If you operate in West Mambalam, GST deadlines arrive with the same force as anywhere in Chennai — GSTR-1 by the 11th, GSTR-3B by the 20th. West Mambalam packs caterers, flower and pooja goods sellers, tailoring units and tuition centres into dense streets like Lake View Road and Arya Gowda Road beside Mambalam railway station. Family-run businesses here often operate near the Rs.40 lakh goods and Rs.20 lakh services registration thresholds, so registration timing, composition eligibility and purchases from unregistered dealers are the common questions. We provide GSTR-1 & GSTR-3B Monthly Filing to businesses across West Mambalam and the adjoining T. Nagar and Ashok Nagar 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 work with Chennai GST ranges and circles every week, including the jurisdiction covering West Mambalam. 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.
A registration cancelled for non-filing is not the end of the road. We bring the pending returns up to date, clear the dues and file the revocation application in REG-21 within the permitted window, restoring suspended and cancelled GSTINs to active status.
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 West Mambalam never leave marketplace deductions unclaimed.
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 West Mambalam compete with each other; complete confidentiality is a condition of our work.
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.
We are a Chennai firm with a physical office, not a faceless portal. If you prefer to sit across a table with your papers, you are welcome. Clients from West Mambalam regularly visit us for registrations, notice discussions and annual return reviews.
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.

Rs.7,999/year
Practical outcomes our clients measure us by.
Interest on delayed GST payment runs at 18 percent per annum, which is costlier than most working capital finance. Timely computation and payment through our calendar keeps that meter permanently at zero.
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.
With the LUT filed at the start of each financial year and refund claims tracked to credit, exporters supply without blocking funds in IGST and recover accumulated credit on schedule.
A fixed professional fee is almost always cheaper than the combination of late fees, interest, lost credit and staff hours that informal, last-minute compliance quietly accumulates over a year.
Getting IGST versus CGST and SGST right at the invoice stage spares you the painful cycle of paying the correct head again and pursuing a refund of the amount paid under the wrong one.
We spot suppliers who stop uploading invoices or filing returns and alert you before their default becomes your blocked credit, letting you recover amounts or switch vendors while the exposure is still small.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
We track every notification, circular and judgment that changes a filing position, so your returns and replies reflect the current law.
GSTN Advisory — negative values in Table 3.1 of GSTR-3B, January 2025 · 2025-01
GSTN enabled reporting of negative values in Table 3.1 of GSTR-3B from the January 2025 period onwards. Where credit notes issued in a month exceed outward supplies, the net negative figure now auto-populates instead of being forced to zero. The resulting negative liability is carried in the taxpayer's records and automatically adjusted against the liability of subsequent tax periods, removing a long-standing distortion for businesses with heavy sales returns.
Why this matters: Businesses with seasonal returns or large credit notes no longer need workarounds; let the negative figure flow and track its set-off next month.
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.
Practical effect: 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.
Notification No. 21/2021-Central Tax (Rate), dated 31 December 2021 · 2021-12-31
On 31 December 2021, the same day as the 46th GST Council meeting convened at the instance of Tamil Nadu and other States, the Government superseded the November notification. The proposed increase on textiles was dropped, so fabrics, yarn, garments and made-ups continued at five per cent, but the footwear change survived and all footwear became taxable at twelve per cent from 1 January 2022 irrespective of price. The value threshold that had earlier kept cheap footwear at five per cent disappeared.
How we apply it: From January 2022 to September 2025 every pair of footwear attracted twelve per cent regardless of price, and rate mistakes in that window are a common scrutiny point.
