T. Nagar is South India's densest retail market, from silk showrooms on Usman Road to jewellery flagships around Panagal Park and garment stalls on Ranganathan Street. Turnover crosses the Rs.5 crore e-invoice threshold quickly here, and high-volume B2C billing produces chronic GSTR-1 versus GSTR-3B gaps, branch stock-transfer questions and close scrutiny of jewellers' HSN-wise reporting. Years of working in and around T. Nagar have shown us where GST trouble actually begins here — supplier defaults, classification doubts and deadlines lost in busy trading weeks. Our GSTR-1 & GSTR-3B Monthly Filing is built to close precisely those gaps, and the same team supports businesses in West Mambalam and Nungambakkam, each with one point of contact and a compliance calendar maintained on their behalf.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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.
Every acknowledgement, challan, computation sheet and filed return is saved and shared with you in an organised folder. When a bank, buyer or GST officer asks for a document from two years ago, it reaches you the same day without any scrambling.
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.
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 T. Nagar business supplies, the rate, classification and place-of-supply questions have almost certainly crossed our desk before.
Your work is executed by trained GST staff working under direct senior supervision, not passed to interns learning on your file. The person preparing your return understands reverse charge, blocked credits and place of supply, because getting these wrong costs you money.
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.
New branches, new product lines and interstate sales all carry GST consequences. With standing professional support, you expand knowing registrations, invoicing and returns will keep pace with the business.
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.
Each period you receive a simple computation showing output tax, credit utilised and net cash payable, so GST becomes a number you understand and question rather than a figure you accept blindly.
Whether moving between composition and regular scheme, opting into QRMP, or crossing the e-invoice threshold at Rs.5 crore, transitions are planned in advance rather than discovered after a compliance breach.
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.
Tax positions, rate choices and credit calls are documented as they are made, so if a question arises years later, the reasoning and evidence are on file rather than in someone's fading memory.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |

42nd GST Council Meeting (video conferencing) — 5 October 2020 · 2020-10-05
The Council approved what became the Quarterly Return Monthly Payment scheme. Registered persons with aggregate annual turnover up to Rs 5 crore were allowed to furnish GSTR-3B on a quarterly basis from 1 January 2021, while paying tax monthly through a challan. The due date for the quarterly GSTR-1 was fixed at the 13th of the month following the quarter, and an invoice furnishing facility was provided so that recipients could still see credit monthly. This remains the default compliance route for most small businesses.
What it means for you: A Chennai business under Rs 5 crore can file GSTR-3B four times a year instead of twelve, but must still deposit tax every month, and missing that monthly challan attracts interest.
Notification No. 18/2022-Central Tax · 2022-09-28
This notification brought most of the Finance Act, 2022 amendments into force from 1 October 2022. Section 16(4) was amended so that input tax credit for a financial year can be claimed up to 30 November of the following year instead of the due date of the September return. The same deadline now applies to issuing credit notes under Section 34 and to rectifying errors in GSTR-1 and GSTR-3B. Section 41 was also substituted to remove provisional credit and sequential filing of returns was mandated.
Practical effect: A Chennai business gets until 30 November to pick up missed credit and to issue credit notes for the previous year, which is the single most important annual deadline after the returns themselves.
Circular No. 149/05/2021-GST dated 17.06.2021 · 2021-06-17
CBIC clarified that serving food in schools under the mid-day meal programme is exempt from GST, and that the exemption extends to pre-schools and anganwadis, which are covered within the meaning of an educational institution providing pre-school education. It further clarified that the exemption applies whether the meals are funded by government grants or by corporate donations, since the entry does not distinguish by source of funding. The clarification protected non-profit caterers running school feeding programmes from demands.
Why this matters: Chennai caterers running school or anganwadi meal contracts are exempt, but should keep the scheme documentation on file to answer any scrutiny.
