Set a target of 262 for victory, J&K went past the score riding on the match winning eighth-wicket partnership after they found themselves in a spot of bother with seven down for 148 on the fourth and final day here.
Earlier in the day, Goa's final batting pair of Amit Yadav (41 not out) and Gauresh Gawas (0) could add only a run to their overnight score of 245 for nine at the Sher-i-Kashmir Stadium.
Skipper Pervez Rasool (39) and Manzoor Dar (37) looked to steady the ship with a 63-run partnership for the fourth wicket. But Goa spinners Shadab Jakati (2/96) and Amit Yadav (2/71) made further inroads into the J&K batting, raising hopes of their side's first win of the season.
However, the pair of Singh and Beigh took the game away from Goa with their gritty knocks to give the hosts full six points from their second match of the tournament.
For Goa, besides Jakati and Yadav, pacers Harshard Gadekar (2/32) and Saurabh Bandekar (1/23) were the other successful bowlers.
Brief Scores:
Goa: 317 & 246 all out (Keenan Vaz 59, Ravikant Shukla 46; Parvez Rasool 4/65).
J&K: 302 & 262/7 (Hardeep Singh 95 not out, Samiullah Beigh 50 not out; Harshard Gadekar 2/32).
Points: Jammu & Kashmir 6, Goa 0.
