How do I know what business expenses I can deduct?

Deductible business expense must be:

  1. Ordinary and necessary for the business
  2. not extravagant, and
  3. primarily for the business (not personal)

Basically, money you spend in a reasonable way, with an expectation of bringing in business revenue, is a deductible expense. To claim the deductions, a business must be operated to make a profit.

Types of Deductible Business Expenses

Cost of Goods Sold

If your business manufactures products or purchases them for resale, some of your expenses may be included in figuring the cost of goods sold. You deduct the cost of goods sold from your gross receipt to figure your gross profit for the year. If you use an expense to figure the cost of goods sold, you cannot deduct it again as a business expense. The following are types of expenses that go into figuring the cost of goods sold.

Ordinary and Typical Business Expenses

An ordinary expense is one that is common and accepted in your trade or business. A necessary expense is one that is helpful and appropriate for your trade or business. An expense does not have to be indispensable to be considered necessary. The following is a list of some of the most common ordinary and typical business expenses that a deductible.

Types of Non-Deductible Business Expenses

Capital Expenses

You must capitalize, rather than deduct, some costs. These costs are a part of your investment in your business and are called capital expenses. There are three types of costs you capitalize.

Personal Expenses

Generally, you cannot deduct personal, living, or family expenses. However, if you have an expense for something that is used partly for business and partly for personal purposes, you must divide the total cost between the business and personal parts. You can deduct as a business expense only the business part.
