If you operate in Keelkattalai, GST deadlines arrive with the same force as anywhere in Chennai — GSTR-1 by the 11th, GSTR-3B by the 20th. Keelkattalai lies where Medavakkam Main Road meets the Pallavaram-Thoraipakkam 200 Feet Radial Road, its frontage carrying tile and sanitaryware showrooms, timber and hardware dealers, supermarkets and diagnostic labs that serve the apartment belt around Keelkattalai Lake. Dealers delivering materials to construction sites regularly trip on e-way bill requirements for consignments above Rs.50,000, and first-time registration for fast-growing retailers is routine work here. We provide GSTR-1 & GSTR-3B Monthly Filing to businesses across Keelkattalai and the adjoining Madipakkam and Kovilambakkam localities, maintaining a compliance calendar for every client so due dates are met without last-minute panic, late fees or interest at 18 percent per annum.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
If your GSTR-1 and GSTR-3B start drifting apart, if a large supplier stops filing, or if your turnover approaches the e-invoice threshold, we flag it to you immediately. Early warnings from our side are cheaper than departmental letters later.
Businesses with registrations in more than one State, or multiple branches under one PAN, face cross-charge, stock transfer and input service distribution questions that single-GSTIN firms never see. We keep all your registrations consistent with each other, not just compliant individually.
E-invoicing is mandatory once turnover crosses Rs.5 crore and e-way bills apply to goods movements above Rs.50,000. We set up, train and troubleshoot both systems, so your despatches from Keelkattalai are never held up by a compliance gap at the gate.
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.
A registration cancelled for non-filing is not the end of the road. We bring the pending returns up to date, clear the dues and file the revocation application in REG-21 within the permitted window, restoring suspended and cancelled GSTINs to active status.
Your cash ledger, credit ledger and liability register are reviewed regularly, not just at filing time. Excess balances are flagged for use or refund, and where a genuine slip surfaces, a voluntary payment through DRC-03 settles it before it can mature into a notice.
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.
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.
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.
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.
Advances received for services attract GST on receipt while advances for goods generally do not; applying this distinction correctly means you neither prepay tax unnecessarily nor omit a liability that surfaces later with interest.
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.
E-commerce platforms continuously validate seller GSTINs and filing status. A consistently compliant registration keeps your listings active and settlements flowing, with no sudden suspension of your online sales channel.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |

Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, Schedule II, Chapter 84 and 85 entries · 2025-09-17
Air conditioning machines, refrigerators, freezers and other refrigerating equipment, household and other dishwashing machines, vacuum cleaners, television sets including LCD and LED sets, computer monitors, set top boxes and projectors all sit in Schedule II at nine per cent central tax, giving eighteen per cent combined, from 22 September 2025. These goods had carried twenty-eight per cent since 2017, so the reduction of ten percentage points was the largest single consumer benefit of GST 2.0.
How we apply it: Electronics retailers had to reprice stock and re-issue price lists from 22 September 2025, and should retain evidence that the reduction was passed on to buyers.
21st GST Council Meeting, Hyderabad — 9 September 2017 (PIB Release ID 1502268) · 2017-09-09
Faced with widespread filing difficulties, the Council approved a revised schedule for the first tax period: GSTR-1 for July 2017 to 10 October (3 October for taxpayers above Rs 100 crore turnover), GSTR-2 to 31 October, GSTR-3 to 10 November and GSTR-6 to 13 October. Table 4 of GSTR-4 was not to be filled for the July-September quarter and GSTR-4A was dispensed with. GSTR-3B was to continue for August to December 2017.
Practical effect: The invoice-matching return cycle of GSTR-1, 2 and 3 collapsed almost immediately, and GSTR-3B became the permanent monthly filing every Chennai business now does.
GSTN Advisories dated 12 April 2023 and 6 May 2023 — time limit for reporting invoices on the Invoice Registration Portal · 2023-04-12
GSTN announced that taxpayers with aggregate annual turnover of one hundred crore rupees or more would be unable to report an invoice on the Invoice Registration Portal more than seven days after the document date, with effect from 1 May 2023. After representations the implementation was deferred by three months. The idea returned later as a thirty day reporting limit applying to taxpayers with turnover of ten crore rupees and above.
Practical effect: Large Chennai taxpayers should generate the invoice reference number on the day of billing rather than leaving e-invoicing to month end.
