Businesses in Poonamallee looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. Poonamallee, where Trunk Road meets the Chennai-Bengaluru highway, is the gateway to the Sriperumbudur industrial belt: plant nurseries, timber and building material depots, lorry operators and college-linked hostels spread through Kumananchavadi, Karayanchavadi and Senneerkuppam. Nurseries selling exempt live plants alongside taxable pots and manure, and consignors missing reverse charge on lorry freight, are the recurring GST issues here. We serve this belt — including Avadi and Thiruverkadu — with fixed fees quoted upfront, a written document checklist, and filings completed ahead of statutory due dates. Every acknowledgement is shared the day it is generated, and our support continues if the department raises any query on work we have filed.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
Every acknowledgement, challan, computation sheet and filed return is saved and shared with you in an organised folder. When a bank, buyer or GST officer asks for a document from two years ago, it reaches you the same day without any scrambling.
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.
Every new client receives a review of their recent returns before we file anything — unclaimed credit, GSTR-1 versus GSTR-3B drift, and exposures worth correcting quietly. Businesses in Poonamallee often discover in this first review exactly why their previous arrangement was costing them money.
Freight paid to transporters, advocate fees, imported services and other notified supplies attract GST under reverse charge, with self-invoicing where the supplier is unregistered. We maintain a running RCM check every period, because this is the liability self-filers most consistently miss.
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.
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.
When a business winds up, proper cancellation and a timely final return ensure the file is genuinely closed, so no demand or late-fee computation resurfaces against you long after the shutters came down.
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.
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.
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.
Funding rounds, partnerships and business sales all begin with a compliance check. A clean, documented GST history lets you clear that scrutiny quickly instead of watching a deal stall over old filing gaps.
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.
| 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. |
| 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. |
| 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. |
| When a notice arrives | A professional drafts the reply in the department's format and files it within the statutory window, such as thirty days for ASMT-11. | You face departmental language alone, and a missed reply deadline can convert a simple query into a demand with penalty. |
| 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. |
| 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. |
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
Notification No. 05/2017-Central Tax dated 19.06.2017 · 2017-06-19
This notification exempts from obtaining registration those persons who supply only goods or services on which the entire tax is payable by the recipient under reverse charge in terms of section 9(3) of the CGST Act. Typical beneficiaries are small goods transport agencies, individual advocates, and persons supplying only notified reverse charge items, because the recipient discharges the tax and the supplier has no output liability to report.
Why this matters: A Chennai transporter or advocate whose entire turnover is covered by reverse charge need not take GST registration, however genuinely mixed turnover destroys this exemption.
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.
What to do about it: Update your billing software's HSN masters so every item carries a valid 4 or 6 digit code that matches the portal dropdown.
27th GST Council Meeting (video conference) — 4 May 2018 (PIB Release ID 1531331) · 2018-05-04
Acting on the report of the Group of Ministers on IT simplification, the Council approved the design principles for a new return: one monthly return for all taxpayers except composition dealers and a few others, with staggered due dates by turnover; unidirectional flow of invoices uploaded by the seller at any time during the month, which would be the valid document for the buyer's credit; no requirement to upload purchase invoices; four-digit HSN for B2B invoices; and automatic computation of liability and credit.
What to do about it: The upload-lock-pay idea behind today's auto-populated GSTR-2B and GSTR-3B originates in these principles.
