The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Iyyappanthangal permanently ahead of both, delivering GSTR-1 & GSTR-3B Monthly Filing from Rs.749 with reconciliation, senior review and WhatsApp acknowledgements as standard.
We serve businesses on and around Bharathiyar Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

If you operate in Iyyappanthangal, GST deadlines arrive with the same force as anywhere in Chennai — GSTR-1 by the 11th, GSTR-3B by the 20th. Iyyappanthangal sits on Mount Poonamallee Road beside its MTC bus depot, in the hospital shadow of the Porur medical belt, with pharmacies, diagnostic collection centres, supermarkets and apartment builders filling the frontage towards Kattupakkam and Mangadu. Builders selling under-construction flats at the 1 and 5 per cent rates without input tax credit, and pharmacies handling 5, 12 and 18 per cent medicine slabs, drive most GST queries. We provide GSTR-1 & GSTR-3B Monthly Filing to businesses across Iyyappanthangal and the adjoining Porur and Kattupakkam localities, maintaining a compliance calendar for every client so due dates are met without last-minute panic, late fees or interest at 18 percent per annum.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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 Iyyappanthangal are comfortable with, and keeps written communication simple and jargon-free.
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.
Quarterly filing still demands monthly attention — IFF uploads so your buyers see their credit on time, and tax payment through PMT-06 by the 25th for the first two months of each quarter. We run that monthly rhythm so QRMP saves you effort without creating gaps.
Winding up attracts its own GST obligations — the cancellation application, reversal of credit on closing stock, and the final return in GSTR-10 within three months. We close registrations properly so a business you shut in Iyyappanthangal never writes back to you as a demand years later.
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.
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.
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.
Each period you receive a simple computation showing output tax, credit utilised and net cash payable, so GST becomes a number you understand and question rather than a figure you accept blindly.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
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.
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 |
|---|---|---|
| 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. |
| Input tax credit | Purchase register matched against GSTR-2B each period, with defaulting suppliers chased so eligible credit is actually captured. | Credit claimed from books alone; mismatches with GSTR-2B mean lost credit or excess claims that invite departmental queries. |
| 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. |
| 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. |
| 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. |
| 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. |
Bharathiyar Street is a residential street in Iyyappanthangal, about 1.1 km north of the centre of Iyyappanthangal. The same consultant covers the streets immediately around it — Santosh Bai Street (about 200 m); Vivekanander Street (about 250 m); subbiyah nagar (about 250 m); Mahatma Gandhi Street (about 350 m) — so a site visit on Bharathiyar Street can usually be combined with other work in Iyyappanthangal on the same trip. For GST purposes an address on Bharathiyar Street falls under the Chennai Outer CGST Commissionerate, and the Iyyappanthangal pincode is 600056.

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.
GSTN Advisory, 2021 — negative liability appearing in Form GSTR-4 filed by composition taxpayers · 2021
Composition taxpayers who left Table 6 of the annual return GSTR-4 blank found that the tax already paid through Form CMP-08 was treated as an excess payment, creating a negative liability that was then adjusted against later quarters. GSTN clarified that outward supply and reverse charge figures must be entered in Table 6 even though the tax has already been paid, and arranged for wrongly created negative balances to be reversed.
What to do about it: Composition dealers in Chennai must complete Table 6 of GSTR-4 each year, or the portal will show a false credit and later recover it.
Navbharat Imports - AAR Tamil Nadu, Advance Ruling No. 35/AAR/2021, dated 30 September 2021 · 2021-09-30
The importer sold a range of children's toys, some containing electronic circuits and some working purely mechanically. It asked for the correct rate on each. The Authority held that toys containing electronic components attract 18 percent under the residual entry for electronic toys, irrespective of how those components are used, so children's scooters and smart tricycles with lights and music are taxed at 18 percent, while toys that work without electronics remain at 12 percent.
Why this matters: Chennai toy traders must classify item by item, because a single electronic component moves a product from 12 to 18 percent.
