Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd

We serve businesses on and around Sudarshan Nagar Main Road — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

Choosing GSTR-1 & GSTR-3B Monthly Filing in Madambakkam is ultimately an act of trust: you are handing over sales figures, purchase records and portal access. Madambakkam, built around the Chola-era Dhenupureeswarar Temple and Madambakkam Lake, has turned from farmland into a plotted-layout suburb threaded by Madambakkam High Road and the Santhosapuram - Vengaivasal - Mambakkam Road. Works contractors, borewell operators, building material suppliers and layout promoters dominate. Works contract classification, the twelve versus eighteen per cent dispute and Section 17(5) credit blocks are the recurring GST battles here. We earn that trust the unglamorous way — fixed fees honoured, drafts approved by you before filing, acknowledgements shared the same day, and strict confidentiality throughout. Clients across Madambakkam, Rajakilpakkam and Selaiyur have stayed with us for years on precisely this basis.
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.
You receive a WhatsApp message when documents are received, when the draft is ready for your approval, and when the return or application is filed, along with the acknowledgement. You never have to call and ask what is happening with your file.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
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.
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.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Madambakkam. 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.
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.
Statutory windows such as thirty days for an ASMT-11 reply are tracked from the day a notice arrives, so responses go in on time, complete, and with your best case properly presented.
Your scheme choice — regular, composition or QRMP — is re-examined as turnover and margins change, so you are always paying under the structure that legitimately costs your business the least.
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.
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.
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.
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 |
|---|---|---|
| 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. |
| 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. |
| Time cost | Roughly an hour a month to send data and approve drafts; the portal work, reconciliation and follow-up are ours. | Hours every month lost to portal errors, JSON files, OTP failures and reworking figures — usually on the due date itself. |
| 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. |
| 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. |
| 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. |
Sudarshan Nagar Main Road is a residential street in Madambakkam, about 800 m east of the centre of Madambakkam.

For GST purposes an address on Sudarshan Nagar Main Road falls under the Chennai Outer CGST Commissionerate, and the Madambakkam pincode is 600126.

3rd GST Council Meeting, New Delhi — 18-19 October 2016 (Signed Minutes, Agenda Item 2) · 2016-10-18
The Chairperson offered a compromise between a fixed 13 per cent growth rate, an average of three of the preceding five years' growth after removing the highest and lowest, and a 14 per cent rate pressed by Kerala and Assam. The Council unanimously agreed that projected State revenue for compensation purposes would grow at a flat 14 per cent per year from the 2015-16 base, with CST in that base counted at the actual 2 per cent. This single number determined the size of the compensation bill for the five-year guarantee period and, when actual GST collections fell short of it, drove the compensation cess extensions and the back-to-back borrowing arrangements of later years.
How we apply it: The 14 per cent guarantee is the reason compensation cess outlived its original five-year sunset, so cess-bearing goods remain costlier than the headline GST rate suggests.
Coronation Arts Crafts - AAR Tamil Nadu, Advance Ruling No. 19/ARA/2022, dated 31 May 2022 · 2022-05-31
A printing house printed leaflets and similar material using content supplied by the customer but paper, ink and other physical inputs of its own. It asked for the correct classification and rate. The Authority held that this is a composite supply in which the printing service is the principal supply, and the supply is therefore taxable at 18 percent. The customer supplying only the content or artwork did not alter the classification.
What to do about it: A Chennai printer supplying its own paper should charge 18 percent on job printed leaflets instead of assuming a lower book rate.
Megha Engineering and Infrastructures Ltd v. Commissioner of Central Tax — Telangana High Court, judgment dated 18 April 2019 · 2019-04-18
The taxpayer filed GSTR-3B late and paid interest only on the net cash portion of the tax. The High Court held that on the language of Section 50 as it then stood, interest ran on the gross liability, because input tax credit is credited to the ledger only when the return is filed. The decision caused wide concern in trade, and Parliament later amended Section 50 with retrospective effect from 1 July 2017 to charge interest only on the cash component in most late-return cases.
How we apply it: For late returns, interest is now generally computed on the cash portion only — if an older notice demands interest on gross tax, rely on the retrospective proviso to Section 50.
