What are the key dates and allowances for 2025/26? MoneyWeek has an experienced investor’s end of tax year checklist here (linked below…)
“High net worth investors with multiple sources of income, or complex tax arrangements, often find that planning for the end of tax year deadlines is a headache – and this year it risks becoming a migraine. There were yet more tweaks to taxes at the 2025 Budget, making affairs even more complicated at a time when tax rates remain at the highest levels in peacetime. So, investors wanting to reduce their tax bills should act now rather than leaving everything to the last minute.” – Susannah Streeter
The clock is ticking down before the end of the 2025/26 tax year, when any tax-free savings and investment allowances are lost. For experienced investors, though, the deadline for some tax-saving schemes is even earlier.
