GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Kelambakkam commands the junction where the Vandalur-Kelambakkam Road meets Old Mahabalipuram Road, anchored by Chettinad Health City's hospital and university campuses and ringed by new apartment projects spreading towards Pudupakkam. Hospitals mixing exempt healthcare with taxable pharmacy and canteen sales must apportion input tax credit, and land promoters converting farm parcels into layouts need clarity on which part of their consideration attracts GST. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Kelambakkam follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Siruseri and Padur run on the same process, entirely over WhatsApp if they prefer.
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.
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.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
If a query, ASMT-10 scrutiny notice or DRC-01 arrives on a return we filed, we stand behind our work and help you draft the reply. You are not left alone with a departmental letter and a thirty-day clock ticking against you.
You receive a WhatsApp message when documents are received, when the draft is ready for your approval, and when the return or application is filed, along with the acknowledgement. You never have to call and ask what is happening with your file.
You are told the full fee before we begin, in writing. No surprise additions for uploads, revisions or acknowledgements. Government fees and taxes, where applicable, are shown separately, so businesses in Kelambakkam always know exactly what the engagement costs them.
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.

Rs.7,999/year
Practical outcomes our clients measure us by.
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.
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.
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.
Sales returns, discounts and price revisions are adjusted through properly reported credit notes within the statutory window, so you never keep paying tax on turnover you have already reversed.
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.
Late-fee waivers and amnesty windows notified by the GST Council are applied to your history within their deadlines, capturing reliefs that most businesses only hear about once the window has already closed.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
Circular No. 99/18/2019-GST dated 23 April 2019 · 2019-04-23
Following Removal of Difficulty Order No. 05/2019-Central Tax, CBIC clarified that a person whose registration was cancelled on or before 31 March 2019 for non-filing of returns could apply for revocation up to 22 July 2019. Where cancellation took effect from the order date, all returns up to that date had to be filed first. Where it was cancelled retrospectively, returns for the whole period from the effective date of cancellation had to be furnished within thirty days of the revocation order.
What to do about it: This was the first revocation amnesty and set the pattern of every later one, so a Chennai business with a dormant cancelled GSTIN should watch for such windows.
Union of India v. Bharti Airtel Ltd — Supreme Court, 2021 · 2021-10-28
Bharti Airtel sought to rectify its GSTR-3B for July-September 2017 to claim refund of about Rs 923 crore excess cash paid, blaming the non-operational GSTR-2A at the time. The Supreme Court set aside the Delhi High Court order permitting rectification, holding that returns can only be corrected in the period in which errors are noticed, as the law then stood, and that taxpayers must self-assess from their own books, not the portal.
What it means for you: File GSTR-3B accurately the first time — correct discovered errors in the current period per the prescribed mechanism rather than expecting retrospective revision of old returns.
Notification No. 28/2023-Central Tax · 2023-07-31
This notification appointed 1 October 2023 as the date for most GST amendments of the Finance Act 2023. The most consequential change bars taxpayers from filing GSTR-1, GSTR-3B, GSTR-9 and GSTR-8 after three years from their due date. The GST portal began actually blocking such time-barred returns from the July 2025 tax period, permanently freezing any unfiled compliance older than three years along with the credit flowing from it.
What it means for you: Any return more than three years past its due date can no longer be filed at all, so clear historic backlogs immediately rather than assuming they can be regularised later.
