From the IRS…
Most types of income are taxable, but some are not. Income can include money, property or services that you receive. Here are some examples of income that are usually not taxable:
• Child support payments;
• Gifts, bequests and inheritances;
• Welfare benefits;
• Damage awards for physical injury or sickness;
• Cash rebates from a dealer or manufacturer for an item you buy; and
• Reimbursements for qualified adoption expenses.
Some income is not taxable except under certain conditions. Examples include:
• Life insurance proceeds paid to you because of an insured person’s death are usually not taxable. However, if you redeem a life insurance policy for cash, any amount that is more than the cost of the policy is taxable.
• Income you get from a qualified scholarship is normally not taxable. Amounts you use for certain costs, such as tuition and required course books, are not taxable. However, amounts used for room and board are taxable.
All income, such as wages and tips, is taxable unless the law specifically excludes it. This includes non-cash income from bartering – the exchange of property or services. Both parties must include the fair market value of goods or services received as income on their tax return.
