Cégkapu (Company Gate) Hungary 2026: Registration & Login

For foreign entrepreneurs, registering a company in Hungary is only the first step. A Hungarian business must also be reachable through the official digital channels used by public authorities. One of the most important is Cégkapu (Company Gate), Hungary’s official electronic mailbox for eligible business entities.

This guide explains what the Hungarian Cégkapu (Company Gate) is, who must use it, how registration works, what foreign managing directors should check and why ignoring an electronic notice can create legal and financial risks.

What is Cégkapu (Company Gate) in Hungary?

Cégkapu—often described in English as the “Company Gate”—is the official, secure electronic mailbox used by Hungarian business organisations to receive and manage communications from authorities. “Company Gate” is an explanatory English translation, not a separate government service. Think of it as the company’s legally relevant digital postbox, not an ordinary email account.

Tax authority notices, administrative decisions, requests for missing documents and delivery confirmations may reach the business through this channel. When a document is legally served, a deadline may start running even if nobody at the company reads it.

Notifications and decisions from the Hungarian tax authority (NAV).

Requests for documents and notices from administrative bodies.

Municipal or other official electronic correspondence.

Acknowledgements related to electronic submissions.

Which businesses must use Cégkapu (Company Gate)?

The requirement applies to the relevant categories of Hungarian business organisations, including limited liability companies (Kft.), private and public companies limited by shares (Zrt./Nyrt.), limited partnerships (Bt.) and general partnerships (Kkt.).

A Hungarian Kft. owned entirely by non-Hungarian individuals or a foreign corporate shareholder is generally subject to the same obligation as a locally owned Kft. Sole traders use a different personal electronic mailbox arrangement.

When should a new company arrange Cégkapu?

Treat the official mailbox as part of the post-incorporation checklist, alongside tax registrations, bank arrangements and bookkeeping. Legal registration and the appropriate official electronic address must be coordinated without delay.

When planning company formation in Hungary, include electronic administration in the launch process instead of addressing it only after the first authority notice arrives.

How does Cégkapu (Company Gate) registration work?

Registration begins through the official government interface: https://tarhely.gov.hu/ckp-regisztracio/tajekoztato.html. The exact route depends on how the business and its representative can be verified.

Identify the person legally authorised to represent the company, or an appropriately authorised proxy.

Identify the legal entity and verify the relevant registry data.

Appoint the Cégkapu administrator (Cégkapumegbízott).

Complete automatic registration where eligible, or submit a form and supporting evidence where required.

Keep the confirmation and test that the mailbox can be accessed.

Cégkapu vs Ügyfélkapu+ vs DÁP

These systems are not interchangeable. Cégkapu is the company mailbox. Ügyfélkapu+ is a secure sign-in option for individuals. DÁP (Digital Citizenship) offers eligible individuals identification and digital public services.

Since 16 January 2025, the former username-and-password-only Ügyfélkapu sign-in was replaced by stronger identification options. Access to the company mailbox still requires a personally authenticated, authorised user.

Can a foreign managing director access Cégkapu?

Yes, provided the person has the required identification method and relevant permissions. Foreign ownership by itself does not provide automatic access. The process may depend on the director’s identity documents, registry information, residence status and eligibility for the applicable authentication service.

If the director lives abroad, plan who will administer the mailbox, who will monitor it and how official messages will reach the responsible adviser. Where appropriate, a duly authorised representative may help with registration.

Who may manage a company mailbox?

The Cégkapumegbízott administers mailbox access and appoints users known as Cégkapu-ügykezelők. An external accountant or administrative adviser may be given appropriate technical access.

Crucially, mailbox access is not the same thing as legal authority to represent a company before NAV. A separate mandate or registered authorisation may be needed for tax filings or representation.

How is Cégkapu connected to bookkeeping?

Tax decisions, clarification requests and other official correspondence may affect reporting deadlines and financial compliance. The company should establish an explicit workflow for monitoring the mailbox, forwarding relevant documents and recording actions taken.

Reliable accounting in Hungary involves more than processing invoices: it also requires timely communication between management, the accountant and the authorities.

What happens if an official message is not opened?

Not opening a notice does not necessarily prevent legal service. Under the applicable electronic delivery rules, a document may be deemed delivered on the fifth working day after the second notification if it remains uncollected. Specific procedural rules and circumstances must always be checked.

This can trigger response, appeal or missing-document deadlines and may result in avoidable administrative consequences. Check Cégkapu routinely rather than relying only on email alerts.

How long are messages stored?

Do not use Cégkapu as your only permanent archive. Documents in the inbox are generally available for a limited period, commonly 30 days, unless moved to the available long-term storage or downloaded in time. Check the relevant document’s storage and retention requirements.

Preserve official decisions, receipt confirmations, correspondence and files needed for accounting, tax or legal evidence. Statutory record-retention duties are separate from mailbox storage settings.

Five mistakes companies should avoid

Failing to check the mailbox on a regular schedule.

Assuming the accountant is responsible without assigning that duty.

Leaving former directors or employees with active access.

Confusing mailbox permissions with a registered power of attorney.

Failing to retain important notices and delivery receipts.

Frequently asked questions (FAQ)

Is Cégkapu (Company Gate) free?

Basic official registration and mailbox use are free. External advisory or administrative assistance may be charged separately.

Does every Hungarian Kft. need Cégkapu?

Generally, yes. Hungarian limited liability companies are subject to mandatory official electronic communication.

Can I use Cégkapu from outside Hungary?

Yes, if you have an accepted identification method and the appropriate access rights.

Must the director be a Hungarian citizen?

No. Citizenship alone is not decisive; practical access depends on identity verification and authorisation.

Can my accountant handle Cégkapu?

A properly authorised accountant may manage messages, but representation before authorities can require a separate mandate.

What if I do not open a NAV notice?

The document may still be deemed delivered under the applicable rules, with deadlines starting to run.

Is Cégkapu necessary for a dormant Kft.?

Yes. Having no revenue does not in itself end the company’s official communication obligations.

Is Cégkapu the same as Ügyfélkapu+?

No. The first is the company mailbox; the second is a method for identifying an individual.

How many Cégkapu accounts can a company have?

As a general rule, one per business organisation, subject to limited regulatory exceptions.
