Will e-Delivery have an impact on KSeF?
In recent years, a number of changes have been introduced in Poland aimed at digitization of processes administrative and fiscal. Two key systems that are causing a big stir among entrepreneurs are. e-Delivery and KSeF (National e-Invoice System)However, do the two tools have any relation to each other? Will the introduction of e-Delivery affect the operation of KSeF? We answer these questions in the following article.
What are e-Delivery and KSeF?
Before we move on to analyze the mutual impact of these systems, it is worth recalling what they are and their functions.
- e-Delivery it's a system electronic correspondence with offices and courts to replace traditional registered letters. This will allow citizens, businesses and institutions to receive and send official letters digitally with acknowledgement of receipt.
- Implementation status for 2025: The e-Guarantee system is already mandatory for public administration and companies registered in KRS. Entrepreneurs with sole proprietorships will be required to use e-Guarantees starting in 2025, but implementation will be gradual.
- KSeF (National e-Invoice System). is a platform for issuing, receiving and storing electronic invoices in a structured format. Its goal is to automate and tighten the tax system and reduce the time for business-to-business settlements.
Will e-Delivery affect KSeF?
No direct functional link
The two systems are independent of each other and have different purposes. KSeF pertains to invoicing and tax settlements, while e-Delivery is used to communicate with authorities. Businesses using KSeF do not automatically have to use e-Delivery for the same purpose.
Common direction: digitization of administrative processes
Although e-Delivery and KSeF are not closely related, the two systems are part of a broad plan to digitization of administration and economic processes in Poland. Their introduction is expected to reduce bureaucracy and simplify contacts between entrepreneurs and authorities.
Possible integration in the future
It is not ruled out that in the future e-Delivery could be used to notify companies of important information related to KSeF, such as invoice errors, new regulations or tax audits. At this point, however, there is no official information on such integration.
Obligation for entrepreneurs
Both e-Delivery and KSeF will be mandatory for businesses in the future:
- KSeF starting in 2025 (exact implementation date still unknown after postponement).
- e-Delivery from 2025 are mandatory for newly registered sole proprietorships, and are already required for companies registered with the KRS and public administration. This means that in practice many companies will have to use both systems simultaneously, albeit for different purposes.
At this point e-Delivery has no direct impact on KSeF, as they perform different functions. However, both systems are elements of the digitization of Polish administration and may complement each other in the future. Entrepreneurs should keep track of changes in regulations and adapt to new requirements to avoid problems with the implementation of both systems.
