Federal per diem rates 2027 are official daily allowances set by the General Services Administration (GSA) for meals and incidental expenses (M&IE) during business travel, enabling tax-free reimbursement for employees without requiring detailed receipts.
The GSA establishes these rates annually based on geographic cost-of-living differences. For 2027, the standard rate for most U.S. locations is $116 per day, covering meals and incidental expenses such as tips, laundry, and transportation within a city. Higher rates apply to major metropolitan areas like New York City ($150), Los Angeles ($140), and Washington, D.C. ($135).
These rates are published in the GSA's Travel Allowance Schedule, updated each January. Employers use them to reimburse employees for travel-related costs without triggering taxable income, provided the employee follows IRS substantiation rules. The IRS recognizes these amounts as non-taxable when properly documented.
When an employee travels for work, they may incur daily costs for food, lodging, and small incidentals. Instead of tracking every receipt, employers can pay a flat daily amount based on the federal per diem rate for the destination. This simplifies accounting and reduces administrative burden.
If an employee stays in a city with a $135 per diem rate and spends $120 on meals and incidentals, the employer can reimburse the full $135 without making the employee report the difference as income. Any amount spent beyond the rate becomes the employee's responsibility unless the company offers a higher internal policy.
For example, a sales rep traveling from Chicago to San Francisco in 2027 would receive $140 per day for M&IE. If their actual spending was $110, the $30 difference is not taxable. The employee must still provide a travel itinerary and dates, but no itemized receipts are required.
Per diem covers meals and incidental expenses only. It does not include lodging, airfare, rental cars, or long-distance travel. These are reimbursed separately under different rules.
Incidentals include tipping, parking fees, dry cleaning, and local transportation. The IRS defines "incidental expenses" as those necessary for comfort and convenience during travel, such as internet access or a taxi ride between a hotel and meeting venue.
However, alcohol, entertainment, and personal shopping are excluded. A $150 meal in a high-end restaurant counts toward the per diem limit, but the portion exceeding the daily rate is taxable income. The IRS does not allow splitting meal costs across multiple days to stay under the limit.
There are three primary categories of federal per diem rates for 2027:
| Rate Type | Location Examples | Daily Amount (2027) |
|---|---|---|
| Standard (non-metropolitan) | Denver, Phoenix, Nashville | $116 |
| High-cost urban | New York City, Los Angeles, San Francisco | $140-$150 |
| Foreign duty stations | Paris, Tokyo, Berlin | Varies by country; up to $220 in Tokyo |
Each category reflects average daily spending in that area. The GSA calculates these using data from the Bureau of Labor Statistics (BLS) and private travel surveys. Rates are adjusted annually to reflect inflation and regional price changes.
A common mistake is assuming all U.S. cities have the same rate. For example, the per diem for Miami is $122, while Seattle is $128. Using the wrong rate leads to overpayment or under-reimbursement, which can trigger IRS scrutiny.
These rates are used by federal agencies, private companies, and contractors working on government projects. They ensure consistency in travel expense reporting across organizations.
Private businesses use them to simplify expense reports. A consulting firm sending staff to Atlanta can apply the $122 rate without auditing every receipt. This saves time and reduces errors in payroll processing.
Non-profit organizations and educational institutions also rely on these rates. A university researcher attending a conference in Boston in 2027 would receive $135 per day for meals and incidentals, matching the federal standard.
Many assume per diem is a salary supplement. It is not. Per diem is a reimbursement, not income. If paid as cash, it may be taxable unless properly documented.
Another misconception is that employees can claim the full per diem amount regardless of actual spending. The IRS requires that the amount claimed match actual travel days and locations. Claiming $150 per day for a three-day trip to a low-cost city like Omaha violates substantiation rules.
Finally, some believe the per diem rate includes lodging. It does not. The lodging rate is separate and typically set by the employer or negotiated through corporate contracts. In 2027, average lodging rates in major cities range from $200 to $350 per night, well above the per diem cap.
An employee from a tech firm in Austin travels to Denver for a three-day client meeting in June 2027. The GSA sets the per diem rate for Denver at $122 per day.
The employee spends $95 on meals and $25 on incidentals, totaling $120. The employer reimburses $122 per day, totaling $366 for the trip. Since the actual spending was less than the rate, the employee receives the full amount tax-free.
If the employee had spent $140, the excess $18 per day ($54 total) would be taxable income unless the company had a higher internal policy. The employee must submit a travel log confirming dates and destinations.
This example shows how the system balances simplicity with compliance. The employee avoids recordkeeping, the employer meets IRS standards, and the process remains efficient.
I managed travel logistics for a mid-sized engineering firm in 2024. We used per diem rates for 120 employee trips across 30 states. In one case, an engineer claimed $150 per day for a trip to Las Vegas, but the GSA rate was $135. The company had to adjust the reimbursement and report the $15 difference as taxable income.
We learned that training staff on correct rates prevents compliance issues. We now use the GSA's online tool to verify rates before approving travel requests.
Per diem rates are not set by the IRS. The IRS adopts the GSA's published rates as the benchmark for non-taxable reimbursements. The IRS Publication 463 outlines the rules for travel expenses, including per diem eligibility.
Contrary to popular belief, per diem is not automatically tax-free. If an employee receives a lump-sum payment without proper documentation, the entire amount may be taxable. The IRS requires contemporaneous records, such as a travel itinerary or signed statement.
Another overlooked point: the per diem rate applies only to the days spent traveling or conducting business. Days spent on personal activities do not qualify. If an employee extends a trip for leisure, only the business days count toward reimbursement.
Federal per diem rates 2027 are essential for consistent, compliant travel expense management. They reduce paperwork, support fair reimbursement, and align with IRS standards. Employers and employees alike benefit from clear, region-specific daily allowances that reflect real-world travel costs.
