UK public finances hit historic high with £30.4 billion surplus in January 2026, but year-to-date borrowing remains substantial
The UK’s public sector finances have reached an historic milestone, with the Office for National Statistics confirming a record monthly surplus of £30.4 billion in January 2026—the largest since official records began in 1993. The figure exceeded even optimistic government forecasts and represents a dramatic turnaround from the same month a year earlier, when the public sector recorded just a £14 billion surplus.
The January data comes as welcome relief to the Treasury following months of fiscal pressure. The surplus was £15.9 billion higher than January 2025 and comfortably beat the Office for Budget Responsibility’s November 2025 forecast by £6.3 billion. At a time when government finances have come under sustained scrutiny, this strong monthly performance provides evidence that the public finances are moving in the right direction.
The exceptional performance owes much to a significant boost in self-assessment tax receipts. Every January, the UK’s self-employed population and higher earners submit self-assessment tax returns, creating a predictable annual spike in government income. This January proved particularly generous, with combined self-assessed income tax and capital gains tax receipts reaching £46.4 billion—a rise of £10.5 billion compared with January 2025. This seasonal effect explains much of the monthly surplus but also highlights how tax receipts have strengthened across the economy.
Broader tax revenue figures underscore improving collections. Central government tax receipts increased by £46.2 billion to £698.4 billion during the month. Income tax rose by £28 billion, reflecting both inflation and the impact of frozen personal allowance thresholds, which draw more taxpayers into higher tax bands. Value Added Tax receipts climbed by £7.8 billion, suggesting robust consumer spending, whilst Corporation Tax increased by £4.7 billion as business profits have held up better than some anticipated.
National Insurance contributions also surged, rising by £26.1 billion as the increased employer National Insurance contributions introduced on 6 April 2025 took full effect during the financial year. This change, introduced as part of the government’s fiscal consolidation efforts, has delivered substantial additional revenue but has remained contentious amongst businesses concerned about employment costs.
Yet the headline surplus masks a more complex underlying picture. The year-to-date deficit for the first ten months of the financial year stands at £112 billion—a figure £8 billion higher than the government’s budget plan, despite being £15 billion lower than the same period in 2024-25. This means that whilst the monthly surplus was exceptional, the cumulative position remains constrained. Over the financial year to January 2026, the government borrowed £112.1 billion, representing a reduction of 11.5 per cent compared with the previous year. However, this remains the fifth-highest ten-month borrowing figure on record when adjusted for historical comparison.
The current budget deficit—borrowing required to fund day-to-day public sector activities excluding investment—totalled £55.9 billion for the year to date, a reduction of 24.3 per cent compared with the same period previously. This improvement reflects stronger tax revenues offsetting higher current spending, which has risen 6 per cent to £1,070 billion. This spending increase reflects public sector pay awards, higher supplier costs, and uprating of welfare benefits in line with inflation.
Public sector net debt stood at £2,867 billion on 31 January 2026, representing 93.2 per cent of gross domestic product. The January surplus reduced debt by £56 billion during the month, contributing to the overall reduction in net debt as a percentage of GDP. However, the absolute level of debt remains historically elevated, constraining fiscal flexibility.
The data demonstrates that improved tax revenues are playing a crucial role in narrowing the fiscal gap. The challenge for government will be sustaining this revenue growth whilst managing rising public spending demands. Economists have noted that some of the recent income tax improvements reflect fiscal drag—where frozen allowances push more people into higher tax bands—rather than underlying economic dynamism. This raises questions about tax system sustainability and the potential need for policy decisions about allowance thresholds in future years.

- Self-assessment tax receipts reached £46.4 billion, up £10.5 billion year-on-year, providing the dominant driver of the surplus
- Year-to-date borrowing of £112.1 billion represents an 11.5 per cent reduction but remains the fifth-highest on record, indicating underlying fiscal challenges persist
- Tax receipts across income tax, VAT, and Corporation Tax all increased substantially, reflecting improved economic performance
What This Means for Kent Residents
For Kent residents and businesses, the stronger public finances offer mixed signals. Higher tax revenues from businesses and self-employed individuals—including many operating within Kent’s diverse economy—reflect economic activity in the region. However, with public sector debt remaining elevated and year-to-date borrowing still significantly above forecast, the government’s scope for new spending commitments or tax cuts remains constrained. Households should expect continued focus on fiscal consolidation, potentially affecting public services and welfare support. For Kent businesses, particularly those in retail, hospitality, and small enterprise sectors reflected in the VAT data, the stronger tax collection suggests consumer spending remains resilient, though rising National Insurance costs continue to weigh on employment decisions.
