Kathivakkam is a fishing town wedged between the Ennore Creek and the Chennai-Ennore Expressway, where Thazhankuppam and Ernavur kuppams supply fish traders and ice plants, and works contractors serve the Ennore Thermal Power Station, Ennore Foundries and the container traffic moving down Manali High Road. Labour and works contractors here face reverse charge and GST-TDS issues, and fish traders need clarity on exempt versus processed supplies. We have supported businesses of exactly this profile with GSTR-1 & GSTR-3B Monthly Filing across Kathivakkam for years, along with clients from Ennore and Ernavur. The engagement is simple: one point of contact, a clear fee, documents over WhatsApp or in person at our Chennai office, and senior review before anything is submitted on the portal. What you get in return is clean filings, archived records and far fewer reasons for the department to write to you.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Most GST notices trace back to mismatches between GSTR-1, GSTR-3B and GSTR-2B. We reconcile these before filing, not after a notice arrives, so your returns are internally consistent and the most common triggers for ASMT-10 scrutiny simply never appear.
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.
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.
Your cash ledger, credit ledger and liability register are reviewed regularly, not just at filing time. Excess balances are flagged for use or refund, and where a genuine slip surfaces, a voluntary payment through DRC-03 settles it before it can mature into a notice.
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.
Freight paid to transporters, advocate fees, imported services and other notified supplies attract GST under reverse charge, with self-invoicing where the supplier is unregistered. We maintain a running RCM check every period, because this is the liability self-filers most consistently miss.
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.
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.
Illness, travel or a family function no longer threatens a deadline. With a standing external process holding your calendar and data trail, filings proceed on schedule whether or not you are at your desk.
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.
When GST knowledge lives inside a single staff member, their resignation becomes a compliance crisis. With our firm as the standing process, your filings continue uninterrupted regardless of internal staff changes.
Large buyers check vendor GST compliance before releasing payments and renewing contracts. A clean filing record with timely GSTR-1 uploads keeps your invoices reflecting in their GSTR-2B and your payments unblocked.
When a query or verification comes, you respond through a professional who deals with the department regularly, in the department's own language and format, instead of facing an officer's letter alone.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Real notifications, rulings and case law our consultants track — and apply to client filings and notice replies.
Mr. Kannippan Arumugan v. Assistant Commissioner (ST) — Madras High Court, W.P. No. 2943 of 2026, decided 30 January 2026 (C. Saravanan J.) · 2026-01-30
The taxpayer had reported tax of Rs 2,54,040.30 against an invoice instead of the correct Rs 1,31,280.30, and a demand followed. The Court quashed the assessment order dated 21 July 2025 and remitted the matter for fresh adjudication within six months, permitting the petitioner to rectify the inadvertent error subject to compliance with Circular No. 212/6/2024-GST, and directing the officer to verify with the recipient's jurisdiction whether excess credit had in fact been availed.
What to do about it: A clerical overstatement in GSTR-1 by a Chennai supplier can still be corrected long afterwards, provided the recipient has not taken the excess credit and the Circular 212 procedure is followed.
GSTN Advisory — Invoice Management System, live from 14 October 2024 · 2024-10-14
GSTN launched the Invoice Management System (IMS) on the portal from 14 October 2024. Buyers can now view each invoice uploaded by suppliers in GSTR-1, IFF or GSTR-1A and mark it as accepted, rejected or pending. These actions determine what flows into GSTR-2B, with the first IMS-based GSTR-2B generated on 14 November 2024 for the October 2024 period. Records left without action are treated as deemed accepted.
Practical effect: Set up a monthly IMS review before your GSTR-2B is generated so wrong or fraudulent supplier invoices do not silently enter your ITC.
Notification No. 12/2019-Central Tax (Rate), dated 31 July 2019 · 2019-07-31
With effect from 1 August 2019 the GST rate on electrically operated vehicles, including two-wheelers, three-wheelers and cars, was reduced from twelve per cent to five per cent, and chargers and charging stations for such vehicles were brought to the same five per cent rate. Electrically operated vehicles were defined as vehicles running solely on electrical energy from an external source or from batteries fitted to the vehicle. The five per cent rate on electric vehicles has survived every subsequent restructuring.
How we apply it: Electric two-wheeler and three-wheeler dealers in Chennai charge five per cent, and the same rate applies to the charger sold with the vehicle.
