Cash register knowledge, backed by sources.

From an open cash box to an electronic till: learn the basics and explore the explanation with links to original sources.

Three terms, three different tasks.

TSE, receipt and register notification are often mentioned together. When talking to your provider, it helps to distinguish their functions.

Current law

TSE

The technical security system protects digital records against undetected changes. For a covered electronic register system, it is one part of the requirements. Ask which TSE is used and how its operation is monitored in that particular system.

Receipts

For covered transactions, a receipt is issued and made available in direct connection with the transaction. Today, it may be provided on paper or, with the recipient's consent, electronically in a standardised data format. These conditions remain important for digital solutions too.

Register notification

Technically securing the records is not the same as notifying the tax office. Explicitly ask who takes care of any required notification. Having a TSE does not answer this organisational question.

Understanding the 2028 cash-register proposal: four terms with different meanings

Total turnover, cash turnover, payment method and cash-register system in the government draft: recognise common mix-ups and prepare information correctly.

What is planned for 2028
  1. Total turnover and reports
    For total turnover, the draft refers to section 19(2), sentence 1 UStG; the appropriate classification must be checked separately.

  2. Cash turnover and cash acceptance
    The proposed exemption combines an amount with the condition that cash is accepted.

  3. Card terminal and cash register
    The technical inventory must therefore cover the systems and processes actually used.

Practical recommendations

Questions for your discussion

Ask to see the three tasks demonstrated on your own register. Gather existing evidence and note which contact can explain unresolved points.

Understand register terminology
  1. Which registers, apps and connected payment systems do you use at which locations?

  2. Keep the provider, model, serial number, TSE documents, acquisition date and existing notifications together where you can find them.

  3. Ask for a demonstration of receipt provision, cancellations and data export on your own register.

Frequently asked questions.

Do I need to buy a new register now?

The plans for 2028 do not create a blanket obligation to buy a register today. What matters is the rules already in force, your business processes and whether your existing register is suitable. Our check helps you separate these questions.

Has the cash-register obligation for 2028 already been enacted?

On 23 September 2026, the Federal Cabinet approved a government draft. This is a step in the legislative process, not yet an enacted law. Changes remain possible.

Can I use the check without signing up?

Yes. You receive guidance directly on the page. Your answers stay in your browser during the check. They are not copied into a contact form.

Can I get binding legal advice here?

No. The check provides guidance on selected cash-register rules based on your answers. For special cases or unclear information, it shows which questions to discuss with your tax adviser.
