The Priority of Distributions (Current vs. Accumulated E&P)
Current E&P First: Distributions are always deemed to come from current E&P first. If current E&P is positive, the distribution is a dividend even if accumulated E&P is negative.
E&P Adjustments: When calculating E&P from taxable income, you must add back tax-exempt items (like life insurance proceeds) and subtract non-deductible items (like federal taxes or the disallowed portion of meals). You do not adjust for standard business expenses like reasonable rent.
Substantially Disproportionate Redemptions (§302)
The Test: To be treated as a "sale" (capital gain) rather than a "dividend," a redemption must pass two mathematical hurdles:
The 50% Rule: The shareholder must own less than 50% of the total voting power after the redemption.
The 80% Rule: The new ownership % must be less than 80% of the old ownership %.
Family Attribution: You are deemed to own stock held by spouses, children, parents, and grandchildren—but not siblings.
Corporate Formations (§351)
Shareholder Basis: [Basis of Property Transferred] + [Gain Recognized] - [Boot Received] - [Liabilities Assumed by Corp].
Corporation Basis: The corporation generally takes a "carryover basis" (the shareholder's old basis), regardless of liabilities assumed, unless gain was recognized by the shareholder.
Corporate Liquidations
General Rule (Taxable): Liquidations are usually taxable to both the corporation and the shareholder. The shareholder recognizes gain/loss based on the FMV of property received vs. their stock basis. Their new basis in the property is its Fair Market Value (FMV).
80% Parent Rule (Tax-Deferred): If a parent corporation owns 80% or more of the liquidating subsidiary, the liquidation is tax-deferred. The parent takes a Carryover Basis in the assets.
Dividends and Ownership Levels
Ownership < 20%: Corporations usually include these dividends in both book and tax income (no book-tax difference), though they receive a 50% Dividends Received Deduction (DRD).
Ownership 20% – 80%: Entitles the corporation to a 65% DRD.
Example: If a company owns 30% of another and receives a $100,000 dividend, the deduction is $65,000.
Defining Income Taxes (ASC 740)
ASC 740 only applies to Income Taxes.
Non-Income Taxes: Value-Added Taxes (VAT), excise taxes, and franchise taxes based on capital (not income) do not fall under ASC 740.
Temporary vs. Permanent Differences
Permanent: Items like R&D tax credits, tax-exempt life insurance proceeds, and non-deductible fines. They affect the Effective Tax Rate (ETR) but never reverse.
Temporary: Items like capitalized inventory costs (§263A) or warranty reserves. These create Deferred Tax Assets (DTAs) or Liabilities (DTLs) because they will reverse in future years.
Calculating Deferred Tax Expense (DTE)
The Logic: You look at the net change in temporary differences.
Example Calculation:
Tax Depreciation > Book Depreciation by $50,000 (taxable difference).
Warranty reserve increased by $10,000 (deductible difference).
Net Difference: $40,000 taxable $\times$ 21% rate = $8,400 Deferred Tax Expense.
Uncertain Tax Positions
The Two-Step Process:
Recognition: Is it "More-Likely-Than-Not" (MLTN) (>50% chance) that the position will be sustained?
Measurement: Only if you pass Step 1 do you measure the amount of the benefit to record.
Service Contributions and Interests
Capital Interest: When a partner receives a capital interest for services, they must recognize the liquidation value as ordinary income. The holding period for this interest starts on the day it is received.
Profits Interest: Unlike capital interests, receiving a profits interest usually does not trigger immediate taxable income.
Basis and Debt Calculations
Purchasing an Interest: A partner’s starting outside basis is the purchase price plus their share of the entity’s debt. For example, paying $18,000 for an interest with a $5,000 debt share results in a $23,000 basis.
Property Contributions with Debt: Initial basis equals the basis of the property contributed, minus any debt relief, plus the partner's allocated share of total partnership debt (including nonrecourse loans).
Entity Classification: Under "check-the-box" rules, LLCs, general partnerships, and S-corps are all treated as flow-through entities.
Distributions and Gains/Losses
Gain Recognition: In an operating distribution, a partner only recognizes a gain if the cash received exceeds their outside basis.
Loss Recognition: Partners are strictly prohibited from recognizing a loss in an operating (non-liquidating) distribution.
