THE PM will today hail “the single biggest tax cut in a decade” months after raiding workers’ hard-earned cash.
Boris Johnson claims 30million will be £330 a year better off when National Insurance thresholds change tomorrow.
But it comes after he raised the NI rate by 1.25 per cent in April.
The increase in the threshold means workers will start paying NI contributions only on earnings above £12,570.
Mr Johnson said: “Tomorrow is an important moment . . . as the single biggest tax cut in a decade comes into force.
“The list of people who will benefit is vast — from hairdressers and care workers to receptionists.”
He also promised “more tax cuts in the future”.
