The Chancellor reversed the planned cut to the cash ISA contribution allowance and the addition of tax on cash ISA interest in last week’s Budget, but tax on savings interest and property income will rise by a further two percentage points from April 2027.
Combined with the increase already planned, that takes savings tax rates to 24%, 44% and 49%. The higher rates will also apply to gains on investment bonds, which are taxed as savings income.
To put this in context, a higher-rate taxpayer earning 2.5% interest on savings outside an ISA would keep around 1.4% after tax from April 2027. If inflation stayed at today’s 3.5%, that money would be losing value in real terms. By contrast, Capital Gains Tax and dividend tax rates are unchanged, widening the gap between how cash savings and investments are taxed.
It may be a good moment to consider whether the level of cash you hold still reflects your longer-term goals.
Are you making full use of your ISA and pension allowances?
And how does any savings or rental income fit within your wider tax position?
Everyone’s situation is different, so if you’d like to talk through what these changes mean for you, we’d be happy to arrange a conversation.
