Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Whether you are a first-time registrant or an established trader, GSTR-1 & GSTR-3B Monthly Filing in Iyyappanthangal deserves a specialist rather than a side job. From Rs.749, our GST-focused Chennai practice runs the entire process on written checklists and senior-reviewed submissions.
We serve businesses on and around Kamaraj Nagar — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.
Share your number — a senior GST consultant calls you back within 30 minutes.
GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Iyyappanthangal sits on Mount Poonamallee Road beside its MTC bus depot, in the hospital shadow of the Porur medical belt, with pharmacies, diagnostic collection centres, supermarkets and apartment builders filling the frontage towards Kattupakkam and Mangadu. Builders selling under-construction flats at the 1 and 5 per cent rates without input tax credit, and pharmacies handling 5, 12 and 18 per cent medicine slabs, drive most GST queries. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Iyyappanthangal follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Porur and Kattupakkam run on the same process, entirely over WhatsApp if they prefer.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Iyyappanthangal. We know how local proper officers examine registrations, what supporting documents they routinely call for, and how to present a file so it moves without repeated queries.
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.
OTP failures, DSC errors, stuck submissions on due-date evenings — we deal with the GST portal daily and know the workarounds. When the site misbehaves on the 20th, our team keeps retrying and escalating so your return still goes through.
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.
Your cash ledger, credit ledger and liability register are reviewed regularly, not just at filing time. Excess balances are flagged for use or refund, and where a genuine slip surfaces, a voluntary payment through DRC-03 settles it before it can mature into a notice.
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 Iyyappanthangal always know exactly what the engagement costs them.
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.
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.
Your scheme choice — regular, composition or QRMP — is re-examined as turnover and margins change, so you are always paying under the structure that legitimately costs your business the least.
The hours you or your accountant spent wrestling with the portal, JSON errors and reconciliations every month return to sales, operations and customers, while trained hands manage the compliance in the background.
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.
Sales returns, discounts and price revisions are adjusted through properly reported credit notes within the statutory window, so you never keep paying tax on turnover you have already reversed.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Positions we rely on when preparing filings and drafting replies — with the exact citation, so you can verify each one.
23rd GST Council Meeting, Guwahati — 10 November 2017 (PIB Release ID 1509037) · 2017-11-10
The Council recommended reducing the GST rate from 28 to 18 per cent on goods falling in 178 headings at the four-digit level, including four headings only partially pruned, so that the 28 per cent list fell from 224 tariff headings to only about 50. Further reductions were recommended from 28 to 12 per cent, from 18 to 12 per cent and from 18 to 5 per cent on specified goods, together with relief for the aviation and handicraft sectors and restaurants.
What to do about it: This is the single largest rate rationalisation of the early GST years and reset the price and credit position for most Chennai consumer goods dealers overnight.
GSTN Advisory dated 7 June 2025 — barring of GST returns after three years (Finance Act, 2023; Notification No. 28/2023-Central Tax) · 2025-06-07
Implementing the Finance Act, 2023 amendments to Sections 37, 39, 44 and 52, notified by Notification No. 28/2023-Central Tax, GSTN advised that from the July 2025 tax period the portal blocks filing of GST returns once three years have passed from their due date. The bar covers GSTR-1, GSTR-1A, GSTR-3B, GSTR-4, GSTR-5, GSTR-5A, GSTR-6, GSTR-7, GSTR-8 and GSTR-9. Taxpayers with old pending returns were urged to reconcile their records and file before the returns became permanently time-barred on the portal.
Practical effect: Clear every pending old return now, because once the three-year window closes the portal will not accept the return and registration consequences follow.
Megha Engineering and Infrastructures Ltd v. Commissioner of Central Tax — Telangana High Court, judgment dated 18 April 2019 · 2019-04-18
The taxpayer filed GSTR-3B late and paid interest only on the net cash portion of the tax. The High Court held that on the language of Section 50 as it then stood, interest ran on the gross liability, because input tax credit is credited to the ledger only when the return is filed. The decision caused wide concern in trade, and Parliament later amended Section 50 with retrospective effect from 1 July 2017 to charge interest only on the cash component in most late-return cases.
Practical effect: For late returns, interest is now generally computed on the cash portion only — if an older notice demands interest on gross tax, rely on the retrospective proviso to Section 50.
