France's constitutional council has given President Francois Hollande the green light to introduce a 75 per cent tax rate taking aim at the super rich. Under the new plan, which the French council found constitutional, companies will have to pay 50 per cent tax on all salaries exceeding one million euros, or the equivalent of approximately 833, 000. Including social contributions, the rate will effectively stand at 75 per cent, although the total amount will be capped at 5 per cent of a company's turnover. The levy is set to affect income earned this year and in 2014. The 'millionaire tax' could affect more than 450 companies and several football clubs, and could raise more than 200 million euros on an annual basis. The super tax, a flagship pledge in Hollande's political manifesto, has infuriated business leaders, high earners and celebrities. President Hollande, who once admitted that he dislikes the rich and has been accused of taking an anti-business stance, has fired back at critics insisting that high earners should do more to boost the country's public finances. But the super tax has sparked fears of a mass exodus of businesses, bankers and celebrities. Last year, Prime Minister David Cameron said he would roll out the red carpet" and "welcome more French businesses to Britain" if Hollande raised taxes on the wealthy.
