Time to ditch corporation tax.
It has become a tax which only locally owned and registered businesses pay.
There is no effective way to apply this tax fairly so that British owned and registered company pays the same rate as a foreign owned multi-national.
Just look at how much tax Cadburys paid when they were a British registered PLC making chocolate compared with the tax they paid as a subsidiary of an American brown sugary fat manufacturer.
The only fair thing is to scrap the tax and allow local companies to compete with multinationals on even terms.
