This income will be reported on Schedule C which is part of your overall tax return. This also means you will be subject to SE Tax which are 15.3% of your profit. If you did not pay Self Employment (SE) Taxes in 2025, and if you plan to do this again in 2026, it may be a good idea and avoid penalties.
