Businesses in Mogappair looking for GSTR-1 & GSTR-3B Monthly Filing want two things: work done correctly and someone answerable when questions come. Mogappair, officially Dr. J.J. Nagar, is a healthcare and residential hub where the Madras Medical Mission hospital, multi-speciality clinics, diagnostic labs and pharmacies line Ambattur Industrial Estate Road and the East and West blocks. Hospitals and clinics supplying exempt healthcare alongside taxable pharmacy and canteen sales must apportion input tax credit between the two, the locality's most frequent GST question. We serve this belt — including Ambattur and Anna Nagar — 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.
Your cash ledger, credit ledger and liability register are reviewed regularly, not just at filing time. Excess balances are flagged for use or refund, and where a genuine slip surfaces, a voluntary payment through DRC-03 settles it before it can mature into a notice.
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.
Your work is executed by trained GST staff working under direct senior supervision, not passed to interns learning on your file. The person preparing your return understands reverse charge, blocked credits and place of supply, because getting these wrong costs you money.
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.
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.
We tell you when the composition scheme stops making sense, when QRMP suits your cash flow, and when a supplier's non-compliance is quietly costing you credit. Filing is the minimum; helping you make better GST decisions is the actual job.
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.
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.
With returns filed ahead of the statutory due dates every period, the Rs.50-per-day GSTR-3B late fee simply stops appearing in your life, and the money stays in your business where it belongs.
E-commerce platforms continuously validate seller GSTINs and filing status. A consistently compliant registration keeps your listings active and settlements flowing, with no sudden suspension of your online sales channel.
Late-fee waivers and amnesty windows notified by the GST Council are applied to your history within their deadlines, capturing reliefs that most businesses only hear about once the window has already closed.
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 |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
GSTN Advisory, 2021 — negative liability appearing in Form GSTR-4 filed by composition taxpayers · 2021
Composition taxpayers who left Table 6 of the annual return GSTR-4 blank found that the tax already paid through Form CMP-08 was treated as an excess payment, creating a negative liability that was then adjusted against later quarters. GSTN clarified that outward supply and reverse charge figures must be entered in Table 6 even though the tax has already been paid, and arranged for wrongly created negative balances to be reversed.
How we apply it: Composition dealers in Chennai must complete Table 6 of GSTR-4 each year, or the portal will show a false credit and later recover it.
Notification No. 8/2018-Central Tax (Rate), dated 25 January 2018 · 2018-01-25
This notification gave second-hand vehicle dealers a concessional rate charged not on the sale price but on the margin, that is the difference between the selling price and the purchase price, or the depreciated value where depreciation was claimed under the Income-tax Act. The concession applied only if the supplier had not availed input tax credit on the vehicle, and where the margin is negative no GST is payable. Compensation cess on such vehicles was separately exempted.
How we apply it: A used-car dealer in Chennai pays GST only on the mark-up, so accurate purchase and sale records for each vehicle are the whole defence in an audit.
Circular No. 177/09/2022-TRU · 2022-08-03
The Board answered a set of service classification and exemption questions arising from the 47th GST Council meeting. Most importantly for property transactions, it confirmed that the sale of land after levelling and after laying drainage, water and electricity lines remains a sale of land under Schedule III and is outside GST, while development services such as levelling and laying of drainage lines that the developer itself receives from contractors attract GST at the applicable rate. Several other exemption and rate questions on specified services were also settled.
Practical effect: Chennai plot developers can rely on this circular for the position that a plot sale price is not taxable, but must still bear GST on the development works they buy in from contractors.
