Poland’s e-Delivery deadline for sole traders: how to prepare by 1 October 2026

01

Facts: who is covered by the 1 October 2026 deadline?

According to the official timetable, from 1 October 2026 the obligation to use Poland’s e-Delivery system covers non-public entities registered in CEIDG by 31 December 2024. In practice, this mainly concerns sole traders who were not already brought into scope on an earlier date.

Some businesses already need the address. New CEIDG registrations have been covered since 1 January 2025, while businesses registered by the end of 2024 that amended their entry after 30 June 2025 were brought into scope from 1 July 2025. The first action should therefore be to check the current company entry and address status.

The legal and official information in this article was checked on 14 September 2026. It is general operational information, not individual legal or tax advice.

Facts: how is e-Delivery different from ordinary email?

Gov.pl describes e-Delivery as the electronic equivalent of registered mail with acknowledgement of receipt. The service supports sending, receiving and storing correspondence, identifies the sender and recipient, and gives the communication the legal effect of registered delivery.

Correspondence sent to a public entity through the public registered electronic delivery service is free of charge. Exchanges between companies and other non-public entities may be chargeable, depending on the provider.

Usage is already substantial. On 5 August 2026, the Ministry of Digital Affairs reported more than 4.6 million active addresses in the Electronic Address Database and more than 50 million deliveries since the beginning of 2026. The mailbox is therefore becoming an everyday channel rather than a formal registration detail.

03

Facts: how does a CEIDG business create and activate its mailbox?

The official route for a CEIDG business is through Biznes.gov.pl. A sole trader can submit a dedicated application for an electronic delivery address or add the address while changing the CEIDG entry. Once the address is created, the mailbox must be activated; after activation it can receive correspondence from e-Delivery users.

Check the company details, representation and the people who will actually operate the mailbox. Confirmation that the address exists does not prove that the internal document flow is ready.

• check whether the business already has an active e-Delivery address;
• if not, use the appropriate application on Biznes.gov.pl;
• verify company data and operator permissions;
• activate the mailbox and test receipt and internal hand-off;
• record a process owner and cover for leave or absence.

WEBee recommendation: treat the mailbox as a process, not another inbox

The largest operational risk appears when access works but nobody is clearly responsible for checking the mailbox, classifying a letter and monitoring the next action. Describe a simple workflow from receipt to case closure.

A short instruction and register may be sufficient for a small business. A larger organisation may need integration with document management, a records system or task management. In every case, an automatic alert should support the accountable person rather than become the only control.

• receipt: who checks the mailbox and how often;
• classification: how sender, case, priority and owner are identified;
• registration: where receipt date, identifier and action are recorded;
• handling: who prepares and who approves the response;
• control: how deadlines, missing action and cover are monitored;
• closure: where messages, attachments and evidence are retained.

WEBee recommendation: security, records and continuity

Grant named access only to people who need it. Remove access after a role change, secure user accounts and avoid a shared password passed between employees. Retention and archiving should reflect the type of correspondence and the company’s documentation requirements.

Prepare an outage procedure as well. The public service publishes planned interruptions, and any digital service can become temporarily unavailable. Define who records the issue, where official notices are checked, how evidence is preserved and when an alternative route is considered with the person responsible for the case.

WEBee recommendation: a seven-day implementation checklist

On day one, confirm address status and authorised users. Then map the document route, name the owner and deputy, and define the case register and alerts. Before declaring the process ready, run a non-critical end-to-end test and fix every point where information can stall.

If volumes are high, several people handle correspondence or the company already uses a document system, consider integration. The Ministry provides integration information and a test environment for public and non-public organisations. Base the decision on volume, risk, available interfaces and support cost — not technical possibility alone.

• day 1: address status, company data and permissions;
• day 2: process owner, deputy and review frequency;
• day 3: receipt register, priorities and case hand-off;
• day 4: alerts, escalation and deadline control;
• day 5: archiving, access and permission removal;
• day 6: end-to-end and outage scenario tests;
• day 7: a short user instruction and process approval.
