I'm saying you are not required to keep an inventory. You would enter your income and expenses on Schedule C if you have a profit motive.
Business or Hobby? Answer Has Implications for Deductions
The Internal Revenue Service reminds taxpayers to follow appropriate guidelines when determining whether an activity is a business or a hobby, an activity not engaged in for profit.
In order to educate taxpayers regarding their filing obligations, this fact sheet, the eleventh in a series, explains the rules for determining if an activity qualifies as a business and what limitations apply if the activity is not a business. Incorrect deduction of hobby expenses account for a portion of the overstated adjustments, deductions, exemptions and credits that add up to $30 billion per year in unpaid taxes, according to IRS estimates.
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
