Shares Isas: protect your assets from the taxman

Escape capital-gains and dividend taxes on investments ranging from stocks to corporate bonds with a shares Isa. Here’s how to find one that suits you.


With careful research you can find an Isa that's just right

If you haven't used up your 2018-2019 Isa allowance (£20,000) yet, and had planned on making some investments in the near future, you should doso with a stocks and shares Isa before the end of the tax year. As with a cash Isa, this is an account thatacts as a wrapper around your investments, allowing them to grow free of tax on capital growth or income.

Note that if you have money in another Isa, such as a cash or innovative finance Isa, this will come out of your total £20,000 allowance. So if you have £5,000 in a cash Isa, you can only put £15,000 into your stocks and shares Isa.

Although an investment Isa is generally referred to as a stocks and shares Isa, that label is somewhat misleading. In addition to shares listed on major stock exchanges around the world, you can hold investment trusts; unit trusts and open-ended investment companies (Oeics); exchange-traded funds (ETFs); and corporate and government bonds in your Isa.

The fees to consider

You will also be charged for buying and selling investments, so make sure you take those charges into account, too. However, as we've learned in recent surveys asking about the factors that are most important to MoneyWeek readers when they are picking an investment platform, cheap fees on their own aren't enough. Reliable and accessible customer service is also important, as is the availability of awide range of investments. See below forsome recommendations of brokers suitable forvarying circumstances.

Keep in mind that if you want to transfer money from a cash Isa to a stocks and shares Isa you can do so without affecting your annual allowance, but make sure you do it through the formal transfer process (see page 32). You can't just transfer investments held outside an Isa wrapper into a stocks and shares Isa. To do this, you'll have to sell your investments, and then buy them back within the wrapper.

Some brokers will reduce trading fees if you transfer an investment into a regular dealing account on their platform, then sell it to buy back via an Isa. In this situation you need to take into account capital-gains tax. If you are set to breach your allowance (£11,700 for this year, £12,000 for 2019-2020), consider splitting the sales over two tax years, or transferring an investment to a spouse that hasn'tyet used up their own CGT allowance, sothat they can sell it and then buyit back within an Isa.

Note that passive investment giant Vanguard also now runs its own platform Vanguard Investor which allows you tohold Vanguard funds very cheaply. Clearlythis is only appropriate if you are looking to hold their funds. As you might expect, given the company's reputation for being such a low-cost provider, the platform charges at Vanguard are low: there is an annual fee of 0.15% on investments up to £250,000, which is less than half the industry average, as the finance blog Money to the Masses points out. Above £250,000, there is no fee. This means there is a maximum platform fee of £375.

Interestingly, however, it may ultimately be cheaper to buy Vanguard funds through Interactive Investor (or "ii"), says Money to the Masses: ii is the largest platform to operate a fixed-fee model, and charges £22.50 every quarter, or £90 a year, regardless of your portfolio size. Because the underlying fund charge for investing in Vanguard funds is identical onboth platforms, this means that if you invest more than £60,000 in Vanguard funds, then you would be better off doing this via ii.
