An increase in the corporation tax rate for the current tax year would ensure that those companies who unnecessarily furloughed staff and made a large profit in part repay the furlough costs, while companies who struggled won't be as affected.
The increases are always talked about in terms of individuals, while the corporation tax rates have been falling for years.
Unfortunately, we had to reduce CT rates to be competitive with other European countries. Many larger firms moved their head offices to Ireland to benefit from Irish low corporation tax rates. It's also the reason there are so many firms based in Isle of Man, Switzerland, etc.
The UK has actually benefitted from higher CT revenues as the rates have lowered over the years suggesting firms are relocating to the UK or at least staying in the UK.
It's not a Tory thing either, Gordon Brown had a zero percent corporation tax rate on the first £10,000 of profits, so to some extent, that was the reason lots of the smallest businesses converted from being sole traders into limited companies!
