Introduction to the South African Revenue Service and National Treasury firm-level panel
The South African Revenue Service and National Treasury Firm-Level Panel is an unbalanced panel data set created by merging several sources of administrative tax data received during 2015.
The four data sources that constitute the panel are:
- company income tax from registered firms who submit tax forms;
- employee data from employee income tax certificates submitted by employers;
- value-added tax data from registered firms; and
- customs records from traders.
These data sets constitute a significant and unique source for the study of firm-level behaviour in post-apartheid South Africa.
We review the key data sources used to construct the panel, highlight some important questions that arise as a result of panel construction, discuss the biases in the resulting data, compare key aggregates in the panel to other data sources, and provide a descriptive overview of the tax records.
