From the 1st of July, 2021 new EU VAT legislation requires online marketplaces to collect and declare the VAT paid on goods entering the EU valued at less than 150 EUR. In order to inform couriers that this tax has been collected by the marketplace, marketplaces will be required to attach an IOSS number to every order that meets these criteria.
Marketplaces not on the list above do not make their IOSS numbers available to Linnworks when capturing orders. If you know the IOSS number for the marketplace you're selling on, you can configure the Rules Engine to assign the IOSS number for you.
First, add a new rule (Orders > Rules Engine) and add a condition to that rule that checks the integration the order was placed on, the destination country, and the order's subtotal.
You can use the 'matches one of' condition to check all EU member states at once, so you only have to add one condition.
Next, add an action that adds the IOSS number to the order. To keep things consistent with other channels, we'll use an extended property called MARKETPLACE_IOSS.
