I am currently making a decent amount of income from affiliate marketing (people go to my site, click my link for product X, and if they buy product X, I make a percentage of the sale). I am wondering if I should contact an accountant since I am on pace to make over $100,000 this year ... all on the side.
If it helps, I have been using about 5% of my earnings to reinvest in my online businesses ... but it will probably be more soon.
