Checklist: changing your tax advisor.
The switch step by step — without a support gap and without friction.
- 01
Engage the new advisor first — then terminate
No gap: the new engagement stands before the old one ends.
- 02
Grant powers of attorney
Receipt and representation authority — templates from us.
- 03
End the existing engagement
Informal text form usually suffices; open work is either finished by the previous firm or taken over.
- 04
Have records and data handed over
Between DATEV firms this runs as a complete migration.
- 05
Inform the tax office
The new receipt authority is filed; mail now runs via the new firm.
- 06
Set up document flows
DATEV access, bank feeds, rhythms for documents and payroll.
- 07
Check open deadlines
Running extensions and upcoming filings are taken over and scheduled.
