You don't have to register on day one — but the moment you should is easy to miss. Here's the checklist.
When registration is mandatory
Turnover over ₹40 lakh (₹20 lakh for services) in a financial year, or you sell inter-state, or you sell via e-commerce platforms — register immediately.
When you should register voluntarily
If you're B2B and your clients want input tax credit, register early. Otherwise you'll leave money on the table by pricing without GST.
What you must file after registration
GSTR-1 (outward supplies) and GSTR-3B (summary + payment) monthly or quarterly depending on the QRMP scheme you opt for. Annual return GSTR-9 if turnover > ₹2 Cr.
The mistakes that cost most
Missing invoice matching, wrong HSN codes, and not claiming input tax credit within the deadline. These are boring to fix but expensive to ignore.
Talk first.
Decide with clarity.
Before choosing only on price, speak with someone who understands what First-Time Founders truly need.
