GST a done deal with AIADMK's positive intention?

Even as media reports are abuzz with how GST bill clearance will benefit which sectors , the impasse over Goods and Service Tax (GST) bill seems to be coming to an end with the All India Anna Dravida Munnetra Kazhagam (AIADMK) hinting at a resolution over the bill. AIADMK has put the ball in centre's court while claiming that the GST bill won't get passed without AIADMK's support. 

Out of 6 specifications requested, the centre has agreed on 1, even as Tamil Nadu  (TN) in one of its major specifications has requested for a compensation for itself for 5 years, arguing that a state like TN should not be penalised for doing good. 

Tamil Nadu has been raising concerns over the GST bill arguing that the bill will impact the fiscal autonomy of the state. If GST bill gets  implemented, TN government fears it will not have enough resources to manage the fiscal expenses it is already committed to. 

The GST bill touted to add 1 per cent to the GDP  if implemented is going to be the biggest tax reform in India. Current government is desperate to pass the bill and faces opposition from Congress even as the Lok Sabha has already cleared the bill. GST will bring the country under a unified tax regime.
