Late fees, blocked credit and mismatch notices cost far more than professional help ever will. We complete GSTR-1 & GSTR-3B Monthly Filing for Kolathur businesses from Rs.749, matching every figure against portal data before anything reaches the department.
We serve businesses on and around Jawaharlal Nehru Road (100 Feet Road) — 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.
If you operate in Kolathur, GST deadlines arrive with the same force as anywhere in Chennai — GSTR-1 by the 11th, GSTR-3B by the 20th. Kolathur is India's best-known ornamental fish hub, with breeding farms and aquarium shops clustered off Red Hills Road near Retteri junction, alongside hardware stores and construction material suppliers serving fast-growing residential pockets like Poombuhar Nagar. Many fish breeders and online sellers cross the Rs.40 lakh goods threshold without realising it, making first-time registration and e-commerce reporting the local GST pain point. We provide GSTR-1 & GSTR-3B Monthly Filing to businesses across Kolathur and the adjoining Villivakkam and Perambur localities, maintaining a compliance calendar for every client so due dates are met without last-minute panic, late fees or interest at 18 percent per annum.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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.
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.
GSTR-3B late fees run at Rs.50 per day and interest at 18 percent per annum on unpaid tax. Our internal cut-offs sit days ahead of statutory due dates precisely so that our clients never hand the department a rupee they did not owe.
We match your purchase register against GSTR-2B every period, follow up on invoices your suppliers have not uploaded, and ensure every rupee of eligible input tax credit is claimed. Clients routinely recover credit they were silently losing under self-filing.
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.
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

Practical outcomes our clients measure us by.
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.
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.
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.
Correct e-way bills matched to correct invoices mean your consignments clear roadside inspections cleanly, avoiding detention proceedings whose penalties can far exceed the tax on the goods being carried.
Systematic GSTR-2B matching and supplier follow-up mean input tax credit that was leaking away under self-filing is captured each month, directly reducing the cash you pay out with every GSTR-3B.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Jawaharlal Nehru Road (100 Feet Road) is a primary arterial road in Kolathur, about 1.7 km north of the centre of Kolathur. The same consultant covers the streets immediately around it — Grand Northern Trunk Road (about 900 m); 1st Main Road (about 1.0 km); Kolathur Road (about 1.2 km); Paper Mills Road (about 1.3 km) — so a site visit on Jawaharlal Nehru Road (100 Feet Road) can usually be combined with other work in Kolathur on the same trip. For GST purposes an address on Jawaharlal Nehru Road (100 Feet Road) falls under the Chennai North CGST Commissionerate, and the Kolathur pincode is 600099.

Navbharat Imports - AAR Tamil Nadu, Advance Ruling No. 35/AAR/2021, dated 30 September 2021 · 2021-09-30
The importer sold a range of children's toys, some containing electronic circuits and some working purely mechanically. It asked for the correct rate on each. The Authority held that toys containing electronic components attract 18 percent under the residual entry for electronic toys, irrespective of how those components are used, so children's scooters and smart tricycles with lights and music are taxed at 18 percent, while toys that work without electronics remain at 12 percent.
Why this matters: Chennai toy traders must classify item by item, because a single electronic component moves a product from 12 to 18 percent.
GSTN Advisory, November 2024 — 30-day IRP reporting limit for AATO Rs 10 crore and above · 2024-11
GSTN advised that from 1 April 2025, taxpayers with annual aggregate turnover of Rs 10 crore and above cannot report e-invoices on the Invoice Registration Portals beyond 30 days from the document date. The restriction, earlier applicable only to very large taxpayers of Rs 100 crore and above, covers invoices, credit notes and debit notes. The IRP validation simply rejects documents older than 30 days, so late reporting becomes impossible.
Why this matters: Automate same-day or same-week IRN generation, because an invoice missed beyond 30 days cannot be e-invoiced at all and endangers the buyer's ITC.
Notification No. 34/2020-Central Tax · 2020-04-03
The statement of self-assessed tax in Form GST CMP-08 for the quarter ending 31 March 2020 was allowed to be furnished up to 7 July 2020 instead of 18 April 2020. The annual return in Form GSTR-4 for the financial year 2019-20 was allowed up to 15 July 2020 instead of 30 April 2020. This was the first COVID concession specifically for composition taxpayers, who had otherwise been left out of the relief given to regular filers.
How we apply it: Chennai composition dealers such as small traders and eateries had a three-month reprieve for the 2019-20 filings, which should be cited against any late-fee entry for that year.
