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. For businesses here, staying on the right side of GST is not optional — buyers check compliance, and the department's systems match every return. Our firm provides GSTR-1 & GSTR-3B Monthly Filing to clients across Iyyappanthangal and neighbouring Porur and Kattupakkam, combining Chennai jurisdiction familiarity with disciplined deadline tracking. Whether you run a shop, a service practice or a growing trading concern, we handle the portal work so you can stay focused on the business itself.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Traders, manufacturers, contractors, e-commerce sellers, professionals and service exporters — we have handled GST for all of them. Whatever mix of goods and services your Iyyappanthangal business supplies, the rate, classification and place-of-supply questions have almost certainly crossed our desk before.
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.
You are told the full fee before we begin, in writing. No surprise additions for uploads, revisions or acknowledgements. Government fees and taxes, where applicable, are shown separately, so businesses in Iyyappanthangal always know exactly what the engagement costs them.
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 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-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.
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 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.
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.
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.
Because turnover in your GST returns is kept aligned with your accounts through the year, income tax filing and statutory audit proceed without the GST-versus-books mismatch queries that now surface routinely through data matching.
Rates, reverse charge, place of supply and blocked credits are applied correctly at the preparation stage, so you neither overpay tax you do not owe nor underpay and invite demands with penalty later.
Statutory windows such as thirty days for an ASMT-11 reply are tracked from the day a notice arrives, so responses go in on time, complete, and with your best case properly presented.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |

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.
Practical effect: Chennai consultants on government water and civic projects should test the pure services exemption before adding GST to their invoices.
K.P. Mozika v. Oil and Natural Gas Corporation Ltd — Supreme Court, Civil Appeal No. 3548 of 2017, judgment dated 09-01-2024 · 2024-01-09
The Supreme Court examined contracts for supplying cranes, tankers and vehicles to ONGC. It held that a transfer of the right to use goods requires the customer to obtain effective control and legal right to use the goods to the exclusion of the owner. Where the owner retains the operator, control and responsibility, the arrangement is a service contract and not a deemed sale. Sales tax or VAT was therefore not attracted; service tax was.
What to do about it: Chennai transport, crane and equipment hire businesses should draft contracts carefully, since who controls the asset decides whether GST applies as a supply of service or of goods.
Notification No. 03/2022-Central Tax (Rate) dated 13.07.2022 · 2022-07-13
Giving effect to the 47th GST Council's rate rationalisation, this notification raised the rate on works contract services supplied to the Central Government, State Government, Union territory and local authorities from 12 per cent to 18 per cent with input tax credit, applying from 18 July 2022. Several High Courts, including the Madras High Court, have since heard petitions by contractors seeking reimbursement of the differential tax from the awarding department on contracts priced before the change.
How we apply it: Chennai civil contractors with pre-July 2022 government tenders should pursue a differential-tax claim with the department rather than absorbing the 6 per cent increase.
