Frequently Asked Questions

 

1. Can an OPC opt for the QRMP Scheme if its aggregate turnover exceeds the prescribed threshold during the financial year?

No. If an OPC’s aggregate turnover exceeds the threshold prescribed under the GST law, it becomes ineligible for the QRMP Scheme and must shift to the applicable GST return filing mechanism from the relevant tax period.

2. Is an OPC required to file GSTR-1 even if there are no outward supplies during the month?

Yes. A GST-registered OPC required to file monthly GSTR-1 must file a Nil GSTR-1 if no outward supplies were made during the tax period, unless exempt under the applicable GST provisions.

3. Can an OPC revise a GSTR-3B return after it has been filed?

No. GSTR-3B cannot be revised after filing. Any omission or error must be rectified in a subsequent GST return within the time limits prescribed under the CGST Act, 2017.

4. Is Form 131 required to be issued if no tax has been deducted during the quarter?

No. Form 131 is required only where tax has actually been deducted under the applicable TDS provisions of the Income Tax Act, 2025.

5. Is an OPC required to file both GSTR-1 and GSTR-3B under the QRMP Scheme?

No. Under the QRMP Scheme, an OPC files GSTR-1 quarterly (or uses the Invoice Furnishing Facility (IFF) for the first two months of the quarter) and files GSTR-3B quarterly, while making monthly tax payments through PMT-06, wherever applicable.

6. Can an OPC claim Input Tax Credit if the supplier has not furnished invoice details in GSTR-1?

Input Tax Credit is available only if the conditions prescribed under Section 16 of the CGST Act, 2017 are satisfied, including the reflection of eligible invoice details in the recipient’s auto-generated statement, wherever applicable.

7. Is an OPC required to deduct TDS on the purchase of immovable property?

Yes. An OPC purchasing immovable property, other than agricultural land, may be required to deduct TDS if the consideration or stamp duty value meets the prescribed threshold. Form 141 must then be filed within the applicable timeline.

8. Can an OPC delay EPF and ESI payments if employee salaries are paid late?

No. EPF and ESI contributions must generally be deposited within the statutory due dates prescribed under the respective Acts. Delayed salary disbursement does not automatically extend the statutory due date for depositing contributions.

9. What records should an OPC maintain to ensure smooth statutory compliance?

An OPC should maintain GST invoices, purchase records, books of account, TDS records, payroll registers, PF and ESI records (where applicable), bank statements, and supporting documents for statutory filings to facilitate audits and regulatory inspections.

10. How can Ebizfiling help an OPC manage recurring monthly compliances?

Ebizfiling assists OPCs with GST return filing, TDS compliance, PF return filing and ESI registration, ROC compliance, due-date tracking, compliance reminders, and expert support to help businesses meet statutory deadlines accurately and avoid unnecessary penalties.
