After some of the world's biggest corporations such as Apple and Google have come under pressure over aggressive tax avoidance strategies, now its FIFA's turn to defend its lucrative financial arrangements with 2014 World Cup hosts Brazil.
The relationship of football's world governing body with Brazil is under scrutiny following the protests that have gripped the country as the South American country stages June's Confederation Cup -- a test run for the main event next year.
Initially disgruntlement of the protesters centered on a 20 centavos (10 cents) rise in bus and train fares. But a violent response from the police, prompted Brazilians of all ages took to the streets.
Suddenly the issue was about corruption, poor public services, increasing inflation, lack of security and whether the money being spent on the World Cup might be better invested elsewhere.
With a subtext of the rich lining their pockets, while the poor pay more to use crumbling public services, the Brazilian government was left scrambling to deal with what some have dubbed the "Tropical Spring."
FIFA president Sepp Blatter, for one, was askance at the protests.
"I can understand that people are not happy, but they should not use football to make their demands heard," Blatter told Brazil's Globo TV.
While FIFA argues that Brazil, as well as Russia and Qatar in 2018 and 2022, will gain benefits from infrastructure development and tourism as well as the kudos of staging a global sporting event, the World Cup is key for the world governing body -- the event is its major source of revenue.
"The exact number I do not know but around $4 billion," said FIFA secretary general Jerome Valcke earlier in June, referring to what the 2014 World Cup will generate financially for the Swiss-based organization.
However, that is a conservative estimate with consultants suggesting the amount could reach $5 billion.
"Of course it's not all profit, it is commercial revenue related to the cycle of not just the World Cup, but the cycle between the 2010 Cup and 2014," added Valcke.
Three years ago the World Cup in South Africa raised $3.6 billion, incurring expenditures of $1.298 billion.
For its latest results, FIFA reported a profit of $89 million for 2012, with reserves of $1.378 billion.
The organization had a revenue of $1.166 billion last year and spending of $1.077 billion. As a not-for-profit association in Swiss law, FIFA pays no tax on commercial income from the World Cup.
But some critics question whether the relationship between FIFA and its World Cup hosts is mutually beneficial, notably with regard to the lucrative tax exemptions World Cup organizers are prepared to offer for the right to stage the biggest single-event sporting competition in the world.
According to Brazil's Internal Revenue Service the tax exemptions will cost $248.7 million, though other reports estimate the figure could be as twice as high for the period between 2011 and 2015. The International Olympic Committee will receive similar exemptions when the South American country hosts the Olympics in 2016.
Proponents argue hosting the World Cup brings billions more dollars into the Brazilian economy, but $250 million buys a lot of bus tickets.
Brazil in "FIFA's hands"
Ex-Brazilian star Romario -- now a Brazilian politician -- is one that argues that the money spent on building stadiums would be better spent on constructing houses and schools.
"FIFA will make a profit of four billion reais ($1.8 billion) which should provide one billion ($450 million) in tax, but they will not pay anything," Romario said in a video posted on the websites of several Brazilian newspapers.
"They come, set up the circus, they don't spend anything and they take everything with them.
"The real president of our country is FIFA," added Romario. "FIFA comes to our country and sets up a state within a state."
Another critic -- academic and journalist Christopher Gaffney, who lives in Rio -- believes that FIFA's much vaunted "Fair Play" slogan should not just apply to on-field behavior.
"FIFA should be obliged to follow the pre-existing tax laws in the host countries that apply to international sports non-governmental organizations and their corporate partners," said Gaffney.
