Every Budget sounds the same on the evening news. The Chancellor stands up, reads a long speech, and the real detail is buried in the supporting documents. The 2026 Budget delivered by Rachel Reeves was no different on the surface, but underneath it makes several quiet changes that will affect most households over the next five years.
Below is the practical version. No jargon, no party politics, just what changed and where to look next if it applies to you.
Personal allowance: still frozen
The personal allowance remains at £12,570 and the freeze has been extended to April 2030. That is the single change with the biggest long-term impact. As wages and pensions rise with inflation, more people are pulled into paying tax or paying at a higher rate. This is sometimes called fiscal drag.
If your gross income has gone up by even a small amount, run your numbers through our salary calculator to see whether you have slipped into the basic or higher rate band for 2026/27.
Pensions and inheritance tax
From April 2027, most unused pension pots will be counted as part of your estate for inheritance tax. This is the most talked-about change in the Budget and it reverses a decade-old planning tactic used by people who wanted to pass wealth down to children or grandchildren.
If you have a SIPP or workplace pension you were planning to leave untouched, it is worth checking how the new rules will apply in your case. We have covered this in more detail in our pension inheritance tax guide, and you can model the overall position with our pension calculator.
A possible "mansion tax" on high-value homes
The Chancellor confirmed a council tax surcharge on residential properties valued above £2 million from 2028. It is a small group of homes in absolute terms, but the decision has set a direction that could filter into wider valuation bands over time. If you own a high-value property in London or the South East, watch the detail as it emerges.
National insurance and employer costs
Employee National Insurance stays at 8 per cent for most workers. Employer National Insurance was not reduced, which keeps pressure on recruitment and pay rises in lower-margin businesses. Use our employer cost calculator if you run payroll and want to see the full cost of an extra hire.
ISAs and savings
The overall ISA allowance stays at £20,000, but the cash ISA limit has been trimmed as part of a push to encourage more investing. If you use cash ISAs for emergency money, check whether you need to split your saving between cash and stocks and shares from April 2026.
Capital gains tax
The annual CGT allowance remains at £3,000, and the rates are unchanged. The Chancellor did not close the gap between income tax and CGT this time, but most commentators expect pressure to continue in future Budgets.
What it means for you
Most employees will notice the frozen allowance more than any headline figure. Higher earners and people with larger pensions will feel the inheritance tax change the most. Landlords and business owners will need to look carefully at the small print rather than the speech.
The easiest way to turn a Budget into real numbers is to rerun your own figures after each change. Our calculator library has been updated for 2026/27 so you can see the practical effect on your pay, your pension, and your savings in a few clicks.
