New Poland eInvoice regulations are due to come into effect from 1st February 2026. Businesses with a fixed establishment in the country will need to ensure their compliance.
Following a voluntary phase which started in 2022 for B2B transactions, the Polish authorities plan to introduce mandatory B2B invoice reporting via their online system, Krajowy System e-Faktur (KSeF).

In this blog, we outline the requirements applicable to those operating in Poland and how we can help businesses meet this new eInvoice mandate.
Summary of Poland eInvoice deadlines
Poland has been phasing in eInvoice regulations for several years, similar to many other European countries.
Below is a summary of the existing and upcoming eInvoice and tax reporting deadlines for businesses with a fixed establishment in Poland:
B2G transactions mandated since April 2019
A voluntary phase for B2B transactions introduced in January 2022
B2B entities with a turnover exceeding 200 million PLN (approx £40 million/$50 million) mandated from 1st February 2026 for
The requirement expands to all others from 1st April 2026.
Submission and reporting requirements
New eInvoice mandates often mean new operational complexities.
Polish eInvoicing regulations follow a Continuous Transaction Controls (CTCs) framework, which mandates the real-time reporting of financial data to the tax authority. This information must be reported using an approved method in the permitted format via the Polish online system called Krajowy System e-Faktur (KSeF).
The new system requires all invoices to be submitted using ‘Faktura’ format and attachments are not permitted. The KSeF system validates the invoices submitted and assigns a unique ID number, making it a legally valid invoice. Businesses ultimately have two choices when it comes to submission – an API connection or manual upload. Businesses also must ensure they hold an electronic archive of invoice records for 10 years.
For any business required to meet this new mandate, it can be overwhelming when considering how these new invoice processing requirements can be fulfilled.
For example, those considering a ‘no-cost’ route and managing the compliance requirements in-house via a manual reporting process, will experience challenges with high volumes of invoice data and any corrections. This could also become a costly route as there will be sanctions for non-compliance. These sanctions can include fines of up to 100% of the VAT due, or 18.7% of the total value of the invoice.

Businesses affected by the new Polish requirements should favour a reliable solution that removes this compliance headache.

We also recommend the strategic use of document transformation solutions to offset the cost of compliance. Typically, an extortionate amount of time is spent on manual document processing within the Accounts Payable team. For example, rekeying invoice data from PDF files into the finance management system. This inefficiency can be eliminated through the use of an AP Automation solution that captures inbound documents, extracts the relevant data, and adds it to the relevant system for approval.
