Bahncard for Business Travel: When Employers Can Cover Costs Tax-Free

May 11, 2026

Business travel is a regular part of the workday for many employees. While flat-rate mileage allowances are often reimbursed tax-free for trips taken in a personal vehicle, a different rule applies when using trains and other forms of public transportation: In these cases, only the actual costs incurred—such as the price of a train ticket—can be reimbursed tax-free. A tax-free reimbursement in the form of a flat rate is not possible.

An interesting alternative can be the employer providing a rail pass. This is particularly worthwhile if business trips by train occur regularly. There are two options here: Either the rail pass is used exclusively for business travel or it is also authorized for personal travel.
If the rail pass is provided solely for business purposes, the tax treatment is clear—it remains completely tax-free.

In practice, however, private use is often permitted as well. In this case, it depends on whether the purchase “pays off” for the employer.
This means: If the savings from purchasing discounted tickets for business trips exceed the cost of the Bahncard, there is always a predominant business interest.

An example: If a Bahncard 50 costs around 244 euros per year and the employee saves more than this amount through regular business trips, there is a predominantly business-related interest. The result: The Bahncard remains tax-exempt.

However, it is important that this assessment be made at the outset. Employers should therefore estimate in advance whether the Bahncard is likely to pay for itself. The Deutsche Bahn forecast tool for the Bahncard 100 can be used for this purpose. https://bcbp.db-app.de/prognose/

Even if actual usage later turns out differently than planned, the original decision stands. There is generally no retroactive taxation.