Property Basis: In an operating distribution, property generally takes a carryover basis (the same basis the partnership had). In a liquidating distribution, the property's basis is adjusted to equal the partner's remaining outside basis after cash is accounted for.
Partnership Operations
Required Tax Year: Partnerships must determine their year-end using the Majority Interest test (>50% ownership) first, followed by the Principal Partners test, and finally the Least Aggregate Deferral method.

S-Corp Shareholder Restrictions
Only individuals (U.S. citizens or residents), estates, and certain trusts can own S-Corp stock.
Corporate Prohibition: Even if a corporation is owned by family members (like siblings), that corporation cannot be a shareholder in an S-Corp.
Termination Timing
Revocation Rule: To terminate an S-election for the current year, a revocation must be filed by the 15th day of the 3rd month (March 15 for calendar-year corps).
If filed later (e.g., April), the termination doesn't take effect until January 1 of the following year.
State Tax: Nexus & Sourcing
Income Tax Nexus: Created by physical presence, such as having employees, property, or independent agents performing services (like warranty repairs) in a state.
Sales vs. Use Tax: Sales tax is collected by the seller at the point of purchase. Use tax is a "backstop" paid by the buyer in their home state if the items were bought elsewhere and no (or lower) tax was paid.
Throwback Rule: If a company sells goods to a state where it has no nexus, those sales are "thrown back" to the state of origin for tax purposes.
Nowhere Sales: If a company has nexus in a state but that state simply doesn't have an income tax, those are "nowhere sales" and are not thrown back.
Scenario: "Lunar Corp" (S-Corp)
Shareholder: Maya (owns 50%)
Maya’s Starting Basis: $20,000
Beginning AAA Balance: $60,000
Accumulated C-Corp E&P: $40,000
Current Year Ordinary Income: $30,000
Total Distribution to Maya: $65,000
Step 1: Update Basis for Income
Maya must first increase her basis by her share of income before calculating the distribution.
$50\% \times \$30,000 = \mathbf{\$15,000}$ (This is taxable ordinary income).
Pre-Distribution Basis: $\$20,000 + \$15,000 = \mathbf{\$35,000}$.
Step 2: Update AAA
AAA starts at $\$60,000$ and is increased by the full corporate income of $\$30,000$.
Total AAA: $\mathbf{\$90,000}$.
Maya’s 50% share of the available AAA is $\$45,000$.
Step 3: The Distribution Waterfall
Maya receives $\$65,000$ total. We apply it in order:
From AAA ($\$45,000$):
This is tax-free up to her basis. Since her basis is $\$35,000$, the first $\$35,000$ is tax-free.
The remaining $\$10,000$ ($\$45,000 - \$35,000$) is a Capital Gain.
Maya's stock basis is now $0.
From Accumulated E&P ($\$20,000$):
Maya's 50% share of the $\$40,000$ E&P is $\$20,000$.
This is a Taxable Dividend.
Step 4: Total Income Recognized
Ordinary Income: $\$15,000$
Capital Gain: $\$10,000$
Dividend Income: $\$20,000$
Total: $\mathbf{\$45,000}$
Corporate Liquidations (The 80% Parent Rule)
General Rule: Corporations usually recognize gain/loss on liquidating distributions as if the property were sold at FMV.
The Exception (§332 & §337): If a parent corporation owns 80% or more of a subsidiary, neither the parent nor the subsidiary recognizes gain or loss upon liquidation.
Basis Impact: The parent takes a carryover basis in the assets received.
Partnership Distribution Mechanics
Operating (Current) Distributions: Generally non-taxable. Basis is reduced by cash first, then property (which takes a carryover basis).
Liquidating Distributions: A partner only recognizes a gain if cash received exceeds their outside basis. A loss can be recognized only if the assets received are strictly cash, inventory, or unrealized receivables.
International Taxation & FTC Baskets
Basket System: To prevent "averaging" high-tax and low-tax foreign income, the U.S. requires income to be separated into baskets (e.g., Passive, Foreign Branch, and General).
The 100% DRD: Dividends from certain foreign corporations are exempt from U.S. tax under the Dividends Received Deduction, but this also means any foreign taxes paid on those dividends cannot be used as a credit.
CFC & Subpart F: A U.S. shareholder must own 10% or more of a Controlled Foreign Corp to be subject to immediate taxation on the subsidiary’s passive income.
