Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Late fees, blocked credit and mismatch notices cost far more than professional help ever will. We complete GSTR-1 & GSTR-3B Monthly Filing for Kolathur businesses from Rs.749, matching every figure against portal data before anything reaches the department.
We serve businesses on and around Thiruveethiamman Koil Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

Kolathur is India's best-known ornamental fish hub, with breeding farms and aquarium shops clustered off Red Hills Road near Retteri junction, alongside hardware stores and construction material suppliers serving fast-growing residential pockets like Poombuhar Nagar. Many fish breeders and online sellers cross the Rs.40 lakh goods threshold without realising it, making first-time registration and e-commerce reporting the local GST pain point. When businesses of this kind evaluate GSTR-1 & GSTR-3B Monthly Filing, the real question is not price alone but who answers when something goes wrong. We serve Kolathur, Villivakkam and Perambur on a standing commitment: responses within the same working day, senior scrutiny before every submission, and continued support if the department ever writes back on work carrying our preparation.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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 Kolathur often discover in this first review exactly why their previous arrangement was costing them money.
GST is confusing enough without a language barrier. Our team explains notices, tax positions and filing requirements in plain Tamil or English, whichever you and your staff in Kolathur are comfortable with, and keeps written communication simple and jargon-free.
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 Kolathur never leave marketplace deductions unclaimed.
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 Kolathur through each of these so month one starts correctly.
We tell you when the composition scheme stops making sense, when QRMP suits your cash flow, and when a supplier's non-compliance is quietly costing you credit. Filing is the minimum; helping you make better GST decisions is the actual job.
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.
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.
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.
Sales returns, discounts and price revisions are adjusted through properly reported credit notes within the statutory window, so you never keep paying tax on turnover you have already reversed.
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.
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.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| Input tax credit | Purchase register matched against GSTR-2B each period, with defaulting suppliers chased so eligible credit is actually captured. | Credit claimed from books alone; mismatches with GSTR-2B mean lost credit or excess claims that invite departmental queries. |
Positions we rely on when preparing filings and drafting replies — with the exact citation, so you can verify each one.
Circular No. 236/30/2024-GST · 2024-10-11
CBIC explained the scope of the phrase 'regularised on as is where is basis' used when the Council settles a disputed rate or classification. Where taxpayers paid at the lower of two competing rates or claimed an exemption in good faith, the past position is accepted as full discharge and no differential demand arises. However, no refund is available to anyone who paid at the higher rate or did not claim the exemption, and the circular works through illustrations showing exactly which past positions stand closed.
Practical effect: Read any rate clarification circular alongside its regularisation paragraph, because that paragraph often extinguishes the entire exposure for earlier years.
Tamil Nadu Labour Welfare Board - AAR Tamil Nadu, advance ruling reported August 2021 · 2021
The Board, based at the DMS Campus in Teynampet, Chennai, owned immovable property and let portions of it to government departments and business entities. It asked whether it needed registration and whether the rent was exempt because the tenant was the government. The Authority held that renting of commercial property by the Board to a government or a business entity is not an exempt supply, so GST was payable on the rent collected.
What it means for you: Chennai landlords letting premises to government offices must charge GST unless a specific exemption entry clearly covers the letting.
9th GST Council Meeting, New Delhi — 16 January 2017 (Signed Minutes, Agenda Item 3) · 2017-01-16
The dual-control deadlock that had stalled several earlier meetings was broken. The Council agreed that taxpayers would be divided between Central and State tax administrations for all administrative purposes: of taxpayers with turnover below Rs 1.5 crore, 90 per cent would go to the State administration and 10 per cent to the Centre, while taxpayers above Rs 1.5 crore would be split equally. Division was to be by computerised stratified random sampling at the State level, with both administrations retaining intelligence-based enforcement powers over the whole value chain. West Bengal recorded its dissent.
Why this matters: This is why a Chennai taxpayer is assigned either to the Tamil Nadu Commercial Taxes Department or to CGST Chennai, and why notices come from only one of them for routine matters.
