Everything You Need To Know About Invoicing In the UK

Some UK businesses must charge one of three Value-Added Tax (VAT) rates on their invoices. Find out if you have the same obligation and learn more about VAT in general below.

VAT & VAT Registration:

When starting a new business in the UK, you will not be registered for VAT. You will need to get a VAT Number and add it to every invoice. If you register for VAT, you will start generating and sending tax invoices containing VAT details.

Registration is mandatory for businesses with a VAT taxable turnover of more than £85,000, but you can also register voluntarily if your turnover is less than that.

VAT Returns:

As a VAT registered business, you will have to submit a VAT return to HM Revenue and Customs (HMRC) every 3 months, known as your ‘accounting period’. A final VAT Return is submitted by businesses that are having their VAT registration cancelled.
