Individual Savings Accounts (ISAs) are long-term savings accounts issued to UK residents by banks, credit unions, building societies, and other financial institutions. The best element about ISAs is that you get a tax-free savings account, meaning you will not pay capital gains or income tax on any gains from your ISA. 

If you are considering opening an ISA account, we take you through the best ISAs to consider in the UK. In the end, you should be able to figure out which ISA is best for you and whether signing up for one is worth it.

To ensure we are on the same page, let’s take a quick overview of ISA types in the UK. Remember, all ISAs are tax-free, and you get to save up to £20,000. Here are the four types of ISAs to note.

1. Cash ISAs

Cash ISAs are available for UK residents aged at least 16 years. With this account, you can save up to £20,000 and earn tax-free interest. Simply put, Cash ISA members are given an annual ISA allowance every tax year that sets the maximum amount (£20,000) to be paid tax-free. As a Cash ISA member, it is crucial to make full use of this allowance failure to which all will be lost and cannot be carried over to the next tax year. 

Note that Cash ISAs come in different types, including easy access, fixed rate, and notice. Each type of Cash ISA has its own benefits, so ensure you confirm the best for your needs. In addition, you can only have one active Cash ISA annually to benefit from the tax-free allowance that comes with owning this account. 

2. Stocks and Shares ISAs

Also known as investment or share dealings ISAs, stocks and shares ISAs are accounts tailored to protect your investment from owing taxes. This means that your money is used to invest in various assets, and you get to keep all the capital gains and income, like dividends and interest, without paying taxes. Some of the assets to invest using your money in stocks and shares ISAs include commodities, bonds, ETFs, shares, and properties. 

To sign up for the stocks and shares ISA, you must be at least 18 years and be a UK resident. Like investing using stock brokers, there is no guarantee for profits since the financial market is unpredictable. However, investing in various assets using this account can earn you more profits than cash savings. Remember, there are investment fees and commissions to incur, so choose a provider you can afford. 

3. Innovative Finance ISAs

With an Innovative Finance ISA, you become a lender whereby you provide loans to approved individuals and businesses. The lending is done via an online peer-to-peer platform for a fixed tax-free interest within a set period. 

Remember, always consider having a financial institution, such as banks acting as middlemen. For your own interest, you must gauge your risk appetite by ensuring your money is protected by the Financial Services Compensation Scheme (FSCS). This way, it will be easier for you to make a claim for compensation on defaulters. 

4. Lifetime ISAs

Lifetime ISAs are more flexible and give you an opportunity to focus on saving for the future. With this tax-free savings account, you can save to purchase your first home or retire with enough money. Note that this Lifetime ISA (LISA) is ideal for UK residents aged between 18-39 years. The best element about LISA is that you get to earn a 25% bonus on any amount you save. This means that for every £4 you save, you earn £1. You can only save £4,000 in each tax year. 

With LISA, it is up to you to decide whether you want to hold cash, invest in a house or combine both. The home to purchase must cost at most £450,000, and you must hold your account for at least 12 months before making your first deposit for the mortgage.
