"A proposal in this regard has come from JVM, which will formally merge with BJP," Munda said at a function after another party Jharkhand Disom Party (JDP) merged with the BJP.
The merger will take place on August 20, a day before Prime Minister Narendra Modi's visit to Jharkhand.
Munda however, refused to divulge details of the merger when asked whether JVM supremo-cum-former Jharkhand Chief Minister Babulal Marandi would return to BJP.
Four JVM legislatures joined BJP at a function held in Ranchi recently.

Jharkhand Disom Party merges with BJP
Jharkhand Disom Party (JDP) formally merged with the BJP in presence of former Jharkhand Chief Minister Arjun Munda on Monday.
Announcing the merger, Munda said a strong wave in favour of BJP was sweeping across the country and a host of political leaders irrespective of their party affiliations have expressed their willingness to join or return to the party fold.
"Prime Minister Narendra Modi was accepted by the people for his emphasis on 'Sabka Saath, Sabka Vikas' campaign after he assumed the office of Prime Minister," Munda said.
"The people of mineral-rich Jharkhand are expecting a similar change in the next Assembly elections as BJP can provide a strong government instead of a helpless one for political stability and rapid development with the involvement of people from all sections of the society," he said.
On JDP's merger, Munda said negotiations were on in this regard for some time and the issue was finalised after a discussion with former BJP MP and JDP president Salkhan Murmu.
It was the A B Vajpayee-led NDA government, which had understood the aspirations of the people of Jharkhand and created a separate state to fulfil their dreams, he said adding Jharkhand has the potential to lead the country.
Oozing confidence that BJP would form a government on its own in the next Assembly elections, Munda said some regional political parties have lost their credibility and have started disintegrating.
On the merger, Salkhan Murmu said the decision came forth not because of any compulsion, disappointment or greed, but the JDP had changed its political strategy only to achieve its goals under the BJP's banner.
