A guide on the advantages of ISAs

Take me to the Signia ISA

ISA allowance: ISA limits & rules

An Individual Savings Account or ISA is a tax-efficient way to save for the future. Each year the government sets an annual allowance which is the maximum you can put into an ISA in any given year. This year you can invest your £20,000 allowance into a Stocks & Shares ISA and any gains you make will be free from tax.



This tax year (2020/21) you can invest up to £20,000 in ISAs.


Any returns from your ISA investment are tax-free* and to ensure simplicity there is no need to declare ISAs on your tax return.


There are 4 main ISAs available on the market, these are Cash ISAs, Stocks & Shares ISAs, Lifetime ISAs and Innovative Finance ISAs. You can subscribe to one each, per tax year, providing you don't exceed the annual allowance.

Don't lose your allowance

At the beginning of each new tax year your annual ISA allowance resets. You cannot carry your allowance over between years, so if you don’t use it you lose it.

Transfer your ISA

You can transfer unlimited amounts from current ISAs to the Signia ISA making them easier to manage, reducing fees and giving them a better chance to grow.

The Signia ISA

You can open a stocks and shares ISA with Signia Invest, provided you haven't opened the same kind of ISA elsewhere this tax year.

What is an ISA?

An ISA or an Individual Savings Account provides investors or savers a way to receive any returns on investments held in their ISA tax-free*. There are 4 main ISAs on the market that are available, you can subscribe to 1 each per tax year providing you are within the annual allowance which is currently £20,000.

The Signia Invest ISA is a stocks and shares ISA. Tax treatment does depend on the individual circumstances however any returns held within your Signia Invest ISA, are free from income and capital gains.

The different ISAs in more detail:

Cash ISA
A cash ISA works in the same way as cash savings account and are ultra-low risk. As a result, any interest rates paid on cash in an ISA are typically very low and closely linked to the Bank Of England (BOE) Interest Rate and the Consumer Price Index (CPI).
Stocks and Shares ISA
A Stocks and Shares ISA allows you to hold investments traded on the stock market. You will usually pay a fee or a commission depending on the route you take, and the interest will fluctuate due to a number of factors including the nature of the underlying investments held in the account.
Innovative Finance ISA
The UK Government introduced the innovative finance ISA on 6th April 2016. The IFISA was born from the credit crisis in 2008 which led to an increased demand from UK businesses for short to medium term credit facilities, which the banks are unable to meet.
Lifetime ISA
The lifetime ISA is used to buy your first home or to save for later life. You must be under 40 to open a Lifetime ISA. The contribution is capped where you can put in up to £4,000 each year, until you’re 50. The government will add a 25% bonus to your savings or up to a maximum of £1,000 per year.

How much can I invest in an ISA

Each tax year, individuals have an allowance that can be paid into ISA accounts, for the current tax year (2020/21) the allowance is £20,000 (for ISA accounts and £9,000 for JISAs).

This can be invested into one ISA or split between the different ISA types.

Crucially, any unused allowance doesn’t roll over – so if you don’t use it, you lose it – forever.

Any savings or investments which stay within the tax-free ISA wrapper will continue to earn interest and benefit from the tax benefits until you withdraw the money. This means it’s possible to have considerable amounts held within an ISA, as some people will take advantage of the maximum allowance each tax year.

Transfers – Any money already in an ISA wrapper can be transferred and will not impact the annual allowance or tax-free status.

Who can open an ISA?

You need to be a UK resident aged 16 or over to open a cash ISA, or aged 18 or over to open a stocks & shares ISA or innovative finance ISA. You can’t open an account with someone else, or on behalf of someone else.

The Signia Invest ISA is a stocks and shares ISA, therefore anyone wanting to subscribe has to be a UK resident aged 18 or over.

  • Any returns earned on any investments held in an ISA will be received gross and will not be subject to capital gains or income tax
