Business Banking for Holding Structures: Managing Accounts Across Multiple GmbHs

Business Banking for Holding Structures: Mastering Multi-Entity Banking

Why do successful founders create holding structures? Often for tax reasons, risk mitigation, or operational flexibility. But with multiple GmbHs comes new complexity: How do I organize banking for a holding group sensibly? Each GmbH needs a separate account. Yet these accounts must be coordinated.

This guide shows you how to set up banking for holding structures correctly in 2026, what technical and legal requirements exist, and which banks support this complexity best.

Why Does Each GmbH Need a Separate Bank Account?

This is not optional, but a mandatory consequence of the legal structure. Each GmbH is an independent legal entity with its own tax ID number. The tax authority, customers, and contract partners therefore expect each GmbH to have its own IBAN.

Separation is More Than Formality

Operating assets are legally separated from the holding parent company's assets. This means: subsidiary GmbH accounts must be strictly separate from holding company accounts. This separation is not merely a bookkeeping convention, but has concrete tax and liability consequences.

Mixing assets between holding and subsidiaries can trigger hidden profit distributions or group liability risks.

One Bank vs. Multiple Banks: A Strategic Decision

As a holding leader, you must decide: do I open all accounts at one bank or diversify across multiple banks?

Scenario 1: One Bank for All Accounts (One-Bank Strategy)

Advantages: centralized management, integrated treasury views across all entities, simpler interbank transfers, better negotiating power on fees.

Disadvantages: less flexibility for special requirements, risk that a banking crisis affects all accounts simultaneously, often higher risk profile for the bank.

Scenario 2: Multiple Banks (Multi-Bank Strategy)

Advantages: risk distribution across multiple banks, more independence in negotiations, specialized solutions for each GmbH.

Disadvantages: more complex management, fragmented financial control, higher manual reconciliation effort, potentially higher fees.

Our recommendation for 2-3 GmbHs: one-bank strategy. For 5+ GmbHs: hybrid approach (holding + 1-2 banks for strategic entities).

Cash Pooling in Germany: Physical vs. Notional

The heart of holding finance: how do you collect money from multiple GmbHs centrally without destroying the structure? The answer is called cash pooling.

Physical Cash Pooling

All revenues from subsidiary GmbHs flow to a central holding account. The holding manages the money and pays subsidiaries their expenses. This is transparent and simple, but has a downside: it could be interpreted as a hidden profit distribution if not properly documented.

Notional Cash Pooling

Each GmbH has its own account, but the bank offers a virtual pooling view. This lets the holding see consolidated liquidity without physically pooling money. This is cleaner from a tax perspective.

In Germany, notional pooling is especially available at banks like Qonto, Finom, and traditional corporate banks. German savings banks and cooperative banks often don't support it.

Comparison: Banks for Holding Structures 2026

Not all banks support holding banking equally well. Here is an evaluation matrix:

Which Provider for Which Use Case:

Startup holdings with 2-3 GmbHs: Qonto or Finom (best price-to-value, modern)

Medium holding with 3-10 GmbHs: Qonto (scales better, better API)

Large, complex holdings: Deutsche Bank or HSBC (full enterprise features, but high costs)

Intercompany Transfers: Documentation is Everything

Money flowing from subsidiary A to subsidiary B: this is normal business in holdings. But there's a big risk: hidden profit distributions (vGA - verdeckte Gewinnausschuettung).

What is Hidden Profit Distribution and Why is It a Risk?

Hidden profit distribution is a tax concept: if the holding treats its subsidiary better than would be customary in the market, the tax authority can interpret this as a hidden profit distribution. This costs taxes.

Example: the holding grants an interest-free loan to the subsidiary, while market-standard practice would expect 5% interest. The difference can be interpreted as a hidden distribution.

The Solution: Arm's-Length Documentation

Every intercompany transfer must be documented: why is the money flowing? Under what terms? At what interest rate or fee?

• Business loans: document interest rates, terms, repayment schedules
• Profit distributions: show they are market-conforming
• Service fees: prove services were actually provided
• License fees: if intellectual property is transferred between entities

Clean documentation could save you hundreds of thousands of euros in a tax audit.

