In 1959, self-government took place and the Inland Revenue Department was formed in 1960 when various revenues which were previously administered and collected by a number of separate agencies were brought together. When Singapore achieved independence in 1965, the Income Tax Act saw substantial changes take place, all of which came into effect on the 1st of January 1966.
