Employee stock options can create costly tax reporting traps

Employee equity compensation can be a valuable part of a client’s compensation package, but it can also create complicated tax reporting issues. Incentive stock options (ISOs), restricted stock units (RSUs) and employee stock purchase plans (ESPPs) follow different tax rules, and the timing of an exercise, vesting event or sale can significantly affect the tax outcome.

For tax professionals, getting the reporting right often requires looking beyond a single tax document. Basis, holding periods, payroll reporting, broker statements and alternative minimum tax (AMT) considerations may all factor into the return. When those pieces aren’t reconciled, clients could report income twice, use an incorrect basis or encounter an unexpected tax liability.

Knowing where problems commonly occur can help tax pros prepare accurate returns, spot potential issues earlier and have more productive tax-planning conversations with clients.

RSUs: Reconcile compensation and basis

RSUs generally become taxable as compensation when they vest and the shares are transferred to the employee. The fair market value (FMV) of the shares is typically included as wages on Form W-2, Wage and Tax Statement. That compensation income is also important when determining the client’s basis in the shares.

Problems can arise when the employee later sells the stock.

Form 1099-B, Proceeds From Broker and Barter Exchange Transactions, may not provide all the information needed to determine the correct basis. If a return is prepared using an incorrect basis, income previously included in wages could effectively be taxed again as capital gain.

Tax pros should reconcile the client’s payroll information, brokerage statements and other available records instead of relying on one document. When appropriate, basis corrections and other adjustments can be reported on Form 8949, Sales and Other Dispositions of Capital Assets, before amounts flow to Schedule D (Form 1040), Capital Gains and Losses.

ISOs: Don’t overlook AMT

ISOs present a different challenge because their treatment for regular tax and AMT purposes can differ.

Exercising an ISO does not result in regular taxable income at the time of exercise. However, the difference between the exercise price and the FMV of the stock may result in an AMT adjustment. Depending on the client’s overall tax situation, Form 6251, Alternative Minimum Tax - Individuals, may be required.

Form 3921, Exercise of an Incentive Stock Option Under Section 422(b), provides information about the ISO exercise, including the exercise price and fair market value. Tax pros can use this information, along with the client’s other records, to evaluate potential AMT consequences and identify information that may be needed when the shares are eventually sold.

The disposition of ISO shares also requires careful attention to holding periods. Whether a sale is a qualifying or disqualifying disposition can affect the amount and character of income reported. A disqualifying disposition may result in compensation income as well as a capital gain or loss, while satisfying the applicable holding-period requirements may provide more favorable capital gain treatment.

ESPPs: Follow the transaction from purchase to sale

ESPPs can create similar questions involving compensation income, holding periods and capital gains.

Form 3922, Transfer of Stock Acquired Through an Employee Stock Purchase Plan Under Section 423(c), provides information about stock acquired through a qualifying ESPP. The tax consequences, however, depend in part on when the employee sells the shares.

Qualifying and disqualifying dispositions can produce different amounts of ordinary income and capital gain or loss. Determining the appropriate basis also requires accounting for amounts treated as compensation.

As with other forms of equity compensation, tax pros may need to piece together information from multiple sources, including Form W-2, Form 1099-B, Form 3922 and brokerage records. Reviewing the complete transaction can help prevent basis errors and incorrect income characterization.

Turn complicated reporting into better client service

Equity compensation also creates opportunities for proactive tax planning. Clients may not realize how much the timing of an ISO exercise, RSU sale or ESPP disposition can affect their tax situation until after the transaction has occurred.

For example, exercising ISOs could create AMT exposure. Selling shares before meeting an applicable holding period could change the character of the income. A client may also need help understanding why the amounts appearing on their Form W-2 and Form 1099-B don’t seem to match.
