Finding dependable GSTR-1 & GSTR-3B Monthly Filing in Sembium usually means choosing between a distant online portal and an overloaded local accountant. Sembium straddles Paper Mills Road, Madhavaram High Road and Erukkancheri High Road, feeding the Perambur Carriage Works with fabrication shops, rubber and hosiery units, hardware and timber dealers. Bunder Garden Main Street, Melpatti Ponappa Street and Market Street hold provision wholesalers, sweet stalls and lorry booking agents, and the Carriage Works Road sheds house body builders. Transporters issuing consignment notes, reverse charge on freight and e-way bill expiry on Moolakadai bound loads are the standing pain points. We offer a third option: a professional Chennai GST practice that treats Sembium, Perambur and Agaram as home ground, responds the same working day, files ahead of deadlines, and stands behind its work if a notice ever arrives on a return we prepared.
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.
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.
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.
GST is confusing enough without a language barrier. Our team explains notices, tax positions and filing requirements in plain Tamil or English, whichever you and your staff in Sembium are comfortable with, and keeps written communication simple and jargon-free.
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.
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 Sembium regularly visit us for registrations, notice discussions and annual return reviews.
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.
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.
When GST knowledge lives inside a single staff member, their resignation becomes a compliance crisis. With our firm as the standing process, your filings continue uninterrupted regardless of internal staff changes.
Correct e-way bills matched to correct invoices mean your consignments clear roadside inspections cleanly, avoiding detention proceedings whose penalties can far exceed the tax on the goods being carried.
The hours you or your accountant spent wrestling with the portal, JSON errors and reconciliations every month return to sales, operations and customers, while trained hands manage the compliance in the background.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| Record keeping | Every return, challan, acknowledgement and working paper archived in an organised folder, retrievable in minutes years later. | Documents scattered across email, downloads and old phones; assembling records for a bank or an audit takes days. |

GSTN Advisory dated 7 June 2025 — non-editable auto-populated liability in GSTR-3B · 2025-06-07
After an October 2024 advisory and a January 2025 deferment, GSTN confirmed that from the July 2025 tax period the auto-populated outward tax liability in GSTR-3B, drawn from GSTR-1, IFF or GSTR-1A, is hard-locked and cannot be edited manually while filing. Any correction to sales figures must be made through GSTR-1A before GSTR-3B is filed. The change is intended to end mismatches between GSTR-1 and GSTR-3B.
Why this matters: Reconcile sales data before filing GSTR-1 each month, since GSTR-3B can no longer be adjusted at the last minute.
Circular No. 225/19/2024-GST · 2024-07-11
Building on the earlier corporate guarantee circular, the Board clarified that the special valuation rule in Rule 28(2) applies to guarantees issued or renewed on or after 26 October 2023, and that the one per cent value is to be read as one per cent per annum of the guarantee amount, apportioned where the guarantee runs for a shorter period. It also confirmed that where the recipient is eligible for full input tax credit, the value declared in the invoice is deemed to be the open market value.
What to do about it: Chennai promoters and holding companies giving guarantees for group borrowings should compute the value annually and, where the borrower takes full credit, can adopt the invoice value.
Notification No. 9/2025-Central Tax (Rate) · 2025-09-17
Implementing the 56th GST Council's rate restructuring, this notification superseded Notification 1/2017-Central Tax (Rate) and prescribed the new goods rate schedule effective 22 September 2025. The 12 and 28 per cent slabs were largely abolished: most daily-use and 12 per cent goods moved to 5 per cent, most 28 per cent goods including consumer durables moved to 18 per cent, and a 40 per cent rate was reserved for a narrow list of sin and luxury goods, with compensation cess subsumed.
Why this matters: Reprice products, update billing software rate masters and review transition stock credits from 22 September 2025, since almost every trader's rate schedule changed under GST 2.0.
