Q: Can I use the per diem if I'm self-employed?

Yes, for meals. The IRS lets self-employed people use the government meal rate instead of adding up meal receipts, and you write off half of it. For the hotel, you write off what you paid and keep the receipt.

For trips from October 1, 2026, through September 30, 2027, the per diem in most of Montana is $113 a night for a hotel and $68 a day for meals. The per diem is higher in 4 Montana cities, including Big Sky, Kalispell/Whitefish, and Missoula.
