Tax Revenue as Percentage of GDP — – Tax Revenue (% of GDP) refers to the total tax revenue collected by the central government, expressed as a percentage of Gross Domestic Product (GDP). Tax revenue consists of compulsory, unrequited payments made by individuals and businesses to the government for public purposes. The indicator measures the relative size of tax collections compared with the overall economy and is widely used to assess a government's revenue-generating capacity, fiscal performance, and tax effort.
Measured as a Percentage, the dataset covers 2015–2024 and shows a stable regional tax-to-GDP ratio, increasing from 19.20% in 2015 to 19.71% in 2024, with only moderate fluctuations throughout the decade. This consistent trend reflects the region's mature tax systems, diversified economies, and effective fiscal institutions.
Regional performance is driven by major economies including the United Kingdom, France, and Italy, all of which maintained relatively high tax-to-GDP ratios. The UK increased from 24.92% in 2015 to 26.89% in 2024, while France and Italy remained largely within the 23–26% range. Among Nordic countries, Denmark recorded the region's highest tax ratio, peaking at 35.16% in 2021, while Sweden consistently exceeded 27%. Other economies, including the Netherlands, Finland, Spain, Germany, and Turkey, also contributed to regional stability through relatively consistent tax revenue performance.
The dataset is valuable for policymakers, economists, financial institutions, investors, and researchers evaluating fiscal sustainability, taxation efficiency, and government revenue across the region. It supports regional and global benchmarking, tax policy evaluation, trend analysis, and revenue forecasting. Additionally, it contributes to research on public finance, macroeconomic stability, fiscal resilience, and sustainable economic development by illustrating how tax revenues support public services, infrastructure investment, and long-term economic growth across Europe & Central Asia.
