Per Diem Update for 2023-2024

If you travel for your job, you probably have to deal with per diem rates or the amounts that you can deduct for your travel expenses.  Here are the latest rates for the next federal fiscal year:

The IRS issued Notice 2023-68, an annual notice providing updated special per diem rate information for the federal fiscal year starting October 1, 2023. Because employees may not claim itemized deductions for unreimbursed business expenses, including travel expenses, per diem rate information applies only to self-employed taxpayers and to employers’ accountable plans and other travel guidelines. The only changes this year are slight increases in the overall high-low travel rates.

Special per diem rates

Special per diem rates apply to the following:

  1. Transportation industry rates. The special meal and incidental expense (M&IE) rates for the transportation industry are $69 for the continental United States (CONUS) and $74 outside the continental United States (OCONUS).
  2. Incidental expense rate. The rate for the incidental expense only deduction is $5 for CONUS and OCONUS.
  3. High-low substantiation method rates. The per diem rates are $309 for travel to high-cost localities and $214 for travel to other localities. The meals and incidental expense (M&IE) portion of the high-low rates is $74 for high-cost localities and $64 for other localities. The notice includes a list of high-cost localities for purposes of this method.

Regular per diem rates

For regular per diem information see GSA’s per diem rates

Incidental expenses

Rev. Proc. 2019-48 states that for tax purposes the term incidental expense has the same meaning as that used in the Federal Travel Regulations issued by the General Services Administration (GSA). These regulations provide that incidental expenses include only “fees and tips given to porters, baggage carriers, bellhops, hotel staff, and staff on ships.” Other types of miscellaneous expenses may be deductible but require substantiation of the actual expense.

Lodging expenses

There is no standard lodging allowance.

  • Employers use the lodging rates to determine the maximum travel allowance that may be provided tax-free to employees under an accountable plan. 
  • Self-employed taxpayers must use actual lodging expenses to calculate their lodging deduction.
