Shareholder Loans to a GmbH in Germany 2026: Interest Rates, Tax and Accounting

GmbH and UG founders often need to inject additional capital into their company after incorporation — for working capital, investments, or short-term liquidity. Instead of the costly route of increasing share capital, many shareholders opt for a shareholder loan (Gesellschafterdarlehen): they lend money directly to their own company. This is entirely legal and can be tax-efficient — as long as you follow the rules.

What Is a Shareholder Loan (Gesellschafterdarlehen)?

A shareholder loan is a loan granted by a shareholder to their GmbH or UG. The shareholder becomes a creditor with a legal claim to repayment. Unlike increasing share capital, no notary or commercial register entry is required — just a written loan agreement and proper bookkeeping.

Shareholder Loan vs. Increasing Share Capital

Key advantages of a shareholder loan over a capital increase:

• The loan can be repaid at any time — share capital stays tied up permanently.
• No notary, no commercial register update — cheaper and faster.
• Interest paid reduces the GmbH's taxable profit, lowering corporate tax and trade tax.
• Ideal for short-term liquidity needs or financing individual projects.

Interest Rate: The Arm's Length Principle

The German tax authority checks whether the agreed interest rate is what an independent third party (e.g. a bank) would charge under comparable conditions — this is the arm's length principle (Fremdvergleichsgrundsatz). A rate that's too low or zero could be reclassified as a hidden profit distribution (verdeckte Gewinnausschüttung, vGA), triggering additional tax consequences.

Common benchmark rates range from 4–8% per annum depending on creditworthiness and loan duration. The rate must be stated in the written agreement and justified with reference to current bank rates.

Tax Treatment

For the GmbH, interest payments are a deductible business expense, reducing both corporate income tax and trade tax. For the shareholder, interest received is investment income subject to the 25% flat-rate withholding tax (Abgeltungsteuer) plus solidarity surcharge. This is often more tax-efficient than a profit distribution, which also triggers the flat-rate tax but doesn't generate a deduction at the GmbH level.

The loan agreement must be in writing, specifying term, interest rate and repayment schedule. Without a written agreement, the Finanzamt may reclassify the entire loan amount as a hidden profit distribution.

Bookkeeping and Balance Sheet Treatment

In the GmbH's bookkeeping, the shareholder loan appears as a liability ("Liabilities to shareholders", account 0350 under SKR03). Interest payments are posted as interest expense (account 7300). In the annual financial statements, shareholder loans must be disclosed separately on the balance sheet.

Risk: Subordination in Insolvency

Under § 39 of the German Insolvency Code (InsO), shareholder loans are subordinate in insolvency proceedings. You'll only receive repayment after all other creditors (banks, suppliers, tax authorities) have been paid in full. In practice, the shareholder loan is often lost entirely if the GmbH becomes insolvent.

Conclusion

A shareholder loan is a flexible and tax-efficient way to finance your GmbH or UG — provided it's properly documented, carries a market-rate interest, and is correctly accounted for. Norman helps you record shareholder loans accurately, track repayments, and keep your GmbH's books clean.
