In short and in plain language
Bank statements sit on the shelf, bills lie on the table. When you need something, the search begins. The article shows how to scan and sort your paperwork.
Scanning saves a sheet of paper as a picture on your computer. Good file names and fixed folders help you find things. A fixed routine helps too.
The article also explains which papers you should keep after scanning.
A backup is important. A backup is a copy of your data in another place. Also check that you can get the copy back.
We set this up with you at your home.
The folder with the bank statements sits on the shelf, the builder's invoice has been on the kitchen table since spring, and as soon as the tax return comes round the search starts all over again. On average, every person in Germany keeps 7.7 ring binders of private paperwork at home (Bitkom), and 22 per cent have ten or more (Bitkom). At the same time almost half already scan or photograph part of it: 47 per cent, yet only 19 per cent do so regularly (Bitkom). That gap is where the real problem lives. Some documents sit digitally somewhere, some sit on paper somewhere, and when it matters you find neither. This guide describes a run-through you can start over a weekend and then keep up in ten minutes a week: capture, name, file with a retention date, back up. It also explains what may genuinely go after scanning, which deadlines apply, and why the backup copy is the point at which most filing systems quietly fail - 33 per cent of private computer and smartphone users make no backups at all (Bitkom).
Key takeaways
- German households keep 7.7 ring binders per person on average, and 22 per cent have ten or more (Bitkom) - so the effort rarely pays off for a single sheet, but it does for one proper run-through.
- 47 per cent digitise part of their paperwork, but only 19 per cent do it regularly (Bitkom); the difference between those two groups is not about equipment, it is about routine.
- As a baseline, the official model concept for replacement scanning names 300 dpi, PDF/A-2b as the target format and 24 bit colour depth (BSI).
- Retention periods do not start on the invoice date but at the end of the calendar year (gesetze-im-internet.de) - which stretches every deadline by up to twelve months.
- 33 per cent make no backups at all, and only 18 per cent know how to restore one (Bitkom) - without that step, digital filing is less protected than the folder on the shelf.
How much paper is actually in the house
The starting point is surprisingly well measured. Every citizen owns 7.7 ring binders of invoices, contracts and similar documents on average (Bitkom), and 22 per cent of respondents keep ten or more of them at home (Bitkom). The figures come from a representative survey of 1,004 people aged 16 and over, so they are a projection onto the population rather than a feeling. Once you picture that volume, it becomes clear why so many digitising attempts collapse after two hours: they start in the middle, with whichever folder happens to be on top, and without any decision about what should exist at the end. A run-through that holds therefore starts not at the scanner but with a sort by topic and one question per pile: does this sheet need to be kept, and if so, for how long. Answering that first halves the volume before the first page ever reaches the glass. For records that only ever existed digitally - logins, contracts, mailboxes - the same look from the other side pays off (sorting out your digital legacy and online accounts).
The second look goes to the inflow. Statistically, every person in Germany consumes 190 kilograms of paper, board and cardboard a year (Umweltbundesamt); private households alone account for roughly 105 kilograms per head (Umweltbundesamt). That is the volume any filing system runs into again each year, and it explains why a one-off effort achieves nothing if everything afterwards lands back on the kitchen table. A third figure defuses the most common worry about clearing out: the waste paper recovery rate stands at 78.2 per cent (Umweltbundesamt), so the vast majority of paper goes back into the cycle. What leaves the folder is not lost material but raw material. The real question when clearing out is therefore never the environment but the evidence: can I still prove later what this sheet says. What that chain of evidence looks like digitally is covered further down - and how to build the backup around it is set out in our home data backup service.
Digitising means sorting, not discarding
Who already digitises - and with what
47 per cent of the population scan or photograph some of the paper documents they want to keep; 19 per cent do so regularly and 28 per cent now and then (Bitkom). That split is the most interesting figure in the whole subject, because it describes two entirely different states. People who digitise regularly have an archive that can be searched. People who digitise now and then have a folder full of image files named IMG_4821 and find just as little in it as in the paper pile - only faster. The difference is not created by the device but by three habits: a fixed location, a fixed naming scheme, a fixed appointment. Anyone who has ever sorted photos along those lines knows the mechanism (getting your phone photo chaos under control); with documents it is identical, only the search criteria have different names.
