What is the GST Number?

Every taxpayer registered under the GST regime is given a 15-digit alphanumeric code called their GSTIN (Goods and Services Tax Identification Number). The GSTIN is a special number that aids in the tracking of tax transactions by various firms around the country by the tax authorities. It comprises five parts:

  • The first two digits of a GSTIN are the state code

  • The next ten are the taxpayer's PAN

  • The entity code number of registrations on that PAN in that state is the thirteenth digit

  • The default letter Z is the fourteenth digit

  • The fifteenth digit is an alphanumeric cheque code

Before the implementation of GST, many indirect tax regulations used tax identification numbers such as TINs and Service Tax Nos., which were replaced by GSTINs. For every state or union territory in which it conducts business, a business that is required to register under the GST Act must acquire a GSTIN. Businesses need this number to file GST returns, obtain input tax credits, issue GST invoices, and adhere to all applicable GST laws and regulations.

What is GST Registration?

When a business's revenue is above the threshold of either Rs. 40 lakhs, Rs. 20 lakhs, or Rs. 10 lakh, the owner of the business is required to register under the Goods and Services Tax (GST) as a regular taxable person. This process is referred to as GST registration. It is illegal for a company to conduct business without a GST registration, and certain businesses are required to register for GST. There are several types of GST registration under the GST Act. Before choosing the right kind of GST registration, you need to be informed of the many kinds. The many forms of GST Registration include: 

  • Normal Taxpayer: In India, the majority of enterprises fit under this group. To become an ordinary taxpayer, you do not have to make any deposits. For taxpayers in this category, there is likewise no expiration date. 

  • Casual Taxable Person: This category is for people who want to open a temporary store or booth. When the stall or seasonal shop is open, you have to pay a deposit in advance equal to the anticipated GST liability. Under this category, the GST Registration has a three-month validity that can be renewed or extended. 

  • Composition Taxpayer: Submit an application to be eligible for the GST Composition Scheme. This category requires a one-time flat deposit. The Input Tax Credit is not applicable to this category.

  • Non-Resident Taxable Person: If you are based outside of India yet sell goods to residents, select this type of GST registration. Similar to the Casual Taxable Person type, you must pay a deposit equivalent to the estimated GST liability while the GST registration is active.

  • Persons registered with the tax services before the GST law was implemented
