What ISA changes are coming?

The Government has announced that, from April 2027, a 22% charge will apply to interest earned on cash held within non-cash Individual Savings Accounts (ISAs), such as Stocks & Shares ISAs and Innovative Finance ISAs.

This change follows ongoing calls from ISA providers and investors for greater clarity on how cash held within these types of accounts would be treated for tax purposes.

Reduced cash ISA allowance

This also comes after last November’s Budget, which confirmed a reduction to £12,000 in the annual tax-free Cash ISA allowance for those under age 65 from next April.

The annual stocks and shares ISA allowance will remain at £20,000.

Why is the Government changing ISA rules?

As a nation, the UK population invests less than other developed countries, and our personal wealth is suffering as a result.

In the UK, only 23% of people have invested in the stock market. In the US, it’s almost two thirds.

The Government hopes these changes will encourage more people to invest rather than keep cash in savings.

While the value of investments can fall as well as rise, over the long term, investments have generally delivered stronger returns than cash, which can lose value over time due to inflation.

What can I do about this?

It’s completely understandable to feel unsure about investing, with many people viewing cash as a ‘safe’ option.

However, over time, the effects of inflation can reduce the spending power of money held in cash.

With so many investment options available, it’s easy to feel uncertain about where to start.

How can a financial adviser help?

This is where seeking professional advice can really help.

A financial adviser will take the time to understand your individual circumstances, as well as your financial and personal goals, and provide tailored recommendations to help you make the most of your money – for you and your family.

What is happening to the Lifetime ISA?

The Government has launched a consultation on a new ‘First Time Buyer ISA’. This is in response to the average age of first-time buyers rising, and the current Lifetime ISA product having an upper age limit of 40 for new savers.

The new ISA will still include a 25% government bonus, but this will now be paid when scontracts are exchanged on your first home, rather than added each year.

Importantly, the previous 25% withdrawal penalty will be removed, meaning you won’t lose part of your original savings if you need to take the money out for another reason.

Will the £450,000 property price cap change?

The new proposed product does appear to address some of the issues with its predecessor, but an important point of note is that the consultation has not yet addressed the £450,000 price cap.

This was originally set in 2017 when the Lifetime ISA was launched, with the Government stating that the limit ensures the support goes to those that need it most.

What happens next?

We will be watching the consultation closely for further developments.

ISA changes FAQs - what you need to know

What ISA changes are being introduced in 2027?

The Government plans to introduce a 22% charge on interest earned from cash held within non-cash ISAs, such as Stocks & Shares ISAs and Innovative Finance ISAs, from April 2027.

Will Cash ISAs still be tax-free?

Cash ISAs will continue to offer tax advantages, but annual allowance changes have been announced, with reduced limits for some savers.

Why is the Government changing ISA rules?

The Government aims to encourage more people to invest rather than hold large amounts of cash in savings accounts, helping individuals potentially achieve higher long-term returns.

How does inflation affect cash savings?

Inflation reduces the purchasing power of money over time. If savings growth does not keep pace with inflation, the real value of those savings falls.

Should I move money from cash savings into investments?

The right approach depends on your goals, risk tolerance and time horizon. Professional financial advice can help determine the most suitable strategy for your circumstances.

What is replacing the Lifetime ISA?

The Government is consulting on a new First Time Buyer ISA, which would retain a 25% government bonus while removing the existing withdrawal penalty.

Will the £450,000 Lifetime ISA property limit change?

At present, the consultation has not proposed changes to the £450,000 property price cap, although this may be reviewed as the consultation progresses.

The annual Stocks and Shares ISA allowance is expected to remain at £20,000.
