If you are thinking of starting a business in another country, a resource that I highly recommend is World Bank’s DoingBusiness.org website.
Being from the premier international organization, the site has loads of economic information and studies on business environments including taxes as well as an extensive collection of business laws. More importantly to entrepreneurs, the site specifies the requirements asked in that country when you start or even close a business.
If you are looking to expand globally, make DoingBusiness.org your first stop.
