Quick question. My business is setup in the UK as an LTD. My supplier is based in the US and we plan to sell to US customers only. Would my customers be responsible for US sales tax or would I given I would already be paying UK taxes? Surely as long as my customers are paying into my UK bank account, IRS wouldn't treat it as taxable income? As long as I register for a US sales tax ID/resellers license I should be fine right? I don't want any Double Taxation Agreement.
