The power of ISA investing

Time is the most powerful force in investing. Consider this scenario: an investor puts £10,000 into a Stocks & Shares ISA and adds £500 per month, earning an average of 7% per year.

20-year projection (illustrative)

Total invested: £130,000
Estimated value: £282,400
Tax saved vs. non-ISA: Approx. £27,000

This is for illustrative purposes only and assumes consistent growth. Actual returns will vary. However, the point is clear: the tax protection of an ISA compounds just as powerfully as investment returns over time.

Investment growth over time

Junior ISA — invest in your child's future

A Junior ISA (JISA) is one of the most tax-efficient ways to save for a child. Parents or guardians can open the account, but anyone can contribute — ideal for grandparents, godparents and other family members.

The money belongs to the child and cannot be withdrawn until they turn 18, when the account automatically converts to an adult ISA. This long time horizon makes it particularly powerful — even small regular contributions can grow substantially.

  • Open for any UK child under 18
  • Anyone can contribute, up to the annual limit
  • Choose cash, stocks & shares, or a mix
  • Converts to adult ISA at age 18 automatically

Frequently asked questions

Can I have more than one ISA?

Yes, you can hold multiple ISAs — but you can only open and pay into one of each type per tax year. For example, you could pay into one Cash ISA and one Stocks & Shares ISA in the same year, as long as your combined contributions don't exceed £20,000.

What happens if I don't use my full ISA allowance?

ISA allowances cannot be carried forward — any unused allowance is lost at the end of the tax year (5 April). This is why it's worth planning your ISA contributions early each year to make the most of your tax-free allowance.

Can I transfer an existing ISA to MG Capital?

Yes. You can transfer ISAs from other providers to MG Capital without losing the tax-free status of the money. Cash ISAs can be transferred to either a new Cash ISA or a Stocks & Shares ISA. The transfer process typically takes 15–30 business days.

Are ISAs included in my estate for Inheritance Tax?

Yes, unlike pensions, ISAs are included in your estate for Inheritance Tax purposes. However, if you leave your ISA to a spouse or civil partner, they benefit from an Additional Permitted Subscription (APS) — they can invest an amount equivalent to your ISA into their own ISA, preserving the tax wrapper.
