How to Fill Out and File the GSTR-3B

If you collect GST, you need to file the GSTR-3B by the 20th of every month. The form looks a bit complicated, but filling out the form is easier than it appears at first glance. So, here’s an overview of the essentials.

Do You Need to File a GSTR-3B Return?

Typically, if your business is registered under the GST scheme, you have to file this form, but there are a few exceptions. In particular, if you fall into any of the following categories, you don’t have to worry about this form:

  • Composition Dealers
  • Input Supply Distributors
  • Suppliers of Online Information
  • Non-Resident Taxable Individuals
  • Additionally, you don’t have to file if your business provides online database access and retrieval services, such as selling e-books or online gaming.
