I agree with all of RM’s proposals especially the big yield ones: restricting tax relief on pension contributions, bringing back the investment income surcharge, getting rid of the lower rate of NIC for top earners, capital gains tax on the PPR.
I would definitely cap ISA contributions in a lifetime despite the relatively little additional tax yield. If someone has invested the maximum in ISAs since they began (and maybe had TESSAs before that) then they would now have over £300,000 invested. With an average yield, it’s equivalent to doubling the tax free personal allowance each year.
Earlier in this administration when there was talk of changing the ISA allowance to encourage more investment in stocks and shares, I thought Reeves would do something about it then but she didn’t. £100,000 seems reasonable.
About a trillion is currently invested in ISAs in the UK. A J Bell estimated that up to 2.5 million people max out their ISA investment each year. I figure if you have £300,000 squirrelled away and can save £20,000 a year you can pay a bit more tax.
