The Best Tax Month in History Still Wasn't Enough
July is supposed to be the good month. Self-assessment taxpayers settle up by the 31st, HMRC banks the windfall, and for four weeks a year the public finances look almost respectable. This July, provisional ONS figures put self-assessment receipts at a record £17.1 billion, the highest July haul since the deadline system began. A Reuters poll of economists had the month coming in close to balance on the strength of it. The government borrowed anyway: £1.8 billion, on the same release. Not a catastrophe by the standards of the year. But a month built to be the exception turned out to be the rule.
The tax take was the best it has ever been in a single month. The story is what happened on the other side of the ledger while nobody was looking. Welfare spending, uprated automatically each April against a formula nobody in Parliament revisits line by line, has been running ahead of forecast. Debt interest, swollen by the unusually large share of UK gilts linked to inflation, moves in lockstep with every CPI print whether the Treasury likes it or not. Public sector pay settlements agreed earlier in the year land as cash out the door now. Put record income against rising, largely automatic outgoings, and July's surplus becomes July's deficit. Nobody stole the money. It simply left through doors that open on their own.
The strongest version of the government's case is worth taking seriously, because it isn't nothing. Britain's index-linked gilt stock is a legacy of borrowing decisions made across four decades, not this Chancellor's design. The welfare uprating formula is statute, not discretion. A Treasury cannot decide, mid-year, to stop honouring either. If you inherited this exact machine, you would get this exact result, and calling that incompetence misunderstands what the word means. The machine was built to run this way.
Which makes it the point rather than the excuse. Net debt now sits at 94.1 per cent of GDP, a level Britain last carried in the early 1960s. Back then the country was paying down war debt through growth it could feel in real wages. Now it sits near a comparable level having built almost nothing to show for it, on a spending settlement nobody consciously chose in any single vote and everybody agreed to in a thousand smaller ones. Every individual link in that chain can defend its own decision. That is how a country ends up here.
The Bank of England held rates at 4 per cent the day before the July figures landed, decided by nine people on the Monetary Policy Committee, none of whom face an electorate. That leaves fiscal policy doing the adjusting alone, because the other lever has independently chosen not to move. Rachel Reeves will stand at the despatch box in the autumn holding a number that four unelected mechanisms built for her without her signature on any of them. The fiscal rule she is judged against, debt falling as a share of GDP within a rolling five years, predates her tenure and will outlast it.
I have refreshed the ONS release page more times this week than is defensible, so I will say plainly: these monthly figures get revised, sometimes by hundreds of millions, once the dust settles. Treat the exact number as provisional. Treat the pattern — record receipts losing to automatic spending — as the thing that keeps recurring regardless of which month you check.
None of the institutions responsible for July's £1.8 billion answer to a ballot. The OBR forecasts the path Reeves is judged against. The ONS counts what actually happened. The MPC sets the rate that decides how much of the gap is interest. The uprating formula, last legislated in a Parliament that has since dissolved twice over, decides how much of it is welfare. A Chancellor stands up in November to defend arithmetic she did not construct, in front of a public that never got a vote on any of its component parts. The best tax month in the country's history still wasn't enough, and the fault line runs through four rooms no elector has ever entered.
