You can split your annual allowance across the three types of ISAs:
- stocks and shares
- innovative finance
Don't break the golden rule though: You can only fund one of each type of ISA each tax year.
Keep in mind that if you qualify for a help-to-buy or lifetime ISA, any subscriptions you make to them also count as part of your annual allowance.
Let's paint a picture of how this could work:
You hold three cash ISAs from previous years. You may fund one of them with some or all of your annual allowance. Or you can open a brand new cash ISA and fund that instead. You can then put any allowance you have left over in one stocks and shares ISA and/or one innovative finance ISA – no matter how many of those you hold too.
