Can I write off utilities if working from home?

Utilities can be deducted as part of the home office deduction if you use a portion of your home exclusively and regularly for business purposes. This includes expenses like electricity, heating, and water. However, only the portion of these expenses that directly relates to the business use of your home is deductible. For example, if your home office occupies 10% of your home's square footage, you can deduct 10% of your utility bills.
