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. From a first registration to the annual return, the full range of GSTR-1 & GSTR-3B Monthly Filing is available to Kolathur businesses without stepping far from the shop or office — documents travel over WhatsApp, and our Chennai premises are open to anyone who prefers a face-to-face discussion. We serve Villivakkam and Perambur on the same footing, applying one rule everywhere: reconcile before filing, file before the due date, and keep the client informed at every stage.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Kolathur. 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.
New GSTIN applications, core field amendments through REG-14, additional places of business — we prepare complete, query-resistant applications the first time. Clean paperwork is the difference between smooth approval and weeks lost answering clarification memos from the department.
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.
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.
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.
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.
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.
Filed returns, challans, reconciliations and working papers are archived in order from day one. If an audit or departmental verification comes, your file is ready the same week, not assembled in a panic.
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.
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.
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.
You know your expected GST outflow days before the 20th, not on the night of filing. That advance visibility lets you plan payments, collections and bank balances instead of scrambling for funds at the deadline.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| Input tax credit | Purchase register matched against GSTR-2B each period, with defaulting suppliers chased so eligible credit is actually captured. | Credit claimed from books alone; mismatches with GSTR-2B mean lost credit or excess claims that invite departmental queries. |

Saro Enterprises - AAR Tamil Nadu (2018), upheld by AAAR Tamil Nadu, order dated 6 February 2019 · 2018
The applicant made polypropylene and recycled plastic trays used by farmers to raise paddy and vegetable seedlings, and argued that they were agricultural implements. The Authority held that the trays are other articles of plastic under heading 3926 90 99 and are taxable at 9 percent central tax and 9 percent State tax. Use in agriculture does not by itself bring a product within the exempt agricultural implements entry, and the material and the tariff description prevail over the end use.
Practical effect: Chennai suppliers to the farm sector cannot assume exemption merely because the buyer uses the product in agriculture.
Mahadeo Construction Co. v. Union of India — Jharkhand High Court, W.P.(T) No. 3517 of 2019, judgment dated 21 April 2020, reported at [2020] 116 taxmann.com 262 (Jharkhand) · 2020-04-21
The department issued recovery notices for interest under Section 50 without any adjudication, treating the interest as automatically payable. The High Court held that although interest liability under Section 50 is automatic in principle, its computation and quantum are not. Where the taxpayer disputes the liability, the department must first initiate adjudication proceedings under Section 73 or 74 and pass an order before resorting to recovery under Section 79.
Practical effect: A bare recovery letter for interest, without a show cause notice and order, can be challenged if you genuinely dispute the amount.
GSTN Advisory dated 23 August 2024 — introduction of the RCM Liability/ITC Statement · 2024-08-23
GSTN introduced a new RCM Liability and ITC Statement on the portal so that reverse charge tax declared in Table 3.1(d) of GSTR-3B can be matched against the corresponding credit claimed in Table 4A(2) and 4A(3). It applies from the August 2024 tax period for monthly filers and from the July to September 2024 quarter for taxpayers under the quarterly scheme. Taxpayers were required to report an opening balance of reverse charge liability paid but credit not yet claimed, or credit claimed without payment, within the window announced by GSTN.
Why this matters: Reconcile reverse charge payments with the credit taken every month, since the department can now see an RCM ledger for your GSTIN.
