Most of it happens without you leaving your shop counter. Share your documents on WhatsApp, approve the prepared draft, and your GSTR-1 & GSTR-3B Monthly Filing is completed on the portal from Rs.749 — by a Chennai team that businesses across Thirumangalam have relied on for years.
We serve businesses on and around Ambedkar Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

Thirumangalam junction, where Jawaharlal Nehru Salai meets Anna Nagar 2nd Avenue beside the metro station and VR Chennai mall, has become a showroom strip for jewellery, textiles, furniture and electronics chains spilling into Anna Nagar West Extension. High-volume B2C billing with occasional B2B orders makes correct GSTR-1 bifurcation and e-invoice applicability checks the daily compliance concern for retailers here. For businesses here, staying on the right side of GST is not optional — buyers check compliance, and the department's systems match every return. Our firm provides GSTR-1 & GSTR-3B Monthly Filing to clients across Thirumangalam and neighbouring Anna Nagar and Mogappair, combining Chennai jurisdiction familiarity with disciplined deadline tracking. Whether you run a shop, a service practice or a growing trading concern, we handle the portal work so you can stay focused on the business itself.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Winding up attracts its own GST obligations — the cancellation application, reversal of credit on closing stock, and the final return in GSTR-10 within three months. We close registrations properly so a business you shut in Thirumangalam never writes back to you as a demand years later.
A registration cancelled for non-filing is not the end of the road. We bring the pending returns up to date, clear the dues and file the revocation application in REG-21 within the permitted window, restoring suspended and cancelled GSTINs to active status.
Tally, Zoho Books, Busy, marketplace reports, plain Excel or even a handwritten bill book — we take your data in whatever form your Thirumangalam business already maintains it. You are never forced to buy new software or retrain staff just to become our client.
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.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Thirumangalam. We know how local proper officers examine registrations, what supporting documents they routinely call for, and how to present a file so it moves without repeated queries.
GST is confusing enough without a language barrier. Our team explains notices, tax positions and filing requirements in plain Tamil or English, whichever you and your staff in Thirumangalam are comfortable with, and keeps written communication simple and jargon-free.
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.
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.
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.
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.
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.
Correct, complete tax invoices signal a well-run business to customers, vendors and banks alike, quietly strengthening your credibility in every transaction where your paperwork is seen.
We spot suppliers who stop uploading invoices or filing returns and alert you before their default becomes your blocked credit, letting you recover amounts or switch vendors while the exposure is still small.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| When a notice arrives | A professional drafts the reply in the department's format and files it within the statutory window, such as thirty days for ASMT-11. | You face departmental language alone, and a missed reply deadline can convert a simple query into a demand with penalty. |
| 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. |
| 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. |
Ambedkar Street is a residential street in Thirumangalam, about 900 m west of the centre of Thirumangalam. The same consultant covers the streets immediately around it — V.O.C. Street (about 100 m); Anna Street (about 100 m); Rajaji Street (about 350 m); Kamarajar Street (about 400 m) — so a site visit on Ambedkar Street can usually be combined with other work in Thirumangalam on the same trip. For GST purposes an address on Ambedkar Street falls under the Chennai North CGST Commissionerate, and the Thirumangalam pincode is 600040.

Notification No. 03/2022-Central Tax (Rate) dated 13.07.2022 · 2022-07-13
Giving effect to the 47th GST Council's rate rationalisation, this notification raised the rate on works contract services supplied to the Central Government, State Government, Union territory and local authorities from 12 per cent to 18 per cent with input tax credit, applying from 18 July 2022. Several High Courts, including the Madras High Court, have since heard petitions by contractors seeking reimbursement of the differential tax from the awarding department on contracts priced before the change.
What it means for you: Chennai civil contractors with pre-July 2022 government tenders should pursue a differential-tax claim with the department rather than absorbing the 6 per cent increase.
GSTN Advisories No. 624 dated 27 September 2025 and No. 631 dated 17 October 2025 — IMS enhancements from the October 2025 tax period · 2025-10
GSTN enhanced the Invoice Management System from the October 2025 tax period. Recipients can now keep credit notes and specified records pending for one tax period instead of being forced to accept or reject them immediately, can declare the actual amount of input tax credit to be reduced when accepting a credit note where the credit was never availed or was already reversed, and can save remarks when rejecting or keeping a document pending. GSTR-2B can be recomputed after corrective action is taken.
Why this matters: Train your accounts team on the new pending and partial-reversal options so supplier credit notes do not strip more ITC than legally required.
11th GST Council Meeting, New Delhi — 4 March 2017 (PIB Release ID 1483622) · 2017-03-04
The Council approved the draft CGST and IGST Bills as vetted by the Law Ministry, clearing them for introduction in Parliament. The approved design provided for State-wise single registration, a single State-wise return covering intra-State, inter-State and export supplies, registration exemption below Rs 20 lakh turnover (Rs 10 lakh in Special Category States), a composition scheme up to Rs 50 lakh, broad input tax credit entitlement, and cross-utilisation of credit between CGST, SGST, UTGST and IGST in a prescribed order.
Why this matters: The structural features a Chennai business deals with every day, from one GSTIN per State to the credit set-off order, were locked in at this meeting.
