Every locality in Chennai has its own commercial rhythm, and Kolathur is no exception. 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. Our practice has shaped its GSTR-1 & GSTR-3B Monthly Filing work around exactly these realities, serving clients in Kolathur as well as Villivakkam and Perambur. Registrations, returns, refunds and notice replies are handled by one accountable team, with fees fixed in writing before work begins and every filing reconciled against portal data before it is submitted.
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.
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 Kolathur compete with each other; complete confidentiality is a condition of our work.
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.
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.
Most GST notices trace back to mismatches between GSTR-1, GSTR-3B and GSTR-2B. We reconcile these before filing, not after a notice arrives, so your returns are internally consistent and the most common triggers for ASMT-10 scrutiny simply never appear.
The annual return and, where turnover crosses Rs.5 crore, the self-certified reconciliation statement in GSTR-9C are prepared by the same team that filed your monthly returns. Nothing about your year has to be rediscovered or explained to a stranger in December.
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.
When a business winds up, proper cancellation and a timely final return ensure the file is genuinely closed, so no demand or late-fee computation resurfaces against you long after the shutters came down.
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.
Your billing staff are guided on invoice fields, rates and series discipline, so mistakes are prevented where they originate — at the counter — instead of being repaired later in the returns.
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.
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.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
We track every notification, circular and judgment that changes a filing position, so your returns and replies reflect the current law.
Bharat Sanchar Nigam Ltd v. Union of India — Supreme Court, (2006) 3 SCC 1, judgment dated 02-03-2006 · 2006-03-02
The Supreme Court held that the same transaction may have a goods aspect and a service aspect, and different legislatures may tax different aspects, but the same element cannot be taxed twice. A composite contract cannot be split into goods and services except in the cases specifically permitted by Article 366(29A), such as works contracts and catering. The dominant nature test was applied to decide the character of the contract.
What to do about it: Chennai businesses with bundled offerings should determine the dominant character of the supply, since that decides classification and rate under GST.
Notification No. 15/2021-Central Tax (Rate) dated 18.11.2021 · 2021-11-18
This notification removed the words governmental authority and government entity from the concessional works contract entries in the services rate notification. With effect from 1 January 2022, works contract services supplied to a governmental authority or a government entity ceased to enjoy the 12 per cent rate and moved to 18 per cent with input tax credit. Only supplies made directly to the Central Government, a State Government, a Union territory or a local authority continued at the concessional rate at that stage.
Practical effect: Chennai contractors working for boards, corporations and government companies moved to 18 per cent from 1 January 2022, and should have raised price-variation claims for contracts signed earlier.
GSTN Advisory, 2022 — Table 3.1.1 of Form GSTR-3B introduced by Notification No. 14/2022-Central Tax, dated 5 July 2022 · 2022
Table 3.1.1 was added to GSTR-3B so that supplies notified under Section 9(5), such as passenger transport, restaurant service supplied through an app, hotel accommodation and housekeeping, are reported separately. The e-commerce operator reports the value and pays the tax in row (i), while the underlying supplier reports the same value in row (ii) and pays nothing on it, so the turnover is not counted twice across the two returns.
How we apply it: Chennai restaurants and cab operators supplying through an app must still report those sales in Table 3.1.1(ii) even though the platform pays the tax.
