Are Provided Meals Deducted From Your Per Diem?

Per diem is meant to cover meals and small daily costs once, not twice. So GSA built a straightforward rule: if a meal is handed to you free of charge, you deduct that meal's value from your day's Meals and Incidental Expenses (M&IE) allowance before you claim it. Below is exactly how much to subtract, what counts as 'provided', and where the line sits.

How the meal-by-meal deduction works

GSA doesn't just publish one M&IE number for each location. Every tier is split into set amounts for breakfast, lunch, dinner and incidentals, listed in the GSA per diem rates tables. When a meal is provided, you find your trip's daily tier, look up the amount allocated to that specific meal, and subtract only that figure. You don't estimate a third of the total, and you don't touch the other two meals or the incidentals portion. This mechanic comes from the Federal Travel Regulation that GSA per diem is built on.

GSA M&IE meal breakdown table (FY2026)

Worked example: a conference lunch

Say you're on a $68 standard-tier trip and your conference registration includes lunch. Use the breakdown, not the full daily rate.

• Full M&IE for the day: $68
• Lunch provided free of charge: subtract $19
• Remaining M&IE you can claim: $68 − $19 = $49
• That $49 still includes the full $5 incidentals allowance, untouched

If dinner had also been provided that same day, you'd subtract the $28 dinner figure too: $68 − $19 − $28 = $21, still carrying the full $5 for incidentals inside it.

The $5 incidentals allowance is never deducted

Even if all three meals are free that day, you still keep the incidentals portion. On the standard tier, deducting breakfast, lunch and dinner is $16 + $19 + $28 = $63, leaving exactly $5 — your untouched incidentals allowance. This is a built-in safeguard: meal deductions can reduce your M&IE claim right down to the incidentals figure, but never below it.

What actually counts as a 'provided' meal

Not every free bite of food triggers a deduction. The test is simple: was the meal furnished to you directly, at no separate cost, with no real option to skip it and buy your own instead?

• Deduct it: lunch built into your conference or event registration fee
• Deduct it: a dinner your client, host or employer pays for on your behalf
• Deduct it: a meal supplied directly at a training course or work site
• Don't deduct it: a complimentary continental breakfast that comes standard with your hotel room, offered to every guest regardless of your trip
• Don't deduct it: a meal served on a flight or by another common carrier
• Don't deduct it: a cash per-meal stipend or allowance — you still paid for your own food, so nothing was actually furnished to you

GSA states the hotel and airline exception directly on its own M&IE breakdown guidance. The deduction rule targets meals someone specifically arranged and paid for as part of your trip, not routine extras that already come with the room or the ticket.

“Meals provided by a common carrier or a complimentary meal provided by a hotel/motel do not affect per diem.”

Don't forget the first and last day

Travel days work differently. On your departure day and your return day, you only claim 75% of the full M&IE rate to start with — see the first-and-last-day 75% rule for the full mechanics. If a meal is provided on one of those days, subtract the meal's full breakdown amount from the already-reduced 75% figure, not from the full daily rate.

Working this out by hand across a multi-day trip with a mix of provided and paid meals gets fiddly fast. PerDiemWise's meals and incidentals calculator does the meal-by-meal maths for you — pick your tier, mark which meals were provided, and it returns the exact amount left to claim.
