Most of it happens without you leaving your shop counter. Share your documents on WhatsApp, approve the prepared draft, and your GSTR-1 & GSTR-3B Monthly Filing is completed on the portal from Rs.749 — by a Chennai team that businesses across Madipakkam have relied on for years.
We serve businesses on and around 13th extension Street — 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.
Madipakkam's apartment construction boom drives its commerce: builders, hardware and building-material dealers, supermarkets and pharmacies along Madipakkam Main Road and Medavakkam Main Road. Builders selling under-construction flats apply concessional GST rates without input tax credit, while material dealers moving consignments above Rs.50,000 need e-way bills even for short local deliveries to sites. When businesses of this kind evaluate GSTR-1 & GSTR-3B Monthly Filing, the real question is not price alone but who answers when something goes wrong. We serve Madipakkam, Velachery and Nanganallur on a standing commitment: responses within the same working day, senior scrutiny before every submission, and continued support if the department ever writes back on work carrying our preparation.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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 Madipakkam regularly visit us for registrations, notice discussions and annual return reviews.
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.
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.
E-invoicing is mandatory once turnover crosses Rs.5 crore and e-way bills apply to goods movements above Rs.50,000. We set up, train and troubleshoot both systems, so your despatches from Madipakkam are never held up by a compliance gap at the gate.
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.
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 Madipakkam, so inputs sent out for processing never quietly convert into a deemed supply carrying tax and interest.
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.
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.
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.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
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.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
13th extension Street is a residential street in Madipakkam, about 1.3 km south-east of the centre of Madipakkam. The same consultant covers the streets immediately around it — 14th Street extension (about 300 m); 15th Street (about 350 m); 11th Street (about 400 m); 10th Street (about 400 m) — so a site visit on 13th extension Street can usually be combined with other work in Madipakkam on the same trip. For GST purposes an address on 13th extension Street falls under the Chennai South CGST Commissionerate, and the Madipakkam pincode is 600091.

Notification No. 1/2017-Central Tax (Rate), dated 28 June 2017 (G.S.R. 673(E)) · 2017-06-28
This was the founding rate notification for goods. It listed every taxable item against its Customs Tariff heading in six schedules, prescribing central tax of 2.5, 6, 9, 14, 1.5 and 0.125 per cent, which with the matching State tax gave the familiar 5, 12, 18, 28, 3 and 0.25 per cent rates. Anything not listed in a schedule or exempted separately fell to the residual 18 per cent rate. It was amended dozens of times before being superseded on 22 September 2025.
Why this matters: For any dispute about a supply made up to 21 September 2025, the rate must be traced to the schedule entry of this notification as it stood on the date of supply, not to today's rate.
Commissioner of Central Excise, Bolpur v. Ratan Melting and Wire Industries — Supreme Court, Constitution Bench, (2008) 13 SCC 1, judgment dated 14-10-2008 · 2008-10-14
A five-judge Bench held that circulars issued by the Board cannot prevail over the statute, and are not binding on courts. Where the Supreme Court or a High Court has declared the law on an issue, that declaration prevails and any contrary circular ceases to have effect. Circulars remain an aid to administration and can bind officers, but they cannot enlarge or restrict what the legislature has enacted.
Practical effect: Chennai businesses should treat CBIC circulars as useful administrative guidance, but should not rely on one that conflicts with the plain words of the GST Act.
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.
