Christians and Ezenagu: Kill Switches in the New US Tax Treaty

Recently published as part of the Brooklyn Law School symposium Reconsidering the Tax Treaty, this article looks at the introduction of new clauses to switch off treaty benefits where the treaty partner adopts certain kinds of tax rate or base reductions.  I think these clauses are interesting because they create a way for one country to control the future tax policy decisions of another. Whether other countries will agree to a treaty with such a provision is another story.

Here is the abstract:
The new US model income tax treaty contains an unusual addition: mechanisms for the parties to unilaterally override the negotiated treaty rates in specified circumstances. Previewed last year in proposed form — a first for Treasury — these new mechanisms work as kill-switches, partially terminating the treaty as to one or both treaty partners. The idea is to forestall a more problematic outcome, such as an enduring breach of one of the parties’ expectations, or the opposite, a complete termination of all the treaty terms in the face of such a breach. Yet embedding a kill-switch in a treaty creates distinct legal, procedural, and political pressures in the tax-treaty relationship that implicate treaty negotiation, ratification, interpretation, and dispute resolution. Kill-switches also communicate a defensive tenor in the tax treaty relationships among many countries. This Article analyzes the new kill-switch provisions and concludes that their introduction in the U.S. Model reflects the steady deterioration of tax treaties from essentially diplomatic documents premised on the good faith of the parties to detailed contracts drafted in anticipation of the opposite.
