Email Archiving in Germany: Legal Requirements You Need to Know

Email archiving is not optional for German businesses. Multiple laws and regulations mandate that companies retain business-related emails for defined periods. Failing to comply can result in fines, tax penalties, and legal disadvantages.

The Legal Framework

Three key regulations govern email archiving in Germany:

GoBD (Grundsätze zur ordnungsmäßigen Führung und Aufbewahrung von Büchern, Aufzeichnungen und Unterlagen in elektronischer Form)

The GoBD is a set of principles issued by the German Federal Ministry of Finance. It defines how businesses must handle, store, and archive electronic records, including emails. Key requirements include:

Immutability: Archived emails must not be altered after storage. The original content must be preserved exactly as received or sent.
Completeness: All tax-relevant emails must be archived without exception.
Traceability: Every action on archived data must be logged and auditable.
Machine readability: Data must remain accessible and readable throughout the retention period.

HGB § 257 (Handelsgesetzbuch)

The German Commercial Code requires merchants to retain commercial correspondence (which includes business emails) for 6 years. Accounting-related documents must be retained for 10 years.

AO § 147 (Abgabenordnung)

The German Fiscal Code mandates the retention of tax-relevant documents for 10 years. This includes any email that has tax implications, such as invoices, contracts, or financial communications.

What Counts as a Business Email?

Not every email needs to be archived. The obligation applies to emails that qualify as:

Commercial letters (offers, orders, confirmations, complaints)
Accounting records (invoices, payment confirmations, receipts)
Tax-relevant documents (anything related to tax obligations)

Internal emails that have no commercial or tax relevance are generally exempt. However, since the boundary is often unclear, many businesses choose to archive all emails to avoid compliance gaps.

Consequences of Non-Compliance

Failure to comply with archiving obligations can lead to:

Tax estimation: If records are incomplete, tax authorities may estimate your tax obligations, usually to your disadvantage.
Fines: Violations of GoBD principles can result in financial penalties.
Loss of evidence: In legal disputes, unarchived emails cannot be presented as evidence.
