Kolkata, Jun 28 (PTI) West Bengal Chief Minister Mamata Banerjee today said her party TMC will not attend the GST roll-out programme on June 30 midnight as she flayed the "unnecessary hurry" to roll it out.

The TMC supremo termed the GST roll-out as another "epic blunder" by the Centre.

"Our Parliamentary Party has decided not to attend the 30th June, 2017 midnight programme at Parliament House to celebrate GST, as a mark of protest," she said.

"We are deeply concerned about GST implementation. After #demonetisation, this unnecessary disastrous hurry is another epic blunder of the Centre", she said on Facebook.

"We have been for GST from the beginning but are very worried now with the way the Central Government is going ahead with the implementation", she said.

"Our repeated suggestions to take some more time to properly implement GST have fallen on deaf ears. The entire business community, especially the small and medium ones, are scared and confused.

"Only 60 hours are left before this ill-planned launch and no one knows for sure what's happening!", she said.

"Essential commodities such as medicines are not available in many places and prices of various commodities are rising for lack of clarity and mismanagement", she said.

Banerjee said, "We have always been fighting for maintaining the federal structure of the country, even if Bengal at times was the lone voice and conscience of the GST Council".

She said, "There are almost 20 different taxes in the present tax regime and we felt that one single tax and integration of all markets across the country will provide big relief to all".

Having a dig at the BJP, she said, "The current ruling party at the Centre had initially strongly opposed GST for over 7 years and suddenly did a somersault on coming to office as a champion of GST".

Banejee said that the economy is not yet ready to face the GST from July 1. The 3-day strike declared by the textile industries in the country was the evidence of "our deep concerns on the lack of preparedness".

"Small business entities are not yet ready with basic requirements like invoice, accounting system, IT system, etc.

Another piece of evidence of unpreparedness comes from the fact that the 'Return Form' had to be simplified for the first 6 months as all systems are not in place.

"It is shocking that the e-Waybill System is not yet designed and states are being asked to run their own systems as a stopgap arrangement", she said.

"We feel, at least six months will further be necessary to notify all rules and procedures and give enough time to the stakeholders, particularly the small and medium enterprises to successfully implement the GST.

"Otherwise, a chaotic situation may arise in our vast economy for which the Government of India will be primarily responsible", she said.

The West Bengal chief minister expressed hope that the voices of the people and businesses will be heard by the Centre.

GST implementation concerns prompt political boycott, citing inadequate preparedness for businesses and call for delay GST implementation is the central regulatory concern, with political leaders announcing non-attendance at the roll out programme to protest and urge additional time for procedural and technical preparations. The statement highlights inadequate readiness of small and medium enterprises for invoicing, accounting and IT compliance, incomplete design of the e Waybill System, and the temporary simplification of the Return Form as evidence of operational deficiencies likely to produce disruption and economic confusion.
