once through the unchecked spending and again through the lost tax benefit.
A consistent bookkeeping review process catches the documentation problem before it becomes an audit problem.
How are you currently tracking your business mileage and transportation expenses? I read every comment.
