Question 1

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

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

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

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

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 Perambur can assess it the same day.

Question 4

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 5

My SaaS startup in Perambur 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 Perambur 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 6

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 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

We hire security guards from an agency. Should they charge GST or should we pay it ourselves?

Accepted Answer

Check the agency's constitution. Since 1 January 2019, security services by way of supply of security personnel provided by any person other than a body corporate to a registered person fall under reverse charge, so your business pays the 18 percent directly and claims credit. If the agency is a body corporate, such as a private limited company, it charges GST under forward charge on its invoice. Recipients registered under the composition scheme are excluded from this reverse charge entry. Businesses in Perambur commonly pay agencies' forward-charge invoices while also missing their own RCM cases, so an annual review of security and manpower bills is worthwhile.

Question 9

We are constructing our own office building in Perambur. Can we claim ITC on the materials and contractor bills?

Accepted Answer

No. Section 17(5)(c) and (d) block credit on works contract services and on goods or services used for construction of immovable property on your own account, even when the building is used for business. The exception is plant and machinery, which covers apparatus and equipment fixed to earth by foundation or structural support, but expressly excludes land, buildings, telecom towers and pipelines laid outside the factory. Note that the Finance Act 2025 retrospectively substituted the phrase plant or machinery with plant and machinery from 1 July 2017, neutralising the wider reading taken in the Safari Retreats ruling. Structure your capitalisation records to separate plant from civil work.

Question 10

What is the late fee for filing GSTR-9 after the due date?

Accepted Answer

From FY 2022-23 onwards, the late fee is turnover-linked. For turnover up to Rs.5 crore it is Rs.50 per day (Rs.25 CGST plus Rs.25 SGST) capped at 0.04 percent of turnover; for turnover between Rs.5 crore and Rs.20 crore it is Rs.100 per day with the same cap; and above Rs.20 crore it is Rs.200 per day capped at 0.5 percent of turnover. The fee accrues until the date of filing, so delays get expensive for larger businesses. Filing before 31 December avoids the entire cost.

Question 11

What is the last date to file GSTR-9 for a financial year?

Accepted Answer

GSTR-9 for a financial year is due by 31 December of the following financial year. For example, the annual return for FY 2024-25 is due by 31 December 2025, unless the government extends the date by notification. The reconciliation statement GSTR-9C, where applicable, has the same due date and is filed after GSTR-9. Since annual return preparation involves reconciling twelve months of returns with books, we recommend starting by October rather than December. Businesses in Perambur can call +91 - 9600 606 444 to book an early slot with our annual returns team.

Question 12

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 Perambur 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 13

Who must sign GST filings with a DSC, and who can use EVC?

Accepted Answer

Companies and limited liability partnerships must authenticate registration applications and returns with a Digital Signature Certificate of the authorised signatory; the Electronic Verification Code route is not ordinarily available to them, though the government has periodically allowed EVC for companies during specified relaxation windows. Proprietorships, partnerships, HUFs and trusts can freely use EVC, an OTP sent to the authorised signatory's registered mobile and email. The DSC must be a Class 3 signature registered on the portal against the signatory's PAN. If a company's filings fail at the signing step, an expired or unregistered DSC is the usual culprit.

Question 14

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 Perambur should be papered before the season starts, not after.

Question 15

I declare income under Section 44ADA. Does that mean I am exempt from GST?

Accepted Answer

No, this is a common myth. Section 44ADA is a presumptive taxation scheme under the Income Tax Act that lets professionals declare fifty percent of gross receipts as income; it has nothing to do with GST. GST liability depends solely on aggregate turnover crossing the registration threshold and the nature of your supplies. In fact, the two departments now cross-match data, so gross receipts reported in your ITR and Form 26AS that exceed the GST turnover you declared are a known trigger for notices. Treat the two laws as parallel obligations, each with its own limits and filings.

Question 16

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 17

What is the GST rate on a works contract for a commercial building?

Accepted Answer

Under GST, a works contract relating to immovable property is treated wholly as a supply of services, and the standard rate is 18 percent on the contract value, with the contractor eligible for input tax credit on cement, steel and other inputs. This applies to construction, fabrication, erection, repair and renovation contracts for factories, offices and commercial buildings. The old VAT-plus-service-tax splitting of material and labour is gone; one rate applies to the whole consideration. Contractors should also note that free-issue materials supplied by the client can affect valuation, so contract drafting deserves attention before quoting.

Question 18

What happened to the old 12 percent and 28 percent GST slabs?

Accepted Answer

Both slabs were abolished with effect from 22 September 2025. Nearly all goods that were at 12 percent moved down to 5 percent, and the bulk of the 28 percent items moved to 18 percent, with only a small set of luxury and demerit goods shifted up to the special 40 percent rate. This means old rate charts, printed price lists and software masters created before September 2025 are unreliable. Before quoting or billing, confirm the current rate against the CBIC rate notifications for your exact HSN code, or call +91 - 9600 606 444 and we will verify it for your product list.

Question 19

Do you provide GSTR-1 & GSTR-3B monthly filing for businesses on Agaram?

Accepted Answer

Yes. We serve businesses on and around Agaram in Perambur — shops, offices, godowns and home-run businesses alike. Document pickup can be arranged at your premises, or you can send everything on WhatsApp and complete monthly returns without leaving your counter. Call +91 - 9600 606 444 and mention your location; a consultant will confirm the fee and timeline immediately.

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

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 Perambur 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.

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.
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.
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.
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.
