The S corporation business structure offers many advantages, including limited liability for owners and no double taxation (at least at the federal level). But not all businesses are eligible • and, with the new 21% flat income tax rate that now applies to C corporations, S corps may not be quite as attractive as they once were.
If you run your business as an S corporation, you’re probably both a shareholder and an employee. As such, the corporation pays you a salary that reflects the work you do for the business — and you (and your company) must remit payroll tax on some or all of your wages.
The IRS may object to the compensation of C corporation shareholder-employees. If it’s deemed too high — or not “reasonable” under the circumstances — the IRS could force you to make adjustments that increase taxes.
