Our Expert Opinion on Newcastle Building Society Newcastle Cash Lifetime ISA

This account suits first-time buyers saving towards a property costing £450,000 or less, or anyone under 40 who wants a tax-efficient pot they can access from age 60, and the 25% government bonus on up to £4,000 a year is the core appeal. The rate sits at 1.95%, which is a touch below what Bath Building Society's Lifetime ISA pays at 2.60% or Skipton's at 2.05%, so I would still check those before committing. The genuine catch here is the withdrawal penalty: if you take money out for any other reason, the 25% government charge effectively claws back more than just the bonus, meaning you lose 6.25% of your own contributions too.
