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 Koyambedu 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.
We serve businesses on and around 1st Main Road — 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. Koyambedu hosts one of Asia's largest perishables markets, the Koyambedu Wholesale Market Complex, and the CMBT bus terminus, driving trade by vegetable and fruit wholesalers, flower merchants, commission agents and transporters. Fresh produce is largely exempt while packaged and labelled goods are taxable, so mixed supplies, commission income, GTA reverse charge and e-way bills for outstation consignments dominate compliance here. That is why our GSTR-1 & GSTR-3B Monthly Filing engagements in Koyambedu follow the same discipline whatever the client's size: written checklists, reconciliation before filing and every acknowledgement archived. Businesses from Arumbakkam and Anna Nagar 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.
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.
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.
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.
Your sales figures, supplier lists and login credentials are handled only by our engaged team, stored securely and never shared with any third party. Many of our clients in Koyambedu compete with each other; complete confidentiality is a condition of our work.
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.
GST is confusing enough without a language barrier. Our team explains notices, tax positions and filing requirements in plain Tamil or English, whichever you and your staff in Koyambedu are comfortable with, and keeps written communication simple and jargon-free.
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.
Timeline: Filed before the 11th and 20th of every month · No hidden charges · GST invoice provided
Rs.7,999/year
Practical outcomes our clients measure us by.
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.
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.
Whether moving between composition and regular scheme, opting into QRMP, or crossing the e-invoice threshold at Rs.5 crore, transitions are planned in advance rather than discovered after a compliance breach.
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.
You know your expected GST outflow days before the 20th, not on the night of filing. That advance visibility lets you plan payments, collections and bank balances instead of scrambling for funds at the deadline.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
1st Main Road is a residential street in Koyambedu, about 750 m south of the centre of Koyambedu. The same consultant covers the streets immediately around it — Ayyappa Nagar Main Road (about 150 m); 2nd Main Road (about 200 m); Magilampoo Street (about 200 m); Vallavan Nagar Main Road (about 250 m) — so a site visit on 1st Main Road can usually be combined with other work in Koyambedu on the same trip. For GST purposes an address on 1st Main Road falls under the Chennai North CGST Commissionerate, and the Koyambedu pincode is 600107.

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.
How we apply it: A Chennai printer supplying its own paper should charge 18 percent on job printed leaflets instead of assuming a lower book rate.
Circular No. 206/18/2023-GST · 2023-10-31
The Board answered a set of service taxability questions arising from the 52nd GST Council meeting. Among them, it confirmed that District Mineral Foundation Trusts set up by State Governments qualify as Governmental Authorities and are therefore eligible for the exemptions available to such authorities. Other classification and exemption questions on specified services were also settled, so that field formations across States adopt a uniform view rather than issuing conflicting demands.
What it means for you: Contractors in Tamil Nadu working for statutory trusts and authorities should verify the exemption position against this circular before quoting a GST-inclusive price.
M/s. Refex Industries Ltd v. Assistant Commissioner of CGST & Central Excise — Madras High Court, W.P. Nos. 23360 & 23361 of 2019, decided 6 January 2020 (Anita Sumanth J.) · 2020-01-06
The department demanded interest on the entire tax shown in belated GSTR-3B returns, including the part discharged from input tax credit. The Madras High Court held that interest under Section 50 is compensatory, and can be levied only on the belated cash payment of tax, not on input tax credit that was lying with the department all along. The proviso inserted in Section 50(1) was treated as curative and applicable to earlier periods as well.
What to do about it: A Chennai business that filed GSTR-3B late should verify that any interest demand is computed only on the cash component of the tax, and contest interest charged on the ITC-set-off portion.
