Income. Your basic records prove the amounts you report as income on your tax return. Your income may include wages, dividends, interest, and partnership or S corporation distributions. Your records also can prove that certain amounts are not taxable, such as tax-exempt interest.

Expenses. Your basic records prove the expenses for which you claim a deduction (or credit) on your tax return. Your deductions may include alimony, charitable contributions, mortgage interest, and real estate taxes. You may also have child care expenses for which you can claim a credit.
