Corporation tax

Calculating your company's liability to corporation tax is not straightforward. The calculation starts with your company's profit [before tax] which is then subjected to a number of adjustments, add backs and deductions.

Profits up to 31 March 2012 are taxed at 26 per cent (marginal rate 27.5 per cent) while profit accruing up to 31 March 2013 are taxed at 24 per cent (marginal rate 25 per cent).

Given the minor difference in rates and for simplicity this calculator uses the lower rates for the whole of the year's profit.

Having used the calculator please contact us as we would welcome the opportunity to discuss reducing this provisional liability.

Please continue and enter values using the following options.

Company details

  1. Corporation tax is normally payable nine months and one day after the end of your financial year.
  2. Depreciation is one of those items in your profit and loss account that is not an allowable cost for corporation tax purposes.
  3. Tax relief is available for certain capital expenditure. This calculator only allows for capital expenditure incurred during the year you are looking at.
