Where Tax Expertise Meets Perspective

opportax Tax Advisory

Some tax matters arise from change: a new phase of life, international professional activities, significant private or business decisions, or questions relating to assets. Others develop naturally from everyday circumstances – such as income, rental property or investments. In both cases, opportax is at your side.

opportax follows the guiding principle “opportunities in taxation” – an approach to tax advisory that assesses tax matters with foresight and creates room for well-founded decisions. With technical precision, a clear view ahead and the understanding that good tax advice must provide orientation.

Rooted in Hamburg, we work digitally and independent of location. Modern processes enable efficient collaboration – from recurring tax matters to more complex issues – personal, reliable and accessible wherever you are.

Personal and Responsible Advice

Certified Advisor in International Taxation | Fachberater IStR
Founder and Managing Director of opportax

Tax matters are rarely just about numbers. They are often connected to decisions, uncertainties or simply the wish to know that one’s affairs are well organised.

This is where my work begins. It is important to me that tax advice does not become more complicated than tax law already is, but remains clear, reliable and human. Clients should feel well supported and know exactly where they stand.

I founded opportax to offer tax advice the way I would expect it myself: with time for the matter at hand, a clear focus on what truly matters and a relationship built on mutual respect. Digital and efficient – yet always personal.
