International tax matters become more complex depending on the number of countries and tax systems you are involved with. Before starting any business or personal endeavor that will result in your having to pay taxes, it is a good idea to educate yourself on the various tax codes and obligations that may be involved. Check with the revenue offices of each country for information on their tax regulations. Like the American tax system, those of other countries are constantly changing, often producing a confusing and complex tax situation for individuals and businesses. Whether you are considering involvement in a foreign business or are having questions about current tax difficulties, it may be helpful to consult a tax specialist or attorney familiar with international tax matters. These professionals may also be able to help you find ways to save money in your foreign financial affairs. (来源：专业英语学习网站 http://www.EnglishCN.com)
