GST registration — what it is and when it applies
Goods and Services Tax (GST) registration is required once your business crosses certain activity or turnover conditions, and it changes how you invoice, collect tax, and file returns.
This section is general educational orientation, not legal, tax, or professional advice. Registration thresholds, rates, and rules change and often vary by state — always confirm current requirements with a qualified chartered accountant, company secretary, or lawyer before acting.
What GST registration means
Once registered, a business collects GST on applicable sales, can claim credit for GST paid on business purchases, and must file periodic returns.
Turnover-based and activity-based triggers
Registration is generally required beyond certain annual turnover levels, and separately required for certain activities (like inter-state sales or e-commerce) regardless of turnover. These thresholds are set by law and do change — verify the current figures on the official GST portal or with a CA rather than assuming a remembered number is still current.
Voluntary registration
Even businesses below the mandatory threshold can register voluntarily, which is sometimes worthwhile to claim input tax credit or to appear more credible to B2B customers who prefer GST-registered vendors.
Ongoing compliance
Registration brings recurring obligations — periodic return filing and accurate invoicing — that are easier to build into your systems from day one than to retrofit later.
