After the Second World War, the tax system underwent a certain number of reforms aiming at modernizing and adapting it. The income tax was adapted and old contributions abolished. A family quotient was created in 1945. The business tax was created in 1948, reformed in 1959. Finally, the last significant innovation in technical terms, the VAT was introduced in 1954. Then the French example was adopted gradually in most developed countries. The French tax system is currently controversial with the development of the European Union and globalization. Tax competition has risen sharply, and it becomes necessary to take into account the legal possibilities to avoid paying taxes (the practice of expatriation is legal, unlike tax evasion).
