“In preparation for the transition to the new system, the existing e-filing portal will not be available to both taxpayers as well as department officers for a period of six days from June 1 to June 6,” the notice said.

The income tax department will launch a new e-filing portal on June 7, the directorate of income tax systems said in a notice to all field units, adding that services on the portal will not be available from June 1 till June 6.

The portal will not be available for taxpayers as well as department officers and therefore officers have been directed not to fix any compliance dates during the six day period.
