Consider the complete facts
A business generally operates with an objective of making a profit. The IRS considers multiple factors, including businesslike records, time and effort, expertise, changes intended to improve profitability, past success, history of income or losses, the size of profits, financial circumstances and personal enjoyment. No single factor decides every case.
An LLC, website or separate bank account may be relevant evidence of how you operate, but none automatically turns a hobby into a business. Conversely, an early loss does not automatically make a new venture a hobby.
Treat income and expenses correctly
Income from a hobby can still be taxable. Calling an activity recreational does not exempt receipts. Expense treatment differs materially from a for-profit business; do not assume hobby costs can offset wages or other income.
For a business, ordinary and necessary expenses still require support, and other limitations may apply to losses. A profit presumption in certain circumstances is not permission to ignore the full facts or guarantee every claimed loss. Discuss repeated losses and substantial personal enjoyment with a tax professional.
Create useful evidence while operating
Keep accurate books, a realistic plan, pricing records and evidence of steps taken to improve results. Track which customers pay, what services cost to deliver and why expenses are incurred. Document changes in marketing, pricing or operations when performance is weak.
At tax time, provide a complete history rather than only a list of deductions. If the activity changes from a pastime into a serious venture, review when that change occurred and how assets and expenses should be treated. Good records help establish the facts and make the reporting more accurate.
