Tax treaty in the context of "Double taxation"

The arm's length principle (ALP) is the condition or the fact that the parties of a transaction are independent and on an equal footing. Such a transaction is known as an "arm's-length transaction". It is used specifically in contract law to arrange an agreement that will stand up to legal scrutiny, even though the parties may have shared interests (e.g., employer-employee) or are too closely related to be seen as completely independent (e.g., the parties have familial ties).

An arm's length relationship is distinguished from a fiduciary relationship, where the parties are not on an equal footing, but rather, power and information asymmetries exist. It is also one of the key elements in international taxation as it allows an adequate allocation of profit taxation rights among countries that conclude double tax conventions, through transfer pricing, among each other. Transfer pricing and the arm's length principle were one of the focal points of the base erosion and profit shifting (BEPS) model developed by the OECD and endorsed by the G20.

Corporate haven, corporate tax haven, or multinational tax haven is used to describe a jurisdiction that multinational corporations find attractive for establishing subsidiaries or incorporation of regional or main company headquarters, mostly due to favourable tax regimes (not just the headline tax rate), and/or favourable secrecy laws (such as the avoidance of regulations or disclosure of tax schemes), and/or favourable regulatory regimes (such as weak data-protection or employment laws).

Unlike traditional tax havens, modern corporate tax havens reject they have anything to do with near-zero effective tax rates, due to their need to encourage jurisdictions to enter into bilateral tax treaties that accept the haven's base erosion and profit shifting (BEPS) tools. CORPNET show each corporate tax haven is strongly connected with specific traditional tax havens (via additional BEPS tool "backdoors" like the double Irish, the Dutch sandwich, and single malt). Corporate tax havens promote themselves as "knowledge economies", and intellectual property (IP) as a "new economy" asset, rather than a tax management tool, which is encoded into their statute books as their primary BEPS tool. This perceived respectability encourages corporates to use these International Financial Centres (IFCs) as regional headquarters (i.e. Google, Apple, and Facebook use Ireland in EMEA over Luxembourg, and Singapore in APAC over Hong Kong/Taiwan).
