What portion of the cost of capital expenditures is deductible when the taxpayer owns their home?

The deductible portion of capital expenditures for homeowners is determined based on how these expenditures impact the property value. When homeowners make capital improvements, such as renovations or additions, these costs can often be reflected in the property's enhanced market value.

When considering the definition of capital expenditures in relation to homeownership, it is important to note that improvements that add significant value, prolong the property's useful life, or adapt the property to new uses can be capitalized. However, for tax purposes, the IRS generally does not allow the immediate deduction of these costs in the year they occur. Instead, these costs increase the basis of the property.

In the context of tax deductions related to home ownership, only the portion of the expenditure that exceeds any corresponding increase in property value can potentially be considered for deductions under certain tax provisions, particularly when the property is sold. Hence, option B indicates that the deductible portion is the part exceeding the increase in property value. This aligns with tax principles, where capital improvements are taken into account when assessing gains or losses upon sale, affecting the property’s adjusted basis.

The other options do not accurately reflect tax treatment of capital expenditures. Some suggest a complete deduction, others propose caps on deductibility, or imply no deduction is possible, which does not align
