Corporation Tax is a direct tax that is applied against companies that operate in the UK, this includes corporations, limited companies, limited company contractors etc. If a company is based in the UK it pays corporation tax on all its profits from within the UK and abroad. If a company is based outside the UK but has a branch or office in the UK it must pay corporation tax on all profits from UK business activities.
Corporation Tax in 2018 is calculated based on the profits that fall within the 2018 tax year. 2018 Corporation tax is applied against those profits using the standard rate of corporation tax in 2018.
It is important to note that the corporation tax rate applies across the tax ear as defined by HMRC (April 1st 2018 to March 31st 2019, not a companies financial year which is most often different to the UK Tax Year. When a companies financial year bridges two tax years, the profits must be broken down into two separate tax periods and the appropriate corporation tax rate and thresholds applied on a pro-rata basis
Taxes, including corporation tax, expenses and limitations are reviewed by the Government in the United Kingdom periodically and typically updated each year. Note that not all tax rates and thresholds in the United Kingdom change annually, alterations to tax policy to support strategic economic growth in the United Kingdom mean that the certain areas may be focused on to provide specific tax relief in the United Kingdom or support growth in certain areas (overseas investment in the United Kingdom for example may mean reduced non-resident income tax rates in the United Kingdom for a period). Corporation tax is administered by Her Majesties Revenue and customs (HMRC) who promulgate updates to corporation tax and other taxes as policies are altered and tax laws change.
When tax policy in the United Kingdom changes, the resultant tax tables also change, HMRC then publishes new Tax tables and information on changes to UK tax law and computations.
