Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
Late fees, blocked credit and mismatch notices cost far more than professional help ever will. We complete GSTR-1 & GSTR-3B Monthly Filing for Ayanavaram businesses from Rs.749, matching every figure against portal data before anything reaches the department.
We serve businesses on and around Konnur High Road — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

Ayanavaram sits beside the Integral Coach Factory's Carriage Works, and machining shops, hardware stores, printing units and provision retailers line Konnur High Road and Ayanavaram Road up to the ESI Hospital junction. Workshops supplying the Carriage Works have 2 per cent GST TDS deducted on contracts, so accepting GSTR-7 credits and keeping tender billing clean is the locality's recurring compliance chore. Years of working in and around Ayanavaram have shown us where GST trouble actually begins here — supplier defaults, classification doubts and deadlines lost in busy trading weeks. Our GSTR-1 & GSTR-3B Monthly Filing is built to close precisely those gaps, and the same team supports businesses in Perambur and Villivakkam, each with one point of contact and a compliance calendar maintained on their behalf.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
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.
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 Ayanavaram often discover in this first review exactly why their previous arrangement was costing them money.
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.
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.
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.
Your sales figures, supplier lists and login credentials are handled only by our engaged team, stored securely and never shared with any third party. Many of our clients in Ayanavaram compete with each other; complete confidentiality is a condition of our work.
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.
New branches, new product lines and interstate sales all carry GST consequences. With standing professional support, you expand knowing registrations, invoicing and returns will keep pace with the business.
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.
Because monthly data is reconciled as it happens, GSTR-9 preparation before the 31 December due date becomes a review exercise rather than a painful reconstruction of twelve untidy months.
Consistent, reconciled returns give the department's matching systems nothing to flag. Clients who move to us after years of self-filing typically see scrutiny queries and mismatch notices fall away within a few filing cycles.
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.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
Konnur High Road is a primary arterial road in Ayanavaram, about 1.2 km west of the centre of Ayanavaram. The same consultant covers the streets immediately around it — Vellala Street (about 400 m); Thrope Road (about 750 m); 1st Main Road (about 800 m); Bharathi Nagar (about 800 m) — so a site visit on Konnur High Road can usually be combined with other work in Ayanavaram on the same trip. For GST purposes an address on Konnur High Road falls under the Chennai North CGST Commissionerate, and the Ayanavaram pincode is 600023.
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.
9th GST Council Meeting, New Delhi — 16 January 2017 (Signed Minutes, Agenda Item 3) · 2017-01-16
The dual-control deadlock that had stalled several earlier meetings was broken. The Council agreed that taxpayers would be divided between Central and State tax administrations for all administrative purposes: of taxpayers with turnover below Rs 1.5 crore, 90 per cent would go to the State administration and 10 per cent to the Centre, while taxpayers above Rs 1.5 crore would be split equally. Division was to be by computerised stratified random sampling at the State level, with both administrations retaining intelligence-based enforcement powers over the whole value chain. West Bengal recorded its dissent.
What it means for you: This is why a Chennai taxpayer is assigned either to the Tamil Nadu Commercial Taxes Department or to CGST Chennai, and why notices come from only one of them for routine matters.
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.
Nithiyashree Ladies Hostel - AAR Tamil Nadu, Advance Ruling No. 77/AAR/2023, dated 4 September 2023 · 2023-09-04
The applicant ran a ladies hostel in premises it had itself taken on rent and supplied accommodation together with food and related services. It sought exemption on the footing that this was renting of residential accommodation. The Authority held the supply classifiable under heading 9963 and taxable at 9 percent central tax and 9 percent State tax, treating hostel accommodation with attached services as a taxable service and not as renting of a residential dwelling for use as a residence.
Practical effect: Chennai hostel and paying guest operators should not assume exemption; the outcome turns on the exact facts and on later High Court rulings.
