Tax collection is determined by where the registered office of company is located. Tata produce car and steel in Jharkahnd, make buses in lucknow and darward, all these things are used all over india. But tax gets collected from Mumabi because registered office is there. It does not mean tax belong to mumbai. it is paid by each and every consumer of tata all over india. Come on man..accept that Mumabi is pathetic city and it sucks me every day...I am sure you also take local and pay exorbitant rent for pathetic property..I have not problem in saying that my mumbai is dying every day
