Your cash ISA is full, what next?

As a responsible saver, you’ve likely embraced the power of a Cash ISA to shield your hard-earned interest from the taxman.

It’s a fantastic tool for short-term savings and emergency funds. But what happens when you’ve hit the annual £20,000 limit, and you still have money you want to put aside?

Reaching your Cash ISA limit is a sign of great financial discipline! It means you’re doing an excellent job of saving.

But what’s next?

This guide is for you if you’ve maxed out your cash ISA and are wondering where to put your extra cash.

We’ll explore various options, from other tax-efficient accounts to different investment avenues, helping you understand the pros and cons of each.

My goal is to equip you with the knowledge to make informed decisions that align with your financial goals and risk tolerance.

Understanding your ISA allowance

Understanding your ISA allowance is crucial as it helps you navigate your options effectively.

Your ISA allowance for the current tax year is £20,000. The tax year runs from April 6th to April 5th the following year. This is your total allowance across all types of ISAs.

You can split this allowance any way you choose.

For example, you could put the full £20,000 into a Cash ISA. Or you could put £10,000 into a Cash ISA and £10,000 into a Stocks and Shares ISA.

You can even pay into multiple types of ISAs in the same tax year.

Just make sure your combined contributions don’t go over the £20,000 limit.

It’s important to remember that your ISA allowance resets each new tax year and you cannot carry over any unused allowance.

If you don’t use your full £20,000 by April 5th, that portion is gone forever. This is why many people try to “use it or lose it” with their ISA allowance.

Prep steps:

• Check your current Cash ISA contributions for the tax year. Most providers show this clearly online or in statements.
• Understand when the current tax year ends (April 5th).

Best practices/helpful tips:

• Plan ahead: If you think you’ll hit your ISA limit, research other options beforehand. This gives you time to understand your choices.
• Maximise your allowance: Even if you don’t have £20,000 to save, try to use as much of your ISA allowance as you can. Over time, these tax-free savings add up significantly.
• Consider a “Bed and ISA” if investing: This is for investors. You sell existing investments from a taxable account. Then you immediately buy them back within a stocks and shares ISA. This uses your ISA allowance. It also protects future gains from capital gains tax.

(Always get professional advice for complex tax planning.)

Tools or resources:

• Your ISA provider’s online portal: This is the best place to check your current contributions. See how much of your allowance you’ve used.
• GOV.UK website: This official government website has comprehensive and up-to-date information on ISA rules and allowances.

When your Cash ISA is full, you’ve filled that tax-efficient bucket, but your saving journey doesn’t have to stop.

It’s just time to find other ways to make your money work hard.

Look at Other ISA Types

Once your Cash ISA is maxed out, remember that your overall £20,000 ISA allowance can be spread across different types of ISAs.

This is where other ISA wrappers come into play, offering different benefits depending on your financial goals and attitude to risk.

Stocks and Shares ISA

A stocks and shares ISA allows you to invest in a wide range of assets, such as company shares, funds, investment trusts, and bonds.

The key difference here is that your money is invested, not just held as cash.

This means there’s a potential for higher returns over the long term, but also a risk that the value of your investments can go down as well as up.

If you’re saving for a goal that’s more than five years away, like a pension top-up, a house deposit (if you’re not using a Lifetime ISA), or general wealth building, a stocks and shares ISA can be a powerful tool.

The growth and income generated from your investments within this ISA are completely free from UK income tax and capital gains tax.

Prep steps:

• Understand your risk tolerance: Investing has risks. Think about how comfortable you are with your money’s value potentially fluctuating.
• Define your investment goals: Are you saving for retirement? A specific large purchase? Something else? Your goals influence your investment choices.

Best practices/helpful tips:

• Diversify your investments: Don’t put all your eggs in one basket. Spread investments across different companies, industries, and regions to reduce risk.
• Invest for the long term: The stock market can be volatile short-term. Historically, long-term investors ride out ups and downs and tend to see better returns. Aim for at least five years, preferably longer.
• Consider readymade portfolios or tracker funds: If you’re new to investing, these are great starting points. Readymade portfolios are designed by experts for different risk levels. Tracker funds (like those tracking the S&P 500) aim to mirror a specific market index.

