Mangadu's economy revolves around the Kamakshi Amman temple: flower and garland sellers, pooja article shops, silk saree and jewellery showrooms and sweet stalls crowd Sannathi Street and the Mangadu-Kundrathur Road, with new apartment projects towards Paraniputhur. Traders mixing exempt fresh flowers with taxable garlands, prasadam counters and gold savings schemes must split exempt and taxable turnover correctly in GSTR-1. For businesses here, staying on the right side of GST is not optional — buyers check compliance, and the department's systems match every return. Our firm provides GSTR-1 & GSTR-3B Monthly Filing to clients across Mangadu and neighbouring Porur and Kundrathur, combining Chennai jurisdiction familiarity with disciplined deadline tracking. Whether you run a shop, a service practice or a growing trading concern, we handle the portal work so you can stay focused on the business itself.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
Tally, Zoho Books, Busy, marketplace reports, plain Excel or even a handwritten bill book — we take your data in whatever form your Mangadu business already maintains it. You are never forced to buy new software or retrain staff just to become our client.
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 Mangadu always know exactly what the engagement costs them.
GSTR-1 by the 11th, GSTR-3B by the 20th, CMP-08 by the 18th after each quarter — we maintain a compliance calendar for every client and start chasing your data well before the due date, so late fees never enter the picture.
Whenever the GST Council notifies a late-fee waiver or an amnesty window for pending returns or old demands, we check every client's history against it and act within the deadline. Relief that businesses in Mangadu would otherwise read about after it lapsed reaches our clients in time.
New GSTIN applications, core field amendments through REG-14, additional places of business — we prepare complete, query-resistant applications the first time. Clean paperwork is the difference between smooth approval and weeks lost answering clarification memos from the department.
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.
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.
Loan applications and government tenders routinely demand GST returns and registration documents. With everything filed and archived properly, you can produce a complete compliance file within hours instead of days.
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.
Large buyers check vendor GST compliance before releasing payments and renewing contracts. A clean filing record with timely GSTR-1 uploads keeps your invoices reflecting in their GSTR-2B and your payments unblocked.
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.
E-commerce platforms continuously validate seller GSTINs and filing status. A consistently compliant registration keeps your listings active and settlements flowing, with no sudden suspension of your online sales channel.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Shriram City Road is a residential street in Mangadu, about 650 m south-east of the centre of Mangadu. The same consultant covers the streets immediately around it — Permual Koil Street (about 400 m); Palandeeswarar Koil Street (about 500 m); Walaja Street (about 700 m); Poonamallee - Kundrathur - Pallavaram Road (about 700 m) — so a site visit on Shriram City Road can usually be combined with other work in Mangadu on the same trip. For GST purposes an address on Shriram City Road falls under the Chennai Outer CGST Commissionerate, and the Mangadu pincode is 600122.

GST law moves through notifications, circulars and court decisions. These are the ones changing how filings are prepared right now.
Notification No. 28/2023-Central Tax · 2023-07-31
This notification appointed 1 October 2023 as the date for most GST amendments of the Finance Act 2023. The most consequential change bars taxpayers from filing GSTR-1, GSTR-3B, GSTR-9 and GSTR-8 after three years from their due date. The GST portal began actually blocking such time-barred returns from the July 2025 tax period, permanently freezing any unfiled compliance older than three years along with the credit flowing from it.
What it means for you: Any return more than three years past its due date can no longer be filed at all, so clear historic backlogs immediately rather than assuming they can be regularised later.
Union of India v. Bharti Airtel Ltd — Supreme Court, 2021 · 2021-10-28
Bharti Airtel sought to rectify its GSTR-3B for July-September 2017 to claim refund of about Rs 923 crore excess cash paid, blaming the non-operational GSTR-2A at the time. The Supreme Court set aside the Delhi High Court order permitting rectification, holding that returns can only be corrected in the period in which errors are noticed, as the law then stood, and that taxpayers must self-assess from their own books, not the portal.
What it means for you: File GSTR-3B accurately the first time — correct discovered errors in the current period per the prescribed mechanism rather than expecting retrospective revision of old returns.
36th GST Council Meeting (video conferencing) — 27 July 2019 · 2019-07-27
The Council reduced GST on all electric vehicles from 12 per cent to 5 per cent and on chargers or charging stations for electric vehicles from 18 per cent to 5 per cent. Hiring of electric buses with carrying capacity of more than twelve passengers by local authorities was exempted. All these changes took effect from 1 August 2019. The Council also extended the last date for opting into the six per cent service composition scheme in CMP-02 to 30 September 2019.
Why this matters: Electric vehicle dealers and charging point operators in Chennai bill at five per cent, a rate that has survived every later rate revision including GST 2.0.
