Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Korattur permanently ahead of both, delivering GSTR-1 & GSTR-3B Monthly Filing from Rs.749 with reconciliation, senior review and WhatsApp acknowledgements as standard.
We serve businesses on and around 45th Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

Korattur, between the Padi flyover and Ambattur on the MTH Road corridor, mixes tier-2 auto component and fabrication units feeding Lucas TVS and the Ambattur estate with dense retail around Korattur railway station and the lake. Vendor units here must reconcile OEM debit and credit notes against GSTR-2B every month, because a single unmatched note can block input tax credit for a quarter. We have supported businesses of exactly this profile with GSTR-1 & GSTR-3B Monthly Filing across Korattur for years, along with clients from Padi and Ambattur. 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.
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.
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.
A registration cancelled for non-filing is not the end of the road. We bring the pending returns up to date, clear the dues and file the revocation application in REG-21 within the permitted window, restoring suspended and cancelled GSTINs to active status.
Your sales figures, supplier lists and login credentials are handled only by our engaged team, stored securely and never shared with any third party. Many of our clients in Korattur compete with each other; complete confidentiality is a condition of our work.
GSTR-1 requires four-digit HSN reporting for turnover up to Rs.5 crore and six digits above it, and a wrong code often means a wrong rate. We verify the classification of what you actually supply, so your invoices and returns rest on defensible codes.
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.

Practical outcomes our clients measure us by.
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.
A fixed professional fee is almost always cheaper than the combination of late fees, interest, lost credit and staff hours that informal, last-minute compliance quietly accumulates over a year.
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.
Because monthly data is reconciled as it happens, GSTR-9 preparation before the 31 December due date becomes a review exercise rather than a painful reconstruction of twelve untidy months.
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.
Funding rounds, partnerships and business sales all begin with a compliance check. A clean, documented GST history lets you clear that scrutiny quickly instead of watching a deal stall over old filing gaps.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| Portal credentials and data | Logins handled by a small engaged team under strict confidentiality, with credentials stored securely and never passed onward. | Passwords circulating on chats with freelancers and part-timers, and no accountability for who has accessed your business data. |
45th Street is a residential street in Korattur, about 1.1 km north-west of the centre of Korattur. The same consultant covers the streets immediately around it — 44th Street (about 0 m); 42nd Street (about 50 m); 46th Street (about 100 m); 47th Street (about 100 m) — so a site visit on 45th Street can usually be combined with other work in Korattur on the same trip. For GST purposes an address on 45th Street falls under the Chennai North CGST Commissionerate, and the Korattur pincode is 600080.

M/s. Refex Industries Ltd v. Assistant Commissioner of CGST & Central Excise — Madras High Court, W.P. Nos. 23360 & 23361 of 2019, decided 6 January 2020 (Anita Sumanth J.) · 2020-01-06
The department demanded interest on the entire tax shown in belated GSTR-3B returns, including the part discharged from input tax credit. The Madras High Court held that interest under Section 50 is compensatory, and can be levied only on the belated cash payment of tax, not on input tax credit that was lying with the department all along. The proviso inserted in Section 50(1) was treated as curative and applicable to earlier periods as well.
What to do about it: A Chennai business that filed GSTR-3B late should verify that any interest demand is computed only on the cash component of the tax, and contest interest charged on the ITC-set-off portion.
Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, Schedule I entries for electrically operated vehicles and chargers · 2025-09-17
Electrically operated vehicles including two-wheelers and three-wheelers, fuel cell and hydrogen vehicles, e-bicycles and chargers or charging stations for electric vehicles remain in Schedule I at five per cent. Small petrol cars up to 1200 cc and up to 4000 mm, small diesel cars up to 1500 cc and up to 4000 mm and motorcycles up to 350 cc moved to eighteen per cent, while larger cars, hybrids above those limits and motorcycles above 350 cc were placed at forty per cent.
What to do about it: The tax gap between an electric two-wheeler at five per cent and a petrol motorcycle at eighteen per cent is now the single biggest pricing lever for Chennai vehicle dealers.
4th GST Council Meeting, New Delhi — 3-4 November 2016 (Signed Minutes, Agenda Item 3) · 2016-11-03
Summing up a long debate over five-band and six-band options, the Chairperson proposed and the Council accepted a structure with one exempt category covering food grains and similar essentials, a lower rate of five per cent for goods consumed by vulnerable sections, standard rates of 12 and 18 per cent, and a higher slab of 28 per cent. A committee of officers was directed to fit individual goods and services into those slabs. Proposals for a 40 per cent slab were rejected.
How we apply it: Every rate dispute a Chennai business faces today traces back to this four-slab architecture and to the fitment exercise it launched.