Tools or resources:

• Investment platforms: Companies like Vanguard, Hargreaves Lansdown, AJ Bell, and Fidelity offer stocks and shares ISAs. They provide tools and resources to help you choose investments.
• Financial advisors: If you’re unsure about investing, a qualified financial advisor can give personalised advice.

Lifetime ISA (LISA)

The Lifetime ISA (LISA) is more specific. It helps those aged 18 to 39 save for their first home or retirement.

You can save up to £4,000 each tax year into a LISA. The government adds a 25% bonus to your contributions, up to £1,000 per year.

This £4,000 counts towards your overall £20,000 ISA allowance.

You can hold cash or stocks and shares within a LISA. The major catch: if you withdraw money for reasons other than buying your first home (up to £450,000) or reaching age 60 (or being terminally ill), you’ll face a 25% withdrawal charge.

This recovers the government bonus and a bit more.

Prep steps:

• Are you eligible? You must be 18-39 to open one. Make your first payment before you turn 40.
• What’s your goal? Is it specifically for a first home or retirement? If not, a LISA might not be suitable due to penalties.

Best practices/helpful tips:

• Max out the bonus: If eligible and saving for a first home or retirement, try to contribute the full £4,000 each year to get the maximum £1,000 government bonus.
• Understand the penalties: Be clear on withdrawal penalties before committing to a LISA.

Tools or resources:

• GOV.UK Lifetime ISA guide: This is your definitive source for all rules and conditions.
• Providers of LISA accounts: Many banks and investment platforms offer LISAs, often with cash or investment options.

Innovative Finance ISA (IFISA)

An Innovative Finance ISA allows you to lend money directly to individuals or businesses through peer-to-peer (P2P) lending platforms.

The interest you earn on these loans is tax-free within the IFISA wrapper.

IFISAs are generally considered higher risk than Cash ISAs and even some stocks and shares ISAs.

The main risk is that the borrowers may default on their loans, meaning you could lose some or all of your capital.

Unlike traditional savings accounts, P2P investments are not covered by the Financial Services Compensation Scheme (FSCS).

Prep steps:

• Thoroughly research P2P platforms: Look into their track record, default rates, and how they reduce risk.
• Understand the specific risks: P2P lending has its pitfalls.

Best practices/helpful tips:

• Diversify across platforms and loans: Don’t put all your IFISA money into one platform or one loan. Spread your risk.
• Only invest what you can afford to lose: Given the higher risk, it’s wise to be cautious.

Tools or resources:

• FCA Register: Check if the P2P platform is regulated by the Financial Conduct Authority.
• MoneyHelper website: Provides a good overview of P2P lending and its risks.

Exploring other ISA types can help you continue saving and potentially grow your money in a tax-efficient way once your cash ISA is full.

Each has its own risk profile and suitability, so consider your circumstances carefully.

Exploring Non-ISA Savings Options

Even after exhausting your ISA allowance, you still have options for your savings.

While these accounts don’t offer the same tax-free benefits as ISAs, they can still be valuable tools for managing your money.

Regular Savings Accounts

These are standard savings accounts offered by banks and building societies.

They don’t have the tax-free wrapper of an ISA, meaning any interest you earn will be subject to income tax if it exceeds your Personal Savings Allowance (PSA).

The PSA allows basic rate taxpayers to earn up to £1,000 in interest tax-free each year.

Higher rate taxpayers have an allowance of £500, and additional rate taxpayers have no PSA.

If your interest earnings go above your PSA, you’ll need to pay tax on the excess at your marginal income tax rate.

Regular savings accounts can be a good option for short-term savings goals or for a rainy day fund, as many offer easy access.

Some accounts may offer slightly higher interest rates if you commit to saving a certain amount each month.

Prep steps:

• Know your Personal Savings Allowance: Understand how much interest you can earn before it’s taxed.
• Compare interest rates: Rates on regular savings accounts vary a lot. Shop around for the best deals.

