Setting up accounting for a German GmbH: from chart of accounts to year-end

The setup path, end to end

A GmbH must keep double-entry commercial books from formation (§ 238 HGB) and prepare an opening balance sheet, then a Jahresabschluss each year-end (§§ 242, 264 HGB). Setting up well means the year-end is a short mapping exercise, not a scramble.

The sequence is: pick a chart of accounts, register for VAT, run disciplined bookkeeping to a monthly trial balance, and then map that trial balance into the HGB Bilanz and GuV at year-end. Get the first three right and the fourth is straightforward.

Choosing a chart of accounts: SKR03 vs SKR04

German bookkeeping runs on a standard chart of accounts (Standardkontenrahmen). The two dominant choices are SKR03, ordered by process (Prozessgliederung), and SKR04, ordered along the financial-statement structure (Abschlussgliederung). Both map cleanly to HGB; SKR04 mirrors the § 266/§ 275 layout, which many find tidier for year-end.

Pick one and stay consistent. The choice affects account numbering and how naturally your trial balance lines up with the statutory captions, not whether you can comply.

VAT registration and its link to bookkeeping

Most trading GmbHs need a VAT registration and a VAT number (USt-IdNr.) for intra-EU trade. From there you file periodic advance VAT returns (Umsatzsteuer-Voranmeldung), monthly or quarterly, reporting output VAT less input VAT (Vorsteuer).

This links straight to bookkeeping: every invoice you post carries a VAT code, and the net VAT payable to or receivable from the Finanzamt flows through the balance sheet. Clean VAT coding during the year is what makes the year-end reconciliation painless.

Bookkeeping to trial balance

• Post every transaction by double entry against the SKR03/04 accounts.
• Code VAT consistently so input and output VAT reconcile.
• Reconcile the bank, receivables and payables monthly.
• Produce a monthly trial balance (Saldenliste / Summen- und Saldenliste).
• Keep supporting documents — the Belegprinzip means no posting without a document.

From trial balance to the Jahresabschluss

At year-end the trial balance is mapped to the HGB taxonomy: each account into its Bilanz caption (§ 266) or GuV line (§ 275). Accruals, provisions, depreciation and deferred items are posted, and the abbreviated presentation for your size class is applied.

This is where jahresabschluss.io does the heavy lifting: upload the Saldenliste and the AI maps it to the HGB structure, drafts the Bilanz, GuV and Anhang, and exports the German filing document with an English convenience translation. A micro or small GmbH can complete the whole year-end without an audit (§ 316 HGB).

Frequently asked questions

SKR03 or SKR04 for a GmbH?

Both are valid German standard charts of accounts and both map to HGB. SKR03 is ordered by business process; SKR04 follows the financial-statement structure (§ 266/§ 275), which many find cleaner for year-end. Choose one and stay consistent.

Do I need VAT registration for a German GmbH?

Most trading GmbHs do, along with a USt-IdNr. for intra-EU trade. You then file periodic advance VAT returns reporting output VAT less input VAT (Vorsteuer), which flows through the accounts.

What is a Saldenliste or trial balance?

The Summen- und Saldenliste (SuSa) is the list of account balances produced from your bookkeeping. It is the raw material for the annual accounts — mapping it to the HGB captions produces the Bilanz and GuV.

How do I go from bookkeeping to the annual accounts?

Map each trial-balance account to its HGB Bilanz or GuV line, post year-end adjustments (accruals, provisions, depreciation, deferred items), and apply the presentation for your size class. Software can do the mapping and draft the statements from the uploaded trial balance.

What are the year-end deadlines?

A micro or small GmbH prepares within 6 months of the balance sheet date (§ 264 Abs. 1 HGB), the shareholders adopt within 11 months (§ 42a GmbHG), and you file within 12 months (§ 325 HGB).
