Frequently asked questions on audit
When is my company subject to a statutory audit in Germany?
Medium-sized and large corporations as well as partnerships with limited liability (e.g. GmbH & Co. KG) are subject to a statutory audit under Section 316 HGB. The decisive factor is the size category under Section 267 HGB (total assets, revenue, employees). I am happy to assess your situation in an initial consultation.
When is an ordinary or limited audit required in Switzerland?
An ordinary audit is required, among other cases, if two of the thresholds of total assets of CHF 20 million, revenue of CHF 40 million and 250 full-time positions are exceeded in two consecutive years. Otherwise a limited audit is sufficient – with no more than 10 full-time positions on an annual average, an opting-out is possible with the consent of all shareholders. You will find details on my Swiss website passion-revision.ch.
Do you work with tax advisers and fiduciaries?
Yes. I carry out audits for clients of tax advisers and fiduciaries – the tax work remains entirely with you.
Can you audit my company and advise it on tax at the same time?
Partly. Professional independence rules set limits. I check this in advance for every engagement and tell you openly which combination is possible.
Do you also audit groups with entities in Germany and Switzerland?
Yes. Licensed in both countries, I can audit or coordinate the German and Swiss entities of a group from a single source.
