Newspaper Bild said players and club officials at champions Bayern, top of the Bundesliga when the season was halted on March 13, have accepted a 20 percent cut in their salaries.
Like all top European leagues, the German top flight is losing income from broadcasting, sponsorships and ticket sales during the COVID-19 pandemic, with matches in Germany suspended until at least April 30.
Bayern have a massive wage bill which reached 336 million euros ($364 million) last year, almost half of club turnover.
Players at Borussia Moenchengladbach were the first in the Bundesliga to propose a pay cut, followed by others at Werder Bremen, Schalke 04 and Borussia Dortmund. Bayer Leverkusen players are in talks over pay cut proposals with management.
Second-placed Dortmund said their squad members had taken a salary reduction to show solidarity with the club's 850 employees.
Coach Lucien Favre and club directors have also made a personal offer to take a pay cut.
