Answer

The tax treatment of the cost of installing hardwood floors for patient support in a home office depends on the primary purpose of the expenditure and whether it qualifies as a deductible medical expense, a business expense, or a capital improvement.

1. Medical Expense Deduction (IRC §213)

General Rule: Under IRC §213(a), a taxpayer may deduct expenses paid during the taxable year for medical care of the taxpayer, spouse, or dependents, to the extent such expenses exceed 7.5% of adjusted gross income. "Medical care" includes amounts paid for the diagnosis, cure, mitigation, treatment, or prevention of disease, or for the purpose of affecting any structure or function of the body.

Capital Expenditures for Medical Care: Capital expenditures that are made primarily for medical care may be deductible, but only to the extent that the cost exceeds any increase in the value of the property. However, certain modifications made to accommodate a residence to a disabled condition (such as ramps, widened doorways, and similar modifications) are generally considered not to increase the value of the home and are fully deductible as medical expenses if their primary purpose is medical care.

Application to Hardwood Floors:- If the hardwood floors are installed specifically to accommodate a medical condition (e.g., to provide a stable, supportive surface for a patient with mobility issues), and the primary purpose is medical care, the cost may be deductible as a medical expense.- If the installation increases the value of the home, only the portion of the cost that exceeds the increase in value is deductible. If there is no increase in value, the full cost is deductible.- The taxpayer must be able to substantiate that the primary purpose of the expenditure was medical care, not general home improvement or aesthetic reasons.

Example: If a physician recommends hardwood floors to prevent falls for a patient with a disability, and the floors are installed for this reason, the cost may be deductible as a medical expense, subject to the above limitations.

2. Business Expense Deduction (Home Office)

General Rule: If the home office is used regularly and exclusively for business, expenses related to the business use of the home may be deductible as business expenses under IRC §162. This includes repairs and maintenance, but capital improvements (such as installing new hardwood floors) must be depreciated over the appropriate recovery period.

Capital Improvements: The cost of installing hardwood floors in a home office is a capital improvement. For a home office, the business portion of the cost is depreciated over 39 years as nonresidential real property under MACRS.

  • The business-use percentage of the cost (based on the proportion of the home used for business) is depreciable.
  • If the improvement benefits only the office, it is a direct expense; if it benefits the entire home, it is an indirect expense and must be allocated accordingly.

No Double Deduction: If the cost is claimed as a medical expense, it cannot also be depreciated as a business expense. The taxpayer must choose the most appropriate treatment based on the facts.

3. Key Considerations

  • Primary Purpose: The taxpayer must establish that the primary purpose of the hardwood floor installation is medical care to claim a medical expense deduction. If the purpose is to improve the home office for business, it is a capital improvement subject to depreciation.
  • Increase in Value: For medical expense deduction, if the installation increases the value of the home, only the excess over the value increase is deductible.
  • Documentation: The taxpayer should retain documentation, such as a physician’s recommendation and evidence of the medical necessity, to support the deduction.

4. Summary Table

ScenarioTax Treatment
Installed primarily for medical care (no value increase)Full cost deductible as medical expense (subject to 7.5% AGI floor)
Installed primarily for medical care (value increase)Deductible to the extent cost exceeds value increase
Installed primarily for business use (home office)Depreciate business-use portion over 39 years (MACRS)
Installed for both medical and business reasonsMust allocate cost and cannot double-deduct

Conclusion: The cost of installing hardwood floors for patient support in a home office may be deductible as a medical expense if the primary purpose is medical care and the cost does not increase the value of the home, or only to the extent it exceeds any value increase. If the primary purpose is business use, the cost is a capital improvement and the business-use portion is depreciated over 39 years. The taxpayer must not claim both deductions for the same expenditure and should maintain documentation to substantiate the deduction.
