Question 1

Which GST office handles Kodambakkam businesses?

Accepted Answer

Businesses in Kodambakkam (PIN 600024) generally fall under the CGST Chennai South Commissionerate, with state-jurisdiction cases handled by the Tamil Nadu Commercial Taxes Department. Your exact division and range can be confirmed from your GSTIN on the GST portal. We regularly appear before this jurisdiction for registrations, clarifications and hearings, so we know the local practice and documentation preferences.

Question 2

What documents are required for GSTR-1 & GSTR-3B monthly filing in Kodambakkam?

Accepted Answer

For GSTR-1 & GSTR-3B monthly filing you will generally need: Sales invoices or sales register for the month, Purchase invoices or purchase register, Credit notes and debit notes issued during the month, GST portal login credentials, Bank statement for the period, if reconciliation is needed. The exact list depends on your constitution — proprietorship, partnership, LLP or company — and on the specifics of your case. Send what you have on WhatsApp to +91 - 9600 606 444 and we will confirm within the same working day exactly what else is needed, so nothing is rejected later for a missing paper.

Question 3

What is the difference between CPIN and CIN, and how long is a GST challan valid?

Accepted Answer

When you generate a challan in Form PMT-06 on the portal, the system issues a fourteen-digit Common Portal Identification Number, the CPIN, which identifies the unpaid challan and remains valid for fifteen days. Once the bank receives your payment, a seventeen-digit Challan Identification Number, the CIN, is generated, comprising the CPIN plus the bank code, and the amount credits your electronic cash ledger. If a challan expires unpaid, simply generate a fresh one; no consequence follows. Payment modes include net banking, UPI, cards, NEFT or RTGS, and over-the-counter deposit up to Rs.10,000 per challan per tax period.

Question 4

What is GSTR-2B and why does my consultant match it before filing?

Accepted Answer

GSTR-2B is an auto-drafted statement of the input tax credit available to you, generated on the 14th of every month from the GSTR-1 and IFF filings of your suppliers. Input tax credit in GSTR-3B can only be claimed for invoices appearing in GSTR-2B, so matching your purchase register against it before filing is essential. If a supplier has not uploaded an invoice, the credit must be deferred and the supplier followed up. This monthly reconciliation is included in our return filing service for businesses in Kodambakkam.

Question 5

My bank account was debited for a GST challan but the cash ledger shows nothing. What do I do?

Accepted Answer

This is a payment-communication failure between the bank and the portal, and the prescribed remedy is Form PMT-07, filed under Services, then Payments, then Grievance against Payment. Quote the CPIN, bank name and debit details; the system takes up the discrepancy with the bank, and the amount either credits your ledger once the bank confirms, or is re-credited to your account if the transaction failed. Do not pay twice immediately; most cases resolve within a day or two. If a return due date is pressing, generate a fresh challan and later seek refund of the duplicate. Kodambakkam clients can call +91 - 9600 606 444 for urgent help.

Question 6

Our institute charges one fee covering classes, study material and hostel. How is it taxed?

Accepted Answer

A single price for naturally bundled components is a composite supply, taxed at the rate of the principal supply. For a coaching institute, coaching is the principal supply, so the entire lump sum, including printed materials and boarding provided as part of the package, attracts 18 percent. Printing separate invoices for books at nil rate out of a bundled fee is a known audit red flag and is routinely rejected. If the institute genuinely sells optional printed books to anyone at a separate price, those standalone sales can take the book's own treatment. Structure the fee schedule deliberately, not after the demand arrives.

Question 7

When can I issue a GST credit note against my sales invoice?

Accepted Answer

Section 34 permits a credit note where the taxable value or tax charged in the invoice exceeds what is actually payable, where the goods are returned by the recipient, or where the goods or services are found deficient. The credit note references the original invoice, and reporting it in your GSTR-1 reduces your output tax liability for that period. It is the correct tool for sales returns, rate errors and quality claims. What a credit note cannot do is cancel an e-invoice after the twenty-four hour IRP window or rewrite history for a different customer; it must trace to a genuine adjustment on an identified invoice.

