In one line

Most of the CGST Act – scope of supply, time and value, input tax credit, registration, invoicing, returns, payment, refunds, assessment, audit, demands, appeals and offences – applies to IGST as well, with the changes stated here, such as the doubled thresholds and penalty limits.

What this means in practice

The parts that actually decide cases — the things a practitioner checks first.

1

The doubled figures matter: the penalty ceilings and the registration threshold references in the CGST Act apply to IGST with the modifications stated here – so a Rs 10,000 CGST penalty reads as Rs 20,000 in an IGST case.
