The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Thirumangalam 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 Anna Street — 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.
Businesses in Thirumangalam looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. Thirumangalam junction, where Jawaharlal Nehru Salai meets Anna Nagar 2nd Avenue beside the metro station and VR Chennai mall, has become a showroom strip for jewellery, textiles, furniture and electronics chains spilling into Anna Nagar West Extension. High-volume B2C billing with occasional B2B orders makes correct GSTR-1 bifurcation and e-invoice applicability checks the daily compliance concern for retailers here. We serve this belt — including Anna Nagar and Mogappair — 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.
In the days before the 11th and the 20th, our team runs extended hours and a strict internal queue, so a client who sends data late in the window is still filed on time. Peak-season crush at our end never becomes a late fee at yours.
Traders, manufacturers, contractors, e-commerce sellers, professionals and service exporters — we have handled GST for all of them. Whatever mix of goods and services your Thirumangalam business supplies, the rate, classification and place-of-supply questions have almost certainly crossed our desk before.
Goods sent to job workers must move on delivery challans, return within the statutory period, and be reported in ITC-04. We track every outward and return leg for manufacturing clients in Thirumangalam, so inputs sent out for processing never quietly convert into a deemed supply carrying tax and interest.
Composition dealers have their own rulebook — CMP-08 every quarter, GSTR-4 annually by 30 June, bills of supply instead of tax invoices, and a turnover ceiling that must be watched. We handle each of these correctly so the scheme's simplicity never turns into a violation.
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.

Practical outcomes our clients measure us by.
When a query or verification comes, you respond through a professional who deals with the department regularly, in the department's own language and format, instead of facing an officer's letter alone.
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.
Advances received for services attract GST on receipt while advances for goods generally do not; applying this distinction correctly means you neither prepay tax unnecessarily nor omit a liability that surfaces later with interest.
A fixed professional fee is almost always cheaper than the combination of late fees, interest, lost credit and staff hours that informal, last-minute compliance quietly accumulates over a year.
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.
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.
| 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. |
| Keeping up with changes | Rate changes, portal updates and new thresholds such as the Rs.5 crore e-invoice limit are tracked by us and applied to your case proactively. | Changes are discovered after the fact — often through a rejected filing, a blocked e-way bill or a departmental letter. |
| 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. |
| 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. |
| 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. |
| 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. |
Anna Street is a residential street in Thirumangalam, about 800 m west of the centre of Thirumangalam. The same consultant covers the streets immediately around it — Ambedkar Street (about 100 m); V.O.C. Street (about 200 m); Rajaji Street (about 250 m); Kamarajar Street (about 300 m) — so a site visit on Anna Street can usually be combined with other work in Thirumangalam on the same trip. For GST purposes an address on Anna Street falls under the Chennai North CGST Commissionerate, and the Thirumangalam pincode is 600040.

18th GST Council Meeting, New Delhi — 30 June 2017 (Signed Minutes, Agenda Item 3) · 2017-06-30
Meeting on the day GST was launched, the Council revisited the rate on fertilisers. Officers calculated the pre-GST incidence at about 9.75 per cent, placing fertilisers between the five and twelve per cent slabs. After almost every State supported relief for farmers, the Chairperson recorded a consensus and the Council agreed to tax fertilisers at five per cent instead of twelve, notwithstanding the inverted duty refund burden this would create for manufacturers whose inputs were taxed at eighteen per cent.
Why this matters: The Council reopened a rate it had already fixed only weeks earlier, and the cut created the inverted duty structure that fertiliser dealers still claim refunds under.
TVH Lumbini Square Owners Association - AAR Tamil Nadu, Order No. 25/ARA/2019, dated 21 June 2019 · 2019-06-21
A residents welfare association collected monthly maintenance contributions from its members. The Authority held that where the contribution per member exceeds Rs. 7,500 a month, GST is payable on the entire contribution and not merely on the amount above Rs. 7,500. The Madras High Court subsequently held, in Greenwood Owners Association, that only the excess over Rs. 7,500 is taxable, and associations now follow that judicial position.
Why this matters: Chennai apartment associations should apply the High Court position carefully and keep member-wise workings ready for departmental scrutiny.
Notification No. 34/2021-Central Tax · 2021-08-29
Where the due date for filing an application for revocation of cancellation of registration under Section 30, read with Rule 23, fell between 1 March 2020 and 31 August 2021, the application could be filed up to 30 September 2021. The relief was confined to registrations cancelled for non-filing of returns under clause (b) or clause (c) of Section 29(2). Taxpayers still had to file all pending returns and pay the tax, interest, penalty and late fee before the application could be allowed.
Why this matters: This was the escape route for Chennai businesses whose GSTIN was cancelled during the pandemic, and it established the pattern of periodic revocation windows.
