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.
In the days before the 11th and the 20th, our team runs extended hours and a strict internal queue, so a client who sends data late in the window is still filed on time. Peak-season crush at our end never becomes a late fee at yours.
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.
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.
You deal with one accountable person who knows your business, your turnover pattern and your filing history. No repeating your story to a new voice every month, and no file falling between two desks when a deadline is approaching.
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.
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 Kolathur 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.

Practical outcomes our clients measure us by.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
Illness, travel or a family function no longer threatens a deadline. With a standing external process holding your calendar and data trail, filings proceed on schedule whether or not you are at your desk.
Amounts deducted by government buyers as GST TDS and by marketplaces as TCS are accepted on the portal each period, so money withheld against your GSTIN actually reaches your cash ledger instead of lying unclaimed.
Where a genuine error is found in a past period, voluntary payment through DRC-03 before any notice issues closes the matter at minimal cost, instead of letting it ripen into a demand with penalty.
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.
Statutory windows such as thirty days for an ASMT-11 reply are tracked from the day a notice arrives, so responses go in on time, complete, and with your best case properly presented.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Red Hills Road is a main connecting road in Kolathur, about 2.2 km south-west of the centre of Kolathur. The same consultant covers the streets immediately around it — 31st Street (about 1.3 km); 30th Street (about 1.3 km); Bajanai Koil Street (about 1.3 km); 27th Street (about 1.4 km) — so a site visit on Red Hills Road can usually be combined with other work in Kolathur on the same trip. For GST purposes an address on Red Hills Road falls under the Chennai North CGST Commissionerate, and the Kolathur pincode is 600099.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
GSTN Advisories dated 11 April 2025 and 16 May 2025 — Table 3.2 of GSTR-3B · 2025-04-11
GSTN first advised that from the April 2025 period, auto-populated values in Table 3.2 of GSTR-3B, covering inter-state supplies to unregistered persons, composition taxpayers and UIN holders, would become non-editable, with corrections routed through GSTR-1A. After taxpayer representations, a 16 May 2025 advisory kept Table 3.2 editable for the time being. The locking was later subsumed in the broader hard-locking of GSTR-3B liability during 2025.
How we apply it: Report place-of-supply details correctly in GSTR-1 itself, since state-wise B2C figures in GSTR-3B are moving beyond manual correction.
Circular No. 26/26/2017-GST dated 29 December 2017 · 2017-12-29
This consolidated circular explained the return filing decisions of the 23rd GST Council meeting. It clarified the due dates, the quantum of late fee, and, most usefully, that errors in a GSTR-3B already filed cannot be revised but must be corrected by adjusting the figures in the return of a later month, with interest payable where tax was short paid. It also dealt with returns that were submitted but not filed because of portal problems.
How we apply it: The principle that GSTR-3B is corrected in a subsequent month rather than revised still governs every rectification a Chennai business makes today.
Rich Dairy Products (India) Pvt Ltd - AAR Tamil Nadu (2019), upheld by AAAR Tamil Nadu, Order No. TN/AAAR/01/2020 · 2019
The Namakkal manufacturer made carbonated beverages containing fruit juice and sought classification under the fruit pulp or fruit juice based drinks entry taxed at 12 percent. The Authority held that once carbon dioxide is added the product is classifiable under heading 2202 10 as waters containing added carbon dioxide and flavouring, and not as fruit juice under heading 2009, so the higher rate applicable to that entry along with compensation cess applies. The Appellate Authority upheld that view.
Practical effect: Chennai beverage makers must check whether the drink is carbonated before applying the 12 percent fruit drink rate.
