Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Late fees, blocked credit and mismatch notices cost far more than professional help ever will. We complete GSTR-1 & GSTR-3B Monthly Filing for Ambattur businesses from Rs.749, matching every figure against portal data before anything reaches the department.
We serve businesses on and around Ambattur Industrial Estate — 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.
Ambattur hosts one of South India's largest small-scale industrial estates, where thousands of engineering, auto component, garment and fabrication units operate across the North and South phases off MTH Road and Ambattur-Red Hills Road. Job work movements between units demand disciplined ITC-04 and delivery challan records, while exporters and units crossing Rs.5 crore turnover must manage LUT filings and e-invoicing. That commercial character shapes the GST questions we see from Ambattur every week — registrations, monthly returns, credit mismatches and departmental queries. We deliver GSTR-1 & GSTR-3B Monthly Filing for businesses in Ambattur, and clients also reach us from Avadi and Padi nearby. Documents move over WhatsApp, drafts are approved before filing, and a senior consultant reviews every submission, so distance from our office never dilutes the quality of the work.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
GST is confusing enough without a language barrier. Our team explains notices, tax positions and filing requirements in plain Tamil or English, whichever you and your staff in Ambattur are comfortable with, and keeps written communication simple and jargon-free.
You receive a WhatsApp message when documents are received, when the draft is ready for your approval, and when the return or application is filed, along with the acknowledgement. You never have to call and ask what is happening with your file.
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.
OTP failures, DSC errors, stuck submissions on due-date evenings — we deal with the GST portal daily and know the workarounds. When the site misbehaves on the 20th, our team keeps retrying and escalating so your return still goes through.
The annual return and, where turnover crosses Rs.5 crore, the self-certified reconciliation statement in GSTR-9C are prepared by the same team that filed your monthly returns. Nothing about your year has to be rediscovered or explained to a stranger in December.
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.
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.
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.
Sales returns, discounts and price revisions are adjusted through properly reported credit notes within the statutory window, so you never keep paying tax on turnover you have already reversed.
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.
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.
| 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. |
| 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. |
| 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. |
| Due-date tracking | A maintained compliance calendar with internal cut-offs days before the 11th and the 20th; we chase you for data, not the other way around. | Deadlines remembered from memory or phone alarms; one busy week and the return slips past the due date. |
| 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. |
Real notifications, rulings and case law our consultants track — and apply to client filings and notice replies.
GSTN Advisory dated 7 June 2025 — barring of GST returns after three years (Finance Act, 2023; Notification No. 28/2023-Central Tax) · 2025-06-07
Implementing the Finance Act, 2023 amendments to Sections 37, 39, 44 and 52, notified by Notification No. 28/2023-Central Tax, GSTN advised that from the July 2025 tax period the portal blocks filing of GST returns once three years have passed from their due date. The bar covers GSTR-1, GSTR-1A, GSTR-3B, GSTR-4, GSTR-5, GSTR-5A, GSTR-6, GSTR-7, GSTR-8 and GSTR-9. Taxpayers with old pending returns were urged to reconcile their records and file before the returns became permanently time-barred on the portal.
What it means for you: Clear every pending old return now, because once the three-year window closes the portal will not accept the return and registration consequences follow.
Circular No. 200/12/2023-GST, dated 1 August 2023 · 2023-08-01
Giving effect to the 50th GST Council decisions, CBIC clarified that un-fried and uncooked snack pellets manufactured by extrusion are classifiable under tariff item 1905 90 30 and attract five per cent with effect from 27 July 2023, and that fish soluble paste moved from eighteen to five per cent from the same date. Imitation zari thread or yarn made from metallised polyester or plastic film was placed at five per cent, and past periods were regularised on an as-is basis.
What it means for you: Snack and zari manufacturers in and around Chennai got both a lower rate and protection for past periods, so old demands on these items should be contested with this circular.
Commissioner of CGST and Central Excise v. Edelweiss Financial Services Ltd — Supreme Court, order dated 17-03-2023 dismissing the department's appeal against the CESTAT order · 2023-03-17
The Supreme Court dismissed the department's appeal and confirmed that where a holding company issues a corporate guarantee for its group companies without charging any consideration, no service tax is leviable. A taxable service requires consideration, and where none flows, the charge fails. Under GST the position has since been altered by a specific valuation rule for corporate guarantees between related persons, so the current position must be checked separately.
How we apply it: Chennai group companies giving guarantees to each other should review the current GST valuation rule, since the earlier no-consideration argument no longer holds under GST.
