Santhome stretches from the Light House end of Marina down Santhome High Road past San Thome Basilica, mixing schools such as St. Bede's, church-linked institutions, neighbourhood retail and the fishing settlement of Nochikuppam along Loop Road. Fresh fish sales are GST-exempt, but ice, packing and transport attract tax, so fisherfolk cooperatives and seafood sellers here need careful exempt-versus-taxable classification. Years of working in and around Santhome have shown us where GST trouble actually begins here — supplier defaults, classification doubts and deadlines lost in busy trading weeks. Our GSTR-1 & GSTR-3B Monthly Filing is built to close precisely those gaps, and the same team supports businesses in Mylapore and Foreshore Estate, each with one point of contact and a compliance calendar maintained on their behalf.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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.
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 Santhome compete with each other; complete confidentiality is a condition of our work.
Freight paid to transporters, advocate fees, imported services and other notified supplies attract GST under reverse charge, with self-invoicing where the supplier is unregistered. We maintain a running RCM check every period, because this is the liability self-filers most consistently miss.
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.
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.
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.
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.
Amounts deducted by government buyers as GST TDS and by marketplaces as TCS are accepted on the portal each period, so money withheld against your GSTIN actually reaches your cash ledger instead of lying unclaimed.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
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.
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.
Whether moving between composition and regular scheme, opting into QRMP, or crossing the e-invoice threshold at Rs.5 crore, transitions are planned in advance rather than discovered after a compliance breach.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
South Leith Castle Street is a residential street in Santhome, about 400 m south of the centre of Santhome. The same consultant covers the streets immediately around it — Leith Castle Centre Street (about 100 m); North Leith Castle Street (about 150 m); Madha Church Road (about 250 m); Jonehan Street (about 300 m) — so a site visit on South Leith Castle Street can usually be combined with other work in Santhome on the same trip. For GST purposes an address on South Leith Castle Street falls under the Chennai North CGST Commissionerate, and the Santhome pincode is 600004.

M/s. Lodha Roadways v. Deputy State Tax Officer — Madras High Court, W.P. No. 12595 of 2023, decided 24 April 2023 (Anita Sumanth J.) · 2023-04-24
A transporter sought release of detained goods. The Court dismissed the petition, holding that under Section 129 the entitlement to seek release of goods lies only with the owner, his agent or representative. The transporter's remedy is confined to release of the conveyance on payment of the penalty or one lakh rupees, whichever is less. Any claim about payment of tax on the consignment has to be pursued by the assessee who owns the goods, not by the carrier.
Why this matters: When a Chennai consignment is detained, the consignor or consignee must file the release application in its own name; letting the lorry operator do it will cost time.
GSTN Advisory dated 14 November 2023 — input tax credit reversal under Rule 37A of the CGST Rules for FY 2022-23 · 2023-11-14
Rule 37A requires a buyer to reverse input tax credit where the supplier reported the invoice in GSTR-1 but did not file the GSTR-3B for that tax period by 30 September following the end of the financial year. The reversal must be made in the GSTR-3B filed on or before 30 November. GSTN made supplier-wise details of such invoices available on the portal and advised taxpayers to complete the reversal for FY 2022-23 by 30 November 2023. The credit can be reclaimed once the supplier files the pending return.
How we apply it: Run a supplier compliance check every October, because credit from a defaulting supplier must be reversed by 30 November or carries interest.
Notification No. 33/2020-Central Tax · 2020-04-03
CBIC waived the late fee for furnishing the outward supply statement in Form GSTR-1 for the months of March, April and May 2020 and for the quarter ending 31 March 2020, provided the statement was filed on or before 30 June 2020. The relief covered both monthly and quarterly filers. Because GSTR-1 late fee is separate from GSTR-3B late fee, this notification had to be issued in addition to the GSTR-3B waiver of the same date.
What it means for you: A Chennai supplier who filed the March to May 2020 GSTR-1 by 30 June 2020 owes nothing by way of late fee, whatever the portal ledger may currently show.
