Throughout the 19th century, taxes changed little. Taxes from the Revolution remained, i.e. taxes on wealth (Impôt sur la fortune) on the professional activity (the patente, ancestor of the taxe professionnelle), and many indirect taxes and "droits" applied to the trade of goods (inheritance, purchase of real estate). From the middle of the 19th century, there were debates for the creation of an income tax, proposed by Proudhon in 1848, then by Gambetta in 1869. In 1872, a tax on incomes from real estate was created. In 1876, Gambetta proposed to create a proportional tax on all incomes. The only result is the creation in 1896 of a tax on incomes from the stock exchange.
