The Individual Savings Account (Amendment) (No. 2) Regulations 2026 updates ISA rules with three key changes: a £12,000 annual subscription cap for cash ISA accounts held by individuals aged 64 or under, new restrictions on money market funds within stocks and shares ISAs, and a charge on interest generated from cash deposits held in stocks and shares or Innovative Finance ISAs. Related provisions for subscriptions, transfers, tax treatment and reporting have been amended accordingly, with outdated age requirements for account opening also removed.
