You can deposit up to £20,000 into your Chip Cash ISA each tax year. This is your annual ISA allowance, a limit set by the UK Government.
While there's a limit on new deposits each year, there is no maximum balance for the Chip Cash ISA. This means you can transfer in as much as you like from other ISAs you hold.
Please note: From 6 April 2027 cash ISA allowance is due to change for people under 65. The new maximum amount you can deposit into all your cash ISAs (across all providers) for the 2027/28 tax year will be £12,000. This is a reduction from the current £20,000 limit.
