Iyyappanthangal sits on Mount Poonamallee Road beside its MTC bus depot, in the hospital shadow of the Porur medical belt, with pharmacies, diagnostic collection centres, supermarkets and apartment builders filling the frontage towards Kattupakkam and Mangadu. Builders selling under-construction flats at the 1 and 5 per cent rates without input tax credit, and pharmacies handling 5, 12 and 18 per cent medicine slabs, drive most GST queries. 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 Iyyappanthangal and neighbouring Porur and Kattupakkam, 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.
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.
We match your purchase register against GSTR-2B every period, follow up on invoices your suppliers have not uploaded, and ensure every rupee of eligible input tax credit is claimed. Clients routinely recover credit they were silently losing under self-filing.
Goods sent to job workers must move on delivery challans, return within the statutory period, and be reported in ITC-04. We track every outward and return leg for manufacturing clients in Iyyappanthangal, so inputs sent out for processing never quietly convert into a deemed supply carrying tax and interest.
You receive a WhatsApp message when documents are received, when the draft is ready for your approval, and when the return or application is filed, along with the acknowledgement. You never have to call and ask what is happening with your file.
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.
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.
Loan applications and government tenders routinely demand GST returns and registration documents. With everything filed and archived properly, you can produce a complete compliance file within hours instead of days.
You know your expected GST outflow days before the 20th, not on the night of filing. That advance visibility lets you plan payments, collections and bank balances instead of scrambling for funds at the deadline.
Amounts deducted by government buyers as GST TDS and by marketplaces as TCS are accepted on the portal each period, so money withheld against your GSTIN actually reaches your cash ledger instead of lying unclaimed.
Tax positions, rate choices and credit calls are documented as they are made, so if a question arises years later, the reasoning and evidence are on file rather than in someone's fading memory.
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.
Systematic GSTR-2B matching and supplier follow-up mean input tax credit that was leaking away under self-filing is captured each month, directly reducing the cash you pay out with every GSTR-3B.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| When a notice arrives | A professional drafts the reply in the department's format and files it within the statutory window, such as thirty days for ASMT-11. | You face departmental language alone, and a missed reply deadline can convert a simple query into a demand with penalty. |
| 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. |
| 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. |
| 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. |
| 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. |
Mahatma Gandhi Street is a residential street in Iyyappanthangal, about 1.3 km north of the centre of Iyyappanthangal. The same consultant covers the streets immediately around it — Kamaraj Street (about 50 m); Vivekanander Street (about 100 m); Santosh Bai Street (about 150 m); Ambethkar Street (about 150 m) — so a site visit on Mahatma Gandhi Street can usually be combined with other work in Iyyappanthangal on the same trip. For GST purposes an address on Mahatma Gandhi Street falls under the Chennai Outer CGST Commissionerate, and the Iyyappanthangal pincode is 600056.
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.
Notification No. 12/2017-Central Tax (Rate) dated 28.06.2017 · 2017-06-28
This notification lists the services that are wholly exempt from CGST. It covers charitable activities, most services supplied by and to Government, renting of residential dwellings for use as residence, healthcare by a clinical establishment, education by an educational institution, agricultural services, several transport exemptions and financial services such as interest on deposits and loans. Each entry has a description, a service code and often a condition. An exemption is not a zero rate: input tax credit attributable to exempt supplies has to be reversed.
How we apply it: If your Chennai business supplies anything on this list, you must reverse proportionate input tax credit under Rule 42 rather than simply enjoying a tax-free supply.
GSTN Advisory, 2022 — Phase-II of mandatory HSN reporting in Table 12 of GSTR-1 from 1 November 2022 · 2022-11-01
Mandatory HSN reporting in Table 12 of GSTR-1 was introduced in phases from 1 April 2022, when the portal began flagging missing or short codes in warning mode. In Phase-II, from the November 2022 return period, taxpayers with annual aggregate turnover up to Rs 5 crore had to report at least four-digit HSN codes for all business-to-business supplies in Table 12, and taxpayers above Rs 5 crore had to report six digits for all supplies. Phase-III in 2025 went further and replaced manual entry with selection from a dropdown of valid codes.
Why this matters: Correct HSN codes once at the item-master level, so that each successive tightening of portal validation does not force fresh rework.
Circular No. 69/43/2018-GST dated 26 October 2018 · 2018-10-26
This circular set out how officers must handle an application for cancellation of registration in FORM GST REG-16. The officer should verify the application and, if satisfied, pass the cancellation order in FORM GST REG-19 within thirty days. Pending returns are to be filed and any liability discharged, and the taxpayer must file the final return in FORM GSTR-10 within three months of the cancellation order. Cancellation cannot be refused merely because dues are outstanding.
What it means for you: A Chennai business closing down should file REG-16, clear pending returns and remember GSTR-10, since an unfiled final return keeps the liability alive.
