Our consultants provide GSTR-1 & GSTR-3B Monthly Filing to businesses across Old Washermanpet starting at Rs.749. Every file is reconciled and senior-reviewed before submission, which is why our clients see far fewer departmental queries than they did while self-filing.
We serve businesses on and around Sanjeevirayan Koil Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

GST does not distinguish between a large showroom and a small service unit — the due dates and matching systems apply equally to both. Old Washermanpet is Chennai's gold covering and jewellery manufacturing hub, with hundreds of workshops and karigar units around Sanjeevirayan Koil Street, Mint Street's northern stretch and Walltax Road feeding showrooms across Tamil Nadu. Because most pieces move between principal and job worker, maintaining job work challans and filing ITC-04 correctly, alongside making charges billing, is the neighbourhood's defining GST challenge. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Old Washermanpet follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Royapuram and Tondiarpet 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.
Your work is executed by trained GST staff working under direct senior supervision, not passed to interns learning on your file. The person preparing your return understands reverse charge, blocked credits and place of supply, because getting these wrong costs you money.
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 Old Washermanpet are never held up by a compliance gap at the gate.
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.
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 Old Washermanpet 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.
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.
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.
Your scheme choice — regular, composition or QRMP — is re-examined as turnover and margins change, so you are always paying under the structure that legitimately costs your business the least.
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.
Each period you receive a simple computation showing output tax, credit utilised and net cash payable, so GST becomes a number you understand and question rather than a figure you accept blindly.
Where a genuine error is found in a past period, voluntary payment through DRC-03 before any notice issues closes the matter at minimal cost, instead of letting it ripen into a demand with penalty.
E-commerce platforms continuously validate seller GSTINs and filing status. A consistently compliant registration keeps your listings active and settlements flowing, with no sudden suspension of your online sales channel.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Selected notifications, Council decisions and court rulings that practising consultants are applying to live cases.
Circular No. 235/29/2024-GST, dated 11 October 2024 · 2024-10-11
Implementing the 54th GST Council decisions, CBIC clarified that extruded or expanded savoury or salted products other than un-fried snack pellets fall under tariff item 1905 90 30 and attract twelve per cent prospectively, while un-fried or uncooked snack pellets continue at five per cent. Roof-mounted package unit air conditioning machines for railway coaches were held classifiable under heading 8415 and not as railway parts, and the rate position on motor car seats was settled.
Why this matters: Namkeen and extruded snack manufacturers must apply the clarified rate prospectively and can rely on the circular's regularisation for earlier supplies.
Notification No. 75/2018-Central Tax dated 31.12.2018 · 2018-12-31
This notification waived the late fee under section 47 for registered persons who failed to furnish FORM GSTR-1 for the months or quarters from July 2017 to September 2018 by the due date, provided the pending returns were furnished between 22 December 2018 and 31 March 2019. It was an amnesty aimed at bringing dormant and defaulting registrations back into the return filing system.
Why this matters: Chennai businesses that regularised early GSTR-1 defaults inside this window owe no late fee for those periods, which is useful if the department later demands one.
GSTN Advisory, November 2023 — two-factor authentication for logging into the GST portal · 2023-11
GSTN introduced two-factor authentication for the GST portal. Besides the user identity and password, a one-time password is delivered to the primary authorised signatory's registered mobile number and e-mail address, and must be entered to complete login. The measure was piloted in selected states and then extended in phases across the country, covering taxpayers as well as their sub-users. Login fails if the registered contact details on the portal are outdated and the one-time password cannot be received.
Why this matters: Keep the authorised signatory's mobile number and e-mail current on the portal, otherwise your team can be locked out on the filing due date.
