New Mandatory Receipt Reporting in Hungary from September 2026 – What Businesses Need to Know
Last updated: 26 August 2026
Hungary is taking another significant step towards digital tax administration.
From 1 September 2026, a new mandatory receipt data reporting obligation will come into force towards the Hungarian National Tax and Customs Administration, or NAV. The new rule primarily affects traditional handwritten receipts and certain computer-generated receipts.
The aim of the change is to ensure that data relating to transactions which have not previously been transmitted automatically into NAV’s digital systems will also be reported in a structured format.
The obligation applies from 1 September, but NAV will provide a transition period until 31 December 2026, during which its primary focus will be on helping businesses prepare. According to NAV’s guidance, no penalties will be imposed during this period for incorrect or missing compliance with the new reporting obligation. Sanctions may become a real risk from 1 January 2027.
What exactly is changing?
The legal framework is based on the amended provisions of Act CXXVII of 2007 on Value Added Tax, commonly referred to as the Hungarian VAT Act.
From 1 September 2026, data must be reported in relation to, among others:
- handwritten receipts issued from traditional receipt books;
- computer-generated receipts;
- documents modifying or cancelling such receipts.
This does not mean that every receipt issued in Hungary must be reported manually.
Where receipt data is already transmitted automatically to NAV — for example through a compliant cash register or e-cash register system — no separate manual reporting is required.
The new rule therefore does not introduce a new tax, nor does it change VAT rates. The essential change is that data relating to affected receipts must also be transmitted electronically to NAV after issuance.
Why is the new system necessary?
Hungarian tax administration has become increasingly digital in recent years.
The Online Invoice system, online cash registers, eVAT and e-cash registers already transmit significant amounts of transaction data automatically to NAV.
Traditional handwritten receipts and certain computer-generated receipts, however, have so far remained partly outside this data flow.
One of the aims of the new system is therefore to give NAV a more complete picture of economic transactions documented by receipts.
Another major objective is automation. The more data is available in a structured electronic format, the easier it becomes to support:
- tax returns;
- accounting processes;
- data reconciliation;
- the identification of discrepancies;
- NAV’s risk analysis.
In the longer term, Hungary is moving towards a system in which fewer and fewer tax-relevant transactions remain exclusively paper-based.
How does this fit into European tax trends?
It is important to clarify that the Hungarian receipt reporting system is not a directly applicable EU obligation.
The new rule is a Hungarian national requirement.
However, it closely follows the broader European trend towards the digitalisation of VAT systems and the increased use of electronic transaction data.
On 11 March 2025, the European Union adopted the VAT in the Digital Age, or ViDA, reform package.
One of the central elements of ViDA is the wider introduction of digital reporting and electronic invoicing. From 1 July 2030, major new digital reporting obligations will apply to cross-border B2B transactions.
The Hungarian receipt reporting system and ViDA are therefore not the same system, but the underlying direction is similar:
tax authorities are increasingly building their control and reporting systems around structured, electronically processable transaction data.
Hungary already operates one of the most highly digitalised tax administration systems within the EU.
How must the reporting obligation be fulfilled?
As a general rule, data relating to affected receipts must be reported within three calendar days following issuance.
It is important that the deadline is based on calendar days, not business days.
According to NAV’s example, data relating to a receipt issued on a Friday must be reported no later than midnight on the following Monday.
The reporting logic differs from the Online Invoice system.
Businesses are generally not required to submit each receipt individually. Instead, daily aggregated data must be reported.
The data must be properly separated according to factors such as:
- VAT category;
- receipt serial number range;
- currency;
- type of document.
Relevant VAT categories may include, for example, the 0%, 5%, 18% and 27% VAT rates, as well as VAT exemption and other special categories.
What data must be reported?
According to current NAV guidance, the reporting dataset may include:
- the issuer’s tax number;
- name and address;
- the date of issue of the receipts;
- the aggregated gross consideration;
- the applicable VAT categories;
- the number of receipts;
- the starting serial number of the relevant range.
Where receipts are issued in a foreign currency, the currency and the applicable exchange rate are also relevant.
This means that businesses must do more than simply know their daily turnover. Receipt numbers, VAT categories and foreign currency data must also be accurately traceable.
What if several receipt books or currencies are used?
If a business uses several receipt books or different serial number ranges, the data cannot necessarily be combined into one report.
Different serial number ranges must be handled separately.
The same applies to different currencies.
For example, if a business issues receipts in both Hungarian forints and euros on the same day, the data must be treated separately.
This may be particularly relevant for businesses operating in tourism, hospitality, international services or serving foreign customers.
What happens with cancelled or corrected receipts?
The new rules do not apply only to original receipts.
Documents that modify or cancel receipts must also be taken into account.
These must be handled separately and reported with the appropriate sign and VAT category.
This is important because simply reporting the net daily turnover is not sufficient. The system must also track whether a previously issued transaction has later been modified or cancelled.
Can incorrect reporting be corrected?
Yes.
NAV allows previously submitted data to be corrected.
An incorrect report can be resubmitted with the correct data, and the corrected version replaces the previous one.
Particular attention should be paid to the starting receipt serial number. If this was reported incorrectly, the original submission must be invalidated and a new report must be submitted.
How can businesses fulfil the obligation?
Businesses can choose between several solutions.
- Manual entry
Where only a small number of receipts are issued, the data can be entered manually through the KOBAK/Cash Register Portal web interface.
This may be suitable primarily for businesses issuing only a limited number of handwritten receipts.
- M2M data connection
Businesses with a larger transaction volume can use a machine-to-machine, or M2M, connection.
In this case, the company’s POS, ERP, accounting or other IT system can communicate automatically with NAV’s system.
This can significantly reduce manual administration and the risk of error.
- E-cash register
Businesses may also use an e-cash register solution.
Where the system automatically transmits the necessary data to NAV, no separate manual reporting is required for the relevant transactions.
What internal methodology should businesses establish?
Businesses should not treat the new obligation as simply another administrative task.
It is advisable to establish a separate internal compliance process.
The first step should be to determine:
- what types of receipts the business issues;
- which data is already transmitted automatically to NAV;
- what receipt books and serial number ranges are used;
- which VAT categories apply;
- whether receipts are issued in foreign currencies.
Businesses should then determine:
- who collects the data;
- who verifies it;
- who submits the report;
- how the information reaches the accounting department.
This is particularly important for foreign-owned Hungarian companies.
Management should not automatically assume that every NAV reporting obligation is handled by the accountant. Responsibilities should be agreed clearly in advance with the accountant or other service provider.
What should businesses do now?
The period between September and December 2026 should be treated as a genuine transition period.
Businesses should:
- determine whether the new obligation applies to them;
- select the appropriate reporting method;
- verify the necessary NAV access rights;
- review receipt serial numbers and VAT categories;
- assign internal responsibility;
- establish a correction procedure;
- and, in the case of higher transaction volumes, discuss M2M integration with their software provider.
The transition period should not be interpreted as a postponement.
The rule applies from 1 September 2026; NAV is simply allowing a sanction-free adjustment period until the end of the year.
Part of a wider digital transformation
The new receipt reporting obligation is not an isolated reform.
The Online Invoice system, eVAT, e-cash registers and the new receipt reporting requirement together form an increasingly interconnected digital tax environment.
The long-term direction is clear:
Hungarian tax compliance is becoming increasingly data-driven, automated and transaction-based.
For businesses, this means that the quality and structure of the data processed by invoicing, cash register, accounting and ERP systems will become increasingly important.
