The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Mogappair 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 1st Avenue — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

Mogappair, officially Dr. J.J. Nagar, is a healthcare and residential hub where the Madras Medical Mission hospital, multi-speciality clinics, diagnostic labs and pharmacies line Ambattur Industrial Estate Road and the East and West blocks. Hospitals and clinics supplying exempt healthcare alongside taxable pharmacy and canteen sales must apportion input tax credit between the two, the locality's most frequent GST question. Years of working in and around Mogappair 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 Ambattur and Anna Nagar, 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.
We match your purchase register against GSTR-2B every period, follow up on invoices your suppliers have not uploaded, and ensure every rupee of eligible input tax credit is claimed. Clients routinely recover credit they were silently losing under self-filing.
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 Mogappair 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.
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.
You are told the full fee before we begin, in writing. No surprise additions for uploads, revisions or acknowledgements. Government fees and taxes, where applicable, are shown separately, so businesses in Mogappair always know exactly what the engagement costs them.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
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.
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.
When a business winds up, proper cancellation and a timely final return ensure the file is genuinely closed, so no demand or late-fee computation resurfaces against you long after the shutters came down.
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.
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.
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.
New branches, new product lines and interstate sales all carry GST consequences. With standing professional support, you expand knowing registrations, invoicing and returns will keep pace with the business.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
1st Avenue is a secondary arterial road in Mogappair, about 550 m south-west of the centre of Mogappair. The same consultant covers the streets immediately around it — Ambattur Estate Road (about 50 m); 2nd Cross Main Road (about 400 m); 10th Street (about 450 m); 11th Street (about 500 m) — so a site visit on 1st Avenue can usually be combined with other work in Mogappair on the same trip. For GST purposes an address on 1st Avenue falls under the Chennai North CGST Commissionerate, and the Mogappair pincode is 600037.

Pentacle Plant Machineries (P) Ltd v. Office of the GST Council — Madras High Court, W.P. No. 1022 of 2020, decided 23 February 2021 (Anita Sumanth J.) · 2021-02-23
The supplier keyed in the customer's Uttar Pradesh GST number instead of the Andhra Pradesh one while filing GSTR-1, and the correction window had lapsed. The Madras High Court allowed the writ petition and directed that the return be permitted to be amended, describing the mistake as a bona fide human error. The Court observed that assessees should not be prejudiced from availing credit they are otherwise legitimately entitled to, particularly where the matching forms were never notified.
What to do about it: A typographical GSTIN error that has cost your buyer their credit is curable — do not simply write off the credit as lost because the portal has closed the amendment window.
4th GST Council Meeting, New Delhi — 3-4 November 2016 (Signed Minutes, Agenda Item 3) · 2016-11-03
Summing up a long debate over five-band and six-band options, the Chairperson proposed and the Council accepted a structure with one exempt category covering food grains and similar essentials, a lower rate of five per cent for goods consumed by vulnerable sections, standard rates of 12 and 18 per cent, and a higher slab of 28 per cent. A committee of officers was directed to fit individual goods and services into those slabs. Proposals for a 40 per cent slab were rejected.
What it means for you: Every rate dispute a Chennai business faces today traces back to this four-slab architecture and to the fitment exercise it launched.
Notification No. 83/2020-Central Tax · 2020-11-10
From January 2021 the outward supply statement in Form GSTR-1 became due on the 11th day of the month following the tax period for monthly filers. For registered persons furnishing GSTR-1 quarterly under the new scheme, the statement became due on the 13th day of the month following the quarter. This replaced the earlier practice of notifying due dates a few months at a time and gave the return calendar a stable shape that has continued since.
Practical effect: The 11th and the 13th are the fixed GSTR-1 dates for a Chennai business, and missing them delays credit for every customer you supply.
