How this calculator works

Per diem = (full days × daily rate) + (partial days × daily rate × 3/4). Deductible amount = per diem × 80%.

Instead of saving every meal receipt, a self-employed driver in the transportation industry can deduct a flat IRS meal and incidental expense (M&IE) rate for each day away from home overnight. There's one rate for travel in the continental US (CONUS) and one for travel outside it (OCONUS), and the IRS sets both each year for the period from October 1 to September 30.

Partial days. The day you leave and the day you get home count at 3/4 of the rate. A trip from Monday to Friday is 3 full days plus 2 partial days, which is 4.5 days of per diem.

The 80% limit. Meals are normally 50% deductible. If you're subject to DOT hours of service rules, as interstate truck drivers are, you deduct 80%.

Which rate applies. Each day uses the rate for its own date, so a trip that runs across October 1 is split between two periods. The newest rate on file is for Oct 1, 2026 – Sep 30, 2027. For travel after that, the calculator shows the days as pending instead of guessing. See every rate by year on the per diem rates page.

Keep a log of each trip: the dates you left and got back, where you went, and the business reason. The flat rate replaces meal receipts, not the travel record.
