One WhatsApp message is how most of our client relationships began. Send yours today and have GSTR-1 & GSTR-3B Monthly Filing in Iyyappanthangal handled end to end from Rs.749 — fee confirmed in writing first, documents straight from your phone, acknowledgement the day we file.
We serve businesses on and around Mangadu Road — 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.
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. When businesses of this kind evaluate GSTR-1 & GSTR-3B Monthly Filing, the real question is not price alone but who answers when something goes wrong. We serve Iyyappanthangal, Porur and Kattupakkam on a standing commitment: responses within the same working day, senior scrutiny before every submission, and continued support if the department ever writes back on work carrying our preparation.
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.
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 Iyyappanthangal would otherwise read about after it lapsed reaches our clients in time.
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.
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.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Iyyappanthangal. We know how local proper officers examine registrations, what supporting documents they routinely call for, and how to present a file so it moves without repeated queries.
From filing the LUT in RFD-11 at the start of each financial year to preparing RFD-01 refund claims with complete annexures, we know what makes a refund file move. Exporters and inverted-duty businesses come to us specifically for this.
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.
Timeline: Filed before the 11th and 20th of every month · No hidden charges · GST invoice provided
Rs.7,999/year
Practical outcomes our clients measure us by.
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.
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.
Interest on delayed GST payment runs at 18 percent per annum, which is costlier than most working capital finance. Timely computation and payment through our calendar keeps that meter permanently at zero.
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.
Illness, travel or a family function no longer threatens a deadline. With a standing external process holding your calendar and data trail, filings proceed on schedule whether or not you are at your desk.
Because monthly data is reconciled as it happens, GSTR-9 preparation before the 31 December due date becomes a review exercise rather than a painful reconstruction of twelve untidy months.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
GST law moves through notifications, circulars and court decisions. These are the ones changing how filings are prepared right now.
M/s. Sun Dye Chem v. Assistant Commissioner (ST) — Madras High Court, W.P. No. 29676 of 2019, decided 6 October 2020 (Anita Sumanth J.) · 2020-10-06
The dealer inadvertently reported supplies under the wrong tax heads in its GSTR-1 and GSTR-3B, with the result that its customers could not claim the credit. The statutory window for amendment had closed. The Madras High Court permitted rectification of the returns for the relevant period, reasoning that the error was bona fide, the revenue suffered no loss, and the mechanism that would have allowed the taxpayer to detect the mismatch (the auto-populated matching forms) had never been made operational.
What it means for you: If a genuine head-of-tax or classification error in your GST returns has blocked your customer's credit, the Madras High Court route to rectification is available even after the ordinary time limit has passed.
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.
What to do about it: 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.
WABCO India Ltd - AAR Tamil Nadu, Order No. TN/10/AAR/2018, dated 27 September 2018 · 2018-09-27
The manufacturer supplied electrical wiring harness, essentially electrical wire with connectors at both ends, used in motor vehicles, and asked whether it should be classified as a motor vehicle part or as insulated electrical conductors. The Authority classified the product under heading 8544, which covers insulated wire and cable fitted with connectors, taxable at 9 percent central tax and 9 percent State tax following Notification No. 41/2017-Central Tax (Rate) dated 14 November 2017, the earlier rate having been higher.
What to do about it: Chennai auto component makers should classify by the tariff description of the article itself, not by the vehicle it eventually goes into.
