Definition Tax-to-GDP ratio: 

This ratio is the total government tax collections divided by the country's GDP. Some countries, like Sweden, have a high tax-to-GDP ratio (as high as 54%). Other countries, like India, have a low ratio. When tax revenues grow at a slower rate than the GDP of a country, the tax-to-GDP ratio drops. Taxes paid by individuals and corporations often account for the majority of tax receipts, especially in developed countries.

Customs and duties paid by users of goods and services also make up a portion of tax receipts. (Investopedia)
