The RLT partners stand for personal services and consulting.

Our clients are the focus and center of our activities. Each engagement is assigned personally to at least one partner. At the same time, the partners specialize in individual areas of concentration, depending on their training and professional activities, so that we are able to provide our clients with highly-specialized know-how within a short period of time. furthermore, the RLT partners exchange their professional experience and know-how on a regular basis. Thus, your RLT partner has all the insights in your situation and provides you with optimized solutions even for very specific issues in a one-stop approach.

The RLT team: highly qualified employees for personal services.

Our employees who have various skills and qualifications ensure personal consulting service at its best. About one third of the employees is qualified tax consultants and/or auditors. in addition to one partner who is in charge of the project, another permanent contact is available for the client‘s needs. This clear client-orientation is the key aspect of our corporate philosophy and the best basis for consistency, a trusting cooperation and holistic consulting services, even in complex matters.
