Mathur MMDA is the Housing Board and MMDA township laid out in numbered main, cross and serial streets off Kamarajar Salai, between the Inner Ring Road and Madhavaram Milk Colony Road. Contractors, fabricators, tanker operators and labour suppliers serving the Manali petrochemical belt at MFL and CPCL sit alongside colony supermarkets, bakeries and hardware shops. Works-contract classification, TDS under Section 51 from PSU buyers and GSTR-2B mismatches dominate the compliance load. Years of working in and around Mathur MMDA 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 Manali and Manali New Town, 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.
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.
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 Mathur MMDA are never held up by a compliance gap at the gate.
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.
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.
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.
GSTR-1 requires four-digit HSN reporting for turnover up to Rs.5 crore and six digits above it, and a wrong code often means a wrong rate. We verify the classification of what you actually supply, so your invoices and returns rest on defensible codes.
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.

Rs.7,999/year
Practical outcomes our clients measure us by.
Getting IGST versus CGST and SGST right at the invoice stage spares you the painful cycle of paying the correct head again and pursuing a refund of the amount paid under the wrong one.
With the LUT filed at the start of each financial year and refund claims tracked to credit, exporters supply without blocking funds in IGST and recover accumulated credit on schedule.
Statutory windows such as thirty days for an ASMT-11 reply are tracked from the day a notice arrives, so responses go in on time, complete, and with your best case properly presented.
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.
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.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
4th Cross Street is a residential street in Mathur MMDA, about 550 m north of the centre of Mathur MMDA.

For GST purposes an address on 4th Cross Street falls under the Chennai North CGST Commissionerate, and the Mathur MMDA pincode is 600068.

Circular No. 247/04/2025-GST · 2025-02-14
Following the 55th GST Council meeting, CBIC clarified disputed classifications: ready-to-eat salted popcorn is taxable at 5 per cent (12 per cent if pre-packaged and labelled) while caramelised popcorn falls at 18 per cent as sugar confectionery; autoclaved aerated concrete blocks with over 50 per cent fly ash content attract 12 per cent; and dried pepper supplied by an agriculturist remains exempt. Past periods were regularised on an as-is-where-is basis to prevent retrospective demands.
Practical effect: Food processors and building-material traders should re-check product classifications against this circular, since regularisation protects past periods but the clarified rates bind future supplies.
Goodwill Industrial Canteen - AAR Tamil Nadu, Order No. TN/09/AAR/2018, dated 30 August 2018 · 2018-08-30
The applicant prepared food and served it in the canteens of client companies at their premises. It sought the rate applicable to this arrangement. The Authority held that the supply of food and beverages on the premises of an industrial undertaking was taxable at 18 percent up to 26 July 2018 and at 5 percent from 27 July 2018, when the restaurant service entry was amended to cover canteens at offices and factories, the concessional rate being available without input tax credit.
Practical effect: Chennai canteen contractors should bill factory and office canteens at 5 percent and forgo input tax credit on their purchases.
38th GST Council Meeting, New Delhi — 18 December 2019 · 2019-12-18
The Council waived late fee for taxpayers who furnished all pending statements of outward supplies in GSTR-1 for the tax periods from July 2017 to November 2019, provided they were filed by 10 January 2020. It also decided that e-way bill generation would be blocked for taxpayers who had not filed GSTR-1 for two tax periods, extending the blocking mechanism that already applied to GSTR-3B defaulters. Standard operating procedures were prescribed for officers dealing with non-filers, and Grievance Redressal Committees were set up at zonal and state level.
How we apply it: GSTR-1 default now carries its own e-way bill block, so filing GSTR-3B alone is not enough to keep despatches moving.
