The FIA was set to issue compliance certificates to teams who had stayed within the $145m limit on Wednesday following a full audit.
But in a statement issued late on Wednesday afternoon, the FIA announced the certificates would now not be released until next week.
“The FIA informs that the conclusion of the analysis of the 2021 financial submissions of the Formula 1 teams and the subsequent release of Certificates of Compliance to the Financial Regulations will not take place on Wednesday, 5 October,” the statement reads.
“The analysis of financial submissions is a long and complex process that is ongoing and will be concluded to enable the release of the Certificates on Monday, 10 October.”
It means the discussion over the budget cap is set to rumble on over the Japanese Grand Prix weekend, with both Red Bull and Aston Martin denying they had breached the $145m limit last year.
Red Bull team principal Christian Horner said on Sunday he was “absolutely confident” the team had complied with the financial regulations, amid calls from rivals Ferrari and Mercedes for strict sanctions if that were not the case.
In the statement on Wednesday, the FIA repeated its comment noting “significant and unsubstantiated speculation and conjecture” concerning the budget cap.
“The FIA reiterates that until it is finalised, no further information will be provided,” the statement added.
“The FIA also reiterates that any suggestion that FIA personnel have disclosed sensitive information is equally baseless.”
