Stock Options and RSUs for US Expats: How to Report Them

Stock Compensation Reporting Overview

How Are RSUs Taxed for US Expats?

Restricted Stock Units are promises from an employer to deliver company shares or their cash equivalent once certain conditions are satisfied.

These conditions commonly involve remaining employed for a specified period.

For US tax purposes, RSUs are generally not taxable when initially granted. Instead, taxation usually occurs when the shares vest and are delivered to the employee.

The fair market value of the shares at that time becomes ordinary employment income.

Example: RSUs Vesting While Living Abroad

Suppose an American employee working in Italy receives 200 RSUs from their employer.

When the shares vest:

• Number of shares: 200
• Fair market value per share: $50
• Total taxable compensation: $10,000

The employee generally reports $10,000 in employment income on their US tax return.

This amount may be taxable even if the employee keeps the shares rather than selling them.

If the employer withholds shares to cover taxes, the employee generally still reports the full taxable compensation rather than only the value of shares received after withholding.

The amount included in income also generally establishes the employee’s tax basis in the shares.

How Are Stock Options Taxed for US Expats?

Stock options give employees the right to purchase company shares at a predetermined price, commonly called the exercise or strike price.

US tax treatment depends primarily on the type of option.

Nonqualified Stock Options (NSOs)

Most nonqualified stock options are taxable when exercised, assuming they did not have a readily determinable fair market value when granted and the acquired shares are substantially vested.

The taxable amount is generally the difference between the stock’s fair market value and the exercise price.

Example:

An American employee in France exercises 100 stock options with the following values:

The $4,000 difference is generally ordinary employment income.

If the employee later sells the shares, any additional gain or loss is calculated separately.

Incentive Stock Options (ISOs)

Incentive Stock Options receive different US federal tax treatment when they satisfy specific requirements.

Generally:

• Granting an ISO does not create taxable income.
• Exercising an ISO does not ordinarily create regular federal income tax.
• The exercise spread may trigger an Alternative Minimum Tax (AMT) adjustment.
• Selling the shares may produce capital gains or ordinary income depending on the holding period.

To qualify for favorable long-term capital gain treatment, the employee generally must hold the shares for more than two years after the grant date and more than one year after exercise.

ISOs also have statutory eligibility requirements, so options issued by foreign employers should not automatically be assumed to qualify.

Employees exercising qualifying ISOs may need to consider Form 6251 for AMT purposes.

What Happens When You Sell RSUs or Stock Option Shares?

Selling shares acquired through RSUs or stock options generally creates a separate taxable event.

The important distinction is between employment income already recognized and the subsequent investment gain or loss.

For ordinary RSUs, the tax basis is generally the fair market value included in income when the shares were delivered.

For typical NSOs, the basis generally includes the exercise price plus the amount previously recognized as compensation.

Example: Selling RSU Shares

Suppose an American living in Spain receives 100 RSU shares that vest at $80 each.

The employee recognizes $8,000 of ordinary employment income.

Six months later, the employee sells all 100 shares for $95 each.

The $8,000 was already treated as employment income. Only the additional $1,500 is generally reported as capital gain, assuming no transaction costs or other adjustments.

Selling shares held for more than one year generally produces a long-term capital gain or loss.

An important reporting issue arises when a brokerage statement shows an incorrect or incomplete cost basis. Failing to adjust the basis can result in the same compensation being taxed twice.

How to Report Stock Options and RSUs on Your US Tax Return

Reporting equity compensation involves identifying the taxable event, calculating employment income, and separately reporting any share sales.

Step 1: Identify Your Equity Compensation

Collect your employer’s equity award statements, vesting schedules, exercise confirmations, and brokerage statements.

Determine whether you received RSUs, NSOs, ISOs, or another form of stock compensation.

Step 2: Calculate Taxable Employment Income

For RSUs, identify the fair market value when the shares became taxable.

For NSOs, calculate the difference between the exercise price and the applicable market value.

Convert foreign-currency amounts into US dollars using an appropriate exchange rate for the relevant transaction.

Step 3: Report Employment Income on Form 1040

Taxable equity compensation is generally included with wages or other employment income.

US employers commonly report this compensation on Form W-2.

Foreign employers may provide local payroll statements instead, requiring the taxpayer to calculate and report the appropriate US taxable amount.

Step 4: Report Share Sales on Form 8949 and Schedule D

When shares are sold, report the transaction using Form 8949 and Schedule D, as applicable.

Verify the acquisition date, sale proceeds, holding period, and adjusted tax basis.

Step 5: Review Foreign Tax Credits and Additional Reporting

Determine whether foreign taxes paid on the compensation or share sale qualify for relief from double taxation.

Also review whether the account holding the shares creates separate foreign financial account reporting obligations.

Can Foreign Tax Credits Reduce Double Taxation?

US expats may face taxation in both the United States and their country of residence.

For example, Germany might tax RSU income when shares vest, while the United States also requires the employee to report that compensation.

The Foreign Tax Credit may help reduce US tax on income that has also been taxed abroad.

However, foreign tax credits are subject to sourcing rules, separate income categories, and other limitations.

Stock compensation may relate to services performed in multiple countries. Consequently, the country where an employee lives when shares vest does not necessarily determine where all the compensation was earned.

For equity awards involving international transfers, employers and tax preparers may need to examine the employee’s work locations during the relevant service period.

The Foreign Earned Income Exclusion may also apply to qualifying employment compensation, but it does not generally exclude capital gains from selling shares. Income excluded under the FEIE also cannot generate a foreign tax credit for the foreign taxes attributable to that excluded income.

Do Stock Options and RSUs Trigger FBAR or FATCA Reporting?

Stock compensation can create reporting obligations beyond the income tax return.

If shares or proceeds are held in a foreign financial account, that account may need to be considered under the FBAR reporting requirements.

An FBAR is generally required when the aggregate maximum value of reportable foreign financial accounts exceeds $10,000 at any point during the calendar year.

Certain foreign-held shares, brokerage accounts, or equity interests may also be relevant to FATCA reporting on Form 8938, depending on the assets, account arrangements, and applicable thresholds.

Unvested RSUs and unexercised stock options should not automatically be treated as reportable foreign accounts. Their reporting treatment depends on the legal rights and assets involved.

Common Stock Compensation Reporting Mistakes

US expats should pay particular attention to the following issues:

1. Reporting income only when shares are sold. RSUs and NSOs may create taxable employment income before a sale occurs.
2. Using an incorrect cost basis. Brokerage statements may omit compensation previously included in taxable income.
3. Ignoring foreign withholding taxes. Foreign taxes should be reviewed for potential credit eligibility rather than assumed to offset US taxes automatically.
4. Overlooking cross-border employment periods. Stock compensation earned while working in different countries may require income allocation.
5. Missing foreign account reporting. Shares held through overseas brokerage arrangements may create separate reporting obligations.

Keeping complete records of grants, vesting dates, exercises, sales, and foreign taxes helps reduce these errors.
