Conventions can deal with many issues, such as. B taxation of different categories of income (i.e. company profits, royalties, capital gains, labour income, etc.), methods of eliminating double taxation (e.g. B on exemption method, accounting method, etc.) and provisions such as mutual exchange of information and assistance in tax collection. The agreement is the standard for an effective exchange of information within the meaning of the OECD Initiative on Harmful Tax Practices. This agreement, published in April 2002, is not a binding instrument, but includes two model bilateral agreements. This agreement was based on a number of bilateral agreements.  Many countries have entered into tax treaties (also known as double taxation treaties or DAs) with other countries to avoid or mitigate double taxation.
