What you should know about this indicator

  • Taxes are mandatory payments to the government that are not made in exchange for a specific good or service.
  • Taxes on income, profits, and capital gains (TIPCG) are taxes imposed on the income of individuals and corporations, including wages, business profits, and capital gains from the sale of assets.

How is this data described by its producer?

The variable Taxes captures tax collected regardless of sources (i.e., unless otherwise defined, this includes resource-based taxes). These follow the definition of taxes found in both the IMF’ Government Finance Statistics Manual (GFSM) and OECD Revenue Statistics Interpretive Guide as ‘compulsory, unrequited …’ payments to the government (IMF 2014; OECD 2020).

Direct taxes include taxes on income, profits and capital gains, taxes on payroll and workforce as well as taxes on property. Please note that the total values of direct taxes may sometimes exceed the sum of the aforementioned sub-components, owing to revenue that is unclassified among these subcomponents. When specified as direct taxes excluding resource revenue, direct taxes comprise non-resource taxes on the mentioned sub-components (e.g., excluding corporate taxes accruing from entities engaged in the extraction of natural resource).

Taxes on income, profits, and capital gains (TIPCG) are always reported exclusive of social contributions. The total value of TIPCG may sometimes exceed the sum of the positions displayed in individuals and corporations and other enterprises, due to revenues that are unallocated between the two.

Sources and processing

This data is based on the following sources

UNU-WIDER – Government Revenue Dataset (GRD)

The GRD aims to present a complete picture of government revenue and tax trends over time and allows for analysis at the country, regional or cross-country level. Where possible, figures are expressed both inclusive and exclusive of natural resource revenues, which helps to overcome a major obstacle to cross-country comparisons in existing data sources.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.

Notes on our processing step for this indicator

The source provides their data with caution notes, classifying them as follows:

  1. Accuracy, quality or comparability of data questionable.
  2. Un-excluded resource revenues/taxes are significant but cannot be isolated from total revenue/taxes.
  3. Un-excluded resource revenue/taxes are marginal but non-negligible and cannot be isolated from total revenue/taxes.
  4. Inconsistencies with social contributions.

We have excluded from our dataset the observations flagged with caution note 1.
