Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Mandaveli 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 South Canal Bank Road — 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.
Mandaveli is a dense middle-class trading strip along R.K. Mutt Road, where provision stores, sweet stalls, silk and readymade shops, banks and the MTC bus terminus serve Mylapore's southern flank, with the Mandaveli Market feeding daily vegetable trade. Most shops are family-run B2C businesses hovering near the Rs.40 lakh goods threshold, so registration timing, composition scheme choice and GSTR-3B late fees dominate consultations. GST compliance in a market like Mandaveli rewards consistency — returns that match, credits that reconcile, and records that stand up to scrutiny. Our team provides GSTR-1 & GSTR-3B Monthly Filing to businesses throughout Mandaveli and nearby Mylapore and Raja Annamalaipuram on fixed, transparent fees. From the first document checklist to the final acknowledgement on WhatsApp, the process is structured so nothing depends on memory, luck or a due-date-evening scramble.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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 Mandaveli often discover in this first review exactly why their previous arrangement was costing them money.
No filing leaves our desk on a junior's judgement alone. A senior GST practitioner reviews your figures, ITC claims and tax computation before submission, so errors are caught at our table and not by the department months later through a notice.
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.
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 Mandaveli always know exactly what the engagement costs them.
GSTR-1 requires four-digit HSN reporting for turnover up to Rs.5 crore and six digits above it, and a wrong code often means a wrong rate. We verify the classification of what you actually supply, so your invoices and returns rest on defensible codes.
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.
Timeline: Filed before the 11th and 20th of every month · No hidden charges · GST invoice provided
Rs.7,999/year
Practical outcomes our clients measure us by.
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.
Amounts deducted by government buyers as GST TDS and by marketplaces as TCS are accepted on the portal each period, so money withheld against your GSTIN actually reaches your cash ledger instead of lying unclaimed.
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.
Filed returns, challans, reconciliations and working papers are archived in order from day one. If an audit or departmental verification comes, your file is ready the same week, not assembled in a panic.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| Supplier defaults | Suppliers who stop uploading invoices are identified within the period and pursued before their default becomes your blocked credit. | Missing supplier invoices surface only when credit is denied, by which time recovering the amount from the vendor is difficult. |
South Canal Bank Road is a main connecting road in Mandaveli, about 550 m south-east of the centre of Mandaveli. The same consultant covers the streets immediately around it — Bharathy Nagar (about 50 m); 5th Trust Cross Street (about 150 m); 4th Trust Cross Street (about 150 m); 3rd Trust Main Road (about 150 m) — so a site visit on South Canal Bank Road can usually be combined with other work in Mandaveli on the same trip. For GST purposes an address on South Canal Bank Road falls under the Chennai North CGST Commissionerate, and the Mandaveli pincode is 600028.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
TVH Lumbini Square Owners Association - AAR Tamil Nadu, Order No. 25/ARA/2019, dated 21 June 2019 · 2019-06-21
A residents welfare association collected monthly maintenance contributions from its members. The Authority held that where the contribution per member exceeds Rs. 7,500 a month, GST is payable on the entire contribution and not merely on the amount above Rs. 7,500. The Madras High Court subsequently held, in Greenwood Owners Association, that only the excess over Rs. 7,500 is taxable, and associations now follow that judicial position.
Why this matters: Chennai apartment associations should apply the High Court position carefully and keep member-wise workings ready for departmental scrutiny.
GSTN Advisory dated 7 June 2025 — non-editable auto-populated liability in GSTR-3B · 2025-06-07
After an October 2024 advisory and a January 2025 deferment, GSTN confirmed that from the July 2025 tax period the auto-populated outward tax liability in GSTR-3B, drawn from GSTR-1, IFF or GSTR-1A, is hard-locked and cannot be edited manually while filing. Any correction to sales figures must be made through GSTR-1A before GSTR-3B is filed. The change is intended to end mismatches between GSTR-1 and GSTR-3B.
How we apply it: Reconcile sales data before filing GSTR-1 each month, since GSTR-3B can no longer be adjusted at the last minute.
LC Infra Projects (P) Ltd v. Union of India — Karnataka High Court, judgment dated 22 July 2019 · 2019-07-22
The department demanded interest for delayed payment of tax and attached the taxpayer's bank account without first issuing any show cause notice. The High Court held that issuance of a show cause notice is a mandatory pre-condition before recovery of interest, because the taxpayer must have an opportunity to dispute the period and the computation. The recovery action and the bank attachment were quashed, with liberty to the department to proceed afresh after proper notice.
Why this matters: Interest cannot be lifted from your bank account without warning — insist on a show cause notice and a chance to verify the calculation.
