You're considered the importer of record if your business is responsible for making sure that your products are imported according to local customs. Use the importer of record setting to control who should collect customs duties and import taxes for a transaction.
You're automatically set as the importer of record for any country that you add in AvaTax, but this setting can be changed at any time.
How the Importer of Record impacts transactions with customs duties
When it's checked, you’re responsible for any customs and import taxes. They'll appear in your transactions or in tax calculations at checkout.
When it isn't checked, the buyer is expected to pay customs and import taxes on delivery. Those amounts aren't included in transactions because you're not responsible for them.
What's the right setting for my shipping agreement?
Check Importer of Record if the buyer is the importer of record in your shipping agreement but you still want to collect duties and taxes in transactions, such as when using a Delivered Duty Paid shipping service.
Uncheck Importer of Record if you're using a Delivered at Place shipping agreement where the buyer is expected to pay customs and import taxes on delivery.
