Annual reporting in Bulgaria from 2027: a single system

From 1 January 2027 — a new single system for filing annual reports in Bulgaria: what companies and accountants need to know

NSI, the National Revenue Agency (NAP) and the Registry Agency are introducing the “Single Entry Point” information system

Introduction

From 1 January 2027, a new procedure for filing annual reports comes into force in Bulgaria. The National Statistical Institute (NSI), the National Revenue Agency (NAP) and the Registry Agency (RA) are launching the “Single Entry Point” information system (ISEVT), which will become the sole channel for filing certain reporting documents.

The following will have to be filed through the new system:

• Annual activity reports (AAR);
• Annual financial statements (AFS);
• Declarations under Article 38, paragraph 9, subparagraph 2 of the Bulgarian Accountancy Act.

The system provides for automatic official data exchange between the three agencies. Access to ISEVT will be provided through the NSI Single Portal.

Users are advised to prepare for the changes in advance, since registration and access rights from the current “Business Statistics” Information System (ISBS) will not be transferred automatically.

What will change from 1 January 2027?

Instead of using separate channels for filing the relevant documents, a single system will be applied. This will make it possible to organise interaction between NSI, NAP and the Registry Agency through automatic data exchange.

For companies, sole traders and accounting firms it is especially important to check access to the portal in advance, prepare electronic signatures and determine who will be responsible for filing each type of document.

What should be done right now?

1. Check your qualified electronic signature

A valid qualified electronic signature (QES) will be required to work with the portal. It may be hardware-based, mobile or cloud-based. If you already have an electronic signature, you need to check its validity period and that it works technically.

Important: to grant authority to another person, both the person granting it and the authorised person must have a QES. If a company is represented by several persons jointly, this requirement applies to all of its representatives.

2. Take into account the restrictions on using the NAP PIK

The NAP personal identification code (NAP PIK) may be used only to complete the annual activity report of individuals and sole traders (ET) who do not prepare a balance sheet.

When using the NAP PIK, you cannot:

• grant authority to other persons;
• file applications with the Commercial Register and Register of Non-Profit Legal Entities (TRRULNC) for publication of annual financial statements;
• file applications for publication of declarations under Article 38 of the Accountancy Act.

Therefore, those who need to carry out the listed actions should make sure in advance that they have a valid QES.

3. Register in the NSI Single Portal

Registration in the NSI Single Portal is mandatory for all users, including those who already work with the “Business Statistics” Information System (ISBS).

Please note: accounts and rights granted in ISBS will not be transferred automatically.

Thus, even existing users of the old system must register again and grant the relevant authority to the persons who will handle the reporting.

4. Set up authorisations and delegation of rights

In the NSI Single Portal, authority is granted separately for each obliged person — a company or an individual — and for specific actions.

Rights may be granted for:

• filing the annual activity report (AAR);
• filing an application for publication of the annual financial statement (AFS) in TRRULNC;
• filing an application for publication of the declaration under Article 38, paragraph 9, subparagraph 2 of the Accountancy Act.

Authority is granted and delegated directly in the Single Portal.

The user may permit all of the listed actions at once or grant rights only for individual operations by ticking the corresponding options in the system.

5. Distribute responsibilities between employees and accountants in advance

Companies and accounting firms are advised to determine in advance who is responsible for each stage of the reporting.

It is necessary to clarify:

• who will complete and submit the AAR;
• who will submit the applications for publication of the AFS and the declarations;
• who will sign the relevant applications;
• to whom and for which enterprises access rights must be granted.

For accounting firms serving several enterprises, this question is particularly important: the authorisations must be issued for each specific obliged person and the corresponding action.

When can you register?

The NSI Single Portal is already available for registration, granting authorisations and delegating rights. Users can therefore begin preparing in advance, without waiting for 1 January 2027.

If questions arise about working with the portal, the NSI suggests using the following materials:

• the user manual;
• the frequently asked questions section.

What is important to remember?

From 1 January 2027, the ISEVT will become the sole channel for submitting annual activity reports, annual financial statements and the corresponding declarations under the Bulgarian Accountancy Act.

To avoid delays and organisational problems, it is advisable to do the following now:

• Check that your QES is valid.
• Register on the NSI Single Portal.
• Issue the necessary authorisations anew — they are not transferred automatically from the ISBS.
• Determine who is responsible for completing, submitting and signing the documents.

Preparing in good time will allow enterprises and accountants to move calmly to the new reporting procedure and avoid unnecessary difficulties at the start of 2027.
