Returns (goods and service taxes)

There is no such form as "GSTR-4B" in the current GST framework. The confusion likely stems from the specific table names within the GSTR-4 annual return or a misunderstanding of other forms.

Here is the clarification regarding GSTR-4 and the term "GSTR-4B":

What is GSTR-4?

GSTR-4 is an annual return that must be filed by taxpayers registered under the GST Composition Scheme. It serves as a consolidated summary of a composition dealer's activities for the entire financial year, including:

Outward supplies.
Inward supplies (including those subject to Reverse Charge Mechanism).
Tax liability and payments made throughout the year.

What is GSTR-4B?

There is no official GST return form called "GSTR-4B."

It is common for taxpayers to get confused because "Table 4B" exists inside the GSTR-4 form. Table 4B is a specific section of the GSTR-4 return used to report inward supplies received from a registered supplier that attract tax under the Reverse Charge Mechanism (RCM).

Key Differences at a Glance

Summary:

There is no form named GSTR-4B. If you are seeing this term, it is almost certainly a reference to Table 4B of the GSTR-4 return, which is the section used to report your inward purchases that are subject to the Reverse Charge Mechanism (RCM). GSTR-4 is the annual return for composition scheme taxpayers, and it cannot be revised once filed.
