The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Korukkupet permanently ahead of both, delivering GSTR-1 & GSTR-3B Monthly Filing from Rs.749 with reconciliation, senior review and WhatsApp acknowledgements as standard.
We serve businesses on and around Cochrane Basin Road — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Korukkupet is defined by the oil marketing company terminals off Thiruvottiyur High Road and Ennore High Road, the Korukkupet goods shed and the Cochrane Basin Road level crossing. Tanker fleet owners, terminal contractors, clearing agents and the Kalmandapam Road trading rows work around petroleum products staying outside GST, blocked input credit on such supplies, and reverse charge on inward goods transport. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Korukkupet follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Old Washermanpet and Tondiarpet 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.
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 Korukkupet compete with each other; complete confidentiality is a condition of our work.
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.
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.
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 Korukkupet, so inputs sent out for processing never quietly convert into a deemed supply carrying tax and interest.
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 Korukkupet often discover in this first review exactly why their previous arrangement was costing them money.
A registration cancelled for non-filing is not the end of the road. We bring the pending returns up to date, clear the dues and file the revocation application in REG-21 within the permitted window, restoring suspended and cancelled GSTINs to active status.
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.
Systematic GSTR-2B matching and supplier follow-up mean input tax credit that was leaking away under self-filing is captured each month, directly reducing the cash you pay out with every GSTR-3B.
When GST knowledge lives inside a single staff member, their resignation becomes a compliance crisis. With our firm as the standing process, your filings continue uninterrupted regardless of internal staff changes.
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.
E-commerce platforms continuously validate seller GSTINs and filing status. A consistently compliant registration keeps your listings active and settlements flowing, with no sudden suspension of your online sales channel.
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.
Whether moving between composition and regular scheme, opting into QRMP, or crossing the e-invoice threshold at Rs.5 crore, transitions are planned in advance rather than discovered after a compliance breach.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Cochrane Basin Road is a secondary arterial road in Korukkupet, about 1.7 km south of the centre of Korukkupet. The same consultant covers the streets immediately around it — Boja Raja Nagar (about 700 m); Vijayaraghavelu Road (about 800 m); Boja Raja Nagar Main Road (about 800 m); Parthasarathy Bridge (about 800 m) — so a site visit on Cochrane Basin Road can usually be combined with other work in Korukkupet on the same trip. For GST purposes an address on Cochrane Basin Road falls under the Chennai North CGST Commissionerate, and the Korukkupet pincode is 600021.

M/s. New PSP Traders v. Deputy State Tax Officer — Madras High Court (Madurai Bench), W.P.(MD) No. 17026 of 2025, decided 25 June 2025 (C. Saravanan J.) · 2025-06-25
The assessment orders had denied input tax credit purely because the returns were filed after the Section 16(4) cut-off. The Court held that the challenge was squarely covered by newly inserted Section 16(5), which permits credit on invoices relating to the financial years 2017-18 to 2020-21 if taken in any return filed up to 30 November 2021, notwithstanding Section 16(4). The impugned orders were quashed and the matter remitted for fresh orders consistent with the amendment.
What it means for you: A Chennai dealer whose ITC for 2017-18 to 2020-21 was disallowed only for late filing should apply for rectification or move the High Court, since Section 16(5) now protects that credit.
GSTN Advisories, 2024 — enabling of credit card, debit card and UPI payment options on the GST portal · 2024
In addition to net banking, NEFT, RTGS and over-the-counter payment, GSTN enabled payment of GST through Unified Payments Interface and through credit and debit cards, routed via a payment gateway on the portal. The facility was rolled out State by State and now covers most States and Union Territories. Gateway or bank charges are borne by the taxpayer, and the amount reflects in the electronic cash ledger once the challan is confirmed.
What it means for you: Use UPI or card payment when a bank transfer will not clear in time, but confirm the credit in the cash ledger before filing the return.
Notification No. 10/2017-Central Tax dated 28.06.2017 · 2017-06-28
This notification amended the CGST Rules, 2017 as originally notified under Notification 03/2017-Central Tax, adding the substantive operating chapters that had been left out of the first tranche. These cover matters such as determination of value of supply, input tax credit, tax invoice, credit and debit notes, accounts and records, returns, payment of tax, refunds and assessment, together with their prescribed forms.
Practical effect: The rules governing invoicing, credit and refunds for a Chennai business date from 28 June 2017, so any compliance question about the first weeks of GST must be tested against this text.
