Within the European Union, Member States have concluded a multilateral agreement on the exchange of information.  This means that they will provide each (its counterparts in the other jurisdiction) with a list of persons who have applied for exemption from local taxation because they are not established in the state where the income is generated. These people should have declared that foreign income in their own country of residence, so any difference suggests tax evasion. Bulgaria Bulgarian tax agreements and international agreements The EM method obliges the country of origin to collect tax on income from foreign sources and transfer it to the country where it was created.

While the double taxation conventions provide for the exemption from double taxation, Hungary has only about 73. This means that Hungarian citizens who receive income from the 120 countries and territories with which Hungary does not have a contract will be taxed by Hungary, regardless of the tax that has already been paid elsewhere. For example, the double taxation contract with the United Kingdom provides for a period of 183 days during the German fiscal year (corresponding to the calendar year); For example, a UK citizen could work in Germany from 1 September to 31 May (9 months) and then claim to be exempt from German tax.
Since agreements to avoid double taxation will guarantee the protection of the incomes of certain countries, a DBA was signed between the Czech Republic and Korea in January 2018.  The treaty creates double taxation between these two countries. In this case, a Korean resident (person or company) who receives dividends from a Czech company must compensate czech tax on dividends, but also Czech tax on profits, profits of the company that distributes the dividends. The contract is for the taxation of dividends and interest. Under this contract, dividends paid to the other party are taxed at a maximum of 5% of the total dividend amount for corporations and individuals. This contract reduces the tax limit on interest paid from 10% to 5%. Copyright in literature, works of art, etc., remain tax-exempt. For patents or trademarks, a maximum tax rate of 10%.
