GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Nandanam's Anna Salai frontage between the YMCA grounds and Nandanam Arts College carries car showrooms, corporate offices, banks and training institutes, with CIT Nagar's shops and service firms behind. Showrooms tracking vehicle margins and offices paying steep lease rents both feel the pinch of 18 per cent GST on commercial rent, and service firms must pay tax on advances received even before an invoice is raised. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Nandanam follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Teynampet and T. Nagar 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.
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 Nandanam are comfortable with, and keeps written communication simple and jargon-free.
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.
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 Nandanam often discover in this first review exactly why their previous arrangement was costing them money.
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 Nandanam are never held up by a compliance gap at the gate.
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 Nandanam compete with each other; complete confidentiality is a condition of our work.
In the days before the 11th and the 20th, our team runs extended hours and a strict internal queue, so a client who sends data late in the window is still filed on time. Peak-season crush at our end never becomes a late fee at yours.
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.
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.
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.
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.
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.
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.
Each period you receive a simple computation showing output tax, credit utilised and net cash payable, so GST becomes a number you understand and question rather than a figure you accept blindly.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
River View Road is a residential street in Nandanam, about 800 m south-east of the centre of Nandanam. The same consultant covers the streets immediately around it — Kotturpuram Bridge (about 350 m); Archbishop Mathias Road (about 550 m); 14th Street (about 600 m); 12th Street (about 600 m) — so a site visit on River View Road can usually be combined with other work in Nandanam on the same trip. For GST purposes an address on River View Road falls under the Chennai South CGST Commissionerate, and the Nandanam pincode is 600035.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
Circular No. 157/13/2021-GST dated 20 July 2021 · 2021-07-20
CBIC explained the effect of the Supreme Court's order of 27 April 2021 extending limitation. The extension applies where an appeal has to be filed against a quasi-judicial order before the Joint or Additional Commissioner (Appeals), the Commissioner (Appeals), the Appellate Authority for Advance Ruling, the Tribunal or the courts, or where a revision or rectification of an order has to be sought. It does not apply to proceedings a taxpayer has to initiate or compliances he has to make, which remain governed only by the statute and by the notifications issued under section 168A of the CGST Act, nor to the quasi-judicial work of officers such as deciding refund claims, revocation applications and demand adjudications, which may continue.
What it means for you: A Chennai taxpayer who missed an appeal deadline during the pandemic waves can rely on this relief, but return filing dates were never covered by it.
GSTN Advisory — Invoice Management System, live from 14 October 2024 · 2024-10-14
GSTN launched the Invoice Management System (IMS) on the portal from 14 October 2024. Buyers can now view each invoice uploaded by suppliers in GSTR-1, IFF or GSTR-1A and mark it as accepted, rejected or pending. These actions determine what flows into GSTR-2B, with the first IMS-based GSTR-2B generated on 14 November 2024 for the October 2024 period. Records left without action are treated as deemed accepted.
Practical effect: Set up a monthly IMS review before your GSTR-2B is generated so wrong or fraudulent supplier invoices do not silently enter your ITC.
CBIC v. Aberdare Technologies (P) Ltd — Supreme Court, 2025 (SLP against Bombay HC order dated 29-07-2024 dismissed) · 2025-03-21
The Bombay High Court permitted Aberdare Technologies to correct bona fide clerical errors in its GST returns beyond the statutory deadline where there was no loss of revenue. Dismissing the department's SLP, the Supreme Court observed that human errors are normal, denying correction unjustifiably burdens taxpayers and benefits the department at their cost, and asked CBIC to re-examine the rigid timelines for rectifying returns since software limitations cannot defeat substantive rights.
What it means for you: If a genuine clerical mistake in GSTR-1 or GSTR-3B is blocking your customer's ITC or inflating your liability, courts now support rectification even beyond the deadline where revenue is not prejudiced.
