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

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

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 3

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 4

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 Tiruninravur can assess it the same day.

Question 5

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 6

How does an ISD actually distribute credit among branches?

Accepted Answer

Distribution follows Section 20 read with Rule 39. Credit attributable to a single branch goes only to that branch; credit for common services is distributed among operational branches in the ratio of their turnover in the preceding financial year. The ISD issues an ISD invoice to each recipient GSTIN and reports the distribution in GSTR-6 by the 13th of the following month, after which the credit appears in each branch's GSTR-2B. IGST credit is distributed as IGST, while CGST and SGST credit is distributed as IGST to branches in other states. Excess distribution is recoverable from the recipient with interest, so the turnover ratios must be computed carefully each year.

Question 7

My medical shop also sells supplements, cosmetics and baby products. Do they all take the medicine rate?

Accepted Answer

No, and this is where pharmacies slip. Only items answering the description of drugs and medicaments take 5% or nil. Nutraceuticals and protein supplements generally attract 18%, beauty and makeup preparations 18%, while daily-use items such as soaps, shampoos and toothpaste came down to 5% in September 2025. Each product must be mapped to its own HSN code and rate in your billing software, and your GSTR-1 HSN summary must reflect that mix. A single wrong default rate applied across the counter creates either short payment or overcharging. ChennaiGST runs product-master audits for pharmacies in Tiruninravur; call +91 - 9600 606 444 to schedule one.

Question 8

How exactly do I pay RCM in my return and claim it back as credit?

Accepted Answer

Report the taxable value and tax in Table 3.1(d) of GSTR-3B; this liability must be discharged in cash through the electronic cash ledger, because input tax credit cannot be used to pay reverse charge dues. In the same return, claim the amount as ITC in Table 4(A)(2) or 4(A)(3), so the net impact is usually nil. RCM invoices from registered suppliers like GTAs appear in GSTR-2B, but credit for unregistered-supplier RCM rests on your self-invoice, and Circular 211/5/2024 confirms the Section 16(4) deadline runs from the year of that self-invoice. Businesses in Tiruninravur that skip the 3.1(d) reporting but claim the credit invite automatic mismatch flags.

Question 9

Why is my nil return SMS to 14409 not working?

Accepted Answer

SMS filing fails for a few common reasons. The message must come from the exact mobile number registered against an authorised signatory on the GST portal, the format must match precisely with single spaces, and all returns for earlier periods must already be filed since GST returns are sequential. It also fails if the return is not truly nil, for instance if an amendment or credit note is pending to be reported. If one number is registered for multiple GSTINs, each needs its own SMS. We can diagnose the exact reason and file it online instead.

Question 10

My buyer has not accepted my credit note. Does that affect my tax reduction?

Accepted Answer

Yes. Your output tax reduction on a credit note is conditional on the corresponding input tax credit being reversed by the recipient. On the portal, the Invoice Management System now presents your credit notes to the buyer for action, and a rejected credit note flows back into your liability computation. Practically, this means credit notes need commercial agreement before they are reported, not after. Keep an email trail with the buyer, confirm they will reverse the credit in their GSTR-3B, and reconcile IMS actions monthly. ChennaiGST tracks credit note acceptance for Tiruninravur clients as part of the monthly filing cycle.

Question 11

How do I claim credit of the IGST paid on imported goods?

Accepted Answer

IGST paid at customs on imported goods is fully creditable, with the bill of entry serving as the prescribed duty-paying document instead of a tax invoice. The data flows from ICEGATE into your GSTR-2B, and the claim is made in Table 4(A)(1) of GSTR-3B. If a bill of entry does not appear, use the search BoE facility on the GST portal to fetch the record before assuming it is missing. Remember that basic customs duty and the social welfare surcharge are never creditable; only the IGST and compensation cess components are. Importers in Tiruninravur should reconcile their ICEGATE ledger with GSTR-2B quarterly, because clearance-date mismatches are frequent.

