Every locality in Chennai has its own commercial rhythm, and Tambaram is no exception. Tambaram is the southern suburbs' trading hub: wholesale and retail clusters around Duraisamy Reddy Street and Gandhi Road in West Tambaram, MEPZ-SEZ exporters at Tambaram Sanatorium and institutions like Madras Christian College. Suppliers to MEPZ units must execute zero-rated supplies under LUT with proper endorsements, and wholesalers carry chronic ITC mismatch exposure from multi-supplier purchases. Our practice has shaped its GSTR-1 & GSTR-3B Monthly Filing work around exactly these realities, serving clients in Tambaram as well as Chromepet and Selaiyur. 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.
You receive a WhatsApp message when documents are received, when the draft is ready for your approval, and when the return or application is filed, along with the acknowledgement. You never have to call and ask what is happening with your file.
You deal with one accountable person who knows your business, your turnover pattern and your filing history. No repeating your story to a new voice every month, and no file falling between two desks when a deadline is approaching.
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.
GST is confusing enough without a language barrier. Our team explains notices, tax positions and filing requirements in plain Tamil or English, whichever you and your staff in Tambaram are comfortable with, and keeps written communication simple and jargon-free.
GSTR-3B late fees run at Rs.50 per day and interest at 18 percent per annum on unpaid tax. Our internal cut-offs sit days ahead of statutory due dates precisely so that our clients never hand the department a rupee they did not owe.
Tally, Zoho Books, Busy, marketplace reports, plain Excel or even a handwritten bill book — we take your data in whatever form your Tambaram business already maintains it. You are never forced to buy new software or retrain staff just to become our client.
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.
Late-fee waivers and amnesty windows notified by the GST Council are applied to your history within their deadlines, capturing reliefs that most businesses only hear about once the window has already closed.
We spot suppliers who stop uploading invoices or filing returns and alert you before their default becomes your blocked credit, letting you recover amounts or switch vendors while the exposure is still small.
With returns filed ahead of the statutory due dates every period, the Rs.50-per-day GSTR-3B late fee simply stops appearing in your life, and the money stays in your business where it belongs.
Statutory windows such as thirty days for an ASMT-11 reply are tracked from the day a notice arrives, so responses go in on time, complete, and with your best case properly presented.
Continuous filing protects you from the suspension and cancellation proceedings that hit chronic non-filers, so your registration, e-way bill access and ability to issue tax invoices are never suddenly cut off.
Systematic GSTR-2B matching and supplier follow-up mean input tax credit that was leaking away under self-filing is captured each month, directly reducing the cash you pay out with every GSTR-3B.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| Record keeping | Every return, challan, acknowledgement and working paper archived in an organised folder, retrievable in minutes years later. | Documents scattered across email, downloads and old phones; assembling records for a bank or an audit takes days. |
| 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. |
| Risk of notices | GSTR-1, GSTR-3B and GSTR-2B reconciled before filing, removing the mismatches that trigger most scrutiny notices. | Inconsistent figures across returns quietly build a mismatch history that surfaces later as ASMT-10 scrutiny or a demand notice. |
| Time cost | Roughly an hour a month to send data and approve drafts; the portal work, reconciliation and follow-up are ours. | Hours every month lost to portal errors, JSON files, OTP failures and reworking figures — usually on the due date itself. |
| Supplier defaults | Suppliers who stop uploading invoices are identified within the period and pursued before their default becomes your blocked credit. | Missing supplier invoices surface only when credit is denied, by which time recovering the amount from the vendor is difficult. |
| Registration and amendments | Query-resistant applications prepared correctly the first time, with supporting documents matched to what proper officers actually verify. | Repeated clarification memos and resubmissions, with weeks lost because a rent agreement or premises photograph did not meet expectations. |
Kakkan Street is a residential street in Tambaram, about 1.7 km west of the centre of Tambaram. The same consultant covers the streets immediately around it — Shanmugam Road (about 300 m); Venkatesan Street (about 300 m); Tambaram - Somangalam Road (about 350 m); Tambaram - Mudichur - Sriperumbudur Road (about 350 m) — so a site visit on Kakkan Street can usually be combined with other work in Tambaram on the same trip. For GST purposes an address on Kakkan Street falls under the Chennai Outer CGST Commissionerate, and the Tambaram pincode is 600045.

A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
44th GST Council Meeting (video conferencing) — 12 June 2021 · 2021-06-12
Acting on a Group of Ministers report, the Council cut rates on COVID relief goods until 30 September 2021. Tocilizumab and Amphotericin B moved to nil, while Remdesivir and anti-coagulants such as heparin were reduced to 5 per cent. Medical grade oxygen, oxygen concentrators, ventilators, BiPAP machines, COVID testing kits and specified diagnostic kits all moved from 12 to 5 per cent. Pulse oximeters, hand sanitiser, temperature check equipment and crematorium furnaces moved to 5 per cent, and ambulances from 28 to 12 per cent.
What it means for you: These were temporary rates with a hard expiry, so suppliers must be able to show that concessional invoices fall inside the notified relief period.
Tamil Nadu Labour Welfare Board - AAR Tamil Nadu, advance ruling reported August 2021 · 2021
The Board, based at the DMS Campus in Teynampet, Chennai, owned immovable property and let portions of it to government departments and business entities. It asked whether it needed registration and whether the rent was exempt because the tenant was the government. The Authority held that renting of commercial property by the Board to a government or a business entity is not an exempt supply, so GST was payable on the rent collected.
How we apply it: Chennai landlords letting premises to government offices must charge GST unless a specific exemption entry clearly covers the letting.
GSTN Advisory dated 7 June 2025 — barring of GST returns after three years (Finance Act, 2023; Notification No. 28/2023-Central Tax) · 2025-06-07
Implementing the Finance Act, 2023 amendments to Sections 37, 39, 44 and 52, notified by Notification No. 28/2023-Central Tax, GSTN advised that from the July 2025 tax period the portal blocks filing of GST returns once three years have passed from their due date. The bar covers GSTR-1, GSTR-1A, GSTR-3B, GSTR-4, GSTR-5, GSTR-5A, GSTR-6, GSTR-7, GSTR-8 and GSTR-9. Taxpayers with old pending returns were urged to reconcile their records and file before the returns became permanently time-barred on the portal.
Practical effect: Clear every pending old return now, because once the three-year window closes the portal will not accept the return and registration consequences follow.
