Finding dependable GSTR-1 & GSTR-3B Monthly Filing in Koyambedu usually means choosing between a distant online portal and an overloaded local accountant. Koyambedu hosts one of Asia's largest perishables markets, the Koyambedu Wholesale Market Complex, and the CMBT bus terminus, driving trade by vegetable and fruit wholesalers, flower merchants, commission agents and transporters. Fresh produce is largely exempt while packaged and labelled goods are taxable, so mixed supplies, commission income, GTA reverse charge and e-way bills for outstation consignments dominate compliance here. We offer a third option: a professional Chennai GST practice that treats Koyambedu, Arumbakkam and Anna Nagar as home ground, responds the same working day, files ahead of deadlines, and stands behind its work if a notice ever arrives on a return we prepared.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
A new GSTIN comes with obligations nobody explains at approval — the invoice series rules, displaying the registration certificate and GSTIN at your premises, and the first return cycle. We walk new registrants in Koyambedu through each of these so month one starts correctly.
Tally, Zoho Books, Busy, marketplace reports, plain Excel or even a handwritten bill book — we take your data in whatever form your Koyambedu business already maintains it. You are never forced to buy new software or retrain staff just to become our client.
You are told the full fee before we begin, in writing. No surprise additions for uploads, revisions or acknowledgements. Government fees and taxes, where applicable, are shown separately, so businesses in Koyambedu always know exactly what the engagement costs them.
A registration cancelled for non-filing is not the end of the road. We bring the pending returns up to date, clear the dues and file the revocation application in REG-21 within the permitted window, restoring suspended and cancelled GSTINs to active status.
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.
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.
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.
Because turnover in your GST returns is kept aligned with your accounts through the year, income tax filing and statutory audit proceed without the GST-versus-books mismatch queries that now surface routinely through data matching.
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.
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.
Because monthly data is reconciled as it happens, GSTR-9 preparation before the 31 December due date becomes a review exercise rather than a painful reconstruction of twelve untidy months.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
Positions we rely on when preparing filings and drafting replies — with the exact citation, so you can verify each one.
GSTN Advisory dated 14 November 2023 — input tax credit reversal under Rule 37A of the CGST Rules for FY 2022-23 · 2023-11-14
Rule 37A requires a buyer to reverse input tax credit where the supplier reported the invoice in GSTR-1 but did not file the GSTR-3B for that tax period by 30 September following the end of the financial year. The reversal must be made in the GSTR-3B filed on or before 30 November. GSTN made supplier-wise details of such invoices available on the portal and advised taxpayers to complete the reversal for FY 2022-23 by 30 November 2023. The credit can be reclaimed once the supplier files the pending return.
What it means for you: Run a supplier compliance check every October, because credit from a defaulting supplier must be reversed by 30 November or carries interest.
39th GST Council Meeting, New Delhi — 14 March 2020 · 2020-03-14
Following widespread demands computing interest on the gross tax liability of a late GSTR-3B, ignoring the credit balance available, the Council recommended that interest under Section 50 be charged only on the net cash tax liability, with retrospective effect from 1 July 2017. This was given effect through the proviso to Section 50(1) inserted by the Finance Act, 2021 and notified retrospectively, and it neutralised thousands of interest demands raised on gross turnover across the country.
What to do about it: If you have received an interest demand computed on gross output tax for a late return, the net cash liability principle from this meeting is usually a complete answer.
Notification No. 55/2023-Central Tax · 2023-12-20
After Cyclone Michaung caused severe flooding in and around Chennai, CBIC extended the due date for furnishing Form GSTR-3B for the tax period November 2023 to 27 December 2023 for registered persons whose principal place of business falls in the districts of Chennai, Tiruvallur, Chengalpattu and Kancheepuram in Tamil Nadu. The relief applied automatically by district and no separate application was required from affected taxpayers.
What to do about it: In a declared local disaster, CBIC does grant district-specific extensions for Chennai, so check for a notification before paying late fee on a delayed return.
