Years ago I used to buy and sell domains here (and elsewhere) that supplemented my income which came from being a freelance web designer. For taxes, I was always sure to pay taxes on any domain profits, by merging both by domain income with my main businesses profits (web design services). Since the domain investments were pretty cheap, when it came to taxes, I would either expense the domain purchases or treated them as inventory. I was never a high volume seller and the domains I purchased were usually under $300. However, for 2021, I am considering getting back into domaining, even though I have a newer business venture which is selling records and cd's. My question is (for anyone here who may have more experience) couldn't I just sell domains alongside my record shop business, even though my record shop business obviously has nothing to do with domaining? When it comes to taxes, isn't that perfectly acceptable so long as I keep track of all domain expenses and purchases? I'm only asking because I really, really don't want to create a separate business/entity solely for my domain investments. Any insights here would be much appreciated!
