GST Registration in 2025: What Every Business And Online Seller Needs To Know

The Goods and Services Tax (GST), introduced in 2017, replaced multiple indirect taxes to create a unified tax system in India. With ongoing changes in GST regulations, businesses need to stay informed about registration requirements and compliance deadlines.

According to a recent tweet by efiletax, a tax filing and financial solutions organisation, GST registration in 2025 is mandatory for businesses that exceed specific turnover thresholds or start selling online from Day 1. When a business's yearly turnover surpasses Rs 40 lakh, they have to register, while a service provider's turnover exceeds Rs 20 lakh, it must register.

For online sellers, GST registration is mandatory right from the first day of operations, regardless of turnover. This requirement reflects increased government scrutiny of e-commerce activities to ensure transparency and tax compliance.

Businesses must submit monthly returns after registering. The 11th of every subsequent month is the deadline for submitting GSTR-1, which details sales and outgoing supplies. Meanwhile, GSTR-3B, a summary of tax liability and payments, is due by the 20th every month for the previous month's transactions.

Small businesses with turnover below Rs 1.5 crore (goods) or Rs 50 lakh (services) can choose the Composition Scheme, which simplifies filing and lowers tax rates. This option is not available to online sellers.

GST registration requires submission of documents like Aadhaar and PAN cards, business registration certificates, identification and address proof of the owner, proof of business address, bank statements and authorisation letters through the GST portal.

In April 2025, the Central Board of Indirect Taxes and Customs (CBIC) issued guidelines to streamline the registration process. Officers are now instructed to avoid sending notices for minor discrepancies or unnecessary document requests and must seek higher approval before asking for additional paperwork.

This efiletax update highlights the need for GST registration in 2025, particularly for internet enterprises. To stay compliant and steer clear of legal issues, companies must stay up to date on these changes.
