VAT is a complex area and requires accurate record keeping and prompt settlement of any liability on a quarterly basis.  Once registered, you are legally responsible for making a correct VAT return and for payment of VAT on time.  

It can be advantageous for you to register voluntarily when your business costs or purchases include VAT and most of your customers are VAT registered so they can claim back the VAT you will need to add to your sales.

There are various schemes for smaller businesses, designed to minimise the administrative burden and to help improve cashflow and budgeting.  The service is designed to help ensure you are aware of the key filing deadlines and penalties for late filing.
