Are Purchase Details Mandatory in GSTR-4?

In the case of composition dealers who are filing GSTR-4, providing information on inward supplies from the registered suppliers (excluding reverse charge supplies) is, indeed, mandatory in Table 4A. Note that this requirement was initially waived until December 2017; it was later extended until June 2018. The reason for the same was the non-access to the auto-population facility of inward supply details.

However, as there was an introduction of the auto-drafted purchases in the GST portal, composition dealers were then required to furnish such details in GSTR-4 Table 4A, starting quarters July-September 2018 onwards.

FAQs

Are purchase details mandatory in GSTR-4 for composition taxpayers?

Yes, purchase details under Table 4A (inward supplies from registered suppliers not attracting reverse charge) are mandatory. This requirement was enforced from July–September 2018 onward. Initially, it was relaxed due to the absence of auto-populated data. But now, with the introduction of auto-drafted purchases, filing these details is compulsory for compliance.

What kind of inward supplies need to be reported in GSTR-4?

Inward supplies from both registered and unregistered suppliers, including those under reverse charge and imported services, must be reported in Table 4 of GSTR-4. This includes sections 4A, 4B, 4C, and 4D. The details ensure correct tax liability and reconciliation. Even if no reverse charge applies, reporting of non-reverse-charge purchases is required.

Why was reporting purchase details not mandatory initially?

During the early stages of GST implementation, the auto-population mechanism for inward supply data was not fully developed. To reduce compliance burden, the requirement to report such details was waived until June 2018. However, once auto-drafted purchase data became available, the GST Council made reporting mandatory to ensure accuracy and transparency.

What is the purpose of Table 4A in GSTR-4?

Table 4A captures details of inward supplies from registered suppliers, excluding those under reverse charge. This helps the government monitor purchase transactions and verify them against supplier data. It’s also useful for ensuring that no taxable supply is missed during reconciliation. The data contributes to the overall tax liability and compliance check.

What happens if a dealer omits purchase details in GSTR-4?

Omitting mandatory purchase details in GSTR-4 can lead to validation errors, mismatches, or notices from tax authorities. It may also affect the auto-drafted returns of counterparties. Inconsistent reporting undermines compliance and may result in penalties or rejection of the return. Hence, accurate and complete purchase reporting is essential.
