Corporation Tax Rates, Reliefs & Returns

What is corporation tax?

Corporation tax is payable by UK limited companies on profits generated.

Corporation tax applies to the profits generated by a company from:

  • Sale of goods and services
  • Investments
  • Sale of business assets (‘chargeable gains’)

Corporation tax on chargeable gains

If a company sells or disposes of a business asset at a profit, this profit will be subject to corporation tax.

Business assets are those owned by the company, which could include shares, property and land as well as items such as equipment and machinery.

Gains on intangible assets such as IP and business reputation acquired or created by the company after 31 March 2002 should be included in the company’s trading profits and are also subject to corporation tax.

To calculate the tax liability, you will need to determine the value of the gain resulting from the disposal, less any reliefs or allowances, and then apply the current corporation tax rate.

Chargeable gains are to be reported to HMRC with your annual company tax return.

The equivalent tax for the self-employed is capital gains tax.

What is the UK corporation tax rate?

The main rate for UK corporation tax in 2020/2021 is 19%. This has been at the same level since 2015. The corporation tax year starts 1st April.
