What is per diem for federal employees?

Per diem is the maximum daily reimbursement a federal employee may receive when traveling on official business (TDY — temporary duty). It has two components: a lodging rate (the actual hotel cap for that destination) and an M&IE (Meals and Incidental Expenses) rate (a flat daily allowance for meals, tips, and minor incidentals). Rates are set by the General Services Administration (GSA) and updated each October for the new fiscal year.

What is the difference between the lodging rate and the M&IE rate?

The lodging rate is a per-night ceiling on hotel reimbursement — if your hotel costs less, you are reimbursed the actual cost; if it costs more, you pay the difference unless your agency grants an exception. The M&IE rate is a flat daily allowance you receive regardless of what you actually spend on meals — it covers breakfast, lunch, dinner, and incidental expenses (tips, laundry, etc.). There are five M&IE tiers in FY2026: $68, $74, $80, $86, and $92/day.

How does the first/last-day rule work?

On your departure day and return day, you receive only 75% of the full M&IE rate (lodging is not prorated — you receive the full nightly rate for the nights you stay). For example, if your M&IE rate is $80, your first and last day each pay $60. There is no GSA regulation requiring you to itemize actual meals on your first/last day — the 75% rate is a fixed allowance.

What if my actual lodging cost exceeds the per diem rate?

You are responsible for the difference. However, your agency can authorize actual expense reimbursement above the per diem rate if lodging at or below the rate is not reasonably available in the area, or for other justified reasons. This requires advance written approval from your approving official and documentation that you made reasonable efforts to find lodging at or below the rate.

How often do GSA per diem rates change and when does FY2026 apply?

GSA updates per diem rates annually for the new fiscal year, which begins October 1. FY2026 rates are effective October 1, 2025 through September 30, 2026. Seasonal rate variations within a fiscal year are published as part of the annual table — so a destination can have different lodging rates in July vs. January within the same fiscal year. This tool reflects the complete FY2026 monthly rate table for each non-standard area.

Highest lodging rates for FY2026

Standard CONUS vs. non-standard areas

The standard CONUS rate ($110 lodging / $68 M&IE) applies to every destination in the continental U.S. not specifically listed as a non-standard area (NSA). The GSA currently designates roughly 300 NSAs — cities or regions where local hotel costs and cost of living justify rates above the standard. This tool covers all NSAs with rates confirmed from the GSA API.

If your destination does not appear in the tool, use the standard CONUS rate. You can also verify any destination directly at gsa.gov/travel.

Per diem during relocation (PCS)

If you are relocating on a Permanent Change of Station (PCS) order rather than TDY travel, per diem rules differ. During a PCS move, you receive a flat Miscellaneous Expense Allowance (MEA) rather than daily per diem, and your en-route travel days follow a reduced TDY rate. See the Federal Employee Relocation Guide for a full breakdown of PCS entitlements, DITY moves, and common claim mistakes.
