Welcome

Welcome to REB

Onboarding made simple.

A systematic onboarding process. Your easy start with REB.

We make your transition to us a seamless process.

Starting a new advisory relationship should not be an additional burden. That is why we have fully integrated the entire switching process – from terminating your previous advisor to transferring all data – into our digital workflows.

The 2-phase start:

1

We handle the switch for you.

We take care of all formalities with your previous tax advisor – including powers of attorney, mandate termination, and structured retrieval of all relevant documents and data. You sign – we handle the rest.

2

Digital start: DATEV onboarding.

For optimal, secure collaboration, we guide you through the DATEV online applications. We use the DATEV onboarding tool to capture all master data and information digitally and in an audit-proof manner.

How your digital start works:

1.

Email invitation:

You receive a personal invitation link from us to register your free DATEV user account.

2.

Master data entry:

Through a user-friendly, guided process, you enter all required information (company and personal data). The data is immediately transferred into our firm's system – ensuring the highest data quality without media breaks.

3.

Secure access:

We then set up your authenticated access, allowing you to immediately use the relevant applications (e.g. DATEV Unternehmen Online or DATEV Meine Steuern).

Your advantage:

The entire onboarding process is transparent, time-efficient, and lays the foundation for maximum data security and efficiency in our future collaboration.

Become a client

Those who don't move with the times will be left behind.

Unhappy with your current tax advisory?

Switching is easier than you think.

Under § 627 of the German Civil Code (BGB), you can switch to us at any time – without complicated hurdles.

With REB, step directly into the future.

All you need to do: book a meeting and grant us a power of attorney.

We take care of the rest:

  • We notify your previous advisor.
  • We retrieve all data and documents.
  • We handle the tax office and all authorities.

You pick up seamlessly where your former advisor left off – only better.

We look forward to hearing from you

FAQ

Answers, not questions

What services do you offer?
It depends entirely on your needs. For businesses, we cover the full spectrum of tax advisory, including tax structuring, financial accounting, payroll, annual financial statements, and all required tax returns. We also assist with business consulting, digitalisation, and data protection. For private individuals, we prepare your annual income tax return and advise on investment decisions or any matter where tax law plays a role.
I am not based in Osnabrueck. Can I still engage your firm?
Absolutely. We serve clients across Germany and internationally. Our fully digital infrastructure allows us to provide all services regardless of your location. We are also happy to arrange in-person consultations at your premises when needed.
Do I really need a tax advisor?
German tax law is among the most complex in the world. Whether you are a business owner facing intricate corporate tax rules, a private individual with rental income or foreign earnings, or simply someone who wants certainty that every tax benefit is claimed – professional tax advisory gives you the security that your tax affairs are handled correctly and efficiently.
I am starting a business and need a tax advisor. How can you help?
We start from scratch with you: invoicing, cash management, ongoing financial accounting, VAT returns, and more. We represent you before the tax authorities, handle payroll when you hire your first employees, prepare annual financial statements and tax returns, and manage all correspondence with the tax office. We are always available for questions – whether it concerns a tax audit or day-to-day tax matters.
