Abstract:This paper conducts a rigorous analysis of the impact of social security taxation on tax compliance, taking advantage of taxation variations across both cities and occupations that are created by China’s specific social security system. This system has some salient features including that the statutory contribution rate is high, local governments have the discretion to set the local social security contribution rates, the system is two-tiered, and the rate of return to social security is low and uncertain. We use the 2002-2006 data from the annual China Urban Household Survey and employ both the pooled cross-sectional and panel data sets. We find that higher statutory contribution rate causes lower possibility of participation in social security programs and smaller percentage of taxable salary in total labor compensation. In particular, a 10 percentage-point increase in statutory contribution rate reduces the possibility of participation by 3 to 4 percentage points and reduces the percentage of taxable salary by 3 to 7 percentage points depending on specification. Moreover, individuals who are more likely to move to public sectors have even lower percentage of taxable salary, but their participation is not differentially affected. In summary, the distortion comes from both the high statutory contribution rate and the nature of the two-tiered social security system.
