The German giants will pay Barca €8.5m, with an option to buy the mercurial playmaker for €120m also inserted into the deal.
It's a destination few saw Coutinho ending up at this summer, but it could be one that revives the Brazilian's career after a woeful 2018/19 season in Catalonia.
Barca fans turned on him, he rarely completed 90 minutes and he simply looked a shadow of the player who dazzled at Liverpool.
At Bayern, he will be hoping he can showcase his skillset at one of the biggest teams in world football after being handed the club's famous number 10 shirt - previously donned by Arjen Robben.

With that in mind, we've provided three different ways Bayern could lineup after adding Coutinho to their star-studded squad.
1. Coutinho as the new Franck Ribery
A right-footed attacker who loves playing from the left? Exactly what Bayern need to replace Ribery.
Ivan Perisic has also been brought in to offer cover on the flanks, but the Croatian offers a different threat to both Ribery and Coutinho.
If Kovac wants to replicate the threat of the legendary Frenchman, Coutinho may be his safest bet, with Serge Gnabry wreaking havoc on the opposite wing.
2. The perfect foil for Robert Lewandowski
Bayern's attack is geared to supply Lewandowski and in Coutinho, they have the perfect player to get close to and work in tandem with the Polish striker.
With the likes of Perisic, Gnabry or Kingsley Coman out wide, the Brazilian would operate as the central playmaker of the team, with the metronomic Thiago and the more defensive Javi Martinez behind.
It would mean the likes of Thomas Muller and Leon Goretzka having to make do with spots on the bench, though - which would be an extremely bold call to make on a regular basis.
3. A deep-lying playmaker
Very similar to the above formation, but this time Coutinho would sit slightly deeper in a midfield three, as he regularly does for Brazil.
Leon Goretzka takes the place of Martinez, with Thiago the man at the base of the trio.
The attacking threat from midfield alone would be pretty scary and it would likely blow inferior opposition away.
Martinez or Corentin Tolisso could come in for Goretzka to add more of a pragmatic edge to the trio in games against high calibre opposition.News Now - Sport News
