What is Corporation Tax?

Corporation tax is the UK term for the tax levied on company profits. The main rate is 25%, with a reduced rate of 19% for companies with profits under GBP 50,000.

Corporation tax is calculated on a company's taxable profits for the accounting period. In the UK, the main rate is 25% for companies with profits over GBP 250,000. Companies with profits under GBP 50,000 pay the small profits rate of 19%. Those between GBP 50,000 and GBP 250,000 pay a marginal rate. Companies must register with HMRC for corporation tax within three months of starting to trade. The corporation tax return must be filed within 12 months of the accounting period end, and payment is due 9 months and one day after the period end. Large companies may need to pay quarterly instalment payments. Calculating corporation tax involves adjusting accounting profit for tax purposes - adding back non-deductible expenses and deducting capital allowances.
