In most cases, home generators are not tax-deductible. However, there are a few exceptions. If you install a solar-powered backup generator, you may qualify for a tax deduction, as long as it’s your primary residence and not a vacation home. In addition, you can get a tax credit if you install a generator due to a medical need. For instance, if you rely on a dialysis machine or chairlift to get around the house, you can write off the cost of a generator on your taxes, if you have confirmation from a doctor. You may want to speak with your financial advisor or tax accountant to see if your circumstances qualify you for a tax deduction.
