In countries where gambling is legal, land-based and online casinos are taxed on their Gross Gaming Revenue (GGR). Each country works it out differently, but generally the tax is calculated as a percentage of net profits and is meant to benefit local communities and the economy. Governments the world over aim to strike a balance between bringing in tax revenue, while still encouraging investors and allowing growth in the gambling industry. It’s no surprise then, that tax rates vary quite widely from country to country.
