Per diem has two distinct meanings: a daily travel allowance for business expenses, or a day-by-day pay arrangement with no guaranteed hours. They’re unrelated, despite the shared name.
What is per diem?
In payroll and travel policy, per diem is the flat daily rate a company pays employees to cover meals, lodging and incidentals on a business trip, so nobody has to file a stack of receipts afterward.
In hiring and scheduling, per diem means something different: bringing someone on to work a shift here and there, with no fixed schedule and no guarantee of regular hours. It’s common in healthcare, hospitality, retail and restaurants, though healthcare usually calls it PRN instead.
Which meaning applies comes down to context.
- A payroll admin setting per diem rates or asking “what’s our per diem policy” is almost certainly talking about travel.
- A hiring manager asking “should we bring her on per diem” is talking about scheduling.
The rest of this entry walks through both meanings.
Where the term “per diem” comes from
Per diem is Latin for “by the day” or “per day.” It entered English through both military and government travel administration (a daily travel allowance) and through industries like healthcare, where workers are scheduled on a day-by-day basis (often called PRN, from the Latin pro re nata, meaning “as needed”).
Per diem in business travel
When a business sends an employee on a trip, per diem is the daily rate the company pays to cover:
- Meals and snacks
- Lodging
- Incidentals, like tips, parking and business-related supplies
Instead of collecting and approving individual receipts for every expense, the company pays a flat daily amount and the employee manages their own spending within it. Most companies set their per diem rates using the U.S. General Services Administration’s federal per diem rates as a benchmark, even though private employers aren’t required to use them. Staying within the federal rate keeps the reimbursement non-taxable without extra documentation, which is the main reason most businesses anchor to it rather than setting a number from scratch.
Current GSA standard rate: For fiscal year 2026 (October 1, 2025 through September 30, 2026), the standard CONUS per diem rate is $178 per day — $110 for lodging and $68 for meals and incidental expenses (M&IE). The GSA kept this rate unchanged from FY2025. Roughly 300 higher-cost cities and counties have their own non-standard rates above the baseline, and those rates can change month to month, so always check the current rate for the destination and travel dates rather than relying on the annual average.
The IRS also publishes a simplified “high-low” method that uses two flat rates (one for high-cost localities, one for everywhere else) instead of requiring a city-by-city lookup. If your business uses this method, check the current rates directly against IRS guidance for the applicable year, since the high-low figures are easy to find misquoted on older or third-party sites.
How to calculate per diem
Multiply the applicable daily rate by the number of travel days, with one adjustment: the first and last day of a trip are typically reimbursed at 75% of the M&IE rate, since the traveler isn’t away for the full day. For example, a 3-day domestic trip at the FY2026 standard rate would work out to:
- Day 1 (departure): 75% of $68 M&IE + full lodging
- Day 2 (full day): full $178
- Day 3 (return): 75% of $68 M&IE + full lodging
Under a standard tax-free accountable plan, lodging is typically reimbursed at actual cost up to the cap, not as a flat allowance; if the hotel costs less than the rate, the employee doesn’t keep the difference on the lodging portion the way they might with the M&IE portion.
Is per diem taxable?
Generally, no. Per diem payments aren’t considered taxable wages as long as the amount doesn’t exceed the applicable federal rate and the employee adequately accounts for the time, place and business purpose of the trip—what the IRS calls an accountable plan. Per diem becomes taxable income when an employer pays a flat daily amount without requiring any expense reporting, or when an employee doesn’t file required documentation within the IRS’s standard window after the trip. Amounts paid above the federal rate are taxable on the excess, even under an otherwise compliant plan.
Per diem as a type of employment
Outside of travel, “per diem” describes how a worker is scheduled and paid, not how much they’re paid. A per diem employee:
- Has no guaranteed hours or recurring schedule
- Is offered shifts as they come up and can typically accept or decline them
- Is paid hourly for time actually worked, not a flat daily rate
- Is a W-2 employee, not an independent contractor
That last point trips up a lot of employers. The flexibility of per diem scheduling doesn’t change the worker’s legal status — if you control when, where and how the work gets done, that’s still an employment relationship under the FLSA, and treating a per diem worker as a 1099 independent contractor because their hours vary is a common misclassification mistake.
Per diem workers often earn a somewhat higher hourly rate than employees in similar part-time or full-time roles, since the premium offsets the unpredictability of the schedule and the lack of guaranteed hours.
Per diem vs. PRN
If you operate in healthcare, you’ll see PRN used instead of (or alongside) per diem. They describe the same kind of arrangement (as-needed scheduling, no guaranteed hours), but PRN roles typically come with their own licensure or credentialing requirements that don’t apply to per diem work in other industries. Facilities that lean heavily on PRN staff, like skilled nursing and long-term care, also tend to need tighter scheduling just to keep shifts covered. For more on managing labor costs in that environment, see our SNF and LTC scheduling and labor cost guide.
Per diem vs. part-time
The difference comes down to predictability. Part-time employees work a regular, recurring schedule, even at reduced hours. Per diem employees work whenever a shift is offered and accepted, which could mean a full week one month and nothing the next. Part-time roles are generally a better fit when you need consistent coverage and want to invest in training; per diem fits unpredictable demand, call-outs, seasonal spikes, special projects.
Per diem vs. temporary employment
Temporary workers are hired for a defined period with an expected end date, often through a staffing agency. Per diem workers stay on your roster indefinitely with no end date, available to pick up shifts whenever you need coverage.
Per diem employee rights and compliance basics
Per diem employees keep the same baseline legal protections as any other employee, regardless of how irregular their schedule is:
- Overtime: Hours worked over 40 in a workweek require overtime pay at 1.5x the regular rate, the same as for any hourly employee.
- Minimum wage and recordkeeping: Federal wage and hour laws apply in full.
- Anti-discrimination protections: Per diem status doesn’t reduce or change an employee’s protections under federal anti-discrimination law.
- Classification: Per diem workers are employees, not independent contractors, and most are non-exempt under the exempt vs. non-exempt distinction given the hourly, variable nature of the work.
State and local rules layer on top of federal requirements — some states have their own paid sick leave accrual or predictive scheduling rules that apply regardless of how irregular the schedule is, so check state requirements before finalizing a per diem policy.
Managing per diem for the hourly economy
Whether you’re building an as-needed per diem staffing pool or setting a travel expense policy, managing a variable workforce comes with real administrative weight: tracking worker classification, irregular hours and multi-site compliance across people who rarely work the same schedule twice.

Time tracking, employee cheduling and payroll live natively in one system, so per diem shifts, overtime and regular hours flow into the same pay run without manual reconciliation between separate tools. If you run into a question while setting up per diem rates or managing a mixed schedule, you can call Fingercheck support directly. A real person answers in under a minute, so you don’t have to deal with a bot or ticket queue.
