So recently I started up a forum. I only have a couple of members so far and very few posts, but it seems that as the days are going by, things are picking up just a little bit each day and so on. I've put a couple of ads on the site, but it's pretty much a labor of love at this point... However, if things keep picking up like this, I'll likely get a decent amount of active members and will start bringing in some money. In the future, I do also plan to sell merchandise, as well as accept donations with certain rewards for donations of a certain amount, and so on... I'm sure states may vary somewhat, so it could depend slightly on where I'm located... But when exactly does this website (or any other similar sites I may start) meet the criteria of what is considered a business? After how much would I start to pay taxes? Do I have to meet that amount to be considered a business, or is simply selling merchandise and accepting donations to my site enough to meet the definition of business? I'm a young guy, and this is my first real attempt at a website, especially a viable/successful one, and this is all kind of foreign to me... Any help would be greatly appreciated!
