What are the ISA values for 2019/20?

Spring into ISA season

ISAs (Individual Savings Accounts) are a tax-efficient way of saving. However, last year the number of adult ISA accounts subscribed to fell from 11.1 million in 2016/17 to 10.8 million in 2017/18.

However, there’s positive news for children’s savings, with around 907,000 junior ISAs subscribed to in 2017/18, which represents a sizeable increase on the previous year.

If you’re ready to get going with an ISA for the first time this year, or have fresh motivation for your 2019/20 savings plans, how much will you be able to save this savings year?

2019-20 ISA allowances

In 2019-20 the annual ISA allowances for adult ISAs are not increasing. 

The total amount you may invest in an ISA for yourself is £20,000. This is the same as the last tax year. If you have two or more different ISAs, your total contribution must not exceed £20,000.

However, junior ISAs have different limits, and they are rising this next tax year to £4,368 from £4,260 in 2018/19. 

Spring into ISA season

You are not permitted to ‘carry over’ unused allowance from one year to the next. You must use it or lose it! You are, however, able to choose to split your allowance across different types of ISA. Alternatively, you may want to use your full allowance on one ISA.

Junior ISA limits

While adult ISA allowances have been frozen for 2019-20, Junior ISA limits have been increased in line with inflation to £4,368, from £4,260.

You can open the Newbury Building Society Cash Junior ISA with as little as £50. Full terms for the account are available here
