The disparity in earnings is most notable when compared to other high-profile arrivals in the league, such as Son Heung-min. The former Tottenham winger, who joined LAFC in a landmark move for the Western Conference side, earns significantly less than the man in South Florida - who is now pulling in $28.3 million (£21m).
Official records indicate that Messi is currently earning more than twice the amount of the South Korea international.
Son remains one of the premier talents in the league and a vital component of the Los Angeles side's attacking threat, yet his compensation highlights the "Messi Exception" that exists within the MLS salary cap structure.
While Son is among the top five earners in the league, he still trails Messi's total guaranteed compensation when earning $11.1m (£8m) from his own deal.
