Final answer:
All tax returns have three main sections: income, adjustments, and deductions. Income includes dividends, capital gains, and wages. Adjustments and deductions include retirement savings contributions, student loan interest, dependent care, and certain business expenses.
Step-by-step explanation:
The income section of a tax return reports all sources of income such as dividends, capital gains, and wages. Retirement savings contributions, student loan interest, and certain business expenses are included in the adjustments section. Lastly, to reduce the total amount of taxes owed, claims for expenses such as dependent care are listed in the deductions section.