- 69 per cent digitise by taking a photo, 61 per cent use a printer or scanner (Bitkom) - the phone has long been the most widespread capture device in the home.
- Only 28 per cent of those who digitise use dedicated apps (Bitkom) that straighten the page, crop it and save it as a PDF.
- 17 per cent still file their tax return on paper (Bitkom) - in dealings with the authorities, digital documents are now the normal case.
- Among people aged 65 and over the figure is 43 per cent, among those aged 30 to 49 it is 6 per cent (Bitkom); the gap shows where support achieves the most.
- 47 per cent digitise at all, and 19 per cent of the population do so regularly (Bitkom) - the entire benefit of the subject sits between those two groups.
Phone camera
The most widespread route: 69 per cent photograph their documents (Bitkom). Fast and always to hand, but without post-processing you end up with skewed, colour-cast pictures rather than searchable documents. If you capture a lot in one go, keep an eye on the battery first (what actually helps phone battery life).
Scanning app
It detects the edges of the page, corrects the perspective, puts several pages into one PDF file and reads the text along the way. Only about a quarter currently use exactly that (Bitkom) - the biggest single lever in the whole process, because it turns a picture into a searchable document.
Flatbed on the device
61 per cent use a printer or scanner (Bitkom). The glass plate is the right choice for delicate, folded or double-sided sheets and for anything that needs to come out straight and sharp to the edge.
Feeder for stacks
Multifunction devices with a feeder take a whole stack in one go and turn them into a single file. For the first big run-through, that is the difference between an afternoon and a weekend.
Digital originals
Invoices, statements and official notices are already available as PDFs in many portals. Those files beat any scan because they contain text rather than pixels - they simply need downloading regularly, before the access expires.
Text recognition
Only text recognition turns a picture into a document you can search by words. It sits in many scanning apps and in most multifunction devices, and it costs nothing but a tick box in the settings.
The run-through in five steps
A filing system is not created by scanning a lot; it is created because every scan lands in the same place and gets the same kind of name. That is why preparation comes before technology. Clear a table first, build piles by topic - home, work, health, vehicle, contracts, tax - and in a first pass throw away everything that obviously proves nothing any more: advertising inserts, duplicate copies, expired quotes, manuals for devices that left the house long ago. Then comes the actual work, and it is shorter than it looks. If you are setting up the scanner anyway, the basics are on our page about setting up printers and scanners; the order below works with any device, and with a phone alone.
- Sort. Build topic piles, remove the obvious, label each pile with a slip of paper. This step determines how long the whole run-through takes.
- Capture. Scan or photograph pile by pile, multi-page matters as one file, front and back together whenever the back carries something. Name nothing in between - capture first, name afterwards.
- Name. Date, sender, keyword, always in that order. Putting the date first means the archive sorts itself chronologically.
- File. Into the folder tree you defined beforehand, with a retention date in the name or in the folder. Without a date the file can be found, but nobody later knows when it may go.
- Back up. Two copies in two places, then one check that a file can actually be pulled back out of the backup. Only this step turns files into an archive.
- Keep it up. A fixed slot once a week, ten minutes, for whatever arrives in the letterbox. Without that slot, the big run-through is undone again within six months.
The values from the official model concept
Folder tree and file names
The structure may be small, it only has to be unambiguous. What works is a tree of at most two levels: eight to twelve areas of life at the top, and the year beneath each of them. Everything else is carried by the file name, and it does that better than any deep folder hierarchy, because names can be searched and folders cannot. Start the name with the date in the form YYYY-MM-DD, and every operating system will sort the archive chronologically by itself. Sender and keyword follow, separated by hyphens, without spaces and without special characters - accented letters in file names are usually harmless nowadays but still cause trouble when moving between devices. If you are setting up phone backups in parallel, the matching approach is in backing up phone photos and choosing a backup strategy.
- Date first, in the format YYYY-MM-DD: 2026-03-14 sorts correctly, 14/03/2026 does not.
- Sender as the second field, in a short form you can keep up: utilities, health insurer, landlord, tax office.
