Diurnal and arboreal, the black-tufted marmoset has a lifestyle very similar to other marmosets.
It typically lives in family groups of 2 to 14.
The groups usually consist of a reproductive couple and their offspring.
Twins are very common among this species and the males, as well as juvenile offspring, often assist the female in the raising of the young.

Though the black-tufted marmoset lives in small family groups, it is believed that they share their food source, sap trees, with other marmoset groups.
Scent marking does occur within these groups, but it is believed that the marking is to deter other species rather than other black-tufted marmoset groups, because other groups typically ignore these markings.
They also appear to be migratory, often moving in relation to the wet or dry seasons, however, the extent of their migration is unknown.

Though communication between black-tufted marmosets has not been studied thoroughly, it is believed that it communicates through vocalizations.
It has known predator-specific cries and appears to vocalize frequently outside of predator cries.
