Addition of Polish E-Invoice Columns to VAT Invoice Data Report
Starting March 27 2026 Amazon.pl will add two new columns, buyer-nip and seller-nip, to the VAT Invoice Data Report (VIDR). These fields contain the Polish NIP of both buyer and seller (e.g., 123‑456‑78‑90) and are required for compliance with Poland's e‑invoicing law.
Back to All Starting March 27, 2026, Amazon is adding two new columns to the VAT Invoice Data Report (VIDR) to support upcoming e-invoicing mandates in Poland. These columns will accommodate the Polish National Identification Number (NIP) for both buyers and sellers, as Poland's e-invoicing regulations require NIP information in addition to standard VAT Registration Numbers (VRNs).

Analysis & Recommendations
Why This Matters
Polish sellers using the VAT Calculation Service must capture both buyer and seller NIP to generate compliant e‑invoices. Without the new columns, VIDR imports will fail after March 27 2026, disrupting tax reporting and potentially incurring penalties.
Key Takeaways
- Two new columns – buyer-nip and seller-nip – are added to the VIDR for the Poland marketplace.
- The change goes live on March 27 2026; reports lacking these columns will cause import errors.
- NIP must follow a nine‑digit pattern with optional hyphens (e.g., 123‑456‑78‑90).
- Only sellers enrolled in the VAT Calculation Service (VCS) on Amazon.pl are impacted.
Recommended Actions
- →Update your CSV/TSV parser to expect 12 columns (add buyer-nip and seller-nip) via Seller Central > Reports > VAT Invoice Data Report settings.
- →Add buyer_nip and seller_nip fields to your invoice database schema and implement validation for the 9‑digit NIP format.
- →Download a test VIDR from the VCS portal or API before March 27 2026 and set up alerts for missing buyer‑nip or seller‑nip columns.
