UK Tax Year Start History
UK Tax Year Start was a changing of the tax date in the 18th century to ensure no revenue would be lost for the Royal Crown. In 1752, to be in alignment with the rest of Europe, England decided to remove 11 days from the month of 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, one more adjustment was made to the UK Tax Year. To make up for the differences between the Julian and Gregorian calendars, the British Treasury counted the year 1800 as a leap year. This made 6 April the new date of the tax year. The UK Tax Year continues to be observed annually on 6 April.
