Monthly & Quarterly GST Return Compliance Practice

Executing flawless, timely Goods and Services Tax return filings is the foundation of corporate indirect tax health. Under Sections 37 and 39 of the Central Goods and Services Tax (CGST) Act, 2017, registered businesses must report outward supplies and discharge tax liabilities within strict monthly cut-offs (11th for GSTR-1, 20th for GSTR-3B). Our practice manages end-to-end multi-state return execution, reconciling sales ledgers with e-way bills and e-invoices, optimizing electronic cash ledger payments, and preventing automated portal late fees and interest under Section 50.

01

Outward Invoice Finalization (Form GSTR-1 / IFF)

We audit and upload monthly sales datasets, verifying B2B recipient GSTINs, 6-digit HSN codes, tax rates, credit/debit notes, and zero-rated export declarations. Timely GSTR-1 submission ensures immediate auto-population into your commercial buyers' GSTR-2B ledgers, avoiding business relationship friction and customer payment holdbacks.

Form GSTR-3B Summary Return & Tax Liability Discharge

We compute aggregate output tax liability across IGST, CGST, SGST, and Compensation Cess. We apply optimal tax credit offsets in accordance with Section 49 set-off rules, minimizing direct cash outflows through electronic cash ledger optimization while safeguarding input credit allocations.

03

QRMP Scheme & Form CMP-08 Quarterly Compliance

For small taxpayers opting into the Quarterly Return Monthly Payment (QRMP) scheme, we facilitate monthly tax challan deposits via Form PMT-06 using Fixed Sum or Self-Assessment methods, and execute quarterly GSTR-1 and GSTR-3B filings along with Form CMP-08 for composition dealers.

Frequently Asked Regulatory & Compliance Questions

Authoritative insights structured for executive boards, corporate proprietors, and regulatory compliance

1

Why is Section 16(2)(aa) critical for claiming GST Input Tax Credit?

Section 16(2)(aa) mandates that a registered recipient can only claim input tax credit if the details of the invoice or debit note have been furnished by the supplier in their GSTR-1 and communicated to the recipient in auto-drafted Form GSTR-2B. Claiming ITC on invoices missing from GSTR-2B violates statutory rules and triggers automated Rule 88D recovery proceedings.
Key Takeaway: No ITC is legally permissible unless the supplier has uploaded the invoice into their GSTR-1.
