The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Maduravoyal 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 Rajas Garden — 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.
Finding dependable GSTR-1 & GSTR-3B Monthly Filing in Maduravoyal usually means choosing between a distant online portal and an overloaded local accountant. Maduravoyal is Chennai's western freight gateway where the Chennai Bypass meets Poonamallee High Road, filled with transporters, godowns, wholesale distributors and automobile service centres along the Vanagaram-Ambattur stretch. Goods transport agencies and their clients here regularly need reverse charge advice, e-way bill compliance for interstate loads and registration of rented warehouses as additional places of business. We offer a third option: a professional Chennai GST practice that treats Maduravoyal, Koyambedu and Vanagaram as home ground, responds the same working day, files ahead of deadlines, and stands behind its work if a notice ever arrives on a return we prepared.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
Send your query on call or WhatsApp and you hear back the same working day, usually within a few hours. When a due date is close or a notice has landed, waiting two days for a reply is simply not acceptable, and we know it.
Most GST notices trace back to mismatches between GSTR-1, GSTR-3B and GSTR-2B. We reconcile these before filing, not after a notice arrives, so your returns are internally consistent and the most common triggers for ASMT-10 scrutiny simply never appear.
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.
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 Maduravoyal never leave marketplace deductions unclaimed.
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.
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.
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.
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.
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.
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.
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.
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.
Correct, complete tax invoices signal a well-run business to customers, vendors and banks alike, quietly strengthening your credibility in every transaction where your paperwork is seen.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| Input tax credit | Purchase register matched against GSTR-2B each period, with defaulting suppliers chased so eligible credit is actually captured. | Credit claimed from books alone; mismatches with GSTR-2B mean lost credit or excess claims that invite departmental queries. |
| 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. |
| 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. |
| 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. |
| Late fees and interest | Filings go in ahead of statutory dates, so the Rs.50-per-day late fee and 18 percent interest never arise. | Late fees accumulate silently every delayed day, and interest on unpaid tax runs at 18 percent per annum. |
Positions we rely on when preparing filings and drafting replies — with the exact citation, so you can verify each one.
35th GST Council Meeting, New Delhi — 21 June 2019 · 2019-06-21
At the first meeting chaired by Finance Minister Nirmala Sitharaman, the Council decided to introduce an electronic invoicing system in a phase-wise manner for business-to-business transactions. The press release recorded that e-invoicing would help taxpayers with backward integration and automation of tax-relevant processes and would help authorities combat evasion, with Phase 1 proposed to be voluntary and rolled out from January 2020. This decision is the origin of the Invoice Registration Portal, the IRN and the QR code now mandatory for most mid-sized and large businesses.
Why this matters: Every later e-invoicing threshold reduction, down to the Rs 5 crore limit now applicable, traces back to this decision, so businesses crossing a threshold must set up e-invoicing from the first day of the next financial year.
GSTN Advisory dated 7 June 2025 — non-editable auto-populated liability in GSTR-3B · 2025-06-07
After an October 2024 advisory and a January 2025 deferment, GSTN confirmed that from the July 2025 tax period the auto-populated outward tax liability in GSTR-3B, drawn from GSTR-1, IFF or GSTR-1A, is hard-locked and cannot be edited manually while filing. Any correction to sales figures must be made through GSTR-1A before GSTR-3B is filed. The change is intended to end mismatches between GSTR-1 and GSTR-3B.
What to do about it: Reconcile sales data before filing GSTR-1 each month, since GSTR-3B can no longer be adjusted at the last minute.
Notification No. 07/2020-Central Tax · 2020-02-03
CBIC replaced the single 20th-of-the-month GSTR-3B deadline with a staggered system. Taxpayers with aggregate turnover of Rs 5 crore or more in the previous financial year continued to file by the 20th. Smaller taxpayers were split by State: those in Tamil Nadu and the other southern and western States were given the 22nd, while the northern and eastern States were given the 24th. The arrangement was first notified for the January to March 2020 returns.
How we apply it: A Chennai business below Rs 5 crore turnover files GSTR-3B by the 22nd, not the 20th, and late-fee notices computed from the 20th should be contested.
