Within the family of corporations, the Internal Revenue Service (IRS) grants tax free status to S-Corporations. It is strictly an IRS term. In the IRS code, there are several subchapters pertaining to corporations; Subchapter S identifies and regulates S-Corporations. In essence, S-Corporations are a pass through entity meaning that all income, losses, credits and special deductions are pass-through to the stockholders of the company.
Form 1120-S is an annual tax return filed on behalf of an S-Corporation. S-Corporations are pass through entities whereby the shareholders are assigned the respective income, deductions and tax credits via Schedule K-1 (Form 1120-S).
A K-1 is a reporting tool to the Internal Revenue Service. It is used by Partnerships, S-Corporations and Trusts to report the taxpayer’s share of income, deductions, and credits. A K-1 is similar to Form W-2 or 1099 in that the information provided informs the taxpayer of what has been reported to the Internal Revenue Service.
