I received my EIN tax number as I reside in one state. Do I need an EIN number for ALL states?

Am I required to register for an EIN number in all US states?

Hi @AnnB,

Ted here from Shopify, thanks for posting your query! 

In short, you are only required to have one EIN number but more info can be found here if you would like to take a look. Are you looking to set up Shopify Payments? How are you finding the platform so far? 

Many thanks,
