Why the tax year matters
Making the most of your tax-free annual allowances will help give you the best chance of investment success.
And investing at the start of the tax year can turbocharge your returns over time.
It’s all thanks to the power of compounding. This is when you earn returns on your returns, as well as on the money you invest. This can help your investments grow more quickly over time.
You have until 11.59pm on 5 April 2027 to make tax-efficient investments this tax year.

Why it's smarter to invest than save
Long-term returns
Investing can be a powerful way to build wealth over time. In the long term, shares deliver higher returns than saving cash.
How your wealth grows
Compounding is when you earn returns on the money you invest as well as on the returns themselves. It can have a big impact on your wealth.
