What does section 43 regulate?

It regulates matching, reversal and reclaim of reduction in output tax liability. Read the exact text, conditions, exceptions and transaction date together.

Which subordinate law should be checked?

No direct CGST Rule has been certified in this phase. Notifications, circulars, forms and the corresponding SGST/UTGST layer may also apply.

What evidence should be retained?

Preserve the contract or transaction record, invoice or form, portal acknowledgement, payment/ledger evidence, correspondence, legal working and the official source version used.
