Forms, contracts, tax returns, bank and insurance documents as well as foundation documents regulate our everyday life. We take care of the formalities for you - enjoy the rest! Be it your private tax return or the entire outsourcing of the administration of your business.

ardnas consulting - Your challenge is our motivation.


Whether it's tax returns, VAT settlements or dealing with financial administration: taxes and accounting are our areas of expertise. With us, you have a clear view of your taxes and your business operations. For companies we take care of the entire company administration, payroll accounting and take care of the official matters.

Legal advice

Protect yourself before unpleasant surprises occur. We advise you on legal matters and guide you through the jungle of paragraphs so that you can concentrate fully on your business. We draw up new contracts or review existing ones. In addition to contract law, we advise you on corporate law, debt enforcement and bankruptcy law, tax law, property and inheritance law, as well as pension planning.


Resolving a conflict situation peacefully: This is possible thanks to mediation. Mediation promises lasting success because the parties to the conflict have worked out the solution together. Mediation is a legally recognized way of resolving conflicts. The mediator, as a neutral third party with appropriate training and no decision-making ability in terms of content, supports the parties by providing the structure and accompanying the process - but the mediator is neither a counselor nor a therapist.

About Us

Our experienced, well-trained and multilingual team (German, English, French and Spanish) supports you competently in the areas of fiduciary services, legal advice and mediation.

As a member of various professional associations, we always keep ourselves up to date with further training.

In focus


Tax optimization

  • Plan your payment into pillar 3a or the pension fund early enough. We recommend that you pay in your contributions by mid-December at the latest so that it also reaches the pension fund in good time.
  • Distribute the maintenance costs for your property sensibly so that you can deduct them in the most tax-optimized way possible.
  • Entrepreneurs can influence their tax bill by optimally splitting their salary and dividend payments.

We will be happy to show you these and other tax optimization options as well as the corresponding details in a proposal tailored to your needs.
