What is the per diem rate for Iran?

For Tehran the maximum is $155 a day: up to $97 for lodging, plus $58 for meals and incidental expenses. Other locations in the country have their own rates, listed in the table above.

Who sets these rates, and who uses them?

The US Department of State sets per diem rates for every foreign location and revises them monthly. They are binding for US government civilian travel, and many companies, universities and contractors adopt them as their own travel policy limits.

What does the meals and incidentals rate cover?

Breakfast, lunch, dinner and small incidental costs such as tips and laundry. When a meal is provided, the State Department deducts a fixed share: 15% for breakfast, 25% for lunch and 40% for dinner, leaving 20% for incidentals.

Is the lodging rate what a hotel actually costs?

No. It is a ceiling, set from the price of hotels suitable for official travel in that location, and actual costs are reimbursed up to it. A traveler choosing their own hotel will often pay less.
