  • Support in the implementation of the KSeF

    The National e-Invoicing System (KSeF) is an ICT system that will be implemented for mandatory use by all VAT taxpayers with a registered office or permanent place of business in Poland as of July 1, 2024. 

    The implementation of KSeF will constitute a revolution in the invoicing process, as the currently used paper or electronic invoices will be obligatorily replaced by structured invoices, i.e. invoices in XML format. All invoices will have to be sent to KSeF, where they will undergo validation and then go to the recipient. 

    Undoubtedly, this is a huge fiscal as well as technical and operational challenge, so it is not worth delaying the start of work on adapting to the upcoming changes. Otherwise, we may run the risk of a botched adjustment or a lack of readiness to meet the KSeF requirements, and this may face sanctions from the tax authorities. 

    Who is it for?
    • Does your company have its registered office or permanent places of business in Poland?
    • Is your company an active VAT taxpayer?
    • What if your accounting software provider has not provided sufficient tools to support KSeF?
    • Are you wondering how to approach KSeF implementation?
    Our support scope:
    • Support for the mapping process.
    • Pre-implementation audit.
    • Substantive verification of individual transactions / activities.
    • KSeF consultation meetings and training.

      Judgment of the Supreme Administrative Court, ref. no. I FSK 1816/20

      The court objected to the very common approach among the tax authorities, but also often among the courts, of attributing an implicit awareness of participation in a fraud by pointing out that the evidence on the record did not show that such awareness existed. The court ordered that very precise criteria be taken into account that would make such awareness of fraud plausible.

      Judgment on abuse of rights. The court questioned the authorities' instrumental attempts to apply the concept of abuse of rights, pointing out that the conditions for abuse were not met in the evidence on the record.
