Taxes - UK base - US Fulfilment centre - US customers

[TheJeepDon]

Hi All,

I'm wondering if anyone can help.

We're a UK registered company with our physical office in England.

Our products are shipped straight to our fulfilment center based in Arizona, USA.

They are then sold to customers based in the USA only.

What taxes should I be collecting, and how should I set that up on my product listings/basket/checkout in the Shopify store?

Thanks
