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 Kolathur have relied on for years.
We serve businesses on and around Sri Ganesh Nagar — 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.
Businesses in Kolathur looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. Kolathur is India's best-known ornamental fish hub, with breeding farms and aquarium shops clustered off Red Hills Road near Retteri junction, alongside hardware stores and construction material suppliers serving fast-growing residential pockets like Poombuhar Nagar. Many fish breeders and online sellers cross the Rs.40 lakh goods threshold without realising it, making first-time registration and e-commerce reporting the local GST pain point. We serve this belt — including Villivakkam and Perambur — with fixed fees quoted upfront, a written document checklist, and filings completed ahead of statutory due dates. Every acknowledgement is shared the day it is generated, and our support continues if the department raises any query on work we have filed.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
A new GSTIN comes with obligations nobody explains at approval — the invoice series rules, displaying the registration certificate and GSTIN at your premises, and the first return cycle. We walk new registrants in Kolathur through each of these so month one starts correctly.
Sellers on Amazon, Flipkart and other marketplaces face a three-way match between marketplace reports, GSTR-1 and the TCS the operator deposits against your GSTIN. We reconcile all three every period and accept the TCS credit, so sellers in Kolathur never leave marketplace deductions unclaimed.
Quarterly filing still demands monthly attention — IFF uploads so your buyers see their credit on time, and tax payment through PMT-06 by the 25th for the first two months of each quarter. We run that monthly rhythm so QRMP saves you effort without creating gaps.
We are a Chennai firm with a physical office, not a faceless portal. If you prefer to sit across a table with your papers, you are welcome. Clients from Kolathur regularly visit us for registrations, notice discussions and annual return reviews.
Composition dealers have their own rulebook — CMP-08 every quarter, GSTR-4 annually by 30 June, bills of supply instead of tax invoices, and a turnover ceiling that must be watched. We handle each of these correctly so the scheme's simplicity never turns into a violation.
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.
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.
Loan applications and government tenders routinely demand GST returns and registration documents. With everything filed and archived properly, you can produce a complete compliance file within hours instead of days.
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.
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.
Funding rounds, partnerships and business sales all begin with a compliance check. A clean, documented GST history lets you clear that scrutiny quickly instead of watching a deal stall over old filing gaps.
Continuous filing protects you from the suspension and cancellation proceedings that hit chronic non-filers, so your registration, e-way bill access and ability to issue tax invoices are never suddenly cut off.
Whether moving between composition and regular scheme, opting into QRMP, or crossing the e-invoice threshold at Rs.5 crore, transitions are planned in advance rather than discovered after a compliance breach.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
30th GST Council Meeting (video conference) — 28 September 2018 (PIB Release ID 1547891) · 2018-09-28
Meeting shortly after the Kerala floods, the Council discussed that State's proposal to impose a cess on SGST to fund rehabilitation and flood-related works. Because GST had removed the States' independent power to levy such a cess, the Council constituted a seven-member Group of Ministers convened by the Deputy Chief Minister of Bihar, with members from Assam, Kerala, Maharashtra, Odisha, Punjab and Uttarakhand, to examine modalities for revenue mobilisation in case of natural calamities and disasters, reporting by 31 October 2018.
Practical effect: This process produced the Kerala flood cess of 2019, the only State-specific GST cess so far, and set the template for how any similar Tamil Nadu levy would have to be approved.
Star Engineers (India) (P) Ltd v. Union of India — Bombay High Court, Writ Petition No. 15368 of 2023, judgment dated 14 December 2023 · 2023-12-14
The company made bona fide clerical errors in its GSTR-1 which prevented its customer from taking credit, and the portal would not permit correction after the statutory deadline had passed. The High Court held that GST is a technology-driven regime intended to be taxpayer-friendly, that a genuine error causing no loss of revenue ought to be permitted to be corrected, and directed the authorities to allow rectification of the returns for the relevant period.
How we apply it: Where a GSTR-1 error is blocking your customer's credit, a rectification request supported by this judgment is worth making even after the statutory deadline.
Notification No. 08/2017-Central Tax (Rate) dated 28.06.2017 · 2017-06-28
Section 9(4) of the CGST Act as originally enacted made a registered person liable to pay tax under reverse charge on all inward supplies received from unregistered persons. This notification granted a de minimis exemption where the aggregate value of such supplies received from all unregistered suppliers did not exceed Rs 5,000 in a day. The exemption proved unworkable in practice and section 9(4) was soon suspended altogether.
What to do about it: This threshold only matters for the July to October 2017 period, and Chennai businesses still facing scrutiny for those months should check the daily aggregate rather than invoice-wise values.
