There are benefits far beyond taxes that would lead you to incorporate -- such as protecting your personal assets. It doesn't matter how little you earn, if you are not doing business as a corporation (or LLC), your personal assets are at risk from judgment creditors.

If you're only earning $10,000 a year from your venture, you also have other important issues, namely, have you done the right business planning to make your business a success? If you're serious about moving forward with your business, speak to an attorney and an accountant to determine the business form (corporation or LLC) that's right for you.
