FAQs: Everything you need to know about the Stocks and Shares ISA allowance

When does the ISA allowance renew?

The tax year, set by HM Revenue & Customs, ends at midnight on 5th April each year. This means that you get a new ISA allowance starting on the 6th April each year. 

If you are looking to maximise the use of your ISA allowance this financial year, then it is important to remember that the deadline to do so is the 5th April 2025 as allowances do not rollover if you haven’t used it all.

 Does the ISA allowance roll over if I don’t use it?

No, it doesn’t. Each year your ISA allowance is renewed. If you don’t use your full ISA limit before the end of the tax year (which is at midnight on 5th April) then your ISA allowance for the current tax year has gone and can no longer be used. It’s not possible to roll over any unused allowance. For example, if you save £10,000 into your ISA this tax year, you can’t add £30,000 into your ISA next year within the tax-free limit. Your ISA allowance would remain at £20,000 (unless the Government changed the ISA limit amount).

If I transfer my ISA does it affect my annual allowance?

Transferring your ISA from one ISA provider to another does not affect your annual allowance. You still can save up to the annual limit of £20,000 for this financial year.

You’re free to transfer and split your ISA allowance any way you like across a Stocks and Shares ISA, Cash ISA, Lifetime ISA (maximum of £4,000) and an Innovative Finance ISA, as long as you stay within the overall limit.

However, there are a couple of stocks and shares isa transfer rules that you need to be aware of. Be careful when transferring a stocks and shares or cash ISA into a Lifetime ISA. While this won’t affect your overall annual ISA subscription allowance for that tax year, it will count towards your annual Lifetime ISA subscription limit of £4,000.

This also applies to if you are transferring your savings from a previous tax year. This won’t count towards your allowance for the current year. Be sure to ask your ISA provider to help you with the transfer to avoid going over your current tax year allowance.

What happens if I go over my Stocks and Shares ISA limit?

It’s important you are aware of the ISA allowance each tax year to avoid exceeding the annual limit. For the 2024/25 tax year the Stocks and Shares ISA limit is £20,000.

If you do exceed your ISA limit, the best thing to do is contact HMRC by calling their helpline on 0300 200 3300 and explaining your situation. They will help you work out which payment breached the limit and reclaim the money for you. There may be a charge for any tax due. If you don’t let them know, HMRC will get in touch to let you know how to correct your mistake at the end of the tax year.
