Which group paid the least in taxes under the old regime?

Under the old regime, the group that typically paid the least in taxes was often the nobility and clergy, who enjoyed various exemptions and privileges. This was due to their significant influence and power within the societal structure, allowing them to avoid many tax obligations that burdened the lower classes, particularly peasants and urban workers. As a result, the tax burden disproportionately fell on the lower socioeconomic groups.
