The Central Board of Direct Taxes (CBDT) said a proposed new online tax payment system and a mobile app on its soon-to-be launched advanced e-filing website will be activated on June 18 even as the portal will go live on Monday. The new e-filing link — www.incometax.gov.in — will replace the existing “http://existing www.incometaxindiaefiling.gov.in” from June 7.
