Most of it happens without you leaving your shop counter. Share your documents on WhatsApp, approve the prepared draft, and your GSTR-1 & GSTR-3B Monthly Filing is completed on the portal from Rs.749 — by a Chennai team that businesses across Korukkupet have relied on for years.
We serve businesses on and around Kannan 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.
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. GST compliance in a market like Korukkupet rewards consistency — returns that match, credits that reconcile, and records that stand up to scrutiny. Our team provides GSTR-1 & GSTR-3B Monthly Filing to businesses throughout Korukkupet and nearby Old Washermanpet and Tondiarpet on fixed, transparent fees. From the first document checklist to the final acknowledgement on WhatsApp, the process is structured so nothing depends on memory, luck or a due-date-evening scramble.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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 Korukkupet always know exactly what the engagement costs them.
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.
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.
Businesses with registrations in more than one State, or multiple branches under one PAN, face cross-charge, stock transfer and input service distribution questions that single-GSTIN firms never see. We keep all your registrations consistent with each other, not just compliant individually.
You deal with one accountable person who knows your business, your turnover pattern and your filing history. No repeating your story to a new voice every month, and no file falling between two desks when a deadline is approaching.
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.
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.
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.
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.
Amounts deducted by government buyers as GST TDS and by marketplaces as TCS are accepted on the portal each period, so money withheld against your GSTIN actually reaches your cash ledger instead of lying unclaimed.
Where a genuine error is found in a past period, voluntary payment through DRC-03 before any notice issues closes the matter at minimal cost, instead of letting it ripen into a demand with penalty.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| Keeping up with changes | Rate changes, portal updates and new thresholds such as the Rs.5 crore e-invoice limit are tracked by us and applied to your case proactively. | Changes are discovered after the fact — often through a rejected filing, a blocked e-way bill or a departmental letter. |
| 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. |
Kannan Street is a main connecting road in Korukkupet, about 500 m south of the centre of Korukkupet. The same consultant covers the streets immediately around it — Jawamul Sowcar Street (about 100 m); Ekambaram Street (about 300 m); 6th Street (about 300 m); Chigirintha Palayam 1st Street (about 300 m) — so a site visit on Kannan Street can usually be combined with other work in Korukkupet on the same trip. For GST purposes an address on Kannan Street falls under the Chennai North CGST Commissionerate, and the Korukkupet pincode is 600021.

GSTN Advisory dated 25 April 2025 — Phase-III of HSN reporting in Table 12 of GSTR-1/1A · 2025-04-25
GSTN implemented Phase-III of mandatory HSN reporting in Table 12 of GSTR-1 and GSTR-1A from the May 2025 return period, after the change was deferred from earlier periods. Manual keying of HSN codes is replaced by selection from a dropdown, Table 12 is split into separate B2B and B2C tabs, and new value validations compare the taxable values reported across tables. Table 13, the summary of documents issued, also became mandatory. Taxpayers up to Rs 5 crore turnover report 4-digit codes; larger taxpayers report 6-digit codes.
Practical effect: Update your billing software's HSN masters so every item carries a valid 4 or 6 digit code that matches the portal dropdown.
Goodwill Industrial Canteen - AAR Tamil Nadu, Order No. TN/09/AAR/2018, dated 30 August 2018 · 2018-08-30
The applicant prepared food and served it in the canteens of client companies at their premises. It sought the rate applicable to this arrangement. The Authority held that the supply of food and beverages on the premises of an industrial undertaking was taxable at 18 percent up to 26 July 2018 and at 5 percent from 27 July 2018, when the restaurant service entry was amended to cover canteens at offices and factories, the concessional rate being available without input tax credit.
What to do about it: Chennai canteen contractors should bill factory and office canteens at 5 percent and forgo input tax credit on their purchases.
M. Trade Links v. Union of India — Kerala High Court, judgment dated 5 July 2024, reported at 2024 KLT OnLine 1624 · 2024-07-05
A large batch of petitions challenged the constitutional validity of Section 16(4), which bars input tax credit claimed after the prescribed deadline, and of Section 16(2)(c). The High Court upheld both provisions, holding that input tax credit is a statutory concession subject to conditions and time limits fixed by the legislature. Limited relief was given for the initial years of GST having regard to the transitional difficulties and the subsequent amendments extending the deadline.
Practical effect: Do not rely on litigation to rescue late credit claims — reconcile and claim within the statutory deadline for each financial year.
