What reason did parliament give for raising taxes after 1763?

Parliament raised taxes after 1763 primarily to help pay off the debts incurred during the Seven Years' War and to cover the costs of maintaining British troops in North America. They believed that the American colonies should contribute to the expenses of their own defense and administration, given that the war had benefited them by securing land and resources. This fiscal policy aimed to assert greater control over colonial finances and governance, which ultimately contributed to rising tensions between Britain and the colonies.
