What is Real Time Invoice Reporting?


It is a new obligation proposed by the Hungarian tax authority (HU TA/NAV) for submitting all the invoice reports with the main goal of reducing tax avoidance and whitening the economy. So far it has proven to be effective, since during the last 2 years share of the ‘grey economy’ in Hungary has decreased from 27% to 21-22%.

The introduction of RTIR has started 2 years ago, with a gradual rollout:

  • Jul 1 2018: obligation of reporting of all invoices above value of 100k HUF
  • Jul 1 2020: obligation of reporting all B2B invoices
  • Jan 1 2021: extended obligation of reporting all B2C invoices

Connection with the Hungarian tax authority (HU TA) is purely online – there is no possibility of manual/offline reporting. Each user will have to register at the HU TA system and create a technical user in order to send data to the online platform. The HU TA will return a status of each report for invoices sent. The VAT data report will take place immediately and electronically, without any human intervention.

Main RTIR developments for 2021

  • All resident taxpayers must use XML version 3.0 in their online invoicing reports.
  • Businesses registered in Hungary for VAT purposes will have to report the invoices they issue to individuals (B2C) as well.
  • Businesses must declare export invoices, both intra- and extra-EU.


To whom new Hungarian invoicing rules may concern?


In short, the RTIR obligation will affect all businesses that possess a Hungarian VAT ID. Exporters have an obligation to get a HU VAT ID if their yearly turnover exceeds 35k EUR. For the detailed scenarios when to report and when not to report find the table below:






As mentioned above, the obligation to report B2C invoices – the part impacting e-commerce exporters the most – is valid from Jan 1 2021.

IMPORTANT: The Ministry of Finance has granted a sanction-free three months grace period from 1 January to 31 March 2021 allowing businesses more time to comply with these new reporting obligations. This will also help with the transition from the current v2.0 XSD real-time reporting to the latest v3.0 XSD, which will be mandatory from 1 April 2021. For now, it is uncertain if there will be a requirement to retroactively report the transactions not declared during the grace period.


EU One Stop Shop (OSS) solves it all in the long-run

There will be another important change from 2021: the European Commission amended VAT regulations allowing Member States to prepare themselves for the introduction of the One Stop Shop (OSS); set to launch on 1 July 2021. The OSS aims to simplify submitting VAT returns (also by not being obliged to register in every EU country) and paying the correct country specific VAT for online retailers in the various Member States where they trade.

Tip: bearing in mind the upcoming EU OSS solution, and its launch on Jul 1, multi-country exporters basically need to ‘cover’ just the 3-month period of Q2 in 2021 with the Hungarian RTIR.



We have brought you 3 different solutions to comply with the RTIR in Hungary – from a low-entry self-service system to a tailored solution. For the DIY types there is a step-by-step guide as a 3rd option. 


Solution #1 – the self-service system


Balázs Ángyán, CEO of Számlá, the market leading online accounting SaaS solution in Hungary with 460k active clients introduced their own API-based solution for RTIR: Invoice Agent



Invoice agent is a non-browser-based interface of the Számlá system, that receives XML messages and depending on the received information. It can create invoices, reverse invoices, register credit entries, query invoice pdf files, query invoice xml files, etc. With API documentation easy to connect with your webshop, it results in significant cost savings, plus there are no errors, therefore you do not need to make corrections subsequently. Through API you only need to provide the billing data and with that information Számlá will create an invoice for you that complies with the regulations, send it to NAV and forward the data in XML and PDF to the webshop.

Important note: with Invoice Agent solution, the invoice is being issued by Számlá as the primary system, the invoice number being generated by Szá In case you need to connect it to your ERP system – and maintain data integrity of invoices across all systems -, further integration is needed.

Tip: Shoptet is currently working on the integration of Számlá’s Invoice Agent. According to their statement it will be available on their app store (“doplnky”) in Q1 2021.


Third-party invoicing and self-invoicing is recommended for those who have too many vendors, and the invoices issued to the company are filled in incorrectly too often, or who employ agents and pay them commissions on a monthly basis.


Solution #2 – the tailored solution

Lilla Németh, Director of tax services at RSM introduced their company’s online invoice reporting solution. Their cloud-based platform, Connectax solutions and software modules are easily and quickly connectable to partners’ current ERP, accounting and invoicing systems.


In case you maintain your current invoicing program, RSM advise you how to adjust your currently available XML file of your sales invoices, thus you will be able to fulfil the HU TA requirements. RSM has also an IT software solution: you send them the proper XML file and their software will communicate directly with HU TA, save the feedback and let you know the status of the online reporting.

The main difference compared to Számlá’s solution is that in RSM’s Connectax case your ERP remains the primary system for issuing the invoice. Connectax serves as an online connector between your ERP and the HU TA.

More detailed information about Connectax and its features can be found on RSM’s EN website.


Solution #3 – for the DIY types

Unfortunately there is no guide by the Hungarian tax authority in English but thanks to Számlá’s comprehensive step-by-step guide here you can develop your own solution in just 15 steps.
