Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Late fees, blocked credit and mismatch notices cost far more than professional help ever will. We complete GSTR-1 & GSTR-3B Monthly Filing for Chromepet businesses from Rs.749, matching every figure against portal data before anything reaches the department.
We serve businesses on and around Nehru Nagar — 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.
Chromepet grew around the old Chrome Leather Company and now centres on the MIT campus, hospitals, private hostels and dense retail along GST Road and Radha Nagar. Hostels and coaching centres frequently misjudge GST applicability on accommodation and fees, and GST Road retailers see recurring GSTR-1 versus GSTR-3B turnover mismatches that invite ASMT-10 notices requiring an ASMT-11 reply within 30 days. When businesses of this kind evaluate GSTR-1 & GSTR-3B Monthly Filing, the real question is not price alone but who answers when something goes wrong. We serve Chromepet, Pallavaram and Tambaram on a standing commitment: responses within the same working day, senior scrutiny before every submission, and continued support if the department ever writes back on work carrying our preparation.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Winding up attracts its own GST obligations — the cancellation application, reversal of credit on closing stock, and the final return in GSTR-10 within three months. We close registrations properly so a business you shut in Chromepet never writes back to you as a demand years later.
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.
GSTR-1 requires four-digit HSN reporting for turnover up to Rs.5 crore and six digits above it, and a wrong code often means a wrong rate. We verify the classification of what you actually supply, so your invoices and returns rest on defensible codes.
We work with Chennai GST ranges and circles every week, including the jurisdiction covering Chromepet. We know how local proper officers examine registrations, what supporting documents they routinely call for, and how to present a file so it moves without repeated queries.
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.
You receive a WhatsApp message when documents are received, when the draft is ready for your approval, and when the return or application is filed, along with the acknowledgement. You never have to call and ask what is happening with your file.
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.
The 11th and the 20th stop being days of dread. You approve a prepared draft, we file, and the acknowledgement lands on your WhatsApp — month after month, without drama.
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.
Because monthly data is reconciled as it happens, GSTR-9 preparation before the 31 December due date becomes a review exercise rather than a painful reconstruction of twelve untidy months.
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.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
Real notifications, rulings and case law our consultants track — and apply to client filings and notice replies.
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.
How we apply it: 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.
9th GST Council Meeting, New Delhi — 16 January 2017 (Signed Minutes, Agenda Item 5) · 2017-01-16
With the revised model law still to be brought back to the Council, the fitment of rates incomplete and taxpayers needing time to configure their accounting systems, the Council unanimously agreed to extend the GST rollout date to 1 July 2017. Maharashtra, Assam and Bihar had pressed for 1 April 2017, Assam adding that changing the tax regime in the middle of a financial year was undesirable, but the Chairperson observed that the legal and rate work would spill into March 2017 and that an April deadline had become a major challenge. Tamil Nadu and Karnataka supported 1 July 2017 as the more practical date.
What it means for you: GST law in India runs from 1 July 2017, so the first return periods, the first annual return and all transitional credit deadlines are measured from that date.
Circular No. 179/11/2022-GST · 2022-08-03
The Board settled several goods classification disputes following the 47th GST Council meeting. It confirmed that electrically operated vehicles attract the five per cent rate whether or not they are fitted with a battery pack at the time of supply, and that treated sewage water is exempt because the exclusion for purified water does not extend to it. Rates on fly ash bricks and blocks and on certain by-products of milling of pulses were also clarified.
How we apply it: Chennai dealers in electric vehicles and construction materials should check their invoicing against this circular, since past classification errors are a common audit finding.
