In one line
Migration of persons registered under the earlier laws into GST – the provisional registration in REG-25, the follow-up information in REG-26, and cancellation in REG-28 where the person was not liable. Spent for new taxpayers; it still matters when an old provisional registration is questioned.
How this provision is built
The skeleton, clause by clause — useful when a notice cites a specific sub-clause.
The exact words of the law
3,432 characters, uneditedReproduced from the CBIC text. We explain it above — but you should always be able to read it yourself.
