Question 1

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 2

Do you provide gst return filing for small businesses and proprietorships in KK Nagar?

Accepted Answer

Yes. A large share of our clients in KK Nagar are proprietors, small traders, shop owners, freelancers and family businesses rather than large companies. The fee of Rs.749/month 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 3

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 KK Nagar 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 4

How are B2B and B2C invoices reported differently in GST returns?

Accepted Answer

B2B invoices, meaning supplies to registered buyers, are reported invoice by invoice in Table 4 of GSTR-1 with the buyer's GSTIN, so each one flows into that buyer's GSTR-2B for credit. B2C supplies are split into two streams: large inter-state invoices above the threshold are reported invoice-wise in Table 5, while all remaining B2C sales are reported as consolidated, rate-wise totals per state in Table 7. This is why capturing the buyer's GSTIN correctly at billing matters so much; an invoice keyed as B2C by a cashier gives the registered buyer no credit and triggers correction requests later.

Question 5

My company has taken a residential flat on rent. Why is our accountant paying GST on it?

Accepted Answer

Because of a reverse charge entry effective 18 July 2022: renting of a residential dwelling to a registered person attracts 18 percent GST payable by the tenant under reverse charge, even when the landlord is unregistered. Renting to unregistered individuals for residence remains fully exempt. There is a carve-out from 1 January 2023: a proprietor renting a dwelling in his personal capacity for use as his own residence, on his own account and not for the business, is exempt. Companies and firms renting flats, including for guest houses, must therefore pay RCM monthly through GSTR-3B. We correct many such missed entries during our compliance health checks.

Question 6

Why is the portal not letting me file GSTR-1?

Accepted Answer

Under Rule 59(6) of the CGST Rules, the portal blocks GSTR-1 filing if the GSTR-3B of the preceding tax period has not been filed. GST returns are sequential, so a single skipped GSTR-3B stops the entire chain. The fix is to file the pending GSTR-3B along with its late fee and interest, after which GSTR-1 opens up again. If you are unsure which period is pending, we can check your dashboard and clear the sequence for you the same day from our office near KK Nagar.

Question 7

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 8

My SaaS startup in KK Nagar bills both US and Indian customers. Is everything zero-rated?

Accepted Answer

No. Only the supplies satisfying the export conditions are zero-rated under your LUT. Subscriptions billed to customers located in India are ordinary taxable supplies at 18 percent, with the place of supply being the registered customer's location, or the address on record for unregistered users. Your GSTR-1 must therefore separate export invoices from domestic B2B and B2C supplies, and your accumulated ITC refund is computed only in proportion to export turnover. Many KK Nagar SaaS founders wrongly treat all revenue as export because billing runs through one gateway; a revenue-wise mapping avoids demands later. Call +91 - 9600 606 444 for a review.

Question 9

Can I revise GSTR-9 after filing if I find an error?

Accepted Answer

No, GSTR-9 cannot be revised once filed. This makes pre-filing reconciliation critical, because the annual return is the department's primary reference during scrutiny and audit. If you discover unpaid liability after filing, it can be paid voluntarily through Form DRC-03 with interest, which mitigates penalty exposure. If credit was short-claimed, the annual return itself cannot fix it, since input tax credit claims are governed by the time limits in Section 16(4). Our process in KK Nagar involves a line-by-line reconciliation and a client sign-off before we submit anything.

Question 10

How and when can I opt in or out of the QRMP scheme?

Accepted Answer

The option is exercised on the GST portal under Services, Returns, Opt-in for Quarterly Return. The window for any quarter runs from the first day of the second month of the preceding quarter to the last day of the first month of the quarter you are opting for. For example, to be under QRMP for July to September, opt in between 1 May and 31 July. Once chosen, the option continues for future quarters until you change it or your turnover crosses Rs.5 crore. We handle the opt-in for clients at no extra charge.

Question 11

What counts as exempt supply when calculating my ITC reversal ratio?

