Other Services

Administrative changes and technical requests use separate GST procedures.

Key requirements

This directory covers notifying business-name, address and financial-year changes, changing accounting periods and applying for special periods. It also links liquidation obligations for companies and liquidators, advance rulings and technical clarification requests. A technical question about an existing treatment is different from requesting a ruling on a particular proposed arrangement. Select the process matching the issue and prepare its required facts and documents. Accounting-period changes do not themselves cancel registration, while liquidation does not automatically end GST responsibilities. Use the detailed page to confirm the applicable approval or notification step.
