Question 1

How long does e-invoice setup take in Kundrathur?

Accepted Answer

1-2 working days. 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

What is the process for e-invoice setup?

Accepted Answer

The process runs in clear stages: Applicability check; IRP registration; Software configuration; Testing and training. 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.

Question 3

How do I register on the Invoice Registration Portal and set up e-invoicing?

Accepted Answer

Registration is done on the e-invoice portal einvoice1.gst.gov.in using your GSTIN; the system verifies you through an OTP sent to your GST-registered mobile and email, after which you create IRP login credentials. Businesses already registered on the e-way bill portal can use the same credentials. You then choose how invoices will be reported: direct portal entry, the free offline utility, or API integration through your accounting software such as Tally or a GSP. ChennaiGST handles the complete setup including software configuration and staff training for businesses in Kundrathur for Rs.1,999; call +91 - 9600 606 444 to schedule it.

Question 4

What exactly are the IRN and QR code on an e-invoice?

Accepted Answer

When you report an invoice to the Invoice Registration Portal, it validates the data and returns a unique 64-character Invoice Reference Number, which is a hash generated from your GSTIN, the document number and the financial year, along with a digitally signed QR code. The QR code embeds key details such as both GSTINs, invoice number and date, taxable value and the IRN, allowing anyone to verify the invoice offline. A B2B invoice issued by a mandated taxpayer without an IRN is not a valid tax invoice, and the printed copy must carry the QR code.

Question 5

How many copies of an invoice must I prepare, and is a physical signature compulsory?

Accepted Answer

For goods, the invoice is prepared in triplicate: original for the recipient, duplicate for the transporter and triplicate for the supplier. For services, duplicate suffices: original for the recipient and duplicate for the supplier. On signatures, Rule 46 accepts either a physical signature or a digital signature of the authorised person, and no signature at all is required where the invoice is issued electronically in accordance with the Information Technology Act, which covers e-invoices carrying an IRN and system-generated invoices meeting those conditions. Businesses in Kundrathur moving to paperless billing can therefore drop the ink signature once their process qualifies; call +91 - 9600 606 444 to confirm your setup.

Question 6

Are any businesses exempt from e-invoicing even above Rs.5 crore turnover?

Accepted Answer

Yes. CBIC has exempted certain categories irrespective of turnover: banks, insurers and other financial institutions including NBFCs, goods transport agencies transporting goods by road, suppliers of passenger transportation services, admission to cinema exhibitions in multiplexes, SEZ units, and government departments and local authorities. Note that SEZ developers are covered by the mandate even though SEZ units are exempt. If you fall in an exempt category you should still verify vendor e-invoices you receive, because your ITC depends on their compliance. When in doubt about applicability, call +91 - 9600 606 444 for a quick assessment of your registrations.

Question 7

Is there a deadline for uploading invoices to the IRP after issuing them?

Accepted Answer

For taxpayers with aggregate annual turnover of Rs.10 crore and above, the IRP rejects invoices reported more than thirty days after the invoice date; this thirty-day window applies from 1 April 2025 and covers invoices as well as credit and debit notes. Smaller mandated taxpayers currently have no system-enforced limit, but best practice is to generate the IRN at the time of invoicing itself, since a B2B invoice without an IRN is not valid at all. Real-time generation through your accounting software removes this risk entirely, which is why integrated setup matters.

Question 8

Is e-invoicing compulsory for my business, and at what turnover?

Accepted Answer

E-invoicing is mandatory for registered businesses whose aggregate turnover has exceeded Rs.5 crore in any financial year from 2017-18 onwards, for their B2B supplies and exports. The Rs.5 crore limit applies from 1 August 2023. Once you cross the threshold in any year, the mandate applies from the start of the next financial year and continues permanently, even if turnover later falls. Note that turnover is computed PAN-wide across all GSTINs, not branch-wise. If your books show you crossing Rs.5 crore this year, plan the IRP setup in advance rather than scrambling in April.

Question 9

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 Kundrathur can assess it the same day.

Question 10

What is a debit note under GST and when do I issue one?

Accepted Answer

You issue a debit note when the taxable value or tax charged in the original invoice was less than what is actually payable, for example a price escalation clause kicking in or a rate charged short. Declaring the debit note in GSTR-1 increases your output liability, payable with interest where the shortfall relates to an earlier period. There is no outer time limit on issuing a debit note itself. For your buyer, the debit note is a credit document: following the amendment to Section 16(4), the buyer's time limit to claim ITC runs from the date of the debit note, not the original invoice.

Question 11

How does a used car dealer in Kundrathur pay GST when reselling vehicles?

Accepted Answer

A registered dealer buying and reselling used vehicles pays GST under the margin scheme on the difference between the selling price and the purchase price, with no tax payable where the margin is negative. Following the 55th GST Council's decision, notified in January 2025, the rate on this margin is a uniform 18% for all old and used vehicles, including electric vehicles, replacing the earlier split rates. Purchases from individual sellers attract no GST, and no input credit is involved in the chain. Keep vehicle-wise purchase and sale records, because the margin must be demonstrable car by car. Call +91 - 9600 606 444 for the working format.

