The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Nungambakkam permanently ahead of both, delivering GSTR-1 & GSTR-3B Monthly Filing from Rs.749 with reconciliation, senior review and WhatsApp acknowledgements as standard.
We serve businesses on and around Ponnangipuram — 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.
Nungambakkam is prime corporate Chennai: banks, consulting firms and company headquarters on Nungambakkam High Road and Sterling Road, with luxury retail on Khader Nawaz Khan Road. Service exporters and consultancies dominate, so LUT renewals under RFD-11 each financial year, place-of-supply determinations on cross-border services and input tax credit on high-value office rentals are the recurring GST questions in this market. We have supported businesses of exactly this profile with GSTR-1 & GSTR-3B Monthly Filing across Nungambakkam for years, along with clients from Chetpet and T. Nagar. The engagement is simple: one point of contact, a clear fee, documents over WhatsApp or in person at our Chennai office, and senior review before anything is submitted on the portal. What you get in return is clean filings, archived records and far fewer reasons for the department to write to you.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Your cash ledger, credit ledger and liability register are reviewed regularly, not just at filing time. Excess balances are flagged for use or refund, and where a genuine slip surfaces, a voluntary payment through DRC-03 settles it before it can mature into a notice.
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.
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.
You deal with one accountable person who knows your business, your turnover pattern and your filing history. No repeating your story to a new voice every month, and no file falling between two desks when a deadline is approaching.
You are told the full fee before we begin, in writing. No surprise additions for uploads, revisions or acknowledgements. Government fees and taxes, where applicable, are shown separately, so businesses in Nungambakkam always know exactly what the engagement costs them.
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.
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.
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.
Filed returns, challans, reconciliations and working papers are archived in order from day one. If an audit or departmental verification comes, your file is ready the same week, not assembled in a panic.
Sales returns, discounts and price revisions are adjusted through properly reported credit notes within the statutory window, so you never keep paying tax on turnover you have already reversed.
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.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |

GSTN Advisory dated 25 April 2025 — Phase-III of HSN reporting in Table 12 of GSTR-1/1A · 2025-04-25
GSTN implemented Phase-III of mandatory HSN reporting in Table 12 of GSTR-1 and GSTR-1A from the May 2025 return period, after the change was deferred from earlier periods. Manual keying of HSN codes is replaced by selection from a dropdown, Table 12 is split into separate B2B and B2C tabs, and new value validations compare the taxable values reported across tables. Table 13, the summary of documents issued, also became mandatory. Taxpayers up to Rs 5 crore turnover report 4-digit codes; larger taxpayers report 6-digit codes.
How we apply it: Update your billing software's HSN masters so every item carries a valid 4 or 6 digit code that matches the portal dropdown.
28th GST Council Meeting, New Delhi — 21 July 2018 (PIB Release ID 1539570) · 2018-07-21
Finalising the formats behind the principles approved in May, the Council approved optional quarterly return filing with monthly payment of tax for small taxpayers with turnover below Rs 5 crore, noting that 93 per cent of taxpayers fall below that figure. Two simplified formats were designed: Sahaj for small traders making only B2C supplies and Sugam for those making both B2B and B2C supplies. Both required less information than the regular return.
What it means for you: Sahaj and Sugam were never implemented as designed, but the Rs 5 crore turnover line and the quarterly-return-with-monthly-payment model survive in today's QRMP scheme.
Krishna Bhavan Foods and Sweets - AAR Tamil Nadu, Order No. TN/24/AAR/2021, dated 18 June 2021, upheld by AAAR Tamil Nadu, Order No. TN/AAAR/02/2022, dated 13 January 2022 · 2021-06-18
The applicant sold packaged ready to cook instant mixes for dosai, idli, tiffin items, sweets, health mix and porridge. It argued that these were only flours of cereals and pulses taxable at 5 percent. The Authority classified the products under heading 2106 90 as food preparations not elsewhere specified, attracting 18 percent GST, because the mixing and added ingredients took them out of the concessional flour entries. The Appellate Authority upheld that classification.
Practical effect: Chennai food manufacturers selling instant mixes should confirm whether the product is a plain flour or a preparation before applying 5 percent.
