UK Public Finances Record Unprecedented £30.4 Billion Surplus
London, 20 February 2026 – The United Kingdom’s public finances have reached a historic milestone, recording a record monthly budget surplus of £30.4 billion for January 2026. This figure represents the largest surplus since monthly records began in 1993, providing a significant fiscal boost for Chancellor Rachel Reeves ahead of the upcoming spring economic forecasts. The surplus was driven by a substantial surge in tax receipts, particularly from Capital Gains Tax and National Insurance, alongside a reduction in debt interest costs.
Record Tax Receipts Drive Fiscal Turnaround
The £30.4 billion surplus in January marks a sharp reversal from the £11.6 billion deficit recorded in December 2025. Analysts attribute this performance to a “bumper month” for the Treasury, as self-assessment tax returns and higher employer National Insurance contributions flowed into the government’s coffers. Additionally, falling inflation—which recently dropped to 3 per cent—has helped lower the interest payments the government must pay on inflation-linked debt.
While the news has rallied the FTSE 100 and improved the UK’s economic outlook, the Chancellor remains under pressure to address long-term spending requirements. Local authorities continue to report significant budget gaps, with some councils facing shortfalls of over £13 million for the 2026/27 financial year. Furthermore, a new student loan repayment structure, known as “Plan 5,” is set to be introduced on 6 April 2026, marking a shift in how the government manages education-related assets.

Frequently Asked Questions
Why is there always a surplus in January?
January is traditionally a strong month for the UK Treasury because it is the deadline for self-assessment tax returns. This leads to a seasonal spike in receipts from Income Tax and Capital Gains Tax that often results in a monthly surplus, even if the government is in a deficit for the full financial year.
What are the “Fiscal Rules” mentioned in UK budgets?
Fiscal rules are self-imposed targets set by the government to manage public debt and borrowing. They have evolved significantly since 1997, when Gordon Brown introduced the “Golden Rule,” which stated that the government should only borrow to invest and not to fund current spending over the course of the economic cycle.
How does inflation affect the UK budget?
Inflation impacts the budget in two primary ways: it can increase tax revenue as nominal wages and prices rise (fiscal drag), but it also increases the cost of servicing “index-linked” government bonds. The recent fall in inflation to 3 per cent has been a key factor in reducing the government’s debt interest bill this month.
