Per Diem Rates by Location, Taxes, Pros and Cons

Per diem rates set a daily allowance for eligible business travel costs, usually covering lodging, meals, and certain incidental expenses. In 2026, continental U.S. meal and incidental rates fall into five tiers, from $68 to $92 a day. The exact allowance depends on the destination and the employer’s travel policy.

How per diem works and who sets the rate

Per diem means “per day.” Instead of reimbursing every qualifying travel purchase separately, an employer provides a fixed daily amount for specified expenses. The approach can make it easier to plan trip costs and process reimbursement, but the allowance is not a blank cheque: employees and employers need to follow the applicable rate rules and keep the required records.

For federal employees, the General Services Administration sets rates for locations in the continental United States. The U.S. Department of Defense sets rates for travel outside the continental United States, including Alaska, Hawaii, and U.S. territories, while the U.S. Department of State sets rates for international travel. Private employers may use General Services Administration rates as a reference for their own travel policies.

Rates are location dependent. A daily amount that fits one city may not apply in another, and lodging and meal allowances do not necessarily move together. Employers can set their own travel rules, but an employee should check which rate and reimbursement method the policy uses before leaving. A company’s allowance is not automatically the same as the federal standard.

For a traveler, the key distinction is between a fixed allowance and reimbursement of actual costs. Under a per diem arrangement, the allowance is set by policy and the relevant rate. The traveler still needs to provide the expense information the employer requires. Under actual cost reimbursement, the amount paid back is based on documented spending. Those methods can produce different results when real prices are above or below the allowance.

Before booking, ask the employer or travel administrator which dates, destination, lodging rules, and meal rate apply. Confirm whether the company uses the federal location rate or its own policy, and whether a separate lodging limit applies. This avoids assuming that a rate found online is the amount the employer will pay.

What 2026 per diem rates cover

Per diem generally has two parts: lodging and meals and incidental expenses, often shortened to M&IE. Meals means breakfast, lunch, and dinner. Incidental expenses include fees and tips paid to porters, baggage carriers, hotel staff, and staff on ships. The M&IE figure is a daily total, not a separate allowance for each meal.

The 2026 M&IE tiers for the continental United States are set out below. The source figures show a $5 incidental expense amount in every tier, while meal allocations rise as the overall daily total increases. High cost cities such as New York are in the highest tier, but a traveler should check the official rate for the specific location rather than infer the amount from the city name.

Lodging is a separate part of the allowance and varies by location. The General Services Administration considers local short term rental average daily rates, geography, fire safety certification, and property demographics when setting lodging rates. It uses average daily rate data from the trailing April to March period and accounts for seasonal changes using three years of historical average daily rate data.

That method means the lodging amount may vary by both destination and month. A traveler should not treat the M&IE tier as the full per diem for the trip: it covers meals and incidentals only. Check lodging separately, including the rate for the month of travel, and read the employer’s policy to see how a hotel cost is submitted or capped.

Per diem also does not necessarily cover every cost associated with travel. The stated categories are lodging, meals, and defined incidentals. Employees should find out whether other trip expenses are handled under a different reimbursement rule instead of assuming they fit into the daily amount. That question matters most when a traveler expects unusual costs or knows local prices may exceed the allowance.

How to look up a location and calculate travel days

The General Services Administration’s online per diem lookup tool lets users enter a state and a city or ZIP code. The results provide lodging rates by month and an M&IE breakdown for the location. Use the destination where the temporary duty travel takes place, then select the relevant month. When a trip includes more than one location or spans different months, confirm with the employer how it applies the rates to each part of the itinerary.

There is a specific rule for the first and last day of travel: employees are eligible for 75% of the total M&IE rate for the temporary duty travel location. The relevant location is not the employee’s official duty station. This adjustment applies to M&IE, so do not mistake it for a general reduction in lodging rates or assume the full daily meal amount applies on arrival and departure days.

A useful planning sequence is simple:

• Confirm the travel dates, destination, and temporary duty location with the employer.
• Look up the applicable M&IE and lodging rates for that place and month.
• Check whether the first and last travel days qualify for the 75% M&IE amount.
• Read the company policy for any internal limits, covered expenses, or required forms.
• Keep the details needed for an expense report, including date, time, place, amount, and business purpose.

This check is useful even when a traveler is not expected to submit a receipt for every meal. The tax treatment described for per diem depends on an expense report being filed, and the report must contain specific information about the expenses. The allowance does not remove the need for a record of the business trip.

For employers, the same steps help prevent an allowance from being applied to the wrong destination or travel day. Confirm the rate source, publish the company’s reimbursement rules, and tell employees what information must appear in their reports. A policy that explains the difference between lodging and M&IE can also make it clearer which costs fit within each part.

Tax treatment, documentation, and the trade offs

Per diem payments are generally not taxable to employees when handled as business expense reimbursements under the conditions described here. The employee must file an expense report with the employer, including the date, time, place, amount, and business purpose of the expense. The allowance must also stay within the allowable federal standard rate. If these conditions are not met, do not assume the payment receives the same tax treatment.

For employers, qualifying per diem expenses can be tax deductible. The practical point is that a fixed allowance still needs to be supported by the employer’s records and kept within the applicable standard. A simple payment process is not a substitute for checking the rate, keeping the report, or applying the policy consistently.

One important limit concerns extended assignments. If a person expects to work at a location for more than a year for business purposes, the expenses cannot be deducted as business travel expenses under the rule described in the source material. Since the tax consequences can depend on the circumstances, an employee or business facing a long assignment should ask a tax professional how the rule applies.

There are practical advantages to a per diem system. Employers can set a predictable travel budget instead of reimbursing every individual purchase. Employees may not have to collect and submit each receipt, although they still need to track expenses and file the required report. For accounting, a set allowance can also make the reporting process more straightforward than reviewing each actual expense separately.

The trade off is that a fixed amount may not match what a particular traveler spends. Someone can face costs above the allowance and have to pay the difference personally, depending on company policy. An employer can also pay more than an employee’s actual qualifying costs. Location and seasonal differences in lodging, along with changes in meal costs, make it especially important to verify the current rate rather than rely on an old trip’s figures.

Compliance is another consideration. Employers need to use the appropriate rate and maintain the required documentation. If an allowance exceeds the federal standard or the expense report is incomplete, the payment may not meet the stated conditions for tax free treatment. Employees should ask how to report a discrepancy rather than silently treating the entire allowance as tax free.

For employees, the most useful comparison is the allowance against likely trip costs and the written policy. A per diem payment offers a clear daily figure, but it may not cover every expense. For employers, the central choice is whether the convenience and predictability of a set allowance fit the travel needs of the staff. Neither approach removes the need to define covered costs and explain reimbursement procedures.

Will the allowance match the actual trip?

The answer depends on the destination, travel dates, hotel costs, and the employer’s policy. Before departure, check the current location rate, separate the lodging amount from M&IE, and confirm the reduced M&IE treatment for the first and last days. Then keep a complete expense report and ask the employer how any cost above the allowance is handled. Those steps make the allowance easier to use and help preserve the documentation needed for its tax treatment.
