Read GOV.UK guidance on ISAs and Lifetime ISAs

The GOV.UK pages on Individual Savings Accounts (ISAs) and Lifetime ISAs explain the different types of tax‑efficient savings accounts, eligibility rules, and how interest and returns are treated for tax purposes. The guidance helps you decide which ISA wrapper suits your goals (cash, stocks & shares, Lifetime ISA) and how to use transfers to consolidate savings. Using the right tax‑efficient account can increase long‑term net returns by avoiding unnecessary tax on interest and investments.