Wealth Transfer & The 3-Year "Estate Trap"
Life Insurance (§2035): If you gift a policy and die within 3 years, the full death benefit is pulled back into your estate.
Gift Tax Gross-Up: Any gift taxes paid on transfers within 3 years of death are added back to the gross estate to prevent deathbed tax avoidance.
Scenario: "Zenith Global" (U.S. Corporation)
U.S. Source Income: $2,400,000$
Passive Category (Foreign Interest): $150,000$ (Foreign Tax Paid: $12,000$)
Foreign Branch Income (Mexico): $450,000$ (Foreign Tax Paid: $110,000$)
Allocable Expenses (SG&A): $600,000$
U.S. Tax Rate: $21\%$
Subheading: Step-by-Step FTC Calculation
Determine Total Gross Income & Apportion Expenses:
Total Gross Income = $2.4\text{M} + 150\text{k} + 450\text{k} = \mathbf{3,000,000}$.
Passive SG&A: $(150,000 \div 3,000,000) \times 600,000 = \mathbf{30,000}$.
Branch SG&A: $(450,000 \div 3,000,000) \times 600,000 = \mathbf{90,000}$.
Calculate Taxable Income & Pre-Credit U.S. Tax:
Worldwide Taxable Income = $3,000,000 - 600,000 = \mathbf{2,400,000}$.
Pre-Credit U.S. Tax = $2,400,000 \times 21\% = \mathbf{504,000}$.
Apply Basket Limitations:
Passive Limit: $(\$150,000 \text{ Gross} - \$30,000 \text{ Exp}) \div \$2,400,000 \times \$504,000 = \mathbf{\$25,200}$.
Since the $12k paid is less than the $25.2k limit, the full $12,000 is creditable.
Branch Limit: $(\$450,000 \text{ Gross} - \$90,000 \text{ Exp}) \div \$2,400,000 \times \$504,000 = \mathbf{\$75,600}$.
Since the $110k paid is more than the $75.6k limit, only $75,600 is creditable.
Final Net U.S. Tax:
$\$504,000 - \$12,000 \text{ (Passive)} - \$75,600 \text{ (Branch)} = \mathbf{\$416,400}$.
Scenario: "The Silas Estate"
The Gift: Silas gifted a life insurance policy (worth $4\text{M}$ then) to his children.
The Death: Silas died unexpectedly 2 years later.
The Payout: Life insurance paid out $15,000,000$ to the children.
Gift Tax Paid: Silas paid $1,200,000$ in gift taxes on the original $4\text{M}$ transfer.
Probate Estate: Other assets worth $22,000,000$.
Prior Taxable Gifts: $10,000,000$ (from years before the insurance gift).
Subheading: Calculating Cumulative Taxable Transfers
Identify Inclusions for Gross Estate:
Probate Assets: $22,000,000$
Life Insurance (3-year rule): +$15,000,000$ (Face value)
Gift Tax Paid (3-year rule): +$1,200,000$ (Gross-up)
Gross Estate = $38,200,000$
Determine Adjusted Taxable Gifts:
Include prior gifts ($10,000,000$).
Exclude the $4\text{M}$ insurance gift value to prevent double-taxing the $15\text{M}$ already in the estate.
Final Calculation:
$38,200,000 \text{ (Gross Estate)} + 10,000,000 \text{ (Adj. Gifts)} = \mathbf{48,200,000}$.
Scenario: "Atlas Global"
U.S. Taxable Income: $2,000,000$
Passive Basket Income: $150,000$
Total Gross Income: $2,500,000$
Total SG&A Expenses: $400,000$
U.S. Tax Rate: $21\%$
Apportion Expenses to Passive Basket: $(\$150,000 \div \$2,500,000) \times \$400,000 = \mathbf{\$24,000}$.
Calculate Passive Taxable Income: $\$150,000 - \$24,000 = \mathbf{\$126,000}$.
Calculate Total Taxable Income & Pre-Credit Tax: $\$2,500,000 - \$400,000 = \$2,100,000$ taxable income.
$\$2,100,000 \times 21\% = \mathbf{\$441,000}$ Pre-Credit Tax.
Calculate Passive FTC Limit: $(\$126,000 \div \$2,100,000) \times \$441,000 = \mathbf{\$26,460}$.
