UK Tax Year Start History
UK Tax Year Start was a changing of the date in the 18th century to ensure no revenue would be lost. In 1752, to be in alignment with the rest of Europe, England decided to remove 11 days from September. The British Treasury, wanting to ensure no tax revenue was lost, added these 11 days at the end of the year. This decision caused the tax year in 1753 to be moved to 5 April.
In 1800 however, one more adjustment was made. To make up for the differences between the Julian and Gregorian calendars, the British Treasury counted 1800 as a leap year, thus making 6 April the new date of the tax year. UK Tax Year starts annually on 6 April.
