Question 1

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

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 2

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 3

My workshop bills customers for spare parts and labour together. How should GST be charged?

Accepted Answer

The accepted practice, supported by CBIC's clarification on servicing, is that where the invoice separately shows the value of parts and the value of labour, each takes its own treatment: parts as a supply of goods and repair labour as a service at 18%. Since auto components also moved to 18% from September 2025, both lines of a typical job card now carry the same rate, which removes the old temptation to shift value between parts and labour. Still keep the split, because HSN and SAC reporting in GSTR-1 differ for goods and services. Workshops can call +91 - 9600 606 444 for invoice-format templates.

Question 4

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 5

Is there a late fee for filing GSTR-1 after the 11th?

Accepted Answer

Yes. Late fee for GSTR-1 is Rs.50 per day of delay, and Rs.20 per day where there are no outward supplies, subject to caps linked to your turnover. Although the portal historically collected GSTR-1 late fees through the next GSTR-3B, the liability arises the moment the due date passes. Delayed GSTR-1 also hurts your customers, because your invoices miss their GSTR-2B and their input tax credit gets deferred, which can strain business relationships. Filing by the 11th every month avoids both the cost and the friction.

Question 6

What is GSTR-2B and why does my consultant match it before filing?

Accepted Answer

GSTR-2B is an auto-drafted statement of the input tax credit available to you, generated on the 14th of every month from the GSTR-1 and IFF filings of your suppliers. Input tax credit in GSTR-3B can only be claimed for invoices appearing in GSTR-2B, so matching your purchase register against it before filing is essential. If a supplier has not uploaded an invoice, the credit must be deferred and the supplier followed up. This monthly reconciliation is included in our return filing service for businesses in Madambakkam.

Question 7

Can I issue a single credit note against several invoices?

Accepted Answer

Yes. Since the amendment to Section 34 by the CGST (Amendment) Act, 2018, effective 1 February 2019, the law permits one or more credit notes to be issued against one or more tax invoices of a financial year. A distributor giving a season-end adjustment to a retailer can therefore issue one consolidated credit note covering dozens of invoices, rather than one note per bill. When reporting it in GSTR-1, the portal accepts credit notes without invoice-wise linking for this reason. Maintain a working annexed to the credit note listing the invoices covered, because in scrutiny the officer will ask you to establish the linkage and the arithmetic.

Question 8

Do I have to report HSN codes in my GSTR-1?

Accepted Answer

Yes. Taxpayers with aggregate turnover up to Rs.5 crore must report a 4-digit HSN summary for B2B supplies in Table 12 of GSTR-1, while those above Rs.5 crore must report 6-digit HSN codes for all supplies. The portal now validates HSN entries against its master list, so wrong or truncated codes can block filing. Getting HSN classification right also determines your tax rate, so it is worth a one-time review of your product list. Our team in Madambakkam maintains a verified HSN master for every client.

Question 9

I am selling old machinery on which ITC was claimed. Do I have to pay anything back?

Accepted Answer

Yes. Under Section 18(6) read with Rule 44, on supply of capital goods on which credit was taken, you must pay the higher of two amounts: the ITC originally availed reduced by five percent per quarter or part thereof from the invoice date, or the tax on the transaction value of the sale. For example, machinery held for three full years has its credit reduced by sixty percent, and you compare the remaining forty percent with the actual tax on the sale price. Refractory bricks, moulds, dies, jigs and fixtures sold as scrap need tax only on transaction value. Compute both figures before invoicing the buyer.

Question 10

What is IFF in the QRMP scheme?

Accepted Answer

The Invoice Furnishing Facility (IFF) is an optional facility for QRMP taxpayers to upload B2B invoices for the first two months of a quarter, by the 13th of the following month, up to Rs.50 lakh of invoice value per month. Invoices uploaded through IFF appear in your buyers' GSTR-2B immediately, so they can claim input tax credit without waiting for your quarterly GSTR-1. If your customers are registered businesses that press for timely credit, using IFF keeps them happy. We file IFF for QRMP clients in Madambakkam as part of the standard package.

