Money Matters
What does per diem mean, and what are the rates?

There are a few options available for paying your employees for business-related travel expenses: you can reimburse them for actual expenses incurred and submitted through an expense report, you can supply employees with business credit cards, or you can pay them per diem.
The per diem option provides employees with a fixed daily allowance to cover their travel costs and eliminates the need to manage high volumes of receipts required for expense claims. It saves accounting time and paperwork for the business and for employees when dealing with expenses. It also allows the business to better predict the costs of employee travel.
When used as part of a comprehensive travel policy, per diem reimbursement is a simple way to ensure travel expenses are tax deductible for the business and that employees are not taxed on the money they are reimbursed.

How does per diem work?
Per diem reimbursement covers the cost of meals, lodgings and any other travel incidentals such as parking fees for each day of business travel. Each expense has a predetermined rate as further explained below, based on the average costs associated with specific locations. Typically, a business pays a partial per diem rate for the first and last day of a trip, as the employee may spend part of those days at the office or at home.
Companies need to provide travel guidelines for their employees, containing a per diem policy clearly defining what is covered, and the rates used for all relevant locations.
Employees must submit daily reports to receive the reimbursement, and can spend up to their daily allowance limit. Employees can usually keep the difference if they spend under their limit, providing a valuable incentive to keep costs low and minimize expenses for the company.
How to calculate per diem rates
The United States General Services Administration (GSA) publishes per diem rates every year for locations within the continental United States. Rates for Alaska, Hawaii, U.S. territories, U.S. military installations and foreign countries are available through the United States Defense Travel Management Office.
Although the government uses these rates to reimburse federal employees for work-related travel, they are also often adopted by the private sector. That’s because businesses want per diem payments to be tax deductible and not be subject to income tax for employees, which means their rates cannot be higher than those set by the federal government.
The GSA rates are calculated annually and go into effect on October 1st, based on the most up-to-date cost data for various cities and counties. The two types of rate categories are: “Lodging Rates” and “Meals & Incidentals Expense Rates.” These are further broken down into standard and location-specific rates, and are displayed by month (e.g., the location-specific lodging rate for Boston is $185 in February 2022 and $264 in July). The index also has a travel tool which calculates the total per diem for your specified travel dates and location.
Per diem rates take into account the significant difference in living costs across states and cities. For example, the standard rate for lodging in 2022 is $96 per night, but for New York City, it ranges between $159 and $286 across the year. The rate for meals is usually $79 in New York City, whereas the standard rate is only $59.
How does a business pay per diem?
Companies can make these payments to employees either electronically or by check, and they should be issued separately from wages. Per diem reimbursements are not subject to taxes, including Federal Insurance Contributions Act (FICA) tax, however the IRS requires employees to submit their reports within 60 days of travel, otherwise the payments will be considered taxable income.
How is per diem taxed?
Employee travel expenses, including per diem reimbursements, are allowable business deductions provided they are backed up with an “accountable plan”. The IRS guidelines require expenses are business related, are adequately accounted for by a daily report submitted by employees, and any amounts exceeding the GSA set rates are returned by the employee within a reasonable time frame.
Per diem payments are not taxable for employees provided the required daily reports contain the following information: Business purpose of the expense, date, time, place and amount of the expense, and receipts for lodging. Employees don’t need to submit meal or incidental receipts with the report.
What is a per diem job?
A per diem job describes a contractor role or work completed on an as-needed basis. Per diem employees are paid a day rate, and the hours often vary from week to week. Since they aren’t regular, full time staff, per diem employees don’t receive benefits like healthcare, retirement plans, or paid time off.
This is a common type of role in the healthcare and education industries. Typically, schools pay substitute teachers at a per diem rate, which means they pay by work days rather than by hours worked. The substitute teacher may work for one day or multiple days depending on the needs of the school and the substitute’s availability.
In the healthcare industry, a travel nurse is a per diem role, as travel nurses typically take short term contracts with hospitals requiring extra coverage. Hospitals or clinics pay these shifts at a per diem rate, which averages out to a higher salary than a typical nurse’s salary. Travel nurses might work with a staffing agency who can offer them contracts in different hospitals across the country.
Advantages of a per diem job
Per diem roles obviously help companies fill gaps in coverage, but there are also many benefits for a per diem employee as well. Some employee benefits include:
- Higher salary: Per diem jobs offer higher rates because the roles generally do not include benefits, also employers sometimes offer premium pay for shifts around holidays or other busy periods to incentivize employees to take these shifts.
- Flexible schedule: A per diem employee can choose the number of shifts they take per week, which is especially helpful for students and others balancing responsibilities outside of work. A per diem employee also has no obligation to an employer after they complete their contract, allowing for time off between contracts.
- Gaining new experience: Employees can expand their skill set with each new role. Many workplaces use different systems, so they will have the opportunity to learn new technology, plus they will gain confidence interacting with new groups of people in new environments.
- Travel: Per diem jobs also allow employees to experience new locations, and can help them test out a new work place before making a commitment to a permanent role.
What are the differences between a per diem and part-time job?
A part-time employee works a set number hours in a pay period, generally fewer than 30 hours per week, and receives benefits based on how many hours he or she works.
On the other hand, a per diem employee’s work hours will vary from week to week depending on the employer’s need and how many shifts the employee wishes to take.
A per diem role pays by the day and is usually not eligible for employer benefits, therefore the per diem rate is generally higher to compensate for lack of benefits.
Final thoughts
Every employer wants a happy and engaged team, and two important components are building streamlined processes and job flexibility. So consider whether introducing one or both types of per diem could help take your business to the next level.
