Mogappair, officially Dr. J.J. Nagar, is a healthcare and residential hub where the Madras Medical Mission hospital, multi-speciality clinics, diagnostic labs and pharmacies line Ambattur Industrial Estate Road and the East and West blocks. Hospitals and clinics supplying exempt healthcare alongside taxable pharmacy and canteen sales must apportion input tax credit between the two, the locality's most frequent GST question. 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 Mogappair and neighbouring Ambattur and Anna Nagar, 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.
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.
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.
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.
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 Mogappair never writes back to you as a demand years later.
Your cash ledger, credit ledger and liability register are reviewed regularly, not just at filing time. Excess balances are flagged for use or refund, and where a genuine slip surfaces, a voluntary payment through DRC-03 settles it before it can mature into a notice.
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.
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.
Consistent, reconciled returns give the department's matching systems nothing to flag. Clients who move to us after years of self-filing typically see scrutiny queries and mismatch notices fall away within a few filing cycles.
With returns filed ahead of the statutory due dates every period, the Rs.50-per-day GSTR-3B late fee simply stops appearing in your life, and the money stays in your business where it belongs.
We spot suppliers who stop uploading invoices or filing returns and alert you before their default becomes your blocked credit, letting you recover amounts or switch vendors while the exposure is still small.
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.
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.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| Late fees and interest | Filings go in ahead of statutory dates, so the Rs.50-per-day late fee and 18 percent interest never arise. | Late fees accumulate silently every delayed day, and interest on unpaid tax runs at 18 percent per annum. |
| 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. |
| 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. |
| Record keeping | Every return, challan, acknowledgement and working paper archived in an organised folder, retrievable in minutes years later. | Documents scattered across email, downloads and old phones; assembling records for a bank or an audit takes days. |
GST law moves through notifications, circulars and court decisions. These are the ones changing how filings are prepared right now.
TVH Lumbini Square Owners Association - AAR Tamil Nadu, Order No. 25/ARA/2019, dated 21 June 2019 · 2019-06-21
A residents welfare association collected monthly maintenance contributions from its members. The Authority held that where the contribution per member exceeds Rs. 7,500 a month, GST is payable on the entire contribution and not merely on the amount above Rs. 7,500. The Madras High Court subsequently held, in Greenwood Owners Association, that only the excess over Rs. 7,500 is taxable, and associations now follow that judicial position.
What to do about it: Chennai apartment associations should apply the High Court position carefully and keep member-wise workings ready for departmental scrutiny.
GSTN Advisory dated 14 November 2023 — Form GST DRC-01C under Rule 88D of the CGST Rules · 2023-11-14
Where the input tax credit availed in GSTR-3B exceeds the credit available in GSTR-2B by more than the prescribed limit, the portal issues an intimation in Form GST DRC-01C. The taxpayer must reverse the excess with interest through DRC-03 or file a reply in Part B giving reasons, within seven days. If neither is done, the filing of the next GSTR-1 or Invoice Furnishing Facility statement is blocked.
How we apply it: Match your credit register against GSTR-2B before filing GSTR-3B, since an unexplained excess now stops your outward return.
Notification No. 01/2017-Central Tax dated 19.06.2017 · 2017-06-19
This was the first notification issued under the CGST Act. It appointed 22 June 2017 as the date on which the preliminary and registration provisions came into force, including sections 1 to 5, section 10 (composition levy) and sections 22 to 30, which deal with who must register, compulsory registration, the procedure for registration, amendment of registration and cancellation. It opened the GST registration window before the tax itself became payable.
How we apply it: Every Chennai registration granted on or after 22 June 2017 traces its legal authority to this notification, so registration certificates dated from that day are validly issued.
