Every locality in Chennai has its own commercial rhythm, and Nandanam is no exception. 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. Our practice has shaped its GSTR-1 & GSTR-3B Monthly Filing work around exactly these realities, serving clients in Nandanam as well as Teynampet and T. Nagar. Registrations, returns, refunds and notice replies are handled by one accountable team, with fees fixed in writing before work begins and every filing reconciled against portal data before it is submitted.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
When an ADT-01 audit intimation or a personal hearing date arrives, we compile the records, prepare the reconciliations and draft the submissions, and coordinate closely with your authorised representative. You walk into the proceeding prepared, not improvising in front of an officer.
We match your purchase register against GSTR-2B every period, follow up on invoices your suppliers have not uploaded, and ensure every rupee of eligible input tax credit is claimed. Clients routinely recover credit they were silently losing under self-filing.
Whenever the GST Council notifies a late-fee waiver or an amnesty window for pending returns or old demands, we check every client's history against it and act within the deadline. Relief that businesses in Nandanam would otherwise read about after it lapsed reaches our clients in time.
OTP failures, DSC errors, stuck submissions on due-date evenings — we deal with the GST portal daily and know the workarounds. When the site misbehaves on the 20th, our team keeps retrying and escalating so your return still goes through.
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.
No filing leaves our desk on a junior's judgement alone. A senior GST practitioner reviews your figures, ITC claims and tax computation before submission, so errors are caught at our table and not by the department months later through a notice.
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.
Interest on delayed GST payment runs at 18 percent per annum, which is costlier than most working capital finance. Timely computation and payment through our calendar keeps that meter permanently at zero.
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.
Advances received for services attract GST on receipt while advances for goods generally do not; applying this distinction correctly means you neither prepay tax unnecessarily nor omit a liability that surfaces later with interest.
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.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
14th Street is a residential street in Nandanam, about 500 m east of the centre of Nandanam. The same consultant covers the streets immediately around it — 13th Street (about 50 m); 12th Street (about 50 m); 10th Street (about 100 m); 11th Street (about 100 m) — so a site visit on 14th Street can usually be combined with other work in Nandanam on the same trip. For GST purposes an address on 14th Street 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.
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.
How we apply it: 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.
Circular No. 137/07/2020-GST dated 13 April 2020 · 2020-04-13
CBIC answered questions arising from cancelled bookings and returned goods. Where an advance was received, tax paid and an invoice issued, and the contract was later cancelled, the supplier issues a credit note under section 34 and adjusts the liability; where only a receipt voucher was issued, he issues a refund voucher and claims refund of the excess tax paid in FORM GST RFD-01. It also confirmed that a Letter of Undertaking for 2020-21 could be filed up to 30 June 2020 while quoting the previous year's LUT number.
What it means for you: Tax paid on an advance for an order that never happened is recoverable, but only through the correct credit note or refund voucher route.
GSTN Advisory — negative values in Table 3.1 of GSTR-3B, January 2025 · 2025-01
GSTN enabled reporting of negative values in Table 3.1 of GSTR-3B from the January 2025 period onwards. Where credit notes issued in a month exceed outward supplies, the net negative figure now auto-populates instead of being forced to zero. The resulting negative liability is carried in the taxpayer's records and automatically adjusted against the liability of subsequent tax periods, removing a long-standing distortion for businesses with heavy sales returns.
What it means for you: Businesses with seasonal returns or large credit notes no longer need workarounds; let the negative figure flow and track its set-off next month.
