Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
GSTR-1 & GSTR-3B Monthly Filing in T. Nagar does not have to mean portal errors, guesswork and due-date tension. For a fixed fee starting Rs.749, an accountable Chennai practice prepares, reconciles, reviews and files — and remains answerable long after the acknowledgement arrives.
We serve businesses on and around Ramanathan Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

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. We have supported businesses of exactly this profile with GSTR-1 & GSTR-3B Monthly Filing across T. Nagar for years, along with clients from West Mambalam and Nungambakkam. 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.
Goods sent to job workers must move on delivery challans, return within the statutory period, and be reported in ITC-04. We track every outward and return leg for manufacturing clients in T. Nagar, so inputs sent out for processing never quietly convert into a deemed supply carrying tax and interest.
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.
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.
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.
No filing leaves our desk on a junior's judgement alone. A senior GST practitioner reviews your figures, ITC claims and tax computation before submission, so errors are caught at our table and not by the department months later through a notice.
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.
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.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
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.
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.
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.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Ramanathan Street is a residential street in T. Nagar, about 650 m south-west of the centre of T. Nagar. The same consultant covers the streets immediately around it — Ranganathan Street (about 100 m); South Usman Road (about 150 m); Sarojini Street (about 300 m); Madley Road (about 300 m) — so a site visit on Ramanathan Street can usually be combined with other work in T. Nagar on the same trip. For GST purposes an address on Ramanathan Street falls under the Chennai South CGST Commissionerate, and the T. Nagar pincode is 600017.

WABCO India Ltd - AAR Tamil Nadu, Order No. TN/10/AAR/2018, dated 27 September 2018 · 2018-09-27
The manufacturer supplied electrical wiring harness, essentially electrical wire with connectors at both ends, used in motor vehicles, and asked whether it should be classified as a motor vehicle part or as insulated electrical conductors. The Authority classified the product under heading 8544, which covers insulated wire and cable fitted with connectors, taxable at 9 percent central tax and 9 percent State tax following Notification No. 41/2017-Central Tax (Rate) dated 14 November 2017, the earlier rate having been higher.
Why this matters: Chennai auto component makers should classify by the tariff description of the article itself, not by the vehicle it eventually goes into.
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.
Why this matters: Report place-of-supply details correctly in GSTR-1 itself, since state-wise B2C figures in GSTR-3B are moving beyond manual correction.
Circular No. 136/06/2020-GST dated 3 April 2020 · 2020-04-03
CBIC explained the relief notified through Notifications 30 to 36 of 2020-Central Tax after the first lockdown. It set out, return by return and class by class, the extended dates for GSTR-3B and GSTR-1, the conditional waiver of interest for the tax periods February to April 2020 with nil interest for the first fifteen days and nine per cent thereafter for larger taxpayers, the waiver of late fee, the relaxation of the rule 36(4) credit restriction, and the extension for composition taxpayers.
Why this matters: Interest and late fee demands for the early 2020 periods must be tested against these concessional rates before they are paid.
