Recently, Macau resident Zhang Tao logged into the "Electronic Taxation Bureau" of the Hengqin Guangdong Macao Deep Cooperation Zone and processed both Macau Central Provident Fund contributions (Macau social security public service matters) and mainland individual social security contributions, marking the first time that social security services in Guangdong and Macau have achieved cross-border one-stop processing. "I work in Macau and reside in mainland China. It was my first time trying to apply for social security services online in Guangdong and Macau, and I didn't expect it to be so convenient. Whether in mainland China or Macau, as long as there is internet access, I can handle it, greatly improving the experience and efficiency of cross-border livelihood services," said Zhang Tao. It is reported that there are over 60000 Macau residents like Zhang Tao who are insured in mainland China. The Taxation Bureau of the Hengqin Guangdong Macao Deep Cooperation Zone of the State Administration of Taxation has added entry points for the processing of social security services in Macau using the new "Electronic Taxation Bureau" currently being promoted nationwide. During the Tax Promotion Month, it has carried out precise publicity for Macau residents living and working in Hengqin. The insured can click on the "Macau Social Security Business" module to navigate to the Macau Social Security Fund processing portal, achieving automatic switching of online transactions. It is reported that since the establishment of the Hengqin Guangdong Macao Deep Cooperation Zone, it has continuously strengthened cooperation with Macau's social and livelihood, and promoted the orderly connection of public services and social security systems with Macau. This time, we have achieved cross-border "one network access" for social security services, further forming a Guangdong Macao social security service system with online and offline interaction and three-dimensional integration, bringing residents of Guangdong and Macao a better and more convenient experience of livelihood services. Next, the Hengqin Taxation Bureau will further deepen the reform of tax collection and management, and continuously improve the level of cross-border tax and fee services. (Lai Xin She)
