Late fees, blocked credit and mismatch notices cost far more than professional help ever will. We complete GSTR-1 & GSTR-3B Monthly Filing for Adyar businesses from Rs.749, matching every figure against portal data before anything reaches the department.
We serve businesses on and around 10th Cross Street — document pickup, in-person consultation at our Porur office, or fully online over WhatsApp.
Share your number — a senior GST consultant calls you back within 30 minutes.
Adyar hosts IT services firms, coaching institutes, banks and premium retail along Lattice Bridge Road, Sardar Patel Road and Gandhi Nagar. Software exporters and freelance consultants billing overseas clients need a fresh LUT in RFD-11 every financial year to invoice without IGST, and many first encounter GST only when foreign receipts cross the Rs.20 lakh services threshold. From a first registration to the annual return, the full range of GSTR-1 & GSTR-3B Monthly Filing is available to Adyar businesses without stepping far from the shop or office — documents travel over WhatsApp, and our Chennai premises are open to anyone who prefers a face-to-face discussion. We serve Besant Nagar and Thiruvanmiyur on the same footing, applying one rule everywhere: reconcile before filing, file before the due date, and keep the client informed at every stage.
Not a bulk-filing portal. A senior consultant knows your file, your jurisdiction and your deadlines.
GSTR-1 requires four-digit HSN reporting for turnover up to Rs.5 crore and six digits above it, and a wrong code often means a wrong rate. We verify the classification of what you actually supply, so your invoices and returns rest on defensible codes.
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.
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.
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 Adyar never leave marketplace deductions unclaimed.
GSTR-3B late fees run at Rs.50 per day and interest at 18 percent per annum on unpaid tax. Our internal cut-offs sit days ahead of statutory due dates precisely so that our clients never hand the department a rupee they did not owe.
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.
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.
With the LUT filed at the start of each financial year and refund claims tracked to credit, exporters supply without blocking funds in IGST and recover accumulated credit on schedule.
Illness, travel or a family function no longer threatens a deadline. With a standing external process holding your calendar and data trail, filings proceed on schedule whether or not you are at your desk.
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.
Excess balances parked in the electronic cash ledger are identified during regular ledger reviews and either utilised against upcoming liability or claimed back as a refund, instead of sitting interest-free with the government.
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.
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.
| Aspect | With ChennaiGST | DIY / Unattended |
|---|---|---|
| Keeping up with changes | Rate changes, portal updates and new thresholds such as the Rs.5 crore e-invoice limit are tracked by us and applied to your case proactively. | Changes are discovered after the fact — often through a rejected filing, a blocked e-way bill or a departmental letter. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
10th Cross Street is a residential street in Adyar, about 1.3 km south-west of the centre of Adyar. The same consultant covers the streets immediately around it — 11th Cross Street (about 50 m); Indira Nagar 2nd Main Road (about 250 m); Indira Nagar 1st Main Road (about 350 m); Indira Nagar 1st Avenue (about 400 m) — so a site visit on 10th Cross Street can usually be combined with other work in Adyar on the same trip. For GST purposes an address on 10th Cross Street falls under the Chennai South CGST Commissionerate, and the Adyar pincode is 600020.

33rd GST Council Meeting, New Delhi — 20 and 24 February 2019 · 2019-02-24
To revive the residential real estate sector, the Council recommended an effective GST rate of five per cent without input tax credit on residential properties outside the affordable segment, and one per cent without input tax credit on affordable housing, with effect from 1 April 2019. The Council reasoned that buyers would get a fair price, that disputes about builders not passing on credit would become irrelevant, and that unutilised credit which used to become a project cost would be removed.
Practical effect: Flat buyers in Chennai pay one or five per cent on under-construction purchases, but the builder cannot claim input credit, so the tax is embedded in the price rather than shown as recoverable.
M/s. New PSP Traders v. Deputy State Tax Officer — Madras High Court (Madurai Bench), W.P.(MD) No. 17026 of 2025, decided 25 June 2025 (C. Saravanan J.) · 2025-06-25
The assessment orders had denied input tax credit purely because the returns were filed after the Section 16(4) cut-off. The Court held that the challenge was squarely covered by newly inserted Section 16(5), which permits credit on invoices relating to the financial years 2017-18 to 2020-21 if taken in any return filed up to 30 November 2021, notwithstanding Section 16(4). The impugned orders were quashed and the matter remitted for fresh orders consistent with the amendment.
How we apply it: A Chennai dealer whose ITC for 2017-18 to 2020-21 was disallowed only for late filing should apply for rectification or move the High Court, since Section 16(5) now protects that credit.
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.
