The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Mudichur 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 Kaveriyamman Kovil Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

Mudichur's construction boom along the Tambaram - Mudichur - Sriperumbudur Road and the Outer Ring Road has filled former paddy fields with apartment projects, plot promotions, building material yards, hardware and paint shops, water-can suppliers and packers-and-movers out to Varadharajapuram and Mannivakkam. Construction is the GST epicentre here: rate confusion on works contracts, the eighty per cent registered-purchase rule for promoters, and flood-season filing relief. Against that backdrop, GSTR-1 & GSTR-3B Monthly Filing in Mudichur demands more than data entry — it needs reconciliation before filing, correct classification and awareness of what local officers examine. Our Chennai team provides exactly that to clients in Mudichur, Perungalathur and Varadharajapuram, with same-day responses on working days and WhatsApp updates at every stage. Most routine engagements complete within one to two working days once documents are in hand.
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.
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.
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.
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 Mudichur never writes back to you as a demand years later.
From filing the LUT in RFD-11 at the start of each financial year to preparing RFD-01 refund claims with complete annexures, we know what makes a refund file move. Exporters and inverted-duty businesses come to us specifically for this.
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.

Practical outcomes our clients measure us by.
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.
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.
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.
Each period you receive a simple computation showing output tax, credit utilised and net cash payable, so GST becomes a number you understand and question rather than a figure you accept blindly.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Kaveriyamman Kovil Street is a residential street in Mudichur, about 1.9 km north-east of the centre of Mudichur. The same consultant covers the streets immediately around it — Chelliyamman Kovil Cross Street (about 50 m); Anna Street (about 100 m); Kattabomman Street (about 100 m); Indira Gandhi Salai (about 150 m) — so a site visit on Kaveriyamman Kovil Street can usually be combined with other work in Mudichur on the same trip. For GST purposes an address on Kaveriyamman Kovil Street falls under the Chennai Outer CGST Commissionerate, and the Mudichur pincode is 600048.
Road classification and position from OpenStreetMap; distances are straight-line and approximate. Jurisdiction must be confirmed on your own registration certificate.
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
GSTN Advisories No. 624 dated 27 September 2025 and No. 631 dated 17 October 2025 — IMS enhancements from the October 2025 tax period · 2025-10
GSTN enhanced the Invoice Management System from the October 2025 tax period. Recipients can now keep credit notes and specified records pending for one tax period instead of being forced to accept or reject them immediately, can declare the actual amount of input tax credit to be reduced when accepting a credit note where the credit was never availed or was already reversed, and can save remarks when rejecting or keeping a document pending. GSTR-2B can be recomputed after corrective action is taken.
Practical effect: Train your accounts team on the new pending and partial-reversal options so supplier credit notes do not strip more ITC than legally required.
Bharat Sanchar Nigam Ltd v. Union of India — Supreme Court, (2006) 3 SCC 1, judgment dated 02-03-2006 · 2006-03-02
The Supreme Court held that the same transaction may have a goods aspect and a service aspect, and different legislatures may tax different aspects, but the same element cannot be taxed twice. A composite contract cannot be split into goods and services except in the cases specifically permitted by Article 366(29A), such as works contracts and catering. The dominant nature test was applied to decide the character of the contract.
How we apply it: Chennai businesses with bundled offerings should determine the dominant character of the supply, since that decides classification and rate under GST.
Notification No. 15/2021-Central Tax (Rate) dated 18.11.2021 · 2021-11-18
This notification removed the words governmental authority and government entity from the concessional works contract entries in the services rate notification. With effect from 1 January 2022, works contract services supplied to a governmental authority or a government entity ceased to enjoy the 12 per cent rate and moved to 18 per cent with input tax credit. Only supplies made directly to the Central Government, a State Government, a Union territory or a local authority continued at the concessional rate at that stage.
What it means for you: Chennai contractors working for boards, corporations and government companies moved to 18 per cent from 1 January 2022, and should have raised price-variation claims for contracts signed earlier.
