Pay no tax when you save with a cash ISA

Whatever you’re saving for, we have a varied range of tax-free accounts to suit savers with different goals.

There's a tax-free savings account to suit you

You can invest in four separate ISAs each year: a cash ISA (from age 16), a Stocks & Shares ISA (from aged 18), Innovative Finance ISA (from aged 18) and a Lifetime ISA (from aged 18). A Lifetime ISA can only be opened between the ages of 18 and 40 and once opened you can invest into the account up to age 50. You can invest in any combination of the four types of ISA in one tax year up to your total annual ISA allowance limit which is £20,000 for the 2019/20 tax year, however the annual contribution limit into a Lifetime ISA is £4,000. 

By choosing a Cash ISA you will benefit from tax-free interest. Although Stocks & Shares ISAs are tax efficient they are not completely tax-free. These ISAs are best suited for money that you can leave untouched for at least 5 years or more.

An Innovative Finance ISA allows interest and gains from peer to peer loans to qualify for tax advantages.

A Lifetime ISA can be used to save for a deposit for your first home or your retirement (where you could be eligible to receive a bonus based on your savings).

Chelsea Building Society only offers Cash ISAs.
