Inclusions and exclusions
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.
The data includes compulsory tax payments collected by the central government, such as taxes on income, profits and capital gains, payroll taxes, property taxes, taxes on goods and services (including VAT, GST, and excise duties), taxes on international trade, customs duties, and other taxes recorded under the IMF Government Finance Statistics (GFS) framework. The indicator is expressed as a percentage of GDP using standardized national accounts and government finance statistics.

It also excludes fines, penalties, most social security contributions, refunds treated as negative revenue, and informal or unrecorded tax collections not captured in official government finance statistics. For many countries, the indicator reflects central government tax revenue only and may not include taxes collected by state, provincial, or local governments.
