Choosing GSTR-1 & GSTR-3B Monthly Filing in Kovilambakkam is ultimately an act of trust: you are handing over sales figures, purchase records and portal access. Kovilambakkam straddles Medavakkam Main Road and the Pallavaram - Thoraipakkam Radial Road near Eachangadu Junction and the Keelkattalai Flyover, with apartment promoters, tile and hardware showrooms, timber depots, packers-and-movers and car workshops along Ezhumalai Road and Sathya Nagar Main Road. Promoters here mishandle the affordable-housing value cap and the input credit reversal on flats left unsold at completion certificate. We earn that trust the unglamorous way — fixed fees honoured, drafts approved by you before filing, acknowledgements shared the same day, and strict confidentiality throughout. Clients across Kovilambakkam, Keelkattalai and Madipakkam have stayed with us for years on precisely this basis.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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.
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.
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.
Most GST notices trace back to mismatches between GSTR-1, GSTR-3B and GSTR-2B. We reconcile these before filing, not after a notice arrives, so your returns are internally consistent and the most common triggers for ASMT-10 scrutiny simply never appear.
If your GSTR-1 and GSTR-3B start drifting apart, if a large supplier stops filing, or if your turnover approaches the e-invoice threshold, we flag it to you immediately. Early warnings from our side are cheaper than departmental letters later.
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.
The hours you or your accountant spent wrestling with the portal, JSON errors and reconciliations every month return to sales, operations and customers, while trained hands manage the compliance in the background.
Funding rounds, partnerships and business sales all begin with a compliance check. A clean, documented GST history lets you clear that scrutiny quickly instead of watching a deal stall over old filing gaps.
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.
When a query or verification comes, you respond through a professional who deals with the department regularly, in the department's own language and format, instead of facing an officer's letter alone.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
10th Street is a residential street in Kovilambakkam, about 600 m south-east of the centre of Kovilambakkam. The same consultant covers the streets immediately around it — 3rd Cross Street (about 200 m); 1st Main Road (about 250 m); Susila Nagar 1st Street (about 250 m); E.V.R. Periyar Road (about 300 m) — so a site visit on 10th Street can usually be combined with other work in Kovilambakkam on the same trip. For GST purposes an address on 10th Street falls under the Chennai South CGST Commissionerate, and the Kovilambakkam pincode is 600129.

GST law moves through notifications, circulars and court decisions. These are the ones changing how filings are prepared right now.
Circular No. 163/19/2021-GST, dated 6 October 2021 · 2021-10-06
Following the 45th GST Council meeting, CBIC settled several long-running classification quarrels. Exemption for fresh fruit and nuts covers only produce that has not been dried; once dried, they move to the taxable schedule. Tamarind seeds, copra as distinct from edible coconut, pure mehendi paste without additives, scented and flavoured sweet supari, brewers' spent grain and distillers' grains were each assigned a rate, and the position on renewable energy project valuation was restated.
Why this matters: Provision stores and dry-fruit traders in Chennai should re-check whether their stock is fresh or dried, because that single fact decides between nil and a taxable rate.
Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, Schedule I, Chapters 50 to 63 · 2025-09-17
Under the new Schedule I, woven fabrics of silk, wool, cotton, other vegetable fibres, man-made filaments and man-made staple fibres, knitted and crocheted fabrics, sewing thread of man-made filaments and staple fibres, and worn clothing and rags all attract five per cent. Man-made fibre and yarn, which had long been taxed higher than the cloth made from them, were also brought down, largely correcting the inverted duty structure that had troubled the Tamil Nadu textile belt since 2017.
Why this matters: Fabric traders and garment units charge five per cent across the chain, which should shrink credit accumulation and reduce dependence on inverted duty refunds.
Megha Engineering and Infrastructures Ltd v. Commissioner of Central Tax — Telangana High Court, judgment dated 18 April 2019 · 2019-04-18
The taxpayer filed GSTR-3B late and paid interest only on the net cash portion of the tax. The High Court held that on the language of Section 50 as it then stood, interest ran on the gross liability, because input tax credit is credited to the ledger only when the return is filed. The decision caused wide concern in trade, and Parliament later amended Section 50 with retrospective effect from 1 July 2017 to charge interest only on the cash component in most late-return cases.
What it means for you: For late returns, interest is now generally computed on the cash portion only — if an older notice demands interest on gross tax, rely on the retrospective proviso to Section 50.
