S-Corporation Election Guide: How to Elect S-Corp Status and Save on Self-Employment Taxes

S-Corporation Election Guide: How to Elect and Benefit from S-Corp Tax Status

An S-Corporation is not a separate business structure — it is a federal tax election that allows eligible corporations (and in some cases LLCs) to be taxed as pass-through entities, avoiding the corporate-level income tax that applies to C-Corporations. S-Corp status can result in meaningful self-employment tax savings for business owners who are actively working in their company, making it one of the most popular tax strategies for small and mid-sized businesses in the United States.

What Is an S-Corporation?

Under the Internal Revenue Code, an S-Corporation (named after Subchapter S of Chapter 1 of the IRC) is a corporation that has elected to pass its income, losses, deductions, and credits directly through to its shareholders, who report them on their individual tax returns. The S-Corp itself does not pay federal income tax on its net income (with some exceptions for built-in gains and certain passive income). This eliminates the double taxation that affects C-Corporations.

S-Corporation Eligibility Requirements

Not every corporation qualifies for S-Corp status. To elect S-Corp taxation under IRS rules, the corporation must meet all of the following requirements:

• Must be a domestic corporation incorporated in the United States
• No more than 100 shareholders at any time during the tax year
• All shareholders must be eligible: only U.S. citizens, lawful permanent residents, certain trusts, and estates may be shareholders — foreign nationals and other corporations generally cannot be shareholders (with limited exceptions)
• Only one class of stock — S-Corps cannot have preferred stock or multiple classes of stock with different economic rights (voting differences are permitted)
• Not an ineligible corporation type — certain financial institutions, insurance companies, and domestic international sales corporations cannot elect S-Corp status

How to File IRS Form 2553 (S-Corp Election)

To elect S-Corp status, the corporation must file IRS Form 2553, Election by a Small Business Corporation. Key rules:

• New corporations: Form 2553 must be filed no later than 2 months and 15 days after the beginning of the first tax year the election is to take effect (i.e., within 75 days of your date of incorporation for calendar-year corporations)
• Existing corporations: To elect for the following tax year, file Form 2553 any time during the preceding tax year; to elect for the current year, file within 2 months and 15 days of the start of that tax year
• All shareholders must sign Form 2553 consenting to the election
• Late election relief: The IRS provides relief for late S-Corp elections if the corporation can show reasonable cause (Rev. Proc. 2013-30). Many businesses successfully elect S-Corp status retroactively

The Reasonable Compensation Rule

The primary self-employment tax benefit of S-Corp status is that only the shareholders' wages (salary) are subject to FICA payroll taxes (15.3% for Social Security and Medicare on wages up to the Social Security wage base, plus 2.9% for Medicare on all wages). Distributions (profit distributions beyond wages) are not subject to self-employment taxes.

However, the IRS requires that shareholder-employees who perform services for the S-Corp must receive reasonable compensation before taking distributions. "Reasonable" generally means what you would pay a non-owner employee to perform the same work. The IRS actively audits S-Corps that pay little or no salary to working shareholders while making large distributions — this is considered an attempt to avoid payroll taxes and can result in reclassification of distributions as wages plus penalties.

Example: If your S-Corp earns $200,000 in net income after expenses, and a reasonable salary for your role is $80,000, you pay payroll taxes on the $80,000 salary. The remaining $120,000 can be taken as a distribution subject only to income tax (not payroll taxes) — saving you approximately $18,360 in self-employment taxes.

Pass-Through Taxation: How It Works

S-Corp income, losses, deductions, and credits pass through to shareholders in proportion to their stock ownership. Each shareholder receives a Schedule K-1 showing their share of the S-Corp's income and deductions, which they report on their individual Form 1040. Key features of S-Corp pass-through taxation include:

• Income is taxed at each shareholder's individual tax rate (up to 37% federally)
• Losses can generally be deducted against other income (subject to basis, at-risk, and passive activity limitations)
• Each shareholder maintains a "stock basis" that affects their ability to deduct losses and the taxability of distributions
• Qualified Business Income (QBI) deduction under Section 199A may allow eligible shareholders to deduct up to 20% of their S-Corp income

S-Corp vs. LLC vs. C-Corp

Choosing the right structure involves comparing key characteristics:

• S-Corp: Pass-through taxation + self-employment tax savings via salary/distribution split; limited to 100 U.S. shareholders; one class of stock; shareholder management; ideal for profitable owner-operated businesses
• LLC taxed as S-Corp: An LLC can make an S-Corp tax election (first electing to be taxed as a corporation, then electing S-Corp status). This combines LLC structural flexibility with S-Corp tax benefits
• C-Corp: Flat 21% corporate tax; unlimited shareholders; multiple stock classes; ideal for venture-backed startups and companies planning public offerings; QSBS tax exclusion available
• LLC (default): Self-employment taxes on all net income but maximum flexibility; simplest administration; ideal for smaller businesses or those with losses

Terminating an S-Corp Election

An S-Corp election can be terminated voluntarily (by shareholder consent) or involuntarily (if the corporation violates any eligibility requirement — for example, a shareholder transfers stock to an ineligible person). After termination, the corporation must wait 5 years before it can re-elect S-Corp status, unless the IRS grants an exception.
