Thoraipakkam sits where Rajiv Gandhi Salai meets the Pallavaram - Thoraipakkam Road, and its frontage carries IT offices, coworking spaces, car showrooms, cloud kitchens, furniture and hardware dealers, plus paying-guest hostels serving Secretariat Colony and Kumaran Kudil. Restaurant chains on the OMR service road and promoters in the interior streets struggle with e-invoicing thresholds, blocked credit on restaurant supply and monthly GSTR-3B reconciliation against GSTR-2B. That commercial character shapes the GST questions we see from Thoraipakkam every week — registrations, monthly returns, credit mismatches and departmental queries. We deliver GSTR-1 & GSTR-3B Monthly Filing for businesses in Thoraipakkam, and clients also reach us from Perungudi and Karapakkam nearby. Documents move over WhatsApp, drafts are approved before filing, and a senior consultant reviews every submission, so distance from our office never dilutes the quality of the work.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
We are a Chennai firm with a physical office, not a faceless portal. If you prefer to sit across a table with your papers, you are welcome. Clients from Thoraipakkam regularly visit us for registrations, notice discussions and annual return reviews.
Quarterly filing still demands monthly attention — IFF uploads so your buyers see their credit on time, and tax payment through PMT-06 by the 25th for the first two months of each quarter. We run that monthly rhythm so QRMP saves you effort without creating gaps.
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.
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.
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.
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.
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.
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.
Continuous filing protects you from the suspension and cancellation proceedings that hit chronic non-filers, so your registration, e-way bill access and ability to issue tax invoices are never suddenly cut off.
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.
Late-fee waivers and amnesty windows notified by the GST Council are applied to your history within their deadlines, capturing reliefs that most businesses only hear about once the window has already closed.
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 |
|---|---|---|
| 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. |
| Input tax credit | Purchase register matched against GSTR-2B each period, with defaulting suppliers chased so eligible credit is actually captured. | Credit claimed from books alone; mismatches with GSTR-2B mean lost credit or excess claims that invite departmental queries. |
| 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. |
| 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. |
| 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. |
| 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. |

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.
India Yamaha Motor (P) Ltd v. Assistant Commissioner — Madras High Court, W.P. No. 19044 of 2019, decided 29 August 2022 (Anita Sumanth J.) · 2022-08-29
The taxpayer argued that because credit was sitting in its electronic credit ledger, no interest should arise on delayed returns. The Madras High Court largely rejected this, confirming an interest demand of about Rs. 1.19 crore and holding that credit is set off against output tax only when it is actually debited at the time the return is filed. Availability of a credit balance, without an accompanying return, does not amount to discharge of tax.
What it means for you: Sitting on an unused credit balance is no defence to interest — the return must actually be filed and the credit debited for the liability to be treated as discharged.
Notification No. 15/2021-Central Tax (Rate) dated 18.11.2021 · 2021-11-18
This notification removed the words governmental authority and government entity from the concessional works contract entries in the services rate notification. With effect from 1 January 2022, works contract services supplied to a governmental authority or a government entity ceased to enjoy the 12 per cent rate and moved to 18 per cent with input tax credit. Only supplies made directly to the Central Government, a State Government, a Union territory or a local authority continued at the concessional rate at that stage.
What it means for you: Chennai contractors working for boards, corporations and government companies moved to 18 per cent from 1 January 2022, and should have raised price-variation claims for contracts signed earlier.
