Global Corporate Tax Rates in 2015

This is a curated list of Global Corporate Tax Rates. Click on the bar to show more details, click again to close the pop-up.

Built with blockbuilder.org

Data Source

Fetched from KPMG's Corporate tax rates table.

Known Issue

If the country has no data, I set the width of the bar to 0 px. Due to this configuration, you can't see the details of the country because you can't find any place to be clicked.

Still working on a solution. All suggestions are welcome.
