UK Tax Wedge Rises Fastest Among Rich Nations, OECD Finds
Lead: OECD Flags Record Rise in UK Tax Wedge
The Organisation for Economic Cooperation and Development reports that the UK’s tax wedge – the total tax burden on labour – jumped by 2.45 percentage points in 2025, the steepest increase among the 38 OECD members.
The Surge in Britain’s Tax Wedge
According to the OECD’s annual study, the rise was driven by Rachel Reeves’s 2024 autumn budget, which lifted employer National Insurance Contributions and allowed fiscal drag to intensify.
Numbers Behind the Rise: International Comparison
- UK tax wedge: 32.4% (still below the OECD average of 35.1%)
- Next biggest increase: Estonia, +1.95 pp
- Other >1 pp gains: Germany +1.34 pp, Israel +1.09 pp
- 24 of 38 OECD countries saw a rise; 11 fell and 3 were unchanged.
Implications for the UK Labour Market and Fiscal Policy
The higher tax burden adds pressure on low‑pay sectors such as hospitality, leisure and retail, where employment has already slipped. Labour’s promise not to raise taxes on workers is challenged by the inclusion of employer‑paid NICs in the wedge measure. The chancellor argues the steps are needed to repair public finances after 14 years of Conservative rule.
Outlook: Future Tax Burden and Economic Risks
The International Monetary Fund projects that UK taxes as a share of GDP will climb at the fastest rate in the G7 through 2031, especially if the Iran‑related global recession deepens. Continued fiscal drag and higher NICs could further suppress take‑home pay and exacerbate unemployment risks.
