Technical guide for NAV Online Invoice data reporting login
From 1 July 2020, you are required to report data of all transactions between domestic taxpayers to NAV (NTCA, National Tax and Customs Administration of Hungary), regardless of the amount of VAT. Therefore you are required to report all invoices issued for enterprises.
The obligation to report invoices online is also valid for taxpayers who fall under the reverse charge mechanism and/or issue invoices regarding transactions that are exempt from VAT. The latest regulation is therefore valid for everyone, with the exception of:
- issuing invoices to entities in foreign countries only
- issuing invoices to individuals (natural persons) only
From 1 January 2021, all invoices with a domestic place of performance shall be reported – this also applies to invoices where the buyer is a natural person.
We show you how to log in to the NAV Online Invoice System via Client Gateway (Ügyfélkapu) and connect your Számlázz.hu or MostSzámlázz account with the NAV system.
Watch our short video to see how to connect the two systems:
English subtitles are available, just turn on subtitles on YouTube
Or read our step by step introduction with screenshots and read the instructions!
STEP 0/1 – Do you have governmental “Client Gateway” (Ügyfélkapu) access?
If you already have access, you may proceed to the next section (Step 1). However, if you do not have access yet, you need to request a “Client Gateway” (Ügyfélkapu) identifier. Any natural person can do this:
- If your personal ID card was issued after 1 January 2016, you can request the identifier at the “Client Gate” (Ügyfélkapu) registration page by clicking on the “E-identifier” (E-személyi) button. Please click here to find the instructions for e-registration.
- If you are not eligible, you may request the client gate identifier personally in any office for government-issued documents (okmányiroda), government administration window (kormányablak), NAV central customer services, certain postal customer services or foreign missions.
If you request the client identifier (ügyfélazonosító), you get the identifier immediately. You just need to activate it.
STEP 0/2 – Activating the client gateway (ügyfélkapu)
After you have registered successfully, you will receive a single-use code for the first login sent by the system to the email address provided during the registration. You may use the single-use code received via email within 3 days after sending it. Click on the link sent in the email, and fill in the form on the “Activation” (Aktiválás) page. Click here for instructions.
If you have registered online with an electronic personal identification card (which you can do if your personal identification card was issued after 1 January 2016), once you have registered successfully, you may login to the space after about an hour using the password provided during registration.
The list that appears on this screen (Taxpayer-user relations) includes the taxpayers to whom you have the right of active representation. This means you will only encounter this screen if you have an active connection with multiple taxpayers. In this case, please select the appropriate one: click on the name of the taxpayer or the “Open” button to continue. If you do not have more active connections, jump to the next step.
The required fields are marked on the Contact information form. The taxpayer’s information is filled in automatically (check if all information is correct), except for the contact e-mail address and telephone number. Please, fill in these and if you’d like to change anything (e.g. the contact language, which is set to Hungarian by default), you can do so here.
On the main page of the NAV Online Invoice system, select the “Users” menu item in the top menu bar. The red bar shows the following error message: “Settings for data are incomplete”, but don’t be scared! The login was successful, but in order to connect the NAV Online Invoice system with your Számlázz.hu account, you also need to create a “technical user”. We will show you how to do this in the next steps.
Sign in your Számlázz.hu account account via Beállítások/Fiók beállításai/NAV online adatkapcsolat (Settings/Account settings/NAV online data connection). Copy the required data into the empty fields (4 data will be required): the technical user’s name created in the NAV system, the technical user’s password, the XML Signature Key and XML Exchange Key. ATTENTION: If you have accidentally completed the login in to the NAV test system, you cannot create a connection using the above-mentioned information. The creation of the connection can only be successful if you log in to the live NAV system!
