Abstract
This policy brief reflects on an underexplored proposition: that bilateral tax treaties – particularly
treaties involving (middle- and) low-income countries – should contain an expiration or sunset clause.
The brief examines some reasons why it may be sensible for a low-income country to make its bilateral
tax treaty expirable, from its onset. It also highlights a few reasons why such a policy may not be
advisable – or tenable. The brief concludes by exploring the design of a model sunset clause for
inclusion in the UN Model Tax Convention.
