The UK tax year traditionally starts on April 6 due to historical changes in the calendar system. In 1752, Britain switched from the Julian to the Gregorian calendar, which resulted in an 11-day discrepancy. To maintain the tax revenue flow, the new tax year was set to begin on April 6 (which was previously March 25 under the old system). This change ensured a seamless transition and continuity in tax collection without significant disruption to the fiscal calendar.