- Keyword as the third field, as concrete as possible: annual statement, heating costs, dental work, car insurance.
- No spaces, no slashes, no colons - hyphens and underscores travel everywhere.
- Retention marker in the folder name rather than the file name, for example a subfolder 2026-keep-until-2029 holding everything that may go from 2030 onwards.
- One naming scheme for everything, not one per area of life. Change the pattern once and you will be searching two systems from then on. For the first few weeks a printed cheat sheet next to the device helps, or a session in our computer courses.
A name that still works in ten years
Deadlines: how long things have to stay
The rule of thumb for a private household is the standard limitation period, which runs for three years (gesetze-im-internet.de). Most recommendations follow it, because claims arising from purchases, works contracts and services are normally asserted within that window. Anyone running a business on the side has to think further ahead: invoices must be kept for eight years there (gesetze-im-internet.de). And both groups share the same stumbling block, which extends every invoice in your head by up to a year: the retention period does not begin on the date of the invoice but at the end of the calendar year in which the invoice was issued (gesetze-im-internet.de). People who go through their folders in January and count from the issue date routinely discard things too early. The same care pays off with payment records now that payee verification applies in payment traffic (online banking in 2026 and payee verification).
| Document | How long it should stay | Where the deadline comes from |
|---|---|---|
| Bank statements and transfer slips | at least 3 years | recommendation by the Verbraucherzentrale for private banking records (Verbraucherzentrale) |
| Builder's invoice in a private household | at least 2 years, as an owner or landlord 6 years | Verbraucherzentrale guide on retention obligations (Verbraucherzentrale) |
| Invoices in a business context | eight years | Section 14b of the Value Added Tax Act (gesetze-im-internet.de) |
| Records to be kept for tax purposes | ten, eight or six years, depending on the type | Section 147 of the Fiscal Code (gesetze-im-internet.de) |
| Patient records held by a practice | ten years after the treatment ends | Section 630f of the Civil Code (gesetze-im-internet.de) |
| Court judgments and enforcement orders | 30 years | Verbraucherzentrale guide on retention obligations (Verbraucherzentrale) |
| Proof of education and employment | until the pension statement, from 55 renewed every three years | Section 109 of Book Six of the Social Code (gesetze-im-internet.de) |
Two periods fall outside the pattern and therefore belong in a category of their own. Claims for damages arising from injury to life, body, health or liberty only become time-barred after 30 years (gesetze-im-internet.de); court judgments and enforcement orders likewise have to be kept for 30 years (Verbraucherzentrale). Anything pointing in that direction belongs in a folder that is not tidied up by year. High earners are additionally affected: where annual income exceeds 500,000 euros, receipts and records must be kept for six years (Verbraucherzentrale). How strongly the year-end start affects things is shown by a worked example from the Verbraucherzentrale: a builder's invoice dated 6 June 2022 triggers a two-year period that starts on 1 January 2023 and only ends on 31 December 2024 (Verbraucherzentrale) - turning two years into two and a half. Anyone keeping an eye on their own devices already knows this logic from another context (new access rights to smart home data from September 2026).
May the paper go afterwards?
For cases where paper is destroyed after scanning there is an official framework: Technical Guideline TR-03138 issued by the Federal Office for Information Security, known as RESISCAN. It describes how replacement scanning has to run so that the scan can take the place of the original, and it is drawn on to give substance to the state of the art that Section 7 of the E-Government Act requires for electronic file management and Section 371b of the Code of Civil Procedure requires for the evidentiary value of scanned documents (BSI). The guideline does not apply directly to private households, but it answers the decisive question: there is no blanket principle that a scan is worthless. There is a question of diligence - captured completely, stored unaltered, retrievable - and the better that diligence is documented, the more robust the scan. We build the backup side of that diligence into our data backup service.
For tax purposes the situation is clearly regulated: the Fiscal Code grades retention into ten, eight and six years depending on the type of record (gesetze-im-internet.de), and expressly permits reproduction on an image carrier. With health records the view from the other side is instructive: a practice must keep the patient file for ten years after the treatment ends (gesetze-im-internet.de) - after that nothing can be retrieved there, and your own copy is the only lasting access. Anyone using the electronic patient record should therefore know what is stored in it and what is not (setting up the electronic patient record properly). Pensions work similarly: once you turn 55, the pension information is replaced every three years by a full pension statement (gesetze-im-internet.de), and until then proof of education, employment and unemployment has to remain findable. Such records belong in the permanent category, regardless of any three-year rule.
