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 Sundaram Naidu 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.
Businesses in Old Washermanpet looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. 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. We serve this belt — including Royapuram and Tondiarpet — with fixed fees quoted upfront, a written document checklist, and filings completed ahead of statutory due dates. Every acknowledgement is shared the day it is generated, and our support continues if the department raises any query on work we have filed.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
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.
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.
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.
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.
New branches, new product lines and interstate sales all carry GST consequences. With standing professional support, you expand knowing registrations, invoicing and returns will keep pace with the business.
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.
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.
When a business winds up, proper cancellation and a timely final return ensure the file is genuinely closed, so no demand or late-fee computation resurfaces against you long after the shutters came down.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
27th GST Council Meeting (video conference) — 4 May 2018 (PIB Release ID 1531331) · 2018-05-04
Acting on the report of the Group of Ministers on IT simplification, the Council approved the design principles for a new return: one monthly return for all taxpayers except composition dealers and a few others, with staggered due dates by turnover; unidirectional flow of invoices uploaded by the seller at any time during the month, which would be the valid document for the buyer's credit; no requirement to upload purchase invoices; four-digit HSN for B2B invoices; and automatic computation of liability and credit.
How we apply it: The upload-lock-pay idea behind today's auto-populated GSTR-2B and GSTR-3B originates in these principles.
Notification No. 9/2025-Central Tax (Rate), dated 17 September 2025, Schedules IV, V and VI · 2025-09-17
Schedule IV at 1.5 per cent central tax, that is three per cent combined, covers pearls, silver, gold, platinum, base metals clad with precious metal, articles of jewellery, goldsmiths' and silversmiths' wares, imitation jewellery and coin. Schedule V at 0.125 per cent, that is 0.25 per cent combined, covers rough or simply sawn diamonds and unworked precious and semi-precious stones. Schedule VI at 0.75 per cent, that is 1.5 per cent combined, covers cut and polished diamonds and worked synthetic stones.
Practical effect: Jewellers in Chennai continue to charge three per cent on ornaments, with the separate making charge taxed as a service, so no repricing was needed in September 2025.
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.
Why this matters: Chennai auto component makers should classify by the tariff description of the article itself, not by the vehicle it eventually goes into.
