The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Perumbakkam permanently ahead of both, delivering GSTR-1 & GSTR-3B Monthly Filing from Rs.749 with reconciliation, senior review and WhatsApp acknowledgements as standard.
We serve businesses on and around 3rd Street — 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.
Businesses in Perumbakkam looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. Perumbakkam has grown along Semmozhi Salai and Nookampalayam Road, anchored by Gleneagles Global Health City and large gated apartment projects. Builders, interior contractors, diagnostic labs, pharmacies, supermarkets and packers-and-movers dominate the trade here. Developers face the concessional 1 percent and 5 percent housing rates with their domestic procurement condition, alongside reverse charge on unregistered purchases and TDS credit under Section 51. We serve this belt — including Medavakkam and Pallikaranai — with fixed fees quoted upfront, a written document checklist, and filings completed ahead of statutory due dates. Every acknowledgement is shared the day it is generated, and our support continues if the department raises any query on work we have filed.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
Composition dealers have their own rulebook — CMP-08 every quarter, GSTR-4 annually by 30 June, bills of supply instead of tax invoices, and a turnover ceiling that must be watched. We handle each of these correctly so the scheme's simplicity never turns into a violation.
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.
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.
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.
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.
Interest on delayed GST payment runs at 18 percent per annum, which is costlier than most working capital finance. Timely computation and payment through our calendar keeps that meter permanently at zero.
With returns filed ahead of the statutory due dates every period, the Rs.50-per-day GSTR-3B late fee simply stops appearing in your life, and the money stays in your business where it belongs.
When GST knowledge lives inside a single staff member, their resignation becomes a compliance crisis. With our firm as the standing process, your filings continue uninterrupted regardless of internal staff changes.
E-commerce platforms continuously validate seller GSTINs and filing status. A consistently compliant registration keeps your listings active and settlements flowing, with no sudden suspension of your online sales channel.
Your billing staff are guided on invoice fields, rates and series discipline, so mistakes are prevented where they originate — at the counter — instead of being repaired later in the returns.
Loan applications and government tenders routinely demand GST returns and registration documents. With everything filed and archived properly, you can produce a complete compliance file within hours instead of days.
| 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. |
| Due-date tracking | A maintained compliance calendar with internal cut-offs days before the 11th and the 20th; we chase you for data, not the other way around. | Deadlines remembered from memory or phone alarms; one busy week and the return slips past the due date. |
| When a notice arrives | A professional drafts the reply in the department's format and files it within the statutory window, such as thirty days for ASMT-11. | You face departmental language alone, and a missed reply deadline can convert a simple query into a demand with penalty. |
| 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. |
| 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. |
3rd Street is a residential street in Perumbakkam, about 650 m north-west of the centre of Perumbakkam. The same consultant covers the streets immediately around it — Sowmya Nagar 2nd Main Road (about 50 m); Sowmiya Nagar 1st Main Road (about 50 m); 5th Main Road (about 100 m); Rajiv Gandhi 2nd Street (about 150 m) — so a site visit on 3rd Street can usually be combined with other work in Perumbakkam on the same trip. For GST purposes an address on 3rd Street falls under the Chennai South CGST Commissionerate, and the Perumbakkam pincode is 600100.

GSTN Advisory, November 2023 — two-factor authentication for logging into the GST portal · 2023-11
GSTN introduced two-factor authentication for the GST portal. Besides the user identity and password, a one-time password is delivered to the primary authorised signatory's registered mobile number and e-mail address, and must be entered to complete login. The measure was piloted in selected states and then extended in phases across the country, covering taxpayers as well as their sub-users. Login fails if the registered contact details on the portal are outdated and the one-time password cannot be received.
What to do about it: Keep the authorised signatory's mobile number and e-mail current on the portal, otherwise your team can be locked out on the filing due date.
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.
M/s. Ajay Agency v. State Tax Officer — Madras High Court, W.P. No. 8507 of 2023, decided 30 March 2023 (Anita Sumanth J.) · 2023-03-30
A consignment of power weeders was intercepted on 6 March 2023 at about 10.30 a.m., the e-way bill having expired at 11.59 p.m. the previous night. The taxpayer pleaded a vehicle breakdown. The Court declined to interfere, noting that the validity could have been extended within the permitted window and had not been, and that the officer's decision to detain and penalise under Section 129(1) was not unreasonable. The writ petition was dismissed with liberty to file a statutory appeal.
What to do about it: Chennai transporters must extend e-way bill validity within the permitted window when a vehicle breaks down; the High Court will not excuse an expired bill merely because of a breakdown.
