Lifetime ISA rules to know

Open between ages 18 and 39; pay in until you're 50.
Pay in up to £4,000 a year (part of your overall £20,000 ISA allowance) for a 25% bonus - up to £1,000 a year.
Use it for a first home up to £450,000, or from age 60 for retirement.
Withdraw for anything else and you pay a 25% government charge - which can leave you with less than you put in.
