The official start of the new tax year has sparked a fresh battle between Labour and the Conservatives over their respective economic plans.
David Cameron says 94% of working households are better off under tax and benefit changes brought in on Monday.
However, Labour’s Ed Balls claims the result is that families are on average £1,100 a year worse off than in 2010.
Both parties say their rivals have secret plans to raise taxes if they win the general election.
So your TAX Allowance does exactly what???
