Tax Compliance Management Systems

What is a Tax CMS?

CMS means Compliance Management System. Compliance is an adherence with regulations and corporate guidelines, so a Tax CMS should make sure a company complies with tax rules.


Who needs a Tax CMS?

  • Large companies, esp. listed companies and those in the form of an “AG” (joint stock company) as for them it is mandatory by law or from the corporate government codex:
  • Board of directors must set-up and maintain an early risk detection system
  • Supervisory board or its audit or compliance committee must check, if the managing directors fulfil its duties
  • Companies with tax fraud, corruption, sales tax carousel or money-laundering cases in the past
  • Medium sized companies in certain business sectors, e.g.
  • Banks needs AML rules
  • Machine manufacturers need to manage product liability
  • Foreign sub-contractors must follow-minimum wage rules in Germany
  • Medium sized companies with activities abroad. Not checking out foreign rules does not help in case something goes wrong. In case the company is not able to find out the rules in other jurisdictions and check if they comply with them they must ask consultants for help.
  • Companies that are frequently in the media and must maintain a high reputation in the public
