## Section 25(2) read with Rule 11 — State-wise Registration
### A. One Registration per State (default)
- GST registration is State-wise, not centralized.
- Business with branches in multiple States → separate registration in each State.
- Within a single State → one registration with one Principal Place of Business (PPoB) and other branches treated as Additional Places of Business (APoB).
### B. Separate Registration for Multiple Places of Business in Same State/UT
- Taxpayer may opt for separate registrations based on business needs.
- Apply in Form GST REG-01 for each place of business.
- Tax must be paid on supplies between such separately registered places of business.
- A tax invoice / bill of supply must be issued for inter-branch supplies.
- Rules 9 and 10 (verification & grant of registration) apply mutatis mutandis.
### C. Composition Levy Interaction
- If a person pays tax under the normal scheme for one separately registered place → cannot opt for composition levy for another place.
- If any one separately registered place becomes ineligible for composition levy → all other places also become ineligible.
