Also, existing excise, service tax and VAT assessees will get another chance to migrate to the GSTN portal as registration for them too opens on Sunday next and will remain open for three months.
The GSTN portal will now start accepting fresh registrations from June 25.
GSTN, the company providing IT backbone for the new tax regime, will offer another opportunity to existing tax payers to migrate, five days before the rollout of Goods and Services Tax (GST).
Out of the 81 lakh existing assessees, over 65.5 lakh have already migrated to the portal.
Registration with the GSTN is necessary for doing business in the GST regime as businesses will have to upload monthly supply data as well as file return forms on this portal.
"People should not panic. If you are left out, you will get another opportunity because the law says anybody who is registered under taxes which are subsumed under GST if they have a valid PAN then they will be given a valid registration," GSTN Chairman Navin Kumar said.
The portal will also be opened for enrolment of GST practitioners on June 25.
The GSTN portal was open from November 8 till April 30 and then again for 15 days in June for enrolment of existing taxpayers.
It will now be open againfrom June 25thfor a period of 3 months for existing taxpayers registered under Central Excise/Service Tax/VAT etc, the statement said.
