A Flexible ISA allows you to withdraw and replace money within the same tax year without affecting your annual ISA allowance.
This feature gives you more freedom to manage your investments - whether you need to access your money temporarily or simply want to move funds around.
InvestEngine’s Stocks & Shares ISA is fully flexible.
How it works
Here’s a simple example:
- You invest £10,000 into your ISA
- Later, you withdraw £2,000
- You now have the option to replace that £2,000 within the same tax year - without using up more of your £20,000 allowance
- So in that tax year, you could invest up to £20,000 total, regardless of the temporary withdrawal.
Flexible ISA rules are set by HMRC. See official guidance for more detail.
What to keep in mind
- Replacements must happen in the same tax year
- The flexibility only applies once you’ve made a withdrawal
- It does not increase your allowance - it simply lets you reclaim space you’ve already used
- The flexibility only applies to your Stocks & Shares ISA
How does it work with InvestEngine?
If you withdraw from your InvestEngine ISA, your available ISA allowance is updated in your account dashboard. You’ll see how much can still be replaced this tax year.
When you add funds back, they’ll be treated as replacements first, before using any remaining allowance.
