Porur commands the junction of Mount Poonamallee Road and Arcot Road, the gateway to Chennai's western IT corridor, with the Sri Ramachandra medical campus, IT offices, construction firms and logistics yards nearby. IT and ITES exporters need LUT filings under RFD-11 each financial year and refunds through RFD-01, while contractors face Section 17(5) credit blocks and site-to-site e-way bills. 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 Porur and neighbouring Valasaravakkam and Ramapuram, 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.
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 Porur never leave marketplace deductions unclaimed.
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.
When an ADT-01 audit intimation or a personal hearing date arrives, we compile the records, prepare the reconciliations and draft the submissions, and coordinate closely with your authorised representative. You walk into the proceeding prepared, not improvising in front of an officer.
No filing leaves our desk on a junior's judgement alone. A senior GST practitioner reviews your figures, ITC claims and tax computation before submission, so errors are caught at our table and not by the department months later through a notice.
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 Porur never writes back to you as a demand years later.
GST is confusing enough without a language barrier. Our team explains notices, tax positions and filing requirements in plain Tamil or English, whichever you and your staff in Porur are comfortable with, and keeps written communication simple and jargon-free.
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.
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.
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.
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.
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.
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.
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.
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
11th Street is a residential street in Porur, about 650 m south of the centre of Porur. The same consultant covers the streets immediately around it — Mount Poonamallee Highway (about 250 m); 2nd Crosss Street (about 400 m); 1st Cross Street (about 400 m); Mount - Poonamallee - Avadi Road (about 550 m) — so a site visit on 11th Street can usually be combined with other work in Porur on the same trip. For GST purposes an address on 11th Street falls under the Chennai South CGST Commissionerate, and the Porur pincode is 600116.

GST law moves through notifications, circulars and court decisions. These are the ones changing how filings are prepared right now.
Megha Engineering and Infrastructures Ltd v. Commissioner of Central Tax — Telangana High Court, judgment dated 18 April 2019 · 2019-04-18
The taxpayer filed GSTR-3B late and paid interest only on the net cash portion of the tax. The High Court held that on the language of Section 50 as it then stood, interest ran on the gross liability, because input tax credit is credited to the ledger only when the return is filed. The decision caused wide concern in trade, and Parliament later amended Section 50 with retrospective effect from 1 July 2017 to charge interest only on the cash component in most late-return cases.
How we apply it: For late returns, interest is now generally computed on the cash portion only — if an older notice demands interest on gross tax, rely on the retrospective proviso to Section 50.
Notification No. 31/2020-Central Tax · 2020-04-03
For the February, March and April 2020 tax periods CBIC lowered the interest rate on late GSTR-3B payment. Taxpayers with aggregate turnover above Rs 5 crore paid no interest for the first fifteen days after the due date and nine per cent thereafter, provided the return was filed by 24 June 2020. Taxpayers with turnover up to Rs 5 crore paid no interest at all if they filed within the extended dates specified for their turnover slab.
What it means for you: Interest demands for February to April 2020 must be recomputed under this concessional table, and many DRC-01 interest computations for that period are simply wrong.
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.
What to do about it: Chennai hostel and paying guest operators should not assume exemption; the outcome turns on the exact facts and on later High Court rulings.
