Example 2: John owns a web design company that operates from his home. His business expenses include the cost of his computer, internet bill, website hosting, online advertising, and even a portion of his home’s rent/mortgage and utilities (known as Home Office Deduction) given he uses part of his home exclusively for his business. These can all potentially qualify as tax-deductible expenses.3. Example 3: Laura owns a consulting firm.
