Final answer:
Taxpayers may choose the standard deduction over itemizing after buying a home if their deductible expenses do not surpass the standard deduction amount, especially since the scenario assumes taxes start from the first dollar of income.
Step-by-step explanation:
The question relates to taxpayers who previously itemized deductions and are considering when to start claiming the standard deduction after purchasing a home.
When individuals buy a home, they may have additional deductible expenses such as mortgage interest and property taxes, which can make itemizing more beneficial than taking the standard deduction. However, if these itemized deductions do not exceed the standard deduction amount, a taxpayer may opt for the simplicity and guaranteed benefit of the standard deduction.
Furthermore, our scenario assumes that individuals begin to pay taxes on their first dollar of income without considering the standard deduction and exemption, which simplifies the tax calculation but does not reflect the actual tax code.
