What about countries with a de minimis?

[Arienne]

the UK has a VAT de minimis of 135 GBP, and I do DDP shipping. Is there any way I can apply a tax only to cart totals over the de minimis? This is a pretty critical feature for tax compliance.

Yes, but not with PrestaShop core settings.

In PrestaShop, tax is calculated per product (tax rules) based on the customer’s address, not based on the cart total, so there’s no native “apply VAT only if cart > £135” switch. PrestaShop Help Center

Also, just to align on the rule: UK guidance states that for consignments ≤ £135 VAT is collected at the point of sale, while for > £135 VAT is paid at import (the exact handling can vary with DDP and your setup). GOV.UK+1

Practical options

1. Custom module (best for compliance)
Implement a rule in checkout/tax calculation: if cart (consignment) total > 135, apply a specific VAT logic; otherwise apply the other one. This keeps VAT shown correctly as tax (not as a “discount/fee”).

2. Workaround (not ideal): fee product / cart rule
Create a cart rule triggered at > £135 that adds a “VAT/Import charges” product or fee. This can work mechanically, but accounting/tax display can be messy.

If you tell me your exact goal (charge VAT only above £135, or only below £135) and whether prices are tax-included, I can give you the cleanest implementation approach for PrestaShop + DDP.
