In 2012, gross tax revenue is expected to be R5 billion (from R826.401 billion in February 2012 to R821.401 billion during the MTBPS tabling) less than the February 2012 estimate. It still implies a robust nominal growth rate of 10.6 per cent over the previous year. This nominal growth in tax revenue was attributed to steady improvements in compliance of South African tax payers while the continued weakness in the domestic economic environment led to revised estimates. BUSA is concerned about alternative revenue options in an event that the economy fails to recover as projected.
