Cabinet Decision No. 39 of 2019, Article 28, outlines notification duties when an activity is disposed of or ceased. Taxpayers must notify the Authority within 30 days of total or partial cessation. Heirs have 60 days to notify in the event of a taxpayer's death, while liquidators must report their appointment and the completion of liquidation within 30 days. Submitting a final tax return within the period exempts the taxpayer from the separate notification requirement. This ensures the tax authority can close files and assess final liabilities promptly.
