Tax payments (number)
To make the data comparable across countries, several assumptions are made about businesses. The main assumptions are that they are limited liability companies, they operate in the country's most populous city, they are domestically owned, they perform general industrial or commercial activities, and they have certain levels of start-up capital, employees, and turnover. 

The Doing Business methodology on business taxes is consistent with the Total Tax Contribution framework developed by PricewaterhouseCoopers (now PwC), which measures the taxes that are borne by companies and that affect their income statements. However, PwC bases its calculation on data from the largest companies in the economy, while Doing Business focuses on a standardized medium-size company.
Tax payments by businesses are the total number of taxes paid by businesses, including electronic filing. The tax is counted as paid once a year even if payments are more frequent.
