GST registration is one of the first compliance questions every growing business faces. Register too late and you risk penalties; register without needing to and you take on filing obligations you could have avoided. Here is how to decide and how to do it.
The turnover thresholds
For most businesses supplying goods, GST registration becomes mandatory once annual turnover crosses Rs 40 lakh (Rs 20 lakh in special-category states). For service providers the common threshold is Rs 20 lakh (Rs 10 lakh in special-category states). These limits are the usual trigger, but they are not the whole story.
When registration is compulsory regardless of turnover
- You make inter-state taxable supplies of goods.
- You sell through e-commerce platforms that collect TCS.
- You are liable to pay tax under reverse charge.
- You are a casual or non-resident taxable person.
- You act as an agent or input service distributor.
Documents you will need
Keep your PAN, Aadhaar, a recent photograph, proof of business address, bank account details and your business constitution documents ready. For a company or LLP you will also need incorporation papers and authorised-signatory details. Having these in order makes the application quick.
The step-by-step process
Apply on the GST portal with Part A (PAN, mobile and email verification) followed by Part B (business details, promoters, place of business and documents). After submission you complete Aadhaar authentication, the application is processed, and on approval you receive your GSTIN. Most clean applications are approved within a few working days.
What changes after you register
Once registered you must charge GST on taxable supplies, file periodic returns, and maintain proper records. Voluntary registration can also make sense if your buyers want input credit - but only take it on when you are ready to handle the ongoing filings.
