Nandambakkam, on Mount-Poonamallee Road beside the Adyar river, is defined by the Chennai Trade Centre exhibition complex and the Officers Training Academy belt near St. Thomas Mount. Exhibition organisers, stall fabricators, caterers and AV rental firms work event cycles here, wrestling with 18 per cent GST on stall licensing, place-of-supply rules for out-of-state exhibitors and input tax credit on temporary structures. From a first registration to the annual return, the full range of GSTR-1 & GSTR-3B Monthly Filing is available to Nandambakkam businesses without stepping far from the shop or office — documents travel over WhatsApp, and our Chennai premises are open to anyone who prefers a face-to-face discussion. We serve St. Thomas Mount and Guindy on the same footing, applying one rule everywhere: reconcile before filing, file before the due date, and keep the client informed at every stage.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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 Nandambakkam. 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.
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 Nandambakkam never writes back to you as a demand years later.
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 Nandambakkam never leave marketplace deductions unclaimed.
OTP failures, DSC errors, stuck submissions on due-date evenings — we deal with the GST portal daily and know the workarounds. When the site misbehaves on the 20th, our team keeps retrying and escalating so your return still goes through.
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
Rs.7,999/year
Practical outcomes our clients measure us by.
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.
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.
Rates, reverse charge, place of supply and blocked credits are applied correctly at the preparation stage, so you neither overpay tax you do not owe nor underpay and invite demands with penalty later.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
Your billing staff are guided on invoice fields, rates and series discipline, so mistakes are prevented where they originate — at the counter — instead of being repaired later in the returns.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| Refund claims | RFD-01 filed with complete statements and annexures, tracked from ARN to bank credit, with any deficiency memo answered promptly. | Incomplete claims bounce back as deficiency memos while the refund sits unclaimed for months and working capital stays blocked. |
| 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. |
| 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. |
5th Cross is a residential street in Nandambakkam, about 650 m west of the centre of Nandambakkam. The same consultant covers the streets immediately around it — 4th Cross (about 0 m); 6th Cross (about 50 m); 3rd Cross (about 50 m); 2nd Cross (about 50 m) — so a site visit on 5th Cross can usually be combined with other work in Nandambakkam on the same trip. For GST purposes an address on 5th Cross falls under the Chennai South CGST Commissionerate, and the Nandambakkam pincode is 600089.

17th GST Council Meeting, New Delhi — 18 June 2017 (PIB Release ID 1493128) · 2017-06-18
Responding to trade concerns about return readiness, the Council decided that for the first two months of GST, tax would be payable on a simple summary return, Form GSTR-3B, filed by the 20th of the following month. Invoice-wise details in GSTR-1 for July 2017 were to be filed between 1 and 5 September and for August between 16 and 20 September, with GSTR-2 auto-populated thereafter. This is the origin of the summary return that has governed monthly GST compliance ever since.
How we apply it: GSTR-3B was designed as a two-month stopgap and is still the return every Chennai business files monthly, which is why its legal status has been litigated repeatedly.
GSTN Advisory dated 31 August 2023 — Electronic Credit Reversal and Re-claimed Statement · 2023-08-31
GSTN introduced the Electronic Credit Reversal and Re-claimed Statement on the portal to track credit reversed in Table 4B(2) of GSTR-3B and later reclaimed in Tables 4D(1) and 4A(5). It applied from the August 2023 return for monthly filers and from the July to September 2023 quarter for quarterly filers. The cumulative opening balance of reversals awaiting reclaim had to be reported by 30 November 2023, with up to three amendments allowed until 31 December 2023. The portal now warns when reclaimed credit exceeds the available balance.
Practical effect: Maintain a running register of credit reversed and reclaimed, because the portal flags excess reclaims and the data feeds departmental scrutiny.
Rule 59(6), CGST Rules, 2017, inserted by Notification No. 94/2020-Central Tax · 2020-12-22
Rule 59(6) was inserted so that a monthly filer who has not furnished GSTR-3B for the preceding two months cannot file GSTR-1, and a quarterly filer who has not furnished the return for the preceding tax period cannot file GSTR-1 or use the invoice furnishing facility. A person restricted under Rule 86B who has not filed the immediately preceding GSTR-3B is likewise blocked. The restriction was actually switched on at the portal from 1 September 2021, and Notification No. 35/2021-Central Tax later reduced the trigger from two preceding months to the immediately preceding month with effect from 1 January 2022. The same notification also lengthened e-way bill validity computation to two hundred kilometres a day and extended registration processing where physical verification is ordered.
What to do about it: One missed GSTR-3B in a Chennai business now stops the outward statement as well, which in turn stops the customers' credit and quickly escalates into commercial pressure.
