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

Kathivakkam is a fishing town wedged between the Ennore Creek and the Chennai-Ennore Expressway, where Thazhankuppam and Ernavur kuppams supply fish traders and ice plants, and works contractors serve the Ennore Thermal Power Station, Ennore Foundries and the container traffic moving down Manali High Road. Labour and works contractors here face reverse charge and GST-TDS issues, and fish traders need clarity on exempt versus processed supplies. GST compliance in a market like Kathivakkam rewards consistency — returns that match, credits that reconcile, and records that stand up to scrutiny. Our team provides GSTR-1 & GSTR-3B Monthly Filing to businesses throughout Kathivakkam and nearby Ennore and Ernavur on fixed, transparent fees. From the first document checklist to the final acknowledgement on WhatsApp, the process is structured so nothing depends on memory, luck or a due-date-evening scramble.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Every acknowledgement, challan, computation sheet and filed return is saved and shared with you in an organised folder. When a bank, buyer or GST officer asks for a document from two years ago, it reaches you the same day without any scrambling.
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.
We tell you when the composition scheme stops making sense, when QRMP suits your cash flow, and when a supplier's non-compliance is quietly costing you credit. Filing is the minimum; helping you make better GST decisions is the actual job.
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.
Composition dealers have their own rulebook — CMP-08 every quarter, GSTR-4 annually by 30 June, bills of supply instead of tax invoices, and a turnover ceiling that must be watched. We handle each of these correctly so the scheme's simplicity never turns into a violation.
OTP failures, DSC errors, stuck submissions on due-date evenings — we deal with the GST portal daily and know the workarounds. When the site misbehaves on the 20th, our team keeps retrying and escalating so your return still goes through.
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.
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.
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.
A fixed professional fee is almost always cheaper than the combination of late fees, interest, lost credit and staff hours that informal, last-minute compliance quietly accumulates over a year.
Loan applications and government tenders routinely demand GST returns and registration documents. With everything filed and archived properly, you can produce a complete compliance file within hours instead of days.
Because turnover in your GST returns is kept aligned with your accounts through the year, income tax filing and statutory audit proceed without the GST-versus-books mismatch queries that now surface routinely through data matching.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Railway Station Road is a residential street in Kathivakkam, about 500 m north-east of the centre of Kathivakkam. The same consultant covers the streets immediately around it — Chennai - Ennore Road (about 450 m); Chennai - Ennore Road Tunnel (about 550 m); 10th Street (about 700 m); 2nd Main Road (about 700 m) — so a site visit on Railway Station Road can usually be combined with other work in Kathivakkam on the same trip. For GST purposes an address on Railway Station Road falls under the Chennai North CGST Commissionerate, and the Kathivakkam pincode is 600057.

WABCO India Ltd - AAR Tamil Nadu, Order No. TN/10/AAR/2018, dated 27 September 2018 · 2018-09-27
The manufacturer supplied electrical wiring harness, essentially electrical wire with connectors at both ends, used in motor vehicles, and asked whether it should be classified as a motor vehicle part or as insulated electrical conductors. The Authority classified the product under heading 8544, which covers insulated wire and cable fitted with connectors, taxable at 9 percent central tax and 9 percent State tax following Notification No. 41/2017-Central Tax (Rate) dated 14 November 2017, the earlier rate having been higher.
How we apply it: Chennai auto component makers should classify by the tariff description of the article itself, not by the vehicle it eventually goes into.
Notification No. 03/2017-Central Tax dated 19.06.2017 · 2017-06-19
This notification made the Central Goods and Services Tax Rules, 2017. In its original form it carried the chapters on preliminary definitions, composition levy and registration, together with the associated forms in the REG and CMP series. Every later amendment to the GST rules, from e-way bills to input tax credit restrictions to annual return formats, is technically an amendment to the rules notified here.
Practical effect: When a Chennai officer cites a rule number, this is the parent notification, and the rule must be read as it stood on the date of your transaction, not as it reads today.
Circular No. 203/15/2023-GST · 2023-10-27
CBIC clarified three recurring place-of-supply questions. For transportation of goods, including by mail or courier, where the supplier or the recipient is outside India, Section 13(9) of the IGST Act stood omitted from 1 October 2023, so the place of supply is now fixed by the default rule in Section 13(2), namely the location of the recipient. For advertising services supplied to a government body, the place of supply follows the location of the recipient under Section 12(2) rather than the location of the hoardings, with State-wise allocation where the contract provides for it. For co-location of servers in a data centre, the supply is a bundle of hosting services and not a letting of immovable property, so the recipient's location governs.
Why this matters: Chennai courier, advertising and data centre businesses should map their invoices to these tests before deciding between IGST and CGST plus SGST.
