Frequently asked questions

What is a daily allowance?

A daily allowance, which is also known as per diem, is the limited amount of money an employee receives from their organisation to cover work-related expenses. Some examples of expenses include transportation or meals while traveling for business.

What are the features of the daily allowance for Mobilexpense?
  1. Customisable calculation: Companies can choose to follow our standard allowance calculation, or modify the rules to their unique needs.

  2. In-house compliance team: When using the standard allowance template, our compliance team ensures that the rates meet the latest legal requirements for each country. Controllers can sit back and relax, knowing compliance is taken care of.

  3. Easy trip entry: Users can enter the departure point, date, and time of travel. For multi-location trips, users can add multiple destinations and trips.

  4. Automatic calculation: The daily allowance is automatically calculated based on the entered trip details.

  5. Deductions: Companies can set policies for specific deductions from the original allowance. For example, breakfast may be deducted if included in the hotel price.

  6. Quick review and reporting: Users can review the total trip calculation with a few clicks. The calculated allowance can be easily added to an expense report for approval.

What are the benefits of the daily allowance module?
  • Ease of administration: Employees receive daily allowances without submitting detailed expense reports. This simplifies reimbursement and saves time for both employees and controllers.

  • Increased cost control: Daily allowances reduce the need for extensive documentation, allowing controllers to maintain better oversight and ensure compliance with company policies.

  • Better cost predictability: Finance teams can predict and budget for expenses more accurately with fixed daily allowances, providing financial stability for the organisation.

  • Higher employee satisfaction: Daily allowances streamline the reimbursement process and provide transparency, making it convenient and clear for employees to understand their allowances.

Which European countries does Mobilexpense support for per diem calculation?

Declaree by Mobilexpense supports per diem calculations across multiple European countries, including Belgium, the Netherlands, Luxembourg, Germany, Austria, and Finland, with support for both domestic and international per diem rules.

Our coverage continues to expand across Europe to meet local compliance and business travel requirements. If you would like to confirm support for a specific country or understand how per diem calculations work for your organisation, feel free to speak with your sales representative for more detailed information.

How does per diem work for multi-destination or multi-country trips?

Multi-day, multi-destination or multi-country trips are added in the same way as a normal journey in Declaree by Mobilexpense.

The main difference is that you will need to add each individual journey separately. A journey refers to travel from point A to point B, typically within one day. Any stopovers should also be included as separate journeys, and if no work is carried out during a stop, you can mark that journey as ‘Transit’. For example, if you are flying from Munich to New York with a layover in London, the London stop should be marked as a transit journey.

What is a deduction?

Based on the given parameters, a per diem may vary. The rates differ between countries, and even cities. In the case of a per diem for food, the employee will only receive the full allowance if they have paid for all their meals themselves. If not, deductions must be made for the per diem to be compliant. This can happen for example if the meals are included in the cost of the lodging, or if the employee’s meal is paid for in another fashion (e.g. as part of an event, by a customer/supplier, etc.).

How does Mobilexpense keep up with European per diems?

Declaree by Mobilexpense stays aligned with European per diems by using built-in logic and official tax rules for daily allowances (per diems). When you enter a business trip in Declaree, the system can automatically calculate the correct per diem based on the destination and applicable local rules, including deductions (e.g. meals provided) and different rates for domestic vs international travel. These calculations are based on current official per diem tables and can be activated in your Allowances settings if available.

Where can I find up-to-date per diem (daily allowance) rates?

When using the standard allowance template in Declaree by Mobilexpense, our in-house compliance team ensures that the rates meet the latest legal requirements for each country. Controllers can sit back and relax, knowing compliance is taken care of.

What's the difference between a per diem and an expense reimbursement?

According to the the Defense Travel Management Office: “Per diem is a set allowance for lodging, meal and incidental costs” incurred while on travel for business.

Expense reimbursement, meanwhile, is the repayment of money spent by an employee for business purposes. In a business context, employers may either reimburse actual travel expenses or provide a per diem (daily allowance), depending on company policy and local regulations.
