Tax Consulting 4.0 - our digital services

We are shaping the future of tax consulting. Hannes & Kollegen is your partner on the way to the digitization of your accounting and financial reporting. With our electronic tenant PISA, you can easily exchange information with us, with banks and authorities - at any time, digitally and securely.
We'll create your paper bill. With our "Digital Accounts Payable Management" service, we can provide you with a complete digital processing of your incoming invoices - from entry through booking, to payment and archiving.

Classic Tax Consulting - what to expect anyway

Classic tax advice is natural to us. We create your financial accounting, payroll accounting, financial statements, tax returns and advise you in all tax matters.
We attach great importance to the quality of our work. For this reason, we regularly have our tax office management externally audited by TÜV Rheinland: We are certified according to the ISO 9001: 2008 standard and a holder of the quality seal of the German tax consultant association e.V.

Advice - individual and personal

Individual solutions for individual clients. In our consulting, we analyze the specific needs of your company to integrate the exact experts and services you need. We give you tailor-made, competent and interdisciplinary advice.

Your personal advisor keeps hold of the reins. This means that you are in the best hands during the whole company cycle - from start-up to business expansion and optimization to a possible sale.
