We serve businesses on and around Samayapuram Nagar Main Road — 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.
Choosing GSTR-1 & GSTR-3B Monthly Filing in Porur is ultimately an act of trust: you are handing over sales figures, purchase records and portal access. Porur commands the junction of Mount Poonamallee Road and Arcot Road, the gateway to Chennai's western IT corridor, with the Sri Ramachandra medical campus, IT offices, construction firms and logistics yards nearby. IT and ITES exporters need LUT filings under RFD-11 each financial year and refunds through RFD-01, while contractors face Section 17(5) credit blocks and site-to-site e-way bills. 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 Porur, Valasaravakkam and Ramapuram 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.
Every acknowledgement, challan, computation sheet and filed return is saved and shared with you in an organised folder. When a bank, buyer or GST officer asks for a document from two years ago, it reaches you the same day without any scrambling.
Goods sent to job workers must move on delivery challans, return within the statutory period, and be reported in ITC-04. We track every outward and return leg for manufacturing clients in Porur, so inputs sent out for processing never quietly convert into a deemed supply carrying tax and interest.
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.
Your sales figures, supplier lists and login credentials are handled only by our engaged team, stored securely and never shared with any third party. Many of our clients in Porur compete with each other; complete confidentiality is a condition of our work.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Porur. We know how local proper officers examine registrations, what supporting documents they routinely call for, and how to present a file so it moves without repeated queries.
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.
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.

Rs.7,999/year
Practical outcomes our clients measure us by.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
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.
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.
Illness, travel or a family function no longer threatens a deadline. With a standing external process holding your calendar and data trail, filings proceed on schedule whether or not you are at your desk.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Samayapuram Nagar Main Road is a main connecting road in Porur, about 650 m north-west of the centre of Porur. The same consultant covers the streets immediately around it — 2nd Crosss Street (about 700 m); 1st Cross Street (about 700 m); Porur Bridge (about 700 m); Chettiyaragaram Main Road (about 750 m) — so a site visit on Samayapuram Nagar Main Road can usually be combined with other work in Porur on the same trip. For GST purposes an address on Samayapuram Nagar Main Road falls under the Chennai South CGST Commissionerate, and the Porur pincode is 600116.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
Real notifications, rulings and case law our consultants track — and apply to client filings and notice replies.
Notification No. 12/2017-Central Tax dated 28.06.2017 · 2017-06-28
This notification prescribed the number of digits of the Harmonised System of Nomenclature code to be shown on a tax invoice, keyed to the turnover in the preceding financial year. Businesses up to Rs 1.5 crore were not required to show any HSN code, those between Rs 1.5 crore and Rs 5 crore had to show two digits, and those above Rs 5 crore had to show four digits. The requirements were tightened in later years.
How we apply it: This is the historical benchmark for testing whether an old Chennai invoice was defective, and it explains why HSN reporting obligations have progressively become stricter.
GSTN Advisory, September 2022 — changes in Table 4 of Form GSTR-3B pursuant to Notification No. 14/2022-Central Tax, dated 5 July 2022 and Circular No. 170/02/2022-GST, dated 6 July 2022 · 2022-09
From the August 2022 return period the whole of the credit appearing in GSTR-2B must first be reported as credit available in Table 4(A), with ineligible and reversible credit then shown separately in Table 4(B). Reversals that can be reclaimed later, such as those under Rule 37, go into Table 4(B)(2) and the reclaim is reported in Table 4(D)(1). Only the net figure reaches the electronic credit ledger.
How we apply it: Report gross credit and reversals separately in Table 4, because the department now compares your ledger with GSTR-2B line by line.
Coronation Arts Crafts - AAR Tamil Nadu, Advance Ruling No. 19/ARA/2022, dated 31 May 2022 · 2022-05-31
A printing house printed leaflets and similar material using content supplied by the customer but paper, ink and other physical inputs of its own. It asked for the correct classification and rate. The Authority held that this is a composite supply in which the printing service is the principal supply, and the supply is therefore taxable at 18 percent. The customer supplying only the content or artwork did not alter the classification.
Why this matters: A Chennai printer supplying its own paper should charge 18 percent on job printed leaflets instead of assuming a lower book rate.
