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. Against that backdrop, GSTR-1 & GSTR-3B Monthly Filing in Karapakkam 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 Karapakkam, Thoraipakkam and Sholinganallur, 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.
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.
GSTR-3B late fees run at Rs.50 per day and interest at 18 percent per annum on unpaid tax. Our internal cut-offs sit days ahead of statutory due dates precisely so that our clients never hand the department a rupee they did not owe.
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.
Quarterly filing still demands monthly attention — IFF uploads so your buyers see their credit on time, and tax payment through PMT-06 by the 25th for the first two months of each quarter. We run that monthly rhythm so QRMP saves you effort without creating gaps.
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 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.
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.
Where a genuine error is found in a past period, voluntary payment through DRC-03 before any notice issues closes the matter at minimal cost, instead of letting it ripen into a demand with penalty.
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.
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.
Large buyers check vendor GST compliance before releasing payments and renewing contracts. A clean filing record with timely GSTR-1 uploads keeps your invoices reflecting in their GSTR-2B and your payments unblocked.
Correct e-way bills matched to correct invoices mean your consignments clear roadside inspections cleanly, avoiding detention proceedings whose penalties can far exceed the tax on the goods being carried.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Easwaran Street is a main connecting road in Karapakkam, about 700 m south of the centre of Karapakkam. The same consultant covers the streets immediately around it — River View Residency 2nd Street (about 150 m); River View 1st Cross Street (about 200 m); 5th Riverview Street (about 250 m); Indira Gandhi Street (about 250 m) — so a site visit on Easwaran Street can usually be combined with other work in Karapakkam on the same trip. For GST purposes an address on Easwaran Street falls under the Chennai South CGST Commissionerate, and the Karapakkam pincode is 600097.

GSTN Advisory dated 7 June 2025 — non-editable auto-populated liability in GSTR-3B · 2025-06-07
After an October 2024 advisory and a January 2025 deferment, GSTN confirmed that from the July 2025 tax period the auto-populated outward tax liability in GSTR-3B, drawn from GSTR-1, IFF or GSTR-1A, is hard-locked and cannot be edited manually while filing. Any correction to sales figures must be made through GSTR-1A before GSTR-3B is filed. The change is intended to end mismatches between GSTR-1 and GSTR-3B.
What to do about it: Reconcile sales data before filing GSTR-1 each month, since GSTR-3B can no longer be adjusted at the last minute.
TVH Lumbini Square Owners Association - AAR Tamil Nadu, Order No. 25/ARA/2019, dated 21 June 2019 · 2019-06-21
A residents welfare association collected monthly maintenance contributions from its members. The Authority held that where the contribution per member exceeds Rs. 7,500 a month, GST is payable on the entire contribution and not merely on the amount above Rs. 7,500. The Madras High Court subsequently held, in Greenwood Owners Association, that only the excess over Rs. 7,500 is taxable, and associations now follow that judicial position.
Practical effect: Chennai apartment associations should apply the High Court position carefully and keep member-wise workings ready for departmental scrutiny.
K.P. Mozika v. Oil and Natural Gas Corporation Ltd — Supreme Court, Civil Appeal No. 3548 of 2017, judgment dated 09-01-2024 · 2024-01-09
The Supreme Court examined contracts for supplying cranes, tankers and vehicles to ONGC. It held that a transfer of the right to use goods requires the customer to obtain effective control and legal right to use the goods to the exclusion of the owner. Where the owner retains the operator, control and responsibility, the arrangement is a service contract and not a deemed sale. Sales tax or VAT was therefore not attracted; service tax was.
How we apply it: Chennai transport, crane and equipment hire businesses should draft contracts carefully, since who controls the asset decides whether GST applies as a supply of service or of goods.
