ECONOMICS OF HARMFUL TAX COMPETITION 6-3<br />

a situation where <strong>the</strong> tax systems <strong>of</strong> a jurisdiction are designed <strong>in</strong> such a way that<br />

<strong>the</strong>y erode <strong>the</strong> tax bases <strong>of</strong> o<strong>the</strong>r jurisdictions <strong>and</strong> attract <strong>in</strong>vestments or sav<strong>in</strong>gs<br />

orig<strong>in</strong>at<strong>in</strong>g elsewhere, facilitat<strong>in</strong>g <strong>the</strong> avoidance <strong>of</strong> taxes <strong>in</strong> o<strong>the</strong>r jurisdictions.<br />

This def<strong>in</strong>ition emphasizes <strong>the</strong> adverse fiscal effect <strong>of</strong> HTC ra<strong>the</strong>r than displacement <strong>of</strong> real<br />

economic activity. Indeed, <strong>the</strong> clear reference to tax avoidance, taken literally, excludes <strong>the</strong><br />

impact <strong>of</strong> tax differentials on <strong>the</strong> physical location <strong>of</strong> substantive activity. 80<br />

Article 4.3 <strong>of</strong> <strong>the</strong> MOU goes on to say that Member States<br />

will, <strong>in</strong> <strong>the</strong> treatment <strong>and</strong> application <strong>of</strong> tax <strong>in</strong>centives, endeavor to avoid:<br />

(a) Harmful tax competition as may be evidenced by:<br />

(i) zero or low effective rates <strong>of</strong> tax;<br />

(ii) lack <strong>of</strong> transparency;<br />

(iii) lack <strong>of</strong> effective exchange <strong>of</strong> <strong>in</strong>formation<br />

(iv) restrict<strong>in</strong>g tax <strong>in</strong>centives to particular tax payers, usually non-<br />

residents;<br />

(v) promotion <strong>of</strong> tax <strong>in</strong>centives as vehicles for tax m<strong>in</strong>imization; or<br />

(vi) <strong>the</strong> absence <strong>of</strong> substantial activity <strong>in</strong> <strong>the</strong> jurisdiction to qualify for<br />

a tax <strong>in</strong>centive;<br />

(b) Introduc<strong>in</strong>g tax legislation that prejudices ano<strong>the</strong>r Member State’s economic<br />

policies, activities, or <strong>the</strong> regional mobility <strong>of</strong> goods, services, capital or labour.<br />

The conditions listed <strong>in</strong> section 4.3(a) as evidence for HTC <strong>in</strong>clude all five key factors cited by<br />

<strong>the</strong> OECD, plus one <strong>of</strong> <strong>the</strong> “additional characteristics” <strong>of</strong> a harmful tax regime: promotion as<br />

a vehicle for tax m<strong>in</strong>imization. Of <strong>the</strong> o<strong>the</strong>r seven OECD criteria, three may well be<br />

<strong>in</strong>appropriate for <strong>SADC</strong> countries because <strong>of</strong> adm<strong>in</strong>istrative constra<strong>in</strong>ts or special<br />

circumstances <strong>in</strong> low <strong>in</strong>come countries. 81 In pr<strong>in</strong>ciple, <strong>the</strong> rema<strong>in</strong><strong>in</strong>g four criteria—artificial<br />

def<strong>in</strong>ition <strong>of</strong> <strong>the</strong> tax base; negotiable tax rate or base; existence <strong>of</strong> secrecy provisions; <strong>and</strong><br />

encouragement <strong>of</strong> purely tax-driven operations—are just as applicable <strong>in</strong> <strong>the</strong> <strong>SADC</strong> region as<br />

<strong>the</strong>y would be elsewhere.<br />

Section 4.3(b) clearly perta<strong>in</strong>s to harmful effects <strong>of</strong> tax competition. Where tax <strong>in</strong>centives<br />

divert real capital <strong>in</strong>vestment from <strong>the</strong> location where productivity is highest, <strong>the</strong>y distort <strong>the</strong><br />

allocation <strong>of</strong> resources <strong>and</strong> reduce overall efficiency for <strong>the</strong> region. This <strong>in</strong>efficiency is a<br />

legitimate source <strong>of</strong> concern for <strong>SADC</strong>. But without a clear def<strong>in</strong>ition <strong>of</strong> “prejudice,” this<br />

provision is too broad to serve as an operational basis for action. One could argue that<br />

“prejudice” arises any time an <strong>in</strong>vestor chooses country A over country B, where A <strong>of</strong>fers<br />

more attractive tax rates (even if those rates are not unusually low). Until such time as <strong>the</strong><br />

80 If MegaCorp shifts production from country A to country B because <strong>of</strong> lower taxes, <strong>the</strong>n its <strong>in</strong>come falls<br />

under <strong>the</strong> jurisdiction <strong>of</strong> B. S<strong>in</strong>ce <strong>the</strong> taxable <strong>in</strong>come no longer arises <strong>in</strong> A, one cannot say that MegaCorp is<br />

engaged <strong>in</strong> avoidance <strong>of</strong> tax <strong>in</strong> A.<br />

81 The three po<strong>in</strong>ts are <strong>in</strong>ternational transfer pric<strong>in</strong>g pr<strong>in</strong>ciples; exempt<strong>in</strong>g foreign source <strong>in</strong>come; <strong>and</strong> wide<br />

network <strong>of</strong> tax treaties.
