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 Chepauk have relied on for years.
We serve businesses on and around Mattankuppam — 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.
Chepauk is Chennai's government and sporting quarter: the M.A. Chidambaram Stadium on Wallajah Road, the Chepauk Palace secretariat offices in Ezhilagam, the University of Madras along Kamarajar Salai and hostels and eateries on Bells Road and Victoria Hostel Road. Caterers, event vendors and contractors billing government departments face 2 per cent GST TDS reported in GSTR-7, making monthly credit acceptance essential. We have supported businesses of exactly this profile with GSTR-1 & GSTR-3B Monthly Filing across Chepauk for years, along with clients from Triplicane and Chintadripet. 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.
GSTR-1 by the 11th, GSTR-3B by the 20th, CMP-08 by the 18th after each quarter — we maintain a compliance calendar for every client and start chasing your data well before the due date, so late fees never enter the picture.
Composition dealers have their own rulebook — CMP-08 every quarter, GSTR-4 annually by 30 June, bills of supply instead of tax invoices, and a turnover ceiling that must be watched. We handle each of these correctly so the scheme's simplicity never turns into a violation.
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.
Tally, Zoho Books, Busy, marketplace reports, plain Excel or even a handwritten bill book — we take your data in whatever form your Chepauk business already maintains it. You are never forced to buy new software or retrain staff just to become our client.
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.
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.
Amounts deducted by government buyers as GST TDS and by marketplaces as TCS are accepted on the portal each period, so money withheld against your GSTIN actually reaches your cash ledger instead of lying unclaimed.
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.
Your scheme choice — regular, composition or QRMP — is re-examined as turnover and margins change, so you are always paying under the structure that legitimately costs your business the least.
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.
You know your expected GST outflow days before the 20th, not on the night of filing. That advance visibility lets you plan payments, collections and bank balances instead of scrambling for funds at the deadline.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Real notifications, rulings and case law our consultants track — and apply to client filings and notice replies.
Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, Schedule I, renewable energy devices entry · 2025-09-17
Biogas plants, solar power based devices and generators, solar lanterns and lamps, windmills and wind operated electricity generators, waste-to-energy plants, ocean and tidal wave energy devices and photovoltaic cells whether or not assembled into modules or panels are all listed in Schedule I at five per cent from 22 September 2025, reversing the increase made in October 2021. The explanation deeming seventy per cent of a composite project contract to be the value of goods has been carried forward unchanged.
What it means for you: Rooftop solar installers in Chennai bill the goods component at five per cent using the 70:30 split, which materially lowers the delivered cost of a project.
Circular No. 32/06/2018-GST dated 12.02.2018 · 2018-02-12
This early circular resolved several healthcare and accommodation questions. It clarified that room rent charged by a hospital to an in-patient and food supplied to admitted patients as advised by the doctor form part of exempt composite healthcare services, while food sold to attendants and visitors is taxable. It also clarified that where a hospital engages senior consultants and retains a share of their fees, the entire consideration charged to the patient is exempt healthcare service. Separately it dealt with hostel accommodation below the then exemption threshold.
Practical effect: Chennai hospitals should keep patient billing separate from cafeteria and visitor sales, because only the patient-facing package enjoys the healthcare exemption.
29th GST Council Meeting, New Delhi — 4 August 2018 (Signed Minutes, Agenda Item 3) · 2018-08-04
The Council approved a scheme to incentivise digital payment under GST. Concessions were to be given on B2C transactions paid through RuPay debit card, UPI, BHIM, USSD or BHIM-Aadhaar, by way of an automated refund to the consumer's account of twenty per cent of the total GST paid, subject to a ceiling of Rs 100 per transaction shared equally between CGST and SGST. The purchaser would be informed by SMS. The scheme was to run on a pilot basis in Assam, Tamil Nadu and any other volunteering State.
How we apply it: Tamil Nadu was one of only two States selected for this pilot, though the scheme was never rolled out in practice.
