My daughter competes at skeet competitions and received three 1099 misc forms with amount in box 3, can she file schedule c for expenses incurred?

If she qualifies, yes she can say it is a business. However, the fact that it is entered in Box 3, indicates that the issuers consider this a prize. It is very likely that this is how it should be treated, expenses notwithstanding.

In general, taxpayers may deduct ordinary and necessary expenses for conducting a trade or business. An ordinary expense is an expense that is common and accepted in the taxpayer’s trade or business. A necessary expense is one that is appropriate for the business. Generally, an activity qualifies as a business if it is carried on with the reasonable expectation of earning a profit.

In order to make this determination, taxpayers should consider the following factors:

• Does the time and effort put into the activity indicate an intention to make a profit?
• Does the taxpayer depend on income from the activity?
• If there are losses, are they due to circumstances beyond the taxpayer’s control or did they occur in the start-up phase of the business?
• Has the taxpayer changed methods of operation to improve profitability?
• Does the taxpayer or his/her advisors have the knowledge needed to carry on the activity as a successful business?
• Has the taxpayer made a profit in similar activities in the past?
• Does the activity make a profit in some years?
• Can the taxpayer expect to make a profit in the future from the appreciation of assets used in the activity