Question 12

How do I decide whether to charge CGST plus SGST or IGST on an invoice?

Accepted Answer

Compare two data points: the location of the supplier and the place of supply determined under the IGST Act. If both fall in the same state, the supply is intra-state and you charge CGST plus SGST; if they fall in different states, it is inter-state and you charge IGST. The buyer's billing address alone is not the test; the place of supply rules for the specific goods or service govern. Common traps include hotel stays, property-linked services and bill-to ship-to chains, where the place of supply departs from the customer's address. Configuring these rules in your billing software saves Tiruninravur businesses repeated corrections; call +91 - 9600 606 444 for a setup review.

Question 13

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 14

What GST rate applies to a goods transport agency: 5 percent or 18 percent?

Accepted Answer

Both exist, depending on the option exercised. The default position is 5 percent payable by the specified recipient under reverse charge, with no input tax credit to the GTA. Alternatively, a GTA may opt to pay tax itself under forward charge, either at 5 percent without input tax credit or at the higher rate with full credit, which was revised from 12 percent to 18 percent with effect from 22 September 2025. The with-credit option suits transporters with large spends on vehicles and tyres. Once the forward charge option is exercised for a year, it applies to all consignments of that year.

Question 15

Our security agency does not charge GST on its bills. Is that correct?

Accepted Answer

Quite possibly, yes. Since 1 January 2019, security services meaning supply of security personnel, when provided by any person other than a body corporate to a registered person, fall under reverse charge, so the agency correctly bills without tax and you pay 18 percent through GSTR-3B in cash, claiming ITC. If your security agency is a private limited company, however, RCM does not apply and it must charge GST on its invoice under forward charge. Composition taxpayers as recipients are excluded from this entry. Confirm the agency's constitution from its PAN, because paying under the wrong mechanism creates trouble for both sides.

Question 16

Our head office in Tiruninravur supports branches in other states. Is a cross-charge invoice really required?

Accepted Answer

Yes. Branches with separate GSTINs are distinct persons, and Schedule I treats supplies between them as taxable even without consideration. Services your head office renders to branches, such as accounting, IT support or management oversight, should be cross-charged through a tax invoice with IGST, which the branch claims as credit. On valuation, Rule 28 helps: where the recipient branch is entitled to full ITC, the value declared on the invoice is deemed to be the open market value, and Circular 199/11/2023 clarifies that internally generated services need not include the salary cost of head office employees. A documented cross-charge policy keeps audits short; call +91 - 9600 606 444 to set one up.

Question 17

How much time do I get to raise an invoice for services?

Accepted Answer

A tax invoice for services must be issued within thirty days from the date of supply of the service. For banks, insurers, financial institutions and NBFCs, the limit is forty-five days. Where services are supplied continuously, the invoice follows the contract: if the due date of payment is ascertainable, invoice on or before that date; if not, invoice when payment is received; and if payment is linked to completion of an event or milestone, invoice on or before its completion. Consultants and agencies that bill quarterly should check their contracts against these rules, since late invoicing defers nothing legally.

Question 18

By when must I issue a tax invoice when I sell goods?

Accepted Answer

For goods, Section 31 requires the tax invoice to be issued before or at the time of removal of the goods, where the supply involves movement, or before or at the time of delivery or making the goods available in other cases. In simple terms, the invoice must travel with the goods; a lorry leaving your Tiruninravur godown without an invoice is exposed to detention even if the e-way bill exists. For continuous supplies of goods with successive statements or payments, the invoice must be issued when each statement is issued or each payment is received.

Question 19

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.

Question 20

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

Accepted Answer

Yes. A large share of our clients in Tiruninravur 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 21

Which GST office handles Tiruninravur businesses?

Accepted Answer

Businesses in Tiruninravur (PIN 602024) 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.

Aspect	With ChennaiGST	DIY / Unattended
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.
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.
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.
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.
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.