Accepted Answer

Exempt supplies for Rules 42 and 43 include nil-rated and wholly exempted supplies, and by virtue of Section 17(3) also cover outward supplies on which your recipient pays tax under reverse charge, transactions in securities valued at one percent of sale value, and sale of land or completed buildings valued at stamp duty value. Importantly, interest earned on deposits, loans or advances is excluded from the exempt turnover for this computation for everyone except banking companies and financial institutions. Many businesses in KK Nagar inflate their reversal by wrongly including fixed deposit interest, handing over credit the law never asked them to reverse.

Question 12

Do I have to issue an invoice for every small cash sale in my shop?

Accepted Answer

Not necessarily. Where the value of a supply is less than Rs.200, the buyer is unregistered, and the buyer does not ask for an invoice, you may skip issuing an individual tax invoice. Instead, you must prepare one consolidated tax invoice at the close of each day covering all such small sales. The moment a customer demands an invoice, or the sale is Rs.200 or more, a proper invoice is required. Retail counters typically issue system receipts to every customer anyway, which is cleaner practice, but the daily consolidated invoice is the legal minimum for petty sales.

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

Can you give me a simple GST due-date calendar for my business?

Accepted Answer

For monthly filers: GSTR-1 by the 11th and GSTR-3B by the 20th of the next month. Under QRMP: optional IFF by the 13th of the next month, PMT-06 payment by the 25th, quarterly GSTR-1 by the 13th and GSTR-3B by the 22nd (Tamil Nadu) after the quarter. Composition dealers pay via CMP-08 by the 18th after each quarter and file GSTR-4 annually by 30 June. GSTR-7 and GSTR-8 are due on the 10th, and GSTR-9 and GSTR-9C by 31 December. Clients in KK Nagar receive our reminder messages before every date.

Question 15

What is the difference between a GST credit note and a commercial credit note?

Accepted Answer

A GST credit note is issued under Section 34, is reported in GSTR-1, and reduces your output tax, with the buyer reversing equivalent input credit. A commercial or financial credit note adjusts only the money owed between the parties; it carries no GST, is not reported in returns, and leaves everyone's tax position untouched. Businesses use commercial credit notes when the 30 November deadline has passed, or for post-supply discounts that do not satisfy the statutory conditions for a tax adjustment. Choosing the wrong instrument is a frequent audit finding, so decide the type before the note is issued.

Question 16

How do I round off tax amounts on a GST invoice?

Accepted Answer

Section 170 of the CGST Act prescribes normal rounding to the nearest rupee: where the tax contains a part of a rupee, fifty paise or more is rounded up to one rupee, and less than fifty paise is ignored. The rounding is applied to the tax amount on each invoice, separately for each tax head, so CGST and SGST are each rounded individually rather than rounding only the invoice total. Most billing software handles this automatically, but spreadsheets and manual bills often round the grand total instead, creating one-rupee mismatches that clutter reconciliations across thousands of invoices.

Question 17

What is the difference between ISD and cross-charge, and when is each used?

Accepted Answer

They solve different problems. The Input Service Distributor mechanism distributes credit on third-party input services received at the head office but consumed by branches, such as an audit fee or software licence billed centrally; the ISD passes the credit itself through ISD invoices and GSTR-6, without charging tax again. Cross-charge applies where the head office performs a service for branches using its own resources; here the head office makes an outward supply, issues a tax invoice with tax, and the branch claims ITC. With ISD distribution mandatory for common third-party input services from 1 April 2025, businesses must now run both mechanisms side by side, each for its correct category.

Question 18

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 KK Nagar should be papered before the season starts, not after.

Question 19

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

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 20

Which GST office handles KK Nagar businesses?

Accepted Answer

Businesses in KK Nagar (PIN 600078) 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 21

How much does GSTR-1 & GSTR-3B monthly filing cost in KK Nagar?

Accepted Answer

Our fee for GSTR-1 & GSTR-3B monthly filing in KK Nagar starts at Rs.749/month 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.

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.
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.
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.
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.
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.