Banking Permissions in the Holding: Who Can Do What?

With multiple GmbHs and multiple continents, a thorny question arises: who has access to which account? The answer is complex and legally critical.

Power of Attorney vs. Prokurist vs. Officer Role

Power of attorney is the most common solution. The holding CFO receives power of attorney for all subsidiary accounts. This is practical, but only if the GmbH managing directors agree. Prokura is an officially certified form (registry entry), power of attorney is more private.

Best Practice: Role-Based Access Control

Modern banks like Qonto and Finom offer role-based access control: CFO can spend and view money, finance manager can export reports but not start transactions, accounting can only see account statements.

This is cleaner and prevents errors and fraud.

Consolidated Bank Statements and DATEV Export

Accounting becomes more complex for holdings: you must coordinate accounts of multiple GmbHs in one bookkeeping system. Often DATEV is used for consolidation.

Good banks for holding structures support DATEV export or standard interfaces (MT940 or APIs). Qonto has much better integration here than traditional banks.

Ask your bank account manager: how do we export all GmbH accounts to DATEV? The answer shows whether the bank really supports holdings or just serves smaller businesses.

Treasury Management: Beyond Banking

Eventually a business account alone is no longer sufficient. You need treasury management: a system that optimizes cash flows across all entities, forecasts liquidity, and plans investments.

Software like Agicap, Kyriba, or bespoke solutions might make sense. But this is only relevant when you have 10+ GmbHs or billion-euro turnover holdings.

Practical Setup: Account Structure for a 2-Entity Holding

Suppose you have a holding GmbH and two operational subsidiary GmbHs. The structure could look like this:

• Holding GmbH main account: for investments, loans to subsidiaries, strategic revenue
• Holding GmbH sub-account: for taxes and fees
• Subsidiary GmbH-A main account: operating income and expenses
• Subsidiary GmbH-A sub-account: for tax reserves
• Subsidiary GmbH-B main account: operating income and expenses
• Subsidiary GmbH-B sub-account: for tax reserves

That's a total of 6 accounts at one bank. Most modern banks allow this.

Practical Setup: Account Structure for a 5-Entity Holding

For more complex holdings, a multi-bank strategy becomes interesting:

• Qonto: holding GmbH + 4 subsidiary GmbHs (total 5 accounts)
• Finom: 1 additional subsidiary GmbH with special requirements (e.g. EU expansion)
• Plus: treasury software for pooling and financial planning

This hybrid structure offers flexibility and is still manageable.

Hidden Distribution Risks in Intercompany Financing: A Case Study

Scenario: holding grants interest-free loan to subsidiary to quickly finance growth. The tax authority might argue that market-rate interest would be at least 3-5% (depending on market rates). The difference would be a hidden distribution.

Better: loan agreement with explicit interest rate (e.g. 3% p.a.), documented in the GmbH records. That's clean and defensible.

Growth: When You Scale from 2 to 10+ GmbHs

Many founders start with 2-3 GmbHs then scale to 10+ entities. This is a turning point where the banking strategy must be reconsidered.

At 10+ GmbHs, enterprise solutions (Deutsche Bank, HSBC) or treasury software integration often makes sense. Qonto and Finom are scalable, but eventually the system becomes too complex.

Checklist: Setting Up a Holding Banking Structure

• Decision: one-bank vs. multi-bank strategy (based on number of GmbHs)
• Select bank with multi-entity support
• Open all GmbH accounts with clear naming scheme (e.g. 'HOLDING-Name-Account', 'Subsidiary-A-Account')
• Build access management: who has power of attorney for which accounts?
• Prepare intercompany documentation (loan agreements, service contracts)
• Test DATEV/accounting integration
• Build reporting dashboard (consolidated liquidity view)
• For 5+ GmbHs: evaluate treasury software

Summary: The Ideal Holding Banking Strategy

There's no one-size-fits-all approach to holding banking. But best practice is:

• For 2-3 GmbHs: Qonto or Finom with one-bank strategy
• For 3-5 GmbHs: Qonto with notional cash pooling
• For 5-10 GmbHs: Qonto + 1 specialized bank or treasury software
• For 10+ GmbHs: Deutsche Bank or HSBC with full enterprise setup
