If you are a limited company or an unincorporated association, such as a club or co-operative, then your taxable profits are subject to corporation tax. If a foreign company has an office or department in the United Kingdom then they are subject to Corporation Tax on all of the profits they make from their activities in the United Kingdom.

As of the 1st of April in 2015, Corporation Tax has risen to 20%, although in July of 2015 the Chancellor announced that based on budgets, the rate of Corporation Tax will drop to 19% in 2017 and 18% in 2020.

Tax Year: a regular government tax year starts on April the 1st and ends on the 31st of March of the next year. If it so happens that your companies financial year differs from the government's financial year then the necessary tax will be calculated proportionally against the government's tax year period.
