The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Sowcarpet 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 Kasi Chetty Street — 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.
Businesses in Sowcarpet looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. Sowcarpet along Mint Street is Chennai's Marwari and Gujarati trading quarter, dense with jewellery showrooms, textile wholesalers, dry fruit and grocery merchants, and private financiers around Kasi Chetty Street and Elephant Gate. Rate-sensitive gold billing, HSN-wise reporting in GSTR-1 and the bar on composition dealers making interstate sales make careful scheme selection and classification the core GST issue here. We serve this belt — including Mannady and Parrys (George Town) — with fixed fees quoted upfront, a written document checklist, and filings completed ahead of statutory due dates. Every acknowledgement is shared the day it is generated, and our support continues if the department raises any query on work we have filed.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Freight paid to transporters, advocate fees, imported services and other notified supplies attract GST under reverse charge, with self-invoicing where the supplier is unregistered. We maintain a running RCM check every period, because this is the liability self-filers most consistently miss.
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.
GSTR-1 requires four-digit HSN reporting for turnover up to Rs.5 crore and six digits above it, and a wrong code often means a wrong rate. We verify the classification of what you actually supply, so your invoices and returns rest on defensible codes.
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 Sowcarpet would otherwise read about after it lapsed reaches our clients in time.
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.
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.

Practical outcomes our clients measure us by.
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.
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.
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.
Your scheme choice — regular, composition or QRMP — is re-examined as turnover and margins change, so you are always paying under the structure that legitimately costs your business the least.
Because turnover in your GST returns is kept aligned with your accounts through the year, income tax filing and statutory audit proceed without the GST-versus-books mismatch queries that now surface routinely through data matching.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
| 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. |
| 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. |
| 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. |
| 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. |
| Annual return preparation | Monthly reconciliations roll naturally into GSTR-9, filed comfortably before 31 December with figures already agreed through the year. | Twelve months of unmatched data reconstructed in December, with differences discovered too late to be corrected cleanly. |
| 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. |

56th GST Council Meeting, New Delhi — 3 September 2025 · 2025-09-03
The 56th GST Council meeting approved the biggest structural reform since 2017, replacing the 5, 12, 18 and 28 per cent slabs with a two-rate structure — a 5 per cent merit rate and an 18 per cent standard rate — plus a 40 per cent de-merit rate for a narrow set of luxury and sin goods. Most items at 12 per cent moved to 5 per cent and most at 28 per cent moved to 18 per cent. The new rates took effect from 22 September 2025 and remain in force.
How we apply it: Every Chennai business had to re-map product rates, reprice stock and update billing software from 22 September 2025 — rate mistakes since then invite scrutiny notices.
Kone Elevator India (P) Ltd v. State of Tamil Nadu — Supreme Court, Constitution Bench, (2014) 7 SCC 1, judgment dated 06-05-2014 · 2014-05-06
A five-judge Bench overruled the earlier view and held that a composite contract for manufacture, supply and installation of a lift is a works contract, because the lift comes into existence as a functional unit only on installation at site. The dominant nature test was rejected for contracts falling within the deemed sale of works contracts. The composite character of such contracts is now the basis of works contract taxation under GST.
Why this matters: Chennai contractors doing supply-plus-installation work should classify the transaction as a works contract service under GST rather than splitting it into goods and labour.
Saro Enterprises - AAR Tamil Nadu (2018), upheld by AAAR Tamil Nadu, order dated 6 February 2019 · 2018
The applicant made polypropylene and recycled plastic trays used by farmers to raise paddy and vegetable seedlings, and argued that they were agricultural implements. The Authority held that the trays are other articles of plastic under heading 3926 90 99 and are taxable at 9 percent central tax and 9 percent State tax. Use in agriculture does not by itself bring a product within the exempt agricultural implements entry, and the material and the tariff description prevail over the end use.
Practical effect: Chennai suppliers to the farm sector cannot assume exemption merely because the buyer uses the product in agriculture.
