Corporation Tax rates and reliefs

Skip to contents of guide


The Corporation Tax rate for company profits is 19%

You pay Corporation Tax at the rates that applied in your company’s accounting period for Corporation Tax.

There are different rates for ‘ring fence’ profits of companies involved in oil rights or extraction in the UK or UK continental shelf.

You may be able to get deductions or claim tax credits on your Corporation Tax. These are known as reliefs.

Previous rates

The rate you pay on profits from before 1 April 2015 depends on the size of your profits.

Work out your profits when you prepare your Company Tax Return.

If more than one rate applies in your accounting period

Work out how many days each rate applied, then work out the tax due for each.

For example, if your accounting period is 1 January 2017 to 31 December 2017 you pay:

  • the rate for the financial year starting 1 April 2016 for 90 days (1 January 2017 to 31 March 2017)
  • the rate for the financial year starting 1 April 2017 for 275 days (1 April 2017 to 31 December 2017)
