Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Late fees, blocked credit and mismatch notices cost far more than professional help ever will. We complete GSTR-1 & GSTR-3B Monthly Filing for Mogappair businesses from Rs.749, matching every figure against portal data before anything reaches the department.
We serve businesses on and around Gangai Amman Nagar — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

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. When businesses of this kind evaluate GSTR-1 & GSTR-3B Monthly Filing, the real question is not price alone but who answers when something goes wrong. We serve Mogappair, Ambattur and Anna Nagar on a standing commitment: responses within the same working day, senior scrutiny before every submission, and continued support if the department ever writes back on work carrying our preparation.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
If your GSTR-1 and GSTR-3B start drifting apart, if a large supplier stops filing, or if your turnover approaches the e-invoice threshold, we flag it to you immediately. Early warnings from our side are cheaper than departmental letters later.
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.
If a query, ASMT-10 scrutiny notice or DRC-01 arrives on a return we filed, we stand behind our work and help you draft the reply. You are not left alone with a departmental letter and a thirty-day clock ticking against you.
When an ADT-01 audit intimation or a personal hearing date arrives, we compile the records, prepare the reconciliations and draft the submissions, and coordinate closely with your authorised representative. You walk into the proceeding prepared, not improvising in front of an officer.
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.
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 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.
A fixed professional fee is almost always cheaper than the combination of late fees, interest, lost credit and staff hours that informal, last-minute compliance quietly accumulates over a year.
Illness, travel or a family function no longer threatens a deadline. With a standing external process holding your calendar and data trail, filings proceed on schedule whether or not you are at your desk.
Late-fee waivers and amnesty windows notified by the GST Council are applied to your history within their deadlines, capturing reliefs that most businesses only hear about once the window has already closed.
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 |
|---|---|---|
| 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. |
| 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. |
| Input tax credit | Purchase register matched against GSTR-2B each period, with defaulting suppliers chased so eligible credit is actually captured. | Credit claimed from books alone; mismatches with GSTR-2B mean lost credit or excess claims that invite departmental queries. |
| 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. |
| 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. |
| 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. |
Positions we rely on when preparing filings and drafting replies — with the exact citation, so you can verify each one.
GSTN Advisories No. 624 dated 27 September 2025 and No. 631 dated 17 October 2025 — IMS enhancements from the October 2025 tax period · 2025-10
GSTN enhanced the Invoice Management System from the October 2025 tax period. Recipients can now keep credit notes and specified records pending for one tax period instead of being forced to accept or reject them immediately, can declare the actual amount of input tax credit to be reduced when accepting a credit note where the credit was never availed or was already reversed, and can save remarks when rejecting or keeping a document pending. GSTR-2B can be recomputed after corrective action is taken.
Practical effect: Train your accounts team on the new pending and partial-reversal options so supplier credit notes do not strip more ITC than legally required.
Circular No. 203/15/2023-GST · 2023-10-27
CBIC clarified three recurring place-of-supply questions. For transportation of goods, including by mail or courier, where the supplier or the recipient is outside India, Section 13(9) of the IGST Act stood omitted from 1 October 2023, so the place of supply is now fixed by the default rule in Section 13(2), namely the location of the recipient. For advertising services supplied to a government body, the place of supply follows the location of the recipient under Section 12(2) rather than the location of the hoardings, with State-wise allocation where the contract provides for it. For co-location of servers in a data centre, the supply is a bundle of hosting services and not a letting of immovable property, so the recipient's location governs.
How we apply it: Chennai courier, advertising and data centre businesses should map their invoices to these tests before deciding between IGST and CGST plus SGST.
34th GST Council Meeting (video conferencing) — 19 March 2019 · 2019-03-19
The Council gave promoters a one-time option to continue paying tax at the old effective rates of eight or twelve per cent with input tax credit on ongoing projects, meaning buildings where both construction and actual booking had started before 1 April 2019 and which were not completed by 31 March 2019. The option had to be exercised once within a prescribed time frame, failing which the new rates applied automatically. Credit for projects moving across was to be transitioned pro rata.
What it means for you: Chennai builders who did not formally exercise the option in 2019 are on the one and five per cent no-credit rates, and any credit claimed since then is exposed to reversal.
