How long you should keep money in an ISA depends on the type, but generally, you should plan for at least 5 years for Stocks and Shares ISAs to ride out market volatility. Cash ISAs are suitable for shorter periods, while money can remain tax-free in any ISA for as long as you keep it there.
Stocks and shares ISAs, and investment ISAs, allow you to have access to your money at any time. Investing may be more appropriate if you're looking to invest for the medium-long term, which would be 5 to 10 years.
If you're not paying tax on your savings interest, cash ISAs have no benefit – so many should ditch them for higher-paying standard accounts. That's the message from MoneySavingExpert.com founder Martin Lewis in the third episode of the latest series of ITV's The Martin Lewis Money Show Live.
Can I put more than £20,000 in an ISA? Technically, yes, but not all at once. There's no limit to how much money can be in an ISA. The ISA allowance limit applies to how much you can pay in during each tax year (6 April to 5 April the following year).
Individual Savings Accounts (ISAs)
The government sets a maximum amount that you can invest in ISAs. Until 2031 the annual limit is £20,000. You pay no Income Tax on the interest or dividends you earn within an ISA and any profits from investments are free of Capital Gains Tax.
Along with the tax savings, another big ISA perk is that you don't need to declare any income or capital gains generated by your ISA investments on any tax return. And while HMRC has proposed new rules to charge interest paid on cash held in Stocks and shares ISAs, it didn't use the 'tax' in its announcement.
The HMRC document also said there were around 3,080 Isa accounts with a market value of £1 million-plus in 2022/23. It counted 30 cash Isa accounts with £500,000-plus in them and 38,680 stocks and shares accounts containing at least £500,000 in the tax year 2022/23. The figures were rounded to the nearest 10.
The 7-3-2 rule is a financial strategy for wealth building, suggesting it takes 7 years to save your first major financial goal (like a crore), then accelerating to achieve the next goal in 3 years, and the third goal in just 2 years, leveraging compounding and disciplined, increased investments (like a 10% annual SIP hike). It highlights how returns compound faster over time, drastically reducing the time needed for subsequent wealth targets, emphasizing patience and consistent, growing contributions.
As widely expected, Chancellor Rachel Reeves has taken an axe to the annual cash ISA allowance in a bid to encourage UK savers to invest. In Wednesday's Autumn Budget Reeves announced the £20,000 annual cash ISA allowance would fall from £20,000 to £12,000, from April 2027.
The 70/20/10 rule for money is a simple budgeting guideline that splits your after-tax income into three categories: 70% for Needs (essentials like rent, groceries, bills), 20% for Savings & Investments (emergency funds, retirement), and 10% for Debt Repayment & Donations (extra debt payments or giving). It balances immediate living costs with long-term financial security, helping you cover necessities while building wealth and paying off liabilities.
You can get around 7% interest on savings in the UK primarily through Regular Saver accounts, with top offers from Zopa (7.1% variable), First Direct (7% fixed), and the Co-operative Bank (7% variable), though these often require you to have their current account and limit monthly deposits, while Principality Building Society has offered rates near this (7.5%) on fixed-term savers, so check MoneySavingExpert and MoneyWeek for current deals.
Disadvantages: Interest rates may decrease, funds might be locked in fixed-rate ISAs, and not all accounts permit transfers, sometimes incurring exit fees.
What were the Cash ISA changes announced in the Autumn Budget? The Budget confirmed that the Cash ISA allowance is set to be cut from April 2027. For under-65s, the Cash ISA allowance will reduce from £20,000 to £12,000. For 65s, and older, the Cash ISA allowance will remain at £20,000.
The UK government has announced significant changes to the tax treatment of cash held within stocks and shares Isas, targeting a loophole that could allow savers to bypass newly imposed caps on tax-free cash savings.
Currently, you are able to contribute up to £20,000 each tax year into a cash ISA (or you can split this allowance between other types of ISA). However, the Chancellor has confirmed the cash ISA limit will be reduced to £12,000 a year from April 2027.
To avoid the UK's 60% tax trap (an effective 60% rate on income between £100k-£125k), the key is to reduce your adjusted net income back below £100,000 by making tax-efficient contributions, primarily via pension contributions, which reclaim your full £12,570 Personal Allowance, and also through salary sacrifice for benefits like childcare or cycle-to-work, and Gift Aid donations to charity.
The "6-year rule" for Capital Gains Tax (CGT) in Australia allows you to treat a former main residence as tax-exempt for up to six years after you move out, even if you rent it out, enabling you to avoid CGT on any growth during that period. You qualify by moving out, choosing to treat it as your main home for tax, and can reset the rule by moving back in. If you rent it out for longer than six years, only the portion of the gain after the six-year mark becomes taxable.
