I'm going to be setting up a ltd business with a business bank account, just not sure whether I need to be VAT registered?
What country are you in?
You don’t need to be VAT-registered if your turnover is below the registration threshold, but it can be beneficial to register voluntarily. Your receipts from Apple are an international business-to-business transaction, so are “reverse charged” i.e. in effect no VAT, but your expenses will likely be domestic (e.g. buying computers), so you reclaim VAT on them.
