As the rally disperses peacefully at 4.30pm, an estimated 50,000 is reported to have gathered around the streets of Dataran Merdeka in today's May Day rally against the Goods and Services Tax (GST). A goods and services tax in Malaysia (GST), a value added tax, was scheduled to be implemented by the government during the third quarter of 2011, but has not yet been implemented. Its purpose is to replace the sales and service tax which has been used in the country for several decades. The government is seeking additional revenue to offset its budget deficit and reduce its dependence on revenue from Petronas, Malaysia's state-owned oil company. The four-percent tax will replace a sales-and-service tax of between five and ten percent. The government responded by asserting that the tax on oil income will not be sustainable in the future. Muslim Consumer Association of Malaysia leader Datuk Dr. Ma’amor Osman said the GST could help end dishonest business practices, but expressed concern about how the tax would be applied to medical products and services. A group leading the campaign against the GST objects to the GST because of concerns about its effects on low-income Malaysians. During the government reading of the 2014 budget, Malaysian Prime Minister Najib Razak announced a GST tax of six percent starting on April 1, 2015. This will replace the Sales and Services Tax.
