2024-2025 Special Per Diem Rates Released, Notice 2024-68

The IRS has released the 2024-2025 special per diem rates. Taxpayers use the per diem rates to substantiate certain expenses incurred while traveling away from home. These special per diem rates include:

1. the special transportation industry meal and incidental expenses (M&IE) rates,
2. the rate for the incidental expenses only deduction,
3. and the rates and list of high-cost localities for purposes of the high-low substantiation method.

Transportation Industry Special Per Diem Rates

The special M&IE rates for taxpayers in the transportation industry are:

• $80 for any locality of travel in the continental United States (CONUS), and
• $86 for any locality of travel outside the continental United States (OCONUS).

Incidental Expenses Only Rate

The rate is $5 per day for any CONUS or OCONUS travel for the incidental expenses only deduction.

High-Low Substantiation Method

For purposes of the high-low substantiation method, the 2024-2025 special per diem rates are:

• $319 for travel to any high-cost locality, and
• $225 for travel to any other locality within CONUS.

The amount treated as paid for meals is:

• $86 for travel to any high-cost locality, and
• $74 for travel to any other locality within CONUS.

Instead of the meal and incidental expenses only substantiation method, taxpayers may use:

• $86 for travel to any high-cost locality, and
• $74 for travel to any other locality within CONUS.

Taxpayers using the high-low method must comply with Rev. Proc. 2019-48, I.R.B. 2019-51, 1392. That procedure provides the rules for using a per diem rate to substantiate the amount of ordinary and necessary business expenses paid or incurred while traveling away from home.

Notice 2023-68, I.R.B. 2023-41 is superseded.
