Pay as you earn income tax introduced for the first time in scotland

Devised by Sir Paul Chambers, PAYE was introduced into the UK in 1944, following trials in 1940–1941. As with many of the United Kingdom’s institutional arrangements, the way in which the state collects income tax through PAYE owes much of its form and structure to the peculiarities of the era in which it was devised.

The financial strain that the Second World War placed upon the country meant that the Treasury needed to collect more tax from many more people. This posed significant challenges to the government and to the many workers and employers who had previously never come into contact with the tax system.
