- Invoices received from foreign suppliers (both EU and non-EU) do not need to be reported to the KSeF system.
- KSeF is intended for issuing and sending invoices according to Polish VAT law, mainly for domestic sales and certain sales to foreign clients if Polish law requires invoicing.
- Foreign invoices serve as documentation of business expenses and are not subject to KSeF reporting, though they may affect tax obligations.
- Only invoices issued in Poland, including those for sales to foreign clients when required by Polish law, must be reported in KSeF.
- KSeF does not replace accounting for purchases or require reporting of cost invoices from foreign suppliers.
