Every locality in Chennai has its own commercial rhythm, and Perumbakkam is no exception. Perumbakkam has grown along Semmozhi Salai and Nookampalayam Road, anchored by Gleneagles Global Health City and large gated apartment projects. Builders, interior contractors, diagnostic labs, pharmacies, supermarkets and packers-and-movers dominate the trade here. Developers face the concessional 1 percent and 5 percent housing rates with their domestic procurement condition, alongside reverse charge on unregistered purchases and TDS credit under Section 51. Our practice has shaped its New GST Registration work around exactly these realities, serving clients in Perumbakkam as well as Medavakkam and Pallikaranai. Registrations, returns, refunds and notice replies are handled by one accountable team, with fees fixed in writing before work begins and every filing reconciled against portal data before it is submitted.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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 Perumbakkam are never held up by a compliance gap at the gate.
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.
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.
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.
Most GST notices trace back to mismatches between GSTR-1, GSTR-3B and GSTR-2B. We reconcile these before filing, not after a notice arrives, so your returns are internally consistent and the most common triggers for ASMT-10 scrutiny simply never appear.
Your cash ledger, credit ledger and liability register are reviewed regularly, not just at filing time. Excess balances are flagged for use or refund, and where a genuine slip surfaces, a voluntary payment through DRC-03 settles it before it can mature into a notice.
You share PAN, Aadhaar, photographs, address proof and bank details over WhatsApp or email. We review each document against portal requirements and flag anything that could trigger an officer query.
We draft Form GST REG-01 with the correct business constitution, principal place of business, HSN or SAC codes and authorised signatory details, then share a summary for your confirmation.
The application is filed on the GST portal and we guide the authorised signatory through Aadhaar OTP authentication, which speeds up approval and usually avoids physical verification of premises.
We track the ARN daily. If the officer issues a notice in Form REG-03 seeking clarification, we draft and file the reply in Form REG-04 within the permitted time.
Once approved, we download your registration certificate in Form REG-06, help set up portal login credentials, and brief you on invoice format, return due dates and e-way bill obligations.
Send these on WhatsApp (+91 - 9600 606 444) and we take it forward the same day.
Timeline: 3-7 working days · No hidden charges · GST invoice provided
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.
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.
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.
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.
Each period you receive a simple computation showing output tax, credit utilised and net cash payable, so GST becomes a number you understand and question rather than a figure you accept blindly.
| 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. |
| 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. |
| 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. |
| 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. |
Anandhammal Nagar Main road is a residential street in Perumbakkam, about 1.2 km east of the centre of Perumbakkam. The same consultant covers the streets immediately around it — First Main Road (about 100 m); Semmozhi Salai (about 300 m); Pudhu Nagar MGR street (about 750 m); Kakkanji Street (about 850 m) — so a site visit on Anandhammal Nagar Main road can usually be combined with other work in Perumbakkam on the same trip. For GST purposes an address on Anandhammal Nagar Main road falls under the Chennai South CGST Commissionerate, and the Perumbakkam pincode is 600100.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
We track every notification, circular and judgment that changes a filing position, so your returns and replies reflect the current law.
Notification No. 38/2021-Central Tax · 2021-12-21
The Aadhaar authentication requirements inserted earlier by the Eighth Amendment Rules had been left to take effect from a date to be notified. This notification appointed 1 January 2022 as that date, so that from the beginning of 2022 a refund application, a revocation application and an integrated tax refund on exports all became conditional on completed Aadhaar authentication and on a PAN-linked bank account. Applications filed without these steps are simply not processed on the portal.
What it means for you: From January 2022 onwards Aadhaar authentication is a gating requirement, so it should be completed at the registration stage rather than when a refund is urgently needed.
GSTN Advisory dated 1 November 2025 — simplified registration scheme under Rule 14A · 2025-11-01
GSTN operationalised the optional simplified registration scheme under Rule 14A of the CGST Rules from 1 November 2025. Applicants whose self-assessed output tax liability, across CGST, SGST, IGST and cess, does not exceed Rs 2.5 lakh per month can opt in while filing REG-01 and receive registration within three working days, subject to mandatory Aadhaar authentication of the primary authorised signatory and at least one promoter or partner.
Practical effect: Small Chennai businesses starting out can opt for Rule 14A registration to begin billing within days instead of waiting through full verification.
44th GST Council Meeting (video conferencing) — 12 June 2021 · 2021-06-12
Acting on a Group of Ministers report, the Council cut rates on COVID relief goods until 30 September 2021. Tocilizumab and Amphotericin B moved to nil, while Remdesivir and anti-coagulants such as heparin were reduced to 5 per cent. Medical grade oxygen, oxygen concentrators, ventilators, BiPAP machines, COVID testing kits and specified diagnostic kits all moved from 12 to 5 per cent. Pulse oximeters, hand sanitiser, temperature check equipment and crematorium furnaces moved to 5 per cent, and ambulances from 28 to 12 per cent.
Why this matters: These were temporary rates with a hard expiry, so suppliers must be able to show that concessional invoices fall inside the notified relief period.
