Gst registration and return filing checklist for small businesses in india?

This checklist covers the two essential compliance tasks for small businesses in India under the Goods and Services Tax (GST): getting registered when you cross the threshold, and filing your returns on time. You will learn who must register, what documents are needed, the step-by-step registration process, and a return-by-return filing schedule with due dates and common pitfalls to avoid.

Who Must Register for GST?

Registration is mandatory if your aggregate turnover (pan-India, all supplies, all registrations under the same PAN) exceeds the threshold. For most states, the limit is ₹40 lakh for goods and ₹20 lakh for services. For special category states (like Himachal Pradesh, Uttarakhand, and the North-Eastern states), the limit is ₹20 lakh for goods and ₹10 lakh for services. Exempt from registration are businesses making only exempt supplies, or those under the threshold who choose not to register. However, you must register regardless of turnover if you make inter-state supplies, are a casual taxable person, or are required to pay tax under reverse charge.

Documents Required for GST Registration

• PAN of the business (mandatory)
• Aadhaar of the promoter/partner/director (for authentication)
• Photograph of the promoter/authorized signatory
• Proof of business address: rent agreement + landlord’s NOC, or electricity bill, or property tax receipt
• Bank account details: cancelled cheque or bank statement (with IFSC)
• Digital signature (DSC) for companies and LLPs (individuals can use Aadhaar OTP)
• For companies: Certificate of Incorporation, MOA, AOA, Board Resolution
• For partnerships/LLPs: Partnership deed/LLP agreement

Step-by-Step Registration Process

1. Go to the GST portal (gst.gov.in) and click on ‘New Registration’.
2. Enter your PAN, mobile number, and email; you will receive OTPs for verification.
3. You will get a Temporary Reference Number (TRN) – save it.
4. Log in with the TRN and fill Part A (basic details: business name, state, constitution, turnover).
5. Submit Part A; you will get an Application Reference Number (ARN).
6. Within 7 days, fill Part B: add all business locations, bank accounts, authorized signatories, and upload the required documents.
7. Verify the application using Aadhaar OTP or DSC, and submit.
8. The officer will review; if no query, you receive the GSTIN (15-digit) and certificate within 7 working days.
9. If a query is raised, you must respond within 7 days; otherwise the application is rejected.

GST Return Filing: Which Forms and When

For a regular small business, the main returns are GSTR-1 (outward supplies) and GSTR-3B (summary return with tax payment). If you are under the Composition Scheme, you file GSTR-4 annually with quarterly payment. The due dates are:

• GSTR-1 (monthly or quarterly): Monthly filers – 11th of the next month; Quarterly filers (QRMP scheme) – 13th of the month after the quarter.
• GSTR-3B: Monthly – 20th of the next month; Quarterly (QRMP) – 22nd or 24th of the month after the quarter (depending on state).
• GSTR-9 (annual return): 31st December of the next financial year (for regular filers).
• GSTR-4 (composition): 30th April of the next financial year.

Even if you have no sales, you must file a nil return by the due date. Late filing attracts a late fee of ₹50 per day (₹20 for nil returns) plus interest at 18% p.a. on the tax due.

Common Mistakes and How to Avoid Them

• Mismatch between GSTR-1 and GSTR-3B: The tax liability declared in GSTR-1 must match GSTR-3B. If not, you will get an auto-generated notice. Always reconcile before filing.
• Not claiming ITC (Input Tax Credit) on time: You can claim ITC only if your supplier has filed GSTR-1 and the invoice appears in your GSTR-2B. Keep track of your purchase register.
• Wrong HSN codes: Use the correct HSN/SAC code for your goods/services. Wrong codes can lead to refund delays or penalties.
• Ignoring the QRMP scheme: If your turnover is up to ₹5 crore, you can opt for quarterly filing with monthly tax payment (QRMP). This reduces filing frequency but you still pay tax monthly.
• Not filing nil returns: Even a zero-sales month requires a return. Missing it attracts late fees and can lead to cancellation of registration.

Costs and Penalties of Non-Compliance

There is no fee for GST registration itself. The costs are the taxes you collect and pay, and the professional fees if you hire an accountant or tax consultant. Penalties for not filing returns: a late fee of ₹50 per day (₹20 for nil returns) per return, capped at ₹10,000 per return. If you collect tax but fail to pay it, you face a penalty of 100% of the tax amount. Non-filing for six consecutive months can lead to cancellation of your registration, after which you cannot collect GST and must settle all dues.

Frequently Asked Questions

Q: Can I start a business without GST registration if my turnover is below the threshold?
Yes, you can operate without registration, but you cannot collect GST from customers or claim ITC on your purchases. If you sell online through marketplaces like Amazon or Flipkart, registration is mandatory regardless of turnover.

Q: What is the difference between GSTR-1 and GSTR-3B?
GSTR-1 is a detailed statement of all outward supplies (invoices) filed monthly or quarterly. GSTR-3B is a summary return that declares total sales, ITC claimed, and tax payable. You must file both; they must match in terms of tax liability.

Q: Can I file GST returns myself without a CA?
Yes, for small businesses with simple transactions, you can file yourself using the GST portal or offline tools. However, if you have multiple branches, inter-state sales, or complex ITC, professional help is advisable to avoid errors.

Q: What happens if I miss the GSTR-3B due date?
You will be charged a late fee of ₹50 per day (₹20 for nil returns) and interest at 18% p.a. on the tax due. The return can be filed late, but the fees and interest accumulate until filed.

Q: Is the composition scheme beneficial for small businesses?
The composition scheme allows a lower tax rate (1% for traders, 5% for restaurants) but you cannot claim ITC, and you cannot issue tax invoices. It is beneficial if your input tax credit is low and you sell mostly to consumers.

Q: How do I know if my GST registration is active?
You can check on the GST portal under ‘Search Taxpayer’ by entering your GSTIN. The status will show ‘Active’ or ‘Cancelled’. You can also download your registration certificate anytime.
