How does the corporation tax calculator work?

If you run a limited company, you’ll need to pay Corporation Tax on your profits – minus any reliefs you claim. The current rate of Corporation Tax is 19%. There is no ‘personal allowance’ as there is with income tax and dividends – meaning all profits are taxable. 

How much Corporation Tax you pay will be calculated based on your net trading profit during the company’s financial year in question – or accounting period as its known. 

As this tax is calculated on your profits, you’ll need to work out what your net trading profit is for this period. This may differ from the profit in your profit and loss account as there may be some items which are not allowed for Corporation Tax purposes. Our guide to calculating profit will help you arrive at this figure – and we also recommend consulting with your accountant.
