Start selling in Amazon USA

We want to start selling in Amazon USA. We currently have a UK Ltd, VAT registered and we are selling in Amazon UK.

Does anyone know, from experience only, what tax obligations we will have ? Also is there anyone who could do this process for us (probably VA or accountant ) ?

Sale produce in us through Amazon or your own website, the tax liabilities are: sales tax and income tax.

In most states, based on platform facilitated rule, amazon is labile for sales tax collection. However, if you sale via your own website, then you need file sales tax and corporate income tax.
