Thursday April 2nd 2026 is the last trading day of the 2025/2026 tax year in the UK.
This is the day to sell any stocks in your GIA invest account which show a loss.
Your capital gains allowance is £3k, so if you have made more gains in this tax year than £3k, it makes sense to sell those losing stocks now in order to reduce the year's total capital gains to get as near to 3k as possible.
On Tuesday April 7th you can move that cash into your ISA (up to 20k) and buy back the same shares if you wish.
If you need more cash to reach 20k, you can sell more shares to Bed-and-ISA them.
Given the volatile nature of the stock market, you might like to sell shares in your GIA only when Trump has released good news and the market is high (like today) but only buy shares in your ISA on bad news days when prices will be down.
Some people prefer to dollar cost average into their ISA.
