What businesses should know about retention

Books, records, receipts, and relevant business papers generally need to be kept for seven years

Invoices, bank documents, bank statements, and business emails can be tax-relevant

Electronic retention needs to remain complete, orderly, content-identical, and readable

Which documents are affected

Alongside books and records, documents such as invoices, bank receipts, bank statements, business papers, and other records can be subject to retention duties when they are relevant for taxes and duties.

Think about outgoing and incoming invoices together

Connect bank documents and invoices transparently

Avoid scattered business document storage

Electronic archiving

Digital retention is possible when documents can be reproduced completely, orderly, content-identically, and true to the original. A simple copy to an arbitrary storage device is not automatically enough.

Store digital documents readably and findably

Keep order and original fidelity in mind

Plan archiving as part of the invoice workflow

Deadlines and special cases

Accounting documents and invoices are generally subject to a seven-year retention period. Depending on special rules, longer periods can apply, for example for certain property documents or OSS-related services.

Know the seven-year period as the baseline

Check special retention periods for specific cases

Keep documents longer when proceedings are pending
