Business or Hobby? The Rules That Decide Whether Losses Are Deductible

This comes up constantly on small agricultural operations across Parker and Wise counties, and on side ventures generally. If an activity is a business, losses offset other income. If it is a hobby, they do not.

The three-of-five presumption

There is a safe harbour: an activity that shows a profit in three of the last five consecutive years is presumed to be engaged in for profit. Horse breeding and racing activities get a longer window.

That is a presumption, not a rule. Failing it does not automatically make something a hobby, and meeting it does not make the question untouchable. What actually governs is the factor analysis.

The factors that are weighed

• Whether the activity is carried on in a businesslike manner — separate accounts, real books, a business plan.
• The expertise of the taxpayer or their advisers.
• The time and effort devoted to it.
• Whether the assets are expected to appreciate.
• The taxpayer's success in similar activities.
• The history of income and losses, and whether losses are explainable by startup or by circumstances outside control.
• The amount of occasional profits relative to the losses and the investment.
• The taxpayer's financial status — losses are viewed differently where there is substantial other income.
• Whether there are elements of personal pleasure in the activity.

No single factor decides it. The last one is where a lot of small agricultural and equine operations run into difficulty.

What strengthens the position

1. Separate bank account and credit card, used only for the activity.
2. Real bookkeeping, kept contemporaneously rather than reconstructed.
3. A written business plan that is actually followed and revised.
4. Documented changes made in response to losses — evidence you were trying to make it profitable.
5. Advice sought from people with relevant expertise, and records of it.
6. Time records showing genuine effort.
7. Marketing activity of some kind.

The practical consequence

Under current law, hobby expenses are not deductible at all against hobby income for most taxpayers — while the hobby income remains fully taxable. That is a harsh outcome and it is why the classification matters more than people assume.

Our approach

We will tell you honestly where an activity sits and what would need to change for the position to be defensible. That is more useful than filing a Schedule C and hoping.
