Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Whether you are a first-time registrant or an established trader, GSTR-1 & GSTR-3B Monthly Filing in Purasawalkam deserves a specialist rather than a side job. From Rs.749, our GST-focused Chennai practice runs the entire process on written checklists and senior-reviewed submissions.

GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Purasawalkam is one of Chennai's oldest shopping districts, with jewellery showrooms, silk and textile retailers and footwear chains packed along Purasawalkam High Road and Vellala Street. Wedding-season turnover is heavy and largely B2C. Traders here routinely face GSTR-1 versus GSTR-3B mismatches and input tax credit reconciliation problems with wholesale suppliers in Sowcarpet, alongside e-invoice obligations once turnover crosses Rs.5 crore. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Purasawalkam follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Kilpauk and Vepery 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.
From filing the LUT in RFD-11 at the start of each financial year to preparing RFD-01 refund claims with complete annexures, we know what makes a refund file move. Exporters and inverted-duty businesses come to us specifically for this.
If a query, ASMT-10 scrutiny notice or DRC-01 arrives on a return we filed, we stand behind our work and help you draft the reply. You are not left alone with a departmental letter and a thirty-day clock ticking against you.
Quarterly filing still demands monthly attention — IFF uploads so your buyers see their credit on time, and tax payment through PMT-06 by the 25th for the first two months of each quarter. We run that monthly rhythm so QRMP saves you effort without creating gaps.
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.
Sellers on Amazon, Flipkart and other marketplaces face a three-way match between marketplace reports, GSTR-1 and the TCS the operator deposits against your GSTIN. We reconcile all three every period and accept the TCS credit, so sellers in Purasawalkam never leave marketplace deductions unclaimed.
Composition dealers have their own rulebook — CMP-08 every quarter, GSTR-4 annually by 30 June, bills of supply instead of tax invoices, and a turnover ceiling that must be watched. We handle each of these correctly so the scheme's simplicity never turns into a violation.
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.
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.
Illness, travel or a family function no longer threatens a deadline. With a standing external process holding your calendar and data trail, filings proceed on schedule whether or not you are at your desk.
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.
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.
With returns filed ahead of the statutory due dates every period, the Rs.50-per-day GSTR-3B late fee simply stops appearing in your life, and the money stays in your business where it belongs.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| Registration and amendments | Query-resistant applications prepared correctly the first time, with supporting documents matched to what proper officers actually verify. | Repeated clarification memos and resubmissions, with weeks lost because a rent agreement or premises photograph did not meet expectations. |
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
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.
Practical effect: A Chennai printer supplying its own paper should charge 18 percent on job printed leaflets instead of assuming a lower book rate.
Notification No. 12/2025-Central Tax (Rate), dated 17 September 2025 · 2025-09-17
The old and used motor vehicle notification of January 2018 referred to Schedule IV of the 2017 rate notification to identify the vehicles it covered. Since that notification was superseded, this amendment substitutes a reference to Schedule II or Schedule III of the new goods rate notification with effect from 22 September 2025. The margin-based valuation and the bar on having availed input tax credit continue exactly as before; only the cross-reference changes.
What to do about it: Second-hand vehicle dealers need not change their computation method, but should quote the corrected notification reference in invoices and replies to officers.
M/s. Sun Dye Chem v. Assistant Commissioner (ST) — Madras High Court, W.P. No. 29676 of 2019, decided 6 October 2020 (Anita Sumanth J.) · 2020-10-06
The dealer inadvertently reported supplies under the wrong tax heads in its GSTR-1 and GSTR-3B, with the result that its customers could not claim the credit. The statutory window for amendment had closed. The Madras High Court permitted rectification of the returns for the relevant period, reasoning that the error was bona fide, the revenue suffered no loss, and the mechanism that would have allowed the taxpayer to detect the mismatch (the auto-populated matching forms) had never been made operational.
Why this matters: If a genuine head-of-tax or classification error in your GST returns has blocked your customer's credit, the Madras High Court route to rectification is available even after the ordinary time limit has passed.