Best practices/helpful tips:

• Prioritise your ISA allowance: Always fill your ISA allowance first. It offers the most generous tax benefits.
• Monitor your interest: Keep an eye on how much interest you’re earning in taxable accounts. Make sure you don’t accidentally go over your PSA.
• Laddering fixed-term bonds: If you have a lump sum and don’t need immediate access, consider fixed-term bonds. Spread your money across bonds with different maturity dates (e.g., 1-year, 2-year, 3-year). This ensures some money becomes accessible regularly. You can also benefit from potentially higher fixed rates.

Tools or resources:

• Comparison websites: Use sites like MoneySavingExpert, Comparethemarket, or GoCompare. Find the best savings account rates.
• Bank and building society websites: Check directly with providers for their latest offerings.

Premium Bonds

Premium Bonds, offered by National Savings and Investments (NS&I), are a unique savings product.

Instead of earning interest, your money is entered into a monthly prize draw where you can win tax-free prizes ranging from £25 to £1 million.

While there’s no guaranteed return, all prizes are tax-free.

You can invest up to £50,000 in Premium Bonds. They are considered very low risk because your capital is 100% secure as NS&I is backed by HM Treasury.

You can withdraw your money at any time, usually within a few working days.

Prep steps:

• Understand the prize draw: There’s no guaranteed return. Be comfortable with possibly winning nothing.
• Consider your savings goals: If you need guaranteed growth for a specific goal, Premium Bonds might not be best.

Best practices/helpful tips:

• Use them for some cash savings: They’re good for money you want accessible. But you don’t need it to grow at a fixed rate.
• Don’t rely on them for income: Prizes are random. They aren’t good for regular income.

These non-ISA options provide flexibility once your tax-free ISA allowance is fully utilised.

While they come with different tax implications, they can still play a valuable role in your overall savings strategy.

The key is to understand their features and decide if they fit with your financial objectives.

Consider General Investment Accounts (GIAs)

If your ISAs are full, and you still want to invest, a General Investment Account (GIA) is the next step.

Unlike ISAs, a GIA doesn’t offer specific tax advantages. Any profits or income from investments in a GIA will be subject to UK taxes.

However, GIAs offer unlimited investment potential, meaning there’s no cap on how much you can invest.

This makes them a popular choice for those who have maximised their ISA allowance and are looking to continue growing their wealth through investing.

What you need to do:

With a GIA, you can invest in similar assets as a stocks and shares ISA. This includes individual company shares, funds, investment trusts, and bonds.

Buying and selling investments is similar to an ISA. The main difference is the tax treatment.

Any profits you make when you sell an investment in a GIA (known as capital gains) might be subject to Capital Gains Tax (CGT).

You have an annual Capital Gains Tax allowance, which is £3,000 for the 2024/2025 tax year.

If your gains exceed this allowance, you’ll pay CGT at a rate that depends on your income tax band (currently 10% or 20% for most assets, or 18% or 28% for residential property).

Income from investments, such as dividends from shares or interest from bonds, will be subject to income tax.

You also have a dividend allowance (£500 for the 2024/2025 tax year) before income tax applies to dividends.

Prep steps:

• Understand the tax implications: Learn about Capital Gains Tax and dividend tax rules. Keeping clear records of your investments is helpful.
• Assess your investment horizon: GIAs are best for long-term investments (five years or more). You can ride out market fluctuations and potentially benefit from compounding returns.
• Review your risk tolerance: Investing always has risk. Be comfortable with the possibility that your investments could go down in value.

Best practices/helpful tips:

• Keep meticulous records: For tax purposes, you need to know your purchase price, sale price, and any costs for each investment. This is essential for calculating gains and losses.
• Utilise your annual allowances: Use your annual Capital Gains Tax allowance and dividend allowance. If you plan to sell investments with large gains, consider selling them over multiple tax years.
• Consider a tax advisor: If your GIA portfolio is large or tax situations are complex, a qualified tax advisor can be invaluable. They can help optimise your tax position.

