Our Services


We provide you with certainty and objectivity with regard to your annual financial statements and will also provide you with a customised and practical assessment of the opportunities and risks of the financial reports.

Tax consultancy

It is your duty to pay tax but it is your business responsibility to minimise tax liabilities. Within what is legally possible, we see our task to be the development of solutions for our clients which lead to the optimisation of tax payments.

Trustee services / Consultancy

Your administrative problems become our assignments. We support both small and medium sized enterprises as well as private individuals with comprehensive advice which we tailor to meet your specific circumstances.

Mergers & Acquisition

Companies are in a permanent state of change. Processes must be altered. New situations demand new knowledge.

We would be happy if Ostschweizerische Treuhand Zürich AG could act on your behalf and we would be delighted to explain our services to you in a face-to-face conversation - with no obligation.
