Can I write off power bill
TL;DR
You can write off a portion of your power bill if you use part of your home exclusively for business purposes, subject to specific IRS rules and calculations.
Detailed Answer
Where to Put It on the Tax Form
Schedule C, Line 30 for sole proprietors or Form 8829 for detailed home office expenses.
Real World Example
A freelance graphic designer uses a spare bedroom as a home office, which is 150 square feet of her 1,500 square foot home. She can deduct 10% of her annual power bill of $1,200, which amounts to a $120 deduction.
Calculation Required
A calculation is required for this deduction.
Calculate the percentage of your home used for business by dividing the square footage of your home office by the total square footage of your home. Multiply this percentage by your total power bill to determine the deductible amount.
Audit Risk & Documentation Tips
Moderate audit risk. Keep detailed records of your home's total square footage and the square footage of your home office. Maintain utility bills and any documentation showing the business use of the space, such as a floor plan or photographs. Ensure the space is used exclusively for business to support your claim.
