Home generators used for personal purposes are generally not tax-deductible. However, there might be certain circumstances where a home generator could be considered a medical expense if it's prescribed by a doctor for medical reasons. In such cases, a portion of the cost might be deductible as a medical expense on your federal income tax return if it exceeds a certain percentage of your adjusted gross income. Always consult with a tax professional or refer to the latest IRS guidelines to determine any potential deductions related to home generators.
