Isa savers under 65 have ‘last chance’ in the new 2026-27 tax year

From April 6 2027, however, changes will mean that, while the total annual Isa allowance will still be £20,000, adults aged under 65 will only be able to put away up to £12,000 in a cash Isa, with the remaining £8,000 allowance potentially going into stocks and shares.
