The Finance Bill was never the fiscal system

Public debate is over-concentrated on one instrument when three should be in view. By the time the Bill is published, the decisions that matter have already been taken.

Every year the Finance Bill arrives and the argument starts. Every year the argument is late. The Bill is a revenue tool, not the fiscal system itself: it sits downstream of the Budget Policy Statement, the Medium-Term Expenditure Framework and the sector ceilings set months earlier. A debate that begins at publication is a debate about the last ten per cent of the decision.

The harder number is on the other side of the ledger. Debt service absorbed about 69 per cent of ordinary revenue in FY 2024/25. The IMF Debt Sustainability Framework thresholds for low-income countries range from 14 to 23 per cent. At that level, new revenue is not expanding productive capital; it is servicing debt. Raising more of it without addressing expenditure credibility changes who pays, not what the money buys.

Fiscal resistance is often read as a communications failure. It is more usefully read as an accountability mechanism: taxpayers withdrawing consent from a system whose expenditure they cannot verify. That reading points at a different set of remedies, and they sit with the Treasury, Parliament, the Controller of Budget, the Central Bank, civic actors and development partners rather than with any single Bill.
