ISAs

A cash ISA pays interest tax-free. You can put up to £20,000 a year into adult ISAs, across cash and stocks and shares. A Lifetime ISA has a £4,000 yearly limit inside that £20,000, and a withdrawal charge if the money comes out early.

A flexible ISA lets you take money out and put it back in the same tax year. How that works
