A transit subsidy was a payment of money that effectively lowered the cost of one's transportation.

In 2372, First Minister Shakaar Edon's adjutant Sarish Rez suggested that Shakaar mention his recent increase of transit subsidies to the crowd that was gathered on Deep Space 9's Promenade to see him. He also asked Shakaar to mention that, as a result of the subsidies, the cost to travel between Bajor and Deep Space 9 should begin to drop within a few months. (DS9: "Crossfire")
