Affect both income statement and balance sheet accounts.

An increase in owner’s capital is an example of a transaction that affects both income statement an balance sheet accounts. This is because owner's capital is an account on the balance sheet (assets) and an increase in owner's capital means an increase in the net income value of the company on the income statement. This transaction is recorded by debiting the owner's capital account on the balance sheet and debiting the income statement account. The overall result is an increase in net income as well as an increase in owner's capital on the balance sheet.
