The short version
An offer to buy your employee shares can create a useful chance to obtain cash. Before accepting, the tax review needs to identify what you own, who is buying it, and whether you must exercise an option or receive shares before the sale. Those details can divide the proceeds between compensation and investment gain, or bring corporate redemption rules into the analysis.
The offer price and the amount deposited into your bank account are not enough to prepare the return. Sheepdog Tax’s review connects the award documents, transaction agreement, payroll reporting, and tax basis before the transaction is completed.
What the law actually says
For an ordinary sale of shares, Internal Revenue Code section 1001 generally measures gain by subtracting adjusted basis from the amount realized. Basis is the tax investment in the shares. For employee stock, it may include compensation already recognized as well as cash paid to acquire the shares.
The compensation event must be identified separately. Treasury Regulation 1.83-7(a) applies section 83 when a nonstatutory option without a readily ascertainable value at grant is exercised or otherwise disposed of. If an employee exercises into fully vested stock, the spread between value and exercise price normally becomes compensation. A subsequent sale does not turn that compensation into capital gain.
An incentive stock option (ISO) has separate requirements. A sale before the periods in section 422(a)(1) have expired can be a disqualifying disposition, causing compensation income under the applicable rules. A tender offer does not suspend those holding requirements. The review should also identify restricted shares, restricted stock units, and any earlier election or deferral rather than assuming every employee holds the same kind of stock.
The buyer matters
If an outside investor purchases existing shares, the analysis generally begins with a stock sale. If the issuing corporation buys back its own shares, section 302 asks whether the redemption qualifies for exchange treatment. The ownership tests can count stock attributed from related persons or other interests, rather than only the shares shown in the employee’s account.
If exchange treatment does not apply, section 302(d) generally sends the distribution to section 301. That can produce dividend treatment to the extent the distribution is a dividend under the applicable rules, followed by the basis and gain rules for the remaining distribution. It is not safe to assume that every issuer buyback produces a capital gain calculated by subtracting the sold shares’ basis from cash received.
Sheepdog Tax therefore reviews the purchaser, any company participation, the shares being transferred, and the employee’s remaining ownership. The transaction’s label, including “tender offer” or “secondary sale,” does not by itself settle its federal tax classification. Company counsel should address transfer restrictions and transaction eligibility; a tax analysis does not authorize a sale.
How the numbers can differ from the bank deposit
Consider a hypothetical employee who must first exercise 1,000 vested nonstatutory options before selling the shares to an unrelated outside investor. Assume no readily ascertainable option value at grant, no special deferral, a $5 exercise price, a $30 share value at exercise, and a later $32 sale price. Ignore fees and withholding for this illustration.
The exercise costs $5,000 and creates $25,000 of compensation. As explained in IRS Publication 525, Nonstatutory Stock Options, basis includes both the option price and compensation included in income. The shares therefore have $30,000 of basis. Selling for $32,000 produces $2,000 of additional gain. Its capital-gain holding period must be tested separately.
Cash after the $5,000 exercise cost is $27,000 before tax and fees. The return may report $25,000 of compensation plus $2,000 of sale gain. Reporting all $32,000 as sale gain would ignore basis. Reporting only the $27,000 bank-related amount without separating its character would miss the compensation analysis.
Actual payroll withholding and transaction costs must then be reconciled. Withholding is a payment toward the tax, not a second deduction from income. The broader cash-reconciliation issue also appears in employment settlement planning, although settlement characterization and legal-fee rules do not govern an employee stock sale.
Holding periods and a redemption test
Scroll the table sideways to read all columns, including sources.
| Question | Quantified rule | Authority |
|---|---|---|
| When is ordinary capital-asset gain long term? | The asset must be held for more than 1 year, subject to special rules | Section 1222(3) |
| What periods apply to an ISO qualifying disposition? | No disposition within 2 years from option grant or within 1 year after transfer of the shares | Section 422(a)(1) |
| What ownership limits appear in the substantially disproportionate redemption test? | After redemption, voting ownership must be below 50%, and the post-redemption voting percentage must be less than 80% of its prior percentage | Section 302(b)(2) |
The last row is only part of that redemption test. Section 302 also imposes a common-stock reduction test, addresses a series of redemptions, and applies constructive-ownership rules. Other exchange-treatment routes may apply. These figures are prompts for an ownership analysis, not a shortcut for approving an issuer buyback.
What the transaction review should resolve
The review should produce an award-by-award schedule showing the shares acquired, cash paid, compensation recognized, adjusted basis, sale proceeds, and remaining holdings. The instructions for Form 8949 provide for reporting adjustments when broker information does not show the correct basis. Payroll records and broker supplements need to support any correction; the same compensation should not be taxed again through an understated basis.
State exposure is a separate part of the projection. The employee option-sourcing example explains why past work locations can matter even after a move. That article concerns a specific nonstatutory-option fact pattern. It does not establish the sourcing of every tender-offer payment or later capital gain.
Finally, a payment plan is needed for the tax year in which income is recognized. Publication 505 (2026) explains that withholding and estimated payments interact with the full year’s tax. The projection should account for both the compensation and the sale, rather than assuming a transaction administrator’s withholding settles the entire liability.

The option-sourcing article linked above is useful when employment crossed state or national borders. The settlement cash-reconciliation article illustrates why gross income, amounts paid to others, withholding, and retained cash must be distinguished. Each involves its own legal rules; neither replaces a review of the share-sale agreement.
