Choosing GSTR-1 & GSTR-3B Monthly Filing in Nanmangalam is ultimately an act of trust: you are handing over sales figures, purchase records and portal access. Nanmangalam, ringed by the Nanmangalam Reserve Forest and its worked-out quarries, hosts blue-metal crushers, M-sand and ready-mix depots, lorry fleets and building-material yards along Dr. Ambedkar Main Road, Vadakkupattu Road and S.I.V.E.T. College Road towards Medavakkam Koot Road. Reverse charge on mining royalty and seigniorage, and e-way bills for short-haul aggregate lorries, are the recurring disputes here. We earn that trust the unglamorous way — fixed fees honoured, drafts approved by you before filing, acknowledgements shared the same day, and strict confidentiality throughout. Clients across Nanmangalam, Kovilambakkam and Medavakkam have stayed with us for years on precisely this basis.
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 Nanmangalam never leave marketplace deductions unclaimed.
Freight paid to transporters, advocate fees, imported services and other notified supplies attract GST under reverse charge, with self-invoicing where the supplier is unregistered. We maintain a running RCM check every period, because this is the liability self-filers most consistently miss.
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.
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.
From filing the LUT in RFD-11 at the start of each financial year to preparing RFD-01 refund claims with complete annexures, we know what makes a refund file move. Exporters and inverted-duty businesses come to us specifically for this.
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.
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.
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.
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.
Funding rounds, partnerships and business sales all begin with a compliance check. A clean, documented GST history lets you clear that scrutiny quickly instead of watching a deal stall over old filing gaps.
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.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |

A working knowledge of recent instruments and judgments is what separates a defensible filing from a risky one.
Vishnu Aroma Pouching (P) Ltd v. Union of India — Gujarat High Court, Special Civil Application No. 5629 of 2019, judgment dated 21 October 2019 · 2019-10-21
Owing to a mistake, the company's GSTR-3B for one month was filed showing nil figures even though the tax had actually been paid, and the portal offered no way to correct it. The department refused rectification. The High Court held that a taxpayer cannot be left without a remedy for a bona fide error where the tax was in fact paid and no revenue was lost, and directed the authorities to allow the correction so that the liability and the recipient's credit were properly reflected.
What it means for you: A genuine reporting error in GSTR-3B is worth pressing before the department rather than absorbing — courts have ordered correction where no tax was actually short paid.
GSTN Advisory dated 23 August 2024 — introduction of the RCM Liability/ITC Statement · 2024-08-23
GSTN introduced a new RCM Liability and ITC Statement on the portal so that reverse charge tax declared in Table 3.1(d) of GSTR-3B can be matched against the corresponding credit claimed in Table 4A(2) and 4A(3). It applies from the August 2024 tax period for monthly filers and from the July to September 2024 quarter for taxpayers under the quarterly scheme. Taxpayers were required to report an opening balance of reverse charge liability paid but credit not yet claimed, or credit claimed without payment, within the window announced by GSTN.
Why this matters: Reconcile reverse charge payments with the credit taken every month, since the department can now see an RCM ledger for your GSTIN.
Entry 74, Notification No. 12/2017-Central Tax (Rate) dated 28.06.2017 · 2017-06-28
Entry 74 exempts health care services provided by a clinical establishment, an authorised medical practitioner or paramedics, and the transportation of a patient in an ambulance. Health care services are defined as diagnosis, treatment or care for illness, injury, deformity, abnormality or pregnancy in any recognised system of medicine, and expressly exclude cosmetic or plastic surgery unless done to restore or reconstruct anatomy affected by injury or congenital defect. Hair transplant and purely cosmetic procedures are therefore taxable.
Why this matters: A Chennai hospital or clinic is exempt on treatment, but must charge GST on cosmetic procedures, pharmacy sales to outsiders and rental of space to shops.
