What’re Deductible Business Expenses?

Every small business owner wants to know how to legally minimize his or her tax obligations. You know that the tax code allows you to deduct costs of doing business from your gross income. You are taxed on your net business profit. How to maximize your deductible business expense to lower your taxable profit then?

What are deductible business expenses? You would think the IRS has a list, but the Internal Revenue Code provides little detail other than “There shall be allowed as a deduction all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business”. The tax code does not define either “ordinary” or “necessary”. The federal courts have tried to figure out what Congress intended and apply it to a particular set of facts. “ordinary” has been held by courts to mean “normal, common and accepted under the circumstances by the business community.” “Necessary” means “appropriate and helpful” to your business. The law specifically mentions salaries and other compensation for personal services, traveling expenses, rent, interest, taxes, pension and profit-sharing expenses and some other expenses. The IRS Regulations, court cases and other rulings provide guidance additional guidance. The list below is general in nature but should provide a starting point.

Please keep in mind that only expenses related to your business are deductible. For example, if you buy a computer and use it 75% for business and 25% for personal use, you can depreciate only the 75% used for business. Thus, for any of the items listed below, only the business portion is deductible. In order to secure a deduction you need not only an expense that qualifies as deductible, you also need have adequate documentation to support the expense. That generally means proving the expenditure was incurred (typically with an invoice) and proving it was paid (canceled check, receipt, etc.).