Question 12

Something is malfunctioning on the GST portal. How do I raise a formal grievance ticket?

Accepted Answer

Use the GST Self-Service Grievance Redressal Portal at selfservice.gstsystem.in. Select Report Issue, type a keyword describing the problem, and the system suggests the matching category along with FAQs; if those do not resolve it, proceed to raise the ticket by entering your GSTIN or ARN, contact details and a description, and attach screenshots of the error. A ticket reference number is issued instantly by email and SMS. Raising a ticket also creates a record that the failure was on the system side, which helps later if a deadline was missed because of a portal outage. Our Kundrathur office logs tickets for clients as part of retainer support.

Question 13

What are the most common mistakes Chennai businesses make with GST refunds and ITC?

Accepted Answer

The recurring ones we see across Kundrathur are: missing the two-year limitation for RFD-01, mismatches between GSTR-1, GSTR-3B and shipping bill data that stall export refunds, forgetting the April LUT renewal, claiming ITC on invoices absent from GSTR-2B, ignoring blocked credits under Section 17(5), breaching the 180-day supplier payment rule, and treating deficiency memos as rejections instead of refiling within limitation. Each of these is preventable with a simple monthly checklist and a year-end reconciliation. ChennaiGST builds exactly this discipline into its retainer engagements; call +91 - 9600 606 444 if any of these sounds familiar.

Question 14

Can one invoice contain items taxed at different GST rates?

Accepted Answer

Yes, there is no requirement to issue separate invoices per rate. A single tax invoice can carry multiple line items, each with its own HSN code, taxable value, rate and tax amount, and the totals section simply aggregates the tax rate-wise. A hardware store in Kundrathur can bill cement at 18 percent and certain tools at 5 percent on one document. What matters is that each line is classified and taxed correctly, and that mixed baskets are not collapsed into one rate. Be careful with genuine composite supplies, where one principal supply drives a single rate; that is a classification question, not an invoicing one.

Question 15

How does GST work on lorry freight paid to a goods transport agency?

Accepted Answer

A goods transport agency, identified by its issue of a consignment note, is taxed in one of two ways. By default, specified recipients such as companies and registered persons pay 5 percent under reverse charge on the freight and can claim it as ITC. Alternatively, the GTA may opt to pay tax itself under forward charge, at 5 percent without ITC or 18 percent with ITC after the September 2025 rate rationalisation replaced the earlier 12 percent option, by filing the prescribed declaration for the financial year; the invoice should state this option. Transport by an individual lorry owner without a consignment note is not a GTA service and is exempt. Check each transporter's invoice wording before deciding who pays the tax.

Question 16

Is GST payable under reverse charge on payments made to our company directors?

Accepted Answer

It depends on the capacity in which the director is paid. CBIC Circular 140/10/2020 settles the position: remuneration to a whole-time or executive director who is an employee, paid as salary with TDS under Section 192, is outside GST entirely as an employer-employee transaction. In contrast, sitting fees, commission and professional charges paid to independent or non-executive directors, typically suffering TDS under Section 194J, are taxable and the company pays 18 percent under reverse charge, claiming ITC. Companies in Kundrathur should split their director payments ledger accordingly, issue self-invoices for the RCM portion, and keep board resolutions and TDS treatment consistent as supporting evidence.

Question 17

My footwear shop sells chappals at Rs.300 and shoes at Rs.4,000 on the same bill. How do I invoice this?

Accepted Answer

One invoice can comfortably carry both rates. Each pair is tested against the Rs.2,500 sale-value threshold independently, so the chappals are billed at 5% and the Rs.4,000 shoes at 18%, as separate line items under their footwear HSN codes in Chapter 64. Your GSTR-1 HSN summary will then show turnover split across the two rates. Ensure the billing software picks the rate from the item price automatically rather than from a fixed product master, because the same article sold at different price points can legitimately fall in different slabs. A quick POS configuration check prevents months of wrong-rate billing; call +91 - 9600 606 444 to arrange one.

Question 18

I deposited money under the wrong head in my GST cash ledger. Why can the amount not be used?

Accepted Answer

The cash ledger is divided into major heads, IGST, CGST, SGST and cess, and minor heads, tax, interest, penalty, fee and others. An amount deposited under one combination, say CGST-penalty, cannot be directly used to pay under another, say IGST-tax, which is why your balance appears unusable despite money lying in the ledger. The remedy is Form PMT-09, which transfers the amount to the correct head instantly without any officer approval. Many Kundrathur taxpayers wrongly deposit a fresh challan in this situation; a two-minute PMT-09 filing saves that duplication. Call +91 - 9600 606 444 if your ledger looks stuck.

Question 19

Are there any hidden charges for e-invoice setup?

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

Which GST office handles Kundrathur businesses?

Accepted Answer

Businesses in Kundrathur (PIN 600069) 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

Aspect	With ChennaiGST	DIY / Unattended
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.
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.
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.
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.
