Changing tax advisor for a German GmbH.

Structured handover. Defined cut-over. Clear ownership from day one. We take over ongoing Accounting and Tax engagements for German GmbHs and organise the transition from the previous tax advisor. Before the handover, we clarify accounting records, payroll, tax filings, annual accounts, open matters and the date from which CLIQ takes responsibility.

Switching tax advisor is a handover project.

A switch should not start with two firms doing the same work or with nobody knowing who is responsible for the next VAT filing.

Before we take over, it needs to be clear what the previous advisor covered, which periods are closed, what remains open and from which date the new engagement starts.


We agree on that cut-over before the engagement begins.

Why companies change tax advisor.

Founders, managing directors and investors change tax advisor in Germany for different reasons.

Not every one of these points requires a change. But when the existing setup no longer fits the company, a structured transition can make sense.

Common triggers



Bookkeeping and reports keep arriving late.


Contacts and responsibilities are unclear.


The company has grown and the existing setup no longer fits.


Accounting, Payroll and Tax are handled by several providers.


Management Reporting has become more important.


A holding company or additional entities are added.


A business has been acquired.


The internal Finance function is being rebuilt.


You want more transparency around scope and fees.

How the transition works.

1. Understand the current scope.

We clarify what the previous advisor handles and how Financial Accounting, Payroll, annual accounts, tax returns and ongoing tax advice are organised today.

2. Identify open matters.

We determine which periods have been booked and closed, which filings remain outstanding and whether any accounting or tax matters are still unresolved.

3. Prepare the handover.

We define the data, documents and access required and clearly allocate responsibilities between the previous and new advisor.

4. Define the cut-over.

Before the handover, we agree from which period CLIQ takes responsibility for each ongoing service.

5. Start the new process.

After the handover, Financial Accounting, Payroll, Tax Compliance and other agreed services run under the new setup.

Changing during the financial year.

You do not have to wait until year end to change tax advisor for a German GmbH.

In practice, it needs to be clearly agreed who is responsible for which ongoing tasks and periods.


Key areas include Financial Accounting, VAT filings, Payroll, year-end work already in progress and outstanding tax returns.


The appropriate handover date depends on the existing engagement and the current status of the work.

Records required.

What we actually need depends on the company and the scope we take over.

Depending on the setup, relevant information may include



Company and entity details


Current Financial Accounting records


Accounts and balances


Open items


Prior-year annual accounts


Tax returns


Tax assessments


Current VAT information


Payroll data


Relevant contracts and tax documents


Information on ongoing tax audits or other open tax matters


Existing authorisations and access rights


Deadlines and outstanding filings

Accounting data and DATEV.

Changing tax advisor should not mean rebuilding existing accounting and tax data manually.

Before the handover, we clarify which systems contain the relevant data and how those records can be transferred into the new setup.


Where existing processes run on DATEV, we coordinate the available data, required access and organisational handover.

Tax authorisations and communication.

When the advisor changes, responsibilities towards the German tax authorities and other relevant bodies also need to be reorganised.

During onboarding, we clarify which authorisations and access rights are required for the agreed scope and which existing authorisations may need to be updated.

Financial Accounting.

When we take over ongoing bookkeeping, it needs to be clear through which period the previous advisor has completed the books and from which period CLIQ takes over.

Balances, open items, bank reconciliations and unresolved transactions should be documented at the point of transition.

Payroll.

Payroll requires a particularly clear handover date because the monthly payroll cycle continues throughout the transition.

Before we take over, we clarify previous payroll data, employee information, pending changes and the payroll period for which CLIQ will assume responsibility.

Annual Accounts.

It should be agreed early who will prepare the next annual accounts and the related tax returns.

This is particularly important where the financial year has already ended or the previous advisor has already started year-end work.


A clear allocation avoids duplicate work and gaps in responsibility.

VAT and ongoing Tax Compliance.

VAT filings and other recurring tax obligations continue during the transition.

At cut-over, we expressly agree which filings remain with the previous advisor and which are taken over by CLIQ.

Multiple German entities.

For groups with several German entities, the transition should be planned entity by entity.

Holding companies, operating companies and other entities may be at different stages and have different requirements.


For each entity, we define which services we take over and when the transition takes place.

Post-acquisition transition.

After an acquisition, the existing Accounting and Tax setup does not always fit the new ownership structure.

Reporting requirements may change, new holding or financing structures may be introduced and existing processes may need to be reorganised.


For acquisition entrepreneurs and investors, changing tax advisor can therefore form part of the post-closing setup.

Open matters.

Open tax questions, missing entries, unreconciled accounts or unfinished returns need to remain visible throughout the transition.

We record these matters during onboarding and agree which items should be completed by the previous advisor and which will move into the new engagement.


This prevents the new engagement from starting with unidentified legacy issues.

Coordination with the previous advisor.

A clean transition requires the relevant information from the previous engagement.

Where appropriate and requested by the client, we can coordinate the handover directly with the previous advisor.


The goal is a clear handover point with defined responsibilities rather than an unnecessarily long parallel phase.

Fees.

The transition itself is not a standardised product. The effort depends on the number of entities involved, the data and records to be transferred and any open Accounting, Payroll or Tax matters.

Ongoing fees depend on the agreed Accounting and Tax scope, bookkeeping volume, headcount, annual accounts, tax returns and additional advisory work.


Before we start, we define the scope and responsibilities.

Accounting and Tax in one setup after the switch.

Changing tax advisor is also an opportunity to reorganise the company's Finance processes.

CLIQ can combine Financial Accounting, Payroll, annual accounts, Tax Compliance and ongoing tax advice within one setup.


The services we take over are clearly defined before the engagement begins.

FAQ on changing tax advisor.

Can a German GmbH change tax advisor during the year?

A change can generally also be organised during the financial year. The appropriate timing depends on outstanding filings, the state of the books, Payroll and any year-end work already in progress.

Does the previous tax advisor have to agree?

The practical transition requires a clear handover of the relevant data and documents from the existing engagement. We clarify the required information and responsibilities as part of the onboarding process.

Can we switch tax advisor in the middle of the year?

Yes. What matters operationally is a clear allocation of periods and responsibilities for Financial Accounting, VAT, Payroll and other ongoing services.

What records does the new tax advisor need?

That depends on the company and the scope being taken over. Relevant records may include accounting data, prior-year annual accounts, tax returns, tax assessments, Payroll data and information on open tax matters.

Who prepares the annual accounts after the switch?

This should be agreed explicitly before the transition. Depending on the timing and progress of the existing work, the annual accounts may remain with the previous advisor or be taken over by the new one.

Can Payroll move as well?

Yes. Payroll can form part of the new setup. Because of the monthly payroll cycle, the handover date and responsibilities should be defined particularly clearly.

How long does a change of tax advisor take?

That depends on the existing setup, the number of entities, the completeness of the data and any open matters. A clearly defined cut-over is more important than a generic timeline.

What does the new tax advisor cost?

Ongoing fees depend on the scope and complexity of the engagement. Relevant factors include bookkeeping volume, group structure, Payroll, annual accounts, tax returns and ongoing advisory requirements.
