The Social Movement for Advocacy, Rights and Transformation, SMART is pressing SARS to crack down on widespread tax evasion in the spaza shop sector following damning findings by the Public Protector. The group says many outlets allegedly run by undocumented foreign nationals operate unlicensed, dodging taxes while using public services and infrastructure. SMART says this lost revenue is hurting South Africa's strained fiscus at a time of mounting debt and service delivery pressures. The organisation urges closer collaboration between SARS, Home Affairs, municipalities and other agencies to register compliant businesses and enforce the law fairly, without targeting nationality. We spoke to SMART Manager for Advocacy And Communication, Lehlogonolo Muthevhuli.
