Are employees at your business traveling and frustrated about documenting expenses? Or perhaps you’re annoyed at the time and energy that goes into reviewing business travel expenses.

There may be a way to simplify the reimbursement of these expenses.

In Notice 2023-68, the IRS announced the fiscal 2024 special per diem rates that became effective Oct. 1, 2023.

Taxpayers can use these rates to substantiate the amount of expenses for lodging, meals and incidentals when traveling away from home. (Taxpayers in the transportation industry can use a special transportation industry rate.)

Basics

A simplified alternative to tracking actual business travel expenses is to use the “high-low” per diem method.

This method provides fixed travel per diems. The amounts, provided by the IRS, vary from locality to locality.

Under the high-low method, the IRS establishes an annual flat rate for certain areas with higher costs of living.

All locations within the continental U.S. that aren’t listed as high-cost are automatically considered low-cost.

All locations within the continental U.S. that aren’t listed as high-cost are automatically considered low-cost.

The high-low method may be used in lieu of the specific per diem rates for business destinations.

Examples of high-cost areas include Boston, and San Francisco. Other locations, such as resort areas, are only considered high-cost during part of the year.

Under some circumstances—for example, if an employer provides lodging or pays the hotel directly—employees may receive a per diem reimbursement only for their meals and incidental expenses.

There’s also a $5 incidental-expenses-only rate for employees who don’t pay or incur meal expenses for a calendar day (or partial day) of travel.

Reduced Recordkeeping

If your company uses per diem rates, employees don’t have to meet the usual recordkeeping rules required by the IRS.

Receipts of expenses generally aren’t required under the per diem method.

But employees still must substantiate the time, place and business purpose of the travel.

Per diem reimbursements generally aren’t subject to income or payroll tax withholding or reported on an employee’s Form W-2.

Fiscal 2024

For travel after Sept. 30, 2023, the per diem rate for all high-cost areas within the continental U.S. is $309. This consists of $235 for lodging and $74 for meals and incidental expenses.

For all other areas within the continental U.S., the per diem rate is $214 for travel after Sept. 30, 2023 ($150 for lodging and $64 for meals and incidental expenses).

Compared to fiscal 2023 per diems, the high-cost area per diem increased $12, and the low-cost area per diem increased $10.

Important: This method is subject to various rules and restrictions. For example, companies that use the high-low method for an employee must continue using it for all reimbursement of business travel expenses within the continental U.S. during the calendar year.

Note that per diem rates can’t be paid to individuals who own 10% or more of the business.

However, the company may use any permissible method to reimburse that employee for any travel outside the continental U.S.

For travel during the last three months of a calendar year, employers must continue to use the same method (per diem or high-low method) for an employee as they used during the first nine months of the calendar year.

Also, note that per diem rates can’t be paid to individuals who own 10% or more of the business.

If your employees are traveling, it may be a good time to review the rates and consider switching to the high-low method.

It can reduce the time and frustration associated with traditional travel reimbursement.
