KSeF: A timeline of Poland’s e-invoicing mandate

December 15, 2022

Electronic invoicing in Poland via KSeF has undergone a long journey. Providing new expectations for B2B and B2G transactions alike, it is vital for taxpayers to understand what’s to come – though that can be tough when rules and regulations change frequently.

This blog provides a comprehensive timeline of Poland’s advancement towards its e-invoicing mandate, detailing the adjustments your organisation should be aware of. The cost of non-compliance reaches beyond financial penalties, so knowledge is vital.

New E-invoicing Mandate Dates Announced

The Polish Ministry of Finance announced the new official implementation date for mandatory e-invoicing via KSeF during a press conference. The new timeline is as follows:

  • 1 February 2026 – for taxpayers whose turnover exceeds PLN 200 million (approx. EUR 46 million) in the preceding year
  • 1 April 2026 – for all other taxpayers

The Ministry of Finance emphasised that an earlier implementation date for the mandatory KSeF would not be feasible due to findings from an external technical audit. Consequently, the KSeF system will require a comprehensive architectural rebuild.

Further information concerning technical specifications and necessary legal amendments will be published in the coming months.

Poland Postpones E-invoicing Mandate Rollout

Poland’s Ministry of Finance announced today the postponement of its e-invoicing mandate. Originally scheduled for July 2024, the initiative has been postponed indefinitely due to major errors identified in the KSeF system.

The Minister of Finance emphasised that the current technical status of the KSeF system poses substantial challenges, preventing its secure implementation in Poland. Critical errors were identified in the code, affecting overall system functionality and performance of KSeF, prompting the Ministry to take decisive action.

To address these issues, the Ministry of Finance will initiate an external audit to assess the functioning of the KSeF system and evaluate the preparedness for its implementation. The final date for the introduction of mandatory e-invoicing will be contingent upon the results of these audits. In addition, the Ministry will intensify consultations with businesses regarding KSeF.

While expressing full support for the implementation of the KSeF system, the Ministry of Finance reiterated that their priority is to ensure the proper functionality of the system. This commitment stems from the need to secure the economic turnover in the country and avoid situations where taxpayers might be unable to issue e-invoices due to KSeF errors.

However, it still includes the obligation to include the unique ID number (numer KSeF) in the VAT return, in case the number has been assigned on the invoice, from:

Poland Confirms Changes to E-invoicing Mandate

Poland has published the second draft law amending the VAT Act and certain other laws on the Government Legislation Centre on 15 March 2023.

The amendments mainly confirm previously announced changes, though some additions are worth noting. The essential clarifications include:

1. Scope of the KSeF mandate

  • Postponement of the KSeF mandate from 1 January 2024 to 1 July 2024, with some exceptions
  • VAT-exempt taxpayers will be in scope from 1 January 2025
    • From 1 January 2025,it will not be possible to issue invoices using cash registers and simplified invoices in the current form
  • The mandatory scope of the KSeF system will exclude invoices for B2C transactions, and invoices issued and settled for OSS and IOSS will not be included in the mandate.
  • Foreign taxpayers with a fixed establishment in Poland performing activities required to be invoiced according to Polish VAT law will be obliged to issue invoices via KSeF, to the extent that this permanent place of business relates to the supply of goods or services which are invoiced

2. Corrective notes excluded from KSeF

The draft law entirely withdraws the possibility for buyers to issue corrective notes. Buyers cannot propose corrections to the original invoices through or outside KSeF, which the previous draft law presented. Accordingly, changes in the issued invoice can be made only by issuing a corrective invoice.

3. Issuing invoices outside KSeF in case of failure

In line with the previous draft proposal, the current draft law specifies the possibility of issuing e-invoices in offline mode – outside of KSeF in a structured format and delivering to KSeF on the next business day – in case of a failure on the taxpayer side.

The Ministry of Finance will communicate relevant information to the public regarding any maintenance work conducted in KSeF or any system failure. During this time, taxpayers can issue invoices outside of KSeF and deliver them to the buyers in the agreed format.

Such invoices must follow the structured format, be assigned with a QR code and, after the failure ends, be delivered to KSeF within seven days. The date of issuance will be the date stated in the P_1 field, while the buyer’s receipt date will be the date when KSeF assigned the unique ID.

4. QR code

The government has added a new requirement for including a QR code on the invoices issued during a failure of the KSeF system. As previously announced, the QR code must also be included on the invoice visualizations issued outside of KSeF, for example, to foreign buyers and on the VAT RR invoices and corrections to them.

5. Self-billing process under KSeF

The Ministry of Finance responded to feedback about the lack of a self-billing process for cross-border transactions. Therefore, a method of authentication in KSeF for foreign buyers will be included in KSeF, allowing foreign buyers to issue structured invoices on behalf of the suppliers.

6. Exchange rate

The exchange rate used for converting foreign currencies into PLN currency can be maintained from the day preceding the date indicated in the P_1 (date of invoice issuance).

The exchange rate will be calculated based on the date when an e-invoice was issued (stated in the P_1 field), provided that an e-invoice is sent to KSeF no later than the day after the date indicated in the P_1 field.

7. Penalties

Sanctions will apply from 1 January 2025 (previously 1 July 2024) up to 100% of the amount of VAT indicated on the invoice or up to 18.7% of the total amount due shown on the invoice. However, no minimum penalty amount will apply – previously, it was 1000 PLN – approx. 200 EUR.

 

Next steps for Poland’s KSEF e-invoicing mandate

The draft law is expected to be published in Q3 of 2023, with most provisions applying from 1 July 2024.

Accordingly, the associated final schema FA (2) and FA (RR) are also planned to be published at the end of June or the beginning of July, as announced by the Ministry of Finance during a conference on 16 February 2023. Therefore, we are still waiting for the legislative process to be completed for the e-invoicing mandate to take effect.

Poland: E-invoicing Mandate Postponement to 1 July 2024

According to an official announcement published by the Ministry of Finance on 2 February 2023, the go-live date of Poland’s mandatory e-invoicing system is now 1 July 2024 – delayed six months from the previous date.

More than a year after the roll-out of the voluntary phase and following extensive testing of the KSeF system by taxpayers, the Ministry of Finance responded to the feedback submitted in the public consultation by delaying the mandate and relaxing certain requirements.

The expected changes are:

  • The e-invoicing mandate will be postponed from 1 January 2024 to 1 July 2024
  • VAT-exempted taxpayers must comply with the e-invoicing requirements and issue invoices via KSeF from 1 January 2025
  • The KSeF system will exclude B2C transactions
  • Invoices issued through cash registers and simplified invoices can be issued in their current form until 31 December 2024, meaning such invoices will be in the scope of KSeF from 1 January 2025
  • In the case of a technical failure on behalf of the taxpayer, they will be able to issue invoices outside of KSeF and transmit them to the system the next day
  • Penalties will be postponed until 1 January 2025 and imposed on taxpayers on a case-by-case basis

Taxpayers should not treat the postponement of the e-invoicing mandate as a reason to pause the implementation process. Instead, treat the delay as an incentive to implement complex legislative and technical requirements before the go-live date and adapt their accounting and invoicing processes considering any errors that may appear.
