My business which is a single person LLC, employed services of an S Corp for about 18000 dollars in 2014. Do i need to issue a 1099-MISC to this corporation? I read that corporations are exempt from 1099-MISC, If corporations are exempt from 1099-MISC how are they taxed for this income?
You do not need to provide a corporation (including an S-corporation) a Form 1099-MISC.
If corporations are exempt from 1099-MISC how are they taxed for this income?
You shouldn't report income based on Forms 1099-MISC. Rather, you should keep adequate records of your business income and expenses and base your return on those records. One reason is because even for non-corporations, not all people who should issue Forms 1099-MISC do. Another reason is much of their income is not required to be on a Form 1099-MISC if provided to a nonbusiness. As an example, a heating and air condition company, or a pest control company, providing services to private homes would not receive any Forms 1099-MISC, but are still required to report all of their income.
