How much did you miss?
Three questions. We'll estimate the business-mile deductions you haven't logged, and what a year of logging is worth from here.
How we calculate
Your miles × the IRS rate for each date.
- Weekly business miles × 48 working weeks a year, spread evenly over the months.
- Each day is valued at the IRS business standard mileage rate in effect that day, so mid-year changes count.
- We count back at most 3 years, the usual window to amend a US federal return.
- This estimates what you may have missed. What Backmiles can rebuild depends on your Google Timeline file.
- Not tax advice. The standard mileage deduction applies to business driving for the self-employed and business owners; ask a tax professional about your case.
