Current and Historical Rates
The Current Standard Rate is 20%
The current system was introduced just after the UK's entry into the European Economic Community (EEC) on 1st January 1973. It replaced the previous Purchase and Selective Employment Tax. The Chancellor announces any changes during The Budget or Autumn Statements.

Exceptions from the Standard Rate
Most exceptions incur a lower rate of tax as follows:
- Zero-rated items such as children's clothes and some food.
- Exempt such as bank interest paid and received.
- Reduced rate of 5% for some energy saving products such as solar panels installed in your home.
- Electricity or gas for domestic premises is 5% where businesses pay 20%.
Businesses not registered for VAT should not charge it for sales invoices. You have to register if your turnover for the previous 12 months or 30 day period is over a certain threshold. The current threshold is £85,000 for the tax year starting April 1th, 2017 (source: HMRC).
Most businesses complete a VAT return each quarter. If output tax exceeds input tax, then the difference is paid to HM Revenue and Customs (HMRC). If the reverse is true, then HMRC provide a refund. You can either pay through or account or online at the Tax Service website.

How to Calculate Results at the Current Rate of 20%
If you have a gross amount and want to determine the net value, then simply divide the gross value by 1.20 to provide the net value. For example, an invoice that includes VAT totalling £150 would have a VAT amount of £25 with the net value at £125. This result is calculated by dividing £150 by 1.2 which gives the net value of £125 with the difference being the tax at 20%.
If you have a figure you want to add VAT against, multiply by 0.20% to find the VAT value or 1.20 to find the gross value including VAT. For example, an invoice of £125 multiplied by 20% provides a VAT figure of £25.
The net amount is the value you use in your accounts for purchases and sales if you're a VAT registered company.
