Axelasia Inc Group chairman Veerinderjeet Singh said there would be a need for annual assessments similar to what was done after the implementation of the good and services tax (GST).

“A two-year time frame would give you an idea of where things went wrong or where it can be improved, whether the revenue is really coming in at the level you expected or if it fell below expectations.”

He said the evaluation could be based on its collection target and effectiveness.

Veerinderjeet said a two-year time frame was sufficient as the SST had been implemented before, instead of the three-year time frame set by the World Bank to see if the system had stabilised.

“It is enough to see whether you should look at other options,” he told a press conference after the SST2.0 Seminar here today.
