Mandatory Fuel Product Naming Rules: Government Decree 80/2026

Hungary’s Government Decree 80/2026 introduces a mandatory requirement from 1 September 2026 for fuel stations to append standardized codes (e.g., #NB#, #PB#) at the end of fuel item names on receipts and invoices to ensure accurate real-time reporting. The codes must appear as the final element in both cash register and invoicing system fields, with non-compliance potentially leading to rejected data submissions and increased audit risk.

Under Government Decree 80/2026 (IV. 2.), fuel stations must append specific codes (#NB#, #PB#, #NG#, #PG#) to the end of fuel item names on receipts and invoices to ensure proper data reporting. This is a part of a Hungary ’s broader framework from September first 2026. The code must be included as a closing string in both cash register logs (field NA in ITL) and invoicing systems (lineDescription), with no characters allowed after it. This is a mandatory reporting requirement, ensuring correct classification of fuel types and compliance with real-time reporting rules—non-compliance may lead to rejected data and increased audit risk.

Mandatory codes:

• Regular gasoline → #NB#
• Premium gasoline → #PB#
• Regular diesel → #NG#
• Premium diesel → #PG#

These codes must be appended to the item name (“fantasy name”) of the fuel and serve as a standardized identifier for reporting purposes. If multiple fuel types exist within the same category, the same code applies.

Cash Register Reporting (Online Fiscal Systems)

For receipts, simplified invoices, and fuel card slips issued via online cash registers, the code must be:

• Added in the item name field (NA) within the ITL section of the log/XML file
• Positioned at the end of the item name as a closing string
• No characters are allowed after the code

Example:

A space before the code is optional, but the code must always be the final element.

Invoicing Software (Online Invoice Reporting)

For invoices issued via invoicing software:

• The code must be included in the line Description field of each invoice item
• It must follow the same rule: appended after the product name as a closing character string

Important Compliance Insight

This requirement ensures consistent classification and automated reporting of fuel sales to the tax authority. It is not merely formatting, but a mandatory data element for compliance with Hungarian real-time reporting obligations.

Failure to correctly structure the item name (including the closing code) may lead to:

• Incorrect or rejected data submissions
• Increased audit risk due to misclassification of fuel types
