Poland’s Ministry of Finance clarified that non‑resident businesses are subject to KSeF e‑invoicing only if they have a Polish fixed establishment (SMPD/FE) that participates in the specific supply. The rule, effective 1 February 2026, does not trigger on a Polish VAT registration alone and requires a full assessment of the fixed establishment’s involvement per transaction.
From 1 February 2026, KSeF e‑invoicing is mandatory for non‑resident businesses that have a Polish fixed establishment involved in the transaction.
No, a Polish VAT number alone does not trigger KSeF; only a fixed establishment that participates in the supply does.
The fixed establishment must have personnel and technical resources, sufficient permanence (not just a postal address or passive warehouse), and be involved in the transaction.

On 11 February 2026, the EU General Court ruled that Polish VAT deduction rules are inconsistent with EU law, allowing businesses to deduct VAT in the month the transaction occurred if the invoice is received before the filing deadline. The decision invalidates the practice of postponing deductions to the next settlement period and is binding on Polish tax authorities, potentially improving liquidity for taxpayers. The ruling may prompt amendments to national regulations.

The rule applies regardless of whether the original purchase allowed a 100% or 50% VAT deduction, as confirmed by a 2025 tax authority interpretation.