Question 8

What is the due date for GSTR-3B in Tamil Nadu?

Accepted Answer

For monthly filers, GSTR-3B is due on the 20th of the following month. If you are registered in Tamil Nadu and have opted for the QRMP scheme, your quarterly GSTR-3B is due on the 22nd of the month following the quarter. GSTR-3B is the summary return through which you actually pay tax, so missing it attracts a late fee of Rs.50 per day (Rs.20 for nil returns) plus interest at 18 percent per annum on tax paid late.

Question 9

My supplier has not uploaded an invoice and it is missing from GSTR-2B. Can I still claim the ITC?

Accepted Answer

No, not until it appears. Since 1 January 2022, Section 16(2)(aa) permits ITC only on invoices furnished by the supplier in GSTR-1 and communicated to you in GSTR-2B; the earlier provisional credit tolerance is gone. Claiming credit on a missing invoice invites a Rule 88D intimation and reversal with interest at 18 percent. The practical remedy is vendor follow-up: withhold the tax portion of payment until the supplier uploads, and claim the credit in the month it appears in GSTR-2B, subject to the overall time limit of 30 November following the financial year. Vendor discipline clauses in purchase orders help enormously.

Question 10

Our company spends on CSR activities. Is the GST paid on those purchases creditable?

Accepted Answer

Not any more. Section 17(5)(fa), inserted with effect from 1 October 2023, specifically blocks input tax credit on goods or services used for corporate social responsibility activities under Section 135 of the Companies Act. Before this date the position was contested, with advance rulings going both ways, so credits availed for earlier periods may still be defensible on merits if questioned. For current periods, GST on CSR purchases, whether school furniture donated or medical supplies distributed, is a cost. Companies in Kodambakkam should route CSR procurement through a separate expense code so their monthly reconciliation automatically excludes these invoices from the ITC claim.

Question 11

What is the difference between GSTR-2A and GSTR-2B, and which one should I follow?

Accepted Answer

GSTR-2A is a dynamic statement that keeps changing as suppliers file or amend their returns, so the same month's data can look different on different dates. GSTR-2B is a static statement generated on the 14th of each month, capturing supplier filings between cut-off dates, and it never changes afterwards. The law ties your ITC eligibility to GSTR-2B, and GSTR-3B auto-populates from it, so 2B is the statement to reconcile against for monthly claims. GSTR-2A remains useful for tracing when an invoice was actually uploaded, which helps in replying to departmental queries about earlier periods.

Question 12

Should I claim a refund of my accumulated ITC or just carry it forward?

Accepted Answer

Carry-forward suits businesses whose future output tax will absorb the credit within a few months, since it avoids refund paperwork. A refund makes sense when the credit keeps growing and will never be absorbed, which is typical for exporters under LUT and businesses with inverted duty structure, because idle credit is interest-free money locked with the government. Remember that refunds are only available in categories permitted by Section 54; ordinary accumulated credit from slow sales cannot be refunded. A quick review of your credit ledger trend over six months usually makes the right answer obvious.

Question 13

What is the penalty for running a business without GST registration?

Accepted Answer

A taxable person who is liable to register but fails to do so faces a penalty of Rs.10,000 or the amount of tax evaded, whichever is higher, under Section 122 of the CGST Act. Beyond the penalty, the department can demand the tax for the entire unregistered period with interest at 18 percent per annum, and you cannot recover that tax from customers you billed without GST. Goods moved without registration and e-way bills, required for consignments above Rs.50,000, also risk detention. If your turnover has crossed the threshold, registering within thirty days is far cheaper than regularising later.

Question 14

How do I track the status of a grievance ticket or any ARN I have on the GST portal?

Accepted Answer

For grievance tickets, open selfservice.gstsystem.in and use Check Status by entering the ticket reference number; the screen shows whether it is open, under processing or resolved, with the resolution comments. For applications filed on the main portal, log in and use Services, then Track Application Status, choosing the module and entering the ARN, or open My Applications to see every application with its case detail folder, notices and replies in one place. Diarise every ARN the day it is generated, because reply windows run from portal timestamps. ChennaiGST maintains an ARN tracker for every client engagement.

