Which documents to keep – and for how long?
The pile of folders keeps growing, and sooner or later you wonder: what can go, and what has to stay? Few rules apply to private households, but there are good reasons to keep some papers for a long time. This guide gives rules of thumb and shows how to stay organized digitally, without a folder system.
Rules of thumb for personal paperwork
- For life: birth, marriage and death certificates, diplomas, pension records, notarized documents, medical reports and doctors' letters.
- Until retirement: employment contracts, payslips and proof of contribution periods.
- Several years: tax returns, notices and receipts, until the tax authority can no longer change the assessment. The period depends on your country.
- While it applies: leases, insurance policies, warranty receipts – and for a while afterwards in case questions come up.
These are rules of thumb, not legal or tax advice. When in doubt, ask a tax adviser or a consumer advice service.
Scan or original?
A scan makes documents easy to find, but it does not replace every original. Keep certificates, wills, notarized contracts and documents with seals in the original. For much else, a good digital copy is enough in everyday life – decide deliberately before you throw paper away.
Organized without a folder system
In ExplainThisDoc you don't create folders. Scanning or importing is enough; search and filters bring every document back. The app sorts documents by kind, such as tax, insurance or health.
