Peter W. Reiter

Tax Advisor


Peter W. Reiter advises our clients in particular in the field of classical tax consultancy.

He comes from a family of entrepreneurs and has been familiar with the day-to-day problems of companies from his very first professional steps.

His path to becoming a tax agent (1981) and subsequently a tax consultant (1988) took place in parallel with his career while working in two larger tax offices (in Trier and Mainz) with clients from a wide range of industries.

In addition to setting up his own practice in Mainz from 1981 and relocating to Stadecken-Elsheim in 1983, he also worked as a freelancer in a larger tax office in Wiesbaden in the initial phase.

His daily professional life was characterized by the classical services of a tax consultant. From the founding of companies to company successions, including the typical professional assistance for company management, to tax support for private individuals, a wide range of activities covers all types of taxes and representation vis-à-vis the tax authorities. The support of freelancers and tradesmen of the most diverse forms of enterprise from the most diverse industries led to an extensive specialized knowledge. He draws on many years of practical experience in the pragmatic implementation and support of tax returns, annual financial statements as well as payroll and accounting work, conducting tax audits and representing clients in out-of-court appeal proceedings.

As a member of the Datev cooperative since 1982, he uses the EDP programs typical for his profession and is thus always up to date with all legal changes and developments.

A particular personal characteristic of his work is the attitude of only looking after as many clients as is necessary to ensure that the professional can provide direct support at all times. This is therefore also reflected in long-standing client relationships.
