The start of the new tax year on 6 April 2017 saw the launch of the Lifetime ISA (LISA), which was announced in the 2016 Budget. This is a new type of Individual Savings Account (ISA) designed to help you save for a first home or for your retirement at the same time. To be eligible, you have to be aged between 18 and 39 years old (up until your 40th birthday).
