How to File GST Returns Online in India: Step-by-Step Guide for Beginners
The introduction of Goods and Services Tax (GST) has completely reshaped India’s taxation system, making compliance more streamlined yet mandatory for businesses. Every GST-registered entity is required to file returns within the prescribed timelines. For newcomers, however, the online GST return filing process in India can appear confusing.
If you are a startup founder, small business owner, or entrepreneur just getting started, this article will serve as a comprehensive beginner’s guide to filing GST returns online—covering the process, documents required, due dates, and common mistakes to avoid.
Understanding GST Returns
A GST return is a digital document submitted to the Government of India through the GST portal. It reports crucial details such as:
- Sales and purchase transactions
- Input Tax Credit (ITC) claimed
- Output tax liability
- Taxes already paid
In simple terms, filing a GST return means officially declaring your business’s tax records to the government.
Who is Required to File GST Returns?
The obligation to file GST returns applies to different types of taxpayers in India, including:
- Regular GST-registered businesses
- Entities under the Composition Scheme
- Input Service Distributors (ISD)
- E-commerce operators
- Non-resident taxable persons
If your business turnover exceeds ₹40 lakh for goods or ₹20 lakh for services (in most states), GST registration and return filing become mandatory.
Types of GST Returns in India
Different categories of returns exist, depending on the nature of your business and registration:
- GSTR-1 – Details of outward supplies (sales)
- GSTR-3B – Summary of sales, purchases, ITC, and tax liability
- GSTR-4 – For taxpayers under the Composition Scheme
- GSTR-5 – For non-resident taxable persons
- GSTR-6 – For Input Service Distributors
- GSTR-7 – For businesses deducting TDS under GST
- GSTR-9 – Annual return for regular taxpayers
- GSTR-9C – Reconciliation statement (if applicable)
For most small and medium businesses, GSTR-1 and GSTR-3B are the two primary returns filed on a monthly or quarterly basis.
Documents Needed for GST Return Filing
Before beginning the process, make sure you have the following details ready:
- GSTIN (GST Identification Number)
- Sales invoices with GST breakdown
- Purchase invoices for ITC claims
- Debit and credit notes
- Bank details for tax payments
- HSN/SAC codes for goods and services
Having these documents handy ensures a smooth and error-free filing experience.
