Deductions are not allowable under section 162 or 212 for activities which are carried on primarily as a sport, hobby, or for recreation. The determination of whether an activity is engaged in for profit is to be made by reference to objective standards, taking into account all of the facts and circumstances of each case. Although a reasonable expectation of profit is not required, the facts and circumstances must indicate that the taxpayer entered into the activity, or continued the activity, with the objective of making a profit. In determining whether such an objective exists, it may be sufficient that there is a small chance of making a large profit. Thus, it may be found that an investor in a wildcat oil well who incurs very substantial expenditures is in the venture for profit even though the expectation of a profit might be considered unreasonable. In determining whether an activity is engaged in for profit, greater weight is given to objective facts than to the taxpayer’s mere statement of his intent.
