Under the new ISA rules from 6 April 2024, you’re now allowed to contribute to more than one ISA of the same type in a single tax year (for example, two stocks & shares ISAs), as long as your total contributions across all ISAs stay within the annual limit (currently £20,000).
This means:
You can fund a Freetrade stocks & shares ISA even if you've already contributed to another provider’s stocks & shares ISA this tax year.
You can also contribute to different types of ISAs (e.g. cash ISA, Lifetime ISA, etc.) in the same year - again, provided the total doesn’t exceed the £20,000 limit.
