Most of it happens without you leaving your shop counter. Share your documents on WhatsApp, approve the prepared draft, and your GSTR-1 & GSTR-3B Monthly Filing is completed on the portal from Rs.749 — by a Chennai team that businesses across Iyyappanthangal have relied on for years.
We serve businesses on and around A. N. Elumalai Salai — 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.
GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. 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. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Iyyappanthangal follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Porur and Kattupakkam run on the same process, entirely over WhatsApp if they prefer.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
No filing leaves our desk on a junior's judgement alone. A senior GST practitioner reviews your figures, ITC claims and tax computation before submission, so errors are caught at our table and not by the department months later through a notice.
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.
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.
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.
We match your purchase register against GSTR-2B every period, follow up on invoices your suppliers have not uploaded, and ensure every rupee of eligible input tax credit is claimed. Clients routinely recover credit they were silently losing under self-filing.
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.
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.
Loan applications and government tenders routinely demand GST returns and registration documents. With everything filed and archived properly, you can produce a complete compliance file within hours instead of days.
When a business winds up, proper cancellation and a timely final return ensure the file is genuinely closed, so no demand or late-fee computation resurfaces against you long after the shutters came down.
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.
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.
E-commerce platforms continuously validate seller GSTINs and filing status. A consistently compliant registration keeps your listings active and settlements flowing, with no sudden suspension of your online sales channel.
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.
| 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. |
| When a notice arrives | A professional drafts the reply in the department's format and files it within the statutory window, such as thirty days for ASMT-11. | You face departmental language alone, and a missed reply deadline can convert a simple query into a demand with penalty. |
| 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. |
| 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. |
| 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. |
| 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. |
A. N. Elumalai Salai is a residential street in Iyyappanthangal, about 700 m north of the centre of Iyyappanthangal. The same consultant covers the streets immediately around it — subbiyah nagar (about 300 m); Sri Devi Karumariamman Road (about 300 m); Bharathiyar Street (about 500 m); Vivekanander Street (about 550 m) — so a site visit on A. N. Elumalai Salai can usually be combined with other work in Iyyappanthangal on the same trip. For GST purposes an address on A. N. Elumalai Salai falls under the Chennai Outer CGST Commissionerate, and the Iyyappanthangal pincode is 600056.

GSTN Advisory dated 23 August 2024 — Rule 10A bank account furnishing · 2024-08-23
GSTN advised that under Rule 10A of the CGST Rules, registered taxpayers must furnish valid bank account details within 30 days of registration or before filing GSTR-1 or IFF, whichever is earlier. From 1 September 2024 the portal blocks GSTR-1 and IFF filing for taxpayers whose bank account details are not available and validated on the portal. The measure targets fraudulent registrations created without genuine banking trails.
Practical effect: Newly registered businesses should add and validate their bank account on the portal immediately after registration to avoid a filing blockage.
Tamil Nadu Water Investment Company Ltd - AAR Tamil Nadu, advance ruling reported at 2019 (2) TMI 187 · 2019
The Chennai company provided management consultancy and detailed project report services to the Chennai Metro Water Supply and Sewerage Board for water related projects. It asked whether the service attracted GST. The Authority held that the supply was a pure service with no supply of goods involved, rendered in relation to a function entrusted to a municipality, and was therefore exempt from GST under the entry covering pure services supplied to government and local authorities.
How we apply it: Chennai consultants on government water and civic projects should test the pure services exemption before adding GST to their invoices.
Notification No. 12/2017-Central Tax (Rate) dated 28.06.2017 · 2017-06-28
This notification lists the services that are wholly exempt from CGST. It covers charitable activities, most services supplied by and to Government, renting of residential dwellings for use as residence, healthcare by a clinical establishment, education by an educational institution, agricultural services, several transport exemptions and financial services such as interest on deposits and loans. Each entry has a description, a service code and often a condition. An exemption is not a zero rate: input tax credit attributable to exempt supplies has to be reversed.
Why this matters: If your Chennai business supplies anything on this list, you must reverse proportionate input tax credit under Rule 42 rather than simply enjoying a tax-free supply.