Tools or resources:

• Investment platforms: Most platforms offering stocks and shares ISAs also offer General Investment Accounts. Examples include Vanguard, interactive investor, Freetrade, and Hargreaves Lansdown.
• HMRC website: The official government website has detailed information on Capital Gains Tax and investment income tax.

A General Investment Account gives you the flexibility to continue investing beyond your ISA limits.

While the tax benefits aren’t the same, a well-managed GIA can still be a powerful tool for long-term wealth creation, especially if you actively manage your tax position by utilising your annual allowances.

Troubleshooting investing common mistakes

It’s easy to make mistakes with your finances. This is especially true with allowances and different account types.

Here are some common pitfalls when your Cash ISA is full. And how to avoid them.

1. Exceeding your overall ISA allowance

This is perhaps the most common mistake. People sometimes mistakenly believe they have a £20,000 allowance for each type of ISA.

For example, they might put £20,000 into a cash ISA and then another £5,000 into a stocks and shares ISA in the same tax year.

This would mean they’ve oversubscribed their allowance by £5,000.

How to fix it:

• Stay vigilant: Always track your total contributions across all your ISAs. Do this in a single tax year.
• Communicate with your providers: If you have ISAs with different providers, tell them about your other ISA subscriptions. This helps avoid accidentally oversubscribing. They have systems to help but you are ultimately responsible.
• Contact HMRC if you realise you’ve oversubscribed: If you accidentally exceed your allowance, contact HM Revenue & Customs (HMRC) quickly. They will tell you how to fix it. This usually means removing the excess funds and any associated gains.

2. Withdrawing from a Lifetime ISA for an unauthorised purpose

The Lifetime ISA is a great tool, but it comes with strict withdrawal rules.

Taking money out for something other than buying your first home (under £450,000) or retirement (age 60+) will incur a 25% withdrawal charge.

This charge is designed to reclaim the government bonus and an additional penalty

How to fix it:

• Understand the rules upfront: Before opening a LISA, be sure your savings goal matches its purpose.
• Only contribute what you’re sure you’ll use for the intended purpose: If you might need the money for other reasons, a different ISA or savings account is better.
• Consider alternatives: If your plans change, explore transferring the LISA to another ISA type. For example, a Stocks and Shares ISA. This may still trigger the withdrawal charge.

3. Losing tax-free status when transferring

If you want to move money from an old ISA to a new one, you must do an official ISA transfer.

If you simply withdraw the money from one ISA and then pay it into a new ISA, you will lose the tax-free status on those funds.

This also means the money you pay into the new ISA will count towards your current year’s allowance, which may not be what you intended.

How to fix it:

• Always initiate an ISA transfer: When moving money between ISAs, tell the new ISA provider you want to transfer an existing ISA. They will handle the process with your old provider.
• Check for transfer fees: Some providers charge a fee for transferring out. Check this beforehand.

4. Not reviewing your savings strategy regularly

Your financial goals and circumstances can change, and so too should your savings strategy.

Sticking to the same old approach might mean you’re missing out on better rates or more suitable investment opportunities.

How to fix it:

• Schedule regular reviews: Set a reminder to review your savings and investment accounts. Do this at least once a year. Ideally, around the end of the tax year (March/April).
• Reassess your goals and risk tolerance: Ask yourself if your current accounts still match where you want to be financially.

By being aware of these common mistakes and taking proactive steps to avoid them, you can ensure your savings strategy remains effective and tax-efficient.

Next steps

You’ve got a handle on the basics of what to do when your Cash ISA is full. Now, let’s look at how you can further optimise your financial planning.

Consider a diversified investment portfolio

If you’ve started with a stocks and shares ISA or a General Investment Account, the next step is to build a well-diversified portfolio.

This means spreading your investments across various asset classes (like stocks and bonds), different industries, and geographical regions.

Diversification helps to reduce risk, as a downturn in one area might be offset by gains in another.

• Example: Don’t just invest in UK companies. Consider global funds that expose you to the US, Europe, and emerging markets. Don’t put all your money into tech stocks. Also look at healthcare, consumer goods, or utilities.

Explore passive investing with ETFs or index funds

For many everyday investors, passive investing is a highly effective strategy.

