Double taxation can also take place within a single country. This usually occurs when sub-national jurisdictions have tax powers and jurisdictions have competing rights. In the United States, a person can legally have only one residence. However, if a person dies in different states, anyone can say that the person was a resident in that state. Intangible personal property can then be imposed by any state asserting a right. In the absence of specific laws prohibiting multiple taxation and as long as total taxes do not exceed 100% of the value of personal material assets, the courts will allow multiple taxation. [Citation required] The revised Convention on the Prevention of Double Taxation between India and Cyprus, signed on 18 November 2016, provides for a tax on capital gains from the disposal of shares instead of a home-related tax under the Convention on the Prevention of Double Taxation, signed in 1994. However, a grandfather clause is provided for investments made before April 1, 2017 and for which capital gains continue to be taxed in the country where the taxpayer is based.

As a result, cross-border tax treatment is becoming one of China`s major financial and commercial projects, and cross-border tax problems are growing. In order to solve these problems, multilateral tax treaties between countries that can legally help businesses on both sides avoid double taxation and find solutions to tax issues are put in place. In order to implement China`s «comprehensive» strategy and to help domestic companies adapt to globalization, China has committed to promoting and signing multilateral tax agreements with other countries in order to achieve common interests. At the end of November 2016, China officially signed 102 double taxation agreements. 98 of them have already come into force. In addition, China has signed an agreement to avoid double taxation with Hong Kong and the Macao Special Administrative Region. China also signed an agreement in August 2015 to avoid double taxation with Taiwan, which has not yet entered into force. According to the Chinese tax administration, the first agreement to avoid double taxation was signed with Japan in September 1983.

The last agreement was signed with Cambodia in October 2016. With regard to the situation of state disorganization, China would continue the agreement signed after the disruption. For example, in June 1987, China signed for the first time an agreement to avoid double taxation with the Socialist Republic of Czechoslovakia. In 1990, Czechoslovakia was divided into two countries, the Czech Republic and the Slovak Republic, and the initial agreement with the Czechoslovakian Socialist Republic was continuously used in two new countries. In August 2009, China signed the new agreement with the Czech Republic. And when it comes to the particular case of Germany, China continued to conclude the agreement with the Federal Republic of Germany after the reunification of two Germanys. China has signed an agreement with many countries to avoid double taxation.
