Businesses that are registered for VAT (value added tax) need to pay HMRC a certain percentage of the money they receive from any ‘taxable supplies’, which includes things like business sales, commission, and the sale of business assets.
Even if you haven’t charged VAT to the customer, you will still have to pay the VAT amount to HMRC. That’s why it’s essential that you know what you need to charge VAT on, and that you know how much VAT you need to charge.
Value-added tax (VAT) must be paid on all taxable supplies. If you’re unsure of the rate for your supplies, check HMRC’s guidelines.
