According to reports, the Celtic defender will leave the Scottish Premiership champions on a free transfer at the end of the season to join the German outfit.
The Scottish Sun report that the Belgium international is to make around £2 million per year by joining Hertha, where he will subsequently become one of the club's highest earners alongside Ivory Coast international Salomon Kalou.
Boyata is set to earn around £40,000 per week in Germany.
The former Manchester City defender came close to leaving Celtic Park last season with the same report suggesting that Hertha were willing to pay around £4.5 million to land the 28-year-old at the time.
Boyata was eager to force through a move, but ultimately remained in Scotland for the 2018-19 season.
Injury, though, has plagued his season and Boyata is currently nursing a knee injury that will keep him sidelined until mid-July.
In total, Boyata has scored 15 goals in 135 appearances for Celtic.
