Our consultants provide GSTR-1 & GSTR-3B Monthly Filing to businesses across Iyyappanthangal starting at Rs.749. Every file is reconciled and senior-reviewed before submission, which is why our clients see far fewer departmental queries than they did while self-filing.

Finding dependable GSTR-1 & GSTR-3B Monthly Filing in Iyyappanthangal usually means choosing between a distant online portal and an overloaded local accountant. 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 offer a third option: a professional Chennai GST practice that treats Iyyappanthangal, Porur and Kattupakkam as home ground, responds the same working day, files ahead of deadlines, and stands behind its work if a notice ever arrives on a return we prepared.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
If a query, ASMT-10 scrutiny notice or DRC-01 arrives on a return we filed, we stand behind our work and help you draft the reply. You are not left alone with a departmental letter and a thirty-day clock ticking against you.
Your work is executed by trained GST staff working under direct senior supervision, not passed to interns learning on your file. The person preparing your return understands reverse charge, blocked credits and place of supply, because getting these wrong costs you money.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Late-fee waivers and amnesty windows notified by the GST Council are applied to your history within their deadlines, capturing reliefs that most businesses only hear about once the window has already closed.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| Goods in transit | E-way bills generated correctly and matched to invoices, so consignments pass roadside inspections without detention or penalty. | A defective or missing e-way bill can mean detention at a checkpoint, with penalties that dwarf the tax on the consignment. |
| 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. |
Positions we rely on when preparing filings and drafting replies — with the exact citation, so you can verify each one.
21st GST Council Meeting, Hyderabad — 9 September 2017 (PIB Release ID 1502268) · 2017-09-09
Faced with widespread filing difficulties, the Council approved a revised schedule for the first tax period: GSTR-1 for July 2017 to 10 October (3 October for taxpayers above Rs 100 crore turnover), GSTR-2 to 31 October, GSTR-3 to 10 November and GSTR-6 to 13 October. Table 4 of GSTR-4 was not to be filled for the July-September quarter and GSTR-4A was dispensed with. GSTR-3B was to continue for August to December 2017.
Practical effect: The invoice-matching return cycle of GSTR-1, 2 and 3 collapsed almost immediately, and GSTR-3B became the permanent monthly filing every Chennai business now does.
CBIC v. Aberdare Technologies (P) Ltd — Supreme Court, 2025 (SLP against Bombay HC order dated 29-07-2024 dismissed) · 2025-03-21
The Bombay High Court permitted Aberdare Technologies to correct bona fide clerical errors in its GST returns beyond the statutory deadline where there was no loss of revenue. Dismissing the department's SLP, the Supreme Court observed that human errors are normal, denying correction unjustifiably burdens taxpayers and benefits the department at their cost, and asked CBIC to re-examine the rigid timelines for rectifying returns since software limitations cannot defeat substantive rights.
Practical effect: If a genuine clerical mistake in GSTR-1 or GSTR-3B is blocking your customer's ITC or inflating your liability, courts now support rectification even beyond the deadline where revenue is not prejudiced.
CBIC Frequently Asked Questions on GST on pre-packaged and labelled goods, dated 17 July 2022 · 2022-07-17
A day before the change took effect, the Tax Research Unit issued FAQs explaining that the expression takes its meaning from the Legal Metrology Act, 2009 and covers commodities intended for retail sale in packs of up to twenty-five kilograms or twenty-five litres that must bear statutory declarations. A single package above that limit is not covered, nor are packs supplied to an industrial or institutional consumer. Loose sale from a large pack by a retailer does not attract the levy.
What it means for you: A fifty-kilogram rice bag sold as one package stays outside the levy, but the moment it is repacked into labelled retail bags of twenty-five kilograms or less, five per cent applies.
