Question 1

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 2

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

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 3

What is the due date for GSTR-3B in Tamil Nadu?

Accepted Answer

For monthly filers, GSTR-3B is due on the 20th of the following month. If you are registered in Tamil Nadu and have opted for the QRMP scheme, your quarterly GSTR-3B is due on the 22nd of the month following the quarter. GSTR-3B is the summary return through which you actually pay tax, so missing it attracts a late fee of Rs.50 per day (Rs.20 for nil returns) plus interest at 18 percent per annum on tax paid late.

Question 4

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 5

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 6

How much does GST return filing cost near me in Nanmangalam?

Accepted Answer

Our monthly GST return filing package for businesses in Nanmangalam starts at Rs.749, which covers GSTR-1 and GSTR-3B preparation, GSTR-2B reconciliation for input tax credit, tax computation and filing reminders. There are no hidden charges; government late fees, if any, are separate and payable on the portal. Pricing depends on invoice volume, so a trader with high invoice counts may be quoted differently from a small service provider. Call +91 - 9600 606 444 for an exact quote for your business, and ChennaiGST will confirm the fee in writing before you commit.

Question 7

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 8

When is GSTR-1 due for my business in Nanmangalam?

Accepted Answer

GSTR-1, the statement of outward supplies, is due on the 11th of the following month for taxpayers filing monthly. If you have opted for the QRMP scheme, the quarterly GSTR-1 is due on the 13th of the month after the quarter ends. Filing on time matters because your invoices flow into your buyers' GSTR-2B, which decides their input tax credit. Our team in Nanmangalam tracks these dates for every client so nothing slips. Call +91 - 9600 606 444 if you need a filing reminder set up.

Question 9

How do I pay tax monthly under QRMP if the return is only quarterly?

Accepted Answer

For the first two months of each quarter, tax is deposited through challan PMT-06 by the 25th of the following month. You can use the fixed sum method, paying 35 percent of the tax paid in cash in the previous quarter (or 100 percent of the tax paid in cash in the last month of the previous quarter if you were a monthly filer), or the self-assessment method, paying actual liability after adjusting input tax credit. The third month's tax is settled in the quarterly GSTR-3B itself. We compute the safer option for each client in Nanmangalam every month.

Question 10

What are the conditions under Section 16 I must satisfy before claiming any input tax credit?

Accepted Answer

Section 16(2) prescribes cumulative conditions: you must hold a valid tax invoice or debit note, you must have actually received the goods or services, the supplier must have paid the tax to the government, and you must have filed your GSTR-3B. Added to these, the invoice must appear in your GSTR-2B and must not be restricted there. In practice this means a genuine purchase can still fail the test if your supplier defaults. We advise businesses in Nanmangalam to maintain proof of receipt, such as delivery challans and goods inward registers, because officers increasingly demand evidence of actual receipt during verification.

Question 11

We are constructing our own office building in Nanmangalam. 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 12

The GST rate on my product changed. Which rate applies to pending orders and invoices?

Accepted Answer

Section 14 of the CGST Act decides this by looking at three events: the date of supply, the date of invoice and the date of payment. Broadly, if any two of the three events fall after the rate change, the new rate applies; if two fall before, the old rate applies. So goods delivered in Nanmangalam before 22 September 2025 but invoiced and paid for afterwards attract the new rate, while goods delivered and invoiced earlier keep the old rate even if payment came later. Document dates carefully during any transition window, because officers test these invoices in scrutiny.

Question 13

Our head office in Nanmangalam 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 14

What are the most common mistakes Chennai businesses make with GST refunds and ITC?

Accepted Answer

The recurring ones we see across Nanmangalam are: missing the two-year limitation for RFD-01, mismatches between GSTR-1, GSTR-3B and shipping bill data that stall export refunds, forgetting the April LUT renewal, claiming ITC on invoices absent from GSTR-2B, ignoring blocked credits under Section 17(5), breaching the 180-day supplier payment rule, and treating deficiency memos as rejections instead of refiling within limitation. Each of these is preventable with a simple monthly checklist and a year-end reconciliation. ChennaiGST builds exactly this discipline into its retainer engagements; call +91 - 9600 606 444 if any of these sounds familiar.

Question 15

What falls under the 18 percent standard rate of GST now?

Accepted Answer

The 18 percent slab is the standard rate for most services and for goods that are neither essentials nor demerit items. Notably, several products that earlier suffered 28 percent moved down to 18 percent from 22 September 2025: air conditioners, televisions of all sizes, dishwashers, cement, small cars and motorcycles up to 350cc, and most auto parts. Apparel and footwear priced above Rs.2,500 per piece also fall at 18 percent. Most professional, business support and repair services billed by professional firms continue at 18 percent with full input tax credit.

Question 16

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 Nanmangalam 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 17

Which food items became completely tax-free under GST 2.0?

Accepted Answer

From 22 September 2025, UHT milk, pre-packaged and labelled paneer and chena, and all Indian breads including roti, chapati, paratha and khakhra attract nil GST. In the pharma space, thirty-three notified lifesaving drugs and medicines for cancer and rare diseases also moved to nil rate. Remember that selling nil-rated goods still has compliance effects: you issue a bill of supply instead of a tax invoice for such items, and input tax credit attributable to nil-rated supplies must be reversed proportionately under Rules 42 and 43. Grocery retailers in Nanmangalam commonly need help splitting mixed billing correctly.

Question 18

What are the rules for numbering GST invoices?

Accepted Answer

The invoice serial number must be consecutive, must not exceed sixteen characters, and may contain alphabets, numerals and the special characters hyphen and slash, in one or multiple series. Each number must be unique for a financial year, so most businesses restart their series every April with a year prefix such as 2026-27/001. Gaps in a series invite questions during audit because officers may suspect unreported invoices, and cancelled invoice numbers should be retained in records with the cancelled copy. The document series you use must also be declared in Table 13 of GSTR-1 each period.

Question 19

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.

Aspect	With ChennaiGST	DIY / Unattended
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.
Supplier defaults	Suppliers who stop uploading invoices are identified within the period and pursued before their default becomes your blocked credit.	Missing supplier invoices surface only when credit is denied, by which time recovering the amount from the vendor is difficult.
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.
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.
Risk of notices	GSTR-1, GSTR-3B and GSTR-2B reconciled before filing, removing the mismatches that trigger most scrutiny notices.	Inconsistent figures across returns quietly build a mismatch history that surfaces later as ASMT-10 scrutiny or a demand notice.
