Multilateral Tax Treaties

Selected Multilateral Treaties

There are relatively few multilateral tax treaties compared to the much larger number of bilateral tax treaties.  The most important of multilateral tax treaties are described below.

Tools for Monitoring the Adoption of Multilateral Instrument Provisions by Individual Signatories

The following tools enable users to quickly determine whether a signatory to the OECD's Multilateral Instrument adopted (or opted out of) the provisions set forth in a particular article of the treaty and whether it did so subject to any reservations.

  • Multilateral Instrument Tool
    This Bloomberg Law tool can be used for a single jurisdiction or for multiple jurisdictions.
    • Begin by selecting one or more jurisdictions from the alphabetical list.  Then, under the heading Topics, check the box next to Status to determine if the jurisdictions selected have signed the MLI and, if so, which of the bilateral tax treaties for the selected jurisdictions are covered by the MLI.
    • Check the box next to List of Reservations and Notifications to determine if the jurisdictions previously selected have adopted an MLI article subject to any reservations.  To display only selected MLI articles, click on Expand Topics and then check the box next to the desired treaty article(s).
    • Be sure to select the Full Answer option in order to display complete information about each covered bilateral tax treaty and about each reservation.

  • MLI Country Monitor (available on the IBFD Tax Research Platform)
    • To access the tool, select Quick Reference Tables as the content type in the center of the homepage.  After the page refreshes, select the desired jurisdiction from the menu on the left.  After the page refreshes again, scroll through the list to find the MLI Country Monitor for the jurisdiction in question.
    • To generate a table comparing two or more jurisdictions, begin by clicking on the Tools tab.  After the page refreshes, click on Country Tables Comparison and select MLI Country Monitor from the menu on the left.  Then choose the desired jurisdictions.
