Hi @thefutrplam,

Thank you for getting in touch. Taxes in the US can be complex and knowing when to charge taxes to customers can vary depending on a number of factors, such as the type of products being sold and where they are being sold to. Generally, merchants only need to charge and remit taxes in states where they have a tax nexus, which can be based on physical factors (such as having employees or a warehouse in a state) or economic ones (such as making a certain number of sales to a state in a calendar year). 

I would recommend checking out our guide on US taxes to learn more, but would also suggest speaking to a tax professional if you are unsure of your obligations.
