RE: Have we broken £11 barrier?11 Sep 2025 12:17
Here’s a roundup of recent stories, proposals, debates, and political reactions in the UK around the idea of “taxing ISAs” or changing the tax-free status / allowances of ISAs (Individual Savings Accounts). This includes what’s been actually proposed, what’s been ruled out, who stands where, and what the implications might be.
What has been proposed, discussed or leaked
1. Reducing the cash ISA allowance
• The Chancellor, Rachel Reeves, has reportedly been considering cutting the amount people can put into cash ISAs each year, potentially down from £20,000 to as low as £4,000. 
• The aim seems to be to encourage people to invest more via stocks & shares ISAs rather than keeping large amounts in low-yield cash, which is more costly in real terms due to inflation. 
2. “British ISA” proposal
• There has been discussion of introducing a new kind of ISA (“British ISA”) or modified version that would focus on investments in UK firms. For example, enable tax-free investing in UK equities/debt to encourage investment into domestic businesses. 
• This could be alongside or in addition to existing ISA types. 
3. Political pressure & “tax on savers” framing
• Opponents of the proposed ISA changes (e.g. SNP, financial institutions, savings bodies) have argued that cutting the cash ISA allowance is effectively a “tax on savers,” particularly hitting people relying on safe savings rather than investment. 
• Warnings that reducing the cash ISA allowance could reduce the funding available to building societies, which use savings deposits (including from ISAs) to fund mortgages etc. 
4. Consultation / Exploration, but no confirmed action yet
• The Chancellor has confirmed that while reform is being explored, as of mid-2025 the annual tax-free ISA allowance has not been reduced from £20,000. 
• There is an ongoing consultation into how the ISA market could be reformed. Changes might target cash ISAs specifically. 
⸻
What has been ruled out / reversed
• In May 2025, after much speculation and pressure, the Chancellor ruled out cutting the £20,000 tax-free ISA allowance—i.e. she said she will not reduce that limit. 
• Despite earlier rumours, the big cut to cash ISA to something like £4,000 was not enacted then.
