Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Whether you are a first-time registrant or an established trader, GSTR-1 & GSTR-3B Monthly Filing in Adambakkam deserves a specialist rather than a side job. From Rs.749, our GST-focused Chennai practice runs the entire process on written checklists and senior-reviewed submissions.
We serve businesses on and around 3rd Main Road — 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.
Adambakkam packs hardware, sanitaryware, electrical and provision trade into New Colony Main Road, Brindavan Nagar Main Road, Kakkan Nagar Main Road and Income Tax Main Road, with the Inner Ring Road and Velachery Main Road carrying goods towards Guindy and Ekkattuthangal. Job-work units and works-contract sub-contractors around the TNHB Colony and Dandeeswaram belt misjudge the twelve against eighteen per cent job-work rate and lose credit on delivery-challan movements. GST compliance in a market like Adambakkam rewards consistency — returns that match, credits that reconcile, and records that stand up to scrutiny. Our team provides GSTR-1 & GSTR-3B Monthly Filing to businesses throughout Adambakkam and nearby Nanganallur and Ullagaram on fixed, transparent fees. From the first document checklist to the final acknowledgement on WhatsApp, the process is structured so nothing depends on memory, luck or a due-date-evening scramble.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
GSTR-1 requires four-digit HSN reporting for turnover up to Rs.5 crore and six digits above it, and a wrong code often means a wrong rate. We verify the classification of what you actually supply, so your invoices and returns rest on defensible codes.
If a query, ASMT-10 scrutiny notice or DRC-01 arrives on a return we filed, we stand behind our work and help you draft the reply. You are not left alone with a departmental letter and a thirty-day clock ticking against you.
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.
You are told the full fee before we begin, in writing. No surprise additions for uploads, revisions or acknowledgements. Government fees and taxes, where applicable, are shown separately, so businesses in Adambakkam always know exactly what the engagement costs them.
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 Adambakkam compete with each other; complete confidentiality is a condition of our work.
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 Adambakkam never writes back to you as a demand years later.
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.
Timeline: Filed before the 11th and 20th of every month · No hidden charges · GST invoice provided
Rs.7,999/year
Practical outcomes our clients measure us by.
Advances received for services attract GST on receipt while advances for goods generally do not; applying this distinction correctly means you neither prepay tax unnecessarily nor omit a liability that surfaces later with interest.
E-commerce platforms continuously validate seller GSTINs and filing status. A consistently compliant registration keeps your listings active and settlements flowing, with no sudden suspension of your online sales channel.
The hours you or your accountant spent wrestling with the portal, JSON errors and reconciliations every month return to sales, operations and customers, while trained hands manage the compliance in the background.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
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.
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.
| 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. |
| 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. |
| 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. |
| Goods in transit | E-way bills generated correctly and matched to invoices, so consignments pass roadside inspections without detention or penalty. | A defective or missing e-way bill can mean detention at a checkpoint, with penalties that dwarf the tax on the consignment. |
| 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. |
| 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. |
3rd Main Road is a residential street in Adambakkam, about 1.3 km north of the centre of Adambakkam. The same consultant covers the streets immediately around it — 2nd Street (about 100 m); 38th Lane (about 150 m); 3rd Street (about 150 m); 2nd Avenue (about 150 m) — so a site visit on 3rd Main Road can usually be combined with other work in Adambakkam on the same trip. For GST purposes an address on 3rd Main Road falls under the Chennai South CGST Commissionerate, and the Adambakkam pincode is 600088.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.

1st GST Council Meeting, New Delhi — 22-23 September 2016 (Signed Minutes, Agenda Item 3) · 2016-09-23
At its very first meeting the Council debated exemption thresholds ranging from Rs 10 lakh to Rs 25 lakh and finally agreed that a business would not need GST registration until its aggregate turnover crossed Rs 20 lakh. For the eleven Special Category States listed in Article 279A of the Constitution, the threshold was set at Rs 10 lakh. The Chairperson recorded that the figure would be reviewed after five years, once the compensation guarantee to States had run its course.
How we apply it: The Rs 20 lakh figure that still governs whether a small Chennai service business must register was settled at this meeting and has been the starting point for every later threshold change.
Notification No. 15/2025-Central Tax · 2025-09-17
CBIC notified that registered persons with aggregate turnover up to Rs 2 crore are exempt from filing the annual return GSTR-9 for FY 2024-25 and onwards. Unlike the year-by-year exemptions issued for FY 2017-18 through FY 2023-24, this operates as a continuing exemption, removing the need for annual renotification. Small taxpayers therefore have certainty that only GSTR-1 and GSTR-3B, or the QRMP equivalents, constitute their regular compliance calendar.
Practical effect: Businesses under Rs 2 crore turnover are permanently outside the GSTR-9 net from FY 2024-25, though internal annual reconciliation remains prudent for scrutiny-readiness.
Tamil Nadu Water Investment Company Ltd - AAR Tamil Nadu, advance ruling reported at 2019 (2) TMI 187 · 2019
The Chennai company provided management consultancy and detailed project report services to the Chennai Metro Water Supply and Sewerage Board for water related projects. It asked whether the service attracted GST. The Authority held that the supply was a pure service with no supply of goods involved, rendered in relation to a function entrusted to a municipality, and was therefore exempt from GST under the entry covering pure services supplied to government and local authorities.
Practical effect: Chennai consultants on government water and civic projects should test the pure services exemption before adding GST to their invoices.
