VAT Calculation Service Updates

March 25th, 2026 by FabioR_Amazon

Starting April 1, 2026, Amazon is adding a new column to the VAT Calculation Report for Polish e-invoice compliance, and starting June 1, 2026, the VAT Calculation Service will shift to shipment-level tax calculations across ten EU marketplaces. Refer the the following announcements for more information.

Polish KSeF E-Invoice Column Addition to VAT Calculation Report

Starting April 1, 2026, Amazon is adding a new column to the VAT Calculation Report (VCR) to support Polish e-invoicing compliance requirements. The new KSeF Number field will display the invoice number provided by Poland's National e-Invoice System (KSeF) for successfully submitted electronic invoices. This change ensures that sellers using Amazon's VAT Calculation Service have complete visibility into Polish e-invoice submissions and can maintain compliance with Poland's mandatory e-invoicing regulations under the KSeF system.

Which marketplaces are affected?

This change applies to the Poland marketplace.

Who is affected?

Sellers who are enrolled on VCS and who use the VAT Calculation Report to fetch the list of orders for which Amazon has created invoices or e-invoices on their behalf.

What action is required?

Update your code to include the new column information in your SC_VAT_TAX_REPORT report.

VCS Tax Calculation Method Changes for EU E-Invoicing Compliance

Starting June 1, 2026, the VAT Calculation Service will calculate tax at the shipment level by applicable tax rate instead of by individual unit. VCS users who issue their own invoices through integrators must ensure that their systems are compatible with this change. If you don't update your system, it may not be able to generate invoices for your seller clients, or it may create incorrect invoices.

Which marketplaces are affected?

This change affects the following marketplaces:

  • United Kingdom (UK)
  • Germany (DE)
  • France (FR)
  • Italy (IT)
  • Spain (ES)
  • Netherlands (NL)
  • Poland (PL)
  • Sweden (SE)
  • Belgium (BE)
  • Ireland (IE)

Who is affected?

Developers with applications that provide invoicing services to Amazon sellers enrolled in the VCS program are affected by this change.

What action is required?

If you have an application that is affected by this change, be sure to:

  • Update your invoicing system to handle shipment-level VAT calculations by the applicable rate. Tax amounts will be calculated on the total invoice net amount by the applicable tax rate rather than by single unit or quantity. Depending on the customer, VCS may calculate VAT from the VAT-inclusive price (impute VAT from total invoice gross amount) or exclusive of price (compute VAT from the total invoice net amount).
  • Ensure compatibility before June 1, 2026. The VAT Invoice Data Report (VIDR) schema won't change, but your system must handle shipment-level VAT calculations by the applicable rate.