Question 11

We distribute free samples and run buy-one-get-one offers. How is ITC treated on these?

Accepted Answer

The two are treated very differently. Goods disposed of as gifts or free samples attract the block under Section 17(5)(h), so ITC on inputs used for genuinely free samples must be reversed. However, CBIC Circular 92/11/2019 clarifies that buy-one-get-one offers are not free supplies; they are effectively two goods sold for a single price, tax is charged on that price, and full ITC remains available. Trade discounts recorded in the invoice also do not disturb credit. Pharmaceutical distributors and FMCG dealers in Madambakkam should therefore document promotional schemes carefully, because the same physical giveaway can be creditable or blocked depending on how the offer is structured.

Question 12

What are the common types of GST notices a business can receive?

Accepted Answer

The frequent ones are: REG-03 seeking clarification on a registration application; GSTR-3A for non-filing of returns; ASMT-10 pointing out discrepancies found on scrutiny of returns; DRC-01A intimating an ascertained tax liability before formal proceedings; DRC-01, the show cause notice under Section 73 or 74; ADT-01 intimating a departmental audit; REG-17 proposing cancellation of registration; RFD-08 proposing rejection of a refund claim; and summons under Section 70. Each has its own reply form and deadline, ranging from seven working days to thirty days, so identifying the notice type correctly is the first step in responding. When in doubt, call +91 - 9600 606 444.

Question 13

How do I choose a good GST consultant near me in Madambakkam?

Accepted Answer

Look for four things: familiarity with the GST portal's actual workflows rather than just theory, responsiveness around due dates such as the 11th for GSTR-1 and the 20th for GSTR-3B, transparent fixed pricing instead of vague estimates, and the ability to handle departmental work like clarification notices, amendments and revocations, not just routine filing. Ask how they track your ARNs and deadlines, and whether they share acknowledgements after every filing. ChennaiGST serves businesses across Madambakkam with fixed-fee packages starting at Rs.749, and every filing is confirmed back to you with the portal acknowledgement. Call +91 - 9600 606 444 for a free initial consultation.

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 Madambakkam 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

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 Madambakkam health check.

Question 16

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 17

Why is my e-way bill generation blocked on the portal?

Accepted Answer

Under Rule 138E, the e-way bill facility is blocked when a taxpayer has not filed GSTR-3B (or CMP-08 for composition dealers) for two or more consecutive tax periods. Since an e-way bill is mandatory for moving goods worth more than Rs.50,000, blocking effectively halts dispatches. The remedy is straightforward: file the pending returns with late fee and interest, after which the facility unblocks automatically, usually the next day. Transporters and suppliers can also be affected when a counterparty GSTIN is blocked. We clear return backlogs for businesses in Madambakkam on priority; call +91 - 9600 606 444.

Question 18

I returned an advance because the deal was cancelled. What document do I issue?

Accepted Answer

It depends on how far the paperwork went. If you had issued only a receipt voucher and no tax invoice, you issue a refund voucher under Rule 51 when returning the advance, and the tax paid on that advance can be adjusted. If a tax invoice had already been issued, the cancellation is handled through a credit note under Section 34 instead. The refund voucher records the original receipt voucher reference, the amount refunded and the tax involved. Event managers and contractors see cancellations regularly, and using the wrong document between these two is a common reconciliation error.

Question 19

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 Madambakkam 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.

Question 20

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 21

Which GST office handles Madambakkam businesses?

Accepted Answer

Businesses in Madambakkam (PIN 600126) 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
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.
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.
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.
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.
Annual return preparation	Monthly reconciliations roll naturally into GSTR-9, filed comfortably before 31 December with figures already agreed through the year.	Twelve months of unmatched data reconstructed in December, with differences discovered too late to be corrected cleanly.
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.
