Macro Effects of a Rising UK Tax Burden

Geoff Riley

16th May 2026

Share this content:

The UK tax burden is projected to hit a post-war high of 38.5% of GDP by 2030, driven by fiscal drag, higher dividend taxes, and rising employer national insurance.

This upward shift reduces consumer spending and Aggregate Demand, creating a negative accelerator effect on investment, business profits, and employment. Furthermore, elevated tax rates disincentivise labour market participation—exacerbating shortages and cost-push inflation—while threatening competitiveness by deterring inward Foreign Direct Investment (FDI).

However, the revenue helps stabilise public service funding and the debt-to-GDP ratio, and remains lower than European peers like France and Germany.
