Chennai's dedicated GST practice · GSTR-1 due 11th · GSTR-3B due 20th/22nd
The 11th and the 20th arrive every month whether you are ready or not. Our Chennai team keeps businesses in Kattupakkam 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 Astalakshmi Nagar — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.

Kattupakkam fronts Mount Poonamallee Road between Kumananchavadi and Karayanchavadi, with Audco Nagar and Astalakshmi Nagar behind Queen Victoria Road and the Poonamallee-Kundrathur-Pallavaram Road feeding godowns, timber depots and auto workshops. Hardware dealers, packers and movers, transport fleets, schools and hospital suppliers file from here. E-way bill mismatches on the old NH4 corridor, goods transport agency reverse charge and composition-to-regular transitions for traders crossing the turnover limit recur constantly. 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 Kattupakkam and neighbouring Iyyappanthangal and Poonamallee, 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.
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.
You deal with one accountable person who knows your business, your turnover pattern and your filing history. No repeating your story to a new voice every month, and no file falling between two desks when a deadline is approaching.
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.
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.
Quarterly filing still demands monthly attention — IFF uploads so your buyers see their credit on time, and tax payment through PMT-06 by the 25th for the first two months of each quarter. We run that monthly rhythm so QRMP saves you effort without creating gaps.
Businesses with registrations in more than one State, or multiple branches under one PAN, face cross-charge, stock transfer and input service distribution questions that single-GSTIN firms never see. We keep all your registrations consistent with each other, not just compliant individually.
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.

Rs.7,999/year
Practical outcomes our clients measure us by.
Your scheme choice — regular, composition or QRMP — is re-examined as turnover and margins change, so you are always paying under the structure that legitimately costs your business the least.
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.
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.
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.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| Input tax credit | Purchase register matched against GSTR-2B each period, with defaulting suppliers chased so eligible credit is actually captured. | Credit claimed from books alone; mismatches with GSTR-2B mean lost credit or excess claims that invite departmental queries. |
| 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. |
| 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. |
| 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. |
GST law moves through notifications, circulars and court decisions. These are the ones changing how filings are prepared right now.
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.
Why this matters: 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.
GSTN Advisory dated 25 April 2025 — Phase-III of HSN reporting in Table 12 of GSTR-1/1A · 2025-04-25
GSTN implemented Phase-III of mandatory HSN reporting in Table 12 of GSTR-1 and GSTR-1A from the May 2025 return period, after the change was deferred from earlier periods. Manual keying of HSN codes is replaced by selection from a dropdown, Table 12 is split into separate B2B and B2C tabs, and new value validations compare the taxable values reported across tables. Table 13, the summary of documents issued, also became mandatory. Taxpayers up to Rs 5 crore turnover report 4-digit codes; larger taxpayers report 6-digit codes.
Practical effect: Update your billing software's HSN masters so every item carries a valid 4 or 6 digit code that matches the portal dropdown.
Notification No. 2/2017-Central Tax (Rate), dated 28 June 2017 (G.S.R. 674(E)) · 2017-06-28
This companion notification exempted intra-State supplies of listed goods from central tax altogether, covering fresh vegetables and fruit, unbranded cereals and pulses, milk, curd, salt, live animals, human blood, printed books, judicial stamp paper and many agricultural items. Suppliers dealing only in these goods make exempt supplies, cannot claim input tax credit on related purchases, and must reverse credit under Rule 42 where inputs are common. It was superseded with effect from 22 September 2025.
Practical effect: A Chennai trader dealing in exempt goods should not charge GST on them, but must equally accept that input credit on the related expenses is not available.
