The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in St. Thomas Mount permanently ahead of both, delivering GSTR-1 & GSTR-3B Monthly Filing from Rs.749 with reconciliation, senior review and WhatsApp acknowledgements as standard.
We serve businesses on and around Railway Station Road — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.
Share your number — a senior GST consultant calls you back within 30 minutes.
St. Thomas Mount combines the cantonment economy around Butt Road with airport-linked logistics, guest houses and retail on GST Road. Contractors and suppliers billing the Cantonment Board and defence establishments face 2 per cent GST TDS, which deductors report in GSTR-7 by the 10th, so vendors must accept and reconcile those credits monthly to avoid cash-flow leakage. From a first registration to the annual return, the full range of GSTR-1 & GSTR-3B Monthly Filing is available to St. Thomas Mount businesses without stepping far from the shop or office — documents travel over WhatsApp, and our Chennai premises are open to anyone who prefers a face-to-face discussion. We serve Alandur and Guindy on the same footing, applying one rule everywhere: reconcile before filing, file before the due date, and keep the client informed at every stage.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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 St. Thomas Mount regularly visit us for registrations, notice discussions and annual return reviews.
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.
No filing leaves our desk on a junior's judgement alone. A senior GST practitioner reviews your figures, ITC claims and tax computation before submission, so errors are caught at our table and not by the department months later through a notice.
When an ADT-01 audit intimation or a personal hearing date arrives, we compile the records, prepare the reconciliations and draft the submissions, and coordinate closely with your authorised representative. You walk into the proceeding prepared, not improvising in front of an officer.
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 St. Thomas Mount never leave marketplace deductions unclaimed.
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.
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.
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.
Continuous filing protects you from the suspension and cancellation proceedings that hit chronic non-filers, so your registration, e-way bill access and ability to issue tax invoices are never suddenly cut off.
Systematic GSTR-2B matching and supplier follow-up mean input tax credit that was leaking away under self-filing is captured each month, directly reducing the cash you pay out with every GSTR-3B.
A fixed professional fee is almost always cheaper than the combination of late fees, interest, lost credit and staff hours that informal, last-minute compliance quietly accumulates over a year.
Correct, complete tax invoices signal a well-run business to customers, vendors and banks alike, quietly strengthening your credibility in every transaction where your paperwork is seen.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |

Notification No. 57/2017-Central Tax dated 15.11.2017 · 2017-11-15
This notification allowed registered persons with an aggregate turnover of up to Rs 1.5 crore in the preceding or current financial year to furnish the statement of outward supplies in FORM GSTR-1 on a quarterly rather than monthly basis, and prescribed the quarterly due dates. It was the first structural concession recognising that monthly outward supply reporting was disproportionate for very small businesses.
How we apply it: This quarterly GSTR-1 concession is the direct ancestor of today's QRMP scheme, and many small Chennai businesses have been on a quarterly cycle continuously since this notification.
56th GST Council Meeting, New Delhi — 3 September 2025 · 2025-09-03
The 56th GST Council meeting approved the biggest structural reform since 2017, replacing the 5, 12, 18 and 28 per cent slabs with a two-rate structure — a 5 per cent merit rate and an 18 per cent standard rate — plus a 40 per cent de-merit rate for a narrow set of luxury and sin goods. Most items at 12 per cent moved to 5 per cent and most at 28 per cent moved to 18 per cent. The new rates took effect from 22 September 2025 and remain in force.
Practical effect: Every Chennai business had to re-map product rates, reprice stock and update billing software from 22 September 2025 — rate mistakes since then invite scrutiny notices.
Krishna Bhavan Foods and Sweets - AAR Tamil Nadu, Order No. TN/24/AAR/2021, dated 18 June 2021, upheld by AAAR Tamil Nadu, Order No. TN/AAAR/02/2022, dated 13 January 2022 · 2021-06-18
The applicant sold packaged ready to cook instant mixes for dosai, idli, tiffin items, sweets, health mix and porridge. It argued that these were only flours of cereals and pulses taxable at 5 percent. The Authority classified the products under heading 2106 90 as food preparations not elsewhere specified, attracting 18 percent GST, because the mixing and added ingredients took them out of the concessional flour entries. The Appellate Authority upheld that classification.
What to do about it: Chennai food manufacturers selling instant mixes should confirm whether the product is a plain flour or a preparation before applying 5 percent.
