ACCONSIS is a holistic consulting company based in Munich. For over 60 years, we have been providing companies and wealthy private individuals with personal and trustworthy support.
More than 130 experts in the fields of tax and legal advice, auditing, financing and management consulting know their needs and the constantly changing requirements very well and advise them in five interlinked areas:
In focus: Structuring tax processes digitally
Legacy workflows often result in tool chaos, media breaks and unnecessary coordination effort.
Digital tax processes require structure: clear frameworks, clean interfaces and defined responsibilities.
We bring order to your tax organisation – digitally, efficiently and fully compliant.
