Barbados has thirty-four treaties in place, including a multi-jurisdictional treaty with fellow members of the CARICOM (Caribbean Common Market) area.
Double taxation agreements set out the rules between trading partners to avoid taxable income earned in one jurisdiction between taxed in two or more jurisdictions. Double taxation may be mitigated as follows:
- Exempting foreign source income earned in another territory
- Exemption of foreign source income that is taxed in another jurisdiction which is not considered a tax haven
- The taxation of foreign source income by one tax jurisdiction allows a credit for taxes paid in the other jurisdiction where the foreign source income was earned.
