One WhatsApp message is how most of our client relationships began. Send yours today and have GSTR-1 & GSTR-3B Monthly Filing in Porur handled end to end from Rs.749 — fee confirmed in writing first, documents straight from your phone, acknowledgement the day we file.
We serve businesses on and around Mugalivakkam 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.
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. From a first registration to the annual return, the full range of GSTR-1 & GSTR-3B Monthly Filing is available to Porur businesses without stepping far from the shop or office — documents travel over WhatsApp, and our Chennai premises are open to anyone who prefers a face-to-face discussion. We serve Valasaravakkam and Ramapuram on the same footing, applying one rule everywhere: reconcile before filing, file before the due date, and keep the client informed at every stage.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
GST is confusing enough without a language barrier. Our team explains notices, tax positions and filing requirements in plain Tamil or English, whichever you and your staff in Porur are comfortable with, and keeps written communication simple and jargon-free.
The annual return and, where turnover crosses Rs.5 crore, the self-certified reconciliation statement in GSTR-9C are prepared by the same team that filed your monthly returns. Nothing about your year has to be rediscovered or explained to a stranger in December.
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.
We tell you when the composition scheme stops making sense, when QRMP suits your cash flow, and when a supplier's non-compliance is quietly costing you credit. Filing is the minimum; helping you make better GST decisions is the actual job.
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 Porur never writes back to you as a demand years later.
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.
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.
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.
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.
The hours you or your accountant spent wrestling with the portal, JSON errors and reconciliations every month return to sales, operations and customers, while trained hands manage the compliance in the background.
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.
Interest on delayed GST payment runs at 18 percent per annum, which is costlier than most working capital finance. Timely computation and payment through our calendar keeps that meter permanently at zero.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| Due-date tracking | A maintained compliance calendar with internal cut-offs days before the 11th and the 20th; we chase you for data, not the other way around. | Deadlines remembered from memory or phone alarms; one busy week and the return slips past the due date. |
| 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. |
Mugalivakkam Main Road is a main connecting road in Porur, about 1.9 km south of the centre of Porur. The same consultant covers the streets immediately around it — 11th Street (about 1.3 km); Porur Bridge (about 1.3 km); Mount Poonamallee Highway (about 1.5 km); 2nd Crosss Street (about 1.6 km) — so a site visit on Mugalivakkam Main Road can usually be combined with other work in Porur on the same trip. For GST purposes an address on Mugalivakkam 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.

GSTN Advisory — negative values in Table 3.1 of GSTR-3B, January 2025 · 2025-01
GSTN enabled reporting of negative values in Table 3.1 of GSTR-3B from the January 2025 period onwards. Where credit notes issued in a month exceed outward supplies, the net negative figure now auto-populates instead of being forced to zero. The resulting negative liability is carried in the taxpayer's records and automatically adjusted against the liability of subsequent tax periods, removing a long-standing distortion for businesses with heavy sales returns.
How we apply it: Businesses with seasonal returns or large credit notes no longer need workarounds; let the negative figure flow and track its set-off next month.
23rd GST Council Meeting, Guwahati — 10 November 2017 (PIB Release ID 1509013) · 2017-11-10
The Council decided that all taxpayers would file GSTR-3B with payment of tax by the 20th of the succeeding month until March 2018, and that for GSTR-1 taxpayers would be divided by turnover. Those with annual aggregate turnover up to Rs 1.5 crore would file GSTR-1 quarterly, and those above that figure monthly, with a detailed table of due dates. Filing of GSTR-1 was to continue without requiring GSTR-2 and GSTR-3 for the previous period.
How we apply it: The turnover-based split between monthly and quarterly GSTR-1 that still determines a Chennai business's filing calendar was created here.
Notification No. 9/2025-Central Tax (Rate) · 2025-09-17
Implementing the 56th GST Council's rate restructuring, this notification superseded Notification 1/2017-Central Tax (Rate) and prescribed the new goods rate schedule effective 22 September 2025. The 12 and 28 per cent slabs were largely abolished: most daily-use and 12 per cent goods moved to 5 per cent, most 28 per cent goods including consumer durables moved to 18 per cent, and a 40 per cent rate was reserved for a narrow list of sin and luxury goods, with compensation cess subsumed.
How we apply it: Reprice products, update billing software rate masters and review transition stock credits from 22 September 2025, since almost every trader's rate schedule changed under GST 2.0.
