Further tax hikes will not be helpful in raising revenue, as intended, the Financial Fiscal Commission warned. The commission, which is a constitutional body that advises all organs of state on economic, financial and fiscal matters, on Tuesday briefed Parliament’s committees in finance and appropriations on its analysis on the medium-term budget policy statement. The policy statement was tabled in Parliament last week by Finance Minister Tito Mboweni. Treasury projects a revenue shortfall of R53-billion and national debt is expected to breach 70% of GDP by 2022/23. Treasury said it was considering additional tax measures to boost tax revenue.
