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 Ambattur 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 Varadharajapuram — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Ambattur hosts one of South India's largest small-scale industrial estates, where thousands of engineering, auto component, garment and fabrication units operate across the North and South phases off MTH Road and Ambattur-Red Hills Road. Job work movements between units demand disciplined ITC-04 and delivery challan records, while exporters and units crossing Rs.5 crore turnover must manage LUT filings and e-invoicing. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Ambattur follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Avadi and Padi run on the same process, entirely over WhatsApp if they prefer.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
If a query, ASMT-10 scrutiny notice or DRC-01 arrives on a return we filed, we stand behind our work and help you draft the reply. You are not left alone with a departmental letter and a thirty-day clock ticking against you.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Ambattur. 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.
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.
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.
Composition dealers have their own rulebook — CMP-08 every quarter, GSTR-4 annually by 30 June, bills of supply instead of tax invoices, and a turnover ceiling that must be watched. We handle each of these correctly so the scheme's simplicity never turns into a violation.
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 Ambattur often discover in this first review exactly why their previous arrangement was costing them money.
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.
Correct, complete tax invoices signal a well-run business to customers, vendors and banks alike, quietly strengthening your credibility in every transaction where your paperwork is seen.
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.
Systematic GSTR-2B matching and supplier follow-up mean input tax credit that was leaking away under self-filing is captured each month, directly reducing the cash you pay out with every GSTR-3B.
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.
With the LUT filed at the start of each financial year and refund claims tracked to credit, exporters supply without blocking funds in IGST and recover accumulated credit on schedule.
| 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. |
| Annual return preparation | Monthly reconciliations roll naturally into GSTR-9, filed comfortably before 31 December with figures already agreed through the year. | Twelve months of unmatched data reconstructed in December, with differences discovered too late to be corrected cleanly. |
| 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. |
| 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. |
| 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. |
| 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. |

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.
How we apply it: Chennai canteen contractors should bill factory and office canteens at 5 percent and forgo input tax credit on their purchases.
GSTN Advisory, 2022 — Phase-II of mandatory HSN reporting in Table 12 of GSTR-1 from 1 November 2022 · 2022-11-01
Mandatory HSN reporting in Table 12 of GSTR-1 was introduced in phases from 1 April 2022, when the portal began flagging missing or short codes in warning mode. In Phase-II, from the November 2022 return period, taxpayers with annual aggregate turnover up to Rs 5 crore had to report at least four-digit HSN codes for all business-to-business supplies in Table 12, and taxpayers above Rs 5 crore had to report six digits for all supplies. Phase-III in 2025 went further and replaced manual entry with selection from a dropdown of valid codes.
What it means for you: Correct HSN codes once at the item-master level, so that each successive tightening of portal validation does not force fresh rework.
Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, Schedule I, S. Nos. 388 to 392 (Chapters 61 to 64) · 2025-09-17
From 22 September 2025 articles of apparel and clothing accessories of Chapters 61 and 62, other made-up textile articles of Chapter 63 and footwear of Chapter 64 attract five per cent where the sale value does not exceed Rs 2,500 per piece or per pair, and eighteen per cent where it exceeds that figure. The old thresholds of Rs 1,000 for garments and the flat twelve per cent on all footwear are gone, and the test is sale value, not maximum retail price.
Practical effect: A T. Nagar garment or footwear retailer must map every stock keeping unit against Rs 2,500 of actual sale value, because that single figure determines whether five or eighteen per cent applies.
