What could a new Prime Minister mean for your savings?

A new Prime Minister often brings renewed speculation about taxes, pensions and savings. With Andy Burnham now in Downing Street and Chancellor John Healey preparing for his first Budget, attention has quickly turned to what the new government could mean for household finances.

What could a new Prime Minister mean for your savings?

Andy Burnham has long argued that Britain relies too heavily on taxing work and too lightly on taxing wealth. While he has not announced a wealth tax or detailed reforms to the taxation of private assets, his government inherits an economy facing difficult choices.

Sluggish growth, rising spending pressures on healthcare, pensions, defence and infrastructure and stretched public finances mean that every Chancellor will be looking carefully at how future spending is funded and where future tax revenue comes from.

For savers and investors, this creates uncertainty. Capital Gains Tax, Inheritance Tax, property taxation and investment income are all areas that could remain under scrutiny over the coming years. While headlines may be worrying, it’s worth remembering that tax policy takes time to develop and must pass through Parliament before becoming law.

Britain remains an attractive place to invest, however, accumulated wealth could play a larger role in funding the nation's finances over the coming years. This matters not only for the wealthy, but for millions of households whose biggest assets are their savings, pensions, investments and property. Any future changes to how those assets are taxed could affect long-term returns and financial planning.

Against that backdrop, making full use of the tax allowances available today has rarely been more important. Whether you're holding cash for the short term or investing for the long term, ensuring as much of your money as possible sits inside tax-efficient wrappers, such as a Cash ISA, can help protect more of your returns from whatever tax changes lie ahead.

Use today's allowances while you still can

One of the biggest changes already on the horizon has nothing to do with the new government. From 6 April 2027, the maximum amount that under-65s can pay into a Cash ISA each tax year will reduce from £20,000 to £12,000.

For anyone holding significant cash, that makes this tax year particularly valuable. Using as much of your current Cash ISA allowance as you can means more of your savings will continue to grow free from income tax on interest, regardless of what future governments decide.

If you’re saving towards a house purchase, building an emergency fund or simply waiting for investment opportunities, making full use of today's allowance could prove far more valuable than trying to second-guess tomorrow's tax policy.

Review your wider tax planning

Political change is also a useful reminder to review your broader financial plan. Frozen income tax thresholds continue to draw more people into paying higher rates of tax through fiscal drag, where inflation pushes up wages but not tax thresholds.

Meanwhile, from 6 April 2027, unused defined contribution pensions are expected to form part of an estate for Inheritance Tax purposes, changing the way many families think about retirement and estate planning.

Many retirees are now reviewing how and when they access their tax-free pension lump sum, particularly in light of the planned Inheritance Tax changes. While a pension remains one of the most tax-efficient ways to save for retirement, taking tax-free cash forms part of a much wider financial plan than it once did.

Equally important is making sure any money you do withdraw continues to work for you. Leaving a large pension lump sum or inheritance sitting in a low-interest current account could mean your savings gradually lose value in real terms while potentially generating taxable interest.

A savings platform like Flagstone enables you to access hundreds of high-interest accounts all through one platform, helping your pension tax-free lump sum earn a competitive return while keeping your options open.

EXPLORE BANKS AND RATES

While a new government may revisit some of these measures, with Andy Burnham hinting at addressing the personal tax-free threshold, planning based on rules that don't yet exist rarely pays. Instead, focus on making the most of the allowances and reliefs that are available today.

That means reviewing how your savings are split between taxable accounts and tax-efficient wrappers such as Cash ISAs, ensuring your cash is earning a competitive rate of interest and considering how your pension fits into your longer-term financial plans.

Don’t let political change delay good financial decisions

No one can predict exactly how the tax system will evolve over the next Parliament. But your financial goals are unlikely to change. Protecting your savings from unnecessary tax, earning a competitive return on your cash and making full use of available tax-efficient allowances remain sensible financial habits regardless of who occupies Downing Street.

Governments will continue to change tax policy over time. The best response isn’t to try to predict every Budget announcement but rather to make today’s rules work as hard as possible for your own finances.
