GST Registration Documents Required: Complete List for 2026

ClearTax Free Beginner India

The single most useful thing to print out before you start: a checklist by business constitution so you gather every document in one pass instead of getting a REG-03 query for a missing bank proof.

  • Separates required documents by constitution of business (proprietorship, partnership, LLP, HUF, company), address ownership type, and authorised signatory.
  • Notes accepted proof types for principal place of business (rent agreement, electricity bill, municipal khata, NOC).
  • Flags the file size and format limits (images under 100 KB, PDF/JPG) that trip up first timers.
