In 2006 a major change was implemented in France regarding the income tax. Not only the top marginal rate was lowered (from 48.09% to 40.00%), but the same treatment was applied to the other rates. Also, the number of brackets was reduced from 7 to 5. As a result, whatever the level of taxable income, the rate applied was lower after the changes took place than before. Pierre Garello shows the impact of those tax cuts on tax revenues.
