Balance sheet or cash-basis accounting?

Anyone obliged to keep double-entry books prepares a balance sheet with a profit and loss account. Those who are not – many freelancers and small traders – usually determine their profit with the simpler cash-basis accounting (Einnahmen-Überschuss-Rechnung).

Thresholds in commercial and tax law

ThresholdLegal basis
Sole traders (commercial law)exempt up to 800,000 € turnover and 80,000 € net income on two consecutive balance sheet dates§ 241a HGB
Commercial businesses (tax law)obliged above 800,000 € turnover or above 80,000 € profit§ 141 AO
GmbH, UGalways obligedHGB

For newly founded businesses, the exemption under § 241a HGB already applies if the values are not exceeded on the first balance sheet date after founding.

How long do I have to keep records?

DocumentsPeriod
Books, records, annual financial statements10 years
Accounting vouchers (e.g. invoices)8 years
Commercial and business letters, other tax-relevant documents6 years

The periods are set out in § 147 (3) AO. They do not end as long as the documents are relevant to a tax whose assessment period has not yet expired.

Practical tips

  • File vouchers digitally and in order from day one
