GSTR-1 & GSTR-3B Monthly Filing in Korukkupet does not have to mean portal errors, guesswork and due-date tension. For a fixed fee starting Rs.749, an accountable Chennai practice prepares, reconciles, reviews and files — and remains answerable long after the acknowledgement arrives.
We serve businesses on and around Kumalamman Koil Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Korukkupet is defined by the oil marketing company terminals off Thiruvottiyur High Road and Ennore High Road, the Korukkupet goods shed and the Cochrane Basin Road level crossing. Tanker fleet owners, terminal contractors, clearing agents and the Kalmandapam Road trading rows work around petroleum products staying outside GST, blocked input credit on such supplies, and reverse charge on inward goods transport. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Korukkupet follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Old Washermanpet and Tondiarpet run on the same process, entirely over WhatsApp if they prefer.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
GSTR-1 by the 11th, GSTR-3B by the 20th, CMP-08 by the 18th after each quarter — we maintain a compliance calendar for every client and start chasing your data well before the due date, so late fees never enter the picture.
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.
A new GSTIN comes with obligations nobody explains at approval — the invoice series rules, displaying the registration certificate and GSTIN at your premises, and the first return cycle. We walk new registrants in Korukkupet through each of these so month one starts correctly.
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.
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.
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.
Tax positions, rate choices and credit calls are documented as they are made, so if a question arises years later, the reasoning and evidence are on file rather than in someone's fading memory.
Filed returns, challans, reconciliations and working papers are archived in order from day one. If an audit or departmental verification comes, your file is ready the same week, not assembled in a panic.
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.
Continuous filing protects you from the suspension and cancellation proceedings that hit chronic non-filers, so your registration, e-way bill access and ability to issue tax invoices are never suddenly cut off.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Kumalamman Koil Street is a secondary arterial road in Korukkupet, about 1.5 km north-east of the centre of Korukkupet. The same consultant covers the streets immediately around it — Pilliyar Koil Street (about 100 m); Varadharaja Perumal Koil Street (about 200 m); Jeevarathinam Road (about 300 m); Sennaiamman Koil Street (about 350 m) — so a site visit on Kumalamman Koil Street can usually be combined with other work in Korukkupet on the same trip. For GST purposes an address on Kumalamman Koil Street falls under the Chennai North CGST Commissionerate, and the Korukkupet pincode is 600021.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
Circular No. 200/12/2023-GST, dated 1 August 2023 · 2023-08-01
Giving effect to the 50th GST Council decisions, CBIC clarified that un-fried and uncooked snack pellets manufactured by extrusion are classifiable under tariff item 1905 90 30 and attract five per cent with effect from 27 July 2023, and that fish soluble paste moved from eighteen to five per cent from the same date. Imitation zari thread or yarn made from metallised polyester or plastic film was placed at five per cent, and past periods were regularised on an as-is basis.
What it means for you: Snack and zari manufacturers in and around Chennai got both a lower rate and protection for past periods, so old demands on these items should be contested with this circular.
30th GST Council Meeting (video conference) — 28 September 2018 (PIB Release ID 1547891) · 2018-09-28
Meeting shortly after the Kerala floods, the Council discussed that State's proposal to impose a cess on SGST to fund rehabilitation and flood-related works. Because GST had removed the States' independent power to levy such a cess, the Council constituted a seven-member Group of Ministers convened by the Deputy Chief Minister of Bihar, with members from Assam, Kerala, Maharashtra, Odisha, Punjab and Uttarakhand, to examine modalities for revenue mobilisation in case of natural calamities and disasters, reporting by 31 October 2018.
How we apply it: This process produced the Kerala flood cess of 2019, the only State-specific GST cess so far, and set the template for how any similar Tamil Nadu levy would have to be approved.
GSTN Advisory dated 14 November 2023 — input tax credit reversal under Rule 37A of the CGST Rules for FY 2022-23 · 2023-11-14
Rule 37A requires a buyer to reverse input tax credit where the supplier reported the invoice in GSTR-1 but did not file the GSTR-3B for that tax period by 30 September following the end of the financial year. The reversal must be made in the GSTR-3B filed on or before 30 November. GSTN made supplier-wise details of such invoices available on the portal and advised taxpayers to complete the reversal for FY 2022-23 by 30 November 2023. The credit can be reclaimed once the supplier files the pending return.
How we apply it: Run a supplier compliance check every October, because credit from a defaulting supplier must be reversed by 30 November or carries interest.
