National e-Invoice System – important changes from July 2024

On August 7, 2023, the President of the Republic of Poland signed the Act of June 16, 2023 amending the Act on Value Added Tax and certain other acts, introducing the mandatory use of the National e-Invoice System by taxpayers from July 1, 2024. On the other hand, small and medium-sized enterprises exempt from VAT will be obliged to use the KSeF from 1 January 2025.


What is the National e-Invoice System?

The National e-Invoice System is a nationwide ICT system that allows issuing e-invoices. The purpose of KSeF is to provide taxpayers with a tool for issuing and submitting structured invoices, which, apart from paper invoices and electronic invoices, are one of the acceptable forms of documenting transactions.

The National e-Invoice System has been available since January 1, 2022. The Ministry of Finance emphasizes that the systematized e-invoice standard is intended to simplify and automate the documentation of transactions, which is intended to reduce costs for taxpayers and speed up the entire invoicing process.


The National e-Invoice System – the most important assumptions

The main assumptions of the act introducing the mandatory KSeF include, above all:

  • mandatory use of KSeF by taxpayers from July 1, 2024,
  • for small and medium-sized enterprises exempt from VAT, this deadline is January 1, 2025,
  • consumer invoices and tickets that function as invoices (including motorway receipts) as well as invoices issued in OSS and IOSS procedures will be excluded from KSeF,
  • the sanctions were mitigated compared to the original assumptions, while their application was postponed until January 1, 2025, which gives taxpayers time to familiarize themselves with the system and adjust the company without suffering consequences due to errors,
  • in the event of technical problems on the part of the taxpayer, it is possible to issue invoices offline outside the system and submit the invoice to the KSeF on the next working day after issuing it offline,
  • only until 2024 invoices from cash registers can be issued in the current form,
  • also until the end of 2024, a fiscal receipt with a tax identification number will be considered a simplified invoice.

What are the benefits of using the National e-Invoice System?

The Act provides for a number of benefits for taxpayers, including tax benefits and benefits related to the general functioning of their companies. The main benefit for users of the KSeF is the possibility of refunding the tax on goods and services in a shortened period of 40 days, instead of the standard 60 days, which may have a positive impact on financial liquidity.

The Ministry of Finance emphasizes that the introduction of KSeF eliminates the need to issue duplicate invoices – documents will be stored in the system for 10 years, so contractors will have access to the invoice at any time.

Tax authorities will have permanent access to KSeF, therefore it will no longer be necessary to send invoices on demand (JPK_FA). Taxpayers will have access to issued invoices on an ongoing basis, which has a large impact on company management.
