In any tax system, registration is the most fundamental requirement for identification of tax payers ensuring tax compliance in the economy. Registration of any business entity under the GST Law implies obtaining a unique number from the concerned tax authorities for the purpose of collecting tax on behalf of the government and to avail Input tax credit for the taxes on his inward supplies. Without registration, a person can neither collect tax from his customers nor claim any input tax credit of tax paid by him.

In this article, we’ll cover all the aspects of registration, persons eligible for registration, manner of registration and much more.
