The policy-making body of the tax department issued an order, under Section 119 of the Income Tax Act, late night, extending the deadline.
The CBDT had last extended the deadline on March 27.
The latest order said the deadline for the PAN-Aadhaar linking for filing I-T returns was being extended after “consideration of the matter”.
It is understood that the fresh CBDT order has come against the backdrop of the Supreme Court earlier this year directing extension of the March 31, 2018 deadline for linking Aadhaar card with various other services.
The apex court had ordered that the deadline be extended till the five-judge constitution bench delivers its judgment on petitions challenging the validity of the biometric scheme and the enabling law.
