The sub-group was formed in March this year and Madhya Pradesh Chief Minister Shivraj Singh Chouhan is its convener.
NITI Aayog Chief Executive Officer (CEO) Sindhushree Khullar is the coordinator of the sub-group.
"The NITI Aayog sub-group on centrally sponsored schemes (CSS) will submit its final report to the Prime Minister tomorrow," sources said.
Chief Ministers of Rajasthan, Uttar Pradesh, Kerala, Jharkhand, Arunachal Pradesh, Jammu & Kashmir, Manipur, Nagaland, Telangana, and Lt Governor of Andaman & Nicobar Islands are among the members of the panel.
Earlier in June, the sub-group had reached a consensus in favour of reducing the number of CSS to 30 from present 72.
Besides, the panel also recommended increasing the share of flexi funds to 25 per cent from the current 10 per cent towards the schemes.
