Question 1

How long does GSTR-1 & GSTR-3B monthly filing take in Tambaram?

Accepted Answer

Filed before the 11th and 20th of every month. That assumes your documents are complete and there is no departmental query. We start the same day we receive your papers and tell you the realistic completion date upfront rather than an optimistic one. Where the GST portal or the officer causes delay — clarifications, physical verification or system issues — we track it daily and keep you informed on WhatsApp.

Question 2

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 3

A client paid me an advance. Do I raise an invoice or something else?

Accepted Answer

On receiving an advance, you issue a receipt voucher under Rule 50, not an invoice; the tax invoice follows when the service is actually supplied. GST is payable on advances received for services in the period of receipt, and the receipt voucher documents that liability. Advances for the supply of goods are not taxed at receipt for normal taxpayers under Notification 66/2017. If the rate is not determinable when the advance arrives, tax is paid at 18 percent, and if the nature of supply is not determinable, it is treated as inter-state. Service firms in Tambaram with retainer billing should map this into their monthly cycle.

Question 4

What is a B2C large invoice and what is the current threshold?

Accepted Answer

A B2C large invoice is an inter-state supply to an unregistered person exceeding the notified value threshold, which was reduced from Rs.2.5 lakh to Rs.1 lakh. Such invoices must be reported individually in Table 5 of GSTR-1 with the place of supply, instead of being merged into the consolidated B2C summary. The rule helps states track high-value consumer sales flowing across borders. If your Tambaram showroom occasionally bills an unregistered customer from another state above Rs.1 lakh, your billing and returns process must flag it for invoice-wise reporting, or GSTR-1 validations and later scrutiny will surface the gap.

Question 5

I made a mistake in GSTR-3B. Can I revise it?

Accepted Answer

No, GSTR-3B cannot be revised once filed. The GST law allows corrections only through adjustments in the returns of subsequent tax periods. If you under-reported tax, pay the difference with 18 percent interest in the next GSTR-3B or through Form DRC-03. If you over-reported, adjust it in a later month within the time limits allowed. Errors in GSTR-1 can be amended in the following period's return. Because corrections have deadlines, it is best to have the error reviewed quickly; our team in Tambaram can assess it the same day.

Question 6

I generate e-invoices. Do I still have to prepare GSTR-1 separately?

Accepted Answer

If your aggregate turnover exceeds Rs.5 crore, e-invoicing is mandatory and the invoice details reported to the Invoice Registration Portal auto-populate into your GSTR-1. However, auto-population is not a substitute for review. B2C sales, exports without IRN issues, credit notes, amendments and advances still need to be verified or added manually before submission. We review the auto-drafted GSTR-1 against your books each month so that what is filed matches your accounts exactly. If you have just crossed the Rs.5 crore threshold, call +91 - 9600 606 444 and we will set up e-invoicing correctly.

Question 7

My landlord in Tambaram has no GSTIN but my business is registered. Who pays GST on the shop rent?

Accepted Answer

You do. With effect from 10 October 2024, renting of immovable property other than a residential dwelling by an unregistered person to a registered person was brought under reverse charge through Notification 09/2024-Central Tax (Rate). So a registered trader renting a shop from an unregistered landlord must pay 18 percent under RCM through GSTR-3B and can claim it back as input tax credit if eligible. Composition taxpayers have since been kept outside this entry, given they cannot claim credit. Many small businesses in Tambaram are still unaware of this 2024 change, and scrutiny notices on rent entries have already begun appearing. Call +91 - 9600 606 444 to regularise past months.

Question 8

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 9

What is the late fee for filing GSTR-9 after the due date?

Accepted Answer

From FY 2022-23 onwards, the late fee is turnover-linked. For turnover up to Rs.5 crore it is Rs.50 per day (Rs.25 CGST plus Rs.25 SGST) capped at 0.04 percent of turnover; for turnover between Rs.5 crore and Rs.20 crore it is Rs.100 per day with the same cap; and above Rs.20 crore it is Rs.200 per day capped at 0.5 percent of turnover. The fee accrues until the date of filing, so delays get expensive for larger businesses. Filing before 31 December avoids the entire cost.

Question 10

What is the 180-day payment rule for input tax credit?

Accepted Answer

Under the second proviso to Section 16(2) read with Rule 37, if you do not pay your supplier the invoice value including tax within 180 days from the invoice date, you must reverse the proportionate ITC in GSTR-3B, along with interest at 18 percent per annum from the date of availment. The credit can be re-availed, without any time limit, once payment is actually made. Long credit periods negotiated with vendors around Tambaram frequently breach this rule unnoticed, so your reconciliation should include an ageing of creditors mapped to ITC claimed. Call +91 - 9600 606 444 if you need this ageing built into your monthly process.

Question 11

My supplier issued a credit note against an earlier invoice. What must I do with the ITC?

Accepted Answer

When a supplier issues a credit note reducing the taxable value or tax, you must correspondingly reverse the proportionate ITC you had claimed on the original invoice, since the supplier's output liability reduces only when your credit reduces. The credit note flows into your GSTR-2B as a negative entry, and your GSTR-3B claim should net it off in the same period. With the Invoice Management System introduced on the portal from October 2024, you can accept, reject or keep pending supplier documents, and your action on a credit note directly shapes your GSTR-2B. Reconcile purchase returns, rate differences and discount credit notes monthly so reversals never lag behind.

