The bill, signed by the President Thein Sein on Friday, requires that demonstrators inform the authorities five days in advance of when, where and why they wish to protest, according to the official Myanmar Ahlin newspaper.
The law was passed last month by a parliament dominated by Thein Sein`s party and its military allies, making his final approval a mere formality.
It requires would-be protesters to tell the authorities in advance what they will talk or chant about at their gathering, as well as the route they plan to take.
It is forbidden to block traffic or cause disturbances during rallies.
Anybody who protests without permission risks one year in jail, while disturbing a peaceful gathering carries a penalty of two years` imprisonment.
Protests are rare in the authoritarian country formerly known as Burma, where pro-democracy rallies in 1988 and 2007 were brutally crushed by the junta.
Myanmar`s new parliament opened in January after nearly five decades of outright military rule following an election in November -- the first in 20 years -- that was dismissed by many observers as a sham.
The new leaders of the country, which is subject to Western sanctions, have surprised observers with a number of reformist steps in an apparent move to end international isolation, and welcomed US Secretary of State Hillary Clinton on a landmark three-day visit which wrapped up on Friday.
On the same day, Myanmar authorities reached a ceasefire deal with one of the war-torn country`s major ethnic guerrilla groups, the Shan State Army South, a mediator involved in the talks said. (*)
