Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
GSTR-1 & GSTR-3B Monthly Filing in Kotturpuram does not have to mean portal errors, guesswork and due-date tension. For a fixed fee starting Rs.749, an accountable Chennai practice prepares, reconciles, reviews and files — and remains answerable long after the acknowledgement arrives.
We serve businesses on and around 3rd Loop Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.
Share your number — a senior GST consultant calls you back within 30 minutes.
Kotturpuram, on the south bank of the Adyar around the Anna Centenary Library and the Housing Board blocks, is a professionals' quarter: independent consultants, architects, tutors and clinics work along Gandhi Mandapam Road and the numbered Main Roads. Many consultants billing from home offices cross the Rs.20 lakh services threshold quietly, and those serving overseas clients need a live LUT before invoicing exports without IGST. From a first registration to the annual return, the full range of GSTR-1 & GSTR-3B Monthly Filing is available to Kotturpuram businesses without stepping far from the shop or office — documents travel over WhatsApp, and our Chennai premises are open to anyone who prefers a face-to-face discussion. We serve Adyar and Nandanam on the same footing, applying one rule everywhere: reconcile before filing, file before the due date, and keep the client informed at every stage.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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 Kotturpuram are comfortable with, and keeps written communication simple and jargon-free.
If a query, ASMT-10 scrutiny notice or DRC-01 arrives on a return we filed, we stand behind our work and help you draft the reply. You are not left alone with a departmental letter and a thirty-day clock ticking against you.
Quarterly filing still demands monthly attention — IFF uploads so your buyers see their credit on time, and tax payment through PMT-06 by the 25th for the first two months of each quarter. We run that monthly rhythm so QRMP saves you effort without creating gaps.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Kotturpuram. 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.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
The annual return and, where turnover crosses Rs.5 crore, the self-certified reconciliation statement in GSTR-9C are prepared by the same team that filed your monthly returns. Nothing about your year has to be rediscovered or explained to a stranger in December.
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.
Timeline: Filed before the 11th and 20th of every month · No hidden charges · GST invoice provided
Rs.7,999/year
Practical outcomes our clients measure us by.
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.
The hours you or your accountant spent wrestling with the portal, JSON errors and reconciliations every month return to sales, operations and customers, while trained hands manage the compliance in the background.
Your billing staff are guided on invoice fields, rates and series discipline, so mistakes are prevented where they originate — at the counter — instead of being repaired later in the returns.
Tax positions, rate choices and credit calls are documented as they are made, so if a question arises years later, the reasoning and evidence are on file rather than in someone's fading memory.
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.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| Annual return preparation | Monthly reconciliations roll naturally into GSTR-9, filed comfortably before 31 December with figures already agreed through the year. | Twelve months of unmatched data reconstructed in December, with differences discovered too late to be corrected cleanly. |
| 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. |
| 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. |
| 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. |
| 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. |
3rd Loop Street is a residential street in Kotturpuram, about 150 m east of the centre of Kotturpuram. The same consultant covers the streets immediately around it — Link Street (about 150 m); 2nd Main Road (about 150 m); Yadaval Street (about 200 m); Kotturpuram 1st Main Road (about 200 m) — so a site visit on 3rd Loop Street can usually be combined with other work in Kotturpuram on the same trip. For GST purposes an address on 3rd Loop Street falls under the Chennai South CGST Commissionerate, and the Kotturpuram pincode is 600085.

Notification No. 18/2022-Central Tax · 2022-09-28
This notification brought most of the Finance Act, 2022 amendments into force from 1 October 2022. Section 16(4) was amended so that input tax credit for a financial year can be claimed up to 30 November of the following year instead of the due date of the September return. The same deadline now applies to issuing credit notes under Section 34 and to rectifying errors in GSTR-1 and GSTR-3B. Section 41 was also substituted to remove provisional credit and sequential filing of returns was mandated.
Practical effect: A Chennai business gets until 30 November to pick up missed credit and to issue credit notes for the previous year, which is the single most important annual deadline after the returns themselves.
Union of India v. Bharti Airtel Ltd — Supreme Court, 2021 · 2021-10-28
Bharti Airtel sought to rectify its GSTR-3B for July-September 2017 to claim refund of about Rs 923 crore excess cash paid, blaming the non-operational GSTR-2A at the time. The Supreme Court set aside the Delhi High Court order permitting rectification, holding that returns can only be corrected in the period in which errors are noticed, as the law then stood, and that taxpayers must self-assess from their own books, not the portal.
Why this matters: File GSTR-3B accurately the first time — correct discovered errors in the current period per the prescribed mechanism rather than expecting retrospective revision of old returns.
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.
Why this matters: Clear every pending old return now, because once the three-year window closes the portal will not accept the return and registration consequences follow.
