Welcome to S Corporations!
Hello future CPAs! Today we are diving into S Corporations. If you have already studied C Corporations and Partnerships, you will find that S Corps are like a "hybrid" of the two. They offer the legal protection of a corporation but the "flow-through" tax benefits of a partnership. This is a high-yield topic for the REG exam, so let’s break it down into simple, bite-sized pieces. Don't worry if it seems like a lot of rules at first—we will take it one step at a time!
1. What is an S Corporation? (The "Exclusive Club")
Think of an S Corp as a regular corporation that has asked the IRS for a special "tax status." Instead of the corporation paying taxes (double taxation), the income "flows through" to the shareholders, who report it on their personal tax returns.
Eligibility Requirements
An eligible domestic S corporation generally has no more than 100 shareholders, eligible individuals, estates, specified trusts or qualifying section 401(a)/501(c)(3) exempt organizations, no direct nonresident-alien shareholder, and one economic class of stock. Voting rights may differ, but distribution and liquidation rights must be identical. The statutory family-counting rule includes a common ancestor, lineal descendants and spouses, subject to the six-generation test; not every relative automatically counts as one.
Making the Election (Form 2553)
File Form 2553 with required shareholder consents during the preceding tax year or generally within two months and 15 days after the beginning of the year for which the election is intended. A calendar-year deadline is generally March 15, adjusted for weekends/holidays. Late-election relief may be available; lateness does not always force next-year effectiveness.

2. S Corp Operations: How Income Flows Through
Just like a partnership, an S Corp is a flow-through entity. It files an information return (Form 1120-S) and provides each shareholder with a Schedule K-1.
Ordinary Income vs. Separately Stated Items
Imagine a suitcase. Some items (like ordinary business income) get thrown into the main compartment. Other items (like charitable contributions or capital gains) need their own special side pockets because they are treated differently on an individual's tax return.
Ordinary Business Income: Sales revenue minus standard operating expenses (rent, utilities, employee wages).
Separately Stated Items: These are items that might affect shareholders differently based on their personal tax situation. They include:
• Rental income/loss
• Interest and Dividend income
• Capital Gains and Losses
• Section 179 deductions
• Charitable contributions
Common Mistake Alert: Shareholders do not pay self-employment tax on their share of S Corp ordinary income. This is a huge difference from partnerships! However, if a shareholder is also an employee, they must be paid a "reasonable salary," which is subject to payroll taxes.
Key Takeaway: Income flows to shareholders based on their percentage of ownership on a per-share, per-day basis. If you own 50% of the stock for the whole year, you get 50% of the profit.
3. The "Golden Rule" of Basis
Basis is one of the most important concepts for the REG exam. It tracks how much "after-tax" money you have in the company. It limits how much loss you can deduct and how much money you can take out tax-free.
Calculating Shareholder Basis (The Formula)
Stock basis normally increases for contributions and taxable/tax-exempt income, then decreases for distributions, nondeductible noncapital expenses, and losses/deductions, in that order. An eligible election can change the last two. Qualifying direct shareholder loans create separate debt basis, not stock basis; corporate bank borrowing or a guarantee alone generally creates neither. A property-for-stock transfer requires its own section 351/control and liability analysis.
Did you know? Tax-exempt income (like proceeds from a life insurance policy) increases your basis. Even though you don't pay tax on it, it increases your "investment" in the company!
The Debt Basis Rule (Crucial for the Exam!)
Stock basis normally increases for contributions and taxable/tax-exempt income, then decreases for distributions, nondeductible noncapital expenses, and losses/deductions, in that order. An eligible election can change the last two. Qualifying direct shareholder loans create separate debt basis, not stock basis; corporate bank borrowing or a guarantee alone generally creates neither. A property-for-stock transfer requires its own section 351/control and liability analysis.

4. Distributions: When is the Cash Taxable?
This depends on whether the S Corp was always an S Corp or if it used to be a C Corp.
Scenario A: S Corp has no "Accumulated Earnings & Profits" (Always an S Corp)
For a nonliquidating cash distribution with no accumulated C-corporation E&P, the amount reduces stock basis tax-free, then produces gain to the extent it exceeds stock basis (generally capital gain if the stock is a capital asset). Debt basis does not shelter distributions. With E&P and no special election or legacy adjustments, first apply the AAA portion under that same basis/gain rule, then dividend treatment to E&P, then the remaining basis/gain rule. AAA is not a guarantee of tax-free treatment.
Scenario B: S Corp has "Accumulated Earnings & Profits" (Used to be a C Corp)
For a nonliquidating cash distribution with no accumulated C-corporation E&P, the amount reduces stock basis tax-free, then produces gain to the extent it exceeds stock basis (generally capital gain if the stock is a capital asset). Debt basis does not shelter distributions. With E&P and no special election or legacy adjustments, first apply the AAA portion under that same basis/gain rule, then dividend treatment to E&P, then the remaining basis/gain rule. AAA is not a guarantee of tax-free treatment.

5. Terminating the S Corp Status
How does the "exclusive club" membership end? It can happen in three ways:
1. Voluntary Revocation: Shareholders holding more than 50% of the stock agree to quit.
2. Failure to Meet Eligibility: For example, you accidentally sell stock to a corporation or a 101st person. The status ends immediately on that day.
3. Passive Income Penalty: If the S Corp has old C Corp E&P AND more than 25% of its gross receipts are passive (like interest/dividends) for three consecutive years, the status is lost on the start of the fourth year.
After revocation or termination, a new S election generally cannot take effect before the fifth taxable year beginning after the first taxable year for which termination was effective, unless the IRS consents. Count taxable years, not five years from the calendar date.
Summary: S Corporations provide a powerful way to avoid double taxation. Remember the 100-shareholder rule, the direct-loan rule for debt basis, and the "AAA before E&P" rule for distributions, and you will be well on your way to mastering this section of the REG exam! You've got this!
