How does a CONCEPTer actually work?

Being a CONCEPTer means being responsible for working out practicable solutions to tax and business management issues on behalf of the client. Independent work is our priority. Nevertheless, this does not mean being "left alone" with us. We appreciate and encourage teamwork. Because we develop solutions as a team!

With us, you can expect a permanent position at attractive conditions, independent work directly with the client, continuous training, a very friendly group of colleagues and, of course, support in taking the professional examinations (auditor, tax consultant, accountant
etc.) Apply on your own initiative.

Are you looking for a future-oriented profession that fulfills you, but also constantly challenges you? Start your professional future with an apprenticeship as a tax clerk (m/f/d) or begin your studies of business administration dual (B. SC.) in cooperation with the University of Applied Sciences Mainz. You are welcome to complete a short-term internship with us - after scheduling an appointment - to get a taste of what it's like.By the way, the vocational school is also located in "cycling distance" to our office. Of course, after successful completion of the apprenticeship, we usually offer a permanent position to the tax clerks trained by us.

New challenges every day

Much more than just an apprenticeship

"I started at Concept immediately after my apprenticeship and now, after more than 20 years, I'm still with them. During this time we have grown together. The firm and its tasks, the number of employees, and the location as I have grown in my job responsibilities and my personal/family life. I enjoy working at Concept. Because of the diverse tasks and the constant changes and innovations, it never gets boring. Our team harmonizes, new employees are quickly integrated. We colleagues help each other and the partners are always ready to help with advice and support. The training courses are extensive and take place regularly. Professional further training is welcome and is encouraged, for example, I have successfully completed a two-year further training course to become an accountant".

Sandra Buchheim

Accountant, CONCEPTer since 1999

"After I had passed my tax consultant exam while working for the tax authority, I was very happy to be able to return to my roots as a tax consultant and thus to my former training company. Whether as an apprentice or as a tax consultant, I always feel welcome and well looked after. And even now, as a mom working part-time, Concept's flexibility and advanced digitalization give me the opportunity to combine family and career, tailored to my needs.”

Romina Dietzen

Tax consultant, CONCEPTer since 2016

"I started my training at Concept in August 2015 and successfully completed it in 2018. Since then, I have been completing a dual course of study at Mainz University of Applied Sciences. In order for me to be able to pursue this, I am supported by Concept in many ways. For example, flexible adjustments of my working days to my studies are no problem due to the flexitime offered. My main area of responsibility is the preparation of tax returns, annual financial statements and financial accounting. I particularly enjoy the daily change of tasks and working in a team."

David Stenner

Tax assistent, Tax clerk with Master of Arts in Taxiation degree programme, CONCEPTer since 2015

"I started my dual studies in combination with my training as a tax clerk in 2017 at Concept. During my training, I was granted one day off a week to attend lectures at the university. I was also provided with the necessary training materials free of charge. I was happy to take on the responsibility of being the social media representative for, among other things, our Instagram Account."

Assistant tax consultant with dual B.Sc. degree in business studies, CONCEPTer since August 2017
