One WhatsApp message is how most of our client relationships began. Send yours today and have GSTR-1 & GSTR-3B Monthly Filing in Kotturpuram handled end to end from Rs.749 — fee confirmed in writing first, documents straight from your phone, acknowledgement the day we file.
We serve businesses on and around Boat Club 3rd Avenue — 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.
If you operate in Kotturpuram, GST deadlines arrive with the same force as anywhere in Chennai — GSTR-1 by the 11th, GSTR-3B by the 20th. Kotturpuram, on the south bank of the Adyar around the Anna Centenary Library and the Housing Board blocks, is a professionals' quarter: independent consultants, architects, tutors and clinics work along Gandhi Mandapam Road and the numbered Main Roads. Many consultants billing from home offices cross the Rs.20 lakh services threshold quietly, and those serving overseas clients need a live LUT before invoicing exports without IGST. We provide GSTR-1 & GSTR-3B Monthly Filing to businesses across Kotturpuram and the adjoining Adyar and Nandanam localities, maintaining a compliance calendar for every client so due dates are met without last-minute panic, late fees or interest at 18 percent per annum.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Your sales figures, supplier lists and login credentials are handled only by our engaged team, stored securely and never shared with any third party. Many of our clients in Kotturpuram compete with each other; complete confidentiality is a condition of our work.
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.
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.
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 Kotturpuram never leave marketplace deductions unclaimed.
Tally, Zoho Books, Busy, marketplace reports, plain Excel or even a handwritten bill book — we take your data in whatever form your Kotturpuram business already maintains it. You are never forced to buy new software or retrain staff just to become our client.
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.
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.
Your billing staff are guided on invoice fields, rates and series discipline, so mistakes are prevented where they originate — at the counter — instead of being repaired later in the returns.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
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.
We spot suppliers who stop uploading invoices or filing returns and alert you before their default becomes your blocked credit, letting you recover amounts or switch vendors while the exposure is still small.
Illness, travel or a family function no longer threatens a deadline. With a standing external process holding your calendar and data trail, filings proceed on schedule whether or not you are at your desk.
When a business winds up, proper cancellation and a timely final return ensure the file is genuinely closed, so no demand or late-fee computation resurfaces against you long after the shutters came down.
| 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. |
| Risk of notices | GSTR-1, GSTR-3B and GSTR-2B reconciled before filing, removing the mismatches that trigger most scrutiny notices. | Inconsistent figures across returns quietly build a mismatch history that surfaces later as ASMT-10 scrutiny or a demand notice. |
| 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. |
| 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. |
| 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. |

The same consultant covers the streets immediately around it — Boat Club 2nd Avenue (about 150 m); River View Road (about 400 m); 4th Main Road Ext (about 400 m); Crescent Street (about 400 m) — so a site visit on Boat Club 3rd Avenue can usually be combined with other work in Kotturpuram on the same trip. For GST purposes an address on Boat Club 3rd Avenue falls under the Chennai South CGST Commissionerate, and the Kotturpuram pincode is 600085.

GST law moves through notifications, circulars and court decisions. These are the ones changing how filings are prepared right now.
Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, Schedule I entries for electrically operated vehicles and chargers · 2025-09-17
Electrically operated vehicles including two-wheelers and three-wheelers, fuel cell and hydrogen vehicles, e-bicycles and chargers or charging stations for electric vehicles remain in Schedule I at five per cent. Small petrol cars up to 1200 cc and up to 4000 mm, small diesel cars up to 1500 cc and up to 4000 mm and motorcycles up to 350 cc moved to eighteen per cent, while larger cars, hybrids above those limits and motorcycles above 350 cc were placed at forty per cent.
What to do about it: The tax gap between an electric two-wheeler at five per cent and a petrol motorcycle at eighteen per cent is now the single biggest pricing lever for Chennai vehicle dealers.
GSTN Advisory dated 7 June 2025 — barring of GST returns after three years (Finance Act, 2023; Notification No. 28/2023-Central Tax) · 2025-06-07
Implementing the Finance Act, 2023 amendments to Sections 37, 39, 44 and 52, notified by Notification No. 28/2023-Central Tax, GSTN advised that from the July 2025 tax period the portal blocks filing of GST returns once three years have passed from their due date. The bar covers GSTR-1, GSTR-1A, GSTR-3B, GSTR-4, GSTR-5, GSTR-5A, GSTR-6, GSTR-7, GSTR-8 and GSTR-9. Taxpayers with old pending returns were urged to reconcile their records and file before the returns became permanently time-barred on the portal.
How we apply it: Clear every pending old return now, because once the three-year window closes the portal will not accept the return and registration consequences follow.
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.
What it means for you: 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.