Question 15

Is GST charged before or after the discount shown on my invoice?

Accepted Answer

Discounts given before or at the time of supply and recorded on the face of the invoice are excluded from the value of supply under Section 15(3)(a). You therefore charge GST on the net amount after discount. For example, a Rs.10,000 item with a 10 percent trade discount shown on the invoice is taxed on Rs.9,000. The condition is documentation: the discount must appear on the invoice itself. Informal reductions settled outside the bill do not reduce taxable value. Retail schemes such as festival discounts and trade margins should always be structured to print on the invoice.

Question 16

Is GST applicable on rent for my shop or office premises?

Accepted Answer

Yes. Renting of commercial property such as shops, offices, godowns and industrial sheds is a taxable supply of services at 18 percent, charged by the landlord under forward charge once the landlord's aggregate turnover, including this rent, crosses Rs.20 lakh. The tenant, if registered and using the premises for business, can claim the GST as input tax credit, since renting is not a blocked credit. Landlords with several small commercial properties often cross the threshold without realising it, because rent from all properties on the same PAN is clubbed. A yearly turnover check protects against retrospective demands.

Question 17

What is the electronic liability register on the GST portal and why should I check it?

Accepted Answer

The electronic liability register, maintained in Form PMT-01, records every liability raised against your GSTIN: self-assessed tax from returns in Part I, and demands from assessments, adjudication orders and DRC-07 summaries in Part II. Payments and pre-deposits are set off against these entries. You can view it under Services, then Ledgers. Checking Part II periodically matters because demand entries you never noticed can trigger recovery, interest accumulation and refund adjustments. During any refund claim, the officer will offset outstanding register balances, so a clean register speeds up your money. We review all three ledgers in every Kodambakkam health check.

Question 18

What is the GST rate on a works contract for a commercial building?

Accepted Answer

Under GST, a works contract relating to immovable property is treated wholly as a supply of services, and the standard rate is 18 percent on the contract value, with the contractor eligible for input tax credit on cement, steel and other inputs. This applies to construction, fabrication, erection, repair and renovation contracts for factories, offices and commercial buildings. The old VAT-plus-service-tax splitting of material and labour is gone; one rate applies to the whole consideration. Contractors should also note that free-issue materials supplied by the client can affect valuation, so contract drafting deserves attention before quoting.

Question 19

Are there any hidden charges for GSTR-1 & GSTR-3B monthly filing?

Accepted Answer

No. The fee quoted before we start is the fee you pay. Government fees, portal charges or statutory late fees, where they apply, are separate and disclosed to you in advance with the exact amount. We issue a proper GST invoice for our professional fee. If the scope of work changes — for example, an unexpected notice or additional periods — we tell you the revised fee before doing anything further.

Question 20

Do you provide GSTR-1 & GSTR-3B monthly filing for businesses on Mamabalam Highway?

Accepted Answer

Yes. We serve businesses on and around Mamabalam Highway in Kodambakkam — shops, offices, godowns and home-run businesses alike. Document pickup can be arranged at your premises, or you can send everything on WhatsApp and complete monthly returns without leaving your counter. Call +91 - 9600 606 444 and mention your location; a consultant will confirm the fee and timeline immediately.

Question 21

What is the process for GSTR-1 & GSTR-3B monthly filing?

Accepted Answer

The process runs in clear stages: Monthly data collection; GSTR-1 preparation and filing; ITC reconciliation with GSTR-2B; Tax computation and confirmation. A senior consultant reviews your file at each stage rather than passing it to a data-entry desk, and you receive a confirmation with the filed documents once it is complete. You always know which stage your work is at — we update you on WhatsApp instead of leaving you to follow up.

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.
Due-date tracking	A maintained compliance calendar with internal cut-offs days before the 11th and the 20th; we chase you for data, not the other way around.	Deadlines remembered from memory or phone alarms; one busy week and the return slips past the due date.
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.
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.
