Charge to corporation tax

The company will pay corporation tax on its profits. For most sole traders there should be a significant reduction in the tax charged on the business profits compared with income tax rates of up to 45% and NIC. This is discussed further in the Calculating the tax benefits of incorporation guidance note.

There is no income tax on ‘undrawn’ profits in a company. In contrast, sole traders pay income tax on the profits of the business, irrespective of the level of their personal drawings.

Dividends are not deductible expenses in computing the company’s profits, but salary and related NIC payments are. For details, see the Allowable deductions for employee related expenses guidance note.
