Why save into an ISA?
Using an ISA means you can earn interest on your savings without paying tax on any interest or capital gains – a win-win solution. Unfortunately in recent years, low-interest rates coupled with high inflation make it near impossible to get a good return.
Why use an ISA?
The benefit of an ISA is the tax-free wrapper you will earn on any interest, dividends, or capital gains from your investments, no matter how much you earn. The downside to an ISA is you can only invest up to the maximum annual ISA allowance, which for the 2022/23 financial year is £20,000.
In the 2019/20 tax year, HMRC reported roughly 13 million Adult ISA accounts were subscribed. During that period, HMRC also reported a staggering £75 billion being invested into the ISAs.

Do ISAs give the best rate?
Not all ISAs pay the best interest rate. All banks and building societies advertise the ISAs using gross interest rates and this can help you compare ISA accounts on a like-for-like basis. In times of low-interest rates, the amount of interest you will be gaining (which is linked to the Bank of England’s base rate) means you may end up losing money by keeping it in an ISA.
Are ISAs safe?
Every bank or building society has to be approved by the HMRC and the Financial Conduct Authority (FCA) in order to manage and promote its financial services.
You can usually find this information at the bottom of the provider’s website. However, you should be aware there are some websites which promote an ISA product while not certified by the FCA. To view whether a bank or building society is safe for you to invest in, you should take a moment to look at the FCA Registry and the Government’s list of approved Savings Account (ISA) Managers.
In addition, you could also find out if a provider is registered with the Information Commissioners Office (ICO), which upholds the regulation of data protection in the UK.
Which ISAs give you the best rate of return?
Each ISA has its benefits and drawbacks, but there are different from each other so you can diversify your investment to minimise the risk and maximise the potential rate of return.
Historically, the ISA with the best base rate of return is the Lifetime ISA. However, with the limitation imposed on the LISA, the current best route is either the Stocks & Shares ISA or the Innovative Finance ISA.

Are ISAs worth the investment?
Innovative Finance ISA, also known as IFISA or P2P ISA, utilises the peer-to-peer lending network. By investing your allowance in an IFISA, you can cut out the middleman (i.e. the bank) and in return gain a higher percentage of the interest rate.
P2P lending has become very popular in recent years as a way for savers to earn more interest compared to alternative ISA or lending accounts. Various platforms offer investors and lenders the ability to put their money as loans to small businesses or individuals, earning a rate of interest over time as their money is paid back*
Broadly speaking, P2P loans are considered high-risk investments. However, the higher the risk, the higher the potential returns. Typical rates across the board are between 4-10% but usually, your money will be tied to that IFISA long-term. Usually, you can withdraw funds as long as they are not being used by the platform, but you may have a waiting period to receive them back.
