The IRS doesn't have a specific dollar limit for hobby income; instead, it focuses on profit motive: if you intend to make a profit, it's a business, but if it's for fun, it's a hobby, and you must report all income but can't deduct losses. Key is that you report all hobby income on Form 1040 as "other income," and if net earnings from self-employment are $400 or more, you owe self-employment tax, even if it's a side gig. The main difference from business is that you can't deduct hobby expenses (under current law) and must report all profits.
