Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Most of it happens without you leaving your shop counter. Share your documents on WhatsApp, approve the prepared draft, and your New GST Registration is completed on the portal from Rs.1,499 — by a Chennai team that businesses across Sembium have relied on for years.
We serve businesses on and around Bunder Garden Main 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.
GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Sembium straddles Paper Mills Road, Madhavaram High Road and Erukkancheri High Road, feeding the Perambur Carriage Works with fabrication shops, rubber and hosiery units, hardware and timber dealers. Bunder Garden Main Street, Melpatti Ponappa Street and Market Street hold provision wholesalers, sweet stalls and lorry booking agents, and the Carriage Works Road sheds house body builders. Transporters issuing consignment notes, reverse charge on freight and e-way bill expiry on Moolakadai bound loads are the standing pain points. That is why our New GST Registration engagements in Sembium follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Perambur and Agaram run on the same process, entirely over WhatsApp if they prefer.
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.
In the days before the 11th and the 20th, our team runs extended hours and a strict internal queue, so a client who sends data late in the window is still filed on time. Peak-season crush at our end never becomes a late fee at yours.
If your GSTR-1 and GSTR-3B start drifting apart, if a large supplier stops filing, or if your turnover approaches the e-invoice threshold, we flag it to you immediately. Early warnings from our side are cheaper than departmental letters later.
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.
Your sales figures, supplier lists and login credentials are handled only by our engaged team, stored securely and never shared with any third party. Many of our clients in Sembium compete with each other; complete confidentiality is a condition of our work.
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.
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.
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.
Your scheme choice — regular, composition or QRMP — is re-examined as turnover and margins change, so you are always paying under the structure that legitimately costs your business the least.
Statutory windows such as thirty days for an ASMT-11 reply are tracked from the day a notice arrives, so responses go in on time, complete, and with your best case properly presented.
When a business winds up, proper cancellation and a timely final return ensure the file is genuinely closed, so no demand or late-fee computation resurfaces against you long after the shutters came down.
Illness, travel or a family function no longer threatens a deadline. With a standing external process holding your calendar and data trail, filings proceed on schedule whether or not you are at your desk.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
Bunder Garden Main Street is a residential street in Sembium, about 1.1 km south of the centre of Sembium. The same consultant covers the streets immediately around it — Tank Bund Road (about 100 m); Paper Mills Road (about 200 m); Kannabiraan Koil Street (about 200 m); Rajabather Street (about 250 m) — so a site visit on Bunder Garden Main Street can usually be combined with other work in Sembium on the same trip. For GST purposes an address on Bunder Garden Main Street falls under the Chennai North CGST Commissionerate, and the Sembium pincode is 600011.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
Tata Consultancy Services v. State of Andhra Pradesh — Supreme Court, (2005) 1 SCC 308, judgment dated 05-11-2004 · 2004-11-05
The Court examined whether canned or branded software sold on floppies and discs could be taxed as goods under sales tax law. It held that the term goods covers all types of movable property, tangible or intangible, provided the item can be abstracted, transmitted, transferred, delivered, stored and possessed. Branded software satisfies that test and is goods, even though the intellectual content is intangible. Customised software developed for a single customer stands on a different footing.
Practical effect: Chennai software and IT product businesses should classify off-the-shelf licences separately from bespoke development, since the goods or services character drives the rate, the place of supply and the e-invoice treatment.
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.
Circular No. 95/14/2019-GST dated 28 March 2019 · 2019-03-28
CBIC found that persons whose registration had been cancelled for non-compliance were applying for a brand new registration rather than seeking revocation. Officers were directed to examine every fresh application closely, to check whether the applicant had an earlier registration at the same place of business, and to reject the application under rule 9 if the true purpose was to avoid the pending returns and dues attached to the old registration.
What it means for you: If your Chennai GSTIN has been cancelled, apply for revocation and clear the arrears; taking a new number at the same premises will simply be refused.
