Tax identifiers allow you to meet international shipping and customs requirements when creating shipments and can be easily managed within SKULabs.
There are three places to set federal and state tax ids:
Editing your store's origin address tax identifier field
Using the Tax Identifiers feature covered below
Using shipping rules to "Set tax identifier" or "Set tax ID" on orders
First, go to the Tax Identifiers page to manage, add, update and remove tax identifiers. A tax identifier contains the following attributes:
Name - an optional description of the tax identifier
Entity - the party the tax identifier is issued to. e.g. Sender or Receiver
Tax ID - tax identification number
Type - the type of the tax identification number, e.g. IOSS, EORI, VAT, etc.
Issuing country - the country that issued the tax identification number
Next, create a shipping rule with filter criteria as desired, "Set tax identifier" as the action, and the tax identifier as your action parameter.
You will then notice the tax identifiers in the package information section when creating a shipment.
Please contact SKULabs support if you have any questions.
