"The toll is now at 27 dead and 24 injured -- they are severely injured from what I can see," police captain Sittichai Panyasong of Mae Tho district in Tak province said, revising up an earlier toll.
The accident took place at around 8:40 pm local time (1340 GMT) in Tak, which borders Myanmar.
A local hospital confirmed the number of dead at 27, adding most died at the scene.
"The brakes failed as the bus came downhill on a hilly road and it crashed through the concrete barrier and fell into 150 metre-deep ravine," Sittichai added.
The victims are all believed to be Thai local government officials on a work trip to neighbouring provinces, he said.
Thailand's roads are among the world's deadliest and accidents are common, especially on buses travelling late at night.
A recent report by the World Health Organization said Thailand saw some 38.1 road deaths per 100,000 people in 2010 -- behind only the Dominican Republic in the Caribbean and the South Pacific island of Niue.
That compares with an average of 18.5 in Southeast Asia as a whole.
