Government borrowing rises in September - what it could mean for businesses ahead of the Budget

Official figures show that UK government borrowing reached £20.2 billion in September - the highest for the month in five years. The figures, released by the Office for National Statistics (ONS), underline the financial pressures facing the Chancellor as preparations continue for next month’s Budget.
Borrowing, which measures the gap between government spending and income from taxes, was £1.6 billion higher than in September last year. The ONS said that although the government raised more through taxes and National Insurance, this was outweighed by higher spending, particularly on debt interest and inflation-linked costs.
Implications for the upcoming Budget
Higher borrowing means there is less room to manoeuvre in November’s budget. The rise in debt interest costs - nearly £10 billion in September alone - reduces the funds available for tax cuts or new spending commitments.
These figures are likely to make the Chancellor’s job more difficult when setting out her Budget plans. The Office for Budget Responsibility will update its forecasts alongside the Budget, setting out how much “headroom” the Chancellor has under her own fiscal rules. Many expect that the chancellor will need to raise taxes to meet those rules.
Analysts at Capital Economics estimate that around £27 billion may need to be raised, with households expected to carry much of that burden.
What might be in the Budget
Chancellor Rachel Reeves has been keen to emphasise that the government remains committed to manifesto promises not to raise the rates on income tax, VAT or National Insurance.
She has also made promises on taking “targeted action to deal with cost of living challenges” in the Budget. One idea suggests that the current 5% rate of VAT charged on energy could be reduced.
This suggests that any tax rises will at least be framed in such a way as to avoid the impression that people are receiving less in their pay packets.
Speculation around where tax rises could come from includes:
- Freezing tax thresholds. This is a stealthy way of bringing more people into higher rates of tax and increasing tax yield without being immediately felt by most.
- Cutting the employee rate of National Insurance, while adding the same amount to income tax. This would have a limited effect on those who are employed, but increase tax collected from pensioners, landlords and the self-employed.
- Reforming property taxes, such as replacing stamp duty with a property tax, making landlords pay more and removing principal private residence relief.
- Reducing the tax relief available on ISA and pension saving and the size of the tax-free lump sum that can be withdrawn.