Question 12

Can I reduce GST for discounts given after the sale, like turnover incentives?

Accepted Answer

Only if three conditions in Section 15(3)(b) are met: the discount was established under an agreement that existed before or at the time of supply, it can be linked to specific invoices, and the recipient reverses the input tax credit attributable to it. If all three hold, you issue a GST credit note and reduce your output tax. If any condition fails, which is common for year-end volume incentives negotiated later, the adjustment must go through a commercial credit note without any GST effect. Distributor incentive schemes run from Tambaram should be papered before the season starts, not after.

Question 13

Why is there GST on an under-construction flat but not on a ready-to-move one?

Accepted Answer

Construction of an apartment intended for sale is a supply of service only when any part of the consideration is received before the completion certificate is issued or before first occupation. Such under-construction sales attract 1 percent for affordable residential apartments and 5 percent for other residential apartments, both without input tax credit to the builder. Once the completion certificate is issued, sale of the building is neither a supply of goods nor of services under Schedule III, so a ready-to-move flat carries no GST at all, only stamp duty and registration charges. Timing of booking therefore changes the buyer's cost materially.

Question 14

Which everyday goods now attract 5 percent GST?

Accepted Answer

The 5 percent slab now covers most household essentials that earlier fell in the 12 or 18 percent brackets: soaps, shampoos, toothpaste and toothbrushes, hair oil, bicycles, kitchen utensils and tableware. Packaged foods such as butter, ghee, cheese, namkeens, sauces, pasta, biscuits and chocolates are also at 5 percent, as are most medicines, medical devices and agricultural machinery. Apparel and footwear priced up to Rs.2,500 per piece attract 5 percent as well. Retailers in Tambaram should update billing software rate masters item by item rather than assuming old rates continue.

Question 15

My customer in Mumbai asked me to deliver goods directly to his buyer in Tambaram. How do I bill this?

Accepted Answer

This is a bill-to ship-to transaction under Section 10(1)(b). When goods are delivered to a third party on the instruction of your customer, the law deems your customer's principal place of business as the place of supply, not the actual delivery point. So you invoice the Mumbai customer with IGST even though the goods physically moved within Tamil Nadu, and the Mumbai customer raises a second invoice on the ultimate recipient in Tambaram. Only one e-way bill is needed for the movement, generated by either party with both invoice legs captured. Wrongly billing the delivery-point state is a classic error that misplaces the credit chain entirely.

Question 16

Is there really a penalty for not displaying my GST number at my shop?

Accepted Answer

Yes. Rule 18 of the CGST Rules requires every registered person to display the registration certificate in a prominent location at the principal place of business and every additional place, and to display the GSTIN on the name board at the entry of each such premises. There is no separate penalty provision for this lapse, so officers invoke the general penalty under Section 125, which can extend to Rs.25,000 under CGST with a matching state penalty. Inspection teams visiting Tambaram markets routinely check name boards first, so a few hundred rupees of signage is the cheapest compliance in the entire GST law.

Question 17

My GST status shows suspended. What does that mean for my business in Tambaram?

Accepted Answer

Suspension is an intermediate state that occurs when you apply for cancellation, or when the officer initiates cancellation proceedings, commonly for return defaults or data mismatches. While suspended, you cannot make taxable supplies, meaning you should not issue tax invoices or charge GST, and e-way bill generation is blocked. The fix depends on the cause: if you triggered it by applying for cancellation, await the order; if the department triggered it, reply to the show cause notice in REG-18 within seven working days and clear pending returns. Acting within the notice window usually gets the suspension lifted; call +91 - 9600 606 444 if you have received one.

Question 18

What is the place of supply for freight and courier charges on goods?

Accepted Answer

For transportation of goods, including by courier, Section 12(8) fixes the place of supply as the location of the recipient where the recipient is registered. Where the recipient is unregistered, it is the location where the goods are handed over for transportation. So a registered Tambaram manufacturer paying a transporter for a Chennai-to-Delhi movement has Tamil Nadu as the place of supply, and the RCM liability is paid as CGST plus SGST if the transporter is also in Tamil Nadu. This rule matters chiefly for paying reverse charge on GTA freight under the correct heads, because paying IGST where CGST and SGST were due creates a refund-and-repay exercise later.

Question 19

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

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 20

Which GST office handles Tambaram businesses?

Accepted Answer

Businesses in Tambaram (PIN 600045) generally fall under the CGST Chennai Outer 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 21

Can I get GSTR-1 & GSTR-3B monthly filing done online without visiting the office?

Accepted Answer

Yes, the entire process can be handled online. You share scanned documents on WhatsApp or email, we prepare and file everything on the GST portal, and you receive the acknowledgement and filed copies digitally. Businesses in Tambaram regularly complete monthly returns with us without a single office visit. If a physical verification or personal hearing is required by the department, we guide you through it.

Aspect	With ChennaiGST	DIY / Unattended
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.
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.
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.
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.
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.
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.
