Is this possible?
Depending on the tax laws of the country you move to and the country you are leaving, you may or may not have to pay taxes in both countries. Some countries have tax agreements with each other to avoid double taxation, while others tax residents on their worldwide income. For example, if the country you are moving to has a tax agreement with the U.S., you may be exempt from paying taxes on your worldwide income. However, if you are moving to a country that does not have such an agreement with your home country, you may be required to pay taxes in both places. In some cases, this can lead to double taxation and result in higher taxes than what would have been due if you were only taxed once.
When in doubt about whether or not you have to file, consult an accountant or tax professional who is familiar with international taxes.
If you are a US resident Puerto Rico will be a good place to carry out this tax exemption plan. Puerto Rico has a policy of %100 tax exemption for capital gains. And this country could be cheaper than Dubai. But you still have to face some hurdles because one has to be a permanent resident to enjoy these exemption benefits. Purchasing a property in Puerto Rico might be the easiest means of becoming a bonafide residence. Depending on your location you kind find other countries that offer tax exemption policies based on the diplomatic relationship between your country and other nations.
