Today a savvy investor can maximise their investments by using their £20,000  tax-free annual allowance with a Stock and Shares Individual Savings Account (ISA).

All capitals gains and interest income earned is free of income and  capital gains tax. If you fail to use all or part of your tax-free allowance you lose it. It doesn’t rollover to the next tax-year.

Bear in mind that investments can go up and down in value and you may not get back all of the amount you initially invested.

In each subsequent year of  investing you can keep adding to your ISA pot and see the benefits of compounding, meaning that as you add money in the following year, your capital gains and interest earned is subject to the compounding effect, which will see your returns multiply accordingly.

Selecting the right stocks and shares ISA for your circumstances, and the provider that suits you best, is not  straightforward in a competitive and crowded market of providers. In this guide, we provide you with an outline of all the ISA types but with a particular focus on the stocks and shares ISA. Plus we select this year’s best stock and shares ISA providers.

    How To Earn More From Stock and Shares ISA

    Have an investment plan

    Before you start investing, it is very important to have a plan. Take time to think about the options available, your aims and objectives with your investments as well as how long you plan to invest. You can fine-tune it and add strategies on how to handle and mitigate risks. It is important to review the plan frequently or every time you want to make investment changes.

    Diversify your Investment

    Most first-time investors are attracted to individual shares. However, because the stock market is highly volatile, this can be a risky endeavor. Investing in a collective vehicle such as  funds, has the advantage of a professional fund manager doing the stock-picking for you, or you could select a passive fund that, for example, tracks the value of an index such as the FTSE 100 or NASDAQ. Funds are useful for  building a diversified portfolio.

    Is it possible to have more than one ISA?

    Yes, you can hold all the types of ISA in the same tax year, but you cannot have more than one type of ISA in the same year. For instance, if you already have funded a stocks and shares ISA in this tax year, you cannot have another account of that type running concurrently. You can transfer accounts at any time.

    How much can I put into an ISA?

    Due to the numerous tax advantages of ISAs, the government limits the amount each account holder can contribute in each tax year. In the UK, the tax year runs from April 6 to April 5 of the next year. You can only put in £20,000 per tax year.

    Can I withdraw funds from ISAs whenever I want?

    You can withdraw from your stocks and shares ISA but those funds lose their tax-free status. If you want to transfer to another provider you must use the provider's transfer form to do so or you risk losing the tax-free status applied to the funds.

    Can I inherit an ISA?

    Nowadays, it is possible to inherit the ISA savings of your spouse or civil partner when they die and continue reaping the tax-free benefits. This is done by adding a one-off ISA allowance, which is equal to the deceased holdings. The additional permitted subscription will enable you to re-shelter the assets in your name without affecting your own ISA allowance of the same tax year.

    Is an ISA a safe way to hold my money?

    As long as the ISA provider is regulated by the Financial Conduct Authority (FCA), your funds are protected by the Financial Services Compensation Scheme (FSCS) up to the value of £85,000.
