For UK investors, using a stocks and shares ISA is a bit of a no-brainer. It allows you to invest up to £20,000 each year as you would normally, but any potential gains or dividends are shielded from the taxman. Any money you take out of your ISA won’t count as income either, so it’s a fantastic wealth-building tool.
Once you’ve learnt about the glorious benefits of ISAs, the next step is choosing the best stocks and shares ISA to suit your goals. We’ve tried and tested more than 15 platforms offering investment ISAs and here are our top picks.
"Using a stocks and shares ISA usually means that you can invest tax-free – but there is an exception.
When you buy US stocks using your investment ISA, you won’t have to pay any capital gains or dividend tax in the UK. However, if your US stock pays dividends, a withholding tax (WHT) of 15% will automatically apply.
There’s nothing you need to do about this and your provider will take care of it for you but it’s worth being aware of this when people say that you pay absolutely zero tax on investments held in stocks and shares ISAs. This is true for UK investments, but you may still have to pay a little to Uncle Sam in the US."
Yes, but this is only due to recent changes made to the ISA rules in April 2024. Previously, you could only open and pay into one stocks and shares ISA each tax year. Now, the floodgates have opened and you have the flexibility to open more than one stocks and shares ISA, and as many as your heart (or wallet) desires.
