### Introduction
- WoRLD is a comprehensive panel data set tracking government revenue trends since the early 1980s, built entirely from IMF data and organized according to the Government Finance Statistics Manual.
- Coverage: data for 195 countries, including 191 IMF member countries.
- Purpose: to provide consistent, comparable time-series on the level and composition of revenues (tax and nontax) to support policymakers, researchers, and the public.
- Quality assurance: country data are sourced from IMF surveillance and lending activities and discussed during consultations with national authorities, enabling cross-country comparisons and robustness for countries with developing statistical systems.

### Key updates in the 2026 release
- Country and time coverage:
  - Number of countries tracked increased from 193 to 195 (Aruba and Liechtenstein added).
  - Temporal coverage extended through 2024 (previously up to 2022).
- Data and methodological changes:
  - Incorporation of revised GDP figures for several countries, including GDP rebasing and alignment of GDP series with fiscal years where applicable.
  - Updates to revenue series definitions and values, including improved tax revenue composition detail and filling previously missing components (for example, components of taxes on income and profits or sales and production).
  - Revision of variable “SalGType” to indicate presence of value-added tax and to include implementation dates for countries that implemented it in 1980 or after.
- Scope of updates to recent years:
  - Data for 2020–22 from the previous WoRLD version have been updated to reflect governments’ latest revisions.
  - Note: The composition of tax revenue is missing for certain countries for 2024 because of the update cycle and availability of data at the IMF and will be rectified in the 2027 update.

### Data quality checks and descriptive statistics
- Residuals (difference between each main series and its components) are not significantly different from zero; decimal adjustments account for mean/min/max values reported in Table 2.
- Descriptive statistics of residuals (percent of GDP) from Table 2:
  - TaxInc — Mean: −4.73E-09; Min: −5.8E-05; Max: 3.02E-05
  - TaxRev — Mean: −1.01E-08; Min: −6E-05; Max: 3.89E-05
  - TaxSal — Mean: −3.90E-09; Min: −3.9E-05; Max: 5.17E-05
  - TotRev — Mean: −2.11E-09; Min: −1.4E-05; Max: 1.13E-06
- Table 1 overview (coverage and mean values): the 2026 updates produce only slight shifts in average values of main revenue components, with maximum variation of 0.11 percentage points of GDP for total revenue, tax revenue, social contributions, grants, and nontax revenue.

### Key highlights and findings
- Global aggregates:
  - Government total revenue has been broadly stable, around 30 percent of GDP since the early 2000s.
  - Tax revenues increased slightly by about 1.5 percentage points of GDP over the same period.
  - Tax revenue accounted for roughly 57 percent of total government revenue in 2024.
- Revenue composition and importance of nontax revenue:
  - A substantial portion of government resources comes from nontax revenue: natural resource extraction (oil, gas, minerals), grants, dividends from state-owned enterprises, social contributions, and fees/other nontax instruments.
- Income-group differences:
  - Advanced economies:
    - Total revenue broadly stable at around 38 percent of GDP.
    - Stability mainly driven by tax revenue and social contributions.
  - Emerging market economies:
    - Total revenue shows an upward trend driven by increases in tax revenue and other nontax revenue.
  - Low-income developing countries:
    - Total revenue has been trending down since 2007, with decreases in grants and nontax resource revenue.
- Regional patterns:
  - Europe: consistently highest ratios in both total and tax revenue with minor variation over time.
  - Asia and Pacific: pronounced upward trajectory in total revenue with steady gains in tax revenue, especially since the early 2000s.
  - Western Hemisphere: gradual increases in both total revenue and tax revenue.
  - Africa: increase in tax revenue over time but remains the lowest in overall revenue levels.
  - Middle East and Central Asia: more fluctuation in total revenue and low, slowly growing tax revenue, reflecting heavier dependence on nontax resource revenue.
- Cross-period country dispersion:
  - Comparing 2000–02 and 2022–24, advanced economies are tightly clustered (more stable revenue ratios), while emerging market and low-income developing countries show wider dispersion, with several countries recording sizable gains since the early 2000s.

### Conclusion and outlook
- The 2026 WoRLD release provides a more extensive and consistent data set for revenue and fiscal policy analysis through broader country and time coverage, definitional improvements, and enhanced data consistency.
- Analytical value: strengthens cross-country and time comparisons of government revenue trends for policymakers and researchers.
- Update schedule: WoRLD will continue to be updated annually; the next release will incorporate data for 2025 and revisions for 2023 and 2024.

- Coverage: data for 195 countries, including 191 IMF member countries.
- Purpose: to provide consistent, comparable time-series on the level and composition of revenues (tax and nontax) to support policymakers, researchers, and the public.
- Quality assurance: country data are sourced from IMF surveillance and lending activities and discussed during consultations with national authorities, enabling cross-country comparisons and robustness for countries with developing statistical systems.

- Data and methodological changes:
  - Incorporation of revised GDP figures for several countries, including GDP rebasing and alignment of GDP series with fiscal years where applicable.
  - Updates to revenue series definitions and values, including improved tax revenue composition detail and filling previously missing components (for example, components of taxes on income and profits or sales and production).
  - Revision of variable “SalGType” to indicate presence of value-added tax and to include implementation dates for countries that implemented it in 1980 or after.

  - Data for 2020–22 from the previous WoRLD version have been updated to reflect governments’ latest revisions.
  - Note: The composition of tax revenue is missing for certain countries for 2024 because of the update cycle and availability of data at the IMF and will be rectified in the 2027 update.

    - TotRev — Mean: −2.11E-09; Min: −1.4E-05; Max: 1.13E-06
- Table 1 overview (coverage and mean values): the 2026 updates produce only slight shifts in average values of main revenue components, with maximum variation of 0.11 percentage points of GDP for total revenue, tax revenue, social contributions, grants, and nontax revenue.

### Key highlights and findings

Note: The columns “Countries” and “Observations” are counts, and “Coverage” is the percentage of available data points to total data points. This percentage is low for certain series because some countries do not have revenues from certain sources—for example, not all countries have corporate income tax revenue from oil and gas companies.
