  • what the three-month rule is

  • how is it triggered in the Circula app

  • the implication it has on submitters and accountants

What is the three-month rule?

Per diems received by employees of German companies correspond to financial compensation for the additional costs of food and accommodation when traveling. This means, they are not part of the employee's income and are therefore (up to a legal limit), tax-free.

However, these benefits are not unlimited and are capped at three months. After this three-month period, also known as the "three-month rule", or "Dreimonatsfrist" in German, these benefits are considered as income and are thus taxable.

How is the three-month rule detected in Circula?

Circula helps you identify when the three-month rule might apply. The following conditions need to be met:

  • The company is German

  • The employee travels regularly to a single location for more than three months

  • Each week, the employee stays in that location for more than two days

  • The project of the trip is the same, or all trips have no project listed

📝 Note: If a traveler doesn’t return to the same destination for the same project for 28 days, the 3-month rule doesn’t apply anymore and the counting restarts from zero.

❗️Please note,❗️once it has been marked that a trip falls under the three-month rule, the per diem amount is set to 0€ and the employee does not receive a refund.

Example

Example 1 - the three-month rule applies

Antoine works for the company ABC GmbH, based in Berlin. They want to open a new office in Hamburg. For this, Antoine travels to Hamburg from the 1st of September to the 15th of November. He comes back to Berlin and goes again to Hamburg from the 18th of November to the 8th of December.

In this case, Antoine spent more than 90 days in a single remote location for the same purpose. The three-month rule applies.

He will receive per diems for all the time spent in Hamburg, following to the relevant per diem rates. The per diems received starting on the 91st day (i.e. the 2nd of December) will be taxable as normal income according to German law.

Example 2 - the three-month rule doesn't apply

Leonard works for the company XYZ KG & Co, based in Munich. For business purposes, Leonard needs to go to London to visit customers.

He goes there from the 1st of July to the 31st of August to visit customer A.

He goes to London again from the 1st of October to the 15th of November to visit customer B.

Even if Leonard has spent more than 90 days in London, the purpose is different. The three-month rule doesn't apply.

He will receive per diems for all the time spent abroad, following the relevant per diem rates. The per diems will be tax-free.
