GSTR-1 & GSTR-3B Monthly Filing in Karapakkam does not have to mean portal errors, guesswork and due-date tension. For a fixed fee starting Rs.749, an accountable Chennai practice prepares, reconciles, reviews and files — and remains answerable long after the acknowledgement arrives.
We serve businesses on and around Rajiv Gandhi Salai — 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. Karapakkam runs along Rajiv Gandhi Salai past the ELCOT SEZ, with IT and BPO units, facility-management and catering contractors, logistics operators, and hardware and fit-out firms clustered around Fourrts Avenue and the Riverview streets. SEZ-facing supplies demand endorsed invoices and correct zero-rating, while contractors face reverse charge on security and manpower services and frequent GSTR-2B mismatches on input credit. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Karapakkam follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Thoraipakkam and Sholinganallur 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.
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 Karapakkam, so inputs sent out for processing never quietly convert into a deemed supply carrying tax and interest.
E-invoicing is mandatory once turnover crosses Rs.5 crore and e-way bills apply to goods movements above Rs.50,000. We set up, train and troubleshoot both systems, so your despatches from Karapakkam are never held up by a compliance gap at the gate.
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.
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.
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 Karapakkam never leave marketplace deductions unclaimed.
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.
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.
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.
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.
With returns filed ahead of the statutory due dates every period, the Rs.50-per-day GSTR-3B late fee simply stops appearing in your life, and the money stays in your business where it belongs.
Correct, complete tax invoices signal a well-run business to customers, vendors and banks alike, quietly strengthening your credibility in every transaction where your paperwork is seen.
Funding rounds, partnerships and business sales all begin with a compliance check. A clean, documented GST history lets you clear that scrutiny quickly instead of watching a deal stall over old filing gaps.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| Registration and amendments | Query-resistant applications prepared correctly the first time, with supporting documents matched to what proper officers actually verify. | Repeated clarification memos and resubmissions, with weeks lost because a rent agreement or premises photograph did not meet expectations. |
| 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. |
| 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. |
| 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. |

GSTN Advisory, January 2024 — introduction of Tables 14 and 15 in GSTR-1 and the Invoice Furnishing Facility · 2024-01
From the January 2024 tax period, GSTR-1 and the Invoice Furnishing Facility carry two additional tables. Table 14 is filed by the seller and splits supplies made through an e-commerce operator between those on which the operator collects tax at source under Section 52 and those on which the operator itself pays tax under Section 9(5). Table 15 is filed by the e-commerce operator for supplies on which it discharges the tax under Section 9(5).
How we apply it: Sellers on marketplaces must map each order to the correct table, because mismatches here drive notices on tax collected at source credit.
Tamil Nadu Water Investment Company Ltd - AAR Tamil Nadu, advance ruling reported at 2019 (2) TMI 187 · 2019
The Chennai company provided management consultancy and detailed project report services to the Chennai Metro Water Supply and Sewerage Board for water related projects. It asked whether the service attracted GST. The Authority held that the supply was a pure service with no supply of goods involved, rendered in relation to a function entrusted to a municipality, and was therefore exempt from GST under the entry covering pure services supplied to government and local authorities.
How we apply it: Chennai consultants on government water and civic projects should test the pure services exemption before adding GST to their invoices.
Notification No. 2/2025-Compensation Cess (Rate), dated 17 September 2025 · 2025-09-17
Alongside the new rate schedules, this notification amends the 2017 compensation cess rate notification to bring the cess down to nil on nearly every entry with effect from 22 September 2025, because the goods that had carried cess were absorbed into the new eighteen and forty per cent rates. Only pan masala, tobacco and related products continued to carry cess after that date, pending discharge of the compensation loan obligations.
What it means for you: Car and aerated drink dealers stopped charging compensation cess from 22 September 2025 and should have cleared the balance in their separate cess credit ledger.
