In total, the Chicago 2016 Bid Committee raised $75.9 million (£53.1 million) during its 42-month campaign to bring the Summer Games to the United States for the first time since Atlanta in 1996.
A sum of $16.5 million (£11.5 million) of that figure, including $6 million (£4 million) left over, was donated to World Sport Chicago, a not-for-profit that promotes youth sports programmes, as a legacy of the effort.
The final tally includes money raised through cash contributions, event revenues, merchandise sales and interest income.
The bid also received $16.2 million (£11.3 million) in donated goods and services, bringing total resources to $92.1 million (£64.4 million).
A tax filing revealed that last year Chicago spent $1.2 million (£840,000) on a public relations campaign run by Hill & Knowlton with a further $1.2 million (£840,000) on its website, run by Ogilvy & Mather.
Other contractors who received notable sums were DeMarsh Construction, paid $452,000 (£316,310) for construction consulting services, and RSA Films, paid $407,000 (£284,419) for film production.
Chicago also spent $736,025 (£515,070) to lobby European sports federations and International Olympic Committee (IOC) members.
The tax return also reveals that Chicago spent $5.9 million (£4.1 million) on wages and benefits in 2009, including more than $500,000 (£348,750) in bonuses, even though the city was the first of the four bidders to be eliminated in the vote at the IOC Session in Copenhagen last year.
David Bolger, a former Aon Corp. executive who was chief operating officer of Chicago 2016, received a $200,000 (£139,500) retention bonus on top of his $283,713 (£1978,889) salary, according to the filing.
Bolger, however, did take a salary cut from his original $300,000 (£209,250) base salary as the economy worsened.
Doug Arnot, the former chief executive of USA Rugby, who served as Chicago's director of sport, received a $125,000 (£87,187) bonus in addition to his $248,013 (£172,989) salary.
Arnot is now working for London 2012 as director of Games operations.
John Murray, a former McKinsey consultant who served as chief bid officer, received a $125,000 (£87,187) bonus on top of his $239,482 (£167,039) salary.
Valerie Waller, a marketing executive, received a $25,000 (£17,438) bonus on top of her $185,894 (£129,661) salary.
Patricia Rios, who handled administration, received a $13,000 (£9,068) bonus in addition to her $126,613 (£88,312) salary.
Richard Ludwig, chief financial officer, received a $100,000 (£69,750) bonus on top of his $242,158 (£168,905) salary.
Aon founder Patrick Ryan, who was chairman and CEO of the bid committee, chose not to receive any payment.
Ryan said: "Although unsuccessful in our attempt to bring the 2016 Games to Chicago, we believe the bid showcased the greatness of our city and its citizens to the world, and inspired tens of thousands of Chicago youth to become engaged in sport,"
