What's deductible? 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". That phrase covers about 95% of the items deductible. (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. We've been frequently asked to provide readers with a list of expenses they can deduct. 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. Often that's easy to show--office telephone, normal office supplies, shop tools, etc. But in some cases you may have to show the expenditure was business related. If the item seems out of place in your business, or can have personal uses, be sure you have some sort of documentation to support the expense. Vehicle expenses and other "listed property" as well as travel, meal and entertainment expenses have specific reporting requirements and business/personal use may require allocation. And keep in mind that 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.).

The rules can often be complicated. The best approach is to record all your expenses in detail and discuss them with your accountant or tax advisor.

Here's our list. It's far from all inclusive and some of the items are subject to special rules. We've included comments on certain items. While intended for taxpayers filing a Schedule C, the rules generally apply to all businesses.
