Don’t Risk Income Tax on your Travel Expenses: Business Expense Substantiation

If you travel for work, now is the time to familiarize yourself with the revised Business Expense Substantiation & Tax Implications procedures. Effective January 1, 2023, requirements for timely substantiation/submission of business expenses apply to Travel Card and Airfare Card transactions, as well as to employee out-of-pocket reimbursements.

Beginning 1/1/23, if you do not document, attach receipts, and submit your trip expenses – including Airfare Card transactions (flights booked in Concur/CBT), Travel Card transactions, and out-of-pocket (personally paid) expenses – on an expense report in Concur within 90 days of the end of the trip, the full amount of the trip expenses will be reported as taxable income to you.

How to Prepare:

  • Review any unsubmitted Airfare Card and Travel Card transactions in Concur now. The PSC sends monthly notifications regarding unsubmitted Airfare Card and Travel Card expenses older than 30 days. These emails go out on the 15th of the month.
  • For any unsubmitted expenses related to a trip that ended on or before October 1, 2022: assign the Airfare Card/Travel Card transactions to a Travel Reimbursement expense report, add any relevant out-of-pocket expenses (e.g., per diem), enter the required business purpose and attach required receipts, and submit the report in Concur immediately. These transactions will otherwise be more than 90 days past the trip end date as of January 1, 2023, and the traveler/cardholder could incur a tax liability.
