A foreign customer who does not provide a valid tax number can place an order as a private individual and will be charged VAT.
Exclude selected customers
- You can indicate countries for which tax number validation will not take place - always charge VAT 0%.
- You can indicate customer accounts for which VAT 0% will always be charged, regardless of the result. validation of their tax number.
- You can indicate customer accounts for which the correct tax will always be charged.
Messages
If a foreign customer passes validation, the module will display a message in My Account about the 0% VAT rate that will apply to purchases in your store.
In the module configuration, you can choose which messages you want to display for the customer:
- 0% VAT rate message in My Account / in the shopping cart / when placing an order.
- Information at the top of the page throughout the store.
- Information only when editing the billing address.
Validation process of saved tax numbers in customer addresses:
The module validates all tax numbers saved in the addresses on the customer's account, including addresses added before the installation of the module.
Validation of the tax numbers saved in the customer's account is done in the background, when the customer logs in to your store.
If any of the tax numbers on the customer's account turns out to be inactive, the module will display a message to the customer with the information.
ERP programs
Programs, such as ERP will retrieve from your store the correctly formatted and active tax number and the corresponding VAT rate.
Satisfied customers and accountants
You will not lose foreign customers who expect orders with 0% VAT.

Changelog (v1.12)
## v1.12.9 - 2026-09-04
### Fixed
* Valid EU VAT numbers are no longer occasionally reported as invalid during brief VIES overloads; the number check now retries before giving up.
## v1.12.8 - 2026-08-28
### Added
* A tax rule can now be selected to describe order lines covered by the 0% VAT
exemption. Previously such a line was saved with a zero rate but no tax name and
no tax breakdown row, so invoicing modules and PDF documents could not tell an
exempt line from an untaxed one and fell back to a bare 0%. With the new option
set, the line carries that tax rule's name and a zero-value breakdown row, which
is what an intra-Community designation such as KBAET requires. The rate stays at
0% and order totals are unchanged. The option is empty by default, so existing
shops keep their current behaviour.
## v1.12.7 - 2026-08-13
### Added
* Monaco (MC) can now be selected for VAT number validation and qualifies for the
0% VAT decision. Monaco lies inside the French VAT territory (Directive
2006/112/EC art. 7), so its companies hold FR VAT numbers; the VIES query is
driven by the number prefix, so those numbers are checked as French ones with
no extra mapping. Previously a Monaco address was rejected before validation ran
and MC could not even be ticked in the module's country list.
## v1.12.6 - 2026-06-11
### Fixed
* The "0% VAT applied" info banner no longer appears for customers who merely
have a VAT number in their address while being charged the standard rate.
The banner now follows only the actual tax decision for the customer.
* The banner now also appears for customers with the per-customer 0% VAT
override when their cart is empty or not yet created.
## v1.12.5 - 2026-06-01
### Fixed
* The "0% VAT applied" info banner could appear for customers actually charged
standard VAT. The banner flag now resolves the tax address via
`PS_TAX_ADDRESS_TYPE` (the same way PrestaShop does for the tax calculation),
so it always matches the tax actually charged. Previously it always read the
invoice address, disagreeing with the tax decision on shops that compute VAT
from the delivery address.
## v1.12.4 - 2026-05-12
### Fixed
* 0% VAT info banner now also appears for customers receiving 0% via the
per-customer `always_remove_tax` override, and renders immediately on page
load instead of waiting for the AJAX VIES round-trip.
## v1.12.3 - 2026-05-11
### Added
* Configuration switch "If VIES is unavailable, treat the tax number as valid
(only on the customer's first order)". When enabled and VIES is confirmed
down via `checkStatusService`, first-order EU B2B customers are accepted (and
0% VAT applies) instead of being blocked by the upstream outage.
## v1.12.2 - 2026-04-30
### Fixed
* B2B (0% VAT) customers in a customer group with a percentage reduction were
charged a small residual tax on top of the discounted product price. The
gross→net correction for fixed-amount specific-price discounts is now scaled
by the customer-group reduction so it lines up with the rest of the price.
## v1.12.1 - 2026-04-30
### Fixed
* `hookTaxManager` no longer bails out when no customer is loaded in the context.
The customer id is now derived from the address (`Address->id_customer`) as a
fallback, so per-customer VAT overrides and address-based 0% VAT logic work
in BO order edits and other contexts where `Context::getContext()->customer`
is not set (e.g. direct `TaxManagerFactory::getManager()` calls).
## v1.12.0 - 2026-04-24
### Added
* New configurable info banner when VAT 0% is applied — choose between: disabled, shown on account/cart/checkout pages, or shown everywhere.
### Fixed
* Background VAT validator incorrectly showing error banner for customers from countries excluded from validation.
## v1.11.9 - 2026-03-31
### Fixed
* Fixed 0% VAT incorrectly applied when delivery address has VAT but invoice address belongs
to a private person. The invoice address now determines VAT exemption status.
* Added missing migration
## v1.11.8 - 2026-03-31
### Fixed
* Fixed B2B pricing for fixed-amount gross discounts — the full gross discount was subtracted
from the net price instead of being converted to net first, resulting in incorrect final prices.
## v1.11.7 - 2026-03-16
### Fixed
* Fixed 0% VAT not applied when invoice address has valid EU VAT number but delivery address
belongs to a private person (no VAT). The module now checks the invoice address for VAT
qualification when the delivery address does not qualify, as long as both addresses are
in the same country.

Mam pytanie: czy planujecie autouzupe艂nianie danych o firmie na podstawie podanego numeru NIP z GUS? :-)
Gdyby co艣 si臋 dzia艂o skorzystajcie z helpdesk.prestashow.pl
- robi臋 zakup i podaj臋 NIP UE, odlicza si臋 VAT (stawka 0% si臋 ustawia)
- przez finalizacj膮 zakupu cofam si臋 do formularza adresu i dodaj臋 nowy adres, tym razem bez NIPu (a co tam, jednak chc臋 kupi膰 prywatnie)
- pomimo 偶e pole NIP jest puste i oznaczone jako opcjonalne, wyskakuje b艂膮d 偶e NIP nieprawid艂owy
. - Nie mieli艣my okazji testowa膰, ale je艣li Tw贸j modu艂 u偶ywa standardowych mechanizm贸w PrestaShop do przetwarzania adres贸w, dzia艂anie modu艂u powinno by膰 prawid艂owe. Je艣li b臋dzie inaczej - wycenimy dostosowanie dzia艂anie modu艂u do Twojego koszyka.
