Electronic Invoicing, KSeF and SAF-T e-Reporting in Poland

KSeF and SAF-T: How Tax Compliance Is Changing in Poland

The KSeF mandate changes how companies issue and receive B2B invoices in Poland. Instead of exchanging documents directly, companies must generate structured invoices and submit them to the national system for validation and assignment of a unique identifier. This model requires companies to review their ERP connections, response handling, and procedures for situations in which the platform is unavailable.

KSeF operates alongside SAF-T-based e-Reporting obligations. While KSeF is involved in the invoice exchange itself, JPK files transmit tax and accounting information to the tax authorities. JPK VAT covers VAT records and returns, while JPK_CIT extends electronic reporting to corporate income tax. The electronic invoicing and e-Reporting framework in Poland provides an overview of both obligations within the country's implementation timeline and technical requirements.

The challenge is not simply generating XML files. Companies must extract data from their internal systems, adapt it to the required structures, and maintain consistency across invoicing, accounting, and tax reporting. When multiple legal entities or ERPs are involved, differences in master data or validation rules can lead to rejections and manual work.

This video provides an initial overview of how KSeF and SAF-T work. It is particularly useful for finance, tax, and IT teams that need to identify which internal processes will be affected before beginning the technical implementation.
