Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
GSTR-1 & GSTR-3B Monthly Filing in West Mambalam does not have to mean portal errors, guesswork and due-date tension. For a fixed fee starting Rs.749, an accountable Chennai practice prepares, reconciles, reviews and files — and remains answerable long after the acknowledgement arrives.
We serve businesses on and around Panneerselvam 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.
West Mambalam packs caterers, flower and pooja goods sellers, tailoring units and tuition centres into dense streets like Lake View Road and Arya Gowda Road beside Mambalam railway station. Family-run businesses here often operate near the Rs.40 lakh goods and Rs.20 lakh services registration thresholds, so registration timing, composition eligibility and purchases from unregistered dealers are the common questions. That commercial character shapes the GST questions we see from West Mambalam every week — registrations, monthly returns, credit mismatches and departmental queries. We deliver GSTR-1 & GSTR-3B Monthly Filing for businesses in West Mambalam, and clients also reach us from T. Nagar and Ashok Nagar nearby. Documents move over WhatsApp, drafts are approved before filing, and a senior consultant reviews every submission, so distance from our office never dilutes the quality of the work.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering West Mambalam. 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.
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.
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.
Sellers on Amazon, Flipkart and other marketplaces face a three-way match between marketplace reports, GSTR-1 and the TCS the operator deposits against your GSTIN. We reconcile all three every period and accept the TCS credit, so sellers in West Mambalam never leave marketplace deductions unclaimed.
Businesses with registrations in more than one State, or multiple branches under one PAN, face cross-charge, stock transfer and input service distribution questions that single-GSTIN firms never see. We keep all your registrations consistent with each other, not just compliant individually.
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.
When a query or verification comes, you respond through a professional who deals with the department regularly, in the department's own language and format, instead of facing an officer's letter alone.
Correct e-way bills matched to correct invoices mean your consignments clear roadside inspections cleanly, avoiding detention proceedings whose penalties can far exceed the tax on the goods being carried.
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.
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.
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.
Whether moving between composition and regular scheme, opting into QRMP, or crossing the e-invoice threshold at Rs.5 crore, transitions are planned in advance rather than discovered after a compliance breach.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
We track every notification, circular and judgment that changes a filing position, so your returns and replies reflect the current law.
The Bank of Nova Scotia - AAR Tamil Nadu, Order No. TN/23/AAR/2018, dated 31 December 2018 · 2018-12-31
The bank imported goods and stored them in a Free Trade Warehousing Zone before they were cleared. It asked whether integrated tax was payable again when the goods were removed from the zone to the domestic tariff area, over and above the tax collected at the time of customs clearance. The Authority, following Circular No. 3/1/2018-IGST dated 25 May 2018, held that the applicant is not liable to pay IGST at the time of removal, the levy arising once at clearance for home consumption.
What to do about it: Chennai importers using FTWZ facilities pay IGST once at clearance and should resist any demand for a second levy on removal.
GSTN Advisory dated 14 November 2023 — Form GST DRC-01C under Rule 88D of the CGST Rules · 2023-11-14
Where the input tax credit availed in GSTR-3B exceeds the credit available in GSTR-2B by more than the prescribed limit, the portal issues an intimation in Form GST DRC-01C. The taxpayer must reverse the excess with interest through DRC-03 or file a reply in Part B giving reasons, within seven days. If neither is done, the filing of the next GSTR-1 or Invoice Furnishing Facility statement is blocked.
Practical effect: Match your credit register against GSTR-2B before filing GSTR-3B, since an unexplained excess now stops your outward return.
35th GST Council Meeting, New Delhi — 21 June 2019 · 2019-06-21
At the first meeting chaired by Finance Minister Nirmala Sitharaman, the Council decided to introduce an electronic invoicing system in a phase-wise manner for business-to-business transactions. The press release recorded that e-invoicing would help taxpayers with backward integration and automation of tax-relevant processes and would help authorities combat evasion, with Phase 1 proposed to be voluntary and rolled out from January 2020. This decision is the origin of the Invoice Registration Portal, the IRN and the QR code now mandatory for most mid-sized and large businesses.
Why this matters: Every later e-invoicing threshold reduction, down to the Rs 5 crore limit now applicable, traces back to this decision, so businesses crossing a threshold must set up e-invoicing from the first day of the next financial year.
