Most of it happens without you leaving your shop counter. Share your documents on WhatsApp, approve the prepared draft, and your GSTR-1 & GSTR-3B Monthly Filing is completed on the portal from Rs.749 — by a Chennai team that businesses across Kotturpuram have relied on for years.
We serve businesses on and around Karunanidhi 1st Street — 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.
Finding dependable GSTR-1 & GSTR-3B Monthly Filing in Kotturpuram usually means choosing between a distant online portal and an overloaded local accountant. 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 offer a third option: a professional Chennai GST practice that treats Kotturpuram, Adyar and Nandanam as home ground, responds the same working day, files ahead of deadlines, and stands behind its work if a notice ever arrives on a return we prepared.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
A registration cancelled for non-filing is not the end of the road. We bring the pending returns up to date, clear the dues and file the revocation application in REG-21 within the permitted window, restoring suspended and cancelled GSTINs to active status.
E-invoicing is mandatory once turnover crosses Rs.5 crore and e-way bills apply to goods movements above Rs.50,000. We set up, train and troubleshoot both systems, so your despatches from Kotturpuram are never held up by a compliance gap at the gate.
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.
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.
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 Kotturpuram are comfortable with, and keeps written communication simple and jargon-free.
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 Kotturpuram always know exactly what the engagement costs them.
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.
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.
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.
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.
E-commerce platforms continuously validate seller GSTINs and filing status. A consistently compliant registration keeps your listings active and settlements flowing, with no sudden suspension of your online sales channel.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Karunanidhi 1st Street is a residential street in Kotturpuram, about 600 m south-east of the centre of Kotturpuram. The same consultant covers the streets immediately around it — 4th Street (about 50 m); Pondicherry Road (about 100 m); Tiruvalluvar Nagar 1st Street (about 100 m); Ellaiamman Koil Street (about 200 m) — so a site visit on Karunanidhi 1st Street can usually be combined with other work in Kotturpuram on the same trip. For GST purposes an address on Karunanidhi 1st Street falls under the Chennai South CGST Commissionerate, and the Kotturpuram pincode is 600085.

GSTN Advisory, September 2024 — implementation of the reduced Table 5 threshold notified by Notification No. 12/2024-Central Tax, dated 10 July 2024 · 2024-09
The threshold for invoice-wise reporting of inter-state supplies to unregistered persons in Table 5 of GSTR-1 and the corresponding table of GSTR-5 was reduced from Rs 2.5 lakh to Rs 1 lakh. GSTN implemented the change on the portal and advised taxpayers that each inter-state business-to-consumer invoice above Rs 1 lakh must now be reported separately with the place of supply, instead of being merged into the consolidated state-wise summary in Table 7.
What to do about it: Configure your billing software to flag inter-state retail bills above Rs 1 lakh, since a wrong place of supply here creates state-level revenue mismatch notices.
Notification No. 2/2025-Compensation Cess (Rate), dated 17 September 2025 · 2025-09-17
Alongside the new rate schedules, this notification amends the 2017 compensation cess rate notification to bring the cess down to nil on nearly every entry with effect from 22 September 2025, because the goods that had carried cess were absorbed into the new eighteen and forty per cent rates. Only pan masala, tobacco and related products continued to carry cess after that date, pending discharge of the compensation loan obligations.
What it means for you: Car and aerated drink dealers stopped charging compensation cess from 22 September 2025 and should have cleared the balance in their separate cess credit ledger.
Goodwill Industrial Canteen - AAR Tamil Nadu, Order No. TN/09/AAR/2018, dated 30 August 2018 · 2018-08-30
The applicant prepared food and served it in the canteens of client companies at their premises. It sought the rate applicable to this arrangement. The Authority held that the supply of food and beverages on the premises of an industrial undertaking was taxable at 18 percent up to 26 July 2018 and at 5 percent from 27 July 2018, when the restaurant service entry was amended to cover canteens at offices and factories, the concessional rate being available without input tax credit.
Practical effect: Chennai canteen contractors should bill factory and office canteens at 5 percent and forgo input tax credit on their purchases.
