Mandaveli is a dense middle-class trading strip along R.K. Mutt Road, where provision stores, sweet stalls, silk and readymade shops, banks and the MTC bus terminus serve Mylapore's southern flank, with the Mandaveli Market feeding daily vegetable trade. Most shops are family-run B2C businesses hovering near the Rs.40 lakh goods threshold, so registration timing, composition scheme choice and GSTR-3B late fees dominate consultations. For businesses here, staying on the right side of GST is not optional — buyers check compliance, and the department's systems match every return. Our firm provides GSTR-1 & GSTR-3B Monthly Filing to clients across Mandaveli and neighbouring Mylapore and Raja Annamalaipuram, combining Chennai jurisdiction familiarity with disciplined deadline tracking. Whether you run a shop, a service practice or a growing trading concern, we handle the portal work so you can stay focused on the business itself.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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 Mandaveli always know exactly what the engagement costs them.
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 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.
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.
GSTR-1 by the 11th, GSTR-3B by the 20th, CMP-08 by the 18th after each quarter — we maintain a compliance calendar for every client and start chasing your data well before the due date, so late fees never enter the picture.
Every new client receives a review of their recent returns before we file anything — unclaimed credit, GSTR-1 versus GSTR-3B drift, and exposures worth correcting quietly. Businesses in Mandaveli often discover in this first review exactly why their previous arrangement was costing them money.
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.
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.
With returns filed ahead of the statutory due dates every period, the Rs.50-per-day GSTR-3B late fee simply stops appearing in your life, and the money stays in your business where it belongs.
Your scheme choice — regular, composition or QRMP — is re-examined as turnover and margins change, so you are always paying under the structure that legitimately costs your business the least.
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.
Consistent, reconciled returns give the department's matching systems nothing to flag. Clients who move to us after years of self-filing typically see scrutiny queries and mismatch notices fall away within a few filing cycles.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Kandaswami Street is a residential street in Mandaveli, about 500 m south of the centre of Mandaveli. The same consultant covers the streets immediately around it — TP Scheme Road (about 50 m); Raja Street (about 100 m); Velayuda Raja Street (about 200 m); School View Road (about 200 m) — so a site visit on Kandaswami Street can usually be combined with other work in Mandaveli on the same trip. For GST purposes an address on Kandaswami Street falls under the Chennai North CGST Commissionerate, and the Mandaveli pincode is 600028.

Selected notifications, Council decisions and court rulings that practising consultants are applying to live cases.
M/s. Refex Industries Ltd v. Assistant Commissioner of CGST & Central Excise — Madras High Court, W.P. Nos. 23360 & 23361 of 2019, decided 6 January 2020 (Anita Sumanth J.) · 2020-01-06
The department demanded interest on the entire tax shown in belated GSTR-3B returns, including the part discharged from input tax credit. The Madras High Court held that interest under Section 50 is compensatory, and can be levied only on the belated cash payment of tax, not on input tax credit that was lying with the department all along. The proviso inserted in Section 50(1) was treated as curative and applicable to earlier periods as well.
How we apply it: A Chennai business that filed GSTR-3B late should verify that any interest demand is computed only on the cash component of the tax, and contest interest charged on the ITC-set-off portion.
Notification No. 84/2020-Central Tax · 2020-11-10
Registered persons whose aggregate turnover in the preceding financial year was up to Rs 5 crore, and who had filed the return for the preceding month, were notified as eligible to furnish GSTR-3B quarterly while paying tax monthly. The option is exercised on the common portal for each quarter within a specified window, and once exercised it continues for future periods until it is changed. Crossing Rs 5 crore during a year makes the person ineligible from the next quarter.
What to do about it: Most Chennai traders and professionals qualify for this scheme and can cut their GSTR-3B filings from twelve a year to four.
Circular No. 209/3/2024-GST · 2024-06-26
Clarifying the new clause (ca) of Section 10(1) of the IGST Act, CBIC stated that when goods are supplied to an unregistered person and the billing address differs from the delivery address, the place of supply is the delivery address recorded on the invoice. This principally affects e-commerce transactions, where a buyer may bill in one State and ship to another, and determines whether the seller charges CGST-SGST or IGST.
What it means for you: E-commerce sellers must configure invoicing so tax type follows the delivery address, not the billing address, to avoid wrong-tax demands and refund complications.
