Ekkattuthangal, beside the Kathipara interchange, blends the SIDCO Industrial Estate's south phase with IT towers such as Olympia Technology Park and a strip of printing, packaging and engineering units off the Inner Ring Road. Units sending components out for plating or machining must move them on delivery challans and report the flows in ITC-04, a step many discover only when a departmental audit asks for job-work records. Against that backdrop, GSTR-1 & GSTR-3B Monthly Filing in Ekkattuthangal demands more than data entry — it needs reconciliation before filing, correct classification and awareness of what local officers examine. Our Chennai team provides exactly that to clients in Ekkattuthangal, Guindy and Jafferkhanpet, with same-day responses on working days and WhatsApp updates at every stage. Most routine engagements complete within one to two working days once documents are in hand.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
Businesses with registrations in more than one State, or multiple branches under one PAN, face cross-charge, stock transfer and input service distribution questions that single-GSTIN firms never see. We keep all your registrations consistent with each other, not just compliant individually.
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.
Traders, manufacturers, contractors, e-commerce sellers, professionals and service exporters — we have handled GST for all of them. Whatever mix of goods and services your Ekkattuthangal business supplies, the rate, classification and place-of-supply questions have almost certainly crossed our desk before.
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 Ekkattuthangal never leave marketplace deductions unclaimed.
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.
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.
Rates, reverse charge, place of supply and blocked credits are applied correctly at the preparation stage, so you neither overpay tax you do not owe nor underpay and invite demands with penalty later.
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.
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.
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.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Defence Colony 2nd Avenue is a residential street in Ekkattuthangal, about 600 m west of the centre of Ekkattuthangal.

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.
Circular No. 89/08/2019-GST dated 18 February 2019 · 2019-02-18
CBIC noticed that many taxpayers were not reporting details of inter-State supplies made to unregistered persons, composition dealers and UIN holders in Table 3.2 of FORM GSTR-3B, and in Table 7B of FORM GSTR-1 for invoices up to Rs 2.5 lakh. Because these figures drive the settlement of integrated tax between the Centre and the States, the circular directed that the information be furnished correctly and warned that failure attracts general penalty under section 125.
What it means for you: Businesses selling across State borders to consumers should keep Table 3.2 populated, since mismatches here are a common trigger for scrutiny notices.
State of West Bengal v. Calcutta Club Ltd — Supreme Court, (2019) 19 SCC 107, judgment dated 03-10-2019 · 2019-10-03
The Supreme Court held that the doctrine of mutuality survived the Forty-sixth Constitutional Amendment. Supplies of food, drink and services by an incorporated members' club to its own members are not a sale or a service to another person, so sales tax and service tax could not be levied. Note that GST law was later amended, with retrospective effect from 1 July 2017, to specifically tax supplies between a club or association and its members.
Practical effect: Chennai clubs, associations and resident welfare bodies cannot rely on mutuality under GST any longer, as the law was amended to override this ruling.
