Special economic zones (SEZs) are widely used to attract investment, promote exports, and support industrialization, yet their performance is uneven and often uncertain. This How To Note reviews global experience with SEZs\u2014their rapid expansion, diverse design, and mixed economic impact\u2014and highlights that many operate as enclaves with limited spillovers and high fiscal costs. While generous tax incentives are common, evidence suggests they are rarely decisive drivers of investment and can lead to significant revenue losses, distortions, and opportunities for profit shifting. The note provides practical guidance for policymakers on how to design and tax SEZs effectively.<\/p>\n\n\n\n
It emphasizes that taxation should generally remain neutral relative to the domestic economy, with any incentives closely aligned to clear policy objectives, time-bound, and subject to regular evaluation. Priority should be given to well-designed indirect tax regimes and to cost-based investment incentives rather than profit-based tax holidays.<\/p>\n\n\n\n
Ultimately, the success of SEZs depends far more on fundamentals\u2014such as infrastructure, governance, regulatory efficiency, and integration with the domestic economy\u2014than on tax breaks alone.<\/p>\n\n\n\n
