While the Indian government has in the recent past has declared its intent to move towards a unified taxation system by introducing GST, however unfortunately while excise duties, corporate and personal income tax rates are uniform across the country, sales tax, octroi and other levies actually vary between States due to the federal structure of the government. Besides, the applicable tax rates and compliance requirements also depend on business structure, the legal status of the corporate entity and nature of permanent establishment in India.
Additionally, the government has provided some exemptions to certain industries that enjoy specific tax exemptions provided they fulfil the stipulated conditions while on the other hand there are certain regulations and taxes are also subject to change each year under the provisions of the Union/State budgets.
