Can I open the Lifetime ISA if I already have other ISAs?
Yes, you can open and add money to other types of ISAs (Cash ISAs, Stocks and Shares ISAs or Innovative Finance ISAs) alongside your Lifetime ISA. You’ll only be able to save into one Lifetime ISA each tax year.
You can contribute up to £20,000 across all your ISAs in the 2020/21 tax year, with up to £4,000 in your Lifetime ISA. The government bonus doesn’t count towards the £20,000 overall limit or the £4,000 Lifetime ISA limit.
