Per Diem Rates for Lodging, Meals, and Incidentals

Your Hawaii per diem allowance is split into two parts: Lodging and everything else. The second part is called M&IE, which stands for Meals & Incidental Expenses. M&IE is your fixed daily budget for food, drinks, and small cash tips.

U.S. Government Hotel Per Diem Rate in Oahu, Hawaii

Factors affecting per diem rates include the island you are traveling to: Oahu, Hawaii, Kauai, Maui, Lanai, or any of the outlying Hawaii islands. Within each island, the lodging rate will vary depending on the city or the Hawaii Military Base where the traveler is assigned.

Why the Rate for Oahu Is Higher Than for the Big Island: Understanding Locality

You might assume that a work trip to Hawaii has one standard per diem rate, but that’s not the case. The daily allowance for a trip to bustling Honolulu on Oahu is almost always higher than for a trip to the quieter town of Hilo on the Big Island.

GSA Sets Per Diem Rates

The General Services Administration (GSA) is an independent agency of the United States Government that helps manage and support the functioning of all federal agencies. The GSA prescribes travel per diem rates for the Continental U.S. (CONUS).

State Department Per Diem Rates for OCONUS

The Department of State (State Department) prescribes per diem rates for all foreign overseas locations outside the Continental United States (CONUS). The State Department updates these travel rates at the beginning of every month. If any uniformed military members or DoD federal civilians have questions regarding the adequacy of foreign per diem rates, they should contact the Department of State Office of Allowances.

DTMO Sets the Hawaii Per Diem Rates (not GSA)

The Defense Travel Management Office (DTMO) under the auspices of the Department of Defense prescribes per diem rates for Overseas Non-Foreign areas and all official U.S. Territories (including Alaska, Hawaii, Guam, Puerto Rico, etc.).

Federal Per Diem Rate Increases and Decreases

DTMO publishes revised per diem rates in the Federal Register via a Civilian Personnel Per Diem Bulletin. DTMO updates Overseas Non-Foreign Per Diem Travel Rates at least once a year. The Per Diem Committee adds DoD unique footnotes, DoD Installations, and proportional meal rates to rates published by DoS, GSA, and DTMO.

GSA & DTMO Per Diem Rate Audits

This difference comes down to a simple, real-world principle: it costs more to stay and eat in some places than in others.

The U.S. General Services Administration, or DTMO in the case of overseas non-foreign areas, sets these rates and conducts surveys of local market prices. They look at the average cost of hotel rooms and restaurant meals in specific counties to determine a fair rate for that exact area.

Per Diem Rate Changes in Honolulu, Hawaii

Because Hawaii is a destination outside the lower 48 states, it receives this detailed, location-by-location attention to ensure the rates accurately reflect travel costs. To budget correctly, you can’t use a generic “Hawaii rate.” You must find the official rate for the specific island and county you’re visiting.

Hawaii Per Diem Rate Reimbursement – Is it Use or Lose?

Lodging expenses are reimbursable up to the maximum authorized rate. Still, a traveler is not entitled to “pocket the difference” if they can find a hotel, extended stay, or furnished apartment that is less than per diem… It’s use or lose. Because of this, most travelers search for lodging as close as possible to the maximum allowable per diem lodging rate, “Max Lodging Rate,” to take advantage of accommodations with better amenities.

Tips for Managing TDY Travel Expenses

Budgeting for Your Stay – Lodging is reimbursed based on your actual expenses. Meals are paid at a flat rate (you can pocket the difference)

The Per Diem Meals rate for government travelers is paid at a flat reimbursement rate regardless of how much is spent on meals, so unlike lodging, a traveler can pocket the difference if spending less than the authorized meals rate.

Per Diem Rate = Max Lodging + Meals (Local Meals, Proportional, or Government) + Incidental Rate (Local or on Base)

Meals & Incidentals (M&IE) Breakdown: See the descriptions below regarding federal employee travel:

• M&IE Total – the full daily amount received for a single calendar day of travel when that day is neither the first nor last day of travel.
• Breakfast, lunch, dinner, and incidentals – Separate amounts for meals and incidentals. M&IE Total = Breakfast + Lunch + Dinner + Incidentals. Sometimes, a traveler must deduct meal amounts from the trip voucher.
• First & last day of travel – the amount received on the first and last day of travel equals 75% of the total M&IE.

Don’t Get Short-Changed: The 75% Rule for Your First and Last Travel Days.

The government pays the lodging cost and your meal allowance for a standard day. But what about the days you’re flying in and out? Those aren’t full days, and the reimbursement rules are slightly different.

Travel Day Calculation: Your M&IE allowance is calculated differently on the days you fly. Per the official first- and last-day-of-travel per diem rules, you receive 75% of the standard daily M&IE rate. This 75% applies to both the day you arrive in Hawaii and the day you depart, accounting for time spent in transit when your meal options are limited.

The logic is simple: you likely won’t need a full day’s worth of meals while you’re on a plane. This breakdown ensures fairness. For instance, if the M&IE rate in Honolulu is $XYZ, your allowance for your arrival and departure days would each be ($XYZ x 0.75).

Lodging Rate is not affected…only M&IE: Your lodging allowance is not affected; you are still covered for the full cost of your hotel on those nights, up to the maximum rate for your location.

Understanding this distinction is key to building an accurate travel budget and avoiding any surprises.
