GST Registration & Filing: What Every Small Business Must Know

Goods and Services Tax (GST) has transformed the way businesses operate in India. Whether you're running a small shop, offering professional services, or managing an online store, understanding GST is crucial. Many small businesses delay registration or file returns incorrectly resulting in penalties and missed benefits.

At Proviconn, we help you simplify compliance. This guide breaks down what small business owners must know about GST registration and filing.

1. What Is GST and Why Does It Matter?

GST is a single indirect tax that has replaced multiple taxes like VAT, service tax, and excise duty. It applies to the supply of goods and services across India.

Why it matters:

  • Avoid penalties and legal issues

  • Improve credibility with vendors and clients

  • Claim Input Tax Credit (ITC) and reduce tax burden

  • Essential for participating in e-commerce and government tenders

2. Who Needs to Register for GST?

As per the GST Act, registration is mandatory for:

  • Businesses with an annual turnover of ₹40 lakh or more (₹20 lakh for service providers in most states)

  • Inter-state suppliers of goods or services

  • E-commerce sellers (even if turnover is below threshold)

  • Businesses with reverse charge liability

  • Casual taxable persons and non-resident taxable persons

Note: Voluntary registration is also possible—and often beneficial for startups seeking credibility and tax credits.

3. Documents Required for GST Registration

Basic documents include:

  • PAN Card of the business or owner

  • Aadhar Card

  • Business address proof (rent agreement or electricity bill)

  • Bank account details (cancelled cheque or bank statement)

  • Photographs of proprietor/partners/directors

  • Incorporation certificate or partnership deed

4. How to Register for GST?

Step-by-step process:

  1. Visit the GST portal: www.gst.gov.in

  2. Click on "New Registration" and fill in business details

  3. Receive Temporary Reference Number (TRN)

  4. Login with TRN to complete the application

  5. Upload documents and complete e-verification

  6. Receive GSTIN (GST Identification Number) in 3-7 working days

5. Understanding GST Returns

Filing GST returns is mandatory—even if no transactions occur. Types of returns include:

  • GSTR-1: Outward sales (monthly or quarterly)

  • GSTR-3B: Summary of sales, purchases, and tax liability (monthly)

  • GSTR-9: Annual return (mandatory for turnover above ₹2 crore)

  • CMP-08: Quarterly return for composition scheme dealers


Deadlines

  • GSTR-1: 11th of next month / quarterly as per QRMP scheme

  • GSTR-3B: 20th of next month (staggered by state)

  • CMP-08: 18th of the month following the quarter

6. Penalties for Non-Compliance

Non-compliance can result in:

  • Late fees: ₹50/day (₹20 for NIL returns)

  • Interest @ 18% p.a. on delayed payment

  • Suspension or cancellation of GSTIN

7. Common Mistakes to Avoid

  • Missing deadlines

  • Not reconciling GSTR-2A with purchase invoices

  • Claiming ineligible Input Tax Credit

  • Filing returns with errors or omissions

8. Benefits of Proper GST Compliance

  • Seamless ITC claims = lower cost of operations

  • Builds trust with clients and vendors

  • Eligibility for loans, tenders, and scaling across India

  • Avoids scrutiny and penalties from tax authorities
