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. For businesses here, staying on the right side of GST is not optional — buyers check compliance, and the department's systems match every return. Our firm provides GSTR-1 & GSTR-3B Monthly Filing to clients across Porur and neighbouring Valasaravakkam and Ramapuram, combining Chennai jurisdiction familiarity with disciplined deadline tracking. Whether you run a shop, a service practice or a growing trading concern, we handle the portal work so you can stay focused on the business itself.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Your cash ledger, credit ledger and liability register are reviewed regularly, not just at filing time. Excess balances are flagged for use or refund, and where a genuine slip surfaces, a voluntary payment through DRC-03 settles it before it can mature into a notice.
No filing leaves our desk on a junior's judgement alone. A senior GST practitioner reviews your figures, ITC claims and tax computation before submission, so errors are caught at our table and not by the department months later through a notice.
In the days before the 11th and the 20th, our team runs extended hours and a strict internal queue, so a client who sends data late in the window is still filed on time. Peak-season crush at our end never becomes a late fee at yours.
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 Porur through each of these so month one starts correctly.
We are a Chennai firm with a physical office, not a faceless portal. If you prefer to sit across a table with your papers, you are welcome. Clients from Porur regularly visit us for registrations, notice discussions and annual return reviews.
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.
Timeline: Filed before the 11th and 20th of every month · No hidden charges · GST invoice provided

Practical outcomes our clients measure us by.
Statutory windows such as thirty days for an ASMT-11 reply are tracked from the day a notice arrives, so responses go in on time, complete, and with your best case properly presented.
You know your expected GST outflow days before the 20th, not on the night of filing. That advance visibility lets you plan payments, collections and bank balances instead of scrambling for funds at the deadline.
Rates, reverse charge, place of supply and blocked credits are applied correctly at the preparation stage, so you neither overpay tax you do not owe nor underpay and invite demands with penalty later.
Advances received for services attract GST on receipt while advances for goods generally do not; applying this distinction correctly means you neither prepay tax unnecessarily nor omit a liability that surfaces later with interest.
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.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Chettiyaragaram Main Road is a main connecting road in Porur, about 1.3 km north-west of the centre of Porur. The same consultant covers the streets immediately around it — Samayapuram Nagar Main Road (about 750 m); Porur Bridge (about 1.3 km); 2nd Crosss Street (about 1.4 km); 1st Cross Street (about 1.4 km) — so a site visit on Chettiyaragaram Main Road can usually be combined with other work in Porur on the same trip. For GST purposes an address on Chettiyaragaram 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.
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
34th GST Council Meeting (video conferencing) — 19 March 2019 · 2019-03-19
The Council gave promoters a one-time option to continue paying tax at the old effective rates of eight or twelve per cent with input tax credit on ongoing projects, meaning buildings where both construction and actual booking had started before 1 April 2019 and which were not completed by 31 March 2019. The option had to be exercised once within a prescribed time frame, failing which the new rates applied automatically. Credit for projects moving across was to be transitioned pro rata.
Why this matters: Chennai builders who did not formally exercise the option in 2019 are on the one and five per cent no-credit rates, and any credit claimed since then is exposed to reversal.
Circular No. 247/04/2025-GST · 2025-02-14
Following the 55th GST Council meeting, CBIC clarified disputed classifications: ready-to-eat salted popcorn is taxable at 5 per cent (12 per cent if pre-packaged and labelled) while caramelised popcorn falls at 18 per cent as sugar confectionery; autoclaved aerated concrete blocks with over 50 per cent fly ash content attract 12 per cent; and dried pepper supplied by an agriculturist remains exempt. Past periods were regularised on an as-is-where-is basis to prevent retrospective demands.
How we apply it: Food processors and building-material traders should re-check product classifications against this circular, since regularisation protects past periods but the clarified rates bind future supplies.
GSTN Advisory, November 2023 — two-factor authentication for logging into the GST portal · 2023-11
GSTN introduced two-factor authentication for the GST portal. Besides the user identity and password, a one-time password is delivered to the primary authorised signatory's registered mobile number and e-mail address, and must be entered to complete login. The measure was piloted in selected states and then extended in phases across the country, covering taxpayers as well as their sub-users. Login fails if the registered contact details on the portal are outdated and the one-time password cannot be received.
What to do about it: Keep the authorised signatory's mobile number and e-mail current on the portal, otherwise your team can be locked out on the filing due date.
