How do I add my business (GSTIN)?

1. On Your Businesses, click Add your first GSTIN → (or the + Add another GSTIN tile if you already have one).

2. Enter your business name and your 15-character GSTIN - the state fills in automatically.

   

3. Pick how you file GSTR-1 (Monthly or Quarterly), your turnover slab, then click Save and continue →.

⚠️ The GSTIN is recorded permanently and can't be changed later - double-check it before saving. Not sure if you file monthly or quarterly? It's on your GST portal dashboard under Returns.
