Why do I need fiscalization?
Explained in plain language: what fiscalization actually is, who it applies to, what the law asks of you — and what happens when the tax office turns up unannounced. No legalese, a ten-minute read.
Fiscalization means your POS can no longer forget anything.
Every sale you ring up on an electronic POS is signed electronically by a certified security module at that very moment and logged without gaps. Afterwards no transaction can be deleted, altered or quietly made to disappear without it showing. That is exactly the point: the legislator wants till manipulation to become technically impossible. For you as a merchant it means two things above all — your POS has to meet specific technical requirements, and you must be able to hand the tax office a clean data export at any time, on request.
Does this apply to me?
One test settles it: do you record your sales with an electronic system? If yes, the rules apply — regardless of industry, size or legal form. There is no small-business exemption.
Yes — this applies to you
If any one of these is true, the duties are yours.
- Cash register, PC POS, tablet or app-based POS
- A card terminal that also acts as a POS
- Any industry — hospitality, retail, bakery, butcher, hairdresser, kiosk, food truck, market stall, trades with cash sales
- Scales with register functionality, as well as taximeters and odometers
- Also rented and leased systems — not just purchased ones
- Any legal form, any size — from sole trader to GmbH
No — only in this case
There is exactly one exception — and it is less comfortable than it sounds.
- Only an open cash drawer — a cash box, a handwritten cash book, no electronic system. Germany currently has no general obligation to use an electronic register.
- But: individual recording, daily cash-count reconciliation and a GoBD-compliant cash book still apply — usually more work and more audit risk than a proper POS.
- And: an obligation to use an electronic register above €100,000 annual turnover has been announced for 2027.
What the law actually requires of you.
At its core it comes down to six duties. Meet them and you are on the safe side.
1 · Certified TSE
Every transaction must be signed by a BSI-certified technical security module — either built into the device or as a cloud TSE. Without a TSE your records are not compliant, even if you do everything else right.
2 · Receipt obligation
A receipt must be available for every transaction — paper, e-mail or QR code. The customer does not have to take it, but you have to offer it. The receipt carries the signature counter, check value, serial numbers and the time of the transaction.
3 · Individual recording
Every single transaction is recorded individually, completely, correctly, promptly and unalterably. Daily totals alone are not enough — an auditor wants to be able to see each receipt.
4 · DSFinV-K export
During an inspection you must be able to hand over your POS data in the nationwide standard format, together with the TSE log files. On demand, with no lead time. If you first have to call your POS vendor, you have a problem.
5 · Reporting to the tax office
Since 2025 electronic recording systems must be reported via ELSTER. Systems acquired before 1 July 2025 had to be reported by 31 July 2025; anything acquired after that within one month. Rented and leased systems count too, and decommissioning must also be reported.
6 · Retention & documentation
POS data must be kept in an audit-proof way for ten years — including long after you have switched systems. On top of that you need process documentation that explains to a knowledgeable third party how your POS works.
The key dates at a glance.
What has applied since when — and what is still coming.
KassenSichV takes effect
The TSE requirement and the receipt obligation begin. Existing tills were initially covered by transition and non-objection periods.
No transition periods left
Since then even legacy tills that cannot be upgraded may no longer be operated without a TSE. Ringing up sales without a TSE today means your records are not compliant.
Reporting via ELSTER
Existing systems had to be reported by 31 July 2025, newly acquired systems within one month. Reporting runs electronically through Mein ELSTER or your software.
Mandatory electronic register
The coalition agreement foresees an obligation to use an electronic POS above €100,000 annual turnover, with the receipt obligation dropped in return. No draft law exists yet — the details are still open.
What happens when the tax office shows up?
The cash register inspection under § 146b AO is unannounced. The inspector arrives during business hours, identifies themselves and may look into your POS straight away — no advance notice, no appointment.
What gets checked
Is an active, certified TSE in use? Is every transaction signed? Does the customer get a receipt? Can the DSFinV-K export be produced immediately? And does your process documentation match what actually happens at the counter?
What a violation costs
Under § 379 AO fines of up to €25,000 per violation may be imposed — regardless of whether any tax was actually evaded. A missing or non-functioning TSE is enough on its own.
The real risk
If your records are not compliant, the tax office may estimate your turnover. Such upward estimates quickly reach five-figure sums, are hard to argue against — and the inspection can turn directly into a full tax audit.
Common misconceptions.
Things we hear again and again in sales conversations — and what actually applies.
"I hardly take any cash, so this doesn't affect me."
What matters is not how much cash passes through your hands, but that you use an electronic system to record your sales. A largely card-based business with an electronic POS falls under the rules just the same.
"My till is from 2019, it's grandfathered in."
It was — but the transition and non-objection periods have expired. Since 1 January 2023, even legacy systems that cannot be upgraded may no longer be operated without a TSE. There is no permanent grandfathering.
"My tax advisor takes care of that."
Your tax advisor books your figures and advises you — but they can neither fit a TSE into your device nor make sure your POS signs every receipt. Responsibility for compliant record-keeping sits with the business owner, not the advisor.
"I have a TSE, so I'm done."
The TSE is the technical core, but only one of several duties. Receipts, individual recording, the DSFinV-K export, the ELSTER report, ten-year retention and process documentation come on top. In practice, inspections fail more often over a missing export than over the TSE.
"A tablet or phone isn't really a till."
It is — as soon as you record sales with it, it is an electronic recording system and needs a TSE. The form factor is irrelevant; the function decides.
"When I switch systems I can just scrap the old till."
No. The old till's data must remain readable and analysable for the full ten-year retention period, and decommissioning must be reported to the tax office. Always secure the DSFinV-K export and the TSE data before switching.
"If I don't report it, nobody will notice."
There is indeed no separate fine attached to the report under § 146a(4) AO — but a missing report is immediately obvious during an inspection and draws the inspector's attention exactly where you least want it.
So who does all of this?
With FiskalPRO, fiscalization is not an add-on module you have to administer yourself — it is a managed service. The certified TSE sits inside the device, every transaction is signed automatically, the receipt carries all mandatory details, the DSFinV-K export is one click away, the data is archived audit-proof — and we support you with the ELSTER report. When the rules change, we roll that out centrally. Nothing for you to retrofit, nothing for you to read up on.
