Speaking on the sidelines of his weekly public interaction programme, Kumar said Bihar was among the first states to have raised this demand at a GST Council meeting.
"We have always supported the GST and other measures that targeted black money holders. In fact, Bihar was among the first states to have raised such a demand," Kumar, flanked by deputy chief minister Sushil Modi, told reporters.
At a programme at Harvard University two days ago, Jaitley had said that real estate was one sector that has witnessed maximum tax evasion and cash generation.
"The one sector in India where maximum amount of tax evasion and cash generation takes place is real estate which is still outside the GST. Some of the states have been pressing for it. I personally believe that there is a strong case to bring real estate into the GST," Jaitley had said while delivering a lecture at the university.
