The next time you will need to pay VAT is be in their hands before the 7th day following the vat quarter end.

May I suggest that you apply for direct debit as it gives a further 5 days, its is automatcially taken out and you will never receive any late payment penalties.

To pay your vat bill you can pay with debit or credit cards here

You will also need your VAT number.  If you do not have it please request it from me here
