Choosing GSTR-1 & GSTR-3B Monthly Filing in Thirumangalam is ultimately an act of trust: you are handing over sales figures, purchase records and portal access. Thirumangalam junction, where Jawaharlal Nehru Salai meets Anna Nagar 2nd Avenue beside the metro station and VR Chennai mall, has become a showroom strip for jewellery, textiles, furniture and electronics chains spilling into Anna Nagar West Extension. High-volume B2C billing with occasional B2B orders makes correct GSTR-1 bifurcation and e-invoice applicability checks the daily compliance concern for retailers here. We earn that trust the unglamorous way — fixed fees honoured, drafts approved by you before filing, acknowledgements shared the same day, and strict confidentiality throughout. Clients across Thirumangalam, Anna Nagar and Mogappair have stayed with us for years on precisely this basis.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
Most GST notices trace back to mismatches between GSTR-1, GSTR-3B and GSTR-2B. We reconcile these before filing, not after a notice arrives, so your returns are internally consistent and the most common triggers for ASMT-10 scrutiny simply never appear.
Every new client receives a review of their recent returns before we file anything — unclaimed credit, GSTR-1 versus GSTR-3B drift, and exposures worth correcting quietly. Businesses in Thirumangalam often discover in this first review exactly why their previous arrangement was costing them money.
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 Thirumangalam through each of these so month one starts correctly.
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.
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.
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.
Systematic GSTR-2B matching and supplier follow-up mean input tax credit that was leaking away under self-filing is captured each month, directly reducing the cash you pay out with every GSTR-3B.
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.
Getting IGST versus CGST and SGST right at the invoice stage spares you the painful cycle of paying the correct head again and pursuing a refund of the amount paid under the wrong one.
Advances received for services attract GST on receipt while advances for goods generally do not; applying this distinction correctly means you neither prepay tax unnecessarily nor omit a liability that surfaces later with interest.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Periyar Street is a residential street in Thirumangalam, about 1.7 km west of the centre of Thirumangalam. The same consultant covers the streets immediately around it — Ambedkar Street (about 800 m); V.O.C. Street (about 800 m); Anna Street (about 900 m); Rajaji Street (about 1.0 km) — so a site visit on Periyar Street can usually be combined with other work in Thirumangalam on the same trip. For GST purposes an address on Periyar Street falls under the Chennai North CGST Commissionerate, and the Thirumangalam pincode is 600040.

Commissioner of Customs and Central Excise v. Hongo India (P) Ltd — Supreme Court, (2009) 5 SCC 791, judgment dated 27-03-2009 · 2009-03-27
The Supreme Court held that where a special taxing statute provides a complete code with its own limitation scheme, the general provisions of the Limitation Act permitting condonation of delay do not apply. Delay in filing a reference or appeal beyond the period prescribed by the special statute cannot be condoned. The scheme, language and object of the special Act determine whether the Limitation Act is impliedly excluded.
What it means for you: Chennai businesses must treat GST appeal and revision deadlines as absolute, since general limitation relief is not available.
13th GST Council Meeting, New Delhi — 31 March 2017 (Signed Minutes, Agenda Items 2 and 3) · 2017-03-31
The Council approved in principle four draft GST Rules covering Input Tax Credit, Valuation, Transitional Provisions and Composition, and approved the amended versions of five rules already cleared earlier, namely Registration, Return, Payment, Refund, and Invoice and Debit or Credit Note. The rules were to be circulated to the States and placed in the public domain for comment before final approval, which is how the CGST Rules, 2017 took the shape businesses work with today.
How we apply it: The invoicing, credit and refund procedures a Chennai business follows are governed by rules whose architecture was settled at this single meeting.
Entry 4, Notification No. 13/2017-Central Tax (Rate) dated 28.06.2017 · 2017-06-28
Sponsorship services supplied by any person to a body corporate or partnership firm located in the taxable territory were placed under reverse charge, so the sponsor paying for naming rights, event branding or team sponsorship had to discharge the tax. The entry has since been narrowed: on the recommendation of the GST Council at its 55th meeting, sponsorship services supplied by body corporates were moved to forward charge, leaving reverse charge to apply mainly where the sponsorship provider is not a body corporate.
How we apply it: A Chennai company sponsoring a sports event or cultural programme must check whether the organiser is a body corporate before deciding to pay under reverse charge or accept a tax-charged invoice.
