The government statistics office said the economy shrank 0.9 per cent in the last three months of 2016. That meant an overall dip of 3.6 per cent in 2016, following a 3.8 per cent fall in 2015.
This is the deepest decline since records began.
Brazil has been shaken by a slump in prices for its oil, soy, metals and other commodity exports, as well as political instability and a huge corruption scandal.
The political leadership has been in crisis since last year when president Dilma Rousseff was impeached for illegally manipulating government accounts, while several high ranking allies of her successor President Michel Temer are now mired in a sprawling graft probe.
The embezzlement and bribery scandal -- which is due to pick up pace soon with the expected release of damaging testimony against senior political figures -- is slowing down Temer's attempt to pass economic reforms in Congress.
