You can deduct business expenses on your income tax return. These are the current operating costs of running your business. To be deductible, a business expense must be both ordinary and necessary. An ordinary expense is one that is common and accepted in your field of business, trade, or profession. A necessary expense is one that is helpful and appropriate for your business, trade, or profession. An expense does not have to be indispensable to be considered necessary.
The following are brief explanations of some expenses that are of interest to people starting a business. There are many other expenses that you may be able to deduct. See your form instructions and Publication 535, Business Expenses.
