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. Years of working in and around Thirumangalam have shown us where GST trouble actually begins here — supplier defaults, classification doubts and deadlines lost in busy trading weeks. Our GSTR-1 & GSTR-3B Monthly Filing is built to close precisely those gaps, and the same team supports businesses in Anna Nagar and Mogappair, each with one point of contact and a compliance calendar maintained on their behalf.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
If a query, ASMT-10 scrutiny notice or DRC-01 arrives on a return we filed, we stand behind our work and help you draft the reply. You are not left alone with a departmental letter and a thirty-day clock ticking against you.
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.
New GSTIN applications, core field amendments through REG-14, additional places of business — we prepare complete, query-resistant applications the first time. Clean paperwork is the difference between smooth approval and weeks lost answering clarification memos from the department.
Quarterly filing still demands monthly attention — IFF uploads so your buyers see their credit on time, and tax payment through PMT-06 by the 25th for the first two months of each quarter. We run that monthly rhythm so QRMP saves you effort without creating gaps.
GSTR-3B late fees run at Rs.50 per day and interest at 18 percent per annum on unpaid tax. Our internal cut-offs sit days ahead of statutory due dates precisely so that our clients never hand the department a rupee they did not owe.
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.
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.
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.
Rates, reverse charge, place of supply and blocked credits are applied correctly at the preparation stage, so you neither overpay tax you do not owe nor underpay and invite demands with penalty later.
Where a genuine error is found in a past period, voluntary payment through DRC-03 before any notice issues closes the matter at minimal cost, instead of letting it ripen into a demand with penalty.
With the LUT filed at the start of each financial year and refund claims tracked to credit, exporters supply without blocking funds in IGST and recover accumulated credit on schedule.
Correct, complete tax invoices signal a well-run business to customers, vendors and banks alike, quietly strengthening your credibility in every transaction where your paperwork is seen.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| Goods in transit | E-way bills generated correctly and matched to invoices, so consignments pass roadside inspections without detention or penalty. | A defective or missing e-way bill can mean detention at a checkpoint, with penalties that dwarf the tax on the consignment. |
| 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. |
19th Street is a residential street in Thirumangalam, about 300 m north of the centre of Thirumangalam. The same consultant covers the streets immediately around it — 12th Street (about 150 m); 16th Street (about 200 m); 10th Street (about 300 m); School Road (about 300 m) — so a site visit on 19th Street can usually be combined with other work in Thirumangalam on the same trip. For GST purposes an address on 19th Street falls under the Chennai North CGST Commissionerate, and the Thirumangalam pincode is 600040.

Rotary Club of Mumbai Queens Necklace — AAAR Maharashtra (2019), on appeal from AAR Maharashtra, Advance Ruling No. GST-ARA-118/2018-19 · 2019
The club collected membership subscriptions and admission fees which were spent on meetings, administration and communication, with no facility or benefit supplied to members in return. The Maharashtra Appellate Authority for Advance Ruling held that the collections merely defray shared expenses, that there is no supply of goods or services to members, and that the amounts are therefore not consideration liable to tax.
What it means for you: Chennai associations should note that Section 7(1)(aa), inserted with retrospective effect from 1 July 2017, now treats club to member supplies as taxable, so this reasoning no longer holds.
RSB Transmissions (India) Ltd v. Union of India — Jharkhand High Court, judgment dated 18 October 2022 · 2022-10-18
The taxpayer had deposited about Rs. 29.83 crore into the electronic cash ledger before the due dates but filed GSTR-3B late for several tax periods between July 2017 and December 2019, and interest was demanded for the delay. The High Court dismissed the challenge, holding that a deposit in the electronic cash ledger is only money held to the taxpayer's credit and does not discharge tax liability. Liability is discharged only when the ledger is debited on filing the return, so interest runs until then.
How we apply it: Depositing cash into the ledger early does not protect you from interest — the GSTR-3B must actually be filed on time.
Notification No. 1/2025-Central Tax (Rate), dated 16 January 2025 · 2025-01-16
Following the 55th GST Council meeting, fortified rice kernel classifiable under heading 1904 was placed at five per cent irrespective of end use, removing the earlier distinction based on whether it was supplied for public distribution. The same notification recast the definition of pre-packaged and labelled so that it clearly covers commodities intended for retail sale in packs of not more than twenty-five kilograms or twenty-five litres that must bear declarations under the Legal Metrology Act, 2009.
Why this matters: Rice millers and food processors supplying fortified rice kernel charge five per cent from 16 January 2025 whoever the buyer is.
