Pronunciation

Forms

impôt m (plural impôts)[1] Middle French impost, also impos; the spelling impôt is recorded by Richelet in 1680.[2][3]

Etymology

It is borrowed from Latin impositum (“that which is imposed”), the neuter past participle, used as a noun, of impōnō (“to place upon, to impose”).[4][5][6][7] The borrowing was adapted to French on the model of dépôt.[5][6][8] Wiktionary instead presents Old French impost as the source, a syncopated form of the Latin participle.[1] The verb imposer belongs to the same Latin family.[4][9]

Earliest recorded meaning

It is first recorded in 1399, as impost, for the share of public expenditure that the state laid on each subject.[4][5][6] A 15th-century record speaks of impos et collectes imposed on the people.[2]

Semantic evolution

Under the Ancien Régime the levy could be in kind (forced labour, the tithe) or in money (the aide, the poll tax, the salt tax, the taille).[5] Littré notes that the word was once given only to temporary levies imposed for the needs of the state.[2] In 1767 l'impôt is found for the whole of these charges, and in 1768 the economists distinguished impôts indirects from direct taxes.[4][5]

Figuratively, from Lamennais (1817–1823), it means any contribution or obligation, and Balzac's l'impôt du sang (1842) is the duty of military service.[4][5] In the 19th century the plural les impôts came to name the tax administration, as a synonym of fisc.[5]
