GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Mudichur's construction boom along the Tambaram - Mudichur - Sriperumbudur Road and the Outer Ring Road has filled former paddy fields with apartment projects, plot promotions, building material yards, hardware and paint shops, water-can suppliers and packers-and-movers out to Varadharajapuram and Mannivakkam. Construction is the GST epicentre here: rate confusion on works contracts, the eighty per cent registered-purchase rule for promoters, and flood-season filing relief. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Mudichur follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Perungalathur and Varadharajapuram 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.
GSTR-3B late fees run at Rs.50 per day and interest at 18 percent per annum on unpaid tax. Our internal cut-offs sit days ahead of statutory due dates precisely so that our clients never hand the department a rupee they did not owe.
Most GST notices trace back to mismatches between GSTR-1, GSTR-3B and GSTR-2B. We reconcile these before filing, not after a notice arrives, so your returns are internally consistent and the most common triggers for ASMT-10 scrutiny simply never appear.
The annual return and, where turnover crosses Rs.5 crore, the self-certified reconciliation statement in GSTR-9C are prepared by the same team that filed your monthly returns. Nothing about your year has to be rediscovered or explained to a stranger in December.
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 Mudichur are never held up by a compliance gap at the gate.
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.
Winding up attracts its own GST obligations — the cancellation application, reversal of credit on closing stock, and the final return in GSTR-10 within three months. We close registrations properly so a business you shut in Mudichur never writes back to you as a demand years later.
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.
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.
Complete RFD-01 applications with proper statements and annexures move through the system faster and attract fewer deficiency memos, which means export and inverted-duty refunds reach your bank account sooner.
Funding rounds, partnerships and business sales all begin with a compliance check. A clean, documented GST history lets you clear that scrutiny quickly instead of watching a deal stall over old filing gaps.
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.
When GST knowledge lives inside a single staff member, their resignation becomes a compliance crisis. With our firm as the standing process, your filings continue uninterrupted regardless of internal staff changes.
Because monthly data is reconciled as it happens, GSTR-9 preparation before the 31 December due date becomes a review exercise rather than a painful reconstruction of twelve untidy months.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Thiru. Vi. Ka. Street is a residential street in Mudichur, about 300 m north-west of the centre of Mudichur. The same consultant covers the streets immediately around it — Ellai Amman Koil Street (about 50 m); Rajarajan Street (about 400 m); Doctor Kalaignar M. Karunanithi Road (about 450 m); Tambaram - Manimangalamr - Sriperumbudur Road (about 450 m) — so a site visit on Thiru. Vi. Ka. Street can usually be combined with other work in Mudichur on the same trip. For GST purposes an address on Thiru. Vi. Ka. Street falls under the Chennai Outer CGST Commissionerate, and the Mudichur pincode is 600048.

A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
Krishna Bhavan Foods and Sweets - AAR Tamil Nadu, Order No. TN/24/AAR/2021, dated 18 June 2021, upheld by AAAR Tamil Nadu, Order No. TN/AAAR/02/2022, dated 13 January 2022 · 2021-06-18
The applicant sold packaged ready to cook instant mixes for dosai, idli, tiffin items, sweets, health mix and porridge. It argued that these were only flours of cereals and pulses taxable at 5 percent. The Authority classified the products under heading 2106 90 as food preparations not elsewhere specified, attracting 18 percent GST, because the mixing and added ingredients took them out of the concessional flour entries. The Appellate Authority upheld that classification.
How we apply it: Chennai food manufacturers selling instant mixes should confirm whether the product is a plain flour or a preparation before applying 5 percent.
Circular No. 76/50/2018-GST dated 31 December 2018 · 2018-12-31
This circular answered a set of unrelated questions. The most important is that the penalty under section 73(11) does not apply where self-assessed tax shown in the return is paid late; only interest under section 50 and, where warranted, general penalty under section 125 arise. It also dealt with the rate applicable to notes issued under section 142(2) and who is the owner of goods in transit. A corrigendum of 7 March 2019 clarified that tax collected at source under the Income-tax Act is not included in the taxable value.
Practical effect: If a demand adds a heavy penalty simply because GSTR-3B tax was paid late, this circular is the answer.
Mr. Kannippan Arumugan v. Assistant Commissioner (ST) — Madras High Court, W.P. No. 2943 of 2026, decided 30 January 2026 (C. Saravanan J.) · 2026-01-30
The taxpayer had reported tax of Rs 2,54,040.30 against an invoice instead of the correct Rs 1,31,280.30, and a demand followed. The Court quashed the assessment order dated 21 July 2025 and remitted the matter for fresh adjudication within six months, permitting the petitioner to rectify the inadvertent error subject to compliance with Circular No. 212/6/2024-GST, and directing the officer to verify with the recipient's jurisdiction whether excess credit had in fact been availed.
What it means for you: A clerical overstatement in GSTR-1 by a Chennai supplier can still be corrected long afterwards, provided the recipient has not taken the excess credit and the Circular 212 procedure is followed.
