Claim: There was an £8 billion increase in revenues from additional rate taxpayers after the top rate of tax was reduced from 50p to 45p.
Fact-check: Did cutting the 50p rate of tax raise £8 billion? - Full Fact
Verdict: revenues did increase by that much, but tax receipts were artificially low in 2012/13 and artificially high in 2013/14 due to people 'deferring' income from one tax year to another in order to benefit from the lower tax rate. so this can't be described as the amount of money raised by the reduction in the rate.
