Tension between prominent malls and their star tenant Zara are mounting. After malls were irked by the Spanish fashion retailer promoting its online platform in stores, the latest wrangle between them is over a change brought about by the introduction of goods and services tax. High Street Phoenix in Mumbai and the National Capital Region’s Mall of India, Select Citywalk, Promenade and Pacific, among other shopping centres, are refusing to continue with a “special arrangement” where they used to pay half of the 15 per cent service tax on rent paid by Zara.
