Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
GSTR-1 & GSTR-3B Monthly Filing in Korattur 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 27th 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 Korattur looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. Korattur, between the Padi flyover and Ambattur on the MTH Road corridor, mixes tier-2 auto component and fabrication units feeding Lucas TVS and the Ambattur estate with dense retail around Korattur railway station and the lake. Vendor units here must reconcile OEM debit and credit notes against GSTR-2B every month, because a single unmatched note can block input tax credit for a quarter. We serve this belt — including Padi and Ambattur — 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.
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 Korattur through each of these so month one starts correctly.
Winding up attracts its own GST obligations — the cancellation application, reversal of credit on closing stock, and the final return in GSTR-10 within three months. We close registrations properly so a business you shut in Korattur never writes back to you as a demand years later.
GSTR-3B late fees run at Rs.50 per day and interest at 18 percent per annum on unpaid tax. Our internal cut-offs sit days ahead of statutory due dates precisely so that our clients never hand the department a rupee they did not owe.
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.
Traders, manufacturers, contractors, e-commerce sellers, professionals and service exporters — we have handled GST for all of them. Whatever mix of goods and services your Korattur business supplies, the rate, classification and place-of-supply questions have almost certainly crossed our desk before.
OTP failures, DSC errors, stuck submissions on due-date evenings — we deal with the GST portal daily and know the workarounds. When the site misbehaves on the 20th, our team keeps retrying and escalating so your return still goes through.
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.
Correct, complete tax invoices signal a well-run business to customers, vendors and banks alike, quietly strengthening your credibility in every transaction where your paperwork is seen.
Whether moving between composition and regular scheme, opting into QRMP, or crossing the e-invoice threshold at Rs.5 crore, transitions are planned in advance rather than discovered after a compliance breach.
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.
Getting IGST versus CGST and SGST right at the invoice stage spares you the painful cycle of paying the correct head again and pursuing a refund of the amount paid under the wrong one.
Because monthly data is reconciled as it happens, GSTR-9 preparation before the 31 December due date becomes a review exercise rather than a painful reconstruction of twelve untidy months.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| Registration and amendments | Query-resistant applications prepared correctly the first time, with supporting documents matched to what proper officers actually verify. | Repeated clarification memos and resubmissions, with weeks lost because a rent agreement or premises photograph did not meet expectations. |
27th Street is a residential street in Korattur, about 500 m north of the centre of Korattur. The same consultant covers the streets immediately around it — Lakshmana Mudali 2nd Street (about 200 m); Dhanapal Chetty 3rd Street (about 200 m); Dhanapal Chetty 2nd Street (about 250 m); 17th Street (about 250 m) — so a site visit on 27th Street can usually be combined with other work in Korattur on the same trip. For GST purposes an address on 27th Street falls under the Chennai North CGST Commissionerate, and the Korattur pincode is 600080.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
GST law moves through notifications, circulars and court decisions. These are the ones changing how filings are prepared right now.
GSTN Advisories dated 12 April 2023 and 6 May 2023 — time limit for reporting invoices on the Invoice Registration Portal · 2023-04-12
GSTN announced that taxpayers with aggregate annual turnover of one hundred crore rupees or more would be unable to report an invoice on the Invoice Registration Portal more than seven days after the document date, with effect from 1 May 2023. After representations the implementation was deferred by three months. The idea returned later as a thirty day reporting limit applying to taxpayers with turnover of ten crore rupees and above.
What it means for you: Large Chennai taxpayers should generate the invoice reference number on the day of billing rather than leaving e-invoicing to month end.
Taghar Vasudeva Ambrish v. Appellate Authority for Advance Ruling, Karnataka, W.P. No. 14891 of 2020, Karnataka High Court, judgment dated 7 February 2022, affirmed in State of Karnataka v. Taghar Vasudeva Ambrish, Civil Appeal Nos. 7846-7847 of 2023, 2025 INSC 1380, judgment dated 4 December 2025 · 2022-02-07
Co-owners had let a residential building to a company that ran it as a hostel for students and working professionals. The advance ruling authorities denied exemption on the view that the lessee was using the property commercially. The High Court disagreed and held that leasing residential premises used as a hostel falls within Entry 13 of the IGST services exemption notification, since that entry does not require the lessee itself to occupy the premises as a residence. The Supreme Court dismissed the State's appeals on 4 December 2025 and confirmed that the end use as a residence, not the intermediate commercial layer, decides the question.
What it means for you: Chennai property owners letting buildings to hostel operators now have Supreme Court backing for periods before 18 July 2022, though later periods must also account for the registered-tenant reverse charge.
Notification No. 28/2023-Central Tax · 2023-07-31
This notification appointed 1 October 2023 as the date for most GST amendments of the Finance Act 2023. The most consequential change bars taxpayers from filing GSTR-1, GSTR-3B, GSTR-9 and GSTR-8 after three years from their due date. The GST portal began actually blocking such time-barred returns from the July 2025 tax period, permanently freezing any unfiled compliance older than three years along with the credit flowing from it.
Practical effect: Any return more than three years past its due date can no longer be filed at all, so clear historic backlogs immediately rather than assuming they can be regularised later.
