Scenario: I own my own business (LLC). There is a business-related conference that I wish to attend that requires travel. I assume airfare, cabs, hotel and conference tickets are all obvious expenses that I can use my American Express Business card on. But what about meals? Can I expense meals? What are other things can and cannot be expensed?
The IRS Guidance pertaining to the subject. In general the best I can say is your business expense may be deductible. But it depends on the circumstances and what it is you want to deduct.
Taxpayers who travel away from home on business may deduct related expenses, including the cost of reaching their destination, the cost of lodging and meals and other ordinary and necessary expenses. Taxpayers are considered “traveling away from home” if their duties require them to be away from home substantially longer than an ordinary day’s work and they need to sleep or rest to meet the demands of their work. The actual cost of meals and incidental expenses may be deducted or the taxpayer may use a standard meal allowance and reduced record keeping requirements. Regardless of the method used, meal deductions are generally limited to 50 percent as stated earlier. Only actual costs for lodging may be claimed as an expense and receipts must be kept for documentation. Expenses must be reasonable and appropriate; deductions for extravagant expenses are not allowable. More information is available in Publication 463, Travel, Entertainment, Gift, and Car Expenses.
Expenses for entertaining clients, customers or employees may be deducted if they are both ordinary and necessary and meet one of the following tests:
Directly-related test: The main purpose of the entertainment activity is the conduct of business, business was actually conducted during the activity and the taxpayer had more than a general expectation of getting income or some other specific business benefit at some future time. Associated test: The entertainment was associated with the active conduct of the taxpayer’s trade or business and occurred directly before or after a substantial business discussion.
Publication 463 provides more extensive explanation of these tests as well as other limitations and requirements for deducting entertainment expenses.
Taxpayers may deduct some or all of the cost of gifts given in the course of their trade or business. In general, the deduction is limited to $25 for gifts given directly or indirectly to any one person during the tax year. More discussion of the rules and limitations can be found in Publication 463.
If your LLC reimburses you for expenses outside of this guidance it should be treated as Income for tax purposes.
Edit for Meal Expenses:
Amount of standard meal allowance. The standard meal allowance is the federal M&IE rate. For travel in 2010, the rate for most small localities in the United States is $46 a day.
Alternately you could reimburse at a per diem rate
