What Is the Main Purpose Test?
Main Purpose Test refers to an anti-abuse standard denying a tax advantage when securing the advantage was a main purpose of an arrangement.
Also known as: Main Purpose Rule, One of the Main Purposes Test.
How Main Purpose Test works
Main Purpose Test is an anti-abuse condition found in domestic tax legislation, EU directives and some treaty provisions, which asks whether obtaining a tax advantage was the main purpose, or one of the main purposes, of a transaction or arrangement, and which removes the advantage when the answer is yes. The EU Anti-Tax Avoidance Directive, for example, requires Member States to ignore arrangements put in place for the main purpose or one of the main purposes of obtaining a tax advantage which defeats the object or purpose of the applicable tax law and which are not genuine. An arrangement is non-genuine where valid commercial reasons reflecting economic reality are absent. Outcomes depend on all facts and circumstances and on how each jurisdiction words its test.
Main Purpose Test vs Principal Purpose Test
Unlike the Principal Purpose Test, the treaty clause introduced through the OECD BEPS project, Main Purpose Test is a broader label for purpose-based anti-abuse wording in domestic statutes, EU directives and individual tax provisions.
Example
Illustrative example: A consultant moves an existing client contract into a newly formed company in Country A to access a lower corporate rate, with no staff or premises. A main purpose test in Country A's law may allow the tax authority to disregard the arrangement and tax the income as if the contract had remained personal.
Common misconception
Myth: Any arrangement with some commercial reason automatically passes a main purpose test.
Reality: A Main Purpose Test can apply where a tax advantage was one of the main purposes even when commercial reasons also exist, depending on the wording of the specific provision.
