Section 302 Stock Redemption: How Closely-Held C Corporations Avoid Surprise Dividend Treatment
Section 302 of the Internal Revenue Code decides whether a closely-held C corporation's stock redemption is taxed as a capital sale or a full-amount dividend. This guide explains the three Section 302(b) tests, the Section 318 attribution traps that ensnare family-owned companies, the 10-year family-attribution waiver, and the partial-liquidation safe harbor under Section 302(b)(4).
Section 382 NOL Limitation After Ownership Change: How Venture-Backed Startups Preserve Net Operating Loss Carryforwards Through Equity Rounds
Section 382 caps a startup's pre-ownership-change net operating loss deductions at the pre-change fair market value multiplied by the long-term tax-exempt rate (about 3.56 percent in February 2026), triggered when 5 percent shareholders collectively gain more than 50 percentage points over a rolling three-year testing period.
Section 83(i) Tax Deferral on Private Company Stock: A Five-Year Lifeline for Pre-IPO Employees with RSUs and NSOs
Section 83(i) lets qualified employees of qualified private companies defer federal income tax on RSU settlements and NSO exercises for up to five years. The 80 percent grant rule, mandatory escrow, and 30-day election deadline explain why adoption stays in the single digits — and when the election still pays off.
The ISO AMT Trap in 2026: How Tech Employees Get Hit With Six-Figure Tax Bills on Stock They Can't Sell
Exercising and holding ISOs adds the bargain element to AMTI on Form 6251 Line 2i, which can produce a six-figure tax bill before a single share is sold. A 2026 guide to the tightened AMT exemption phase-out ($500K single / $1M MFJ at 50¢ per dollar), the qualifying disposition rules under IRC §422, and the planning moves — AMT crossover exercise, §83(b) early exercise, same-year disqualifying sale, and multi-year laddering — that keep tech employees out of the trap.
ISO AMT in 2026: Bargain Element, Form 6251 Line 2i, and the OBBBA Phase-Out Cliff
Under OBBBA, the 2026 AMT exemption phases out at $500K single / $1M joint with a 50-cent rate, doubling the stealth bracket on ISO exercises. Here is exactly how the bargain element flows into Form 6251 line 2i, when a same-year disqualifying disposition eliminates the AMT adjustment, and how to plan exercises to avoid a six-figure phantom-income tax bill.
Section 1244 Small Business Stock: How Founders Convert a Failed Startup Into a $50,000 Ordinary Loss
Section 1244 lets eligible founders and early investors convert up to $50,000 ($100,000 joint) of capital loss on failed C-corporation stock into ordinary loss deductible against W-2 wages, freelance income, or interest. This guide covers who qualifies, the $1 million capital ceiling, Form 4797 reporting, and the formation steps that keep the deduction defensible.
Section 1259 Constructive Sales: How Hedging Appreciated Stock Can Trigger a Phantom Tax Bill
Section 1259 treats short-against-the-box trades, equity swaps, and tight collars on appreciated stock as constructive sales — taxable today, even with no proceeds. Covers the variable prepaid forward workaround, the 30-day closing exception, and the related-party trap.
Section 351 Tax-Free Incorporation: The 80% Control Test, Boot Traps, and QSBS for Founders
Section 351 lets founders incorporate without immediate tax only if the transferor group owns 80% of voting power and every non-voting class right after the exchange. Miss the control test, contribute services instead of property, or assume liabilities greater than basis, and the gain surfaces anyway. A practical playbook covering boot, the Section 357(c) trap, basis carryover under Sections 358 and 362, and how to preserve QSBS eligibility under Section 1202.
Section 368 Tax-Free Reorganizations: How Type A Mergers, Type B Stock Swaps, and Type C Asset Deals Defer Tax in Strategic M&A

This guide covers the 40% Continuity of Interest test, Type A statutory mergers, Type B stock-for-stock swaps with the 80% control requirement, Type C asset deals, and forward/reverse triangular merger structures with their consideration limits.
Section 83(i) Explained: A Five-Year Tax Deferral for Private-Company RSUs and NSOs
Section 83(i) lets qualified rank-and-file employees at eligible private companies defer federal income tax on RSU vests and NSO exercises for up to five years, but FICA is still due at vesting, the 30-day election window is unforgiving, and the 80 percent broad-based grant rule keeps most startups from offering it.
Section 280G Golden Parachute Payments: The 3× Trigger, 20% Excise Tax, and the Private Company Cleansing Vote
Section 280G disallows the corporate deduction and imposes a 20% Section 4999 excise tax once parachute payments to a disqualified individual reach three times the executive's five-year average W-2 compensation, with the penalty applying to everything above 1× the base amount. Private companies can eliminate the consequences entirely through a 75% disinterested shareholder vote paired with conditional waivers signed before closing.
