As long as a defined storage space is used exclusively for business-related items, you may include this space under the Home Office Deduction. Simply add it to your home office space to take the deduction.
You cannot deduct your entire garage, basement or attic if you use only a portion of that space to store inventory or business-related items.. You can us duct tape to set the boundaries of the "business" portion of your garage, basement or attic so that if you are ever audited (very rarely), the IRS agent can see clearly where your home office space ends and your personal space begins.
