GST will subsume indirect taxes like VAT, Excise Duty, Service Tax, Entry Tax, Octroi, Surcharges and Cesses, etc. So, there is no question of getting Excise or Service Tax registration. The company will only be required to get registration under GST Law.
The annual exemption threshold for levy of GST would be Rs. 20 lakh but, for the north-eastern and hill states, it would be Rs. 10 lakh, as decided in the first meeting of the GST Council. This threshold limit will be applicable to every person irrespective of whether he is trader or service provider. There will be a different set of limits of turnover (yet to be decided), for registration of an entity under GST i.e. if u cross the threshold of registration you will have to get the company registered and one you cross the threshold of Rs.20lakh /10 lakh then you will be liable to pay GST.
Also, Goods and Services Tax Network (GSTN) will be opening a website for the registration of taxpayers in November 2016. The existing taxpayers, who are registered under the respective state VAT laws or Service Tax Department would not have to apply for fresh registration as there will be a system of migration of the existing database to GST database. But, they will have to provide other necessary details which are not in the database of State Commercial Tax or Service Tax Department.
As far as records are concern, as per section 42 of Draft model GST Law, every registered person shall keep and maintain a true and correct account of:
- production or manufacture of good
- inward or outward supply of goods and/or services
- stock of goods
- input tax credit availed
- output tax payable and paid
- such other particulars as may be prescribed in this behalf
Also,The Commissioner and Chief Commissioner has the power to notify a class of taxable persons to maintain additional accounts or documents for such purpose as may be specified.
So, nothing special is required to be maintained other than the accounting records usually maintained unless it is notified by the Commissioner and Chief Commissioner.
