Policy paper: Cash ISA limit reduced to £12,000 from 2027
The UK government announces a lower annual limit for cash Individual Savings Accounts (ISAs), changing how much individuals can invest in cash ISAs each tax year from 6 April 2027. The document outlines who is affected, what changes are being made, and how the new limit will operate alongside existing ISA rules. It also offers explanations of the intended effects and the practical steps savers may need to consider.
What is changing
The annual subscription limit for cash ISAs will be reduced to £12,000 for individuals under 65. This affects how much money a person can put into a cash ISA in a single tax year. The changes are described as part of a regulation update to ensure the ISA rules function as intended. The document specifies that the new limit applies to cash ISAs and details any interaction with existing ISA products and other allowance types.
Who is affected
Individuals under 65 who use cash ISAs will have a lower maximum annual contribution starting from the 2027/28 tax year. The policy paper also notes rules intended to ensure the limits operate correctly, which may affect how contributions are counted across accounts and how transfers between cash ISAs are treated under the new limit.
Practical steps for savers
Review current ISA holdings and yearly contribution plans to see how the £12,000 limit might affect this year’s planning. If you already expect to exceed the new limit, consider timing contributions, or using other ISA types (such as stocks and shares ISAs) where appropriate. When transferring funds between cash ISAs, verify how the transfer counts toward the new limit. Keep an eye on HMRC guidance for any transitional rules or exceptions as the policy implementation proceeds.
Limits, questions and where to read more
