Share your number — a senior GST consultant calls you back within 30 minutes.
GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Medavakkam's junction links Velachery, Tambaram, Sholinganallur and Mambakkam, making it one of south Chennai's fastest-selling apartment markets, ringed by builders, hardware and sanitaryware dealers, supermarkets and tuition centres along Medavakkam Main Road and the Sholinganallur route. Promoters using the 1 and 5 per cent residential rates must source at least 80 per cent of inputs from registered suppliers or pay tax on the shortfall under reverse charge. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Medavakkam follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Pallikaranai and Madipakkam run on the same process, entirely over WhatsApp if they prefer.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Most GST notices trace back to mismatches between GSTR-1, GSTR-3B and GSTR-2B. We reconcile these before filing, not after a notice arrives, so your returns are internally consistent and the most common triggers for ASMT-10 scrutiny simply never appear.
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.
GSTR-1 by the 11th, GSTR-3B by the 20th, CMP-08 by the 18th after each quarter — we maintain a compliance calendar for every client and start chasing your data well before the due date, so late fees never enter the picture.
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.
Freight paid to transporters, advocate fees, imported services and other notified supplies attract GST under reverse charge, with self-invoicing where the supplier is unregistered. We maintain a running RCM check every period, because this is the liability self-filers most consistently miss.
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.
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.
Late-fee waivers and amnesty windows notified by the GST Council are applied to your history within their deadlines, capturing reliefs that most businesses only hear about once the window has already closed.
Complete RFD-01 applications with proper statements and annexures move through the system faster and attract fewer deficiency memos, which means export and inverted-duty refunds reach your bank account sooner.
We spot suppliers who stop uploading invoices or filing returns and alert you before their default becomes your blocked credit, letting you recover amounts or switch vendors while the exposure is still small.
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.
Amounts deducted by government buyers as GST TDS and by marketplaces as TCS are accepted on the portal each period, so money withheld against your GSTIN actually reaches your cash ledger instead of lying unclaimed.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| Risk of notices | GSTR-1, GSTR-3B and GSTR-2B reconciled before filing, removing the mismatches that trigger most scrutiny notices. | Inconsistent figures across returns quietly build a mismatch history that surfaces later as ASMT-10 scrutiny or a demand notice. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Bell Nagar 1st Main road is a residential street in Medavakkam, about 900 m west of the centre of Medavakkam. The same consultant covers the streets immediately around it — Bell Nagar 2nd Main road (about 100 m); Medavakkam Koot Road (about 150 m); Bell Nagar 3rd Main road (about 250 m); Bharath Street (about 600 m) — so a site visit on Bell Nagar 1st Main road can usually be combined with other work in Medavakkam on the same trip. For GST purposes an address on Bell Nagar 1st Main road falls under the Chennai South CGST Commissionerate, and the Medavakkam pincode is 600100.

WABCO India Ltd - AAR Tamil Nadu, Order No. TN/10/AAR/2018, dated 27 September 2018 · 2018-09-27
The manufacturer supplied electrical wiring harness, essentially electrical wire with connectors at both ends, used in motor vehicles, and asked whether it should be classified as a motor vehicle part or as insulated electrical conductors. The Authority classified the product under heading 8544, which covers insulated wire and cable fitted with connectors, taxable at 9 percent central tax and 9 percent State tax following Notification No. 41/2017-Central Tax (Rate) dated 14 November 2017, the earlier rate having been higher.
What it means for you: Chennai auto component makers should classify by the tariff description of the article itself, not by the vehicle it eventually goes into.
Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, Schedule I entries for electrically operated vehicles and chargers · 2025-09-17
Electrically operated vehicles including two-wheelers and three-wheelers, fuel cell and hydrogen vehicles, e-bicycles and chargers or charging stations for electric vehicles remain in Schedule I at five per cent. Small petrol cars up to 1200 cc and up to 4000 mm, small diesel cars up to 1500 cc and up to 4000 mm and motorcycles up to 350 cc moved to eighteen per cent, while larger cars, hybrids above those limits and motorcycles above 350 cc were placed at forty per cent.
What it means for you: The tax gap between an electric two-wheeler at five per cent and a petrol motorcycle at eighteen per cent is now the single biggest pricing lever for Chennai vehicle dealers.
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.
Why this matters: Large Chennai taxpayers should generate the invoice reference number on the day of billing rather than leaving e-invoicing to month end.
