Joining the BJP in the presence of Haryana Chief Minister Manohar Lal Khattar and party general secretary in charge of the state Anil Jain, Sharma hailed the Modi government, saying all sections, especially the poor, of the society have progressed under it.
Khattar and Jain said Sharma's induction into the party would strengthen it.
He had lost to the BJP's Ashwini Chopra in 2014. Chopra has been critical of the BJP leadership for some time and is unlikely to be fielded by it in the general election slated for April-May.
The BJP has relied on the support of non-Jat communities in the state in elections and hopes that Sharma's induction will boost its prospects.
