Finding dependable GSTR-1 & GSTR-3B Monthly Filing in Thiruverkadu usually means choosing between a distant online portal and an overloaded local accountant. Thiruverkadu draws steady pilgrim crowds to the Devi Karumariamman temple, supporting flower and pooja shops on Sannathi Street, eateries, marriage halls and a fast-growing residential belt along Koladi Road and Thiruverkadu Main Road towards Velappanchavadi on Poonamallee High Road. Marriage hall owners charging 18 per cent GST on hall rent and caterers billing event food are the compliance profiles this town produces most. We offer a third option: a professional Chennai GST practice that treats Thiruverkadu, Avadi and Maduravoyal as home ground, responds the same working day, files ahead of deadlines, and stands behind its work if a notice ever arrives on a return we prepared.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
When an ADT-01 audit intimation or a personal hearing date arrives, we compile the records, prepare the reconciliations and draft the submissions, and coordinate closely with your authorised representative. You walk into the proceeding prepared, not improvising in front of an officer.
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.
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.
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 Thiruverkadu business supplies, the rate, classification and place-of-supply questions have almost certainly crossed our desk before.
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.
If your GSTR-1 and GSTR-3B start drifting apart, if a large supplier stops filing, or if your turnover approaches the e-invoice threshold, we flag it to you immediately. Early warnings from our side are cheaper than departmental letters later.
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
Rs.7,999/year
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.
Systematic GSTR-2B matching and supplier follow-up mean input tax credit that was leaking away under self-filing is captured each month, directly reducing the cash you pay out with every GSTR-3B.
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.
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.
Your billing staff are guided on invoice fields, rates and series discipline, so mistakes are prevented where they originate — at the counter — instead of being repaired later in the returns.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Perumal Koil Street is a main connecting road in Thiruverkadu, about 1.0 km south-east of the centre of Thiruverkadu. The same consultant covers the streets immediately around it — Thiruverkadu - Ambattur Road (about 950 m); 4th Street (about 1.2 km); 4th Cross Road (about 1.3 km); Sundaracholavaram Main Road (about 1.3 km) — so a site visit on Perumal Koil Street can usually be combined with other work in Thiruverkadu on the same trip. For GST purposes an address on Perumal Koil Street falls under the Chennai Outer CGST Commissionerate, and the Thiruverkadu pincode is 600077.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
Positions we rely on when preparing filings and drafting replies — with the exact citation, so you can verify each one.
GSTN Advisory dated 7 June 2025 — non-editable auto-populated liability in GSTR-3B · 2025-06-07
After an October 2024 advisory and a January 2025 deferment, GSTN confirmed that from the July 2025 tax period the auto-populated outward tax liability in GSTR-3B, drawn from GSTR-1, IFF or GSTR-1A, is hard-locked and cannot be edited manually while filing. Any correction to sales figures must be made through GSTR-1A before GSTR-3B is filed. The change is intended to end mismatches between GSTR-1 and GSTR-3B.
What to do about it: Reconcile sales data before filing GSTR-1 each month, since GSTR-3B can no longer be adjusted at the last minute.
Commissioner of Customs and Central Excise v. Hongo India (P) Ltd — Supreme Court, (2009) 5 SCC 791, judgment dated 27-03-2009 · 2009-03-27
The Supreme Court held that where a special taxing statute provides a complete code with its own limitation scheme, the general provisions of the Limitation Act permitting condonation of delay do not apply. Delay in filing a reference or appeal beyond the period prescribed by the special statute cannot be condoned. The scheme, language and object of the special Act determine whether the Limitation Act is impliedly excluded.
What it means for you: Chennai businesses must treat GST appeal and revision deadlines as absolute, since general limitation relief is not available.
Notification No. 04/2017-Central Tax dated 19.06.2017 · 2017-06-19
This notification designated www.gst.gov.in, managed by the Goods and Services Tax Network, as the Common Goods and Services Tax Electronic Portal for registration, payment of tax, and furnishing of returns. It gives legal status to the portal, which matters because the CGST Act and Rules repeatedly require documents to be filed electronically on the common portal rather than in paper form with a jurisdictional office.
Why this matters: Filings made anywhere other than the notified portal have no legal effect, so a Chennai business cannot discharge a return obligation by emailing or hand-delivering a return to the department.
References are provided for general information. Verify the current position on gst.gov.in or cbic.gov.in before acting.
Straight answers from practising GST consultants — based on the CGST Act, current CBIC notifications and day-to-day portal experience.
