I-T (tax) Department's website incometaxindiafiling.gov.in is not accessible for six days from tomorrow as the portal is being upgraded to provide more facilities like help desk.
"The current e-filing website is being revamped to a new e-filing website with additional services. The current web services will remain closed with effect from November 3 to November 8, 2012," the Central Board of Direct Taxes (CBDT) said.
The web services will resume from November 9, it added.
"...looking to the overwhelming response from the taxpayers and growth of e-filing, a new e-filing project was conceptualised in order to take the e-services to the next generation," it said.
In order to make the new portal "live", the migration of data from the old to the new set up is in process and hence the portal will not be available for the six days to file returns, the CBDT said.
Besides companies and other entities, e-filing is compulsory for individuals having total annual income of more than Rs 10 lakh.
The CBDT said under the new e-filing setup not only income tax return (ITR) forms, but also other IT forms are proposed to be made available for electronic filing along with other web-enabled services.
"The e-filing services will resume with various new additional services like multiple mode of e-filing of returns: help desk through call centre and e-mail support, provision of online forms, pre-filing of data in forms, and availability of offline e-forms," the CBDT added.
Income Tax Department had received 1.64 crore e-returns in 2011-12, up by over 81 per cent over the previous year.
As on March 31, 2012, over 1.9 crore taxpayers had registered for e-filing.