- Certificates in the strict sense - birth, marriage and death certificates, baptism records, divorce decrees - stay on paper, and the scan is the second copy.
- Notarised contracts, land register extracts, certificates of inheritance and wills stay as originals; no scan replaces the paper here.
- School and training certificates and social insurance records stay permanently, because they are only needed decades later (Verbraucherzentrale).
- Court judgments and enforcement orders stay for 30 years (Verbraucherzentrale) - here the folder is the safe bet.
- Builder and construction records stay at least two years, and six years for owners (Verbraucherzentrale); after that the warranty situation decides.
- Everything else - bank statements, everyday invoices, confirmations, policies from earlier years - can go into the waste paper once the deadline has passed and the scan is backed up. Before an old device carrying those files leaves the house, it needs emptying (erasing data safely before selling).
The backup none of this works without
This is where the subject tips from tidiness into security, and the figures are uncomfortable. 33 per cent of people who use a computer or smartphone privately make no backups at all (Bitkom). Only 45 per cent create backups regularly, even though 20 per cent have already lost data because a backup was missing (Bitkom). The survey covered 1,186 people aged 16 and over, including 1,079 users of a private device - so the numbers describe everyday life, not a fringe group. As long as that gap exists, digitising actually makes matters worse: the folder on the shelf survives a hard disk failure without effort, a single copy on the computer does not.
Where people do back up, practice splits almost evenly: 32 per cent store backups in the cloud, 27 per cent use local media such as external hard drives or sticks (Bitkom). Both together would be the robust option, because the two routes fail for different reasons - the local medium in a flood or a burglary, the account when the password is lost. The most critical figure comes last, though: only 18 per cent know how to restore the data from a backup (Bitkom). A backup that has never been restored is an assumption with a timestamp. So plan a dry run: pull a single file back out of the backup, open it, close it - five minutes that separate a backup from the feeling of having one. If you are changing devices anyway, both jobs fit into one go (moving your data to a new device).
The retention period begins at the end of the calendar year in which the invoice was issued; Section 147 (3) of the Fiscal Code remains unaffected.
On top of durability comes a second point that paper does not know: file formats and programs age. After 30 years at the latest, existing systems end up in the attic, and for private users the Federal Office for Information Security reckons with as little as ten years (BSI). For an archive, one simple rule follows: prefer open, widely used formats - PDF for documents, JPEG or PNG for images - and avoid containers that only one particular program opens. If you encrypt, write down the method and the access somewhere a second person can reach in an emergency; an archive only one person can open is effectively absent when an estate is settled. How to organise logins and data protection in everyday life is what we practise step by step in our data protection course.
What an appointment at your home achieves
Taking stock
We look at what paper exists, what is already digital and where it sits. At the end of this step there is a list of areas of life and a decision on which piles will be captured at all - usually far fewer than feared at the outset.
Setting up
Configure the scanner or scanning app, switch on text recognition, define the target folder, write down the naming scheme. After that the route from sheet to named file is two movements long, and you have walked it once yourself.
Backup
Two copies in two places, set up and restored once. That dry run is precisely what most households are missing - only 18 per cent know how to restore a backup (Bitkom).
Deadlines and clearing out
We go through the piles with the deadlines and mark what may go from when. What stays, stays for a reason - and you keep the overview on paper so the decision remains traceable. What such an appointment costs is set out on our pricing page.
That the approach works is visible in offices: 72 per cent of German companies need less paper today than five years ago (Bitkom), and 57 per cent have reduced the number of ring binders over the same period (Bitkom) - the survey covered 602 companies with 20 or more employees. In private households the same step is usually still pending, and that is rarely down to the technology: an office has a responsibility, a fixed procedure and one place where everything lands. Those three things can be rebuilt at home in an afternoon. Anyone self-employed on the side who keeps both worlds in one archive should factor in the business retention periods from the start - we advise on that under tech help for businesses.
