Investing wisely isn’t just about choosing the right assets; it’s also about minimising how much tax you pay.
Here are five ways to pay less tax on your investments.
1. Make the most of your ISA allowance
One of the simplest ways to shield your investments from tax is to make the most of your individual savings account (ISA) allowance. You can invest up to £20,000 in ISAs in the 2025-26 tax year. Your money can grow free from the income tax you might pay on the dividends1 or interest you receive, as well as the capital gains tax (CGT) that could be applied on any profits (‘gains’) you make when selling investments.
The earlier you invest, the better. Why not consider increasing how much you’re investing each month or adding any lump sums to your ISA? It could make a big difference to the size of your pot over the long term.
2. Increase your pension contributions
If you’re able to lock away your money until age 55 (or 57 from April 2028), saving more money in pensions offers significant tax benefits.
When you make a personal pension contribution, you get tax relief from the government. For every £80 you contribute, you get a top-up of £20. If you’re a higher-rate or additional-rate taxpayer, you can claim back an additional £20 or £25, respectively, via your self-assessment tax return.
Most people can get tax relief on contributions of up to 100% of gross relevant earnings, capped at £60,0002. In some circumstances, you might be able to make pension contributions over your annual allowance and still benefit from tax relief. This is because you can ‘carry forward’ unused allowances from the previous three tax years. Read more about carry forward rules.
If you’re a non-earner, you can contribute up to £3,600 per year (including tax relief), but this can’t be carried forward to future tax years.
Your investments are also sheltered from CGT within a pension, enabling them to grow tax-free over the long term.
3. Manage capital gains tax on non-ISA investments
If you can’t make more use of your ISA or pension allowances, it’s still possible to manage CGT on investments you hold outside these tax wrappers. In the 2025-26 tax year, you can realise up to £3,000 of profits on your investments without incurring a CGT bill. You can’t carry forward any part of your CGT allowance into subsequent tax years, but you can carry forward losses. Learn more about how to reduce your CGT bill.
4. Keep an eye on your personal savings allowance
The personal savings allowance is the amount of interest you can earn on savings each year without paying tax. Currently, it’s set at £1,000 for basic-rate taxpayers and £500 for higher-rate taxpayers. It’s £0 for additional-rate taxpayers. If you’re at risk of exceeding the limit, you may want to consider other ways to save and invest your money.
Holding some money in cash savings is important because it can help you cover unexpected emergencies without having to resort to short-term, high-cost debt (such as using a credit card with high fees or entering an unplanned overdraft). For one-off expenses, one rule of thumb is to keep the greater of £2,000 or half a month’s expenses in a bank account. When it comes to an income shock, we generally suggest keeping back 3-6 months’ expenses in an accessible account.
For savings over and above your emergency fund, a stocks and shares ISA can give your money more opportunity to grow over the long term. Shares have historically offered higher returns than cash over the long term and have outpaced inflation3 by a greater margin. Although investments go down as well as up and you may get back less than you invested, history shows that patient investors tend to be rewarded for this extra risk.
5. Use your spouse’s allowances
If you’re married or in a civil partnership, it can be more tax efficient to organise your finances as a couple than go it alone. This is because you can take advantage of each other’s tax allowances. As a couple, you essentially have two ISA allowances, two pension annual allowances, two CGT allowances and two personal savings allowances.
Spouses and civil partners can transfer assets to one another without paying tax. This might come in handy if one partner is a higher-rate taxpayer and the other is a basic-rate taxpayer. By transferring certain assets into the basic-rate taxpayer’s name, you could benefit from a lower rate of tax, or pay no tax at all, on income and capital gains.
Tax is complicated, so we’d suggest speaking to a financial adviser if you’re unsure what’s right for you. However, it’s always worth remembering that the less tax you pay on your investments, the more money you’ll be able to put towards your future.

2 For more on what counts as ‘relevant earnings’ that can earn tax relief when used to fund a pension, see the HMRC Pensions Tax Manual. Your annual allowance might be lower than £60,000 if you have a high income or you’ve already flexibly accessed your pension pot. To work out if you have a reduced (tapered) annual allowance, see HMRC’s website.
3 Inflation is the rate of increase in prices for goods and services.
