Commerce and industry minister Anand Sharma on Sunday said that investors need clarity on tax laws and once the goods and services tax (GST) and the direct taxes code (DTC) are rolled out the rough edges will be ironed out through a stable regime.

"The government is working on it and GST is being pushed with all sincerity," he said.

The industry's concerns over key issues, including levying a minimum alternate tax (MAT) on special economic zones (SEZs), will be addressed once GST and DTC are implemented.
