Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Late fees, blocked credit and mismatch notices cost far more than professional help ever will. We complete GSTR-1 & GSTR-3B Monthly Filing for Karapakkam businesses from Rs.749, matching every figure against portal data before anything reaches the department.
We serve businesses on and around Nadu Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.
Share your number — a senior GST consultant calls you back within 30 minutes.
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 commercial character shapes the GST questions we see from Karapakkam every week — registrations, monthly returns, credit mismatches and departmental queries. We deliver GSTR-1 & GSTR-3B Monthly Filing for businesses in Karapakkam, and clients also reach us from Thoraipakkam and Sholinganallur nearby. Documents move over WhatsApp, drafts are approved before filing, and a senior consultant reviews every submission, so distance from our office never dilutes the quality of the work.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
You deal with one accountable person who knows your business, your turnover pattern and your filing history. No repeating your story to a new voice every month, and no file falling between two desks when a deadline is approaching.
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.
From filing the LUT in RFD-11 at the start of each financial year to preparing RFD-01 refund claims with complete annexures, we know what makes a refund file move. Exporters and inverted-duty businesses come to us specifically for this.
New GSTIN applications, core field amendments through REG-14, additional places of business — we prepare complete, query-resistant applications the first time. Clean paperwork is the difference between smooth approval and weeks lost answering clarification memos from the department.
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.
Your work is executed by trained GST staff working under direct senior supervision, not passed to interns learning on your file. The person preparing your return understands reverse charge, blocked credits and place of supply, because getting these wrong costs you money.
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.

Rs.7,999/year
Practical outcomes our clients measure us by.
Interest on delayed GST payment runs at 18 percent per annum, which is costlier than most working capital finance. Timely computation and payment through our calendar keeps that meter permanently at zero.
Your billing staff are guided on invoice fields, rates and series discipline, so mistakes are prevented where they originate — at the counter — instead of being repaired later in the returns.
You know your expected GST outflow days before the 20th, not on the night of filing. That advance visibility lets you plan payments, collections and bank balances instead of scrambling for funds at the deadline.
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.
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.
Late-fee waivers and amnesty windows notified by the GST Council are applied to your history within their deadlines, capturing reliefs that most businesses only hear about once the window has already closed.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| Record keeping | Every return, challan, acknowledgement and working paper archived in an organised folder, retrievable in minutes years later. | Documents scattered across email, downloads and old phones; assembling records for a bank or an audit takes days. |
| 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. |
| Keeping up with changes | Rate changes, portal updates and new thresholds such as the Rs.5 crore e-invoice limit are tracked by us and applied to your case proactively. | Changes are discovered after the fact — often through a rejected filing, a blocked e-way bill or a departmental letter. |
| 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. |
Nadu Street is a residential street in Karapakkam, about 1.3 km south-east of the centre of Karapakkam. The same consultant covers the streets immediately around it — Velunayakkar Street (about 0 m); Gangaiamman Koil Street (about 100 m); Vembuli Nayakkar Street (about 100 m); Indira Gandhi Main Road (about 150 m) — so a site visit on Nadu Street can usually be combined with other work in Karapakkam on the same trip. For GST purposes an address on Nadu Street falls under the Chennai South CGST Commissionerate, and the Karapakkam pincode is 600097.

9th GST Council Meeting, New Delhi — 16 January 2017 (Signed Minutes, Agenda Item 5) · 2017-01-16
With the revised model law still to be brought back to the Council, the fitment of rates incomplete and taxpayers needing time to configure their accounting systems, the Council unanimously agreed to extend the GST rollout date to 1 July 2017. Maharashtra, Assam and Bihar had pressed for 1 April 2017, Assam adding that changing the tax regime in the middle of a financial year was undesirable, but the Chairperson observed that the legal and rate work would spill into March 2017 and that an April deadline had become a major challenge. Tamil Nadu and Karnataka supported 1 July 2017 as the more practical date.
Practical effect: GST law in India runs from 1 July 2017, so the first return periods, the first annual return and all transitional credit deadlines are measured from that date.
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.
What to do about it: Update your billing software's HSN masters so every item carries a valid 4 or 6 digit code that matches the portal dropdown.
Entry 1, Notification No. 13/2017-Central Tax (Rate) dated 28.06.2017 · 2017-06-28
Entry 1 makes the recipient liable to pay tax on services supplied by a goods transport agency in respect of transportation of goods by road, where the recipient falls in a specified class. That class includes any factory, society, co-operative society, registered person, body corporate, partnership firm and casual taxable person located in the taxable territory. The tax is payable in cash and, subject to normal conditions, is available as input tax credit. Reverse charge does not apply where the transporter has validly opted to pay under forward charge.
What it means for you: Every registered Chennai business that pays a lorry transporter with a consignment note must self-pay GST at 5 per cent on the freight unless the transporter has opted for forward charge.
