Every locality in Chennai has its own commercial rhythm, and Kodungaiyur is no exception. Kodungaiyur spreads north from Erukkancheri High Road across the MMDA blocks, Muthamizh Nagar, Ezhil Nagar and Kaviarasu Kannadasan Nagar, with plastic and paper recycling units clustered around the Kodungaiyur dumping ground, small engineering workshops, hardware dealers and provision stores along Kodungaiyur Main Road and the Milk Colony approach. Scrap bought from unregistered vendors, reverse charge liability and e-way bills on waste consignments trigger most notices. Our practice has shaped its GSTR-1 & GSTR-3B Monthly Filing work around exactly these realities, serving clients in Kodungaiyur as well as Erukkanchery and Moolakadai. Registrations, returns, refunds and notice replies are handled by one accountable team, with fees fixed in writing before work begins and every filing reconciled against portal data before it is submitted.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
In the days before the 11th and the 20th, our team runs extended hours and a strict internal queue, so a client who sends data late in the window is still filed on time. Peak-season crush at our end never becomes a late fee at yours.
If your GSTR-1 and GSTR-3B start drifting apart, if a large supplier stops filing, or if your turnover approaches the e-invoice threshold, we flag it to you immediately. Early warnings from our side are cheaper than departmental letters later.
Sellers on Amazon, Flipkart and other marketplaces face a three-way match between marketplace reports, GSTR-1 and the TCS the operator deposits against your GSTIN. We reconcile all three every period and accept the TCS credit, so sellers in Kodungaiyur never leave marketplace deductions unclaimed.
From filing the LUT in RFD-11 at the start of each financial year to preparing RFD-01 refund claims with complete annexures, we know what makes a refund file move. Exporters and inverted-duty businesses come to us specifically for this.
Composition dealers have their own rulebook — CMP-08 every quarter, GSTR-4 annually by 30 June, bills of supply instead of tax invoices, and a turnover ceiling that must be watched. We handle each of these correctly so the scheme's simplicity never turns into a violation.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Kodungaiyur. We know how local proper officers examine registrations, what supporting documents they routinely call for, and how to present a file so it moves without repeated queries.
At month end we remind you and collect sales invoices, purchase bills and credit notes in whatever format you maintain, including Excel, Tally exports or scanned copies.
We prepare invoice-wise outward supply details, validate GSTINs of your B2B customers, summarise B2C supplies and file GSTR-1 on the portal before the 11th.
We download your auto-drafted GSTR-2B, match it against purchase records, and claim only eligible input tax credit so that mismatches do not trigger scrutiny notices later.
We compute net tax payable after ITC set-off, share the working with you for approval, and generate the payment challan for any cash liability.
After your confirmation and tax payment, we file GSTR-3B before the 20th and send you both filed acknowledgements along with a one-page summary of the month.
Send these on WhatsApp (+91 - 9600 606 444) and we take it forward the same day.

Practical outcomes our clients measure us by.
When a business winds up, proper cancellation and a timely final return ensure the file is genuinely closed, so no demand or late-fee computation resurfaces against you long after the shutters came down.
Correct e-way bills matched to correct invoices mean your consignments clear roadside inspections cleanly, avoiding detention proceedings whose penalties can far exceed the tax on the goods being carried.
Because turnover in your GST returns is kept aligned with your accounts through the year, income tax filing and statutory audit proceed without the GST-versus-books mismatch queries that now surface routinely through data matching.
Filed returns, challans, reconciliations and working papers are archived in order from day one. If an audit or departmental verification comes, your file is ready the same week, not assembled in a panic.
With the LUT filed at the start of each financial year and refund claims tracked to credit, exporters supply without blocking funds in IGST and recover accumulated credit on schedule.
Getting IGST versus CGST and SGST right at the invoice stage spares you the painful cycle of paying the correct head again and pursuing a refund of the amount paid under the wrong one.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| Due-date tracking | A maintained compliance calendar with internal cut-offs days before the 11th and the 20th; we chase you for data, not the other way around. | Deadlines remembered from memory or phone alarms; one busy week and the return slips past the due date. |
| Late fees and interest | Filings go in ahead of statutory dates, so the Rs.50-per-day late fee and 18 percent interest never arise. | Late fees accumulate silently every delayed day, and interest on unpaid tax runs at 18 percent per annum. |
| When a notice arrives | A professional drafts the reply in the department's format and files it within the statutory window, such as thirty days for ASMT-11. | You face departmental language alone, and a missed reply deadline can convert a simple query into a demand with penalty. |
| Keeping up with changes | Rate changes, portal updates and new thresholds such as the Rs.5 crore e-invoice limit are tracked by us and applied to your case proactively. | Changes are discovered after the fact — often through a rejected filing, a blocked e-way bill or a departmental letter. |
| Goods in transit | E-way bills generated correctly and matched to invoices, so consignments pass roadside inspections without detention or penalty. | A defective or missing e-way bill can mean detention at a checkpoint, with penalties that dwarf the tax on the consignment. |
| Refund claims | RFD-01 filed with complete statements and annexures, tracked from ARN to bank credit, with any deficiency memo answered promptly. | Incomplete claims bounce back as deficiency memos while the refund sits unclaimed for months and working capital stays blocked. |

17th GST Council Meeting, New Delhi — 18 June 2017 (PIB Release ID 1493128) · 2017-06-18
Responding to trade concerns about return readiness, the Council decided that for the first two months of GST, tax would be payable on a simple summary return, Form GSTR-3B, filed by the 20th of the following month. Invoice-wise details in GSTR-1 for July 2017 were to be filed between 1 and 5 September and for August between 16 and 20 September, with GSTR-2 auto-populated thereafter. This is the origin of the summary return that has governed monthly GST compliance ever since.
Practical effect: GSTR-3B was designed as a two-month stopgap and is still the return every Chennai business files monthly, which is why its legal status has been litigated repeatedly.
GSTN Advisory, April 2024 — reset and re-filing of Form GSTR-3B for certain identified taxpayers · 2024-04
GSTN found that in a small number of cases credit or liability figures had been wrongly auto-populated into GSTR-3B. The affected returns were reset and made available for filing afresh. Only the taxpayers identified by the system saw the option on their dashboard and they were given a short window to verify the figures and file again. No general facility to revise a filed GSTR-3B was created.
Why this matters: A filed GSTR-3B still cannot be revised as a rule, so verify the auto-populated figures carefully before you submit the return.
Taghar Vasudeva Ambrish v. Appellate Authority for Advance Ruling, Karnataka, W.P. No. 14891 of 2020, Karnataka High Court, judgment dated 7 February 2022, affirmed in State of Karnataka v. Taghar Vasudeva Ambrish, Civil Appeal Nos. 7846-7847 of 2023, 2025 INSC 1380, judgment dated 4 December 2025 · 2022-02-07
Co-owners had let a residential building to a company that ran it as a hostel for students and working professionals. The advance ruling authorities denied exemption on the view that the lessee was using the property commercially. The High Court disagreed and held that leasing residential premises used as a hostel falls within Entry 13 of the IGST services exemption notification, since that entry does not require the lessee itself to occupy the premises as a residence. The Supreme Court dismissed the State's appeals on 4 December 2025 and confirmed that the end use as a residence, not the intermediate commercial layer, decides the question.
Practical effect: Chennai property owners letting buildings to hostel operators now have Supreme Court backing for periods before 18 July 2022, though later periods must also account for the registered-tenant reverse charge.
