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 have supported businesses of exactly this profile with GSTR-1 & GSTR-3B Monthly Filing across Kolathur for years, along with clients from Villivakkam and Perambur. The engagement is simple: one point of contact, a clear fee, documents over WhatsApp or in person at our Chennai office, and senior review before anything is submitted on the portal. What you get in return is clean filings, archived records and far fewer reasons for the department to write to you.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
GSTR-3B late fees run at Rs.50 per day and interest at 18 percent per annum on unpaid tax. Our internal cut-offs sit days ahead of statutory due dates precisely so that our clients never hand the department a rupee they did not owe.
Your work is executed by trained GST staff working under direct senior supervision, not passed to interns learning on your file. The person preparing your return understands reverse charge, blocked credits and place of supply, because getting these wrong costs you money.
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.
Goods sent to job workers must move on delivery challans, return within the statutory period, and be reported in ITC-04. We track every outward and return leg for manufacturing clients in Kolathur, so inputs sent out for processing never quietly convert into a deemed supply carrying tax and interest.
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.
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.
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.
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.
With returns filed ahead of the statutory due dates every period, the Rs.50-per-day GSTR-3B late fee simply stops appearing in your life, and the money stays in your business where it belongs.
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.
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.
Complete RFD-01 applications with proper statements and annexures move through the system faster and attract fewer deficiency memos, which means export and inverted-duty refunds reach your bank account sooner.
New branches, new product lines and interstate sales all carry GST consequences. With standing professional support, you expand knowing registrations, invoicing and returns will keep pace with the business.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| Time cost | Roughly an hour a month to send data and approve drafts; the portal work, reconciliation and follow-up are ours. | Hours every month lost to portal errors, JSON files, OTP failures and reworking figures — usually on the due date itself. |
| 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. |
| 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. |
| 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. |
Paper Mills Road is a secondary arterial road in Kolathur, about 400 m north-west of the centre of Kolathur. The same consultant covers the streets immediately around it — Kumaran Nagar Main Road (about 450 m); Kolathur Road (about 500 m); Balaji Nagar Main Road (about 550 m); 2nd Cross Street (about 700 m) — so a site visit on Paper Mills Road can usually be combined with other work in Kolathur on the same trip. For GST purposes an address on Paper Mills Road falls under the Chennai North CGST Commissionerate, and the Kolathur pincode is 600099.

Kone Elevator India (P) Ltd v. State of Tamil Nadu — Supreme Court, Constitution Bench, (2014) 7 SCC 1, judgment dated 06-05-2014 · 2014-05-06
A five-judge Bench overruled the earlier view and held that a composite contract for manufacture, supply and installation of a lift is a works contract, because the lift comes into existence as a functional unit only on installation at site. The dominant nature test was rejected for contracts falling within the deemed sale of works contracts. The composite character of such contracts is now the basis of works contract taxation under GST.
How we apply it: Chennai contractors doing supply-plus-installation work should classify the transaction as a works contract service under GST rather than splitting it into goods and labour.
Circular No. 142/12/2020-GST dated 9 October 2020 · 2020-10-09
As a Covid relief measure, the rule 36(4) credit restriction was not applied separately for each of the tax periods February to August 2020. CBIC clarified that the taxpayer must instead apply the restriction cumulatively for those seven months while filing the GSTR-3B for September 2020, comparing the aggregate credit taken with the aggregate credit reflected in GSTR-2A for that whole span, and reversing any excess in that return.
How we apply it: Any scrutiny of credit for the first Covid year must be tested cumulatively for February to August 2020, not month by month.
55th GST Council Meeting, Jaisalmer — 21 December 2024 · 2024-12-21
The 55th meeting reduced GST on fortified rice kernel (FRK) to 5 per cent regardless of end use, supporting public distribution fortification programmes. Gene therapy was fully exempted from GST, a major relief for patients of ultra-expensive treatments. Autoclaved aerated concrete (ACC) blocks containing more than 50 per cent fly ash content were classified under HS 6815 at 12 per cent. The Council also reduced the rate of compensation cess to 0.1 per cent on supplies to merchant exporters, bringing it on par with the concessional 0.1 per cent GST rate on such supplies.
Practical effect: Construction suppliers dealing in fly-ash-based AAC blocks should bill at 12 per cent and revisit classification disputes on past supplies.
