Leicester City have recorded pre-tax profits of £16.4m for their 2015-16 title-winning campaign, a drop of £10m on the previous year.
It has also been confirmed that the Football League have not accepted Leicester's Financial Fair Play return for the 2013-14 season as "compliant".
The Foxes' turnover in their Premier League-winning season rose to £24m, mainly based on prize money, while they also increased their income through having more games televised and returned a £10.8m transfer profit.
The club donated £2m towards the development of a new Leicester Children's Hospital and invested a further £3.5m into its fixed asset infrastructure.
Leicester City chief executive Susan Whelan said: "The 2015/16 season will be remembered for generations to come as the season Leicester City changed the game.
"But those closest to our success - our supporters - will know that, while unexpected, it was a reward for the years of sustainable planning that preceded it."
Meanwhile, further details have emerged regarding Leicester's ongoing row with the Football League concerning their 2013/14 promotion season, and the club has now challenged the legality of the 2012 Championship FFP regulations as they believe them to be unlawful.
Leicester faced severe criticism in their promotion year from the Championship, with accusations that they had artificially boosted income through a shirt-sponsorship deal with King Power - the company owned by club owners, the Srivaddhanaprabha family.
