Britain’s higher earners should consider reviewing their pension tax relief strategy “sooner rather than later”, warns the chief executive of a large independent financial advisory organisation.

The warning comes from Nigel Green, deVere Group CEO and founder, and follows some suggestions that the Chancellor could slash pension tax relief as early as this month, according to deVere.

Mr Green said: “Let’s be clear: this is a tax raid - and the time to act is now for those who could be affected.

“George Osborne has already signalled plans to change existing pension tax breaks in the next Budget. The Annual Allowance will be slashed from £40,000 to £10,000 for many higher earners and there will be hefty tax charges for anyone who goes over the threshold.

Mr Green believes that the Chancellor might bring these plans forward to help plug a hole in the Budget. As such, those on higher incomes should review their strategy sooner rather than later to help mitigate being stung and to make the most of their retirement savings, he says.

He added: “I expect many top earners will want to act ahead of this month’s Spending Review. Many might consider making a larger one-off contribution in order to benefit from the higher tax relief.”

Mr Green continued: “The slashing of pension tax breaks is yet another depressingly familiar hammer blow for those wanting to get ahead in life through hard work and prudently saving for their future.

“It penalises saving when it has never been more important to do so and as it increasingly becomes a personal responsibility. We’re all living longer, meaning savings need to last longer, debt levels are high, care and health costs are climbing, and there’s a considerable reduction in the generosity of both state and private pensions.

“Given these factors, and the consequences for the country and for families of an increasingly older population with few financial resources, it seems madness to discourage savings in any way. Indeed, we need to do everything we can to revitalise a strong, long-term savings culture.”
