Tax shelters seem to be especially despised these days — both the people who use them and the countries that harbor them. With so many countries struggling financially, it’s hard to sit back and do nothing to the uber-wealthy individuals and corporations that hide their billions offshore. This past Friday, each G20 nation pledged to make greater efforts to work together to fight tax evasion. This also means they will strive to do more to enforce the tax laws within the borders of their own countries. Besides Switzerland, one of the most infamous tax havens, there are several other nations that have transparency problems, including Monaco, Panama, and Uruguay. Moving forward, the goal will be to get these other nations to sign on as well.
