What is Tax Year End?
The UK tax year always begins on the 6 April and ends on 5 April the following year. So the end date of the current tax year is 5 April 2025.
The current tax year we are in is tax year 2024/2025. This is because the tax year began in 2024, and ends in 2025.
If you still need to know more of the basics around tax, read our guide on tax rates and allowances.
Why does Tax Year End matter?
Tax Year End matters because it’s usually the last opportunity you have to use your annual ISA allowance, currently £20,000, and your annual pension allowance, currently £60,000. Not only that, but any newly announced financial rules usually take effect in the new tax year.
On 6 April 2024, the Capital Gains Tax (CGT) exemption was reduced from £6,000 to £3,000.
How does the tax year work?
The UK tax year provides a framework for the assessment and collection of taxes. When a new tax year begins, your tax allowances reset. This includes allowances for income tax, capital gains tax, ISAs and SIPPs, and lots more.
Making the most of your ISA and SIPP allowances before the tax year end is a strategic financial move. Your ISA and SIPP savings can grow free from income tax and capital gains tax, and money paid into a SIPP also receives a free government top up from Tax Relief.
Take a look at tax year allowances you need to know about below.
What are the annual allowances?
| Tax year | 2024/25 |
| ISA subscription limit | £20,000 |
| Junior ISA (JISA) subscription limit | £9,000 |
| SIPP Annual Allowance limit | up to £60,000* |
| SIPP Money Purchase Annual Allowance (MPAA) | £10,000* |

Two important changes from April 2024

- The annual tax-free dividend allowance also halved from £1,000 to £500. Find out more.
Things to do before end of tax year
- Top up your ISA. To make use of the current tax year allowance, make sure you’ve topped up your ISA and added cash before the tax year ends – even if you’ve not decided how to invest it. So long as you have contributed before your £20,000 allowance refreshes.
- Build a nest egg. If you’ve got children, you can also open a Junior ISA and begin saving for when they turn 18. This can help with those big expenses they might face in early life – like university, or their first car.
- Make pension contributions. Tax Year End is a good time to reassess your pension and make any last minute contributions. Unlike ISAs, you can roll over any unused allowance from the past three years and claim tax relief. Check if you have unused years before you lose them.
- Use your CGT allowance. Capital Gains Tax rules are changing. Once the new tax year starts your capital gains allowance will reduce from £6,000 to £3,000 and it can’t be rolled over. So, if you’ve been planning a sale, consider selling before the tax year ends to make the most of your allowance before it shrinks.
- Get dividend savvy. If you invest outside of a SIPP or ISA, such as a Trading Account, your personal dividend allowance is also reducing in the new tax year from £1,000 to £500. Before making any new investments in your Trading Account, consider making them in your ISA where you have an uncapped ISA dividend benefit.

Expert tip
This year's adult ISA allowance is £20,000 – so if you have cash to spare and unused allowance, or shares in a Trading Account, now is the time to make your money work harder. The more you pay in now, the more time your money has to grow. With ii, you only pay a low monthly flat fee for your entire subscription and not for each account.
Customer reviews
My husband has been holding Trading and SIPP accounts with ii for over a year and is happy with it so I have just opened my ISA account too. I like its fixed subscription fees.
Their flat rate fees save me an amazing amount of money for my large portfolios and really glad I moved to them. I self-invest using their comprehensive investment research information which is easy to understand, and their best picks and ready portfolios are really good to read and consider.