This involves investing in exchange-traded funds (ETFs) or index funds that track a specific market index, like the FTSE 100 or the S&P 500.

These funds aim to replicate the performance of the index, rather than trying to beat it.

They typically have lower fees than actively managed funds, which can make a significant difference to your returns over the long term.

• Example: A Vanguard S&P 500 UCITS ETF aims to track the 500 largest US companies. Investing in such a fund gives you broad exposure to the US stock market with one investment.

Pensions as a long-term savings vehicle

While not an ISA, contributing to a pension is another excellent way to save tax-efficiently for the long term.

You typically get tax relief on your contributions, meaning the government effectively tops up your pension savings.

For example, a basic rate taxpayer gets 20% tax relief, so for every £80 you pay in, £100 goes into your pension pot.

Higher and additional rate taxpayers can claim even more.

The money in a pension grows free from UK income and capital gains tax, similar to an ISA.

However, you generally can’t access your pension funds until a certain age (currently 55, rising to 57 from 2028).

• Why it’s advanced: Pension contribution rules can be complex. For most, the annual allowance is £60,000. Deciding how much to contribute needs careful financial planning.

Consider seeking professional financial advice

As your financial situation becomes more complex, or if you have specific long-term goals (like retirement planning or estate planning), consulting a qualified financial advisor can be incredibly beneficial.

They can help you:

• Create a holistic financial plan: They look at all your assets, debts, and goals. They build a comprehensive strategy.
• Optimise your tax position: They help you navigate CGT, income tax, and inheritance tax efficiently.
• Choose suitable investments: They give personalised recommendations. These are based on your risk tolerance and goals.
• Plan for major life events: Such as retirement, buying a second home, or passing on wealth.

How to find an advisor:

• Unbiased.co.uk: A good place to start. Find regulated financial advisors in the UK here.
• Personal recommendations: Ask friends or family for suggestions.
• Check their qualifications and regulation: Make sure they are regulated by the Financial Conduct Authority (FCA). Also, check they have relevant qualifications.

Frequently Asked Questions

Can I have more than one Cash ISA?

Yes, you can. However, you can only put new money into one cash ISA in any single tax year. You can have multiple cash ISAs opened in previous tax years. You can also transfer money between them. The key rule is your total new contributions across all ISA types in a single tax year cannot exceed the overall £20,000 allowance.

How does transferring an ISA work?

To transfer an ISA, you must tell your new ISA provider to arrange the transfer. This applies whether it’s from a cash ISA to another cash ISA, or to a stocks and shares ISA.

Do not withdraw the money yourself and pay it into the new ISA. This will make you lose its tax-free status. It will also use up your current year’s ISA allowance unnecessarily. Your new provider will contact your old provider. They will handle the transfer, preserving the tax-free wrapper.

Is it better to invest in a Stocks and Shares ISA or a General Investment Account?

Always prioritise a stocks and shares ISA if you have allowance left. It’s better than a General Investment Account (GIA). The stocks and shares ISA offers a tax-free wrapper. This means all capital gains and income from investments are free from UK tax.

A GIA is subject to Capital Gains Tax and income tax on dividends or interest. This applies once your personal allowances are used. A GIA is usually used after you’ve fully used your annual ISA allowance.

What is the Personal Savings Allowance (PSA)?

The Personal Savings Allowance is the amount of interest you can earn on savings each tax year without paying tax. For basic rate taxpayers, it’s £1,000. For higher rate taxpayers, it’s £500.

Additional rate taxpayers have no PSA. Any interest above your PSA is taxed at your marginal income tax rate. This allowance applies to interest from all non-ISA savings accounts. This includes regular savings accounts, fixed-term bonds, and bank current accounts.

What are the risks of investing in a Stocks and Shares ISA?

The main risk with a stocks and shares ISA is that investment values can go down and you could get back less money than you put in. Investment performance depends on market conditions. It also depends on the companies you invest in and other economic factors.

This risk is higher for short-term investments. That’s why it’s best to invest for at least five years, or longer. This helps you ride out market fluctuations. Diversification can help manage this risk.
