The thresholds that decide whether tax is due have not moved, while incomes, property values and business valuations have risen.
What the bulletin says
The figures are HMRC’s own, covering April to July 2026:
- Total tax and National Insurance £322.7 billion, which HMRC states is £19.1 billion higher than the same period last year.
- Income Tax, Capital Gains Tax and National Insurance together £189.8 billion, up £13.2 billion. That one line is about seven-tenths of the year-on-year increase.
- Inheritance tax £3.2 billion in four months, £0.1 billion higher than last year.
- Business taxes £31.6 billion, up £3.7 billion.
- VAT £64.8 billion (up £1.0 billion) and stamp taxes £6.9 billion (up £0.5 billion).
Reporting the same release on 21 August 2026, Money Marketing put capital gains tax receipts for the 2025/26 tax year at a record £22.2 billion, and noted Office for Budget Responsibility projections of £34.9 billion a year by 2030/31. Simon Martin of Utmost, quoted in that report, warned that the rising burden on gains from investments, property and business assets risks making the UK less attractive to internationally mobile investors.
The growth is concentrated in personal income and gains and in business taxes, which is where a business owner’s tax sits.
Set against seventeen years of house price growth and a decade of wage growth, a fixed £325,000 covers less than it did in 2009. A client can become liable without buying anything, because the value of the house rises. Nothing in the compliance cycle records the year a client crossed a threshold they were previously under. The accounts are filed and the return is submitted as before.
The available allowances are £325,000 of nil-rate band plus £325,000 transferred from the late spouse, and £175,000 of residence nil-rate band plus £175,000 transferred: £1,000,000 in total, with the residence element depending on the home passing to direct descendants and tapering where an estate exceeds £2 million.
Under the rules in force today the estate for inheritance tax is £950,000. It falls under the £1,000,000 of allowances and no inheritance tax is due. For deaths on or after 6 April 2027, most unused pension funds count in the estate (Finance Act 2026; HMRC technical note, Inheritance Tax on pensions, 11 May 2026). The same client under each set of rules, and the estate becomes £1,350,000. Taxable value £350,000, at 40%, is an inheritance tax bill of £140,000. The change is set out in when the pension joins the estate.
The increase comes from the rule change and the frozen threshold, with no change to the assets.
HMRC, 21 August 2026: £322.7 billion of tax and National Insurance collected in April to July 2026, £19.1 billion more than the same four months of 2025.
