His father's family were bourgeois cloth merchants and manufacturers established in Montolieu and said to have originated from Nogaret, Haute-Garonne.

Most important, he was king's advocate in the maréchaussée and presidial seat of Carcassonne, a position he received from his great uncle, Louis-Joseph Benazet.

Ramel de Nogaret intervened in a considerable number of discussions, including those on the Constitution of 1793, on sale of the property of émigrés, creation of assignats and distribution of taxes.

[3] Ramel de Nogaret was made a member of the Committee of Public Safety, and proposed establishment of a "paternal Commission" to take the final decision on the guilt of the accused before sending them to court.

[5] Due to the special study Ramel had made of tax issues, on 25 Pluviôse IV (14 February 1796) he was appointed Minister of Finance.

In Brumaire VI (November 1797) he established taxation agencies in the departments with commissioners, tax collection staff and an inspector.

[2] However, the disorders in tax administration towards the end of the Directory, for which he was not responsible, made him the target of anger for all the problems of the country.

However, Ramel de Nogaret was no richer when he retired from power on 2 Thermidor VII (20 July 1799) than when he entered office.

After the second Bourbon Restoration, in January 1816 he was exiled as a regicide, and settled in Belgium, where he returned to his family's business of textile manufacture and trade.

[2] In 1820 the celebrated painter Jacques-Louis David (30 August 1748 – 29 December 1825) made portraits of Ramel and his wife, Ange-Pauline-Charlotte.
