After COVID, I started a part-time business as a personal assistant/girl Friday. I live in Hawaii and already had a General Excise Tax license. The family that I help pays me with checks, but I temperarily took over my friendʻs cleaning business for 2 weeks while she was on vacation. She paid me via Venmo. Can I just add those payments into my gross income when I file or do I have to do something different because it was payed through an app?
