GmbH Bookkeeping in Germany 2026: Obligations, Annual Accounts and Software

When you found a GmbH in Germany, bookkeeping obligations kick in immediately — and they go far beyond what freelancers are used to. Every GmbH must maintain double-entry accounting, produce annual accounts, and retain documents for up to ten years. Here is everything you need to know.

Legal Basis: Why GmbHs Must Use Double-Entry Bookkeeping

A GmbH (and UG) is legally classified as a Kaufmann (merchant) under the German Commercial Code (HGB), which means it is subject to mandatory double-entry bookkeeping regardless of turnover. Key legal provisions:

• § 238 HGB: general bookkeeping obligation for all merchants
• § 264 HGB: annual accounts (balance sheet + income statement) for corporations
• § 140 AO: tax bookkeeping obligations

Unlike sole traders or freelancers who can use the simpler cash-basis method (EIN), GmbHs must use doppelte Buchführung (double-entry bookkeeping): every transaction is recorded as both a debit and a credit.

Double-Entry Bookkeeping Explained

In double-entry bookkeeping, every transaction affects two accounts: a debit and a credit. This produces two key financial statements at year-end:

• Balance sheet (Bilanz): snapshot of assets versus liabilities and equity at year-end
• Income statement (GuV): all revenues and expenses for the financial year

Modern bookkeeping software handles the double entries automatically, as long as you consistently digitise receipts and record transactions.

Annual Accounts (Jahresabschluss): Deadlines and Requirements

Every GmbH must prepare annual accounts consisting of a balance sheet and income statement. Key deadlines:

• Preparation: within 3 months of year-end (small GmbHs: within 6 months)
• Publication in the Bundesanzeiger (Federal Gazette): within 12 months of year-end
• Tax returns (corporate and trade tax): 31 July of the following year

Micro-GmbHs (balance sheet total ≤ €350,000, revenue ≤ €700,000) only need to publish a simplified balance sheet.

Document Retention: How Long Must You Keep Records?

Under § 257 HGB and § 147 AO, GmbHs must retain business documents as follows:

• 10 years: accounting records, annual accounts, inventories, journals, balance sheets
• 6 years: business letters, tax-relevant emails

Digital documents are permitted as long as they are archived in GoBD-compliant format. See our guide: digital receipt management in Germany.

Costs of GmbH Bookkeeping: What to Budget

The cost of GmbH bookkeeping depends heavily on who does it:

• Tax advisor (Steuerberater): typically €150–500/month depending on volume and complexity
• In-house bookkeeper: from around €3,000 gross/month for a part-time role
• Bookkeeping software: from €15–100/month for GmbH-ready solutions

For early-stage GmbHs and UGs with manageable transaction volumes, AI-powered bookkeeping software is an increasingly cost-effective alternative to a full-time tax advisor.
