External audits

At regular intervals or “in exceptional cases”, the tax authorities conduct external audits on companies, freelancers or private individuals (operational audits). The larger the company, the more frequently the tax authorities take a look at the books, examining or amending the assessment bases of previous years. But sooner or later, everyone's number comes up!

Once the official auditor announces his visit for an operational audit, there is no need to get nervous. Thanks to targeted preparation and an abundance of detailed knowledge, you can take such an operational audit in your stride with us as experts by your side.

Our specialists support your operational audit right from the start, exploring issues in detail, handling verbal communication with the tax authorities, providing statements on disputed tax issues, asserting your interests and therefore ensuring a consensus which is satisfactory for everyone involved.
