GmbH Bookkeeping Obligations in Germany 2026: Double-Entry Explained

Every GmbH and UG (haftungsbeschränkt) in Germany is legally required to use double-entry bookkeeping from day one — no opt-outs, no exceptions regardless of revenue. Unlike freelancers, who may use a simplified income-surplus calculation (EÜR), corporations are governed by the German Commercial Code (HGB), which mandates full double-entry accounting.

What is double-entry bookkeeping?

Double-entry bookkeeping records every transaction on two accounts simultaneously — debit and credit. This produces two financial statements at year-end: the balance sheet (assets, liabilities, equity) and the income statement (P&L). The simpler EÜR method is only permitted for freelancers and small sole traders whose revenue stays below €600,000 or profit below €60,000 per year. For any GmbH or UG, the EÜR is never an option.

Who must keep books?

Under §238 HGB, all merchants (Kaufleute) must keep accounts — and every GmbH and UG is automatically classified as a merchant by its legal form, regardless of revenue. Sole traders and freelancers only become subject to full bookkeeping when they exceed revenue of €600,000 or profit of €60,000. For corporations, those thresholds simply do not apply.

What does ongoing bookkeeping involve?

Ongoing bookkeeping for a GmbH covers recording all income and expenses on appropriate accounts, matching every transaction to a source document (receipt or invoice), filing monthly or quarterly VAT pre-returns (UStVA), and running payroll when you have employees. Annual tasks include preparing financial statements (balance sheet + P&L) and publishing them in the Bundesanzeiger (Federal Gazette).

GoBD compliance: storing receipts correctly

Germany's GoBD regulations set strict rules for document retention: a 10-year retention period for accounting records, immutable storage of digital documents, and guaranteed readability. Compliant software is not optional — a folder of scanned PDFs on your desktop does not meet the standard.

Key deadlines for GmbH and UG

The main deadlines: VAT pre-return (UStVA) due monthly by the 10th of the following month (or quarterly with a standing extension), annual financial statements due within 6 months of financial year-end (§264 HGB), corporate income and trade tax returns due by 31 July of the following year without a tax advisor, and Bundesanzeiger publication within 12 months of year-end.

Doing it yourself with modern software

Many GmbH founders ask whether they can handle bookkeeping themselves. The answer is yes — with the right tools. Modern AI accounting systems auto-categorize transactions, generate management reports (BWA), and prepare VAT returns. Norman handles ongoing bookkeeping for GmbHs and UGs including GoBD-compliant receipt archiving, reducing the tax advisor's role to the annual declarations. Learn about AI Bookkeeping →

Bottom line

Bookkeeping obligations are non-negotiable for every GmbH and UG in Germany. Double-entry accounting, GoBD-compliant records, and timely filings are the baseline. Founders who handle day-to-day bookkeeping with good software stay in control of their numbers and significantly reduce their accounting bills.
