If you're self-employed and work from home, you may be able to deduct the cost of your home office from your taxes. The deduction can be taken for a portion of your mortgage interest, rent, utilities, and insurance. To claim the deduction, your home office space must be used exclusively for business and it must be the principal place of business. You don't have to own the property to claim the deduction, but if you do own the property, you can only deduct the business-use portion of the expenses. Form 8829 is used to calculate the deduction for business use of your home. It should be noted that this is only applicable to self-employed individuals and not remote workers, who are employed by a business and receive a W-2 tax form.
