Final answer:
The most accurate answer is option B, regarding a married filing joint taxpayer with AGI of $500,000 not being able to deduct personal and dependency exemptions, due to the suspension of these exemptions under the Tax Cuts and Jobs Act from 2018 to 2025.
Step-by-step explanation:
The question seeks to identify true statements regarding tax exemptions and deductions. Analyzing the provided options and considering United States tax laws, option B is likely the correct answer because the Tax Cuts and Jobs Act, effective from 2018 to 2025, suspended personal and dependency exemptions. Therefore, a married taxpayer filing jointly with an adjusted gross income (AGI) of $500,000 would not be able to deduct personal and dependency exemptions during this period.
It is important to note, however, that before the Tax Cuts and Jobs Act, both personal exemptions and dependency exemptions were subject to phase-out at certain income levels, contradicting option A. Option C is incorrect as exemptions could be phased out completely, and option D is inaccurate because both itemized deductions and exemptions were previously subject to phase-out. Lastly, option E is incorrect because option B is a true statement.
