Austria's Sportwoche mentioned speculation Hulkenberg, 25, and his teammate Paul di Resta might have been the latest victims of Force India team owner Vijay Mallya's struggling Indian airline Kingfisher.
The report cited "several" paddock sources who believe the duo have not yet been paid anything this season.
"These are rumours," Hulkenberg's manager Timo Gans is quoted by Germany's Sport1.
"I really wonder where this information comes from -- maybe people know more than we do," he added.
When asked specifically if Hulkenberg has been paid in 2012, Gans answered: "Yes."
