Final answer:
Without specific tax information and accounting practices, we cannot determine the exact amount Stephanie must recognize for tax purposes beyond her financial statement income.
Step-by-step explanation:
If Stephanie recognizes $5,000 of income for financial statement purposes this year, the amount she must recognize for tax purposes can vary depending on tax laws and her specific circumstances. Without additional information, such as whether there are differences between financial accounting and tax accounting practices in this scenario, we cannot determine the exact amount that should be recognized for tax purposes. Therefore, the correct answer is option 3: Cannot be determined.
