Corporation Tax rate before 1st April 2023
Before 5th April 2025, HMRC charged a flat rate of just 19% corporation tax on the profits made by a UK limited company. This 19% corporation tax flat rate was competitive throughout Europe. The 19% corporation tax rate was also very competitive against sole traders.
Sole traders paid an income tax rate of 20% for basic rate taxpayers, 40% for high rate taxpayers and 45% for additional rate taxpayers. In addition to income tax, sole traders would pay National Insurance class 2 and National Insurance class 4. An additional stealth tax.
Calculating the 19% corporation tax rate on UK limited companies was also straightforward. You did not need to use online calculators to perform this tax calculation. It is simple enough to do yourself.

Any UK limited company that generates a profit of £50,000 or less would remain at the UK corporation rate tax of 19%. There is no change for these directors/shareholders of a UK limited company. There is no need to use an online calculator to see how much more tax you will pay after 1st April 2023, as there is no difference.
