Question 1

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 2

Which GST office handles Porur businesses?

Accepted Answer

Businesses in Porur (PIN 600116) 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 3

Can I run different invoice series for different branches or types of sales?

Accepted Answer

Yes. The rules expressly permit one or multiple series of invoice numbers, so you can run separate series for each branch, counter or category, for example RET/001 for retail billing and EXP/001 for exports, under the same GSTIN. Each series must independently be consecutive and unique within the financial year, and all series must be reported in the documents table of GSTR-1. For businesses under the e-invoicing mandate, the IRP validates that a document number is not repeated within the year for the GSTIN, so overlapping series will cause IRN rejections. We help Porur businesses design clean series structures; call +91 - 9600 606 444.

Question 4

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 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 Porur 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

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 Porur for Rs.1,999; call +91 - 9600 606 444 to schedule it.

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

What is the penalty if I am covered by e-invoicing but do not generate IRNs?

Accepted Answer

The consequences are serious. An invoice issued without an IRN by a mandated taxpayer is not a valid tax invoice, which exposes you to penalty under Section 122 of Rs.10,000 or the tax due, whichever is higher, per invoice for non-issuance, and Rs.25,000 per invoice for an incorrect invoice. Goods moving on such invoices can be detained, and, most damaging commercially, your B2B customers may lose their input tax credit and will quickly stop buying from you. Large buyers now routinely verify IRNs before releasing payments. If you have crossed Rs.5 crore and have not started, regularise immediately rather than waiting for a notice.

Question 9

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 10

How does a GTA opt for forward charge, and by when must it be done?

Accepted Answer

The option is exercised by filing the Annexure V declaration on the GST portal. For an existing GTA, the window for a financial year runs from 1 January to 31 March of the preceding financial year, so the choice for the coming year must be locked in by 31 March. A newly registered GTA must file the declaration within forty-five days of applying for registration or one month from the date of obtaining registration, whichever is later. Once exercised, the option continues for future years automatically unless the GTA files Annexure VI to revert to reverse charge. Missing the window means remaining under the default reverse charge mechanism for the whole year.

Question 11

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 12

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 Porur health check.

Question 13

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

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 14

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 Porur 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 15

Which goods and services attract the new 40 percent GST rate?

Accepted Answer

The 40 percent rate is confined to luxury and demerit supplies. It covers aerated waters, caffeinated and other sugary carbonated beverages, large cars beyond the small-car specifications, motorcycles above 350cc, yachts, personal aircraft, and specified actionable claims such as betting, casinos and online money gaming. Pan masala and tobacco products continue under their earlier levy structure until the compensation cess obligations are discharged, after which they move to the 40 percent rate as notified. If your business deals in any of these lines, pricing and working capital need careful planning.

Question 16

Which educational services are actually exempt from GST?

Accepted Answer

The exemption is confined to an educational institution as defined, meaning one providing pre-school education, education up to higher secondary school or equivalent, education as part of a curriculum for obtaining a qualification recognised by Indian law, or an approved vocational education course. Services by such institutions to their students, and specified input services to schools such as transport, catering and security, are exempt. Everything outside this boundary is taxable: private tuition, test preparation, hobby classes, skill courses without recognised certification, and training by ed-tech companies. The recognition of the qualification under Indian law is the decisive test, not the subject taught.

Question 17

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 Porur 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 18

Our company paid fees to a lawyer. Who pays the GST on this?

Accepted Answer

You do, as the recipient. Legal services supplied by an individual advocate, a firm of advocates or a senior advocate to a business entity are notified under Section 9(3), so the advocate does not charge GST and your business pays 18 percent under reverse charge in cash through GSTR-3B, claiming it back as ITC if otherwise eligible. Relief exists for small recipients: legal services to a business entity whose turnover is within the registration threshold are exempt. Since the advocate is usually unregistered, remember to raise a self-invoice and payment voucher for the transaction. Litigation-heavy businesses in Porur should reconcile their legal expense ledger against RCM paid every quarter.

Question 19

How much does e-invoice setup cost in Porur?

Accepted Answer

Our fee for e-invoice setup in Porur starts at Rs.1,999 and is quoted in full before we begin — there are no hidden charges added later. The fee covers professional work end to end: document review, preparation, filing and follow-up until completion. Government fees or portal charges, where applicable, are separate and always shown to you upfront. For an exact quote based on your turnover and business type, call +91 - 9600 606 444 and a consultant will confirm it on the call.

Question 20

Do you provide e invoice registration for small businesses and proprietorships in Porur?

Accepted Answer

Yes. A large share of our clients in Porur are proprietors, small traders, shop owners, freelancers and family businesses rather than large companies. The fee of Rs.1,999 and the process are the same regardless of size, and we explain the compliance position in plain language — in Tamil or English — so you understand what is being filed on your behalf and why.

Question 21

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.

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