"Technically, we have decided to have a pre-poll tie-up with GSM. But the formal alliance with a seat-sharing formula would be announced on coming Sunday," MGP president Dipak Dhavalikar told PTI.
MGP and GSM have held a series of meetings to formalise allocation of seats for the February 4 polls.
Goa has total 40 seats spread across South Goa and North Goa districts.
MGP was Goa's first ruling party after the end of Portuguese colonial rule in 1961. It had contested 2012 polls in alliance with the BJP.

Of late, chasm between MGP and BJP grew as the former was unhappy with the leadership of incumbent chief minister Laxmikant Parsekar and had openly criticised him.
The simmering differences culminated into Parsekar sacking MGP stalwarts Dipak Dhavlikar and Sudin Dhavlikar from his cabinet last month.
Velingkar had floated Goa Suraksha Manch after he was removed from the post of Goa RSS chief last year, following his public criticism of the BJP's policies like Medium of Instruction (MoI) and continuation of grants to English medium schools. He had announced to contest against BJP, earning him the sack from RSS.
GSM has already announced its alliance with Shiv Sena, the alliance partner of the BJP in Maharashtra and central governments.
