A bench of Justices S Ravindra Bhat and A K Chawla said, "The writ petitions have failed."
The bench also dismissed the petition of Congress leader Oscar Fernandes who too had challenged reopening of his tax assessment for the same year (2011-12).
The high court had on August 16 reserved its order on the pleas of the three leaders after the Income Tax Department had contended that Rahul Gandhi's tax assessment for 2011-12 was reopened as material facts were concealed.
Senior advocate P Chidambaram, appearing for Sonia Gandhi, had said he had faith in the oral statement made by the Additional Solicitor General Tushar Mehta.
Mehta had argued that the Congress leaders had alleged mala fide on the part of the tax department but had not made any averments in this regard.
The income tax cases against the Congress leaders have arisen from the probe into the private criminal complaint filed by BJP leader Subramanian Swamy before a trial court in connection with the National Herald case.
In the complaint, Sonia, Rahul and others have been accused of conspiring to cheat and misappropriate funds by paying just Rs 50 lakh, through which the Young India (YI) had obtained the right to recover Rs 90.25 crore that the Associated Journals Ltd (AJL) owed to the Congress party.
It was alleged that YI, which was incorporated in November 2010 with a capital of Rs 50 lakh, had acquired almost all shareholdings of the AJL, which was running the National Herald newspaper.
In this process, YI had also acquired AJL's debt of Rs 90 crore.
It has already issued a demand notice for Rs 249.15 crore to YI for the assessment year 2011-12.
The department's move followed its probe on a complaint alleging that the Gandhis had misappropriated AJL's assets while transferring their shares to the newly formed Young Indian.
