8-4 EFFECTIVENESS AND IMPACT OF TAX INCENTIVES IN THE <strong>SADC</strong> REGION<br />

Countries fac<strong>in</strong>g serious revenue constra<strong>in</strong>ts should be especially cautious about <strong>of</strong>fer<strong>in</strong>g<br />

<strong>in</strong>centives that create substantial revenue risks, ei<strong>the</strong>r directly or <strong>in</strong>directly. This pr<strong>in</strong>ciple is<br />

important not only to ma<strong>in</strong>ta<strong>in</strong> macroeconomic stability, but also to prevent tax <strong>in</strong>centives<br />

from undercutt<strong>in</strong>g <strong>the</strong> state’s fiscal capacity to improve more basic elements <strong>of</strong> <strong>the</strong> <strong>in</strong>vestment<br />

climate.<br />

To ensure proper consideration <strong>of</strong> revenue objectives, <strong>the</strong> m<strong>in</strong>istry responsible for f<strong>in</strong>ance<br />

must be centrally <strong>in</strong>volved <strong>in</strong> formulat<strong>in</strong>g tax <strong>in</strong>centive policies. Fur<strong>the</strong>rmore, to preclude<br />

legal <strong>in</strong>consistencies, tax <strong>in</strong>centives should be <strong>in</strong>corporated <strong>in</strong> or carefully coord<strong>in</strong>ated with<br />

<strong>the</strong> relevant tax legislation. Ano<strong>the</strong>r m<strong>in</strong>istry or agency may have <strong>the</strong> authority to manage<br />

<strong>and</strong> adm<strong>in</strong>ister <strong>the</strong> tax <strong>in</strong>centive program, but <strong>the</strong> f<strong>in</strong>ance m<strong>in</strong>istry must control <strong>the</strong><br />

budgetary consequences. One way to shift authority while reta<strong>in</strong><strong>in</strong>g fiscal control is to set an<br />

explicit budgetary ceil<strong>in</strong>g on <strong>the</strong> amount <strong>of</strong> tax breaks that can be granted <strong>in</strong> any fiscal year.<br />

CHOICE OF TAX INCENTIVE INSTRUMENTS<br />

The advantages <strong>and</strong> disadvantages <strong>of</strong> each tax <strong>in</strong>centive <strong>in</strong>strument must be judged <strong>in</strong> light <strong>of</strong><br />

local conditions <strong>and</strong> priorities, subject to systematic policy analysis to support well <strong>in</strong>formed<br />

decisions. Never<strong>the</strong>less, our analysis suggests ten broad conclusions about <strong>the</strong> choice among<br />

tax <strong>in</strong>centive <strong>in</strong>struments:<br />

1. The soundest tax <strong>in</strong>centive, overall, is to establish st<strong>and</strong>ard tax rates that are fair <strong>and</strong><br />

moderate <strong>in</strong> comparison with rates prevail<strong>in</strong>g elsewhere <strong>in</strong> <strong>the</strong> region <strong>and</strong> <strong>in</strong> <strong>the</strong> ma<strong>in</strong><br />

capital-source countries.<br />

2. Reliev<strong>in</strong>g exporters <strong>of</strong> <strong>in</strong>direct tax on <strong>the</strong>ir <strong>in</strong>puts should be a top priority, with due<br />

regard to <strong>the</strong> need for effective procedures to prevent abuse <strong>of</strong> tax <strong>and</strong> duty remissions.<br />

3. The most cost-effective tax <strong>in</strong>centives are <strong>the</strong> <strong>in</strong>vestment tax credit (ITC) <strong>and</strong> <strong>the</strong> <strong>in</strong>itial<br />

capital allowance. These tools yield a large reduction <strong>in</strong> <strong>the</strong> marg<strong>in</strong>al effective tax rate<br />

(METR) relative to <strong>the</strong> revenue cost, with a m<strong>in</strong>imum <strong>of</strong> adm<strong>in</strong>istrative complexity.<br />

However, <strong>the</strong>se <strong>in</strong>centives are not costless. They create moderate distortions by favor<strong>in</strong>g<br />

capital-<strong>in</strong>tensive projects <strong>and</strong> short-lived assets, <strong>and</strong> <strong>the</strong>y can serve as avenues for tax<br />

evasion if not well adm<strong>in</strong>istered.<br />

4. <strong>Tax</strong> holidays with a full exemption are far less cost-effective. The revenue loss is large<br />

relative to <strong>the</strong> improvement <strong>in</strong> <strong>in</strong>vestment <strong>in</strong>centives via reduction <strong>of</strong> <strong>the</strong> METR. <strong>Tax</strong><br />

holidays also favor transitory ra<strong>the</strong>r than susta<strong>in</strong>able <strong>in</strong>vestments, <strong>and</strong> <strong>the</strong>y create glar<strong>in</strong>g<br />

opportunities for aggressive tax avoidance.
