Nandambakkam, on Mount-Poonamallee Road beside the Adyar river, is defined by the Chennai Trade Centre exhibition complex and the Officers Training Academy belt near St. Thomas Mount. Exhibition organisers, stall fabricators, caterers and AV rental firms work event cycles here, wrestling with 18 per cent GST on stall licensing, place-of-supply rules for out-of-state exhibitors and input tax credit on temporary structures. We have supported businesses of exactly this profile with GSTR-1 & GSTR-3B Monthly Filing across Nandambakkam for years, along with clients from St. Thomas Mount and Guindy. 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.
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.
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.
You deal with one accountable person who knows your business, your turnover pattern and your filing history. No repeating your story to a new voice every month, and no file falling between two desks when a deadline is approaching.
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.
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 Nandambakkam never writes back to you as a demand years later.
Sellers on Amazon, Flipkart and other marketplaces face a three-way match between marketplace reports, GSTR-1 and the TCS the operator deposits against your GSTIN. We reconcile all three every period and accept the TCS credit, so sellers in Nandambakkam never leave marketplace deductions unclaimed.
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.
Where a genuine error is found in a past period, voluntary payment through DRC-03 before any notice issues closes the matter at minimal cost, instead of letting it ripen into a demand with penalty.
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.
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.
Large buyers check vendor GST compliance before releasing payments and renewing contracts. A clean filing record with timely GSTR-1 uploads keeps your invoices reflecting in their GSTR-2B and your payments unblocked.
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.
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. |
| 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. |
| 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. |
2nd Cross is a residential street in Nandambakkam, about 600 m west of the centre of Nandambakkam. The same consultant covers the streets immediately around it — 1st Cross (about 0 m); 3rd Cross (about 0 m); 4th Cross (about 50 m); 5th Cross (about 50 m) — so a site visit on 2nd Cross can usually be combined with other work in Nandambakkam on the same trip. For GST purposes an address on 2nd Cross falls under the Chennai South CGST Commissionerate, and the Nandambakkam pincode is 600089.

GSTN Advisories dated 11 April 2025 and 16 May 2025 — Table 3.2 of GSTR-3B · 2025-04-11
GSTN first advised that from the April 2025 period, auto-populated values in Table 3.2 of GSTR-3B, covering inter-state supplies to unregistered persons, composition taxpayers and UIN holders, would become non-editable, with corrections routed through GSTR-1A. After taxpayer representations, a 16 May 2025 advisory kept Table 3.2 editable for the time being. The locking was later subsumed in the broader hard-locking of GSTR-3B liability during 2025.
How we apply it: Report place-of-supply details correctly in GSTR-1 itself, since state-wise B2C figures in GSTR-3B are moving beyond manual correction.
Notification No. 22/2019-Central Tax dated 23.04.2019 · 2019-04-23
This notification appointed a date for rule 138E of the CGST Rules to come into force. Rule 138E bars generation of Part A of the e-way bill in respect of a registered person who has not furnished returns for two consecutive tax periods, or, in the case of a composition taxpayer, for two consecutive quarters. The commencement date was subsequently deferred more than once before the blocking facility was actually activated on the portal.
Why this matters: A Chennai business that falls two return periods behind will find e-way bill generation blocked, which halts dispatches until the pending returns are filed.
Krishna Bhavan Foods and Sweets - AAR Tamil Nadu, Order No. TN/24/AAR/2021, dated 18 June 2021, upheld by AAAR Tamil Nadu, Order No. TN/AAAR/02/2022, dated 13 January 2022 · 2021-06-18
The applicant sold packaged ready to cook instant mixes for dosai, idli, tiffin items, sweets, health mix and porridge. It argued that these were only flours of cereals and pulses taxable at 5 percent. The Authority classified the products under heading 2106 90 as food preparations not elsewhere specified, attracting 18 percent GST, because the mixing and added ingredients took them out of the concessional flour entries. The Appellate Authority upheld that classification.
How we apply it: Chennai food manufacturers selling instant mixes should confirm whether the product is a plain flour or a preparation before applying 5 percent.
