How to invest in your 40s

It’s common for people to hit their stride professionally when they’re in their 40s. People in their 40s may also want to think about planning for significant life events, such as children’s education costs or retirement at 55 or 60

But juggling the costs of childcare, mortgage repayments, home renovations, and your pension contributions means that any extra cash needs to be handled with care.  

Are you keen to start investing but wondering where to start? We’ll share some valuable tips to help you make sound investment decisions in your 40s that will successfully grow your money. 

1. Identify your investment goals 

Knowing what you want to achieve financially can help you decide how to invest any spare cash. 

You might want to overpay on your mortgage, put aside some savings for your child or give your pension pot a boost. 

Once you’ve identified your short and long-term financial goals, consider the following questions: 

• Do you need easy access to your funds? 

• How soon would you like to see a return on your investment? 

• How much risk are you comfortable with? 

If you’re happy to play the long game and expose yourself to some risk, you could consider investing in the stock market. 

You could also consider a flexible ISA or a savings account if you’re looking to boost your savings, although the returns are likely to be lower than the stock market. 

While you currently have a £20,000 ISA allowance, be aware that from April 2027, if you are under 65, the amount you can hold in a Cash ISA will be capped at £12,000. The remaining £8,000 must be used for Stocks & Shares or other ISA types to remain tax-free.

Before you make any more decisions, it’s time to review your retirement pot. 

2. How to review and maximise your pension in your 40s

Is your pension in the best possible shape? 

Before you consider investing in the stock market, make sure you’re happy with your pension pot. 

Retirement might still seem like a long way off, but making regular pension contributions is one of the most efficient ways of maximising your money in the long term.

A healthy pension also gives you financial security and peace of mind in the future.  

If you’re employed, you’ll likely already have a workplace pension (or more than one). Check to see if you can increase your contributions and whether your employer will match any increases. 

If you’re self-employed, setting up a Self-Invested Personal Pension (SIPP) can help you take advantage of tax relief on your retirement savings.  

You can also set up a SIPP alongside your workplace pension. A SIPP has all the tax relief benefits of a workplace pension and gives you control over how your pension is invested. 

The money purchase annual allowance (MPAA) limits the amount you can contribute to your pensions if you've started accessing them.

For 2026/27, the MPAA is £10,000. This is crucial for those who have already begun drawing from their pension and want to continue contributing.

There are annual contribution limits across all pensions combined (including SIPPs and workplace pensions). For the 2026/27 tax year, the annual allowance is £60,000, and exceeding this can lead to significant tax charges, so it is vital to track all contributions across workplace and personal schemes.

The Lifetime Allowance (LTA), which limited the amount you could save overall in a pension and receive tax relief, was abolished in April 2024, but further changes could occur, so this should be kept in mind.

3. How to invest in stocks and shares in your 40s 

Thinking about investing in stocks and shares?

Whether you’re new to investing or have been doing it for a while, diversification is the key to success by helping to minimise your exposure to risk and maximise your potential returns. 

Diversification means spreading your investments across different asset classes, such as stocks, bonds, property, and mutual funds. 

You can also buy shares in different types of companies and various regions around the world.

With a diversified portfolio, low-performing investments can be balanced out by ones that are doing well. 

You should aim to hold these investments inside a Stocks & Shares ISA wrapper. This protects capital gains and dividends from HMRC. With the Capital Gains Tax (CGT) allowance remaining at a low £3,000 for 2026/27 and Dividend Tax rates increasing by 2% from April 2026 (to 10.75% for basic rate and 35.75% for higher rate), holding shares outside this wrapper is increasingly tax-inefficient.

Gains and income inside an ISA are tax-free but there are no further tax reliefs on ISA contributions, unlike pensions.

4. Should you invest in a fund in your 40s?

If you’re new to investing, you might prefer to buy an actively managed fund, which means a professional fund manager selects your investments for you. 

You should review your portfolio regularly with a qualified financial adviser to make sure your investments are still meeting your goals. 

5. Are hedge funds a good investment for high net worth individuals in their 40s?

For high net worth (HNW) individuals, hedge funds can offer high financial returns, but they can be higher risk. 

Hedge fund managers tend to use more aggressive investment strategies to get higher returns and may invest in non-traditional assets such as property and foreign currency. 

To invest in a hedge fund, you need to be an accredited investor, so you need to have an annual income of at least £200,000 or a net worth of £1 million, excluding property. 

For those with an annual income of at least £200,000 or a net worth of £1million excluding property and you’re prepared to adopt a high-risk strategy in the hope of high returns, a hedge fund is a viable option. 

How can I ensure I invest effectively in my 40s? 

A successful investment strategy in your 40s will be determined by your unique circumstances and financial goals.  

Your first step should be to pay off any debt and make sure you’ve got a financial buffer in place for emergencies. Having 3-6 months' worth of expenses saved is a common recommendation.

Low-interest debt might not need to be paid off immediately if inflation is higher than the interest rate, as the real cost of the debt will decrease over time

Next, look at your pension and make sure you’re happy with your contributions in order to achieve lasting financial security.

Inheritance Tax planning

People in their 40s may also start thinking about inheritance tax (IHT) planning. This is more important than ever due to major changes brought in by the current government.

From April 2027: unused pension funds will no longer be exempt from Inheritance Tax. They will be included in the total value of your estate. This fundamentally changes the strategy for those in their 40s who were planning to use their pension as a primary tax-free vehicle for passing on wealth.

Investments in certain assets like Alternative Investment Market (AIM) shares used to be IHT-exempt after two years. As of April 6, 2026, IHT relief on AIM shares was cut from 100% to 50%, meaning these stocks are now effectively taxed at 20% upon death. 

Additionally, a new £2.5 million cap now applies to 100% Agricultural and Business Property Relief. Given these tightening rules, structured professional advice is now a necessity for larger estates.

Get expert financial and investment advice

Investing in your 40s can carry a range of notable benefits, especially if you invest in a structured way.

Many people in their 40s are at the peaks of their careers and earning potential, which means that they have extra cash available to invest in growing their pension funds, diversifying their investment portfolios, and investing in stocks, shares, funds, and even hedge funds to grow their cash.

Whenever you decide to invest, it’s worth getting advice from a financial adviser. 

Unbiased can match you with an expert financial adviser near you who can help you develop a solid investment strategy that’s tailored to your unique circumstances.
