Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
GSTR-1 & GSTR-3B Monthly Filing in Mandaveli does not have to mean portal errors, guesswork and due-date tension. For a fixed fee starting Rs.749, an accountable Chennai practice prepares, reconciles, reviews and files — and remains answerable long after the acknowledgement arrives.
We serve businesses on and around Bharathy Nagar — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

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. We have supported businesses of exactly this profile with GSTR-1 & GSTR-3B Monthly Filing across Mandaveli for years, along with clients from Mylapore and Raja Annamalaipuram. The engagement is simple: one point of contact, a clear fee, documents over WhatsApp or in person at our Chennai office, and senior review before anything is submitted on the portal. What you get in return is clean filings, archived records and far fewer reasons for the department to write to you.
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.
New GSTIN applications, core field amendments through REG-14, additional places of business — we prepare complete, query-resistant applications the first time. Clean paperwork is the difference between smooth approval and weeks lost answering clarification memos from the department.
Traders, manufacturers, contractors, e-commerce sellers, professionals and service exporters — we have handled GST for all of them. Whatever mix of goods and services your Mandaveli business supplies, the rate, classification and place-of-supply questions have almost certainly crossed our desk before.
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.
Whenever the GST Council notifies a late-fee waiver or an amnesty window for pending returns or old demands, we check every client's history against it and act within the deadline. Relief that businesses in Mandaveli would otherwise read about after it lapsed reaches our clients in time.
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.
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.
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.
Large buyers check vendor GST compliance before releasing payments and renewing contracts. A clean filing record with timely GSTR-1 uploads keeps your invoices reflecting in their GSTR-2B and your payments unblocked.
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.
Rates, reverse charge, place of supply and blocked credits are applied correctly at the preparation stage, so you neither overpay tax you do not owe nor underpay and invite demands with penalty later.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Bharathy Nagar is a residential street in Mandaveli, about 550 m east of the centre of Mandaveli.

GSTN Advisory dated 7 June 2025 — non-editable auto-populated liability in GSTR-3B · 2025-06-07
After an October 2024 advisory and a January 2025 deferment, GSTN confirmed that from the July 2025 tax period the auto-populated outward tax liability in GSTR-3B, drawn from GSTR-1, IFF or GSTR-1A, is hard-locked and cannot be edited manually while filing. Any correction to sales figures must be made through GSTR-1A before GSTR-3B is filed. The change is intended to end mismatches between GSTR-1 and GSTR-3B.
How we apply it: Reconcile sales data before filing GSTR-1 each month, since GSTR-3B can no longer be adjusted at the last minute.
Jindal Stainless Ltd v. State of Haryana — Supreme Court, nine-judge Bench, (2017) 12 SCC 1, judgment dated 11-11-2016 · 2016-11-11
The Supreme Court held that a tax is not per se a restriction on the freedom of trade and commerce guaranteed by Article 301 of the Constitution. Only a discriminatory tax that favours local goods over goods from other States is hit. The judicially created concept of compensatory tax was discarded as having no constitutional basis. State entry tax laws were largely upheld, subject to the test of discrimination.
What to do about it: Chennai businesses challenging a State levy must show actual discrimination against outside goods, not merely that the levy burdens interstate trade.
1st GST Council Meeting, New Delhi — 22-23 September 2016 (Signed Minutes, Agenda Item 3) · 2016-09-23
At its very first meeting the Council debated exemption thresholds ranging from Rs 10 lakh to Rs 25 lakh and finally agreed that a business would not need GST registration until its aggregate turnover crossed Rs 20 lakh. For the eleven Special Category States listed in Article 279A of the Constitution, the threshold was set at Rs 10 lakh. The Chairperson recorded that the figure would be reviewed after five years, once the compensation guarantee to States had run its course.
What it means for you: The Rs 20 lakh figure that still governs whether a small Chennai service business must register was settled at this meeting and has been the starting point for every later threshold change.
