Case laws

• Deductions must be itemized. This means that the taxpayer must be able to provide detailed information about the deduction, such as the date of the expense, the amount of the expense, and the purpose of the expense.
• Deductions must be ordinary and necessary. This means that the expense must be common and expected for the taxpayer’s business or profession.
• Deductions must be incurred in carrying on a trade or business. This means that the expense must be directly related to the taxpayer’s business or profession.
• Deductions must be substantiated. This means that the taxpayer must have documentation to support the deduction, such as a receipt or invoice.

There are a number of exceptions to these general principles. For example, some deductions are allowed even if they are not itemized, such as the standard deduction. And some deductions are allowed even if they are not ordinary and necessary, such as charitable contributions.
