Know when you must register for GST and when it is optional but useful.
Turnover limits
A business must register once its annual turnover crosses the prescribed limit. The limit is different for goods and services, and lower in some special category states. Check the current limit for your state before you decide.
Cases where it is compulsory
Some businesses need GST registration whatever their turnover, such as those making inter-state supply of goods, selling through e-commerce platforms, and certain other categories like casual taxable persons and non-resident taxable persons.
Why register even if it is optional
With a GSTIN you can claim input tax credit, sell to larger businesses that insist on a GST invoice, and appear more credible to customers and banks.
Penalty for not registering
Operating without a required registration can lead to penalties and tax recovery with interest, so it is safer to register on time.
