He kept to the old system of revenues from the demesne and from imposts that were reactionary in their effect, such as the taille, aids, salt-tax (gabelle) and customs; only he managed them better.
The elus and the superintendents, instead of being delegates of the states, became royal functionaries like the baillis and the provosts; imposts, hearth-money (fouage), salt-tax (gabelle), sale-dues (droits de vente), voted for the war, were levied during the whole of Charles V.s reign and added to his personal revenue.
The same year he published a pamphlet against feudal aids and the gabelle, for which he was denounced and arrested, but provisionally released.
