How do I make VAT on imported Amazon orders match PrestaShop tax configuration?

When importing Amazon orders, the module can either:

• use the VAT values received from Amazon,

or

• recalculate VAT using your PrestaShop tax rules.

If you want imported orders to follow the taxes configured in your PrestaShop store, you can enable the following option.

Force tax base on tax in Prestashop

Go to:

Amazon Marketplace > Parameters > Taxes

Enable the option:

Force tax base on tax in Prestashop

Once enabled, the module will calculate VAT using the tax rules configured in your PrestaShop instead of using the VAT amounts provided by Amazon.

This is useful if:

• your PrestaShop tax rules differ from Amazon’s calculation
• you use specific local tax rules
• you want consistency between Amazon orders and regular PrestaShop orders

Important notes

• After changing this option, new imported orders will use the new tax calculation method.
• Existing imported orders are not recalculated automatically.
• Please verify that your PrestaShop tax rules, countries, carriers, and customer groups are correctly configured before enabling this option.
