In a letter to Jaitley, Sisodia said if real estate comes under the new indirect tax regime, exorbitant hike in land prices could be checked and the flow of black money curbed.
Sisodia, who also holds the finance portfolio, said he had no hesitation in stating that "extraordinary political willpower will be required for taking this step".
The minister has demanded that the matter of bringing the real estate sector under the GST regime be included in the agenda for the next GST Council meeting to be held at Guwahati on November 9.
He hoped that the GST Council was in a position to take a call on the real estate sector in its next meeting.
Since the implementation of GST in July, the Delhi deputy chief minister has been demanding that real estate be brought under it.
