Businesses in Iyyappanthangal looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. Iyyappanthangal sits on Mount Poonamallee Road beside its MTC bus depot, in the hospital shadow of the Porur medical belt, with pharmacies, diagnostic collection centres, supermarkets and apartment builders filling the frontage towards Kattupakkam and Mangadu. Builders selling under-construction flats at the 1 and 5 per cent rates without input tax credit, and pharmacies handling 5, 12 and 18 per cent medicine slabs, drive most GST queries. We serve this belt — including Porur and Kattupakkam — with fixed fees quoted upfront, a written document checklist, and filings completed ahead of statutory due dates. Every acknowledgement is shared the day it is generated, and our support continues if the department raises any query on work we have filed.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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.
We tell you when the composition scheme stops making sense, when QRMP suits your cash flow, and when a supplier's non-compliance is quietly costing you credit. Filing is the minimum; helping you make better GST decisions is the actual job.
Winding up attracts its own GST obligations — the cancellation application, reversal of credit on closing stock, and the final return in GSTR-10 within three months. We close registrations properly so a business you shut in Iyyappanthangal never writes back to you as a demand years later.
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.
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.
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.
Correct, complete tax invoices signal a well-run business to customers, vendors and banks alike, quietly strengthening your credibility in every transaction where your paperwork is seen.
Interest on delayed GST payment runs at 18 percent per annum, which is costlier than most working capital finance. Timely computation and payment through our calendar keeps that meter permanently at zero.
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.
Complete RFD-01 applications with proper statements and annexures move through the system faster and attract fewer deficiency memos, which means export and inverted-duty refunds reach your bank account sooner.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
Circular No. 164/20/2021-GST dated 06.10.2021 · 2021-10-06
This circular settled several long-running food service disputes. It clarified that service by cloud kitchens and central kitchens is restaurant service attracting 5 per cent without input tax credit, while ice cream parlours that sell already manufactured ice cream without any element of cooking supply goods and attract the applicable goods rate with credit. It also clarified the treatment of coaching services supplied under a government scholarship scheme, overloading charges recovered at toll plazas, and services in relation to admission to amusement parks.
Why this matters: A Chennai cloud kitchen bills at 5 per cent without credit, but an ice cream parlour selling tubs and cones must charge the goods rate and can keep its credits.
Notification No. 17/2021-Central Tax (Rate) dated 18.11.2021 · 2021-11-18
With effect from 1 January 2022, restaurant service supplied through an electronic commerce operator was notified under section 9(5) of the CGST Act. The operator, such as a food delivery platform, became liable to collect and pay the tax on those supplies instead of the restaurant, except where the restaurant is located in specified premises. The same notification also brought passenger transport by omnibus and certain motor vehicles supplied through an operator within section 9(5). Restaurants continue to report such supplies but do not pay tax on them.
Why this matters: A Chennai restaurant selling through a delivery app should show those sales separately in GSTR-3B as supplies on which the operator pays tax, and must not pay tax on them again.
GSTN Advisory dated 7 June 2025 — non-editable auto-populated liability in GSTR-3B · 2025-06-07
After an October 2024 advisory and a January 2025 deferment, GSTN confirmed that from the July 2025 tax period the auto-populated outward tax liability in GSTR-3B, drawn from GSTR-1, IFF or GSTR-1A, is hard-locked and cannot be edited manually while filing. Any correction to sales figures must be made through GSTR-1A before GSTR-3B is filed. The change is intended to end mismatches between GSTR-1 and GSTR-3B.
Practical effect: Reconcile sales data before filing GSTR-1 each month, since GSTR-3B can no longer be adjusted at the last minute.
