With the introduction of the self-assessment system in 1992, the Commissioner of Income Tax does not raise assessments or send notices to taxpayers except in two circumstances. Explain these two circumstances

Three circumstances under which CIT can send notices or raise assessments:

• A person has not submitted a return of income and the CIT considers that the person has income chargeable to tax for that years
• CIT considers that a person has been assessed or has assessed himself at a less amount in relation to income or tax payable.
• Where CIT issues an agreed amended assessment but later discovers unassessed income.
