Finding dependable GSTR-1 & GSTR-3B Monthly Filing in Thoraipakkam usually means choosing between a distant online portal and an overloaded local accountant. 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. We offer a third option: a professional Chennai GST practice that treats Thoraipakkam, Perungudi and Karapakkam as home ground, responds the same working day, files ahead of deadlines, and stands behind its work if a notice ever arrives on a return we prepared.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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 Thoraipakkam compete with each other; complete confidentiality is a condition of our work.
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.
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.
Sellers on Amazon, Flipkart and other marketplaces face a three-way match between marketplace reports, GSTR-1 and the TCS the operator deposits against your GSTIN. We reconcile all three every period and accept the TCS credit, so sellers in Thoraipakkam never leave marketplace deductions unclaimed.
Goods sent to job workers must move on delivery challans, return within the statutory period, and be reported in ITC-04. We track every outward and return leg for manufacturing clients in Thoraipakkam, so inputs sent out for processing never quietly convert into a deemed supply carrying tax and interest.
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.
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.
With the LUT filed at the start of each financial year and refund claims tracked to credit, exporters supply without blocking funds in IGST and recover accumulated credit on schedule.
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.
Amounts deducted by government buyers as GST TDS and by marketplaces as TCS are accepted on the portal each period, so money withheld against your GSTIN actually reaches your cash ledger instead of lying unclaimed.
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.
Sales returns, discounts and price revisions are adjusted through properly reported credit notes within the statutory window, so you never keep paying tax on turnover you have already reversed.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Pallavan Kudiyiruppu 4th Cross Street is a residential street in Thoraipakkam, about 850 m south of the centre of Thoraipakkam.

GSTN Advisory dated 25 April 2025 — Phase-III of HSN reporting in Table 12 of GSTR-1/1A · 2025-04-25
GSTN implemented Phase-III of mandatory HSN reporting in Table 12 of GSTR-1 and GSTR-1A from the May 2025 return period, after the change was deferred from earlier periods. Manual keying of HSN codes is replaced by selection from a dropdown, Table 12 is split into separate B2B and B2C tabs, and new value validations compare the taxable values reported across tables. Table 13, the summary of documents issued, also became mandatory. Taxpayers up to Rs 5 crore turnover report 4-digit codes; larger taxpayers report 6-digit codes.
Why this matters: Update your billing software's HSN masters so every item carries a valid 4 or 6 digit code that matches the portal dropdown.
Notification No. 09/2018-Central Tax dated 23.01.2018 · 2018-01-23
This notification designated www.ewaybillgst.gov.in, managed by the National Informatics Centre, as the Common Goods and Services Tax Electronic Portal for the specific purpose of furnishing the electronic way bill. It thereby separated the e-way bill system from the main return and registration portal at www.gst.gov.in, which is why taxpayers maintain distinct credentials and a distinct login for e-way bill generation.
Why this matters: Chennai consignors and transporters must enrol separately on the e-way bill portal, and a GST portal login alone does not permit e-way bill generation.
9th GST Council Meeting, New Delhi — 16 January 2017 (Signed Minutes, Agenda Item 3) · 2017-01-16
The dual-control deadlock that had stalled several earlier meetings was broken. The Council agreed that taxpayers would be divided between Central and State tax administrations for all administrative purposes: of taxpayers with turnover below Rs 1.5 crore, 90 per cent would go to the State administration and 10 per cent to the Centre, while taxpayers above Rs 1.5 crore would be split equally. Division was to be by computerised stratified random sampling at the State level, with both administrations retaining intelligence-based enforcement powers over the whole value chain. West Bengal recorded its dissent.
Why this matters: This is why a Chennai taxpayer is assigned either to the Tamil Nadu Commercial Taxes Department or to CGST Chennai, and why notices come from only one of them for routine matters.
