Receipt data reporting from 1 September 2026

What exactly changes

Today a substantial share of receipt data is invisible to NAV. Online cash registers have long transmitted turnover data in real time, but receipts issued by hand (from a receipt book) or generated by software have fallen outside that net.

From 1 September 2026 that ends. Affected businesses must report data on the receipts they issue. The reporting is not real-time in the cash register sense: receipts are transmitted in aggregate, broken down by tax rate, within a few calendar days of issue.

The legal framework is set by NGM Decree 8/2025 (31 March). The practical details — the exact data content and the technical method of submission — are found in NAV's guidance and in the decree's annexes, and are worth re-checking as the introduction approaches.

Who is affected — and who is not

You are affected if you have a receipt-issuing obligation and do not discharge it through an online cash register — that is, you use a printed receipt book or a software receipt program. Most smaller service providers fall here: hairdressers, beauticians, mechanics, private tutors, small catering outlets, market traders.

You are not directly affected if you issue only invoices rather than receipts — invoice data has been transmitted through the online invoicing system for years. Many service and B2B businesses therefore encounter no change at all.

Users of online cash registers are in a transitional position. Existing machines continue reporting, and the legislation allows them a longer, multi-year migration to the new system — under current rules, into the early part of the next decade. Cash register operators therefore have no immediate task in September 2026, but must plan for the longer transition.

The free eCash Register app

NAV provides a free application for meeting the obligation. In practice it is a mobile or desktop application that produces receipts and performs the data reporting automatically.

The absence of a fee matters. Acquiring and running a traditional online cash register — servicing, the fiscal control unit, data transmission charges — runs to a six-figure forint sum annually for a small business. The eCash Register replaces this, requiring only an internet connection and a suitable device.

Businesses with more complex operations — barcode scanning, stock control, multiple tills — may still be better served by commercial solutions. The free application is optimised for low-volume, simple operation.

Why it is being introduced

The purpose is explicitly the reduction of the shadow economy. After online invoicing made invoiced turnover transparent, receipt-based trade — typically cash, typically to private individuals — was left as the last grey area.

The reporting obligation does not by itself raise anyone's tax. What it changes is risk. Undeclared cash revenue was effectively invisible; from now on, every receipt issued appears in NAV's risk analysis. Anomalies — revenue disproportionately low relative to purchases, for instance — can be filtered automatically.

From the entrepreneur's perspective the conclusion is simple. For those already compliant, the change is an administrative burden and nothing more. For those who are not, exposure rises substantially.

How to prepare over the summer

1. Establish whether you are affected. If you issue receipts and have no online cash register, you are. If you issue only invoices, you are not. If in doubt, your accountant can settle it in a minute.

2. Choose your tool. The free eCash Register or a commercial solution. The decision turns on daily receipt volume, stock control needs, and the reliability of your internet connection.

3. Register and test early. Reporting requires electronic identification. If you do not yet have working access — or, as a foreign national, need to obtain Ügyfélkapu+ — start there, because it requires appearing in person.

4. Train whoever stands at the till. The system works if the owner understands it; it works well if the person actually issuing the receipt understands it too.

The September deadline is closer than it looks in July. Experience with such introductions is that the final fortnight congests. Preparing in August is more comfortable than preparing at the end of August.

Receipt or invoice? Where the line falls

Because the obligation attaches only to those issuing receipts, it is worth clarifying which document is due when. The rule is simpler than it appears.

An invoice must be issued if the customer requests one, or if the customer is a taxable person or not a natural person. The invoice identifies the buyer, carrying their name, address and tax number.

A receipt suffices where the customer is a natural person, does not request an invoice, and pays in cash (or an equivalent instrument) below the statutory threshold. A receipt does not identify the buyer.

This produces a common but mistaken reflex: "then I shall simply invoice everything and escape the reporting obligation." In principle this is possible; in practice the receipt-issuing obligation cannot be sidestepped at will. Where the law prescribes a receipt and you issue an invoice instead, you must process the customer's personal data — a data protection and administrative burden. Asking every client in a hair salon for their home address is not a simplification.

The reverse does not work either. Those who invoice today cannot "switch" to receipts to avoid the online invoicing system. Both data types reach NAV; only the channel differs.

What this means for cash-based businesses

The burden is not evenly distributed. A consultant issuing five invoices a month for bank transfer will scarcely notice. A snack bar issuing fifty receipts a day will see its operation change materially.

Those affected should plan for three things. Hardware is the least of them: a reliable smartphone or tablet suffices for the free application. The internet connection is more critical — for a market trader or a mobile service provider, mobile network quality determines how smoothly the day runs. The legislation accommodates temporary loss of connectivity, but routine offline operation is not sustainable.

The third and most underestimated item is time. In the first weeks, issuing a receipt will be slower than tearing a page from a book. The gap closes with practice, but during the introduction week queues lengthen. This is precisely why starting in August, at lower volumes, beats starting in September.

A reassuring closing observation: the reporting obligation introduces no new tax, no new rate and no new return. For anyone who has kept their receipt book properly and declared their revenue, the numbers do not change — only the route those numbers take to NAV becomes shorter.
